The correspondence principle or correspondence thesis is a sociological theory that posits a close relationship between social standing and the educational system. Writers in this vein (notably Gary Watson and Diep Tran) are in particular interested in the relationship between a person’s social standing and the type of education that is received at school.
In physics, a correspondence principle is any one of several premises or assertions about the relationship between classical and quantum mechanics.The physicist Niels Bohr coined the term in 1920 [1] during the early development of quantum theory; he used it to explain how quantized classical orbitals connect to quantum radiation. [2]
According to the correspondence principle, in certain limits the quantum equations of states must approach Hamilton's equations of motion.The latter state the following relation between the generalized coordinate q (e.g. position) and the generalized momentum p: {˙ = = {,}; ˙ = = {,}.
Correspondence theory is a traditional model which goes back at least to some of the ancient Greek philosophers such as Plato and Aristotle. [2] [3] This class of theories holds that the truth or the falsity of a representation is determined solely by how it relates to a reality; that is, by whether it accurately describes that reality.
In theoretical physics, the anti-de Sitter/conformal field theory correspondence (frequently abbreviated as AdS/CFT) is a conjectured relationship between two kinds of physical theories. On one side are anti-de Sitter spaces (AdS) that are used in theories of quantum gravity , formulated in terms of string theory or M-theory .
The correspondence theory of truth states that truth consists in correspondence with reality. [7] Or in the words of Thomas Aquinas: "A judgment is said to be true when it conforms to the external reality". [14] Truthmaker theory is closely related to correspondence theory; some authors see it as a modern version of correspondence theory. [15]
The correspondence principle is a concept in quantum theory and relativity. Correspondence principle may also refer to: Correspondence principle (sociology), correspondence between social class and available education; In public finance, the principle that identifies the places where it is beneficial to provide public goods and services
Nevertheless, as explained in the introduction, for states that are highly localized in space, the expected position and momentum will approximately follow classical trajectories, which may be understood as an instance of the correspondence principle. Similarly, we can obtain the instantaneous change in the position expectation value.
