		Bohr knew that the electrons should, theoretically, lose energy and spiral toward the nucleus until they collide with it.
		Bohr’s model of the atom proved essentially correct, and he won the Nobel Prize for his quantum theory studies in 1922.
		Bohr came up with “complementarity.” This is also called wave-particle duality, which states that certain waves, like light, exhibit characteristics of waves and particles.

	The Bohr Atom
		Bohr concluded that in an atom in its natural rest state, the electron must be in a special orbit, he called it a "stationary state" to which the usual rules of electromagnetic radiation didn't apply.
		Bohr suggested in a note to Rutherford in the summer of 1912 that requiring this energy be some constant (assumed to be of order of magnitude one) multiplied by hf would fix the size of the atom.
		Therefore, Bohr concluded K is fixed by requiring that the frequency of radiation emitted by a really large atom be correctly given by ordinary common sense -- that is, the frequency of the radiation must be the same as the orbital frequency of the electron, the number of cycles a second.

	Niels Bohr Birthday
		Niels Henrik David Bohr was born in Copenhagen, Denmark on October 7, 1885 to Christian Bohr, a professor of physiology at Copenhagen University, and Ellen Bohr, also known as Adler.
		Bohr was among the first to see the importance of atomic number, which indicates the position of an element on the periodic table and is equal to the number of protons in the nuclei of atoms.
		Bohr also recognized that the various physical and chemical properties of the elements depend upon the electrons moving around the nuclei of atoms.

		Bohr did most of his original work as a young man. By the time he reached middle age he was doing some original work, but his best work was done in collaboration with young physicists who came and worked with him in Copenhagen.
		Bohr postulated that radiation is emitted from atoms not as a result of the periodic motion of the electron in its orbit, but only when an electron "jumps" from one orbit to another losing energy that is emitted as radiation.
		Bohr's theory of the compound nucleus, in which the repulsion between positively charged protons is countered by huge amounts of energy in order to hold the nucleus together, helped lead to the hypothesis that splitting an atom would produce enough energy to fabricate a powerful weapon.

	From Bohr's Atom to Electron Waves
		Bohr's interpretation of the Balmer formula in terms of quantized angular momentum was certainly impressive, but his atomic model didn't make much mechanical sense, as he himself conceded.
		Harald Bohr wrote to his brother from Göttingen in the fall of 1913 that the young physicists there considered Bohr's model too "bold" and "fantastic".
		It was also good evidence that Bohr's theory was close to correct for the innermost electrons in the atom, those in the field of the unshielded nucleus.

	Harald Bohr correspondence
		Harald Bohr Papers in Copenhagen is a very tiny fraction of the large amount of letters to and from Bohr which once existed.
		Bohr writes about his participation in a meeting in Innsbruck (1924), displaced German mathematicians (1933-34), the Scandinavian congresses of mathematicians in Copenhagen (1946) and Trondheim (1949), Carl L. Siegel and Helen Braun's stay in Denmark (1947) and the attempt to create a professorship in Norway to keep Atle Selberg there.
		The correspondence after 1945 is in English and kept in the Harald Bohr Archive Correspondence Folder, in the archival Courant file cabinets, Courant Institute of Mathematical Sciences, New York (not in the library).

	The Niels Bohr Archive
		The Niels Bohr Archive (NBA) holds primary material for the history of modern physics, pertaining in particular to the early development of quantum mechanics and the life and career of Niels Bohr (1885-1962).
		Although the NBA has existed since shortly after Bohr's death in 1962, its future was only secured at the centennial of Bohr's birth in 1985, when a deed of gift from Bohr’s wife, Margrethe, provided the opportunity to establish the NBA as an independent not-for-profit institution.
		Thus, in 1985 the Bohr family donated the bulk of Bohr's private correspondence, which includes letters to and from central personalities in culture and politics inside and outside Denmark.
