Know About The GOLF




Golf is a precision club-and-ball sport, in which competing players (golfers), using many types of clubs, attempt to hit balls into each hole on a golf course while employing the fewest number of strokes. Golf is one of the few ball games that does not require a standardized playing area. Instead, the game is played on golf "courses", each of which features a unique design, although courses typically consist of either nine or 18 holes. Golf is defined, in the rules of golf, as "playing a ball with a club from the teeing ground into the hole by a stroke or successive strokes in accordance with the Rules." Golf competition is generally played for the lowest number of strokes by an individual, known simply as stroke play, or the lowest score on the most individual holes during a complete round by an individual or team, known as match play.
Golf course
A golf course consists of a series of holes, each with a teeing area that is set off by two markers showing the bounds of the legal tee area, fairway, rough and other hazards, and the putting green surrounded by the fringe with the pin (flagstick) and cup. Different levels of grass are varied to increase difficulty, or to allow for putting in the case of the green. While many holes are designed with a direct line-of-sight from the tee-off point to the green, some of the holes may bend, either to the left or to the right. This is called a "dogleg", in reference to a dog's knee. The hole is called a "dogleg left" if the hole angles leftwards and vice versa; sometimes, a hole's direction can bend twice and is called a "double dogleg". A typical golf course consists of 18 holes but nine hole courses are common and can be played twice through for 18 holes.Early Scottish golf courses were primarily laid out on links land, soil covered sand dunes directly inland from beaches.This gave rise to the term golf links, particularly applied to seaside courses and those built on naturally sandy soil inland.

Origin of Golf

The origin of golf is unclear and open to debate. Some historians[who?] trace the sport back to the Roman game of paganica, in which participants used a bent stick to hit a stuffed leather ball. One theory asserts that paganica spread throughout Britain and Europe as the Romans conquered much of the continent, during the first century B.C., and eventually evolved into the modern game.Others cite chuiwan ("chui" means striking and "wan" means small ball) as the progenitor, a Chinese game played between the eighth and 14th centuries.The game is thought to have been introduced into Europe during the Middle Ages. Another early game that resembled modern golf was known as cambuca in England and chambot in France.This game was, in turn, exported to the Low Countries, Germany, and England (where it was called pall-mall, pronounced “pell mell”). Some observers, however, believe that golf descended from the Persian game, chaugán. In addition, kolven (a game involving a ball and curved bats) was played annually in Loenen, Netherlands, beginning in 1297, to commemorate the capture of the assassin of Floris V, a year earlier.
According to the most widely accepted account, however, the modern game originated in Scotland around the 12th century, with shepherds knocking stones into rabbit holes on the current site of the
Royal and Ancient Golf Club of St. Andrews.

Play of the game
Every round of golf is based on playing a number of holes in a given order. A round typically consists of 18 holes that are played in the order determined by the course layout. On a nine-hole course, a standard round consists of two consecutive nine-hole rounds. Playing a hole on a golf course is initiated by putting a ball into play by striking it with a club on the teeing area (also called the "tee box" or simply "the tee.") When this initial stroke (or "shot") is required to be a long one due to the length of the hole, it is usual (but not required) for a golfer to suspend (or "tee") the ball on a tee prior to striking it. A "tee" in this last sense is a small peg which can be used to elevate the ball slightly above the ground up to a few centimeters high. This elevation is at the discretion of the golfer. Tee pegs are commonly made of wood but may be constructed of any material; the ball may even be "tee'd" on a mound of grass or dirt (at one time a small pile of sand placed by the golfer was routinely used and sand was provided at teeing areas for golfers' use).
When the initial shot on a hole is a long-distance shot intended to move the ball a great distance down the fairway, this shot is commonly called a "drive." Shorter holes generally are initiated with "shorter" clubs. Once the ball comes to rest, the golfer strikes it again as many times as necessary using shots that are variously known as a
lay-up, an approach, a "pitch", or a chip, until the ball reaches the green, where he or she then putts the ball into the hole (commonly called "sinking the putt"). The goal of getting the ball into the hole ("holing" the ball) in as few strokes as possible may be impeded by obstacles such as areas of long grass called rough (usually found alongside fairways) which both impedes advancement and makes it harder to advance the golf ball, bunkers ("sand traps"), and water hazards.In most forms of gameplay, each player plays his or her ball until it is holed.
Players can walk or drive in motorized carts over the course. Play can be done either singly or in groups and sometimes accompanied by
caddies, who carry and manage the players' equipment and who are allowed by the rules to give advice on the play of the course.A caddies' advice can only be given to the player or players for whom the caddy is working, and not to competing players.

Basketball Articles


The only essential equipment in a basketball game is the basketball and the court: a flat, rectangular surface with baskets at opposite ends (or in the case of 3-on-3 street basketball, half a court with one basket). Competitive levels require the use of more equipment such as clocks, scoresheets, scoreboard(s), alternating possession arrows, and whistle-operated stop-clock systems.

An outdoor basketball net.
A regulation basketball court in international games is 28 by 15 meters (approx. 92 by 49 ft) and in the NBA is 94 by 50 feet (29 by 15 m). Most courts are made of wood, usually maple.[23] A steel basket with net and backboard hang over each end of the court. At almost all levels of competition, the top of the rim is exactly 10 feet (3.05 m) above the court and 4 feet (1.2 m) inside the baseline. While variation is possible in the dimensions of the court and backboard, it is considered important for the basket to be of the correct height; a rim that is off by but a few inches can have an adverse effect on shooting.
There are also regulations on the size a basketball should be. If women are playing, the official basketball size is 28.5" in circumference (size 6, or a "285 ball") and a weight of 20 oz. For men, the official ball is 29.5" in circumference (size 7, or a "295 ball") and weighs 22 oz.

Basketball


Basketball is a team sport in which two teams of 5 players try to score points against one another by placing a ball through a 10 foot (3.048 m) high hoop (the goal) under organized rules. Basketball is one of the most popular and widely viewed sports in the world.
Points are scored by throwing (shooting) the ball through the basket from above. dunking and slamming the ball into the rim, or any other acrobatic styles to make the ball into the basket from any distance; the team with more points at the end of the game wins, but additional time(overtime) may be issued when the scores of both teams are the same. The ball can be advanced on the court by bouncing it (dribbling) or passing it between teammates. Disruptive physical contact (foul) is penalized and free throws will be issued if the player is fouled while shooting the ball and there are restrictions on how the ball can be handled (violations).
Through time, basketball has developed to involve many common techniques of shooting, passing and dribbling, as well as players' positions, and offensive and defensive structures. Typically, the tallest members of a team will play center or one of two forward positions, while shorter players or those who possess the best ball handling skills and speed, play the guard positions. While competitive basketball is carefully regulated, numerous variations of basketball have developed for casual play. In some countries, basketball is also a popular spectator sport.
While competitive basketball is primarily an indoor sport, played on a basketball court, less regulated variations played in the outdoors have become increasingly popular among both inner city and rural groups.

2010 FIFA World Cup

The 2010 FIFA World Cup will be the 19th FIFA World Cup, the premier international football tournament. It is scheduled to take place between 11 June and 11 July 2010 in South Africa. The 2010 FIFA World Cup will be the culmination of a qualification process that began in August 2007 and involved 204 of the 208 FIFA national teams. As such, it matches the 2008 Summer Olympics as the sports event with the most competing nations.
This will be the first time that the tournament has been hosted by an African nation, after South Africa beat Morocco and Egypt in an all-African bidding process. Italy are the defending champions. The draw for the finals will take place on 4 December 2009 in Cape Town.

Mascot
The official mascot for the 2010 FIFA World Cup is Zakumi, a leopard with green hair. His name comes from "ZA", the international abbreviation for South Africa, and "kumi", a word that means "ten" in various African languages.[4] The mascot's colours reflect those of the host nation's playing strip – yellow and green.

Tom and Jerry



Tom and Jerry is a series of great animated theatrical shorts created by William Hanna and Joseph Barbera for Metro-Goldwyn-Mayer that centered on a never-ending rivalry between a housecat (Tom) and a mouse (Jerry) whose chases and battles often involved comic violence. Hanna and Barbera ultimately wrote and directed one hundred and fourteen Tom and Jerry cartoons at the MGM cartoon studio in Hollywood, California between 1940 and 1957, when the animation unit was closed. The original series is notable for having won the Academy Awards for Best Short Subject (Cartoons) seven times, tying it with Walt Disney's Silly Symphonies as the theatrical animated series with the most Oscars.
Beginning in 1960, in addition to the originals MGM had new shorts produced by Rembrandt Films, led by Gene Deitch in Eastern Europe. Production of Tom and Jerry shorts returned to Hollywood under Chuck Jones's Sib-Tower 12 Productions in 1963; this series lasted until 1967, making it a total of 161 shorts. The cat and mouse stars later resurfaced in television cartoons produced by Hanna-Barbera and Filmation Studios during the 1970s, 1980s, and 1990s, a feature film, Tom and Jerry: The Movie, in 1992 and released domestically in 1993 and in 2000, their first made-for TV short, Tom and Jerry: The Mansion Cat for Cartoon Network. The most recent Tom and Jerry theatrical short, The Karate Guard, was written and co-directed by co-creator Joe Barbera and debuted in Los Angeles cinemas on September 27, 2005.
Today, Time Warner (via its Turner Entertainment division) owns the rights to Tom and Jerry (with Warner Bros. handling distribution). Since the merger, Turner has produced the series, Tom and Jerry Tales for The CW's Saturday morning "The CW4Kids" lineup, as well as the recent Tom and Jerry short, The Karate Guard, in 2005 and a string of Tom and Jerry direct-to-video films - all in collaboration with Warner Bros. Animation.

About robots




A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro-mechanical machine which is guided by computer or electronic programming, and is thus able to do tasks on its own. Another common characteristic is that by its appearance or movements, a robot often conveys a sense that it has intent or agency of its own.
The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as bots.[1] There is no consensus on which machines qualify as robots, but there is general agreement among experts and the public that robots tend to do some or all of the following: move around, operate a mechanical limb, sense and manipulate their environment, and exhibit intelligent behavior, especially behavior which mimics humans or other animals.
There is conflict about whether the term can be applied to remotely operated devices, as the most common usage implies, or solely to devices which are controlled by their software without human intervention. In
South Africa, robot is an informal and commonly used term for a set of traffic lights.
Stories of artificial helpers and companions and attempts to create them have a long history but fully
autonomous machines only appeared in the 20th century. The first digitally operated and programmable robot, the Unimate, was installed in 1961 to lift hot pieces of metal from a die casting machine and stack them. Today, commercial and industrial robots are in widespread use performing jobs more cheaply or with greater accuracy and reliability than humans. They are also employed for jobs which are too dirty, dangerous or dull to be suitable for humans. Robots are widely used in manufacturing, assembly and packing, transport, earth and space exploration, surgery, weaponry, laboratory research, and mass production of consumer and industrial goods.[2]
It is difficult to compare numbers of robots in different countries, since there are different definitions of what a "robot" is. The International Organization for Standardization gives a definition of robot in ISO 8373: "an automatically controlled, reprogrammable, multipurpose, manipulator programmable in three or more axes, which may be either fixed in place or mobile for use in industrial automation applications."[3] This definition is used by the International Federation of Robotics, the European Robotics Research Network (EURON), and many national standards committees.[4]
The Robotics Institute of America (RIA) uses a broader definition: a robot is a "re-programmable multi-functional manipulator designed to move materials, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks".[5] The RIA subdivides robots into four classes: devices that manipulate objects with manual control, automated devices that manipulate objects with predetermined cycles, programmable and servo-controlled robots with continuous point-to-point trajectories, and robots of this last type which also acquire information from the environment and move intelligently in response.
There is no one definition of robot which satisfies everyone, and many people have their own.
[6] For example, Joseph Engelberger, a pioneer in industrial robotics, once remarked: "I can't define a robot, but I know one when I see one."[7] According to Encyclopaedia Britannica, a robot is "any automatically operated machine that replaces human effort, though it may not resemble human beings in appearance or perform functions in a humanlike manner".[8] Merriam-Webster describes a robot as a "machine that looks like a human being and performs various complex acts (as walking or talking) of a human being", or a "device that automatically performs complicated often repetitive tasks", or a "mechanism guided by automatic controls".[9]
Modern robots are usually used in tightly controlled environments such as on assembly lines because they have difficulty responding to unexpected interference. Because of this, most humans rarely encounter robots. However, domestic robots for cleaning and maintenance are increasingly common in and around homes in developed countries, particularly in Japan. Robots can also be found in the military.
