He pioneered quantum theory by showing that the nuclei of atoms are surrounded by shells of electrons, each assigned particular sets of quantum numbers according to their orbits. He explained the structure and behaviour of the nucleus, as well as the process of nuclear fission . Bohr also proposed the doctrine of complementarity , the theory that a fundamental particle is neither a wave nor a particle, because these are complementary modes of description.

It was not, however, understood how electrons could continually orbit the nucleus without radiating energy, as classical physics demanded. In 1913, Bohr developed his theory of atomic structure by applying quantum theory to the observations of radiation emitted by atoms. Ten years earlier, Max Planck had proposed that radiation is emitted or absorbed by atoms in discrete units, or

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.

Niels Bohr Memorial Bohr, Niels Henrik David (1885-1962), Danish physicist and Nobel laureate, who made basic contributions to nuclear physics and the understanding of atomic structure. Bohr was born in Copenhagen on October 7, 1885, the son of a physiology professor, and was educated at the University of Copenhagen, where he earned his doctorate in 1911. That same year he went to Cambridge, England, to study nuclear physics under the British physicist Sir Joseph John Thomson, but he soon moved to Manchester to work with Ernest Rutherford. Bohr's theory of atomic structure (see Quantum Theory), for which he received the Nobel Prize in physics in 1922, was published in papers between 1913 and 1915. His work drew on Rutherford's nuclear model of the atom, in which the atom is seen as a compact nucleus surrounded by a swarm of much lighter electrons (see Atom and Atomic Theory). Bohr's atomic model made use of quantum theory and the Planck constant (the ratio between quantum size and radiation frequency). The model posits that an atom emits electromagnetic radiation only when an electron in the atom jumps from one quantum level to another. This model contributed enormously to future developments of theoretical atomic physics. In 1916 Bohr returned to the University of Copenhagen as a professor of physics, and in 1920 he was made director of the university's newly formed Institute for Theoretical Physics. There Bohr developed a theory relating quantum numbers to large systems that follow classical laws, and made other major contributions to theoretical physics. His work helped lead to the concept that electrons exist in shells and that the electrons in the outermost shell determine an atom's chemical properties. He also served as a visiting professor at many universities.

Niels Bohr Danmark i tal Færøerne Føtex' opstartsfase ... Musik Danmark - Niels Bohr Med Niels Bohrs død i 1962 ophørte en epoke i dansk åndsliv. Ikke alene var han en af tidernes mest navnkundige danskere, men selv den dag i dag anses han som værende en af verdenshistoriens mest betydningsfulde videnskabsmænd. Ungdommen Niels Bohr blev født i København den 7. oktober 1885. Faderen var den internationalt anerkendte fysiolog Christian Bohr. Det gjorde, at hjemmet ofte besøgtes af kulturpersonligheder og forskere fra mange forskellige videnskabsgrene. Dermed havde Niels en opvækst i et intellektuelt stimulerende miljø. Vigtig for Niels var ligeledes den to år yngre bror, Harald. I voksenlivet blev lillebroderen en anerkendt matematiker, og gennem hele livet havde han en væsentlig indflydelse på storebroderens virke. Brødrene begrænsede sig imidlertid ikke til åndens arbejde. Begge spillede de fodbold. Således var Niels i 1905 målmand på AB's førstehold. For Harald gik det endda endnu bedre, han kom på landsholdet, og var ved Londons olympiske lege i 1908 med til at bringe en sølvmedalje med hjem til Danmark. Efter afsluttet studentereksamen i 1903 påbegyndte Niels Bohr fysikstudiet ved Københavns Universitet. I 1909 blev han mag.scient, hvorefter han straks gik i gang med sin doktordisputats. Denne forsvarede han to år senere.

Famous Quotes By: Bohr, Niels 1885-1962 Danish Physicist An expert is someone who knows some of the worst mistakes, which can be made, in a very narrow field. Bohr, Niels Experts Prediction is very difficult, especially about the future. Bohr, Niels Prediction Technology has advanced more in the last thirty years than in the previous two thousand. The exponential increase in advancement will only continue. Anthropological Commentary The opposite of a trivial truth is false; the opposite of a great truth is also true. Bohr, Niels Technology If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them. Bohr, Niels Science and Scientists The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth. Bohr, Niels Truth There are trivial truths and the great truths. The opposite of a trivial truth is plainly false. The opposite of a great truth is also true. Bohr, Niels Truth Never express yourself more clearly than you are able to think.

Bohr, Niels (1885-1962) Danish physicist. He is one of the most influential scientists of the twentieth century. He was the founder of atomic quantum theory and the Copenhagen interpretation of quantum physics. His theory denied the possibility of a unified, observer-independent field. His own interpretation, the heart of his Copenhagen philosophy, implies that quantum phenomena can only be described by pairs of complimentary perspectives. Though it is impossible to apply either perspective to the phenomena simultaneously, both are required for the exhaustive description of the event. Bohr desired that his methodology be applied to other spheres of knowledge - put simply, he believed that new epistemological insights are obtained by adjoining seemingly incompatible viewpoints. The Copenhagen interpretation was later developed in the work of the German physicist, Werner Heisenberg .
