…a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained…
…used in describing what is supposed to happen or be possible, usually with the implication that it does not in fact happen…
…a theory of the structure of atoms stating that electrons revolve in discrete orbits around a positively charged nucleus and that radiation is given off or absorbed only when an electron moves from one orbit to another…
…the branch of mathematics concerned with the analysis of strategies for dealing with competitive situations where the outcome of a participant’s choice of action depends critically on the actions of other participants. Game theory has been applied to contexts in war, business, and biology…
…the branch of mathematics which deals with the formal properties of sets as units (without regard to the nature of their individual constituents) and the expression of other branches of mathematics in terms of sets…
…the theory that light is propagated through the ether by a wave motion imparted to the ether by the molecular vibrations of the radiant body…
…the theory that all matter is made up of tiny indivisible particles (atoms). According to modern interpretations of the theory, the atoms of each element are effectively identical, but differ from those of other elements, and unite to form compounds in fixed proportions…
…the branch of mathematics that deals with complex systems whose behaviour is highly sensitive to slight changes in conditions, so that small alterations can give rise to strikingly great consequences…
…the theory that a political event in one country will cause similar events in neighbouring countries, like a falling domino causing an entire row of upended dominoes to fall…
…a theory that explains physical phenomena in terms of a field and the manner in which it interacts with matter or with other fields…
…a method of applying group theory to the solution of algebraic equations…
…a quantum theory using mathematical functions to describe subatomic interactions in terms of particles that are not directly detectable…
…the mathematical theory of the properties and applications of graphs…
…the branch of mathematics that deals with the properties and relationships of numbers, especially the positive integers…
…a cosmological theory based on the existence of cosmic strings…
…denoting a term, concept, or statement which has meaning only as part of some theory, so that its use implies the acceptance of that theory…
…a philosophical approach to culture, and especially to literature, that considers the social, historical, and ideological forces and structures which produce and constrain it…
…the mathematical study of strategies for optimal decision-making between options involving different risks or expectations of gain or loss depending on the outcome…
…the body of theory which explains the physical properties of matter in terms of the motions of its constituent particles…
…the theory that the solar and stellar systems were developed from a primeval nebula…
…the hypothesis that changes in prices correspond to changes in the monetary supply…
…a theory of matter and energy based on the concept of quanta, especially quantum mechanics…
…a theory which supposes that people attempt to understand the behaviour of others by attributing feelings, beliefs, and intentions to them…
…a branch of mathematics concerned with systems displaying abrupt discontinuous change…
…a belief that some covert but influential organization is responsible for an unexplained event…
…the mathematical study of the coding of information in the form of sequences of symbols, impulses, etc. and of how rapidly such information can be transmitted, for example through computer circuits or telecommunications channels…
…the branch of mathematics that deals with quantities having random distributions…
…the branch of knowledge dealing with the principles and methods by which information is conveyed…
…the theory that states that the definition or criterion of truth is that true propositions correspond to the facts…
…a theory attempting to give a single explanation of the strong, weak, and electromagnetic interactions between subatomic particles…
…a field theory that incorporates quantum mechanics and the principles of the theory of relativity…
…a theory that describes two or more of the four interactions (electromagnetic, gravitational, weak, and strong) previously described by separate theories…
…the Marxist theory that the value of a commodity should be determined by the amount of human labour used in its production…
…the branch of mathematics concerned with the analysis of strategies for dealing with competitive situations where the outcome of a participant’s choice of action depends critically on the actions of other participants. Game theory has been applied to contexts in war, business, and biology…
…the theory that the sun is the centre of the solar system, with the planets (including the earth) orbiting round it…
…the theory that the earth is the stationary centre of the universe, with the planets moving in epicyclic orbits within surrounding concentric spheres…
…the branch of knowledge dealing with the principles and methods by which information is conveyed…
…the dependence of various physical phenomena on relative motion of the observer and the observed objects, especially regarding the nature and behaviour of light, space, time, and gravity…
…the hypothesis that changes in prices correspond to changes in the monetary supply…
…the absence of standards of absolute and universal application…
