Byl èlenem mnoha akademií vìd v zahranièí, od roku 1961 èestným profesorem Lomonosov ovy univerzity v Moskvì, byl jedním z nejvýznamìjších vìdcù 20. století. V roce 1922 obdržel Nobelovu cenu za výzkumy a model atomu. Pøestože o Bohrovu modelu atomu bývá v souèasných uèebnicích jen historická zmínka, nic to neubírá na významu Bohrovy teorie. Ta ve své dobì spojila dva hlavní smìry fyziky - nìmecký teoretický v èele s M. Planckem a A. Einsteinem a anglický experimentální v èele s J.J. Thomsonem a E. Rutherfordem.

Inizialmente interessato alle propriet  dei metalli, cominci² a studiare la teoria di Plank dei quanti. fisica Nel 1913 Bohr pubblic² un lavoro sull'assorbimento dei raggi alfa, ma si dedic² anche allo studio della struttura atomica, basandosi sui lavori di Rutherford, (il cui modello era in contraddizione con la fisica classica), integrandoli con la teoria di Plank dei quanti. Propose infatti che gli elettroni si muovessero su orbite stabili con energie definite e discrete attorno al nucleo atomico. Inoltre, un elettrone poteva cambiare orbita emettendo o assorbendo fotoni di energia proporzionale alla differenza di energia dei livelli. Questo divenne la base della teoria dei quanti e la contraddizione con l'approccio classico fu poi risolta dalla meccanica quantistica negli anni a venire.

But the opposite of a profound truth may well be another profound truth. Niels Bohr Niels Bohr was born on October 7, 1885 in Copenhagen, Denmark. Bohr made numerous contributions to our understanding of atomic structure and quantum mechanics. He won the 1922 Nobel Prize for physics, chiefly for his work on the structure of atoms. Bohr received his doctorate in physics from the University of Copenhagen in 1911. He then traveled to Manchester, England to study under British physicist Ernest Rutherford. In 1913 Bohr published a theory about the structure of the atom based on an earlier theory of Rutherford's. Rutherford had shown that the atom consisted of a positively charged nucleus, with negatively charged electrons in orbit around it. Bohr expanded upon this theory by proposing that electrons travel only in certain successively larger orbits. He suggested that the outer orbits could hold more electrons than the inner ones, and that these outer orbits determine the atom's chemical properties. Bohr also described the way atoms emit radiation by suggesting that when an electron jumps from an outer orbit to an inner one, that it emits light. Later other physicists expanded his theory into quantum mechanics. This theory explains the structure and actions of complex atoms. Bohr became a professor of physics at the University of Copenhagen in 1916. In 1920 Bohr was named director of the newly constructed "Institute of Theoretical Physics" at the University. Bohr became a Fellow of the Royal Society of London in 1926, receiving the Royal Society Copley Medal in 1938. During World War II, Bohr fled Copenhagen to escape the Nazis. He traveled to Los Alamos, New Mexico to advise the scientists developing the first atomic bomb. He returned to Copenhagen after the war and later promoted the peaceful use of atomic energy.

Branch of Science Physicists Nationality Danish ... Scientific Families Bohr, Niels (1885-1962) Danish physicist who proposed a successful quantum model of the atom in 1913. His model assumed that (1) the electron exists at precise distances from the nucleus, (2) as long as an electron remains in one location, no energy is given off, (3) electrons have circular orbits (this is only correct for s orbitals), and (4) the angular momenta associated with allowed electron motion are integral multiples of . Bohr stated the Correspondence Principle, which states that quantum mechanical formulas must reduce to the classical results in the limit of large quantum number.

Christian Bohr was awarded a doctorate in physiology from the University of Copenhagen in 1880 and in 1881 he became a Privatdozent at the university. Late in the same year he married Ellen, who was the daughter of David Adler, a Jewish politician with a high standing in Danish political and commercial life. Christian and Ellen had three children. The eldest was Jenny born in 1883 in the mansion which David Adler had owned opposite Christiansborg Castle where the Danish Parliament sat. Ellen's mother had continued to live in this house after her husband David Adler died in 1878 and Ellen had gone back to her mother's home to have her child. Two years later Niels was born on his mother's 25 th birthday in the same stately home, Ellen again having returned to her mother's house for the birth of her child.

40. Discussions With Einstein On Epistemological Problems In Atomic Physics Report by niels bohr of his discussions with Albert Einstein over many years on the epistemological implications of quantum theory. http://www.marxists.org/reference/subject/philosophy/works/dk/bohr.htm

Niels Bohr (1949) Discussions with Einstein on Epistemological Problems in Atomic Physics Source : From Albert Einstein: Philosopher-Scientist (1949), publ. Cambridge University Press, 1949. Neils Bohr's report of conversations with Einstein and Einstein's reply. WHEN invited by the Editor of the series, Living Philosophers With unfailing intuition Einstein thus was led step by step to the conclusion that any radiation process involves the emission or absorption of individual light quanta or "photons" with energy and momentum E hf and P hs respectively, where h is Planck's constant, while f and s are the number of vibrations per unit time and the number of waves per unit length, respectively. Notwithstanding its fertility, the idea of the photon implied a quite unforeseen dilemma, since any simple corpuscular picture of radiation would obviously be irreconcilable with interference effects, which present so essential an aspect of radiative phenomena, and which can be described only in terms of a wave picture. The acuteness of the dilemma is stressed by the fact that the interference effects offer our only means of defining the concepts of frequency and wavelength entering into the very expressions for the energy and momentum of the photon. In this situation, there could be no question of attempting a causal analysis of radiative phenomena, but only, by a combined use of the contrasting pictures, to estimate probabilities for the occurrence of the individual radiation processes. However, it is most important to realize that the recourse to probability laws under such circumstances is essentially different in aim from the familiar application of statistical considerations as practical means of accounting for the properties of mechanical systems of great structural complexity. In fact, in quantum physics we are presented not with intricacies of this kind, but with the inability of the classical frame of concepts to comprise the peculiar feature of indivisibility, or "individuality," characterising the elementary processes.
