• Niels Bohr, there is often some confusion concerning both what the Copenhagen interpretation precisely amounts to, and which parts of this interpretation are associated with whom of the founding figures of quantum mechanics. But there are signs that the mist is beginning to clear up. For instance, Howard (2004) convincingly argues that.

Executive summary: Father of Quantum Theory

Danish physicist Niels Bohr studied under J. J. Thomson, who discouraged his ideas, and under Ernest Rutherford, whose work was expanded by Bohr into a new theory on the structure of the atom in 1913. Bohr postulated that electrons travel in fixed orbits around the atom's nucleus, and further explained how electrons emit or absorb energy, work that earned him the Nobel Prize in Physics in 1922. Bohr's atomic diagram held that the outer orbits hold more electrons than inner orbits, that atoms traveling from one orbit to another emit tiny amounts of radiation, and that these orbits determine chemical properties of an atom.

Bohr's theory, elaborated and expanded by other physicists, formed the basis for the developing science of quantum mechanics. He is best known for two concepts — the correspondence principle, and the complementarity principle. The former holds that to untangle the contradictions between 'old' and 'new' physics, new theories must both describe atomic phenomena correctly and be applicable to conventional phenomena; the latter holds that wave and particle aspects of nature are complementary and can never both be true simultaneously.

Niels Bohr Model

Though raised and baptized a Christian, his mother was Jewish, and Bohr fled Denmark during World War II, coming to America, where he worked on the Manhattan Project. After the war he became an outspoken activist against nuclear weapons and for the peaceful use of atomic energy. He was also a co-founder of the European Organization for Nuclear Research (CERN).

Bohr's brother, mathematician Harald August Bohr (1887-1951), developed a theory of 'almost periodic' functions, and won a Silver Medal playing soccer for the Danish national team in the 1908 Olympics. Niels Bohr's son, Aage N. Bohr, won the Nobel Prize in Physics in 1975 for describing the collective model of the atomic nucleus.
