TheoryNoun1. A well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena; "theories can incorporate facts and laws and tested hypotheses"; "true in fact and theory". 2. A tentative theory about the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena; "a scientific hypothesis that survives experimental testing becomes a scientific theory"; "he proposed a fresh theory of alkalis that later was accepted in chemical practices". 3. A belief that can guide behavior; "the architect has a theory that more is less"; "they killed him on the theory that dead men tell no tales".

(From Wikipedia, the free Encyclopedia)
In mathematics, a theory is a set of statements closed under logical implication. In mathematical logic, "theory" is the term for a set of well-formed formulae consisting of certain axioms and all theorems provable from said axioms. Gödel's incompleteness theorem states that no consistent theory, with a finite number of axioms (in a language at least as strong as arithmetic), can include all true statements.
In science, a theory is a model of reality, used for rationalizing, explaining, predicting, and mastering physical phenomena. There is a difference between the technical term and its common usage. A theory has to be something which is in some way testable; for example, one can theorize that an apple will fall when dropped, and then drop an apple, to see what happens. Many scientists, but not all, argue that religious beliefs are not testable, and thus not theories, because they are matters of faith.
According to Stephen Hawking in A Brief History of Time, "a theory is a good theory if it satisfies two requirements: It must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations." He goes on to state..."Any physical theory is always provisional, in the sense that it is only a hypothesis; you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory. On the other hand, you can disprove a theory by finding even a single observation that disagrees with the predictions of the theory."
There are two types of theories; a supposition which is not backed by observation is known as a conjecture, and if backed by observation it is a hypothesis. A theory is different from a theorem. The former is a model of physical events and cannot be proved from basic axioms. The latter is a statement of mathematical fact which logically follows from a set of axioms. A theory is also different from a physical law in that the former is a model of reality whereas the latter is a statement of what has been observed.
The word theoretical is derived from theory, and is used to describe that which has not yet been observed. For example, until recently, black holes were theoretical.
Theories can become accepted if they are able to make correct predictions and avoid incorrect ones. Theories which are simplier, and more mathematically elegant, tend to be accepted over theories which are complex. Theories are more likely to be accepted if they connect a wide range of phenonomena. The process of accepting theories is part of the scientific method.

Lexicography | Devil's Dictionary | TIGHTS, n. An habiliment of the stage designed to reinforce the general acclamation of the press agent with a particular publicity. Public attention was once somewhat diverted from this garment to Miss Lillian Russell's refusal to wear it, and many were the conjectures as to her motive, the guess of Miss Pauline Hall showing a high order of ingenuity and sustained reflection. It was Miss Hall's belief that nature had not endowed Miss Russell with beautiful legs. This theory was impossible of acceptance by the male understanding, but the conception of a faulty female leg was of so prodigious originality as to rank among the most brilliant feats of philosophical speculation! It is strange that in all the controversy regarding Miss Russell's aversion to tights no one seems to have thought to ascribe it to what was known among the ancients as "modesty." The nature of that sentiment is now imperfectly understood, and possibly incapable of exposition with the vocabulary that remains to us. The study of lost arts has, however, been recently revived and some of the arts themselves recovered. This is an epoch of renaissances, and there is ground for hope that the primitive "blush" may be dragged from its hiding-place amongst the tombs of antiquity and hissed on to the stage. |
