The generalized principle applies correspondence across aspects of a complete theory, not just a single formula as in the classical limit correspondence. [ 16 ] : 17 For example, Albert Einstein in his 1905 work on relativity noted that classical mechanics relied on Galilean relativity while electromagnetism did not, and yet both work well.
A heuristic postulate called the correspondence principle was introduced to quantum theory by Niels Bohr: in effect it states that some kind of continuity argument should apply to the classical limit of quantum systems as the value of the Planck constant normalized by the action of these systems becomes very small.
Correspondence principle (physics): quantum physics theories must agree with classical physics theories when applied to large quantum numbers; Correspondence principle (sociology), the relationship between social class and available education; Correspondence problem (computer vision), finding depth information in stereography
The correspondence principle is broadly aligned with the conflict theory approach to sociology, which originated with Karl Marx.Marx's said that there is a social class division in capitalist society, between on the one hand a small percentage of the population who are capitalists, owning the means of production, and on the other workers, who sell their labor power to the capitalists.
Niels Henrik David Bohr was born in Copenhagen, Denmark, on 7 October 1885, the second of three children of Christian Bohr, [1] [2] a professor of physiology at the University of Copenhagen, and his wife Ellen née Adler, who came from a wealthy Jewish banking family. [3]

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.
In 1913, Niels Bohr displayed rudiments of the later defined correspondence principle and used it to formulate a model of the hydrogen atom which explained its line spectrum. In the next few years Arnold Sommerfeld extended the quantum rule to arbitrary integrable systems making use of the principle of adiabatic invariance of the quantum ...
