Nearly one hundred years after its construction, the Royal Tennis Court became symbolic of the brewing French Revolution. On 20 June 1789, the deputies of the Third Estate met there at the time of the Estates General, since the Menus-Plaisirs hotel, their usual meeting place, had been closed by order of the king. On that day, they took an oath not to separate until they had endowed France with a written constitution. This founding scene was immortalised by the painter Jacques-Louis David in a grand fresco, sadly unfinished, called The Tennis Court Oath, which joined the Palace collections in 1921.
We’ve now covered scoring, the first step to learn as a tennis beginner — let’s move on to understanding the court. A tennis court is 78 feet long by 27 feet wide, and divided in half length-wise by the net. At each end of the court, there are white baselines — here, the serves are taken. These are also the out-of-bounds lines — a ball must not bounce beyond them or it’s out and the player who hit the ball loses a point.
The origins of the 15, 30, and 40 scores are believed to be medieval French. The earliest reference is in a ballad by Charles D'Orleans in 1435 which refers to quarante cinque ("forty-five"), which gave rise to modern 40. In 1522 there is a sentence in Latin "we are winning 30, we are winning 45". The first recorded theories about the origin of 15 were published in 1555 and 1579. However, the origins of this convention remain obscure.[3]
Tennis balls were originally made of cloth strips stitched together with thread and stuffed with feathers.[44] Modern tennis balls are made of hollow vulcanized rubber with a felt coating. Traditionally white, the predominant colour was gradually changed to optic yellow in the latter part of the 20th century to allow for improved visibility. Tennis balls must conform to certain criteria for size, weight, deformation, and bounce to be approved for regulation play. The International Tennis Federation (ITF) defines the official diameter as 65.41–68.58 mm (2.575–2.700 in). Balls must weigh between 56.0 and 59.4 g (1.98 and 2.10 oz).[45] Tennis balls were traditionally manufactured in the United States and Europe. Although the process of producing the balls has remained virtually unchanged for the past 100 years, the majority of manufacturing now takes place in the Far East. The relocation is due to cheaper labour costs and materials in the region.[46] Tournaments that are played under the ITF Rules of Tennis must use balls that are approved by the International Tennis Federation (ITF) and be named on the official ITF list of approved tennis balls.[47]

The ITF's Play and Stay campaign promotes playing on smaller courts with slower red, orange and green balls for younger children. This gives children more time and control so they can serve, rally, and score from the first lesson on courts that are sized to fit their bodies. The ITF has mandated that official competition for children under 10 years of age should be played on "Orange" courts 18 m (59 ft) long by 6.4 m (21 ft) wide. Competition for children under 8 years is played on "Red" courts that are 11 m (36 ft) long and 5.5 m (18 ft) wide. The net is always 0.8 m high in the center.[4]
Sportswriter John Wertheim of Sports Illustrated stated in an article in July 2010 that Serena Williams is the greatest female tennis player ever with the argument that "Head-to-head, on a neutral surface (i.e. hard courts), everyone at their best, I can't help feeling that she crushes the other legends.".[120] In a reaction to this article Yahoo sports blog Busted Racket published a list of the top-10 women's tennis players of all time placing Martina Navratilova in first spot.[121] This top-10 list was similar to the one published in June 2008 by the Bleacher Report who also ranked Martina Navratilova as the top female player of all time.[122]

Badminton rackets are light, with top quality rackets weighing between about 70 and 95  grams (with guts ). Modern rackets are composed of carbon fiber composite (graphite reinforced plastic), which may be augmented by a variety of materials. Carbon fiber has an excellent strength to weight ratio, is stiff, and gives excellent kinetic energy transfer. Before the adoption of carbon fiber composite, rackets were made of wood to their excessive weight and cost.
The best marks for this racquet were awarded to the services on which the racquet split the air with power on contact to allow them to reach their targets. However, the EZONE 98 (305 g) will not suit everyone. Some players will enjoy the more damped feel of the DR, while others will prefer the firmer, more powerful response offered by this new version.
Outside Australasia, the single achieved modest commercial success. It peaked at number 78 on the Canadian Hot 100 and remained for five weeks on the chart.[61] The track earned platinum certification from Music Canada, which denotes shipments of 80,000 copies in the country.[62] The single had the similar position on the UK Singles Chart and was certified silver by the British Phonographic Industry for track-equivalent sales of 200,000 units, based on sales and streams.[63][64] It also entered the top 100 of the German Singles Chart, where it reached number 83.[65] Despite not entering the record chart of Norway, the song was certified platinum by IFPI Norway for exceeding sales of 10,000 units in the country.[66] In the US, "Tennis Court" debuted at number 71, which was also its highest placement, on the Billboard Hot 100 chart dated 19 October 2013.[67] The single spent 18 weeks on the chart and had sold 355,000 copies in the US by April 2014.[68][18] It also reached number nine on the Hot Rock Songs, a Billboard auxiliary chart.[69]
You have my dad and brother’s name! Yes, I agree that tennis becomes very technical. I have also struggled with being too technique oriented with my kids. Thanks to Tomaz, I have used feel and imitation a lot more. I think many people in the US are plagued with the notion that faster is better. There is this sense that children should grow up faster and that learning more earlier is better. This turns into the mentality of winning now is better than playing as well as you can later. The two-handed backhand is an example of this. A younger player is much more likely to win with a two-handed backhand at a younger age. The one-hander is very difficult to learn and requires strength and very good footwork. But as I told a local pro I think there is also a downside. By using two forehands it allows people to “cheat” on both sides. My son recently switched to a one-hander just before turning thirteen. It’s hard but he now realizes how important footwork is and his forehand has gotten better because the steps he uses for his backhand have transferred to his forehand. But he is like an alien. He faces almost no other one-handed backhands in competition. So yes, tennis teaching becomes technical because the adult (pros) forget how to think like kids. They also tend to want success fast. Europeans seem to take a longer view. Maybe because their cultures are much older than the American culture.
Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to maneuver the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.
