Niels Henrik David Bohr The Danish physicist Niels Henrik David Bohr, b. Oct. 7, 1885, d. Nov. 18, 1962, is known primarily for his pioneering work in the field of atomic theory. Bohr was born in Copenhagen and was educated at the University of Copenhagen at the time when Max Planck had just begun the development of quantum mechanics. After completing his dissertation on the electron theory of metals in 1911, Bohr went briefly to Cambridge and then on to Manchester, England. There he worked under Ernest Rutherford, who in 1911 had published the theory that the atom consisted of a central nucleus orbited by electrons. The problem with this model was that, according to classical electrodynamic theory, the electrons should radiate and therefore lose energy and spiral into the nucleus. With the problem of atomic structure in mind, Bohr worked in Manchester relentlessly from May through July of 1912 and succeeded in obtaining a formula correctly describing the absorption of helium nuclei by other atomic nuclei. His guiding notion was that the energy lost by a helium nucleus in flying through an atom depends not on the size of the atom but rather on the distances between the nucleus and the various electrons in the atom. In 1916, Bohr was appointed professor of theoretical physics at the University of Copenhagen, and in 1922 he was awarded the Nobel Prize for physics. In the following decades he continued to work on the implications of his theory, notably putting an earlier knowledge of surface tension to use in his "droplet model" of the nucleus, which treats the nucleus as if it were a water droplet held together by its surface tension.

Niels Bohr Danish Physicist and the leader of the Copenhagen School of the (interpretation of) quanum mechanics, which makes "complementarity" the key word. The complementarity is a difficult concept, but it means something like this: the conservation law and the description in terms of space and time are both necessary in physics, but they become incompatible in quantum physics and they become complementary. Thus two features are complementary if both are indispensable but the two are incompatible in one and the same description. Aside from his professional contributions to physics such as atomic models (1913), he played an essential role for the development of quantum physics, as the leader of the Niels Bohr Institute (1921-) of the University of Copenhagen. Such great figures as Pauli and Heisenberg produced their works in a free and lively atmosphere of this Institute; and many first-rate physicists all over the world visited there. As regards the defence of quantum mechanics, he had a long controversy with Einstein. His Institute also played an important role for saving many exile scientists from Germany and other countries. However, Bohr himself was forced to exile himself to the Britain.

He studied at the Univ. of Copenhagen (Ph.D. 1911) and carried on research on the structure of the atom at Cambridge under Sir James J. Thomson and at Manchester under Lord Ernest Rutherford. In 1916, Bohr became professor of theoretical physics at the Univ. of Copenhagen, and in 1920 he was made director of the Institute of Theoretical Physics, which he was instrumental in founding. Rutherford had discovered the nucleus of the atom in 1911, but classical theory was unable to explain the stability of the nuclear model of the atom. Bohr provided the solution to this problem in 1913, when he postulated that electrons move around the nucleus of the atom in restricted orbits and explained the manner in which the atom absorbs and emits energy. He thus combined the quantum theory with this concept of atomic structure. Much of the knowledge of modern physics was made possible by Bohr's initial revolutionary assumption that atomic processes cannot be explained by classical laws alone. Bohr was a leading figure in the continuing development of the quantum theory over the next twenty years. He received the 1922 Nobel Prize in Physics.

It enables physicists, chemists, and technicians to calculate and predict the outcome of a vast number of experiments and to create new and advanced technology based on the insight into the behavior of atomic objects. But it is also a theory that challenges our imagination. It seems to violate some fundamental principles of classical physics, principles that eventually have become a part of western common sense since the rise of the modern worldview in the Renaissance. So the aim of any metaphysical interpretation of quantum mechanics is to account for these violations. The Copenhagen interpretation was the first general attempt to understand the world of atoms as this is represented by quantum mechanics. The founding father was mainly the Danish physicist Niels Bohr, but also Werner Heisenberg, Max Born and other physicists made important contributions to the overall understanding of the atomic world that is associated with the name of the capital of Denmark.

Bohr, Niels (Henrik David) Danish physicist. His theoretical work produced a new model of atomic structure, now called the Bohr model, and helped establish the validity of quantum theory. He also explained the process of nuclear fission. Nobel Prize for Physics 1922. Bohr's first model of the atom was developed working with Ernest Rutherford at Manchester, UK. He was director of the Institute of Theoretical Physics in Copenhagen from 1920. During World War II he took part in work on the atomic bomb in the USA. In 1952 he helped to set up CERN, the European nuclear research organization in Geneva. He proposed the doctrine of complementarity: that a fundamental particle is neither a wave nor a particle, because these are complementary modes of description. Bohr was born and educated in Copenhagen. In 1911 he went to the UK to study at the Cambridge atomic-research laboratory under J J Thomson, but moved 1912 to Manchester to work with New Zealand physicist Rutherford. Bohr developed models of the atom in which electrons are disposed in rings around the nucleus, a first step towards an explanation of atomic structure. In 1913 Bohr developed his theory of atomic structure by applying quantum theory to the observations of radiation emitted by atoms. The authorities in Denmark made him a professor 1916 and then built the Institute of Theoretical Physics for him. Leading physicists from all over the world developed Bohr's work there, resulting in the theories of quantum and wave mechanics that more fully explain the behaviour of electrons within atoms. Bohr's atomic theory was validated 1922 by the discovery of an element he had predicted, which was given the name hafnium.
