![]() Bohr provided a rough prescription for the correspondence limit: it occurs when the quantum numbers describing the system are large. The conditions under which quantum and classical physics agree are referred to as the correspondence limit, or the classical limit. Arnold Sommerfeld referred to the principle as "Bohrs Zauberstab" (Bohr's magic wand) in 1921. Bohr's correspondence principle demands that classical physics and quantum physics give the same answer when the systems become large. ![]() If quantum mechanics were to be applicable to macroscopic objects, there must be some limit in which quantum mechanics reduces to classical mechanics. But macroscopic systems, like springs and capacitors, are accurately described by classical theories like classical mechanics and classical electrodynamics. The rules of quantum mechanics are highly successful in describing microscopic objects, atoms and elementary particles. Ĭlassical quantities appear in quantum mechanics in the form of expected values of observables, and as such the Ehrenfest theorem (which predicts the time evolution of the expected values) lends support to the correspondence principle. This concept is somewhat different from the requirement of a formal limit under which the new theory reduces to the older, thanks to the existence of a deformation parameter. The term codifies the idea that a new theory should reproduce under some conditions the results of older well-established theories in those domains where the old theories work. ![]() ![]() The principle was formulated by Niels Bohr in 1920, though he had previously made use of it as early as 1913 in developing his model of the atom. In other words, it says that for large orbits and for large energies, quantum calculations must agree with classical calculations. In physics, the correspondence principle states that the behavior of systems described by the theory of quantum mechanics (or by the old quantum theory) reproduces classical physics in the limit of large quantum numbers. There is a significant intergenerational replication of consciousness and socialized inequality via the linkages among the authority relations experienced by fathers at work, transferred to childrearing styles, and replicated in school interaction with teachers.For other uses, see Correspondence principle (disambiguation). They also emphasize that there is a strong relationship between the child’s education and the interaction they have with their parents at home. ![]() Apart from the formal curriculum that is offered by the school, the advocates of the correspondence principle argue that the structure of the school and also the personal experience given to each student (the hidden curriculum) is important to their future socialization. In its most basic form the principle states that the social relations of the school can be directly related to those in the work-place, meaning that educational institutions prepare students for their future work roles. 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. The correspondence principle or correspondence thesis is a sociological theory that posits a close relationship between social standing and the educational system. ![]()
