The Australian Football League (AFL)


The Australian Football League (AFL) is both the elite Australian national competition in the sport of Australian Rules Football and its highest governing body.
The AFL is the most attended professional sporting league in Australia: it is the most popular sport competition in terms of attendances and TV ratings of the nation. The previous three AFL Premiership Seasons have had a total regular season attendance of over six million (currently the 10th most attended professional sports league in the world) and the average attendance of over 36,000 (the second highest of any professional sports league in the world).
The 16 teams play against each other in 22 rounds between late March and early September in a non-divisional format. These matches are followed by a series of finals matches which culminate in the two best teams playing off for the Premiership in the AFL Grand Final, the best attended domestic club championship event in the world.
The AFL began as a breakway league from the Victorian Football Association (VFA) in 1896 and evolved from the Victorian domestic competition known as the Victorian Football League (VFL). Since 1982, it has grown into a national competition and was rebranded as the Australian Football League in 1990 and today has teams based in five of the six Australian states. Since becoming a national competition, the AFL has gained considerable media and financial strength, as well as control over the game at most levels. The expansion of the AFL in the 1980s effectively ended 70-year-long competition for public interest with its former rival state leagues, the SANFL, the WAFL and VFA (which became the VFL in 1996). In recent times, most of these leagues and clubs have either sought or subsequently been granted licences to compete in the AFL and formed affiliations with the AFL to field its reserves sides and developmental players.
The AFL Commission, which runs the league assumed the role of governing body for the sport of Australian rules football in Australia in 1993 when it dissolved the Australian National Football Council. It is now responsible for the Laws of Australian Football through the AFL Rules Committee (consisting of members from the AFL Players Association). The AFL also became the defacto world governing body in 2002 when it negotiated the disbanding of the International Australian Football Council. Since 2000, through the commission, the AFL has pushed for all affiliated leagues and bodies to co-brand with the league as well as refer to the sport as "AFL" in preference to its official name of "Australian Football".


History
Australian rules football dates back to 1858, when Tom Wills began to devise the rules of the code. Melbourne Football Club was formed May 14, 1859. On May 17, 1859, at the Parade Hotel in East Melbourne, Wills, W.J. Hammersley and J.B. Thompson wrote the first set of written rules for Australian rules football. By 1866, several other clubs had also adopted an updated version of Melbourne's rules. In 1877, the amateur Victorian Football Association was established.


VFL begins
The Victorian Football League was established in 1896 when several clubs broke away from the Victorian Football Association which was the first Australian rules competition in Victoria, second in the country after the South Australian Football Association. The first games were played in 1897 between the foundation clubs – Carlton, Collingwood, Essendon, Fitzroy, Geelong, Melbourne, St Kilda and South Melbourne. Essendon won the first VFL premiership.
Although the Victorian Football League and the Victorian Football Association continued to compete for spectator interest for many years, the VFL quickly established itself as the premier competition in Victoria. In the early years Fitzroy and Collingwood were the dominant teams, but by the mid-1900s Carlton began a dominating period of three successive flags from 1906 to 1908. Essendon under Jack Worrall - the first great coach - won a most convincing victory in 1911 with ten straight wins and surprisingly defended their flag in 1912 after being erratic during the home-and-away rounds.
In 1908, Richmond and University joined the VFL. Richmond eventually succeeded after a slow start, but University, after three promising seasons, won only one of its last seventy matches and its already thin ranks were so depleted it disbanded at the end of 1914.
More information on how war affected the VFL see: The VFL during the World Wars.

Between the World Wars
Richmond won its first premierships in 1920 and 1921 but Essendon - battlers since their 1912 flag - took over as the dominant team between 1922 and 1926. In 1924 the VFL inaugurated the Brownlow Medal for the player who received the most votes from the umpires for the Best and Fairest player.
In 1925, Footscray (now the Western Bulldogs), Hawthorn and North Melbourne joined the VFL. Footscray adapted to the VFL relatively quickly and by 1928 were well off the bottom of the ladder. However, North Melbourne and Hawthorn remained "chopping blocks" for a very long period. North Melbourne were not to win more than eight games in a season until 1944 and Hawthorn only once won more than seven until 1954. Between them, Hawthorn and North Melbourne finished in last place fifteen of the twenty-nine years from their admittance until 1953 - by which time however North had become a powerful side and finished in the first two on the ladder in 1949 and 1950. In the later years of this period Hawthorn and St. Kilda finished last in all but two of the fifteen seasons between 1941 and 1955.
Between the years of 1927 and 1930, Collingwood FC became the first and so far, the only, team to win four successive premierships and finish a season without losing (or drawing) a game. This team became known as "the machine" because of the organised and consistent way it played. During this period of success Collingwood became the greatest club in the nation, possessing the largest and fiercest supporter base drawn originally from working class districts in inner Melbourne. With premiership victories in 1935 and 1936 the Collingwood Football Club had already won 11 premierships, and remained the most successful premiership club until Carlton began to lead the premiership tally in 1982.
In the 1930s, Richmond and South Melbourne rivaled Collingwood as the best team, with Richmond's brilliant defence destroying South's powerful attack in the 1934 Grand Final. Melbourne, which had won the premiership in 1926 but fallen off sharply, developed a powerful attacking side that swept all before it between 1939 and 1941 to win three successive flags; however Essendon, after years in the wilderness from 1927 to 1939, enjoyed a dominant period with nine grand final appearances between 1941 and 1951............

1950s
In 1952, the VFL hosted ‘National Day’, when all 6 matches were played outside of Melbourne. Matches were played at the Sydney Cricket Ground, Brisbane Exhibition Ground, North Hobart Oval, Albury Sports Ground and Victorian country towns Yallourn and Euroa.
In 1959, the VFL planned the first purpose built mega-stadium, Waverley Park, to give it some independence from the Melbourne Cricket Club which managed the Melbourne Cricket Ground, Australian rules' spiritual home. Waverley Park was planned to hold 167,000 spectators (thus making it one of the largest stadiums in the world). Land for the stadium was purchased at Mulgrave, in those days just farmland, but one day predicted to be near demographic centre of Melbourne's population.
Geelong was the stand out team at the beginning of the 1950s, winning the premiership in 1951 then setting a record of 23 consecutive wins starting in Round 12, 1952 and ending in Round 13, 1953. This streak included the 1952 premiership.
After Footscray won its first premiership in 1954 by defeating Melbourne, Melbourne became a powerhouse, winning five premierships between 1955 and 1960, including three in a row between 1955 and 1957. In 1958 Collingwood famously defeated Melbourne in the Grand Final, thereby preventing Melbourne from equalling Collingwood's record of four successive premierships.
Television coverage began in 1957, with direct telecasts of the final quarter permitted. At first, several channels competed through broadcasting different games. However, when the VFL found that television was reducing crowds, it decided that no coverage was to be allowed for 1960. In 1961, the modern system of replays was introduced and only very rarely have direct telecasts been permitted since.

1960s
In the 1960s, television began to have a huge impact, which continues unabated to this day. Spectators hurried home from games to watch replays and many former players took up positions as commentators on pre-game preview programs and post-game review programs. There were also several attempts at variety programs featuring VFL players, who generally succeeded in demonstrating that their skills were limited to the football ground.
The VFL played the first of a series of exhibition matches in 1962 in an effort to lift the international profile of the league.
Hawthorn won its first ever Grand Final in 1961, beating Footscray. Melbourne's period of success ended with its premiership win in 1964 over Collingwood, after which Carlton famously recruited Melbourne's champion player Ron Barassi as its captain-coach. St Kilda won its first Grand Final by one point over Collingwood in 1966, and after many years in the doldrums, Richmond won the Grand Final in 1967, starting a revival which lasted until the early 1980s. Under Barassi's leadership, Carlton won the premiership in 1968, its first since 1947. On the whole, though, Essendon and Geelong were the best teams during the 1960s, even though they only won three of the ten premierships.
With the number of players recruited from country leagues increasing, the wealthier clubs were gaining an advantage that metropolitan zoning and the Coulter law restricting player payments had prevented in the past. Country zoning was introduced in the late 1960s, and whilst it pushed Essendon and Geelong from the top of the ladder, it created severe inequality during the 1970s and 1980s. Only six teams made the grand final between 1972 and 1987, as against nine between 1961 and 1967.

1970s
1970 saw the opening of Waverley Park, with the inaugural match being played between Geelong and Fitzroy, on 18 April 1970. Construction work was carried out at the stadium as the 1970s progressed, culminating in the building of the now heritage listed Sir Kenneth Luke stand. The Queen of England, Elizabeth the second was a guest at the game and officially opened the stadium to the public.
The 1970 Grand Final between Carlton and Collingwood attracted a record crowd for a football game in Australia of 121,696. This game also saw the greatest comeback in Grand Final history when after trailing by 44 points at half time, Carlton managed to win by 10 points. Alex Jesaulenko took one of the most memorable marks in the sport's history during this game.
Hawthorn defeated St. Kilda in the Grand Final in 1971, beginning a long period of success that lasted into the early 1990s. The match was notable for Peter Hudson's famed attempt at breaking Bob Pratt's long held record of 150 goals in a season. Hudson kicked three goals in the match, equalling Pratt's season tally.
North Melbourne won its first ever premiership in 1975, then won again in 1977 in the Grand Final replay, following the second ever drawn Grand Final, against Collingwood. 1977 also saw the commencement of State of Origin representative matches, where players were only able to represent the state of their birth, as opposed to representing the state in which they were currently playing.
The 1979 VFL Grand Final is remembered for a controversial goal that sealed the Premiership for Carlton. After leading by 28 points during the second quarter, Collingwood had fallen behind by 21 points before mounting a late comeback. They were trailing by four points in the dying stages of the match when Carlton's Wayne Harmes miskicked, chased the ball towards the boundary line and knocked it to his team mate Ken Sheldon who kicked a goal to give Carlton a 10-point lead. Their eventual winning margin was just five points. Although Harmes won the inaugural Norm Smith Medal for the best player in the Grand Final, he is best-remembered for this incident as Collingwood supporters still claim that the ball had crossed the boundary line before Harmes knocked it to Sheldon.
Many rule changes were made during the decade in efforts to increase the attractiveness of the game:
A "final five" system was introduced in 1972. The Grand Final was the highest scoring Grand Final in history, accumulating a total of 327 points with Carlton defeating Richmond by 27 points.
The centre diamond and a limit of four players per team at the centre bounce were introduced in 1973. The diamond was changed to the square in 1975.
The two-umpire system was introduced in 1976.
In 1978 the interchange law was introduced, to allow players to be able to be interchanged at any time (like basketball), rather than a one-off replacement (as in soccer).

1980s - national expansion
At the time, there was no national league for Australian rules that incorporated interstate clubs. The VFL was the most popular and dominant league around the country in terms of overall attendance and interest and began expanding its influence into other states. In 1980, the match of the day was broadcast on television. Interest around the country followed, and new sides from other capitals (many with their own local leagues) soon expressed interest in new licences.
In 1982, South Melbourne relocated to Sydney to become the Sydney Swans. The West Australian Football League and Queensland Australian Football League were awarded licences to join the VFL and the West Coast Eagles and Brisbane Bears were formed. These expansion team licences were awarded on payment of multi-million dollar fees which were not required of the existing VFL clubs. The first National Draft was introduced in 1986. The West Coast Eagles and Brisbane Bears joined the league in 1987. The night premiership, the Panasonic Cup moved to the pre-season instead of mid-year.
In 1984, a revival of the International Rules representative series against Ireland occurred. In 1987, a salary cap was introduced. In 1988, the law changed to make players awarded free kicks be obliged to kick the ball, rather than handpass. This rule change was reversed in 1990.
Ross Oakley was appointed CEO of the VFL in 1986, and immediately set about plans for national expansion of the competition.
In 1989, the league began encouraging some of the fledgling Victorian clubs to merge or relocate interstate. Footscray and Fitzroy were almost forced into amalgamation, but a fundraising event from Footscray supporters stopped the proposed merger at the eleventh hour.
Collingwood played in its third successive Grand Final in 1981, yet didn't win any of them. This added to Collingwood's already infamous record in Grand Finals, signified by the term "the Colliwobbles" - after their Premiership triumph of 1958, Collingwood lost the next eight Grand Finals in which they played, often after seemingly having the match in their keeping. They also finished on top of the ladder twice after the regular season matches (in 1969 and 1973), only to experience a loss of form in the finals and miss the Grand Final altogether. "The Colliwobbles" was introduced after the 1970 Grand Final loss to Carlton.
A bitter rivalry between Essendon and Hawthorn emerged after competing in three consecutive Grand Finals between 1983 and 1985. Essendon's win in the 1984 marked the first time since 1966 that a team other than Richmond, Carlton, Hawthorn or North Melbourne had won the premiership. The dominance of these few clubs and mounting financial problems for several clubs resulted in the VFL adopting an equalisation policy, centred around the player draft and salary cap measures.
In 1988, Melbourne made its first appearance in a Grand Final since 1964, but it wasn't a memorable return to the big stage. Hawthorn crushed an underdog Melbourne side by 96 points, the then biggest Grand Final win in history, a record which stood until 2007.
In what many believe to be the finest VFL/AFL Grand Final of the modern era, Hawthorn overcame a strong challenge from Geelong in 1989. It was a physical game right from the start when Geelong's Mark Yeates ran through Dermott Brereton at the opening bounce, bruising Brereton's kidney and causing internal bleeding. In a courageous display, Brereton refused to leave the ground and marked and goaled several minutes later to stem Geelong's attempt to establish superiority. Later heavy clashes would see John Platten knocked out and Robert DiPierdomenico suffer broken ribs and a punctured lung. Despite a Grand Final record nine goals from Geelong's Gary Ablett, Hawthorn still went on to win by six points.

1990s - Australian Football League
To reflect the steps towards a national competition, the VFL was renamed as the Australian Football League in 1990. The VFL name disappeared until it was adopted by the AFL's state feeder competition which was the most recent incarnation of the former VFA.
Collingwood won the inaugural AFL premiership in 1990, ending a drought of near misses that had seen the club lose grand finals in 1960, 1964, 1966, 1970, 1977, 1979, 1980 and 1981. By 1990 Collingwood had played in 36 Grand Finals, just under 40% of all grand finals played.
1990 also saw the Port Adelaide Magpies make a bid for an AFL licence. In response, the SANFL formed a composite team called the Adelaide Crows which was awarded the licence and joined the league in 1991. That same year the Grand Final was played at Waverley Park for first and only time as the MCG underwent redevelopment. This game was also the first time that a non-Victorian team - West Coast Eagles - contested the Grand Final, only to be outclassed by a Hawthorn side coming to the end of their era of dominance.
With Adelaide bringing the number of teams to 15, the final six was introduced in 1991. In 1992, Waverley Park was renamed "AFL Park" and the West Coast Eagles became the first non-Victorian team to win a premiership, beating Geelong. 1992 was also the final year the Brisbane Bears called Carrara Stadium home, as they moved to the Brisbane Cricket Ground at Woolloongabba (commonly known as The 'Gabba) in time for the 1993 season.
In 1994, the Fremantle Football Club was formed to represent the strong history of Fremantle clubs from the WAFL, and played its first game in the AFL in 1995. That year, the first Western Derby was played between the two Perth-based teams, beginning a fierce local rivalry with West Coast dominating until Fremantle broke the shackles in their 10th meeting in 1999. Carlton made the record books by winning its 16th premiership after 16 consecutive wins and only two losses for the entire season.

Some of the rule changes of the decade included:
In 1994, a third field umpire was introduced.
In 1994, the McIntyre Final Eight System system was introduced.
A fourth interchange player was added for the 1998 season, increasing match day squads to 22 players.

In 1996, the VFL/AFL celebrated its centenary. One round of games featured a repeat of the games in Round 1, 1897, with players wearing replicas of the guernseys worn 100 years earlier. Late in the season, after it looked like the Fitzroy Lions would succumb to financial problems and merge with North Melbourne, the AFL dramatically announced that Fitzroy would merge with the Brisbane Bears and play as the Brisbane Lions from 1997[9]. North Melbourne recovered from being jilted, and became the only team to win the once-off gold premiership cup by defeating Sydney, which had not played in a Grand Final since 1945 (when they competed as South Melbourne).
Later in 1996, an attempt to merge Melbourne and Hawthorn to form the Melbourne Hawks made headlines, but failed to eventuate. Ross Oakley stepped down as the AFL's Chief Executive and was replaced by Wayne Jackson. The AFL also rejected bids from Queensland club Southport Sharks and the Tasmanian government to enter teams.
In 1997, the Port Adelaide Magpies were finally awarded a licence to join the AFL as the Port Adelaide Power, coinciding with the Fitzroy/Brisbane merger to keep the league a 16 team competition. The inaugural Showdown occurred in that year, with Port Adelaide causing an upset victory over Adelaide, who recovered from the shock and went on to win the first of two consecutive premierships and became the first side in history to win four finals in one series and win the premiership. St. Kilda, their opponent, were playing in their first Grand Final since 1971. The Footscray Bulldogs were renamed the Western Bulldogs, in order to reflect the club's representation of Melbourne's western suburbs. 1997 was a year in which the perennial underdogs prospered. St Kilda, the Western Bulldogs and Adelaide all shot up the ladder, renewing the spirits of their clubs, and the competition.
Adelaide repeated its feats of a year before to win the premiership (after losing their first finals match to Melbourne), beating favourites North Melbourne. North had major goal scoring problems in the match and had a dismal second half. Andrew McLeod won his second Norm Smith Medal in two years, and the Adelaide Crows became the first team since Richmond in 1921 to turn their maiden Premiership into a double the following season. The International Rules series against the Gaelic Athletic Association was rekindled in 1998, after the series was erased from the league fixtures following 1990. Wayne Carey skippered one of the league's finest teams, including Nathan Buckley, Robert Harvey, Matthew Lloyd and Mark Ricciuto.
In 1999, the league sold Waverley Park stadium and used the funds in a joint venture to begin construction of a brand-new stadium situated at Melbourne's Docklands. The league announced the last AFL State of Origin match (with Victoria thumping South Australia on a wet day at the MCG), its intentions to instead to focus on the new national league. Finishing in sixth place at the end of the regular season, Carlton fought hard in the finals and recorded a remarkable one-point upset victory in the Preliminary Final against Essendon. In what was the final Grand Final of the 20th century, the Blues lined up against North Melbourne who the same year had renamed themselves as the "Kangaroos" in order to appeal to a national audience. A competitive game up to half time, the Roos, with thanks to Norm Smith Medallist Shannon Grant, ran away with the game and the premiership by 35 points.

2000s
The AFL logo was again changed in 2000, with a new look for the new millennium. The competition's two most bitter rivals, Collingwood and Carlton, signed off on the 1900s with the 'Millennium Match', played at the MCG on New Years Eve. As a spectacle, the runners up in the previous season's Grand Final flogged the 16th placed Magpies, with Brendan Fevola supplying Blues fans with a taste of things to come, booting 12 goals. The first indoor AFL match was held at Docklands Stadium, now Telstra Dome, in round one of 2000. In the first game at the new venue, Essendon crushed Port Adelaide by 94 points. It was a sign of things to come, as Essendon lost only one match for the entire season equaling Collingwood's team of 1929 (dubbed "The Machine"), and one of the highest percentages at 159.1%. They faced Melbourne in the Grand Final and belted them by 60 points. Skipper James Hird was awarded the Norm Smith Medal, capping off a fine season following three successive injury plagued campaigns; Matthew Lloyd took out the Coleman Medal after breaking the 100 goal barrier for the first time in his career, and Melbourne's previously unheralded Shane Woewodin was a surprise winner of the Brownlow Medal.
Season 2001 was the first of several seasons of dominance by the non-Victorian teams. The Brisbane Lions won the first of their historic three successive premierships, becoming the first team north of the Murray River to win a premiership, and non-Victorian team to win more than two on the trot. The changing of the guard from Essendon's dominance took place in a famed clash at the Gabba in round 10 with the Lions overcoming Kevin Sheedy's men by 28 points. It was the first of the Lions record 19 victories in succession. Port Adelaide, Hawthorn and Richmond all made significant inroads in 2001, the Hawks falling short by a mere nine points against Essendon in the Preliminary Final, Trent Croad's shot for goal in the dying minutes looked destined to put the Hawks into the decider, before it swung into the goalpost. Paul Barnard sealed the win, albeit an unconvincing one, with several Bombers heading into the Grand Final seven days later under injury clouds. After a closely contested first half, Brisbane streaked away in the third term to record a 26 point victory in the Grand Final, sparking jubilation from fans of Fitzroy and Brisbane Bears, who were finally brought together in arguably the spiritual completion of the 1996 merger. Rover Shaun Hart was awarded the Norm Smith Medal, Lion maverick Jason Akermanis took home the Brownlow Medal, whilst Lloyd was again the John Coleman Medallist, once more notching up his ton in the Qualifying Final, on this occasion against Richmond at the MCG. The season was also notable as it was the 45th and final season of the television broadcast rights remaining in the hands of Channel Seven, with Channels 9, 10 and pay-TV operator Foxtel granted the rights for 2002-2006.
The 2002 season was one of the closest on record, with a change in the status quo taking place. Hawthorn and Richmond both missed out on their share in the September action, and Collingwood finally emerged from a seven year exile from finals action. Carlton, too, suffered from winds of change, winning the first Wooden Spoon in the club's history, a season which terminated the coaching career of Wayne Brittain, John Elliot's ruling as president, and paved the way for Denis Pagan to leave the Kangaroos for Optus Oval. Brisbane, however, were at the peak of their powers, and along with Port Adelaide vied for top spot on the league table for much of the season, a battle resolved in the final round at AAMI Stadium, when Power onballer Roger James snapped the match winning goal with a minute remaining. The season began in a media frenzy, with North Melbourne captain, and arguably the greatest footballer of the 1990s, Wayne Carey, quitting the Kangaroos after an off field uproar. In the face of adversity, the Roos stuck tight, and the famed Shinboner Spirit continued to prosper, as veterans Anthony Stevens, Glenn Archer and David King helped propel their side back into the September action, only to have their year cut short by Melbourne in the Elimination Final, marking the end of John Blakey's career as a player, and Pagan's 10 year tenure at Arden Street. The brave young Magpies began the season in strong form, before striking an end of season slump, which saw them win only one of their final four matches of the premiership season. The form table was swung dramatically in the first week of the finals, as they shell-shocked Port Adelaide in foreign territory in South Australia in the Qualifying Final. The Magpies were superb early, and held off a late Power surge to secure a home Preliminary Final. The win was achieved sans hamstrung skipper Nathan Buckley, with Paul Licuria admirably filling his sizeable breach with a heroic 40 disposals. The Magpies had an unfortunate setback though, when courageous debutant Jason Cloke was suspended for two matches for a clumsy yet honest strike on Crow Tyson Edwards. He was to miss the biggest day of the year, in a cruel twist of fate for a youngster who had not missed a match since his debut in round two against the Eagles. The Grand Final was an absorbing contest from start to finish, with Brisbane finishing the day only nine points ahead of Collingwood on a sodden, overcast day. The final margin was the largest of the entire match, making it one of the closest Grand Finals in history. It was the little known Magpie second tier which caught the Lions off guard early, the experienced bodies of Glenn Freeborn, Rupert Betheras and Steve McKee, combined with the strong tackling of Scott Burns unsettling the normally unflappable Lions. Not to be outdone, Brisbane ruckman Clark Keating rose to the fore following an injury to teammate Beau McDonald, controlling the centre bounces, while Nigel Lappin and Alistair Lynch threatened all afternoon. However, the biggest battle was left to the two biggest names, opposing skippers Nathan Buckley and Michael Voss slugging it out for not only the Norm Smith Medal, but the flag itself. Although Buckley finished the day with the Norm Smith dangling around his neck, it was Voss who held the "Holy Grail" aloft at the days end.
Season 2003 was, to an extent, a continuation of the previous season, in terms of form, however it was also a year of transition, when Andrew Demetriou was appointed as Chief Executive Officer of the league, with Wayne Jackson (1997-2003) stepping down from his role. The season saw one highly emotional moment on 6 June, when Jason McCartney returned to play for North Melbourne after suffering life-threatening burns in the 2002 Bali bombing; he retired immediately after the game was won against Richmond. The status quo remained at the top of the ladder, with Collingwood acting as the premiership favourite for much of the season, whilst Port Adelaide and Brisbane were snapping at their heels. At season's end, all six non-Victorian teams filled positions in the top eight, Collingwood (2nd) and Essendon (8th) the only teams from the "homeland" to keep a foothold in the helter-skelter of league football. The Magpies overcame their bogey side, the Lions, in a tense Qualifying Final, with thanks to Alan Didak's magical left foot goals late in the last quarter. Earning a two week break, the Magpies steamrolled the Power in the Preliminary Final to the tune of 44-points to book their second Grand Final in as many seasons, which was played against, once again, Brisbane. The Lions, after their defeat at the hands of the Magpies in the first week of the finals series, were forced to take the long road home, accounting for Adelaide on home soil before overrunning the Swans at Telstra Stadium. Sydney had earned their home Preliminary Final with their shock victory over Port Adelaide at AAMI Stadium in the First Preliminary Final, a victory which ensured that the Power had much work to do to do away with their take as 'chokers'. Despite going in as favourites, and equipped with Brownlow Medallist Nathan Buckley, who shared it with Adelaide's Mark Ricciuto and Sydney's Adam Goodes, the Magpies Grand Final preparations were turned upside down by the suspension of their centre half forward, Anthony Rocca, who was booked and suspended for two weeks for striking Port's Brendon Lade the week prior. Collingwood appeared to be all at sea on the biggest day of the year, in contrast to their efforts of the previous title tilt, the experienced Brisbane flogged the Magpies, winning their third consecutive premiership by 50-points, a win highlighted by a Grand Final record 39 disposals from Simon Black, and five incredible goals from livewire Jason Akermanis. Brisbane became the first team since Melbourne in the 1950s to win three consecutive premierships.
The 2004 season was another dominated by the non-Victorian teams, so much so that it was the first Grand final in history not contested by a Victorian team. The Brisbane Lions were out to get their fourth consecutive premiership, however it was Port Adelaide that took home the cup. The Power overran the tiring Brisbane outfit ending its reign as kings of the AFL jungle.
2005 saw a very defensive style of play dominate and the longest premiership drought in history broken. It was the first time in 72 years, and the first time since the relocated from South Melbourne, that Sydney Swans took home the cup. In a tightly fought contest from start to finish, Sydney defeated the West Coast Eagles by four points, one of the lowest scoring Grand Finals in history and the closest final scores since 1966, made possible by a memorable mark from Swan's defender Leo Barry in the dying seconds that halted a late charge by the Eagles.
In 2006 there was the so-called Sirengate scandal, when the umpires failed to hear the final siren in the match between Fremantle and St.Kilda at Aurora Stadium, Launceston. Before the on-field officials could be notified that the game should have ended, St.Kilda scored a behind to level the scores and force a draw. In the days that followed, Fremantle appealed and were awarded the game and full competition points. A series of new rule changes were introduced for the 2006 season intended to speed up the game, including allowing the ball to be brought back into play immediately after a point is scored (instead of waiting for goal umpires to wave their flag) and limiting the time allowed for players with a mark to kick for goal to 30 seconds. The Swans and Eagles had built a close rivalry with the Eagles beating the Swans during the season by only four points. In the first Qualifying final, Sydney took their revenge by earning a weeks rest by only one point. The Grand Final was another carbon copy, with the Swans and Eagles facing off again in the decider. This time it was the West Coast Eagles who triumphed by one point, exacting revenge on the Sydney Swans also for the 2005 Grand Final defeat.
In 2007, the Geelong Cats had one of the most dominating seasons in the competition's history. After finishing the home and away season three games clear in first place, winning 19 of the last 20 matches including 15 in a row, having a record nine All-Australian players and winning most of the individual awards including the Brownlow Medal, AFL Rising Star, Leigh Matthews Trophy and the J. J. Liston Trophy (VFL B&F), they competed the finals series with only one close match. After doing away with an unexpected Kangaroos outfit in the first week, whom had been plagued with board instability and pressure to relocate to the Gold Coast, the Cats faced up against Collingwood two weeks later in the preliminary for a close fought match. The Magpie made it only by beating the Eagles in Perth the week before in extra time. The Grand Final then saw Geelong end their 44 year premiership drought with a record breaking 119 point victory over Port Adelaide with Steve Johnson winning the Norm Smith Medal.

UEFA European Football Championship

The UEFA European Football Championship is the main football competition of the men's national football teams governed by the UEFA. Held every four years since 1960, in the even-numbered year between World Cup tournaments, it was originally called the European Nations Cup, changing to the name European Football Championship in 1968. Specific championships are often referred to in the form "Euro 2008" or whichever year is appropriate.

There is a UEFA Women's Championship inaugurated in 1984 and from 1997 held every four years, as well as a Men's Under-21 equivalent of the UEFA European Championship tournament, taking place every two years.

History

The first idea for a pan-European football tournament was proposed by the French Football Federation's Henri Delaunay in 1927, however it was not until 1958 that the tournament was started. In honour of Delaunay, the trophy awarded to the champions is named after him. The 1960 Tournament, held in France, had 4 teams competing in the finals, out of 17 that entered the competition. It was won by the Soviet Union, beating Yugoslavia 2-1 in a tense final in Paris. Spain withdrew from its quarter-final match against the USSR due to political protests. Of 17 teams that entered the qualifying tournament, notable were absentees West Germany and Italy. Spain held the next tournament, in 1964 which saw an increase in entries to the qualification tournament, with 29 entering; however, Greece withdrew after being drawn against Albania, whom they were still at war with. The hosts beat the holders the Soviet Union 2-1 at the Santiago Bernabéu in Madrid.

The tournament format stayed the same for the 1968 edition. Italy were the hosts and champions: for the first and only time a match was decided on coin toss (the semi-final against the Soviet Union) and the final went to replay, after the match against Yugoslavia finished 1-1. Italy won the replay 2-0. More teams entered this tournament (31), a testament to its burgeoning popularity. Belgium held the 1972 edition, which West Germany won, beating the USSR 3-0 in the final in Brussels, this tournament would provide a taste for things to come, as the German side contained many of the key members of the 1974 FIFA World Cup Champions. The 1976 tournament would be the last in which only four teams took part in the final tournament, and the last in which the hosts had to qualify themselves, Czechoslovakia beat Germany in the newly introduced penalty shootout, with Antonín Panenka's famous chipped shot.

Eight teams took part in the next tournament hosted by Italy. It involved a group stage, with the winners of the groups going on to contest the final, and the runners-up playing in the third place play-off. West Germany won their second European title by beating Belgium 2-1 at the Stadio Olimpico in Rome. France won their first major title at home in the 1984 tournament, with their captain Michel Platini scoring an amazing 9 goals in just 5 games, including the opening goal in the final, in which they beat Spain 2-0. The format changed also, with the top two in each group going through to a semi-final stage, instead of the winners of each group going straight into the final. The third place play-off was also abolished.

In Euro 88 held in West Germany, the Netherlands pulled off one the the greatest moments in their sporting history, when they beat the hosts (traditional rivals) 2-1 in the semi-finals, which sparked vigorous celebrations back home. The Netherlands went on to win the tournament, beating the USSR 2-0 at the Olympia Stadion in Munich, a match in which Marco Van Basten scored one of the most memorable goals in football history, a spectacular volley over the keeper from the right wing. UEFA Euro 1992 was held in Sweden, and was won by Denmark, in one of the most surprising outcomes ever. Denmark were only in the tournament because of the withdrawal of Yugoslavia due to the wars of yugoslav secession. However, they produced a shock, beating World Champions Germany 2-0, having beaten holders the Netherlands on penalties in the semi-finals. This was the first tournament in which a unified Germany took part and also the first major tournament to have the players' names printed on their backs.

Euro 96, held in England, would see the number of teams taking part double to 16. The hosts, in a replay of the 1990 FIFA World Cup semi-final, were knocked out on penalties by Germany, who would go on to win in the final 2-1 against the newly born Czech Republic thanks to the first golden goal ever in a major tournament, scored by Oliver Bierhoff. This was Germany's first title as a unified nation. Euro 2000 was the first tournament to be held by two countries, Netherlands and Belgium. France (reigning World Champions) were favourites to win, they lived up to expectations when they beat Italy 2-1 after extra time, in an amazing come back from 1-0 down: Sylvain Wiltord equalised on the very last minute of the game and David Trezeguet scored the winner in extra time. Like in Euro 92, Euro 2004 produced an upset no one could predict. Greece, who had only qualified for one World Cup (1994) and one European championship (1980) before, beat the hosts Portugal 1-0 in a dramatic final (after having beaten them also in the opening game) to win a tournament that they had been given odds of 150-1 to win before it began. On their way to the final they also managed to beat holders France as well as dark horses the Czech Republic with a silver goal, a rule which replaced the previous golden goal in 2003 before being abolished itself shortly after this tournament.

Trophy

The Henri Delaunay Trophy, which is awarded to the winner of the European Football Championship, is named in honor of Henri Delaunay, the first General Secretary of UEFA, who came up with the idea of a European championship but died five years prior to the first tournament in 1960. His son Pierre Delaunay was the person in charge of making the trophy. Since the first tournament it has been awarded for the winning team to keep for four years, until the next tournament.

For the 2008 tournament, the trophy was slightly remodelled making it larger. The trophy, which is made of sterling silver, now weighs 8 kilograms and is 60 centimeters tall. A small figure juggling a ball on the back of the original was removed, as was the marble plinth. The silver base of the trophy had to be enlarged to make it stable. The names of the winning countries that had appeared on the plinth have now been engraved on the back of the trophy.

The competition

Before 1980, only four teams qualified for the final tournament. From 1980 eight teams competed and in 1996 the tournament expanded again to the current number of teams, 16. The competing teams are chosen by a series of qualifying games: in 1960 and 1964 through home and away play-offs; from 1968 through a combination of both qualifying groups and play-off games. The host country was selected from the four finalists after they were determined through qualifying.

Since the expansion of the final tournament starting from 1980, the host country, or countries, have been chosen beforehand and qualify automatically.

The defending champions have never been granted an automatic place in the finals.

Qualifying

In order to qualify a team must be winners or runners-up in one of the seven qualifying groups. After this a team proceeds to the finals round in the host country, although hosts qualify for the tournament automatically. The qualifying phase begins in the autumn after the preceding FIFA World Cup, almost two years before the finals.

The groups for qualification are drawn by a UEFA committee using seeding. Seeded teams include reigning champions, and other teams on the basis of their performance in the preceding FIFA World Cup qualifying and the last European Football Championship qualifying. To obtain an accurate view of the teams abilities, a ranking is produced. This is calculated by taking the total number of points won by a particular team and dividing it by the number of games played, i.e., points per game. In the case of a team having hosted one of the two previous competitions and therefore having qualified automatically, only the results from the single most recent qualifying competition are used. If two teams have equal points per game, the committee then bases their positions in the rankings on:

  1. Coefficient from the matches played in its most recent qualifying competition.
  2. Average goal difference.
  3. Average number of goals scored.
  4. Average number of away goals scored.
  5. Drawing of lots.

The qualifying phase is played in a group format, the composition of the groups is determined through means of a draw of teams from pre-defined seeded bowls. The draw takes place after the preceding World Cup's qualifying competition. For the 2008 European Football Championship, the group qualifying phase consists of seven groups; one of eight teams and the remainder of seven teams each.

The qualifying phase is done in groups, each effectively a mini league, where the highest ranked team and the runner up, after all the teams have played each other home and away, progresses to the finals tournament. As with most leagues, the points are awarded as three for a win, one for a draw, and none for a loss. In the eventuality of one or more teams having equal points after all matches have been played, the following criteria are used to distinguish the sides:

  1. Higher number of points obtained in the group matches played among the teams in question.
  2. Superior goal difference from the group matches played among the teams in question.
  3. Higher number of goals scored in the group matches played among the teams in question.
  4. Higher number of goals scored away from home in the group matches played among the teams in question.
  5. Results of all group matches:
    1. Superior goal difference
    2. Higher number of goals scored
    3. Higher number of goals scored away from home
    4. Fair play conduct.
  6. Drawing of lots.

Final tournament

Sixteen teams progress to the final tournament; for the 2008 tournament, they will be the winners and runners up of the seven qualifying groups and joint hosts Austria and Switzerland. These sixteen teams are divided equally into four groups, A, B, C and D, each consisting of four teams. The groups are drawn up by the UEFA administration, again using seeding. The seeded teams being the host nations, the reigning champions, subject to qualification, and those with the best points per game coefficients over the qualifying phase of the tournament and the previous World Cup qualifying. Other finalists will be assigned to by means of a draw, using coefficients as a basis.

The four groups are again played in a league format, where a team plays its opponents once each. The same points system is used (three points for a win, one point for a draw, no points for a defeat). A schedule for the group matches will be drawn up, but the last two matches in a group must kick off simultaneously. The winner and runner-up of each group progresses to the quarter-finals, where a knockout system is used (the two teams play each other once, the winner progresses), this is used in all subsequent rounds as well. The winners of the quarter-finals matches progress to the semi-finals, where the winners play in the final. If in any of the knockout rounds after normal playing time, the scores are still equal, extra time and penalties are employed to separate the two teams.





Asian Football Confederation (AFC)

The 46 member Asian Football Confederation (AFC) is the governing body of football in Asia, excluding Cyprus and Israel but including Australia. It was founded in 1954 in Manila, Philippines, and is one of FIFA's six Continental Confederations. (Nations with some European and some Asian territory, such as Turkey, Kazakhstan, Azerbaijan, Armenia, Georgia, and Russia, are instead covered by UEFA; Israel, which lies entirely in Asia, is also a UEFA member.) The main headquarters is located in Bukit Jalil, Kuala Lumpur, Malaysia. The current president is Mohammed Bin Hammam of Qatar.

Former AFC secretary general Teoh Chye Hin, who headed the AFC from 1974 until 1978, died in April 2008.

AFC competitions

The AFC runs the Asian Cup, a competition for the national football teams of Asia held every four years, as well as the Asian World Cup Qualifying Tournament and the AFC Challenge Cup. It also runs the Asian Olympics Qualifying Tournament. The AFC also runs three levels of annual international club competitions. The most prestigious (and oldest of the current AFC club competitions) is the AFC Champions League tournament, based on the UEFA Champions League, formed in 2002/03 with the amalgamation of the Asian Champions Cup and the Asian Cup Winners Cup. (An Asian Super Cup competition between the winners of these two major tournaments ended with the birth of the AFC Champions League.) The other competitions branched off this in 2004 when the 'Vision Asia' blueprint for development was launched. This led to the top fourteen AFC nations, the 'mature nations', sending their best teams to the AFC Champions League. The next 14 nations, the 'developing nations' qualify to send their teams to the AFC Cup.

The rest of the AFC-affiliated countries, the 'emerging nations' send their teams to the AFC President's Cup. The teams which qualify from each country are usually the champions and the cup winners. Currently there is no promotion and relegation between the different levels of nations.

The AFC is going to revamp 22 leagues in Asia, 10 of them by 2009-2012. This is due to the poor performance / absence of Asian teams in the 2006 World Cup. The reforms include: increasing transparency, increase competitiveness, improving training facilities and forcing the leagues to have a system of relegation and promotion.

The 10 leagues marked for reform are: Australia, Japan, China, South Korea, Singapore, India, Iran, United Arab Emirates, Saudi Arabia and Qatar. The proposal would mark a radical change in Australia, where professional leagues in all sports are organised on a model of franchised teams and closed league membership, a system most commonly identified with North America.

There are 12 AFC Nations that play in the UAFA organised Arab Nations Cup. These nations are Bahrain, Iraq, Jordan, Kuwait, Lebanon, Qatar, Oman, Palestine, Saudi Arabia, Syria, United Arab Emirates and Yemen.

Foot Ball

Football is the name given to a number of different team sports, all of which involve (to varying degrees) kicking a ball with the foot in an attempt to score a goal. The most popular of these sports world-wide is association football, also known as soccer and most commonly just football. The English language word "football" is also applied to gridiron football (which includes American football and Canadian football), Australian rules football, Gaelic football, rugby football (rugby league and rugby union), and related games. Each of these codes (specific sets of rules, or the games defined by them) is referred to as "football".

These games involve:

  • two teams of between 11 and 18 players
  • kicking a spherical or prolate spheroid ball (which is itself called a football) with the foot;
  • a clearly defined area in which to keep the ball;
  • scoring goals and/or points, by moving the ball to an opposing team's end of the field and either into a goal area, or over a line;
  • the goal and/or line being defended by the opposing team;
  • players being required to move the ball—depending on the code—by kicking, carrying and/or hand passing the ball;
  • goals and/or points resulting from players putting the ball between two goalposts and;
  • penalties imposed for causing the ball to leave the area of play, or excessive contact with the opposing team.

In most codes, there are rules restricting the movement of players offside and players scoring a goal must put the ball either under or over a crossbar between the goalposts. Other features common to several football codes include: points being mostly scored by players carrying the ball across the goal line and; players receiving a free kick after they take a mark/make a fair catch.

Peoples from around the world have played games which involved kicking and/or carrying a ball, since ancient times. However, most of the modern codes of football have their origins in Europe.

Etymology

While it is widely believed that the word "football" (or "foot ball") originated in reference to the action of a foot kicking a ball, there is a rival explanation, which has it that football originally referred to a variety of games in medieval Europe, which were played on foot. These games were usually played by peasants, as opposed to the horse-riding sports often played by aristocrats. While there is no conclusive evidence for this explanation, the word football has always implied a variety of games played on foot, not just those that involved kicking a ball. In some cases, the word football has even been applied to games which have specifically outlawed kicking the ball.

History

Ancient games

Documented evidence of what is possibly the oldest activity resembling football can be found in a Chinese military manual written during the Warring States Period in about the 476 BC–221 BC. It describes a practice known as cuju (蹴鞠, literally "kick ball"), which originally involved kicking a leather ball through a hole in a piece of silk cloth strung between two 30-foot (9.1 m) poles. During the Han Dynasty (206 BC–220 AD), cuju games were standardized and rules were established. Variations of this game later spread to Japan and Korea, known as kemari and chuk-guk respectively. By the Chinese Tang Dynasty (618–907), the feather-stuffed ball was replaced by an air-filled ball and cuju games had become professionalized, with many players making a living playing cuju. Also, two different types of goal posts emerged: One was made by setting up posts with a net between them and the other consisted of just one goal post in the middle of the field.

The Japanese version of cuju is kemari , and was adopted during the Asuka period from the Chinese. This is known to have been played within the Japanese imperial court in Kyoto from about 600 AD. In kemari several people stand in a circle and kick a ball to each other, trying not to let the ball drop to the ground (much like keepie uppie). The game appears to have died out sometime before the mid-19th century. It was revived in 1903 and is now played at a number of festivals.

The Ancient Greeks and Romans are known to have played many ball games some of which involved the use of the feet. The Roman writer Cicero describes the case of a man who was killed whilst having a shave when a ball was kicked into a barber's shop. The Roman game harpastum is believed to have been adapted from a team game known as "επισκυρος" (episkyros) or phaininda that is mentioned by Greek playwright, Antiphanes (388–311 BC) and later referred to by Clement of Alexandria. These games appears to have resembled rugby.

There are a number of references to traditional, ancient, and/or prehistoric ball games, played by indigenous peoples in many different parts of the world. For example, in 1586, men from a ship commanded by an English explorer named John Davis, went ashore to play a form of football with Inuit (Eskimo) people in Greenland.[3] There are later accounts of an Inuit game played on ice, called Aqsaqtuk. Each match began with two teams facing each other in parallel lines, before attempting to kick the ball through each other team's line and then at a goal. In 1610, William Strachey of the Jamestown settlement, Virginia recorded a game played by Native Americans, called Pahsaheman. In Victoria, Australia, indigenous people played a game called Marn Grook ("ball game"). An 1878 book by Robert Brough-Smyth, The Aborigines of Victoria, quotes a man called Richard Thomas as saying, in about 1841, that he had witnessed Aboriginal people playing the game: "Mr Thomas describes how the foremost player will drop kick a ball made from the skin of a possum and how other players leap into the air in order to catch it." It is widely believed that Marn Grook had an influence on the development of Australian rules football (see below).

Games played in Central America with rubber balls by indigenous peoples are also well-documented as existing since before this time, but these had more similarities to basketball or volleyball, and since their influence on modern football games is minimal, most do not class them as football.

These games and others may well go far back into antiquity and may have influenced later football games. However, the main sources of modern football codes appear to lie in western Europe, especially the British Isles.

Medieval and early modern Europe

The Middle Ages saw a huge rise in popularity of annual Shrovetide football matches throughout Europe, particularly in England. The game played in England at this time may have arrived with the Roman occupation, but there is little evidence to indicate this. Reports of a game played in Brittany, Normandy, and Picardy, known as La Soule or Choule, suggest that some of these football games could have arrived in England as a result of the Norman Conquest.

An illustration of so-called "mob football".

These forms of football, sometimes referred to as "mob football", would be played between neighbouring towns and villages, involving an unlimited number of players on opposing teams, who would clash in a heaving mass of people, struggling to move an item such as an inflated pig's bladder, to particular geographical points, such as their opponents' church. Shrovetide games have survived into the modern era in a number of English towns (see below).

The first detailed description of football in England was given by William FitzStephen in about 1174–1183. He described the activities of London youths during the annual festival of Shrove Tuesday:

After lunch all the youth of the city go out into the fields to take part in a ball game. The students of each school have their own ball; the workers from each city craft are also carrying their balls. Older citizens, fathers, and wealthy citizens come on horseback to watch their juniors competing, and to relive their own youth vicariously: you can see their inner passions aroused as they watch the action and get caught up in the fun being had by the carefree adolescents.

Most of the very early references to the game speak simply of "ball play" or "playing at ball". This reinforces the idea that the games played at the time did not necessarily involve a ball being kicked.

In 1314, Nicholas de Farndone, Lord Mayor of the City of London issued a decree banning football in the French used by the English upper classes at the time. A translation reads: "[f]orasmuch as there is great noise in the city caused by hustling over large foot balls [rageries de grosses pelotes de pee] in the fields of the public from which many evils might arise which God forbid: we command and forbid on behalf of the king, on pain of imprisonment, such game to be used in the city in the future." This is the earliest reference to football.

The earliest mention of a ball game that involves kicking was in 1321, in Shouldham, Norfolk: "[d]uring the game at ball as he kicked the ball, a lay friend of his... ran against him and wounded himself".

In 1363, King Edward III of England issued a proclamation banning "...handball, football, or hockey; coursing and cock-fighting, or other such idle games", showing that "football" — whatever its exact form in this case — was being differentiated from games involving other parts of the body, such as handball.

King Henry IV of England also presented one of the earliest documented uses of the English word "football", in 1409, when he issued a proclamation forbidding the levying of money for "foteball".

There is also an account in Latin from the end of the 15th century of football being played at Cawston, Nottinghamshire. This is the first description of a "kicking game" and the first description of dribbling: "[t]he game at which they had met for common recreation is called by some the foot-ball game. It is one in which young men, in country sport, propel a huge ball not by throwing it into the air but by striking it and rolling it along the ground, and that not with their hands but with their feet... kicking in opposite directions" The chronicler gives the earliest reference to a football field, stating that: "[t]he boundaries have been marked and the game had started.

Other firsts in the mediæval and early modern eras:

  • "a football", in the sense of a ball rather than a game, was first mentioned in 1486. This reference is in Dame Juliana Berners' Book of St Albans. It states: "a certain rounde instrument to play with ...it is an instrument for the foote and then it is calde in Latyn 'pila pedalis', a fotebal."
  • a pair of football boots was ordered by King Henry VIII of England in 1526.
  • women playing a form of football was in 1580, when Sir Philip Sidney described it in one of his poems: "[a] tyme there is for all, my mother often sayes, When she, with skirts tuckt very hy, with girles at football playes."
  • the first references to goals are in the late 16th and early 17th centuries. In 1584 and 1602 respectively, John Norden and Richard Carew referred to "goals" in Cornish hurling. Carew described how goals were made: "they pitch two bushes in the ground, some eight or ten foote asunder; and directly against them, ten or twelue [twelve] score off, other twayne in like distance, which they terme their Goales". He is also the first to describe goalkeepers and passing of the ball between players.
  • the first direct reference to scoring a goal is in John Day's play The Blind Beggar of Bethnal Green (performed circa 1600; published 1659): "I'll play a gole at camp-ball" (an extremely violent variety of football, which was popular in East Anglia). Similarly in a poem in 1613, Michael Drayton refers to "when the Ball to throw, And drive it to the Gole, in squadrons forth they goe".

Calcio Fiorentino

An illustration of the Calcio Fiorentino field and starting positions, from a 1688 book by Pietro di Lorenzo Bini.

In the 16th century, the city of Florence celebrated the period between Epiphany and Lent by playing a game which today is known as "calcio storico" ("historic kickball") in the Piazza della Novere or the Piazza Santa Croce. The young aristocrats of the city would dress up in fine silk costumes and embroil themselves in a violent form of football. For example, calcio players could punch, shoulder charge, and kick opponents. Blows below the belt were allowed. The game is said to have originated as a military training exercise. In 1580, Count Giovanni de' Bardi di Vernio wrote Discorso sopra 'l giuoco del Calcio Fiorentino. This is sometimes said to be the earliest code of rules for any football game. The game was not played after January 1739 (until it was revived in May 1930).

Official disapproval and attempts to ban football

Numerous attempts have been made to ban football games, particularly the most rowdy and disruptive forms. This was especially the case in England and in other parts of Europe, during the Middle Ages and early modern period. Between 1324 and 1667, football was banned in England alone by more than 30 royal and local laws. The need to repeatedly proclaim such laws demonstrated the difficulty in enforcing bans on popular games. King Edward II was so troubled by the unruliness of football in London that on April 13, 1314 he issued a proclamation banning it: "Forasmuch as there is great noise in the city caused by hustling over large balls from which many evils may arise which God forbid; we command and forbid, on behalf of the King, on pain of imprisonment, such game to be used in the city in the future."

The reasons for the ban by Edward III, on June 12, 1349, were explicit: football and other recreations distracted the populace from practicing archery, which was necessary for war.

By 1608, the local authorities in Manchester were complaining that: "With the ffotebale...[there] hath beene greate disorder in our towne of Manchester we are told, and glasse windowes broken yearlye and spoyled by a companie of lewd and disordered persons ..." That same year, the word "football" was used disapprovingly by William Shakespeare. Shakespeare's play King Lear contains the line: "Nor tripped neither, you base football player" (Act I, Scene 4). Shakespeare also mentions the game in A Comedy of Errors (Act II, Scene 1):

Am I so round with you as you with me,

That like a football you do spurn me thus?

You spurn me hence, and he will spurn me hither:

If I last in this service, you must case me in leather.

"Spurn" literally means to kick away, thus implying that the game involved kicking a ball between players.

King James I of England's Book of Sports (1618) however, instructs Christians to play at football every Sunday afternoon after worship. The book's aim appears to be an attempt to offset the strictness of the Puritans regarding the keeping of the Sabbath.

Mount Everest

Mount Everest, also called Chomolungma, Qomolangma or Zhumulangma (in Tibetan: ཇོ་མོ་གླང་མ, in Chinese: 珠穆朗玛峰 Zhūmùlǎngmǎ Fēng) or Sagarmatha (Nepali: सगरमाथा) is the highest mountain on Earth, as measured by the height of its summit above sea level, which is 8,848 metres or 29,029 feet. The mountain, which is part of the Himalaya range in High Asia, is located on the border between Sagarmatha Zone, Nepal and China.

The Great Trigonometric Survey of India established the first published height of Everest in 1856 at 29,002 ft (8,840 m), although at the time Everest was known as Peak XV. The mountain was given its official English name in 1865 by the Royal Geographical Society upon recommendation of Andrew Waugh, the British Survey General of India at the time. Waugh was unable to propose an established local name due to Nepal and Tibet being closed to foreigners at the time although Chomolungma had been in common use by Tibetans for centuries.

By the end of the 2007 climbing season, there had been 3,679 ascents to the summit by 2,436 individuals. There have been 210 deaths on the mountain, where conditions are so difficult that most corpses have been left where they fell; some are visible from standard climbing routes. Climbers range from experienced mountaineers to relative novices who count on their paid guides to get them to the top. This means climbers are a significant source of tourist revenue for Nepal, whose government also requires all prospective climbers to obtain an expensive permit, costing up to $25,000 (USD) per person.

Geology

Geologists have subdivided the rocks comprising Mount Everest into three units called “formations”. Each of these formations are separated from each other by low-angle faults, called “detachments”, along which they have been thrust over each other. From the summit of Mount Everest to its base these rock units are the Qomolangma Formation, the North Col Formation, and the Rongbuk Formation.

From its summit to the top of the Yellow Band, about 8,600 m above sea level, the top of Mount Everest consists of the Qomolangma Formation, which has also been designated as either the Everest Formation or Jolmo Lungama Formation. It consists of grayish to dark gray or white, parallel laminated and bedded limestone interlayered with subordinate beds of recrystallized dolomite with argillaceous laminae and siltstone. Gansser reported finding visible fragments of crinoids in these limestones. Petrographic analysis of samples of this Ordovician limestone from near the summit revealed them to be composed of carbonate pellets and finely fragmented remains of trilobites, crinoids, and ostracods. Other samples were so badly sheared and recrystallized that their original constituents could not be determined. The Qomolangma Formation is broken up by several high-angle faults that terminate at the low angle thrust fault, the Qomolangma Detachment. This detachment separates it from the underlying Yellow Band. The lower five metres of the Qomolangma Formation overlying this detachment are very highly deformed.

The bulk of Mount Everest, between 7,000 and 8,600 m, consists of the North Col Formation, of which the Yellow Band forms its upper part between 8,200 to 8,600 m. The Yellow Band consists of intercalated beds of diopsite-epidote-bearing marble, which weathers a distinctive yellowish brown, and muscovite-biotite phyllite and semischist. Petrographic analysis of marble collected from about 8,300 m found it to consist as much as five percent of the ghosts of recrystallized crinoid ossicles. The upper five metres of the Yellow Band lying adjacent to the Qomolangma Detachment is badly deformed. A 5–40 cm thick fault breccia separates it from the overlying Qomolangma Formation.

The remainder of the North Col Formation, exposed between 7,000 to 8,200 m on Mount Everest, consists of interlayered and deformed schist, phyllite, and minor marble. Between 7,600 and 8,200 m, the North Col Formation consists chiefly of biotite-quartz phyllite and chlorite-biotite phyllite intercalated with minor amounts of biotite-sericite-quartz schist. Between 7,000 and 7,600 m, the lower part of the North Col Formation consists of biotite-quartz schist intercalated with epidote-quartz schist, biotite-calcite-quartz schist, and thin layers of quartzose marble. These metamorphic rocks appear to the result of the metamorphism of deep sea flysch composed of interbedded, mudstone, shale, clayey sandstone, calcareous sandstone, graywacke, and sandy limestone. The base of the North Col Formation is a regional thrust fault called the “Lhotse detachment”.

Below 7,000 m, the Rongbuk Formation underlies the North Col Formation and forms the base of Mount Everest. It consists of sillminite-K-feldspar grade schist and gneiss intruded by numerous sills and dikes of leucogranite ranging in thickness from one cm to 1,500 m.

Ascents

Early Expedition

In 1885, Clinton Thomas Dent, president of the Alpine Club, suggests that climbing Mount Everest is possible in his book Above the Snow Line.

On June 8, 1924, George Mallory and Andrew Irvine, both of the United Kingdom, made an attempt on the summit via the north col/north ridge route from which they never returned. On May 1, 1999, the Mallory and Irvine Research Expedition found Mallory's body in the predicted search area near the old Chinese camp. Controversy has raged in the mountaineering community as to whether or not one or both of them reached the summit 29 years before the confirmed ascent (and of course, safe descent) of Everest by Sir Edmund Hillary and Tenzing Norgay in 1953. The general consensus among climbers has been that they did not.

Mallory had gone on a speaking tour of the United States the year before in 1923; it was then that he exasperatedly gave the famous reply, "Because it is there," to a New York journalist in response to hearing the question, "Why climb Everest?" for seemingly the thousandth time.

In 1933, Lady Houston, a British millionaire ex-showgirl, funded the Houston Everest Flight of 1933, which saw a formation of aircraft led by the Marquess of Clydesdale fly over the summit in an effort to deploy the British Union Flag at the top.

Early expeditions – such as Bruce's in the 1920s and Hugh Ruttledge's two unsuccessful attempts in 1933 and 1936 – tried to make an ascent of the mountain from Tibet, via the north face. Access was closed from the north to western expeditions in 1950, after the Chinese reasserted control over Tibet. However, in 1950, Bill Tilman and a small party which included Charles Houston, Oscar Houston and Betsy Cowles undertook an exploratory expedition to Everest through Nepal along the route which has now become the standard approach to Everest from the south.

First succesful ascent by Tenzing and Hillary

In 1953, a ninth British expedition, led by John Hunt, returned to Nepal. Hunt selected two climbing pairs to attempt to reach the summit. The first pair (Tom Bourdillon and Charles Evans) came within 100 m (300 feet) of the summit on 26 May, but turned back after becoming exhausted. As planned, their work in route finding and breaking trail and their caches of extra oxygen were of great aid to the following pair. Two days later, the expedition made its second and final assault on the summit with its second climbing pair, the New Zealander Edmund Hillary and Sherpa Tenzing Norgay from Nepal. They reached the summit at 11:30 a.m. local time on May 29, 1953 via the South Col Route. At the time, both acknowledged it as a team effort by the whole expedition, but Tenzing revealed a few years later that Hillary had put his foot on the summit first. They paused at the summit to take photographs and buried a few sweets and a small cross in the snow before descending.

News of the expedition's success reached London on the morning of Queen Elizabeth II's coronation. Returning to Kathmandu a few days later, Hunt (a Briton) and Hillary (a subject of Elizabeth, through her role as head of state of New Zealand) discovered that they had been promptly knighted in the Order of the British Empire, a KBE, for the ascent. Tenzing (a subject of the King of Nepal) was granted the George Medal by the UK. Hunt was ultimately made a life peer in Britain, while Hillary became a founding member of the Order of New Zealand.

First ascents without supplemental oxygen

On May 8, 1978, Reinhold Messner (Italy) and Peter Habeler (Austria) made the first ascent without supplemental oxygen, using the southeast ridge route. On August 20, 1980, Messner reached the summit of the mountain solo for the first time, without supplementary oxygen or support, on the more difficult Northwest route via the North Col to the North Face and the Great Couloir. He climbed for three days entirely alone from his base camp at 6,500 metres (21,300 ft). This route has been noted as the 8th climbing route to the summit.

1996 disaster

During the 1996 climbing season, fifteen people died trying to come down from the summit, making it the deadliest single year in Everest history. Eight of them died on May 11 alone. The disaster gained wide publicity and raised questions about the commercialization of Everest.

Journalist Jon Krakauer, on assignment from Outside magazine, was in one of the affected parties, and afterwards published the bestseller Into Thin Air which related his experience. Anatoli Boukreev, a guide who felt impugned by Krakauer's book, co-authored a rebuttal book called The Climb. The dispute sparked a large debate within the climbing community. In May 2004, Kent Moore, a physicist, and John L. Semple, a surgeon, both researchers from the University of Toronto, told New Scientist magazine that an analysis of weather conditions on May 11 suggested that freak weather caused oxygen levels to plunge approximately 14%.

The storm's impact on climbers on the mountain's other side, the North Ridge, where several climbers also died, was detailed in a first hand account by British filmmaker and writer Matt Dickinson in his book The Other Side of Everest.

2003 - 50th Anniversary of First Ascent

2003 marked the 50th anniversary of the first ascent, and a record number of teams, including some very distinguished climbers, climbed or attempted to climb the mountain.

2005 - Helicopter landing

On 14 May 2005, pilot Didier Delsalle of France landed a Eurocopter AS 350 B3 helicopter on the summit of Mount Everest (without any witness) and took off after about four minutes. (His rotors were continually engaged, constituting a "hover landing", and avoiding the risks of relying on the snow to support the aircraft.) He thereby set rotorcraft world records, for highest of both landing (de facto) and take-off (formally).

Delsalle had also performed, two days earlier, a take-off from the South Col; some press reports suggested that the report of the summit landing was a misunderstanding of a South Col one.

2006 - David Sharp controversy

Double-amputee climber Mark Inglis revealed in an interview with the press on May 23, 2006, that his climbing party, and many others, had passed a distressed climber, David Sharp, on May 15, sheltering under a rock overhang 450 metres below the summit, without attempting a rescue. The revelation sparked wide debate on climbing ethics, especially as applied to Everest. The climbers who left him said that the rescue efforts would be useless and only cause more deaths because of how many people it would have taken to pull him off.

Much of this controversy was captured by the Discovery Channel while filming the television program Everest: Beyond the Limit. A crucial decision affecting the fate of Sharp is shown in the program, where an early returning climber (Max Chaya) is descending and radios to his base camp manager (Russell Brice) that he has found a climber in distress. He is unable to identify Sharp, and Sharp had chosen to climb solo without any support, so he did not identify himself to other climbers. The base camp manager assumes that Sharp is part of a group that has abandoned him, and informs his climber that there is no chance of him being able to help Sharp [at 8000+ meters in altitude, barely anyone has the strength to help another man who is only semi conscious, and Max Chaya is only an amateur mountaineer]. As Sharp's condition deteriorates through the day and other descending climbers pass him, his opportunities for rescue diminish: his legs and feet curl from frost-bite, preventing him from walking; the later descending climbers are lower on oxygen and lack the strength to offer aid; time runs out for any Sherpas to return and rescue him. Most importantly, Sharp's decision to forgo all support leaves him with no margin for recovery.

As this debate raged, on May 26, Australian climber Lincoln Hall was found alive, after being declared dead the day before. He was found by a party of four climbers (Dan Mazur, Andrew Brash, Myles Osborne and Jangbu Sherpa) who, giving up their own summit attempt, stayed with Hall and descended with him and a party of 11 Sherpas sent up to carry him down. Hall later fully recovered. Similar actions have been recorded since, including on May 21, 2007, when Canadian climber Meagan McGrath initiated the successful high-altitude rescue of Nepali Usha Bista.

Various records

According to the Nepalese government, the youngest person to climb Mount Everest was a 15-year-old Sherpa girl, and the youngest foreigner was 18-year-old Californian Samantha Larson in 2007.

The fastest ascent over the northeast ridge was accomplished in 2007 by Austrian climber Christian Stangl, who needed 16h 42min for the 10km distance from Camp III to the summit, just barely beating Italian Hans Kammerlander's record of 17 hours, accomplished in 1996. Both men climbed alone and without supplementary oxygen. The fastest oxygen-supported ascent over the southeast ridge was Nepalese Pemba Dorjie Sherpa's 2004 climb, using 8h 10min for the 17km route. The fastest ascent without supplementary oxygen over the southeast ridge was accomplished by French Marc Batard who needed 22h 30min in 1988.

The oldest climber to successfully reach Mt. Everest's summit was 76-year-old Min Bahadur Sherchan, who did so May 25, 2008

Miss World

The Miss World pageant is an international beauty pageant created in the United Kingdom by Eric Morley in 1951. Currently, Morley's wife, Julia Morley, co-chairs the pageant.

Miss World is oldest surviving major international pageant. The telecast of the final competition is the world's largest live annual beauty pageant television event with global viewers in more than 200 countries.

The winner spends a year travelling to represent the Miss World Organization and its various causes. Traditionally, Miss World lives in London during her reign. The current Miss World is Zhang Zilin of China.

History

Miss World started as the Festival Bikini Contest, in honor of the recently introduced swim wear of the time, but was called "Miss World" by the press. It was originally planned as a one-off event. Upon learning about the upcoming Miss Universe pageant, Morley decided to make the pageant an annual event.

Opposition to the wearing of bikinis led to their replacement with more modest swim wear after the first contest. In 1959, the BBC started broadcasting the competition. The pageant's popularity grew with the advent of television. By the 1990s, the pageant was reaching two billion viewers from almost every country in the world.

In the 1980s, the pageant repositioned itself with the slogan Beauty With a Purpose, with added tests of intelligence and personality. However, the competition has been seen as old-fashioned and rather politically incorrect in its native Britain. Despite the global appeal, the show was not broadcast on any major terrestrial British TV network for several years, until Channel 5 aired it in 1998.

21st century

Eric Morley died as the pageant entered the new century. His wife, Julia, succeeded as chairwoman of the Miss World Organization.

The century saw its first black African winner, Agbani Darego, in 2001. As part of its marketing strategy, Miss World came up with a "You Decide" television special during that edition, featuring the delegates behind the scenes and on the beach, and allowing viewers to either phone in or vote online for their favorites. It also sells its Talent, "Beach Beauty" and Sports events as television specials to broadcasters.

In 2002 the competition was slated for choosing Abuja, the capital city of Nigeria to host its final. This choice was controversial, as a northern Nigerian woman, Amina Lawal, was awaiting death by stoning for adultery under Sharia law there, but Miss World chose to use the publicity surrounding its presence to bring greater global awareness and action to Amina's plight (see Controversies section).

Miss World Organization

The Miss World Organization owns and manages the annual Miss World Finals, a competition that has grown into one of the World’s biggest. Since its launch in 1951, the Miss World Organization has raised more than £250 million for children’s charities. Miss World is franchised in more than 140 countries. Miss World, Limited is a privately held firm, and thus figures for its earnings, expenses and charitable contributions are not publicly available.

Aside from raising millions of pounds for charities around the globe under the banner of its 'Beauty with a Purpose' program, Miss World is also credited with directly influencing a dramatic increase in tourism in Sanya, China, host of the Miss World finals from 2003-05.

The pageant

In the year preceding the global finals, each delegate must win her national title or a specially designated Miss World national preliminary. Miss World's national preliminaries are conducted by their license-holders, who hold the franchise to use the "Miss World" name in their country. The annual final is typically a month long event, with several preliminary galas, dinners, balls and activities, culminating in a globally telecast final show in which the field is narrowed to between 15-20 delegates.

Since 2003 Miss World pageant also features Fast Track events during the preliminary round. The winners of Fast Track events are automatically qualified to enter the final round. Fast Track events which have been used since 2003 are:

Titleholders

Best performances by continental region

Continental Queens of Beauty

Hosts and invited artists

Controversies surrounding the pageant

The Miss World pageant seems to have been the target of many controversies since its inception.

  • In 1970, feminist protesters threw flour bombs during the live event at London's Royal Albert Hall, momentarily scaring the host, Bob Hope.
  • The 1974 winner Helen Morgan resigned four days later after it was discovered she was a single mother.
  • In 1976, several countries went on a boycott, because the pageant included both a Caucasian and African representative for South Africa. In yet another shut-out for the nation for its apartheid policy, South Africa competed for the last time in 1977, before it was welcomed back in 1991 as that policy disintegrated.
  • The 1980 winner Gabriela Brum of Germany resigned one day after winning, initially claiming her boyfriend disapproved. A few days later it emerged that she had been forced to resign after it was discovered that she posed naked for a magazine.
  • In 1996, wide-scale protests took place in Bangalore, India over the hosting of the beauty contest. The swimsuit shootings were moved to Seychelles, and heavy security was placed. Despite the chaos, the pageant's live telecast went on smoothly
  • Just days after her 1998 crowning, Israel's Linor Abargil revealed that she had been raped only two months before the pageant. One of the highlights of her year was seeing her accused rapist convicted.
  • It was in 1998 Miss World Pageant when Miss Ghana unfortunately slipped in the middle of the stage, but was unharmed.

The 2002 Nigeria contest

In the year leading up the finals in Nigeria, several European title holders lobbied their governments and the EU parliament to support Amina's cause. A number of contestants followed the lead of Kathrine Sørland of Norway in boycotting the contest (despite the controversy Sørland would go on to become a semifinalist in both the Miss World and Miss Universe contest), while others such as Costa Rica were instructed by their national governments and parliaments not to attend the contest. Among the other boycotting nations were Denmark, Spain, Switzerland, Panama, Belgium and Kenya. There was further controversy over the possibly suspended participation of France and South Africa, which may or may not have been due to the boycott. For her part, Lawal asked that contestants not suspend their participation in the contest, saying that it was for the good of her country and that they could, as the representative of Sweden had earlier remarked, make a much stronger case for her on the ground in Nigeria.

Despite the increasing international profile the boycott was garnering in the world press, the contest went ahead in Nigeria after being rescheduled to avoid taking place during Ramadan, with many prominent nations sending delegates. Osmel Sousa of Venezuela, one of the world's most influential national directors, famously said "there is no question about it (the participation of Miss Venezuela in the contest). "The trouble did not end there, however. A ThisDay (Lagos, Nigeria) newspaper editorial suggesting that Muhammad, would probably have chosen one of his wives from among the contestants had he been alive to see it, resulted in inter-religious riots that started on November 22 in which over 200 people were killed in the city of Kaduna, along with many houses of worship being burned by religious zealots. Because of these riots, the 2002 pageant was moved to London, following widely circulated reports that the representatives of Canada and Korea had withdrawn from the contest and returned to their respective countries out of safety concerns. A fatwa urging the beheading of the woman who wrote the offending words, Isioma Daniel, was issued in Nigeria, but was declared null and void by the relevant Saudi Arabian authorities. Upon the pageant's return to England, many of the boycotting contestants chose to attend, including Miss Norway, Kathrine Sørland, who was ironically tipped in the last few days as the number one favorite for the crown she had previously boycotted.

The eventual winner of the pageant was Azra Akin of Turkey, the first predominantly Muslim country to hold the title since Egypt in 1954.

phrase

In grammar, a phrase is a group of words that functions as a single unit in the syntax of a sentence.

For example the house at the end of the street (example 1) is a phrase. It acts like a noun. It contains the phrase at the end of the street (example 2), a prepositional phrase which acts like an adjective. Example 2 could be replaced by white, to make the phrase the white house. Examples 1 and 2 contain the phrase the end of the street (example 3) which acts like a noun. It could be replaced by the cross-roads to give the house at the cross-roads.

Most phrases have a or central word which defines the type of phrase. This word is called the head of the phrase. In English the head is often the first word of the phrase. Some phrases, however, can be headless. For example, the rich is a noun phrase composed of a determiner and an adjective, but no noun.

Phrases may be classified by the type of head they take

A phrase is a syntactic structure which has syntactic properties derived from its head.

(from Ancient Greek συν- syn-, “together”, and τάξις táxis, “arrangement”) are the rules of a language that show how the words of that language are to be arranged to make a sentence of that language. The term syntax can also be used to refer to these rules themselves, as in "the syntax of Irish Gaelic". Modern research in syntax attempts to describe languages (Descriptive linguistics) in terms of such rules, and, for many practitioners, to find general rules that apply to all languages. The observations and categorizations of language word order would be an example of that universality. Since the field of syntax attempts to explain grammatical judgments, and not provide them, it is unconcerned with linguistic prescription.

Though all theories of syntax use humans as their object of study, there are some significant differences in outlook. Many linguists (e.g. Noam Chomsky) see syntax as a branch of biology, since they conceive syntax as the study of linguistic knowledge as embodied in the human mind. Others (e.g. Gerald Gazdar) take a more Platonistic view, regarding syntax as the study of an abstract formal system. others also (e.g. Joseph Greenberg) consider grammar as a taxonomical device to reach broad generalizations among languages.

Complexity

A complex phrase consists of several words, whereas a simple phrase consists of only one word. This terminology is especially often used with verb phrases:

  • simple past and present are simple verb, which require just one verb
  • complex verb have one or two aspects added, hence require additional two or three words

"Complex", which is phrase-level, is often confused with "compound", which is word-level. However, there are certain phenomena that formally seem to be phrases but semantically are more like compounds, like "women's magazines", which has the form of a possessive noun phrase, but which refers (just like a compound) to one specific lexeme (i.e. a magazine for women and not some magazine owned by a woman).

Semiotic approaches to the concept of "phrase"

In more semiotic approaches to language, such as the more cognitivist versions of construction grammar, a phrasal structure is not only a certain formal combination of word types whose features are inherited from the head. Here each phrasal structure also expresses some type of conceptual content, be it specific or abstract.

Love That Dare Not Squeak Its Name

Roy and Silo, two chinstrap penguins at the Central Park Zoo in Manhattan, are completely devoted to each other. For nearly six years now, they have been inseparable. They exhibit what in penguin parlance is called "ecstatic behavior": that is, they entwine their necks, they vocalize to each other, they have sex. Silo and Roy are, to anthropomorphize a bit, gay penguins. When offered female companionship, they have adamantly refused it. And the females aren't interested in them, either.

At one time, the two seemed so desperate to incubate an egg together that they put a rock in their nest and sat on it, keeping it warm in the folds of their abdomens, said their chief keeper, Rob Gramzay. Finally, he gave them a fertile egg that needed care to hatch. Things went perfectly. Roy and Silo sat on it for the typical 34 days until a chick, Tango, was born. For the next two and a half months they raised Tango, keeping her warm and feeding her food from their beaks until she could go out into the world on her own. Mr. Gramzay is full of praise for them.

"They did a great job," he said. He was standing inside the glassed-in penguin exhibit, where Roy and Silo had just finished lunch. Penguins usually like a swim after they eat, and Silo was in the water. Roy had finished his dip and was up on the beach.

Roy and Silo are hardly unusual. Milou and Squawk, two young males, are also beginning to exhibit courtship behavior, hanging out with each other, billing and bowing. Before them, the Central Park Zoo had Georgey and Mickey, two female Gentoo penguins who tried to incubate eggs together. And Wendell and Cass, a devoted male African penguin pair, live at the New York Aquarium in Coney Island. Indeed, scientists have found homosexual behavior throughout the animal world.

This growing body of science has been increasingly drawn into charged debates about homosexuality in American society, on subjects from gay marriage to sodomy laws, despite reluctance from experts in the field to extrapolate from animals to humans. Gay groups argue that if homosexual behavior occurs in animals, it is natural, and therefore the rights of homosexuals should be protected. On the other hand, some conservative religious groups have condemned the same practices in the past, calling them "animalistic."

But if homosexuality occurs among animals, does that necessarily mean that it is natural for humans, too? And that raises a familiar question: if homosexuality is not a choice, but a result of natural forces that cannot be controlled, can it be immoral?

The open discussion of homosexual behavior in animals is relatively new. "There has been a certain cultural shyness about admitting it," said Frans de Waal, whose 1997 book, "Bonobo: The Forgotten Ape" (University of California Press), unleashed a torrent of discussion about animal sexuality. Bonobos, apes closely related to humans, are wildly energetic sexually. Studies show that whether observed in the wild or in captivity, nearly all are bisexual, and nearly half their sexual interactions are with the same sex. Female bonobos have been observed to engage in homosexual activity almost hourly.

Before his own book, "American scientists who investigated bonobos never discussed sex at all," said Mr. de Waal, director of the Living Links Center of the Yerkes Primate Center at Emory University in Atlanta. "Or they sometimes would show two females having sex together, and would say, `The females are very affectionate.' "

Then in 1999, Bruce Bagemihl published "Biological Exuberance: Animal Homosexuality and Natural Diversity" (St. Martin's Press), one of the first books of its kind to provide an overview of scholarly studies of same-sex behavior in animals. Mr. Bagemihl said homosexual behavior had been documented in some 450 species. (Homosexuality, he says, refers to any of these behaviors between members of the same sex: long-term bonding, sexual contact, courtship displays or the rearing of young.) Last summer the book was cited by the American Psychiatric Association and other groups in a "friend of the court" brief submitted to the Supreme Court in Lawrence v. Texas, a case challenging a Texas anti-sodomy law. The court struck down the law.

"Sexual Exuberance" was also cited in 2000 by gay rights groups opposed to Ballot Measure 9, a proposed Oregon statute prohibiting teaching about homosexuality or bisexuality in public schools. The measure lost.

In his book Mr. Bagemihl describes homosexual activity in a broad spectrum of animals. He asserts that while same-sex behavior is sometimes found in captivity, it is actually seen more frequently in studies of animals in the wild.

Among birds, for instance, studies show that 10 to 15 percent of female western gulls in some populations in the wild are homosexual. Females perform courtship rituals, like tossing their heads at each other or offering small gifts of food to each other, and they establish nests together. Occasionally they mate with males and produce fertile eggs but then return to their original same-sex partners. Their bonds, too, may persist for years.

Among mammals, male and female bottlenose dolphins frequently engage in homosexual activity, both in captivity and in the wild. Homosexuality is particularly common among young male dolphin calves. One male may protect another that is resting or healing from wounds inflicted by a predator. When one partner dies, the other may search for a new male mate. Researchers have noted that in some cases same-sex behavior is more common for dolphins in captivity.

Male and female rhesus macaques, a type of monkey, also exhibit homosexuality in captivity and in the wild. Males are affectionate to each other, touching, holding and embracing. Females smack their lips at each other and play games like hide-and-seek, peek-a-boo and follow the leader. And both sexes mount members of their own sex.

Paul L. Vasey, a professor of psychology and neuroscience at the University of Lethbridge in Canada, who studies homosexual behavior in Japanese macaques, is editing a new book on homosexual behavior in animals, to be published by Cambridge University Press. This kind of behavior among animals has been observed by scientists as far back as the 1700's, but Mr. Vasey said one reason there had been few books on the topic was that "people don't want to do the research because they don't want to have suspicions raised about their sexuality."

Some scientists say homosexual behavior in animals is not necessarily about sex. Marlene Zuk, a professor of biology at the University of California at Riverside and author of "Sexual Selections: What We Can and Can't Learn About Sex From Animals" (University of California Press, 2002), notes that scientists have speculated that homosexuality may have an evolutionary purpose, ensuring the survival of the species. By not producing their own offspring, homosexuals may help support or nurture their relatives' young. "That is a contribution to the gene pool," she said.

For Janet Mann, a professor of biology and psychology at Georgetown University, who has studied same-sex behavior in dolphin calves, their homosexuality "is about bond formation," she said, "not about being sexual for life."

She said that studies showed that adult male dolphins formed long-term alliances, sometimes in large groups. As adults, they cooperate to entice a single female and keep other males from her. Sometimes they share the female, or they may cooperate to help one male. "Male-male cooperation is extremely important," Ms. Mann said. The homosexual behavior of the young calves "could be practicing" for that later, crucial adult period, she added.

But, scientists say, just because homosexuality is observed in animals doesn't mean that it is only genetically based. "Homosexuality is extraordinarily complex and variable," Mr. Bagemihl said. "We look at animals as pure biology and pure genetics, and they are not." He noted that "the occurrence of same-sex behavior in animals provides support for the nurture side as well." He cited as an example the ruff, a type of Arctic sandpiper. There are four different classes of male ruffs, each differing from the others genetically. The two that differ most from each other are most similar in their homosexual behaviors.

Ms. Zuk said, "You have inclinations that are more or less supported by our genes and in some environmental circumstances get expressed." She used the analogy of right- or left-handedness, thought to be genetically based. "But you can teach naturally left-handed children to use their right hand," she pointed out.

Still, scientists warn about drawing conclusions about humans. "For some people, what animals do is a yardstick of what is and isn't natural," Mr. Vasey said. "They make a leap from saying if it's natural, it's morally and ethically desirable."

But he added: "Infanticide is widespread in the animal kingdom. To jump from that to say it is desirable makes no sense. We shouldn't be using animals to craft moral and social policies for the kinds of human societies we want to live in. Animals don't take care of the elderly. I don't particularly think that should be a platform for closing down nursing homes."

Mr. Bagemihl is also wary of extrapolating. "In Nazi Germany, one very common interpretation of homosexuality was that it was animalistic behavior, subhuman," he said.

What the animal studies do show, Ms. Zuk observed, is that "sexuality is a lot broader term than people want to think."

"You have this idea that the animal kingdom is strict, old-fashioned Roman Catholic," she said, "that they have sex just to procreate."

In bonobos, she noted, "you see expressions of sex outside the period when females are fertile. Suddenly you are beginning to see that sex is not necessarily about reproduction."

"Sexual expression means more than making babies," Ms. Zuk said. "Why are we surprised? People are animals."

Part-time work

Working part time can be a good way of balancing your work and your personal commitments. If you work part-time, you have the right to be treated fairly in comparison to your full-time colleagues.

What is a part-time worker?

A part-time worker is someone who works fewer hours than a full-time worker. There's no specific number of hours that makes someone full or part-time, but a full-time worker will usually work 35 hours or more a week.

Part-time workers and 'less favourable treatment'

According to the Part-time Workers (Prevention of Less Favourable Treatment) Regulations, part-timers must be treated at least as well as equivalent full-time workers, unless the reason why not can be objectively justified. An 'equivalent' full-time worker is one doing a similar job on the same type of contract.

The regulations include temporary staff such as agency and casual workers but part time agency workers can't compare themselves to full time permanent workers. The regulations don't stop employers giving better terms to part-timers, perhaps to encourage a more balanced workforce, but the employer will need to be sure that doing this is not against other discrimination laws.

Examples of how the regulations work

The regulations often mean that benefits must be 'pro-rata'. This means that they should be in proportion to your hours, so for example if a full-time worker gets a £1000 bonus, a part-time worker working half the number of hours should get £500.

Below are some examples of issues affected by the regulations. Remember that your employer can treat part timers less favourably (that is, they can break the rules set out below) If this is 'objectively justified' - what 'objectively justified' means is explained later.

Rates of pay

Part-time workers must get at least the same hourly pay rate as a full-timer doing a similar job.

If you're a part-timer, your employer can set the same hours threshold for enhanced overtime pay as for full timers, so you might not get overtime pay until you've worked more than the normal hours of a full-time worker.

Pension opportunities and benefits

Employers should not discriminate between full-time and part-time workers over access to pension schemes. Other company benefits (such as company cars, employee discounts, and health insurance) should be given pro rata if possible. If this is not possible then your employer will have to decide whether or not to offer the benefit to everybody.

Training and career development

Part-time workers mustn't be excluded from training and career development opportunities. Wherever possible, training must be organised at times that suit most workers, including part-timers.

Holidays

All workers have the right to a minimum amount of annual holiday. From 1 October 2007 the statutory minimum entitlement is 4.8 weeks holiday a year, based on your normal working week. For example, if you work:

  • 20 hours a week, your statutory holiday entitlement is 4.8 20-hour weeks
  • three days each week, you have the right to 14.4 days' holiday - that's 4.8 weeks of three days each

Many employers give more than the statutory minimum amount of holiday. Under the regulations part-timers should be treated no less favourably; this normally means that a part time worker will get a pro rata proportion of what the full-time workers get.

Your employer can't round down the number of days given, because this would be unfavourable treatment, but fractions of a day might be given as hours.

Your employer can control when you take your holiday so they can make you take bank holidays from this entitlement when they coincide with your working days.

What 'objectively justified' means

The rules set out above can be broken where there is objective justification for doing so. This means that the employer has to show that the reason is necessary, and the right way to meet a genuine aim of the business. Part-time workers can't be treated less favourably just because they are part-time.

It may not be possible to pro-rate some benefits to part-timers (for example, complementary health-club membership). In this situation your employer would have to decide either to give the benefit to both full and part time staff or (if there was objective justification - for example if the costs outweigh the benefit) not to give part time workers the benefit.

windows vista (part 2)

End-user features

The appearance of Windows Explorer has changed since Windows XP.

  • Windows Aero: The new hardware-based graphical user interface is named Windows Aero, which Jim Allchin has said is an acronym for Authentic, Energetic, Reflective, and Open. The new interface is intended to be cleaner and more aesthetically pleasing than those of previous Windows, including new transparencies, live thumbnails, live icons, and animations, thus providing a new level of eye candy. Laptop users report however that battery life is shortened with the feature enabled.
  • Windows Shell: The new Windows shell is significantly different from Windows XP, offering a new range of organization, navigation, and search capabilities. Windows Explorer's task pane has been removed, integrating the relevant task options into the toolbar. A "Favorite links" pane has been added, enabling one-click access to common directories. The address bar has been replaced with a breadcrumb navigation system. The preview pane allows users to see thumbnails of various files and view the contents of documents. The details pane shows information such as file size and type, and allows viewing and editing of embedded tags in supported file formats. The Start menu has changed as well; it no longer uses ever-expanding boxes when navigating through Programs. The word "Start" itself has been removed in favor of a blue Windows Orb (also called "Pearl").
  • Instant Search (also known as search as you type) : Windows Vista features a new way of searching called Instant Search, which is significantly faster and more in-depth (content-based) than the search features found in any of the previous versions of Windows.
  • Windows Sidebar: A transparent panel anchored to the side of the screen where a user can place Desktop Gadgets, which are small applets designed for a specialized purpose (such as displaying the weather or sports scores). Gadgets can also be placed on other parts of the desktop.
  • Windows Internet Explorer 7: New user interface, tabbed browsing, RSS, a search box, improved printing, Page Zoom, Quick Tabs (thumbnails of all open tabs), Anti-Phishing filter, a number of new security protection features, Internationalized Domain Name support (IDN), and improved web standards support. IE7 in Windows Vista runs in isolation from other applications in the operating system (protected mode); exploits and malicious software are restricted from writing to any location beyond Temporary Internet Files without explicit user consent.
  • Windows Media Player 11, a major revamp of Microsoft's program for playing and organizing music and video. New features in this version include word wheeling (or "search as you type"), a new GUI for the media library, photo display and organization, the ability to share music libraries over a network with other Vista machines, Xbox 360 integration, and support for other Media Center Extenders.
  • Backup and Restore Center: Includes a backup and restore application that gives users the ability to schedule periodic backups of files on their computer, as well as recovery from previous backups. Backups are incremental, storing only the changes each time, minimizing disk usage. It also features Complete PC Backup (available only in Ultimate, Business, and Enterprise versions) which backs up an entire computer as an image onto a hard disk or DVD. Complete PC Backup can automatically recreate a machine setup onto new hardware or hard disk in case of any hardware failures. Complete PC Restore can be initiated from within Windows Vista or from the Windows Vista installation CD in the event the PC is so corrupt that it cannot start up normally from the hard disk.
  • Windows Mail: A replacement for Outlook Express that includes a new mail store that improves stability, and features integrated Instant Search. It has the Phishing Filter like IE7 and Junk mail filtering that is enhanced through regular updates via Windows Update.
  • Windows Calendar is a new calendar and task application.
  • Windows Photo Gallery, a photo and movie library management application. It can import from digital cameras, tag and rate individual items, adjust colors and exposure, create and display slideshows (with pan and fade effects) and burn slideshows to DVD.
  • Windows DVD Maker, a companion program to Windows Movie Maker that provides the ability to create video DVDs based on a user's content. Users can design a DVD with title, menu, video, soundtrack, pan and zoom motion effects on pictures or slides.
  • Windows Media Center, which was previously exclusively bundled as a separate version of Windows XP, known as Windows XP Media Center Edition, has been incorporated into the Home Premium and Ultimate editions of Windows Vista.
  • Games and Games Explorer: Games included with Windows have been modified to showcase Vista's graphics capabilities. New games are Chess Titans, Mahjong Titans and Purble Place. A new Games Explorer special folder holds shortcuts and information to all games on the user's computer.
  • Windows Mobility Center is a control panel that centralizes the most relevant information related to mobile computing (brightness, sound, battery level / power scheme selection, wireless network, screen orientation, presentation settings, etc.).
  • Windows Meeting Space replaces NetMeeting. Users can share applications (or their entire desktop) with other users on the local network, or over the Internet using peer-to-peer technology (higher versions than Starter and Home Basic can take advantage of hosting capabilities, Starter and Home Basic editions are limited to "join" mode only)
  • Shadow Copy automatically creates daily backup copies of files and folders. Users can also create "shadow copies" by setting a System Protection Point using the System Protection tab in the System control panel. The user can be presented multiple versions of a file throughout a limited history and be allowed to restore, delete, or copy those versions. This feature is available only in the Business, Enterprise, and Ultimate editions of Windows Vista and is inherited from Windows Server 2003.
  • Windows Update: Software and security updates have been simplified, now operating solely via a control panel instead of as a web application. Windows Mail's spam filter and Windows Defender's definitions are updated automatically via Windows Update. Users who choose the recommended setting for Automatic Updates will have the latest drivers installed and available when they add a new device.
  • Parental controls: Allows administrators to control which websites, programs and games each standard user can use and install. This feature is not included in the Business or Enterprise editions of Vista.
  • Windows SideShow: Enables the auxiliary displays on newer laptops or on supported Windows Mobile devices. It is meant to be used to display device gadgets while the computer is on or off.
  • Speech recognition is integrated into Vista. It features a redesigned user interface and configurable command-and-control commands. Unlike the Office 2003 version, which works only in Office and WordPad, Speech Recognition in Windows Vista works for any accessible application. In addition, it currently supports several languages: British and American English, Spanish, French, German, Chinese (Traditional and Simplified) and Japanese.
  • New fonts, including several designed for screen reading, and improved Chinese (Yahei, JhengHei), Japanese (Meiryo) and Korean (Malgun) fonts. ClearType has also been enhanced and enabled by default.
  • Problem Reports and Solutions, a control panel which allows users to view previously sent problems and any solutions or additional information that is available.
  • Improved audio controls allow the system-wide volume or volume of individual audio devices and even individual applications to be controlled separately. New audio functionalities such as Room Correction, Bass Management, Speaker Fill and Headphone virtualization have also been incorporated.
  • Windows System Assessment Tool is a tool used to benchmark system performance. Software such as games can retrieve this rating and modify its own behavior at runtime to improve performance. The benchmark tests CPU, RAM, 2-D and 3-D graphics acceleration, Graphics Memory and Hard disk space.
  • Windows Ultimate Extras: The Ultimate edition of Windows Vista provides, via Windows Update, access to some additional features. These are a collection of additional MUI language packs, Texas Hold 'Em (a Poker game), BitLocker and EFS enhancements which allow users to backup their encryption key online in a Digital Locker, and Windows Dreamscene, which enables the use of videos in MPEG and WMV formats as the desktop background. On April 21st 2008, Microsoft launched two more Ultimate Extras; a new Windows sound scheme, and a content pack for Dreamscene.
  • Disk Management: The Logical Disk Manager in Windows Vista supports shrinking and expanding volumes on-the-fly.
  • Reliability and Performance Monitor includes various tools for tuning and monitoring system performance and resources activities of CPU, disks, network, memory and other resources. It shows the operations on files, the opened connections, etc.

Windows Vista (part1)

Windows Vista

Windows Vista (pronounced ) is a line of operating systems developed by Microsoft for use on personal computers, including home and business desktops, laptops, Tablet PCs, and media center. Prior to its announcement on July 22, 2005, Windows Vista was known by its codename "Longhorn". Development was completed on November 8, 2006; over the following three months it was released in stages to computer hardware and software manufacturers, business customers, and retail channels. On January 30, 2007, it was released worldwide to the general public, and was made available for purchase and downloading from Microsoft's web site. The release of Windows Vista comes more than five years after the introduction of its predecessor, Windows XP, the longest time span between successive releases of Microsoft Windows.

Windows Vista contains many changes and new features, including an updated graphical user interface and visual style dubbed Windows Aero, improved searching features, new multimedia creation tools such as Windows DVD Maker, and redesigned networking, audio, print, and display sub-systems. Vista also aims to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and digital media between computers and devices. Windows Vista includes version 3.0 of the .NET Framework, which aims to make it significantly easier for software developers to write applications than with the traditional Windows API.

Microsoft's primary stated objective with Windows Vista, however, has been to improve the state of security in the Windows operating system. One common criticism of Windows XP and its predecessors has been their commonly exploited security vulnerabilities and overall susceptibility to malware, viruses and buffer overflows. In light of this, Microsoft chairman Bill Gates announced in early 2002 a company-wide "Trustworthy Computing initiative" which aims to incorporate security work into every aspect of software development at the company. Microsoft stated that it prioritized improving the security of Windows XP and Windows Server 2003 above finishing Windows Vista, thus delaying its completion.

While these new features and security improvements have garnered positive reviews, Vista has also been the target of much criticism and negative press. Criticism of Windows Vista has targeted high system requirements, its more restrictive licensing terms, the inclusion of a number of new digital rights management technologies aimed at restricting the copying of protected digital media, lack of compatibility with certain pre-Vista hardware and software, and the number of authorization prompts for User Account Control. As a result of these and other issues, Vista has seen adoption and satisfaction rates lower than Windows XP.

Development

Microsoft began work on Windows Vista, known at the time by its codename "Longhorn" in May 2001, five months prior to the release of Windows XP. It was originally expected to ship sometime late in 2003 as a minor step between Windows XP and "Blackcomb", which was planned to be the company's next major operating system release. Gradually, "Longhorn" assimilated many of the important new features and technologies slated for "Blackcomb", resulting in the release date being pushed back several times. Many of Microsoft's developers were also re-tasked with improving the security of Windows XP and Windows Server 2003, both of which had been the target of a number of high-profile security lapses. Faced with ongoing delays and concerns about feature creep, Microsoft announced on August 27, 2004 that it had revised its plans. The original "Longhorn", based on the Windows XP source code, was scrapped, and Longhorn's development started anew, building on the Windows Server 2003 Service Pack 1 codebase, and re-incorporating only the features that would be intended for an actual operating system release. Some previously announced features such as WinFS were dropped or postponed, and a new software development methodology called the "Security Development Lifecycle" was incorporated in an effort to address concerns with the security of the Windows codebase.

After "Longhorn" was named Windows Vista in July 2005, an unprecedented beta-test program was started, involving hundreds of thousands of volunteers and companies. In September of that year, Microsoft started releasing regular Community Technology Previews (CTP) to beta testers. The first of these was distributed at the 2005 Microsoft Professional Developers Conference, and was subsequently released to beta testers and Microsoft Developer Network subscribers. The builds that followed incorporated most of the planned features for the final product, as well as a number of changes to the user interface, based largely on feedback from beta testers. Windows Vista was deemed feature-complete with the release of the "February CTP", released on February 22, 2006, and much of the remainder of work between that build and the final release of the product focused on stability, performance, application and driver compatibility, and documentation. Beta 2, released in late May, was the first build to be made available to the general public through Microsoft's Customer Preview Program. It was downloaded by over five million people. Two release candidates followed in September and October, both of which were made available to a large number of users.

While Microsoft had originally hoped to have the consumer versions of the operating system available worldwide in time for Christmas 2006, it was announced in March 2006 that the release date would be pushed back to January 2007, in order to give the company – and the hardware and software companies which Microsoft depends on for providing device drivers – additional time to prepare. Through much of 2006, analysts and bloggers had speculated that Windows Vista would be delayed further, owing to anti-trust concerns raised by the European Commission and South Korea, and due to a perceived lack of progress with the beta releases. However, with the November 8, 2006 announcement of the completion of Windows Vista, Microsoft's lengthiest operating system development project came to an end.

History of robots

Ancient developments

The idea of artificial people dates at least as far back as the ancient legends of Cadmus, who sowed dragon teeth that turned into soldiers, and the myth of Pygmalion, whose statue of Galatea came to life. In Greek mythology, the deformed god of metalwork (Vulcan or Hephaestus) created mechanical servants, ranging from intelligent, golden handmaidens to more utilitarian three-legged tables that could move about under their own power, and the robot Talos defended Crete. Medieval Persian alchemist Jabir ibn Hayyan included recipes for creating artificial snakes, scorpions, and humans in his coded Book of Stones. Jewish legend tells of the Golem, a clay creature animated by Kabbalistic magic. Similarly, in the Younger Edda, Norse mythology tells of a clay giant, Mökkurkálfi or Mistcalf, constructed to aid the troll Hrungnir in a duel with Thor, the God of Thunder.

In ancient China, a curious account on automata is found in the Lie Zi text, written in the 3rd century BC. Within it there is a description of a much earlier encounter between King Mu of Zhou (1023 BC-957 BC) and a mechanical engineer known as Yan Shi, an 'artificer'. The latter proudly presented the king with a life-size, human-shaped figure of his mechanical handiwork.

The king stared at the figure in astonishment. It walked with rapid strides, moving its head up and down, so that anyone would have taken it for a live human being. The artificer touched its chin, and it began singing, perfectly in tune. He touched its hand, and it began posturing, keeping perfect time...As the performance was drawing to an end, the robot winked its eye and made advances to the ladies in attendance, whereupon the king became incensed and would have had Yen Shih [Yan Shi] executed on the spot had not the latter, in mortal fear, instantly taken the robot to pieces to let him see what it really was. And, indeed, it turned out to be only a construction of leather, wood, glue and lacquer, variously coloured white, black, red and blue. Examining it closely, the king found all the internal organs complete—liver, gall, heart, lungs, spleen, kidneys, stomach and intestines; and over these again, muscles, bones and limbs with their joints, skin, teeth and hair, all of them artificial...The king tried the effect of taking away the heart, and found that the mouth could no longer speak; he took away the liver and the eyes could no longer see; he took away the kidneys and the legs lost their power of locomotion. The king was delighted.

Concepts akin to a robot can be found as long ago as the 4th century BC, when the Greek mathematician Archytas of Tarentum postulated a mechanical bird he called "The Pigeon" which was propelled by steam. Yet another early automaton was the clepsydra, made in 250 BC by Ctesibius of Alexandria, a physicist and inventor from Ptolemaic Egypt. Hero of Alexandria (10-70 AD) made numerous innovations in the field of automata, including one that allegedly could speak.

Medieval developments

Al-Jazari (1136-1206), an Arab Muslim inventor during the Artuqid dynasty, designed and constructed a number of automatic machines, including kitchen appliances, musical automata powered by water, and the first programmable humanoid robot in 1206. Al-Jazari's robot was a boat with four automatic musicians that floated on a lake to entertain guests at royal drinking parties. His mechanism had a programmable drum machine with pegs (cams) that bump into little levers that operate the percussion. The drummer could be made to play different rhythms and different drum patterns by moving the pegs to different locations.

One of the first recorded designs of a humanoid robot was made by Leonardo da Vinci (1452-1519) in around 1495. Da Vinci's notebooks, rediscovered in the 1950s, contain detailed drawings of a mechanical knight able to sit up, wave its arms and move its head and jaw. The design is likely to be based on his anatomical research recorded in the Vitruvian Man. It is not known whether he attempted to build the robot (see: Leonardo's robot).

Early modern developments

An early automaton was created in 1738 by Jacques de Vaucanson, who created a mechanical duck that was able to eat and digest grain, flap its wings, and excrete.

The Japanese craftsman Hisashige Tanaka, known as "Japan's Edison," created an array of extremely complex mechanical toys, some of which were capable of serving tea, firing arrows drawn from a quiver, or even painting a Japanese kanji character. The landmark text Karakuri Zui (Illustrated Machinery) was published in 1796. (T. N. Hornyak, Loving the Machine: The Art and Science of Japanese Robots [New York: Kodansha International, 2006])

In 1898 Nikola Tesla publicly demonstrated a radio-controlled (teleoperated) boat, similar to a modern ROV. Based on his patents U.S. Patent 613,809 , U.S. Patent 723,188 and U.S. Patent 725,605 for "teleautomation", Tesla hoped to develop the wireless torpedo into a weapon system for the US Navy. (Cheney 1989)

Modern Developments

In the 1930s, Westinghouse Electric Corporation made a humanoid robot known as Elektro, exhibited at the 1939 and 1940 World's Fairs.

The first electronic autonomous robots were created by William Grey Walter of the Burden Neurological Institute at Bristol, England in 1948 and 1949. They were named Elmer and Elsie. These robots could sense light and contact with external objects, and use these stimuli to navigate.

It wasn't until the second half of the twentieth century, when integrated circuits were invented, and computers began to double rapidly in power (roughly every two years according to Moore's Law), that it became possible to build robots as we imagine them. Until that time, automatons were the closest things to robots, and while they may have looked humanoid, and their movements were complex, they were not capable of the self-control and decision making that robots are today.

The first truly modern robot, digitally operated, programmable, and teachable, was invented by George Devol in 1954 and was ultimately called the Unimate. It is worth noting that not a single patent was cited against his original robotics patent (U.S. Patent 2,988,237 ). The first Unimate was personally sold by Devol to General Motors in 1960 and installed in 1961 in a plant in Trenton, New Jersey to lift hot pieces of metal from a die casting machine and stack them.

Robot Fatalities

The first human to be killed by a robot was Robert Williams who died at a casting plant in Flat Rock, MI (January 25, 1979).

A better known case is that of 37-year-old Kenji Urada, a Japanese factory worker, in 1981. Urada was performing routine maintenance on the robot, but neglected to shut it down properly, and was accidentally pushed into a grinding machine.

Basic Law

The term basic law is used in some places as an alternative to "constitution". A Basic Law is either a codified constitution, or in countries with uncodified constitutions, a law given to have constitution powers and effect. The name is usually used to imply an interim or transitory nature, or avoid attempting a claim to being "the highest law", often for religious reasons. In West Germany, the term basic law (Grundgesetz) was used, to indicate that the basic law was provisional until the ultimate reunification of Germany, whereupon a new constitution would be adopted. In the event, no constitution was ever adopted, and the basic law was instead extended throughout the entire German territory. Basic law is entrenched in that it overrides ordinary 'statute law' passed by the legislature.

The special administrative regions of the People's Republic of China, namely Hong Kong and Macau, have basic laws as their constitutional documents. The basic laws are the highest authority, respectively, in the regions, while the rights of amendment and interpretation rest with the Standing Committee of the National People's Congress of the People's Republic of China.

Political philosophies

Confucius

The Chinese philosopher Confucius (551-471 BCE) was one of the first thinkers to adopt a distinct approach to political philosophy. His philosophy was "rooted in his belief that a ruler should learn self-discipline, should govern his subjects by his own example, and should treat them with love and concern." His political beliefs were strongly linked to personal ethics and morality, believing that only a morally upright ruler who possessed "de", or virtue, should be able to exercise power, and that the behavior of an individual ought to be consistent with their rank in society. He stated that "Good government consists in the ruler being a ruler, the minister being a minister, the father being a father, and the son being a son."

Plato

The Greek philosopher Plato(428-348 BC), in his book The Republic, argued that all conventional political systems (democracy, monarchy, oligarchy and timarchy) were inherently corrupt, and that the state ought to be governed by an elite class of educated philosopher-rulers, who would be trained from birth and selected on the basis of aptitude: "those who have the greatest skill in watching over the community." This has been characterised as authoritarian and elitist by some later scholars, notably Karl Popper in his book The Open Society and its Enemies, who described Plato's schemes as essentially totalitarian and criticised his apparent advocacy of censorship. The Republic has also been labeled as communist, due to its advocacy of abolishing private property and the family among the ruling classes; however, this view has been discounted by many scholars, as there are implications in the text that this will extend only to the ruling classes, and that ordinary citizens "will have enough private property to make the regulation of wealth and poverty a concern."

Aristotle

In his book Politics, the Greek philosopher Aristotle(384–322BC) asserted that man is, by nature, a political animal. He argued that ethics and politics are closely linked, and that a truly ethical life can only be lived by someone who participates in politics.

Like Plato, Aristotle identified a number of different forms of government, and argued that each "correct" form of government may devolve into a "deviant" form of government, in which its institutions were corrupted. According to Aristotle, kingship, with one ruler, devolves into tyranny; aristocracy, with a small group of rulers, devolves into oligarchy; and polity, with collective ruleby many citizens, devolves into democracy. In this sense, Aristotle does not use the word "democracy" in its modern sense, carrying positive connotations, but in its literal sense of rule by the demos, or common people. A more accurate view of Aristotle denouncing democracy was that it was described as mob rule, or ochlocracy.

Niccolò Machiavelli

In his work The Prince, the Renaissance Italian political theorist Machiavelli put forward a political worldview which described practical methods for an absolute ruler to attain and maintain political power. His work is sometimes viewed as rejecting traditional views of morality for a ruler: "for Machiavelli, there is no moral basis on which to judge the difference between legitimate and illegitimate uses of power." It is from Machiavelli that the term Machiavellian is derived, referring to an amoral person who uses manipulative methods to attain power; his works have been studied and theories practiced by leaders including totalitarians such as Benito Mussolini, and Adolf Hitler, each of whom justified the use of brutality for purposes of state security. However, many scholars have questioned this view of Machiavelli's theory, arguing that "Machiavelli did not invent 'Machiavellianism' and may not even have been a 'Machiavellian' in the sense often ascribed to him." Instead, Machiavelli considered the stability of the state to be the most important goal, and argued that qualities traditionally considered morally desirable, such as generosity, were undesirable in a ruler and would lead to the loss of power.

Thomas Hobbes

In 1651, Thomas Hobbes published his most famous work, Leviathan, in which he proposed a model of early human development to justify the creation of polities, i.e. governed bodies. Hobbes described an ideal state of nature wherein every person had equal right to every resource in nature and was free to use any means to acquire those resources. He claimed that such an arrangement created a “war of all against all” (bellum omnium contra omnes). The book has been interpreted by scholars as posing two "stark alternatives"; total obedience to an absolute ruler, or "a state of nature, which closely resembles civil war...where all have reason to fear a violent death". Hobbes' view can therefore be interpreted as a defense of absolutism, arguing that human beings enter into a social contract for their protection and agree to obey the dictates of the sovereign; in Hobbes' worldview, "the sovereign is nothing more than the personal embodiment of orderly government." Hobbes himself argued "The final cause, end, or design of men (who naturally love liberty, and dominion over others) in the introduction of that restraint upon themselves, in which we see them live in Commonwealths, is the foresight of their own preservation, and of a more contented life thereby."

John Locke

In the First Treatise of Government, Locke refutes the theory of the Divine Right of Kings as put forward by Robert Filmer; he "minutely examines key Biblical passages" and concludes that absolute monarchy is not supported by Christian theology. "Locke singles out Filmer's contention that men are not 'naturally free' as the key issue, for that is the 'ground'...on which Filmer erects his argument for the claim that all 'legitimate' government is 'absolute monarchy'."

In the Second Treatise of Government, Locke examines the concept of the social contract put forward by other theorists such as Thomas Hobbes, but reaches a different conclusion. Although he agreed with Hobbes on the concept of a state of nature before existing forms of government arose, he challenged Hobbes' view that the state of nature was equivalent to a state of war, instead arguing that there were certain natural rights belonging to all human beings, which continued even after a political authority was established. "The state of nature has a law of nature to govern it, which obliges everyone...being all equal and independent, no one ought to harm another in his life, liberty, health or possessions". According to one scholar, the basis of Locke's thought in the Second Treatise is that "contract or consent is the ground of government and fixes its limits...behind [this] doctrine lies the idea of the independence of the individual person." In other words, Locke's view was different from Hobbes' in that he interpreted the idea of the "state of nature" differently, and he argued that people's natural rights were not necessarily eliminated by their consent to be governed by a political authority.

Jean-Jacques Rousseau

The 18th century French philosopher Jean-Jacques Rousseau, in his book The Social Contract, put forward a system of political thought which was closely related to those of Hobbes and Locke, but different in important respects. In the opening sentence of the book, Rousseau argued that "...man was born free, but he is everywhere in chains" He defined political authority and legitimacy as stemming from the "general will", or volonté generale; for Rousseau, "true Sovereignty is directed always at the public good". This concept of the general will implicitly "allows for individual diversity and freedom...[but] also encourages the well-being of the whole, and therefore can conflict with the particular interests of individuals." As such, Rousseau also argues that the people may need a "lawgiver" to draw up a constitution and system of laws, because the general will, "while always morally sound, is sometimes mistaken".

Rousseau's thought has been seen by some scholars as contradictory and inconsistent, and as not addressing the fundamental contradiction between individual freedom and subordination to the needs of society, "the tension that seems to exist between liberalism and communitarianism". As one Catholic scholar argues, "that it [The Social Contract] contains serious contradictions is undeniable...its fundamental principles--the origin of society, absolute freedom and absolute equality of all--are false and unnatural." The Catholic Encyclopedia further argues that Rousseau's concept of the general will would inevitably lead to "the suppression of personality, the reign of force and caprice, the tyranny of the multitude, the despotism of the crowd", i.e. the subordination of the individual to society as a whole.

John Stuart Mill

In the 19th century, John Stuart Mill pioneered the liberal conception of

politics. He saw democracy as the major political development of his era and, in his book On Liberty, advocated stronger protection for individual rights against government and the rule

of the majority. He argued that liberty was the most important right of human beings, and that the only just cause for interfering with the liberty of another person was self-protection. One commentator refers to On Liberty as "the strongest and most eloquent defense of liberalism that we have." Mill also emphasised the importance of freedom of speech, claiming that "we can never be sure that the opinion we are attempting to stifle is a false opinion, and if we were sure, stifling it would be an evil still."

Karl Marx

Karl Marx was among the most influential political philosophers of history. His theories, collectively termed Marxism, were critical of capitalism and argued that in the due course of history, there would be an "inevitable breakdown of capitalism for economic reasons, to be replaced by communism." He defined history in terms of the class struggle between the bourgeoisie, or property-owning classes, and the proletariat, or workers, a struggle intensified by industrialisation: "The development of Modern Industry, therefore, cuts from under its feet the very foundation on which the bourgeoisie produces and appropriates products. What the bourgeoisie therefore produces, above all, are its own grave-diggers. Its fall and the victory of the proletariat are equally inevitable. Utopia for Marx was the classless society in which the state and the church would be very weak or nonexistent. The workers ultimately would own the means of production, state ownership would be a mere transition period, therefore the people would be free. Because the state as Marx knew it would practically disappear over time, there would be no need for borders so individuals would be free to move from nation to nation without prosecution. This latter idea of internationalism is the direct opposition to the Nazi utopia of the Master race and national socialism. Although Marxism is mostly associated with the Soviet Union for obvious reasons, one may also see in the European Union many but not all of Marx's ideas such as universal health care, open border and the free movement of people, and less economic inequality.

Many subsequent political movements have based themselves on Marx's thought, offering widely differing interpretations of communism; these include Marxism-Leninism, Maoism, and libertarian Marxism. Possibly the most influential interpreter of Marxist theory was Lenin, founder of the Soviet Union, who created a revolutionary theory founded on Marxist thinking. However, libertarian Marxist thinkers have challenged Lenin's interpretation of Marx; Cornelius Castoriadis, for instance, described the Soviet Union's system as a form of "bureaucratic capitalism" rather than true communism.

The multiple notions of political power that are put forth range from conventional views that simply revolve around the actions of politicians to those who view political power as an insidious form of institutionalized social control - most notably "anarchists" and "radical capitalists". The main views of political power revolve around normative, post-modern, and pragmatic perspectives.

Normative faces of power debate

The faces of power debate has coalesced into a viable conception of three dimensions of power including decision-making, agenda-setting, and preference-shaping. The decision-making dimension was first put forth by Robert Dahl, who advocated the notion that political power is based in the formal political arena and is measured through voting patterns and the decisions made by politicians. This view has been criticised by many as simplistic, notably by the sociologist G. William Domhoff, who argues that political and economic power is monopolised by the "elite classes".

A second dimension to the notion of political power was added by academics Peter Bachrach and Morton Baratz involving "agenda-setting". Bachrach and Baratz viewed power as involving both the formal political arena and behind the scenes agenda-setting by elite groups who could be either politicians and/or others (such as industrialists, campaign contributors, special interest groups and so on), often with a hidden agenda that most of the public may not be aware of. The third dimension of power was added by British academic Steven Lukes who felt that even with this second dimension, some other traits of political power needed to be addressed through the concept of 'preference-shaping'. Lukes developed the concept of the "Three faces of power" - decision-making power, non-decision-making power, and ideological power.

This third dimension is inspired by many Neo-Gramscian views such as cultural hegemony and deals with how civil society and the general public have their preferences shaped for them by those in power through the use of propaganda or the media. Ultimately, this third dimension holds that the general public may not be aware of what decisions are actually in their interest due to the invisible power of elites who work to distort their perceptions. Critics of this view claim that such notions are themselves elitist, which Lukes then clearly admits as one problem of this view and yet clarifies that as long as those who make claims that preferences are being shaped explain their own interests etc., there is room for more transparency.

Postmodern challenge of normative views of power

Some within the postmodern and post-structuralist field claim that power is something that is not in the hands of the few and is rather dispersed throughout society in various ways. As one academic writes, "...postmodernists have argued that due to a variety of inherent biases in the standards by which ”valid“ knowledge has been evaluated...modernist science has tended to reproduce ideological justifications for the perpetuation of long-standing forms of inequality. Thus, it is the strategy of postmodern science...to identify and, thereby, attack the ”deceiving“ power of universalizing scientific epistemologies."

Sidelights on Relativity

by: Albert Einstein
An expanded form of an Address to the Prussian Academy of Sciences in Berlin on January 27th, 1921

One reason why mathematics enjoys special esteem, above all other sciences, is that its laws are absolutely certain and indisputable, while those of all other sciences are to some extent debatable and in constant danger of being overthrown by newly discovered facts. In spite of this, the investigator in another department of science would not need to envy the mathematician if the laws of mathematics referred to objects of our mere imagination, and not to objects of reality. For it cannot occasion surprise that different persons should arrive at the same logical conclusions when they have already agreed upon the fundamental laws (axioms), as well as the methods by which other laws are to be deduced therefrom. But there is another reason for the high repute of mathematics, in that it is mathematics which affords the exact natural sciences a certain measure of security, to which without mathematics they could not attain.

At this point an enigma presents itself which in all ages has agitated inquiring minds. How can it be that mathematics, being after all a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality? Is human reason, then, without experience, merely by taking thought, able to fathom the properties of real things.

In my opinion the answer to this question is, briefly, this:—As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality. It seems to me that complete clearness as to this state of things first became common property through that new departure in mathematics which is known by the name of mathematical logic or "Axiomatics." The progress achieved by axiomatics consists in its having neatly separated the logical-formal from its objective or intuitive content; according to axiomatics the logical-formal alone forms the subject-matter of mathematics, which is not concerned with the intuitive or other content associated with the logical-formal.

Let us for a moment consider from this point of view any axiom of geometry, for instance, the following:—Through two points in space there always passes one and only one straight line. How is this axiom to be interpreted in the older sense and in the more modern sense?

The older interpretation:—Every one knows what a straight line is, and what a point is. Whether this knowledge springs from an ability of the human mind or from experience, from some collaboration of the two or from some other source, is not for the mathematician to decide. He leaves the question to the philosopher. Being based upon this knowledge, which precedes all mathematics, the axiom stated above is, like all other axioms, self-evident, that is, it is the expression of a part of this apriori knowledge.

The more modern interpretation:—Geometry treats of entities which are denoted by the words straight line, point, etc. These entities do not take for granted any knowledge or intuition whatever, but they presuppose only the validity of the axioms, such as the one stated above, which are to be taken in a purely formal sense, i.e. as void of all content of intuition or experience. These axioms are free creations of the human mind. All other propositions of geometry are logical inferences from the axioms (which are to be taken in the nominalistic sense only). The matter of which geometry treats is first defined by the axioms. Schlick in his book on epistemology has therefore characterised axioms very aptly as "implicit definitions."

This view of axioms, advocated by modern axiomatics, purges mathematics of all extraneous elements, and thus dispels the mystic obscurity which formerly surrounded the principles of mathematics.

But a presentation of its principles thus clarified makes it also evident that mathematics as such cannot predicate anything about perceptual objects or real objects. In axiomatic geometry the words "point", "straight line", etc., stand only for empty conceptual schemata. That which gives them substance is not relevant to mathematics.

Yet on the other hand it is certain that mathematics generally, and particularly geometry, owes its existence to the need which was felt of learning something about the relations of real things to one another. The very word geometry, which, of course, means earth-measuring, proves this. For earth-measuring has to do with the possibilities of the disposition of certain natural objects with respect to one another, namely, with parts of the earth, measuring-lines, measuring-wands, etc. It is clear that the system of concepts of axiomatic geometry alone cannot make any assertions as to the relations of real objects of this kind, which we will call practically-rigid bodies. To be able to make such assertions, geometry must be stripped of its merely logical-formal character by the co-ordination of real objects of experience with the empty conceptual frame-work of axiomatic geometry. To accomplish this, we need only add the proposition:—Solid bodies are related, with respect to their possible dispositions, as are bodies in Euclidean geometry of three dimensions. Then the propositions of Euclid contain affirmations as to the relations of practically-rigid bodies.

Geometry thus completed is evidently a natural science; we may in fact regard it as the most ancient branch of physics. Its affirmations rest essentially on induction from experience, but not on logical inferences only. We will call this completed geometry "practical geometry", and shall distinguish it in what follows from "purely axiomatic geometry". The question whether the practical geometry of the universe is Euclidean or not has a clear meaning, and its answer can only be furnished by experience. All linear measurement in physics is practical geometry in this sense, so too is geodetic and astronomical linear measurement, if we call to our help the law of experience that light is propagated in a straight line, and indeed in a straight line in the sense of practical geometry.

I attach special importance to the view of geometry which I have just set forth, because without it I should have been unable to formulate the theory of relativity. Without it the following reflection would have been impossible:—In a system of reference rotating relatively to an inert system, the laws of disposition of rigid bodies do not correspond to the rules of Euclidean geometry on account of the Lorentz contraction; thus if we admit non-inert systems we must abandon Euclidean geometry. The decisive step in the transition to general co-variant equations would certainly not have been taken if the above interpretation had not served as a stepping-stone. If we deny the relation between the body of axiomatic Euclidean geometry and the practically-rigid body of reality, we readily arrive at the following view, which was entertained by that acute and profound thinker, H. Poincare:&mdsh;Euclidean geometry is distinguished above all other imaginable axiomatic geometries by its simplicity. Now since axiomatic geometry by itself contains no assertions as to the reality which can be experienced, but can do so only in combination with physical laws, it should be possible and reasonable—whatever may be the nature of reality—to retain Euclidean geometry. For if contradictions between theory and experience manifest themselves, we should rather decide to change physical laws than to change axiomatic Euclidean geometry. If we deny the relation between the practically-rigid body and geometry, we shall indeed not easily free ourselves from the convention that Euclidean geometry is to be retained as the simplest. Why is the equivalence of the practically-rigid body and the body of geometry—which suggests itself so readily—denied by Poincare and other investigators? Simply because under closer inspection the real solid bodies in nature are not rigid, because their geometrical behaviour, that is, their possibilities of relative disposition, depend upon temperature, external forces, etc. Thus the original, immediate relation between geometry and physical reality appears destroyed, and we feel impelled toward the following more general view, which characterizes Poincare's standpoint. Geometry (G) predicates nothing about the relations of real things, but only geometry together with the purport (P) of physical laws can do so. Using symbols, we may say that only the sum of (G) + (P) is subject to the control of experience. Thus (G) may be chosen arbitrarily, and also parts of (P); all these laws are conventions. All that is necessary to avoid contradictions is to choose the remainder of (P) so that (G) and the whole of (P) are together in accord with experience. Envisaged in this way, axiomatic geometry and the part of natural law which has been given a conventional status appear as epistemologically equivalent.

Sub specie aeterni Poincare, in my opinion, is right. The idea of the measuring-rod and the idea of the clock co-ordinated with it in the theory of relativity do not find their exact correspondence in the real world. It is also clear that the solid body and the clock do not in the conceptual edifice of physics play the part of irreducible elements, but that of composite structures, which may not play any independent part in theoretical physics. But it is my conviction that in the present stage of development of theoretical physics these ideas must still be employed as independent ideas; for we are still far from possessing such certain knowledge of theoretical principles as to be able to give exact theoretical constructions of solid bodies and clocks.

Further, as to the objection that there are no really rigid bodies in nature, and that therefore the properties predicated of rigid bodies do not apply to physical reality,—this objection is by no means so radical as might appear from a hasty examination. For it is not a difficult task to determine the physical state of a measuring-rod so accurately that its behaviour relatively to other measuring-bodies shall be sufficiently free from ambiguity to allow it to be substituted for the "rigid" body. It is to measuring-bodies of this kind that statements as to rigid bodies must be referred.

All practical geometry is based upon a principle which is accessible to experience, and which we will now try to realise. We will call that which is enclosed between two boundaries, marked upon a practically-rigid body, a tract. We imagine two practically-rigid bodies, each with a tract marked out on it. These two tracts are said to be "equal to one another" if the boundaries of the one tract can be brought to coincide permanently with the boundaries of the other. We now assume that:

If two tracts are found to be equal once and anywhere, they are equal always and everywhere.

Not only the practical geometry of Euclid, but also its nearest generalisation, the practical geometry of Riemann, and therewith the general theory of relativity, rest upon this assumption. Of the experimental reasons which warrant this assumption I will mention only one. The phenomenon of the propagation of light in empty space assigns a tract, namely, the appropriate path of light, to each interval of local time, and conversely. Thence it follows that the above assumption for tracts must also hold good for intervals of clock-time in the theory of relativity. Consequently it may be formulated as follows:—If two ideal clocks are going at the same rate at any time and at any place (being then in immediate proximity to each other), they will always go at the same rate, no matter where and when they are again compared with each other at one place.—If this law were not valid for real clocks, the proper frequencies for the separate atoms of the same chemical element would not be in such exact agreement as experience demonstrates. The existence of sharp spectral lines is a convincing experimental proof of the above-mentioned principle of practical geometry. This is the ultimate foundation in fact which enables us to speak with meaning of the mensuration, in Riemann's sense of the word, of the four-dimensional continuum of space-time.

The question whether the structure of this continuum is Euclidean, or in accordance with Riemann's general scheme, or otherwise, is, according to the view which is here being advocated, properly speaking a physical question which must be answered by experience, and not a question of a mere convention to be selected on practical grounds. Riemann's geometry will be the right thing if the laws of disposition of practically-rigid bodies are transformable into those of the bodies of Euclid's geometry with an exactitude which increases in proportion as the dimensions of the part of space-time under consideration are diminished.

It is true that this proposed physical interpretation of geometry breaks down when applied immediately to spaces of sub-molecular order of magnitude. But nevertheless, even in questions as to the constitution of elementary particles, it retains part of its importance. For even when it is a question of describing the electrical elementary particles constituting matter, the attempt may still be made to ascribe physical importance to those ideas of fields which have been physically defined for the purpose of describing the geometrical behaviour of bodies which are large as compared with the molecule. Success alone can decide as to the justification of such an attempt, which postulates physical reality for the fundamental principles of Riemann's geometry outside of the domain of their physical definitions. It might possibly turn out that this extrapolation has no better warrant than the extrapolation of the idea of temperature to parts of a body of molecular order of magnitude.

It appears less problematical to extend the ideas of practical geometry to spaces of cosmic order of magnitude. It might, of course, be objected that a construction composed of solid rods departs more and more from ideal rigidity in proportion as its spatial extent becomes greater. But it will hardly be possible, I think, to assign fundamental significance to this objection. Therefore the question whether the universe is spatially finite or not seems to me decidedly a pregnant question in the sense of practical geometry. I do not even consider it impossible that this question will be answered before long by astronomy. Let us call to mind what the general theory of relativity teaches in this respect. It offers two possibilities:—

1. The universe is spatially infinite. This can be so only if the average spatial density of the matter in universal space, concentrated in the stars, vanishes, i.e. if the ratio of the total mass of the stars to the magnitude of the space through which they are scattered approximates indefinitely to the value zero when the spaces taken into consideration are constantly greater and greater.

2. The universe is spatially finite. This must be so, if there is a mean density of the ponderable matter in universal space differing from zero. The smaller that mean density, the greater is the volume of universal space.

I must not fail to mention that a theoretical argument can be adduced in favour of the hypothesis of a finite universe. The general theory of relativity teaches that the inertia of a given body is greater as there are more ponderable masses in proximity to it; thus it seems very natural to reduce the total effect of inertia of a body to action and reaction between it and the other bodies in the universe, as indeed, ever since Newton's time, gravity has been completely reduced to action and reaction between bodies. From the equations of the general theory of relativity it can be deduced that this total reduction of inertia to reciprocal action between masses—as required by E. Mach, for example—is possible only if the universe is spatially finite.

On many physicists and astronomers this argument makes no impression. Experience alone can finally decide which of the two possibilities is realised in nature. How can experience furnish an answer? At first it might seem possible to determine the mean density of matter by observation of that part of the universe which is accessible to our perception. This hope is illusory. The distribution of the visible stars is extremely irregular, so that we on no account may venture to set down the mean density of star-matter in the universe as equal, let us say, to the mean density in the Milky Way. In any case, however great the space examined may be, we could not feel convinced that there were no more stars beyond that space. So it seems impossible to estimate the mean density. But there is another road, which seems to me more practicable, although it also presents great difficulties. For if we inquire into the deviations shown by the consequences of the general theory of relativity which are accessible to experience, when these are compared with the consequences of the Newtonian theory, we first of all find a deviation which shows itself in close proximity to gravitating mass, and has been confirmed in the case of the planet Mercury. But if the universe is spatially finite there is a second deviation from the Newtonian theory, which, in the language of the Newtonian theory, may be expressed thus:—The gravitational field is in its nature such as if it were produced, not only by the ponderable masses, but also by a mass-density of negative sign, distributed uniformly throughout space. Since this factitious mass-density would have to be enormously small, it could make its presence felt only in gravitating systems of very great extent.

Assuming that we know, let us say, the statistical distribution of the stars in the Milky Way, as well as their masses, then by Newton's law we can calculate the gravitational field and the mean velocities which the stars must have, so that the Milky Way should not collapse under the mutual attraction of its stars, but should maintain its actual extent. Now if the actual velocities of the stars, which can, of course, be measured, were smaller than the calculated velocities, we should have a proof that the actual attractions at great distances are smaller than by Newton's law. From such a deviation it could be proved indirectly that the universe is finite. It would even be possible to estimate its spatial magnitude.

Can we picture to ourselves a three-dimensional universe which is finite, yet unbounded?

The usual answer to this question is "No", but that is not the right answer. The purpose of the following remarks is to show that the answer should be "Yes". I want to show that without any extraordinary difficulty we can illustrate the theory of a finite universe by means of a mental image to which, with some practice, we shall soon grow accustomed.

First of all, an observation of epistemological nature. A geometrical-physical theory as such is incapable of being directly pictured, being merely a system of concepts. But these concepts serve the purpose of bringing a multiplicity of real or imaginary sensory experiences into connection in the mind. To "visualise" a theory, or bring it home to one's mind, therefore means to give a representation to that abundance of experiences for which the theory supplies the schematic arrangement. In the present case we have to ask ourselves how we can represent that relation of solid bodies with respect to their reciprocal disposition (contact) which corresponds to the theory of a finite universe. There is really nothing new in what I have to say about this; but innumerable questions addressed to me prove that the requirements of those who thirst for knowledge of these matters have not yet been completely satisfied.

So, will the initiated please pardon me, if part of what I shall bring forward has long been known?

What do we wish to express when we say that our space is infinite? Nothing more than that we might lay any number whatever of bodies of equal sizes side by side without ever filling space. Suppose that we are provided with a great many wooden cubes all of the same size. In accordance with Euclidean geometry we can place them above, beside, and behind one another so as to fill a part of space of any dimensions; but this construction would never be finished; we could go on adding more and more cubes without ever finding that there was no more room. That is what we wish to express when we say that space is infinite. It would be better to say that space is infinite in relation to practically-rigid bodies, assuming that the laws of disposition for these bodies are given by Euclidean geometry.

Another example of an infinite continuum is the plane. On a plane surface we may lay squares of cardboard so that each side of any square has the side of another square adjacent to it. The construction is never finished; we can always go on laying squares—if their laws of disposition correspond to those of plane figures of Euclidean geometry. The plane is therefore infinite in relation to the cardboard squares. Accordingly we say that the plane is an infinite continuum of two dimensions, and space an infinite continuum of three dimensions. What is here meant by the number of dimensions, I think I may assume to be known.

Now we take an example of a two-dimensional continuum which is finite, but unbounded. We imagine the surface of a large globe and a quantity of small paper discs, all of the same size. We place one of the discs anywhere on the surface of the globe. If we move the disc about, anywhere we like, on the surface of the globe, we do not come upon a limit or boundary anywhere on the journey. Therefore we say that the spherical surface of the globe is an unbounded continuum. Moreover, the spherical surface is a finite continuum. For if we stick the paper discs on the globe, so that no disc overlaps another, the surface of the globe will finally become so full that there is no room for another disc. This simply means that the spherical surface of the globe is finite in relation to the paper discs. Further, the spherical surface is a non-Euclidean continuum of two dimensions, that is to say, the laws of disposition for the rigid figures lying in it do not agree with those of the Euclidean plane. This can be shown in the following way. Place a paper disc on the spherical surface, and around it in a circle place six more discs, each of which is to be surrounded in turn by six discs, and so on. If this construction is made on a plane surface, we have an uninterrupted disposition in which there are six discs touching every disc except those which lie on the outside.

[Figure 1: Disks packed onto a plane]

On the spherical surface the construction also seems to promise success at the outset, and the smaller the radius of the disc in proportion to that of the sphere, the more promising it seems. But as the construction progresses it becomes more and more patent that the disposition of the discs in the manner indicated, without interruption, is not possible, as it should be possible by Euclidean geometry of the the plane surface. In this way creatures which cannot leave the spherical surface, and cannot even peep out from the spherical surface into three-dimensional space, might discover, merely by experimenting with discs, that their two-dimensional "space" is not Euclidean, but spherical space.

From the latest results of the theory of relativity it is probable that our three-dimensional space is also approximately spherical, that is, that the laws of disposition of rigid bodies in it are not given by Euclidean geometry, but approximately by spherical geometry, if only we consider parts of space which are sufficiently great. Now this is the place where the reader's imagination boggles. "Nobody can imagine this thing", he cries indignantly. "It can be said, but cannot be thought. I can represent to myself a spherical surface well enough, but nothing analogous to it in three dimensions."

[Figure 2: A circle projected from the sphere unto a plane]

We must try to surmount this barrier in the mind, and the patient reader will see that it is by no means a particularly difficult task. For this purpose we will first give our attention once more to the geometry of two-dimensional spherical surfaces. In the adjoining figure let K be the spherical surface, touched at S by a plane, E, which, for facility of presentation, is shown in the drawing as a bounded surface. Let L be a disc on the spherical surface. Now let us imagine that at the point N of the spherical surface, diametrically opposite to S, there is a luminous point, throwing a shadow L' of the disc L upon the plane E. Every point on the sphere has its shadow on the plane. If the disc on the sphere K is moved, its shadow L' on the plane E also moves. When the disc L is at S, it almost exactly coincides with its shadow. If it moves on the spherical surface away from S upwards, the disc shadow L' on the plane also moves away from S on the plane outwards, growing bigger and bigger. As the disc L approaches the luminous point N, the shadow moves off to infinity, and becomes infinitely great.

Now we put the question, What are the laws of disposition of the disc-shadows L' on the plane E? Evidently they are exactly the same as the laws of disposition of the discs L on the spherical surface. For to each original figure on K there is a corresponding shadow figure on E. If two discs on K are touching, their shadows on E also touch. The shadow-geometry on the plane agrees with the the disc-geometry on the sphere. If we call the disc-shadows rigid figures, then spherical geometry holds good on the plane E with respect to these rigid figures. Moreover, the plane is finite with respect to the disc-shadows, since only a finite number of the shadows can find room on the plane.

At this point somebody will say, "That is nonsense. The disc-shadows are not rigid figures. We have only to move a two-foot rule about on the plane E to convince ourselves that the shadows constantly increase in size as they move away from S on the plane towards infinity." But what if the two-foot rule were to behave on the plane E in the same way as the disc-shadows L'? It would then be impossible to show that the shadows increase in size as they move away from S; such an assertion would then no longer have any meaning whatever. In fact the only objective assertion that can be made about the disc-shadows is just this, that they are related in exactly the same way as are the rigid discs on the spherical surface in the sense of Euclidean geometry.

We must carefully bear in mind that our statement as to the growth of the disc-shadows, as they move away from S towards infinity, has in itself no objective meaning, as long as we are unable to employ Euclidean rigid bodies which can be moved about on the plane E for the purpose of comparing the size of the disc-shadows. In respect of the laws of disposition of the shadows L', the point S has no special privileges on the plane any more than on the spherical surface.

The representation given above of spherical geometry on the plane is important for us, because it readily allows itself to be transferred to the three-dimensional case.

Let us imagine a point S of our space, and a great number of small spheres, L', which can all be brought to coincide with one another. But these spheres are not to be rigid in the sense of Euclidean geometry; their radius is to increase (in the sense of Euclidean geometry) when they are moved away from S towards infinity, and this increase is to take place in exact accordance with the same law as applies to the increase of the radii of the disc-shadows L' on the plane.

After having gained a vivid mental image of the geometrical behaviour of our L' spheres, let us assume that in our space there are no rigid bodies at all in the sense of Euclidean geometry, but only bodies having the behaviour of our L' spheres. Then we shall have a vivid representation of three-dimensional spherical space, or, rather of three-dimensional spherical geometry. Here our spheres must be called "rigid" spheres. Their increase in size as they depart from S is not to be detected by measuring with measuring-rods, any more than in the case of the disc-shadows on E, because the standards of measurement behave in the same way as the spheres. Space is homogeneous, that is to say, the same spherical configurations are possible in the environment of all points. 1 Our space is finite, because, in consequence of the "growth" of the spheres, only a finite number of them can find room in space.

Notes

1) This is intelligible without calculation—but only for the two-dimensional case—if we revert once more to the case of the disc on the surface of the sphere.

In this way, by using as stepping-stones the practice in thinking and visualisation which Euclidean geometry gives us, we have acquired a mental picture of spherical geometry. We may without difficulty impart more depth and vigour to these ideas by carrying out special imaginary constructions. Nor would it be difficult to represent the case of what is called elliptical geometry in an analogous manner. My only aim to-day has been to show that the human faculty of visualisation is by no means bound to capitulate to non-Euclidean geometry.

Technology


Technology is a broad concept that deals with the usage and knowledge of tools and crafts, and how it affects the ability to control and adapt to the environment. In human society, it is a consequence of science and engineering, although several technological advances predate the two concepts. Technology is a term with origins in the Greek "technologia", "τεχνολογία" — "techne", "τέχνη" ("craft") and "logia", "λογία" ("saying").[1] However, a strict definition is elusive; "technology" can refer to material objects of use to humanity, such as machines, hardware or utensils, but can also encompass broader themes, including systems, methods of organization, and techniques. The term can either be applied generally or to specific areas: examples include "construction technology", "medical technology", or "state-of-the-art technology". Other species have also been observed to have created and used technology, including non-human primates, dolphins, and crows.

People's use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.

Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.

Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, claiming that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.





historiography and History of science


History of science and technology

For chronological accounts of the development of science and technology, see history of science and history of technology.

The history of science and technology (HST) is a field of history which examines how humanity's understanding of the natural world (science) and ability to manipulate it (technology) have changed over the millennia. This field of history also studies the cultural, economic, and political impacts of scientific innovation.

Histories of science were originally written by practicing and retired scientists, starting primarily with William Whewell, as a way to communicate the virtues of science to the public. In the early 1930s, after a famous paper given by the Soviet historian Boris Hessen, effort was focused into looking at the ways in which scientific practices were allied with the needs and motivations of their context. After World War II, extensive resources were put into teaching and researching the discipline, with the hopes that it would help the public better understand both science and technology as they came to play an exceedingly prominent role in the world. In the 1960s, especially in the wake of the work done by Thomas Kuhn, the discipline began to serve a very different function, and began to be used as a way to critically examine the scientific enterprise. At the present time it is often closely aligned with the field of Science studies.

Modern mathematical science and physical engineering as it is understood today took form during the scientific revolution, though much of the mathematics and science was built on the work of the Greeks, Egyptians, Mesopotamians, Chinese, Indians and Muslims. See the main articles History of science and History of technology for these respective topics.


Historiography of science

The historiography of science usually refers to the study of History of Science in its disciplinary aspects and practices (methods, theories, schools) and to the study of its own historical development ("history of History of Science", i.e., the history of the academic discipline called History of Science). Alternatively, and confusingly enough, "historiography of science" may be used to refer to the very discipline of History of Science, in such a way as to differentiate the actual history of scientific events (whatever happened in the past, the so-called res gestae) from what we write about them (the historia rerum gestarum). Thus, one may say that "the historiography of science has gone through major changes since the publication of this or that book" (meaning of course that it is not the actual history of science that has changed, but the discipline that concerns itself with studying that history - which, unfortunately, is also called History of Science).

Since the mid-19th century, ideas about the history of science and technology have been tied to important philosophical and practical questions, such as whether scientific conclusions should be regarded as progressing towards truth, and whether freedom is important for scientific research. Put broadly, the field as a whole examines the entire spectrum of human experience relating to science and technology, and how our understanding of that experience has changed over time. Historiography of science is a much more recent discipline than history of science, although they have exerted great mutual influence on each other, through the study of theories, changes in theories, disciplinary and institutional history, the cultural, economic, and political impacts of science and technology, and the impact of society on scientific practice itself.





Science


In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research. This article focuses on the more restricted use of the word. Science as discussed in this article is sometimes termed experimental science to differentiate it from applied science, which is the application of scientific research to specific human needs, though the two are often interconnected.

Etymology

The word science comes through the Old French, and is derived from the Latin word scientia for knowledge, the nominal form of the verb scire, "to know". The Proto-Indo-European (PIE) root that yields scire is *skei-, meaning to "cut, separate, or discern". Other words from the same root include Sanskrit chyati, "he cuts off", Greek schizo, "I split" (hence English schism, schizophrenia), Latin scindo, "I split" (hence English rescind). From the Middle Ages to the Enlightenment, science or scientia meant any systematic recorded knowledge. Science therefore had the same sort of very broad meaning that philosophy had at that time. In other languages, including French, Spanish, Portuguese, and Italian, the word corresponding to science also carries this meaning.

History of science

Well into the eighteenth century, science and natural philosophy were not quite synonymous, but only became so later with the direct use of what would become known formally as the scientific method, which was earlier developed during the Middle Ages and early modern period in Europe and the Middle East (see History of scientific method). Prior to the 18th century, however, the preferred term for the study of nature was natural philosophy, while English speakers most typically referred to the study of the human mind as moral philosophy. By contrast, the word "science" in English was still used in the 17th century to refer to the Aristotelian concept of knowledge which was secure enough to be used as a sure prescription for exactly how to do something. In this differing sense of the two words, the philosopher John Locke in An Essay Concerning Human Understanding wrote that "natural philosophy [the study of nature] is not capable of being made a science".

By the early 1800s, natural philosophy had begun to separate from philosophy, though it often retained a very broad meaning. In many cases, science continued to stand for reliable knowledge about any topic, in the same way it is still used in the broad sense (see the introduction to this article) in modern terms such as library science, political science, and computer science. In the more narrow sense of science, as natural philosophy became linked to an expanding set of well-defined laws (beginning with Galileo's laws, Kepler's laws, and Newton's laws for motion), it became more popular to refer to natural philosophy as natural science. Over the course of the nineteenth century, moreover, there was an increased tendency to associate science with study of the natural world (that is, the non-human world). This move sometimes left the study of human thought and society (what would come to be called social science) in a linguistic limbo by the end of the century and into the next.

Through the 19th century, many English speakers were increasingly differentiating science (meaning a combination of what we now term natural and biological sciences) from all other forms of knowledge in a variety of ways. The now-familiar expression “scientific method,” which refers to the prescriptive part of how to make discoveries in natural philosophy, was almost unused during the early part of the 19th century, but became widespread after the 1870s, though there was rarely totally agreement about just what it entailed. The word "scientist," meant to refer to a systematically-working natural philosopher, (as opposed to an intuitive or empirically-minded one) was coined in 1833 by William Whewell. Discussion of scientists as a special group of people who did science, even if their attributes were up for debate, grew in the last half of the 19th century. Whatever people actually meant by these terms at first, they ultimately depicted science, in the narrow sense of the habitual use of the scientific method and the knowledge derived from it, as something deeply distinguished from all other realms of human endeavor.

By the twentieth century, the modern notion of science as a special brand of information about the world, practiced by a distinct group and pursued through a unique method, was essentially in place. It was used to give legitimacy to a variety of fields through such titles as "scientific" medicine, engineering, advertising, or motherhood. Over the 1900s, links between science and technology also grew increasingly strong. By the end of the century, it is arguable that technology had even begun to eclipse science as a term of public attention and praise. Scholarly studies of science have begun to refer to "technoscience" rather than science of technology separately. Meanwhile, such fields as biotechnology and nanotechnology are capturing the headlines. One author has suggested that, in the coming century, "science" may fall out of use, to be replaced by technoscience or even by some more exotic label such as "techknowledgy."

Philosophy of science

The philosophy of science seeks to understand the nature and justification of scientific knowledge. It has proven difficult to provide a definitive account of the scientific method that can decisively serve to distinguish science from non-science. Thus there are legitimate arguments about exactly where the borders are, leading to the problem of demarcation. There is nonetheless a set of core precepts that have broad consensus among published philosophers of science and within the scientific community at large.

Science is reasoned-based analysis of sensation upon our awareness. As such, the scientific method cannot deduce anything about the realm of reality that is beyond what is observable by existing or theoretical means. When a manifestation of our reality previously considered supernatural is understood in the terms of causes and consequences, it acquires a scientific explanation.

Some of the findings of science can be very counter-intuitive. Atomic theory, for example, implies that a granite boulder which appears a heavy, hard, solid, grey object is actually a combination of subatomic particles with none of these properties, moving very rapidly in space where the mass is concentrated in a very small fraction of the total volume. Many of humanity's preconceived notions about the workings of the universe have been challenged by new scientific discoveries. Quantum mechanics, particularly, examines phenomena that seem to defy our most basic postulates about causality and fundamental understanding of the world around us. Science is the branch of knowledge dealing with people and the understanding we have of our environment and how it works.

There are different schools of thought in the philosophy of scientific method. Methodological naturalism maintains that scientific investigation must adhere to empirical study and independent verification as a process for properly developing and evaluating natural explanations for observable phenomena. Methodological naturalism, therefore, rejects supernatural explanations, arguments from authority and biased observational studies. Critical rationalism instead holds that unbiased observation is not possible and a demarcation between natural and supernatural explanations is arbitrary; it instead proposes falsifiability as the landmark of empirical theories and falsification as the universal empirical method. Critical rationalism argues for the ability of science to increase the scope of testable knowledge, but at the same time against its authority, by emphasizing its inherent fallibility. It proposes that science should be content with the rational elimination of errors in its theories, not in seeking for their verification (such as claiming certain or probable proof or disproof; both the proposal and falsification of a theory are only of methodological, conjectural, and tentative character in critical rationalism). Instrumentalism rejects the concept of truth and emphasizes merely the utility of theories as instruments for explaining and predicting phenomena.

Wall Street set to stumble on AIG loss


NEW YORK - Stock index futures fell on Friday, with financial stocks poised to decline after American International Group (AIG.N: Quote, Profile, Research), the world's largest insurer, reported a larger-than-expected record loss.

Equity markets overseas were pushed lower as the price of oil topped $125 a barrel. Tokyo's main index lost more than 2 percent and Europe's broad benchmark was down by nearly the same amount.

Shares of AIG fell 8.3 percent to $40.50 before the opening bell. The company had to write down assets linked to subprime mortgages and said it would raise $12.5 billion to strengthen its balance sheet.

Another big financial company, Citigroup Inc (C.N: Quote, Profile, Research) said it intends to shed roughly $400 billion of non-core assets in a bid to become more competitive.

AIG "rekindles fears about the credit markets and that we're not through with the write-downs," said Jim Awad, chairman of W.P. Stewart Asset Management in New York. "On top of that, you've got Citi selling assets, which in the long run is a good thing, but it implies several more years of turmoil and restructuring."

S&P 500 futures were down 6.8 points, below fair value, a mathematical formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.

Dow Jones industrial average futures fell 81 points, and Nasdaq 100 futures slipped 8 points.

Transportation and other energy-dependent stocks were likely to sag as U.S. crude for June delivery was up $1.55 to $125.24 a barrel after hitting a record of $125.98. Airlines particularly be under pressure after UBS cut its price target on shares of six major carriers.

Semiconductor shares may lag after graphics chip maker Nvidia Corp (NVDA.O: Quote, Profile, Research) posted quarterly earnings and gross margins that missed estimates. Nvidia shares were down 3 percent at $21.29 before the open.

Stock futures showed a muted reaction to government data showing the U.S. trade deficit narrowed more than expected in March on a record plunge in the value of imports, underscoring the U.S. economic slowdown.

business

In economics, a business (also called firm or enterprise) is a legally recognized organizational entity designed to provide goods and/or services to consumers or corporate entities such as governments, charities or other businesses. Businesses are predominant in capitalist economies, most being privately owned and formed to earn profit to increase the wealth of owners. The owners and operators of a business have as one of their main objectives the receipt or generation of a financial return in exchange for work and acceptance of risk. Notable exceptions include cooperative businesses and state-owned enterprises. Socialistic systems involve either government, public, or worker ownership of most sizable businesses.

The etymology of "business" relates to the state of being busy either as an individual or society as a whole, doing commercially viable and profitable work. The term "business" has at least three usages, depending on the scope — the singular usage (above) to mean a particular company or corporation, the generalized usage to refer to a particular market sector, such as "the music business" and compound forms such as agribusiness, or the broadest meaning to include all activity by the community of suppliers of goods and services. However, the exact definition of business, like much else in the philosophy of business, is a matter of debate.

Business Studies, the study of the management of individuals organizing to maintain collective productivity toward accomplishing particular creative and productive goals (usually to generate profit), is taught as an academic subject in many schools.

Basic forms of ownership

Although forms of business ownership vary by jurisdiction, there are several common forms:

  • Sole proprietorship: A sole proprietorship is a business owned by one person. The owner may operate on his or her own or may employ others. The owner of the business has total and unlimited personal liability of the debts incurred by the business.
  • Cooperative: Often referred to as a "co-op business" or "co-op", a cooperative is a for-profit, limited liability entity that differs from a corporation in that it has members, as opposed to shareholders, who share decision-making authority. Cooperatives are typically classified as either consumer cooperatives or worker cooperatives. Cooperatives are fundamental to the ideology of economic democracy.

Classifications

There are many types of businesses, and, as a result, businesses are classified in many ways. One of the most common focuses on the primary profit-generating activities of a business:

  • Manufacturers produce products, from raw materials or component parts, which they then sell at a profit. Companies that make physical goods, such as cars or pipes, are considered manufacturers.
  • Service businesses offer intangible goods or services and typically generate a profit by charging for labor or other services provided to government, other businesses or consumers. Organizations ranging from house decorators to consulting firms to restaurants and even to entertainers are types of service businesses.
  • Retailers and Distributors act as middle-men in getting goods produced by manufacturers to the intended consumer, generating a profit as a result of providing sales or distribution services. Most consumer-oriented stores and catalogue companies are distributors or retailers. See also: Franchising
  • Agriculture and mining businesses are concerned with the production of raw material, such as plants or minerals.
  • Financial businesses include banks and other companies that generate profit through investment and management of capital.
  • Information businesses generate profits primarily from the resale of intellectual property and include movie studios, publishers and packaged software companies.
  • Utilities produce public services, such as heat, electricity, or sewage treatment, and are usually government chartered.
  • Real estate businesses generate profit from the selling, renting, and development of properties, homes, and buildings.
  • Transportation businesses deliver goods and individuals from location to location, generating a profit on the transportation costs

There are many other divisions and subdivisions of businesses. The authoritative list of business types for North America (although it is widely used around the world[citation needed]) is generally considered to be the North American Industry Classification System, or NAICS. The equivalent European Union list is the NACE.




Business Groups Launch Campaign Against AOL

The online provider's plan to charge fees for bulk e-mail has drawn widespread criticism.

Led by an online rights group, an unlikely coalition of small businesses, medical charities, gun advocates, and others, launched a national campaign yesterday against America Online over plans to charge fees for delivering unsolicited bulk e-mail.

The Electronic Frontier Foundation, a San Francisco-based Internet watchdog, announced the campaign yesterday, calling it a thinly veiled "e-mail tax" on low-end users.

"The Internet is a revolutionary force for free speech, civic organizing, and economic innovation precisely because it is open and accessible to all Internet users equally," organizers said in an open letter signed by the Democratic National Committee, the AFL-CIO, Gun Owners of America, and dozens of other disparate groups.

By mid-afternoon Tuesday, the group had collected more than 500 names in an online petition opposing the fees.

Last October, both AOL and Yahoo announced plans to adopt CertifiedMail, a Silicon Valley-based service that sorts e-mail and collects between a quarter-cent and a cent per message from businesses and other groups, to ensure mass promotional messages get past spam and other inbox filters.

AOL, which is expected to start using the service within the next few months, has said the move is aimed at cutting down on junk e-mail. Yahoo is expected to charge fees only for bulk e-mails dealing with financial transactions.

Notebook


Notebook

A notebook (also notepad, writing pad, drawing pad, legal pad, etc.) is a book, usually of paper, of which various uses can be made, including writing, drawing, and scrapbooking. Notebooks can be distinguished along several dimensions and sub-dimensions:

  • type of surface
  • form factor (size and weight)
  • binding and cover material (including printing and graphics)
  • pre-printed material on writing surfaces (lines, graphics, text)

The specific dimensions determine the most suitable usage for a given type of notebook.

Binding and cover

Principal types of binding are padding, perfect, spiral, comb, sewn, clasp, disc, and pressure, some of which can be combined. Binding methods can affect whether a notebook can lie flat when open and whether the pages are likely to remain attached. The cover material is usually distinct from the writing surface material, more durable, more decorative, and more firmly attached. It also is stiffer than the leaves, even taken together. Cover materials should not contribute to damage or discomfort.

It is frequently cheaper to purchase notebooks that are spiral-bound, meaning that a spiral of wire is looped through large perforations at the top or side of the page. Other bound notebooks are available that use glue to hold the pages together; this process is commonly referred to as "padding". [1] Today it is common for pages in such notebooks to include a thin line of perforations that make it easier to tear out the page. Spiral-bound pages can be torn out but frequently leave thin scraggly strips from the small amount of paper that is within the spiral, as well as an uneven rip along the top of the torn-out page. Moleskine notebooks include a sewn spine that allows it to lie flat.

Variations of notebooks that allow pages to be added, removed, and replaced are bound by either rings, rods, or discs. In each of these systems the pages are modified with perforations that facilitate the specific binding mechanism's ability to secure them. Ring-bound and rod-bound notebooks secure their contents by threading perforated pages around straight or curved prongs. In the open position, the pages can be removed and re-arranged. In the closed position, the pages are kept in order. Disc-bound notebooks remove the open or closed operation by modifying the pages themselves. A page perforated for a disc-bound binding system contains a row of teeth along the side edge of the page that grip onto the outside raised perimeter of individual discs. Pages can be added or removed at any time by peeling the perforations away from each disc.

Preprinting

Notebooks used for drawing and scrapbooking are usually blank. Notebooks for writing usually have some kind of printing on the writing material, if only lines to align writing or facilitate certain kinds of drawing. Inventor's notebooks have page numbers preprinted to support priority claims. Many notebooks have graphic decorations. Personal organizers can have various kinds of preprinted pages.

Uses

Artists often use large notebooks which include wide spaces of blank paper appropriate for drawing. Lawyers are also known for using rather large notebooks known as legal pads that contain lined paper (often yellow in color) and are appropriate for use on tables and desks. These horizontal lines or "rules" are sometimes classified according to their space apart with "wide rule" the farthest, "college rule" closer, "legal rule" slightly closer and "narrow rule" closest, allowing more lines of text per page. When sewn into a pasteboard backing, these may be called composition books, or in smaller signatures may be called "blue books" or exam books and used for essay exams. In contrast, journalists prefer small, hand-held notebooks for portability (often called reporters' notebooks), and sometimes use shorthand when taking notes. Scientists and other researchers use lab notebooks to document their experiments. The pages in lab notebooks are sometimes graph paper to make it easier to plot data. Police officers are required to write notes on what they observed whilst on duty, to do this they use a Police notebook.

Possible electronic successors

Since the late 20th century, many attempts have been made to integrate the simplicity of a notebook with the editing and searching abilities of a computer. Laptop computers began to be called notebooks when they reached a relatively small size in the 1990s, but they did not have any special note-taking ability. Personal digital assistants (PDAs) came next, integrating small liquid crystal displays with a touch-sensitive layer to input graphics and written text. Tablet PCs are considerably larger and provide more writing and navigation space. The fictional PADD of Star Trek is sometimes said to have been the inspiration for PDAs and tablet PCs, but the first PADD was not seen until "Encounter at Farpoint" in 1987, after the first flat calculator-like PDA was made in 1978.

Bill Gates: The skills you need to succeed


Bill Gates: The skills you need to succeed

One of the most important changes of the last 30 years is that digital technology has transformed almost everyone into an information worker.
In almost every job now, people use software and work with information to enable their organisation to operate more effectively. That's true for everyone from the retail store worker who uses a handheld scanner to track inventory to the chief executive who uses business intelligence software to analyse critical market trends.

So if you look at how progress is made and where competitive advantage is created, there's no doubt that the ability to use software tools effectively is critical to succeeding in today's global knowledge economy. A solid working knowledge of productivity software and other IT tools has become a basic foundation for success in virtually any career.

Beyond that, however, I don't think you can overemphasise the importance of having a good background in maths and science. If you look at the most interesting things that have emerged in the last decade - whether it is cool things like portable music devices and video games or more practical things like smart phones and medical technology - they all come from the realm of science and engineering.

The power of software

Today and in the future, many of the jobs with the greatest impact will be related to software, whether it is developing software working for a company like Microsoft or helping other organisations use information technology tools to be successful. Communication skills and the ability to work well with different types of people are very important too.

A lot of people assume that creating software is purely a solitary activity where you sit in an office with the door closed all day and write lots of code.

This isn't true at all.

Software innovation, like almost every other kind of innovation, requires the ability to collaborate and share ideas with other people, and to sit down and talk with customers and get their feedback and understand their needs. I also place a high value on having a passion for ongoing learning. When I was pretty young, I picked up the habit of reading lots of books.

It's great to read widely about a broad range of subjects. Of course today, it's far easier to go online and find information about any topic that interests you. Having that kind of curiosity about the world helps anyone succeed, no matter what kind of work they decide to pursue.

Bill Gates is chairman and one of the founders of Microsoft, the world's largest software company. From July 2008 he will end his day-to-day involvement in the company and focus on the Bill and Melinda Gates Foundation and its global health and education work.

COMMENTS

Without doubt Bill Gates has hit the nail squarely on its head. In 32 years in business I have witnessed the birth of IT and how it has been embraced by business and has changed for ever the way business is being transacted Worldwide.
Kevin Strumpher, Cape Town, South Africa

Yes I agree with Bill's statement. Digital technology has become the irresistible companion in our day to day life. We never stop learning, so life long learning is of paramount importance for a career and life as well. Interpersonal skills and open minded attitude is vital.
Malaka, Colombo

I agree totally with Mr Gates comments. I have always lived with the philosophy of 'the day I stop learning is the day I die' It is something I have tried to instil in my three young children. They like all young children are always asking why questions and rather than give the stock adult answer 'because' we go and look it up on the net or in the library. An enquiring mind is the greatest gift you can give any child.
Paul Marshall, London UK

I have given up my job as an LGV driver to take up a career in IT. I am now a mature student studying a CompTIA A+ course which is IT Technician. This is the best decision of my life - I feel IT is so important in everyday life in this 'progressive' world we live in. IT is about uniting people and sharing skills, and I'm honoured to become a part of it. IT can help with education on all levels and encourage people to learn at their own pace. I really look forward to the future of IT.
Geoffrey Terry, Salisbury, UK

You can't help agreeing with Bill Gates' sentiments on the subject of education. The only thing that disappoints is when he couples culture to success - as perhaps he might, being the figure he is - but personally I question whether to "read widely on a broad range of subjects" should be driven by the wish for success in the minds of our children. Shouldn't it rather just be plain good fun?
Andrew Whitmore, Worcester

I have been privileged to grow up with the internet and have access to all this free knowledge, which undoubtedly translates into almost perfect decisions you make about what paths to take in life. From free video interviews, to blogs, to online bookstores, thank you Bill Gates and everyone who made this happen.
Joaquim Brito, Rio de Janeiro Brazil

I'm glad to see he is saying how important qualifications and getting a good education are - because that is what helps you succeed as much as any mind set. Without the qualifications and experience employers ask for you won't even get a foot in the door to prove you can do the basic things they want you to do.
Mike, London

Digital technology certainly has enhanced my life. Being able to record my own music to what would have been regarded as a highly professional standard twenty years ago, has opened up a whole new vista of creativity, for all ages!
Ken Wright, Bueckeburg, Germany

I am tech savvy. I love to play with technology. I like Bill Gates who is great in the software world. Everybody uses the microsoft software. Digital technology can change. No computer - no life.
Gajendra Kumar, Delhi, India

Absolutely right. When I was young and before affordable PC's I was in a creative, sealed box. The PC has allowed me to create music, design my home and even put together business plans to raise money. None of which I could ever hope to have done without a PC and software.
Percy, Vancouver, Bc

A couple of hundred years ago, the skill set one acquired in one's youth was often valid for one's whole lifetime because the world in which one needed to apply those skills was largely unchanging. Now, in a rapidly changing world, we see more and more roles being fulfilled by automated processes so individuals may need to re-train if their role is consumed by such technology. However, rather than re-train, it is an easier and more natural process to constantly advance oneself and thus surf the wave of advancement rather than be overwhelmed by it and then have to swim hard to get back in front.
John Ellis, Cambridge, UK

Tough Talk

Tough Talk

Women are terrified of conflict, but avoiding a difficult conversation with a colleague because it makes you feel uncomfortable is both unprofessional and unfair. Here's how to prepare for--and lessen the discomfort of--touchy situations.

Margaret considered herself a first class professional in a field where keeping your priorities straight and keeping your cool were both of the essence.

She worked as an emergency medical technician, the only woman in an Oakland, Calif., firehouse, until Jamie, another young nurse, joined the crew. Jamie seemed good-hearted and committed and, as the senior woman on the scene, Margaret willingly took her under her wing. But over time it became clear that Jamie's meek personality was getting in the way. She was afraid to take on many of the responsibilities necessary to be an EMT, like driving the ambulance or staying alone with a critical patient. Margaret knew she should say something but, since the conversation would have been awkward and surely necessitate hurting Jamie's feelings, she kept putting it off.

Then, one rainy night, the crew was called to a multiple car accident, the kind of large-scale emergency that required every member to operate, in EMT parlance, "above their scope of practice." Jamie couldn't do her part and wound up putting the whole team at risk. So, when the exhausted group returned to the firehouse in the early hours of the morning, Margaret finally sat Jamie down for the tough conversation she'd been avoiding all those months.

"I told her that she wasn't EMT material," Margaret recalls. "Her actions had jeopardized all of our lives. I explained that I wouldn't work with her again, and that if she didn't quit herself, I'd see that it happened for her."

Though such life-endangering circumstances might not apply to most workplaces, plenty of otherwise highly competent professional women are familiar with Margaret's impulse to do just about anything to avoid having that difficult conversation with a colleague. In short, we're still terrified of conflict. We want to be nice to and loved by everyone we work with. We don't want to hurt their feelings or rock the boat. In order to keep our spotless reputations, we can twist ourselves into every shape imaginable to avoid discussing a problematic situation, from telling someone they didn't get a promotion to confronting them about not pulling their weight to delivering a pink slip.

But that choice not to address a touchy issue just because it makes us feel uncomfortable is both unprofessional and unfair. Especially as women reach positions of more power and influence, the responsibilities of the job include letting people know when things are going badly as well as when the sailing is smooth. Though such conversations are rarely pleasant, there are a ways to minimize the damage.

In preparing to confront a difficult issue with a colleague, there are three key things to keep in mind:

  • Be gentle
  • Be respectful
  • Practice beforehand

Don't do what Margaret did and wait until the heat of the moment to figure out what to say. Instead, schedule a private meeting with your colleague in a place where there's little chance you'll be interrupted or overheard. The day before, take a few minutes to sit down and plan out what you want say, and how you want to say it. Make notes. If you need spreadsheets or data to back you up, then make sure you have those on hand. If you think it would be helpful, actually do a dry run in front of the mirror or with a friend. The more cool, calm and collected you can be, the smoother things will go for both of you.

Be as specific as you can be about the problem and its possible solutions. General or nebulous criticism doesn't soften the blow. It just makes the situation unnecessarily confusing. Phrase things as kindly as possible, but don't be ambiguous in your convictions. If you tell your assistant that it might be kind of nice if she didn't make quite so many personal calls on office time, she may not understand that you are serious about her paying more focused attention to her work.

Prepare yourself for the kind of response you might get. Depending on the severity of the problem and the temperament of your colleague, you may run into anger, tears, or defensiveness. Do your best not to respond in kind. Understand that your colleague may feel hurt or embarrassed by the issues you've raised. Remind yourself why it's important to have this conversation. The most inconsiderate thing you can do to a coworker is to leave her clueless as to what's really going on.

A marketing executive at a major corporation recently told me about an experience in which she was one of three candidates up for an internal promotion. After an extensive series of interviews and many encouraging e-mail exchanges, she discovered the position had gone to another candidate when it was publicly announced in the company newsletter.

"I found their conduct so unbelievably disrespectful," she told me. "I felt like the least they owed me was a face to face meeting. The message they sent was that once I didn't get that promotion, I no longer mattered to them as a person at all."

She's right. Saving yourself the discomfort of a tough conversation may be the easiest choice, but it's also the most cowardly one. You owe it to your colleagues to be as straightforward and honest with them as you would hope they would be with you. No one loves conflict, but there's one other thing I'm sure most of us can agree upon. If issues hang around unaddressed, they only wind up getting worse.

"If I had it to do over again, I would've spoken to Jamie as soon as I noticed her performance slacking," Margaret told me. "I was so afraid of coming off like the bad guy. But, in certain situations, the bad guy is exactly who you are supposed to be."

Special of language

Mind and language
Innateness and learning


Some of the major issues at the intersection of philosophy of language and philosophy of mind are also dealt with in modern psycholinguistics. Some important questions are: how much of language is innate? Is language acquisition a special faculty in the mind? What's the connection between thought and language?

There are three general perspectives on the issue of language learning. The first is the behaviorist perspective, which dictates that not only is the solid bulk of language learned, but it is learned via conditioning. The second is the hypothesis testing perspective, which understands the child's learning of syntactic rules and meanings to involve the postulation and testing of hypotheses, through the use of the general faculty of intelligence. The final candidate for explanation is the innatist perspective, which states that at least some of the syntactic settings are innate and hardwired, based on certain modules of the mind.

There are varying notions of the structure of the brain when it comes to language, as well. Connectionist models emphasize the idea that a person's lexicon and their thoughts operate in a kind of distributed, associative network. Nativist models assert that there are specialized devices in the brain that are dedicated to language acquisition. Computation models emphasize the notion of a representational language of thought and the logic-like, computational processing that the mind performs over them. Emergentist models focus on the notion that natural faculties are a complex system that emerge out of simpler biological parts. Reductionist models attempt to explain higher level mental processes in terms of the basic low-level neurophysiological activity of the brain.

Language and thought


An important problem which touches both philosophy of language and philosophy of mind is to what extent language influences thought and vice-versa. There have been a number of different perspectives on this issue, each offering a number of insights and suggestions.

Linguists Sapir and Whorf suggested that language limited the extent to which members of a "linguistic community" can think about certain subjects (a hypothesis paralleled in George Orwell's novel "1984"). In other words, language was analytically prior to thought. Philosopher Michael Dummett is also a proponent of the "language-first" viewpoint.

The stark opposite to the Sapir-Whorf position is the notion that thought (or, more broadly, mental content) has priority over language. The "knowledge-first" position can be found, for instance, in the work of Paul Grice. Further, this view is closely associated with Jerry Fodor and his language of thought hypothesis. According to his argument, spoken and written language derive their intentionality and meaning from an internal language encoded in the mind. The main argument in favor of such a view is that the structure of thoughts and the structure of language seem to share a compositional, systematic character. Another argument is that it is difficult to explain how signs and symbols on paper can represent anything meaningful unless some sort of meaning is infused into them by the contents of the mind. One of the main arguments against is that such levels of language can lead to an infinite regress. In any case, many philosophers of mind and language, such as Ruth Millikan, Fred Dretske and Fodor, have recently turned their attention to explaining the meanings of mental contents and states directly.

Another tradition of philosophers has attempted to show that language and thought are coextensive: that there is no way of explaining one without the other. Donald Davidson, in his essay "Thought and Talk", argued that the notion of belief could only arise as a product of public linguistic interaction. Daniel Dennett holds a similar interpretationist view of propositional attitudes. To an extent, the theoretical underpinnings to cognitive semantics (including the notion of semantic framing) suggest the influence of language upon thought. However, the same tradition views meaning and grammar as a function of conceptualization, making it difficult to assess in any straightfoward way.

Some thinkers, like the ancient sophist Gorgias, have questioned whether or not language was capable of capturing thought at all. “...speech can never exactly represent perciptibles, since it is different from them, and perceptibles are apprehended each by the one kind of organ, speech by another. Hence, since the objects of sight cannot be presented to any other organ but sight, and the different sense-organs cannot give their information to one another, similarly speech cannot give any information about perceptibles. Therefore, if anything exists and is comprehended, it is incommunicable.”


Social interaction and language

A common claim is that language is governed by social conventions. Questions inevitably arise on surrounding topics. One question is, "What exactly is a convention, and how do we study it?". And second, "To what extent do conventions even matter in the study of language?". David Lewis proposed a worthy reply to the first question by expounding the view that a convention is a rationally self-perpetuating regularity in behavior. However, this view seems to compete to some extent with the Gricean view of speaker's meaning, requiring either one (or both) to be weakened if both are to be taken as true.

Yet the puzzles do not stop there. Some have questioned whether or not conventions are relevant to the study of meaning at all. Noam Chomsky proposed that the study of language could be done in terms of the I-Language, or internal language of persons. If this is so, then it undermines the pursuit of explanations in terms of conventions, and relegates such explanations to the domain of "meta-semantics". Metasemantics is a term used by philosopher of language Robert Stainton to describe all those fields that attempt to explain how semantic facts arise. One fruitful source of research involves investigation into the social conditions that give rise to, or are associated with, meanings and languages. Etymology (the study of the origins of words) and stylistics (philosophical argumentation over what makes "good grammar", relative to a particular language) are two other examples of fields that are taken to be meta-semantic.

Not surprisingly, many separate (but related) fields have investigated the topic of linguistic convention within their own research paradigms. The presumptions that prop up each theoretical view are of interest to the philosopher of language. For instance, one of the major fields of sociology, symbolic interactionism, is based on the insight that human social organization is based almost entirely on the use of meanings. In consequence, any explanation of a social structure (like an institution) would need to account for the shared meanings which create and sustain the structure.

Rhetoric is the study of the particular words that people use in order to achieve the proper emotional and rational effect in the listener, be it to persuade, provoke, endear, or teach. Some relevant applications of the field include the examination of propaganda and didacticism, the examination of the purposes of swearing and pejoratives (especially how it influences the behavior of others, and defines relationships), or the effects of gendered language. It can also be used to study linguistic transparency (or speaking in an accessible manner), as well as performative utterances and the various tasks that language can perform (called "speech acts"). It also has applications to the study and interpretation of law, and helps give insight to the logical concept of the domain of discourse.

Literary theory is a discipline that overlaps with the philosophy of language. It emphasizes the methods that readers and critics use in understanding a text. This field, being an outgrowth of the study of how to properly interpret messages, is closely tied to the ancient discipline of hermeneutics. The methods taken in the interpretation of texts may extend far beyond literary interpretation, and help in the interpretation of law (for example).
