71Scalar field theory — In theoretical physics, scalar field theory can refer to a classical or quantum theory of scalar fields. A field which is invariant under any Lorentz transformation is called a scalar , in contrast to a vector or tensor field. The quanta of the… …
72Bass–Serre theory — is a part of the mathematical subject of group theory that deals with analyzing the algebraic structure of groups acting by automorphisms on simplicial trees. The theory relates group actions on trees with decomposing groups as iterated… …
73Criticism of relativity theory — Criticism of Albert Einstein s theory of relativity was mainly expressed in the early years after its publication on a scientific, pseudoscientific, philosophical, or ideological basis. Reasons for criticism were, for example, alternative… …
74Literary theory — in a strict sense is the systematic study of the nature of literature and of the methods for analyzing literature. [Culler 1997, p.1] However, literary scholarship since the 19th century often includes in addition to, or even instead of literary… …
75Molecular orbital theory — In chemistry, molecular orbital (MO) theory is a method for determining molecular structure in which electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole… …
76Relaxation (approximation) — In mathematical optimization and related fields, relaxation is a modeling strategy. A relaxation is an approximation of a difficult problem by a nearby problem that is easier to solve. A solution of the relaxed problem provides information about… …
77Unified neutral theory of biodiversity — The unified neutral theory of biodiversity and biogeography (here Unified Theory or UNTB ) is a theory and the title of a monograph [http://www.pupress.princeton.edu/titles/7105.html] by ecologist Stephen Hubbell. The theory aims to explain the… …
78Pragmatic theory of truth — refers to those accounts, definitions, and theories of the concept truth that distinguish the philosophies of pragmatism and pragmaticism. The conception of truth in question varies along lines that reflect the influence of several thinkers,… …
79Wien approximation — Wien s approximation (also sometimes called Wien s law or the Wien distribution law ) is a law of physics used to describe the spectrum of thermal radiation (frequently called the blackbody function). This law was first derived by Wilhelm Wien in …
80Slow-motion approximation — In physics, the slow motion approximation is an approximation that is used in relativistic mechanics where the speed of an object under consideration is significantly less than the speed of light.The approximation is sometimes used as a… …
