The Niels Bohr Institute in Copenhagen. The 'Copenhagen' part of the term refers to the city of Copenhagen in Denmark. During the mid-1920s, Heisenberg had been an assistant to Bohr at his institute in Copenhagen. Together they helped originate quantum mechanical theory.
Niels Henrik David Bohr (7 October 1885 – 18 November 1962) was a Danish theoretical physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.
The definition of quantum theorists' terms, such as wave function and matrix mechanics, progressed through many stages.For instance, Erwin Schrödinger originally viewed the electron's wave function as its charge density smeared across space, but Max Born reinterpreted the absolute square value of the wave function as the electron's probability density distributed across space; [3]: 24–33 ...
A study of the painful three-way relationship between Hugh Everett, John A Wheeler and Niels Bohr and how this affected the early development of the many-worlds theory. David Wallace, Worlds in the Everett Interpretation, Studies in History and Philosophy of Modern Physics , 33, (2002), pp. 637–661, arXiv : quant-ph/0103092
Niels Bohr never mentions wave function collapse in his published work, but he repeatedly cautioned that we must give up a "pictorial representation". Despite the differences between Bohr and Heisenberg, their views are often grouped together as the "Copenhagen interpretation", of which wave function collapse is regarded as a key feature. [19]
Niels Bohr's 1913 quantum model of the hydrogen atom. In 1913 Niels Bohr proposed a new model of the atom that included quantized electron orbits: electrons still orbit the nucleus much as planets orbit around the Sun, but they are permitted to inhabit only certain orbits, not to orbit at any arbitrary distance.

It illustrates the counter-intuitive implications of Bohr's Copenhagen interpretation when applied to everyday objects. [ 1 ] A thought experiment is a hypothetical situation in which a hypothesis , theory , [ a ] or principle is laid out for the purpose of thinking through its consequences.
The initial idea of the BKS theory originated with Slater, [13] who proposed to Bohr and Kramers the following elements of a theory of emission and absorption of radiation by atoms, to be developed during his stay in Copenhagen: Emission and absorption of electromagnetic radiation by matter is realized in agreement with Einstein's photon concept;
