Birth Date
The day that Niels Bohr was born. -
School
Niels Bohr entered the University of Copenhagen where he was under the guidance of Professor C. Christiansen. -
Degree
He got a Masters degree in phyics. -
Degree
Later got a Doctorates Degree. -
Marriage
Professor Bohr was married, in 1912, to Margrethe Nørlund, who was for him an ideal companion. They had six sons, of whom they lost two; the other four have made distinguished careers in various professions – Hans Henrik (M.D.), Erik (chemical engineer), Aage (Ph.D., theoretical physicist, following his father as Director of the Institute for Theoretical Physics), Ernest (lawyer). -
Contribution
Bohr developed and published his model of atomic structure known as the Bohr Model, He also introduced that atoms travel in discrete orbits around the atoms nucleus. Also proposed that an electron can drop from a higher energy orbit to a lower one. -
Job At Copenhagen
He was appointed the professor of theoretical physics at Copenhagen university. -
Award
For his recognition of his work on the structure of atoms he received A Nobel Prize for his findings. -
Assistant
Werner Heisenberg worked as Bohr’s assistant at the Institute from 1926 to 1927, and the two men worked closely on the mathematical foundations of quantum mechanics. It was during this fertile period in Copenhagen that Heisenberg developed his famous uncertainty principle. -
Assistant Cont.
It was also during this period that Bohr developed his principle of complementarity, the idea that that particles could be separately analyzed as having several contradictory, and apparently mutually exclusive, properties (an example being the wave-particle duality of light, where light can either behave as a particle or as wave, but not simultaneously as both). -
WW2
Bohr escaped to Sweden and spent the last two years of the war in England and America, where he became associated with the Atomic Energy Project. -
Peace Between Nations
In his later years, he devoted his work to the peaceful application of atomic physics and to political problems arising from the development of atomic weapons. In particular, he advocated a development towards full openness between nations. His views are especially set forth in his Open Letter to the United Nations -
Death Date
Niels Bohr Died at the age of 77 and was buried in Copenhagen.
