During the 19th century the Royal Tennis Court played a variety of different roles. It served as a theatre storeroom, a workshop and storage space, and a studio for the painters Antoine-Jean Gros and then Horace Vernet. It was listed as a national monument in 1848, then became a games room again under the Second Empire. Approaching the centenary of the oath, under the Third Republic, architect Edmond Guillaume was invited to restore it and convert it into a museum of the French Revolution. The architect used original engravings to reconstitute the spirit of the room, which had been modified and had deteriorated over the course of the century. The museum housed the statue of Bailly, busts of the most important signatories of the oath, and a monumental canvas by Luc-Olivier Merson, based on Jacques-Louis David's preparatory drawing. The museum was inaugurated on 20 June 1883 in the presence of Jules Ferry.
I focus on the student ability to improve skills in the court by having constant repetitions of drills. I also make the lesson more attractive for the students by playing with them and make them experience real game practice.  I structure my lessons with short warm up continued by certain amount of drills and finally different games applied to different situations of the game. 
Tennis balls were originally made of cloth strips stitched together with thread and stuffed with feathers.[44] Modern tennis balls are made of hollow vulcanized rubber with a felt coating.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]

Another benefit of post-tensioning is that contractors can build larger slabs using thinner concrete sections, and they don't have to install control joints which can interfere with play. "In order to build a reinforced concrete court that has the same structural capabilities as a post-tensioned court, we would have to install so much steel and concrete that the reinforced court would actually cost more," says Kolkmann. "Also, a reinforced court needs control joints, usually at a spacing of 10 to 15 feet, including in the playing area. Eventually these joints may widen, as well as any cracks that appear."
Tennis is played on a variety of surfaces and each surface has its own characteristics which affect the playing style of the game. There are four main types of courts depending on the materials used for the court surface: clay courts, hard courts, grass courts and carpet courts. The International Tennis Federation (ITF) lists different surfaces and properties and classifies surfaces into one of five pace settings:[5]
Play all your practice games in sets. Tennis is played in sets--you don’t just play one game and then go home! Sets consist of at least six games. The set doesn’t end until one player wins six games and has a margin of two wins over their opponent. For example, if one player has won six games and the other has won five, they’ll have to keep playing until the winner has two more wins than the loser.[6]
Choosing the right tennis racquet is the best way to ensure optimal performance, aside from practice and matches. This is why we at Midwest Sports stocks such a mammoth collection. We want you to find the best racquet for your game. Select among technical options including head size, weight, and balance. Do you prefer comfort, control or power? You can also browse by price and brand.
This really depends on your experience level to be truthful. Many pro players will buy a racket they like and then get it strung with a particular type of string that they like.We don’t really recommend that for the average player. First, do a little string research, then get a racquet that is already strung with a type of string that you think will work well for your playing style. Remember, you can always restring your racquet later if you are not happy with it.

It wasn't until the 16th century that rackets came into use, and the game began to be called "tennis", from the French term tenez, which can be translated as "hold!", "receive!" or "take!", an interjection used as a call from the server to his opponent.[6] It was popular in England and France, although the game was only played indoors where the ball could be hit off the wall. Henry VIII of England was a big fan of this game, which is now known as real tennis.[7] During the 18th and early 19th centuries, as real tennis declined, new racket sports emerged in England.[8]
