- Bohr, Niels Henrik David 1885-1962. Danish physicist. He won a 1922 Nobel Prize for investigating atomic structure and radiations. His son Aage Niels Bohr (born 1922), also a physicist, shared a 1975 Nobel Prize for discovering the asymmetry of atomic nuclei.
- n. Danish physicist who studied atomic structure and radiations; the Bohr theory of the atom accounted for the spectrum of hydrogen (1885-1962)
“What serves in Bohr's theory as a basis to build up the laws of action, is assembled out of specific hypotheses which, up to a generation ago, would undoubtedly have been flatly rejected altogether by every physicist.”
“It came as a result of his dissatisfaction with the quantum condition in Bohr's orbit theory and his belief that atomic spectra should really be determined by some kind of eigenvalue problem.”
“In a similar manner Bohr is able, with the help of the principle of correspondence, to establish, in the most important points, the situation of the various tracks of electrons in other atoms.”
“In quantum theory (in Bohr’s interpretation), this termination takes place at the level of the ultimate constituents of matter, usually identified with elementary "particles.”
“In quantum mechanics (at least in Bohr’s interpretation, which I follow here) such an underlying order and, ultimately, any conceivable "bottom" configuration cannot be assumed in principle, which impossibility, however, enables the consistently configured possibility of radical organization at the manifest level.”
“While both visions just described may be juxtaposed to classical physics (including classical statistical physics, the classical understanding of chance), the first, allegorical, vision corresponds roughly to that of quantum physics, especially in Bohr’s interpretation (there are more classical-like, realist and causal interpretation and versions of quantum mechanics); the second to that of chaos theory.

“The latter entails a particular form of epistemology, correlative to the epistemology of quantum physics, specifically in Bohr’s interpretation, known as "complementarity," which I would argue to be the most radical among a host of available interpretations and which I shall follow here.”
“The importance of Bohr's role in providing guidance to others 'research had soon become widely recognized, as can be seen, for example, by the following lines found20 in the New York Times in 1924: "Working with Dr. Bohr is regarded by scientists as working with the foremost of the exponents of the new atomic physics, which is revolutionizing science.”
“The discovery became known as the Bohr effect but was based entirely on equipment that Krogh had designed, which made it possible to measure the oxygen-binding capacity of blood.”
“It was suggested by the American physicist Breit that the reason for this could be that the magnetic moment of the electron is somewhat different from the value assumed until then which is called a Bohr magneton.”
