Niels Bohr (October 7, 1885 - November 18, 1962)
Born in Copenhagen, Denmark with a complete name of Niels Henrik David Bohr. -
Bohr Atomic Model
Bohr's atomic model shows that electrons can only occupy specific orbital. His atomic model was able to start the spectral line series that was emitted by hydrogen. The model also showed that electromagnetic radiation from an atom occurred only when an electron jumped to a lower-energy orbit. -
Bohr’s Institute for Theoretical Physics
Following his career as a theoretical Physics professor in the University of Copenhagen, Bohr established an Institute for Theoretical Physics. He focused on making the institute a place where the new generation of physicists can propose new ideas. To support that he made the experimenters and experiments indispensable in order to promote testing theorist's statements. -
Nobel Prize
Bohr was awarded the Nobel Prize in Physics for investigating the structure of atoms and the radiation editing from them. -
Bohr's Philosophy of Free Choice
Bohr's philosophy of Free choice states that, " if the position is measured accurately, the (complementary conjugate and non-commuting variable) momentum is necessarily (sic) indeterminate". This translates that the freedom of which a specific property to measure for is in the scientist's hands. Opposing Albert Einstein's claim in EPR paradox that, "quantum mechanics requires the addition of further parameters or hidden variables to restore a deterministic picture of the elements of reality." -

Bohr and Nuclear Physics
Bohr with the help of August Krogh and Hevesy applied for support to build a cyclotron that was invented by Ernest Lawrence. Tahe cyclotron acts as a particle accelerator which Bohr used to investigate nuclear physics. The cyclotron produced isotopes of elements and extended the radioactive indicator method. -
Bohr and atomic bomb
Bohr willingly joins the Allied project after escaping the Nazis in Sweden. Bohr made significant contributions such as the design of the plutonium bomb initiator. According to J. Robert Oppenheimer, Bohr's most important role in the atomic bomb development was being a "scientific father confessor to the younger men.” -
Bohr Post Exile
Bohr was able to return home in Denmark after the atomic bomb was dropped. He expanded his institute and continued to ran it. He played a part in the establishment of Conseil Européen pour la Recherche Nucléaire", or European Council for Nuclear Research aka CERN. He also took part in the establishment of the Nordic Institute for Atomic Physics. -
Bohr's Death
Died in his home in Copenhagen following a stroke -
