Variation (astronomy)
In astronomy, the variation of the Moon is one of the principal perturbation (astronomy), 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 (astronomy), 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, 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 p ...

Variation Of The Field
In heraldry, variations of the field are any of a number of ways that a Field (heraldry), field (or a Charge (heraldry), charge) may be covered with a pattern, rather than a flat Tincture (heraldry), tincture or a simple Divisions of the field, division of the field. Patterning with ordinaries and subordinaries The diminutives of the Ordinary (heraldry), ordinaries are frequently employed to vary the field. Any of these patterns may be Tincture (heraldry)#Counterchanging and countercolouring, counterchanged by the addition of a division line; for example, ''barry argent and azure, counterchanged per fess'' or ''checquy Or (heraldry), Or and gules, counterchanged per chevron''. Barry, paly, bendy, pily, chevronny When the field is patterned with an even number of horizontal (fesswise) stripes, this is described as ''barry'' e.g. of six or eight, usually of a colour and metal specified, e.g. ''barry of six argent and gules'' (this implies that the chiefmost piece is argent). ...

Her achievements included three match races, the Oatlands Stakes, and two editions of the Garden Stakes at Newmarket Racecourse.

Variation (linguistics)
Variation is a characteristic of language: there is more than one way of saying the same thing in a given language. Variation can exist in domains such as pronunciation (e.g., more than one way of pronouncing the same phoneme or the same word), lexicon (e.g., multiple words with the same meaning), grammar (e.g., different syntactic constructions expressing the same grammatical function), and other features. Different communities or individuals speaking the same language may differ from each other in their choices of which of the available linguistic features to use, and how often (inter-speaker variation), and the same speaker may make different choices on different occasions (intra-speaker variation). While diversity of variation exists, there are also some general boundaries on variation. For instance, speakers across distinct dialects of a language tend to preserve the same word order or fit new sounds into the language's established inventory of phonemes (the study of such res ...

Variation (game Tree)
A variation can refer to a specific sequence of successive moves in a turn-based game, often used to specify a hypothetical future state of a game that is being played. Although the term is most commonly used in the context of Chess analysis, it has been applied to other games. It also is a useful term used when describing computer tree-search algorithms (for example minimax) for playing games such as Go{{cite web , url=http://www.andromeda.com/people/ddyer/go/search.html, title=Searches, tree pruning and tree ordering in Go, date=21 December 2007 or Chess. A variation can be any number of steps as long as each step would be legal if it were to be played. It is often as far ahead as a human or computer can calculate; or however long is necessary to reach a particular position of interest. It may also lead to a terminal state in the game, in which case the term "winning variation" or "losing variation" is sometimes used. Principal variation The principal variation refers to the p ...

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 game, board games such as Monopoly (game), ''Monopoly'' and Role-playing game, role-playing games such as ''Dungeons & Dragons''. Board games ''Monopoly (game), Monopoly'' is frequently played with Monopoly_(game)#House_rules, 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.
