Variation (astronomy)
In astronomy, the variation of the Moon is one of the principal perturbations in the motion of the Moon. Discovery The variation was discovered by Tycho Brahe, who noticed that, starting from a lunar eclipse in December 1590, at the times of syzygy (new or full moon), the apparent velocity of motion of the Moon (along its orbit as seen against the background of stars) was faster than expected. On the other hand, at the times of first and last quarter, its velocity was correspondingly slower than expected. (Those expectations were based on the lunar tables widely used up to Tycho's time. They took some account of the two largest irregularities in the Moon's motion, i.e. those now known as the equation of the center and the evection, see also Lunar theory - History.) Variation The main visible effect (in longitude) of the variation of the Moon is that during the course of every month, at the octants of the Moon's phase that follow the syzygies (i.e. halfway between the new o ...

Variation (horse)
Variation (1827–1847) was a British Thoroughbred racehorse and broodmare who won the classic Oaks Stakes at Epsom Downs Racecourse in 1830. The Oaks was Variation's racing debut and she went on to win a total of eight races from fifteen starts. Her other successes included three match races, the Oatlands Stakes, and two editions of the Garden Stakes at Newmarket Racecourse. Her best performance was probably her win in the 1831 Garden Stakes in which she defeated a very strong field over a distance of two miles. She was retired from racing in 1833 and had some success as a broodmare. Background Variation was a bay mare bred in 1827 either by Mr Nowell or by William Scott Stonehewer, Sr. Stonehewer, a "great sporting man" from a "good old Yorkshire family", owned her during her racing career. She was the eighth foal produced by her dam, a daughter of Beningbrough named Johanna Southcote (1811–1834). Variation was the only classic winner sired by Bustard, a horse which ...

Variation (linguistics)
Variation is a characteristic of language: there is more than one way of saying the same thing. Speakers may vary pronunciation ( accent), word choice ( lexicon), or morphology and syntax (sometimes called "grammar"). But while the diversity of variation is great, there seem to be boundaries on variation – speakers do not generally make drastic alterations in sentence word order or use novel sounds that are completely foreign to the language being spoken. Linguistic variation does not equate with language ungrammaticality, but speakers are still (often unconsciously) sensitive to what is and is not possible in their native lect. Variationists study how a language changes by observing it. This is accomplished by looking at authentic data. For example, variation is studied by looking at linguistic and social environments, then the data is analyzed as the change occurs. Variation in research programs must be malleable due to the nature of language itself. This is because language ...

Variation (game)
House rules are unofficial modifications to official game rules adopted by individual groups of players. House rules may include the removal or alteration of existing rules, or the addition of new rules. Such modifications are common in board games such as ''Monopoly'' and role-playing games such as ''Dungeons & Dragons''. Board games ''Monopoly'' is frequently played with slightly different rules to those provided by the manufacturers, to the extent that, according to a reviewer at ''Computer Gaming World,'' "virtually no-one plays the game with the rules as written". Some video game versions of ''Monopoly'' have options where popular house rules can be enabled. In 2014, Hasbro, the publisher of ''Monopoly'', used a Facebook poll to determine the five most popular house rules, then released a "House Rules Edition" of the game incorporating those rules. Role-playing games In role-playing games, the term house rule signifies a deviation of game play from the official rules. ...
