Pony

A pony is a small horse (Equus ferus caballus). Depending on context, a pony may be a horse that is under an approximate or exact height at the withers, or a small horse with a specific conformation and temperament. There are many different breeds. Compared to other horses, ponies often exhibit thicker manes, tails and overall coat, as well as proportionally shorter legs, wider barrels, heavier bone, thicker necks, and shorter heads with broader foreheads. The word pony derives from the old French poulenet, meaning foal, a young, immature horse, but this is not the modern meaning; unlike a horse foal, a pony remains small when fully grown. However, on occasion, people who are unfamiliar with horses may confuse an adult pony with a foal.

The ancestors of most modern ponies developed small stature because they lived on the margins of livable horse habitat. These smaller animals were domesticated and bred for various purposes all over the Northern Hemisphere. Ponies were historically used for driving and freight transport, as children's mounts, for recreational riding, and later as competitors and performers in their own right. During the Industrial Revolution, particularly in Great Britain, a significant number were used as pit ponies, hauling loads of coal in the mines.

Pony (album)

Pony is the debut and only album by the English psychedelic rock band Spratleys Japs. Released in 1998 on All My Eye And Betty Martin Music, the album was a side-project of Cardiacs frontman Tim Smith and his then partner Joanne Spratley. Although other musicians are credited as playing on the album, it is believed that this was part of an elaborate fictional conceit, and that in fact Smith and Spratley were the only musicians to have been involved with the recording.

Recording

According to the history of the album presented on the All My Eye and Betty Martin website, Pony was conceived as the result of an encounter between Spratley and a displaced American bar band called The Rev-Ups(Heidi Murphy, Mark Donovan and Viv Sherrif), in a dilapidated recording studio in The New Forest. Spratley subsequently introduced Smith to the band, and work began on recording an album in the Autumn of 1998. However, as there is no apparent evidence that the band nor the studio have ever existed, the veracity of this story is in doubt. A further reference was made to the alleged New Forest studio ('Sparrows Wars') on the 2007 album 'Yoni' by Ginger Wildheart which was produced by Tim Smith, where Smith allegedly recorded a church organ for the track 'Smile in Denial'.

Theory

Theory is a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might for example include generalized explanations of how nature works. The word has its roots in ancient Greek, but in modern use it has taken on several different related meanings. A theory is not the same as a hypothesis. A theory provides an explanatory framework for some observation, and from the assumptions of the explanation follows a number of possible hypotheses that can be tested in order to provide support for, or challenge, the theory.

A theory can be normative (or prescriptive), meaning a postulation about what ought to be. It provides "goals, norms, and standards". A theory can be a body of knowledge, which may or may not be associated with particular explanatory models. To theorize is to develop this body of knowledge.

As already in Aristotle's definitions, theory is very often contrasted to "practice" (from Greek praxis, Ï€Ï?ᾶξις) a Greek term for "doing", which is opposed to theory because pure theory involves no doing apart from itself. A classical example of the distinction between "theoretical" and "practical" uses the discipline of medicine: medical theory involves trying to understand the causes and nature of health and sickness, while the practical side of medicine is trying to make people healthy. These two things are related but can be independent, because it is possible to research health and sickness without curing specific patients, and it is possible to cure a patient without knowing how the cure worked.

Chess theory

The game of chess is commonly divided into three phases: the opening, middlegame, and endgame. There is a large body of theory regarding how the game should be played in each of these phases, especially the opening and endgame. Those who write about chess theory, who are often but not necessarily also eminent players, are referred to as "theorists" or "theoreticians".

"Opening theory" commonly refers to consensus, broadly represented by current literature on the openings. "Endgame theory" consists of statements regarding specific positions, or positions of a similar type, though there are few universally applicable principles. "Middlegame theory" often refers to maxims or principles applicable to the middlegame. The modern trend, however, is to assign paramount importance to analysis of the specific position at hand rather than to general principles.

The development of theory in all of these areas has been assisted by the vast literature on the game. In 1913, preeminent chess historian H. J. R. Murray wrote in his 900-page magnum opus A History of Chess that, "The game possesses a literature which in contents probably exceeds that of all other games combined." He estimated that at that time the "total number of books on chess, chess magazines, and newspapers devoting space regularly to the game probably exceeds 5,000". In 1949, B. H. Wood opined that the number had increased to about 20,000.David Hooper and Kenneth Whyld wrote in 1992 that, "Since then there has been a steady increase year by year of the number of new chess publications. No one knows how many have been printed..." The world's largest chess library, the John G. White Collection at the Cleveland Public Library, contains over 32,000 chess books and serials, including over 6,000 bound volumes of chess periodicals. Chess players today also avail themselves of computer-based sources of information.

Theory (mathematical logic)

In mathematical logic, a theory (also called a formal theory) is a set of sentences in a formal language. Usually a deductive system is understood from context. An element of a theory is then called an axiom of the theory, and any sentence that follows from the axioms () is called a theorem of the theory. Every axiom is also a theorem. A first-order theory is a set of first-order sentences.

Theories expressed in formal language generally

When defining theories for foundational purposes, additional care must be taken and normal set-theoretic language may not be appropriate.

The construction of a theory begins by specifying a definite non-empty conceptual class , the elements of which are called statements. These initial statements are often called the primitive elements or elementary statements of the theory, to distinguish them from other statements which may be derived from them.

A theory is a conceptual class consisting of certain of these elementary statements. The elementary statements which belong to are called the elementary theorems of and said to be true. In this way, a theory is a way of designating a subset of which consists entirely of true statements.
