Basic facts Practical information History Key events ... The vikings Niels Bohr Niels Bohr, the 1922 Nobel Prize Winner in physics, was born in Copenhagen in 1885. While at Copenhagen University Bohr calculated the basics of atomic structure and went on to formulate the principle of atomic fission, crucial to the development of the atom bomb. He won the Nobel Prize for his work of explaining the periodic system of elements, and how it relates to the atomic structure. Bohr was one of the thousands of Jews who escaped Nazi occupation in 1943, travelling via Sweden to the US. While in exile there he worked together with Einstein, among others, on the construction of the first atom bomb, though he later campaigned against its use, publishing an open letter to the United Nations in 1950 asking for international co-operation on nuclear weapon development. back print page top

21st Century Masters Niels Bohr Niels Bohr was born on October 7, 1885 in Copenhagen, Denmark. Bohr made numerous contributions to our understanding of atomic structure and quantum mechanics. He won the 1922 Nobel Prize for physics, chiefly for his work on the structure of atoms. Bohr received his doctorate in physics from the University of Copenhagen in 1911. He then traveled to Manchester, England to study under British physicist Ernest Rutherford. In 1913 Bohr published a theory about the structure of the atom based on an earlier theory of Rutherford's. Rutherford had shown that the atom consisted of a positively charged nucleus, with negatively charged electrons in orbit around it. Bohr expanded upon this theory by proposing that electrons travel only in certain successively larger orbits. He suggested that the outer orbits could hold more electrons than the inner ones, and that these outer orbits determine the atom's chemical properties. Bohr also described the way atoms emit radiation by suggesting that when an electron jumps from an outer orbit to an inner one, that it emits light. Later other physicists expanded his theory into quantum mechanics. This theory explains the structure and actions of complex atoms. Bohr became a professor of physics at the University of Copenhagen in 1916. In 1920 Bohr was named director of the newly constructed "Institute of Theoretical Physics" at the University. Bohr became a Fellow of the Royal Society of London in 1926, receiving the Royal Society Copley Medal in 1938. During World War II, Bohr fled Copenhagen to escape the Nazis. He traveled to Los Alamos, New Mexico to advise the scientists developing the first atomic bomb. He returned to Copenhagen after the war and later promoted the peaceful use of atomic energy.

Niels Bohr Niels Henrik David Bohr, a Danish physicist and Nobel laureate, made basic contributions to nuclear physics and the understanding of atomic structure. Bohr's theory of atomic structure, 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. Bohr's atomic model made use of quantum theory and the Planck constant (the ratio between quantum size and radiation frequency). The model suggested 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 went 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. In 1939, recognizing the significance of the fission experiments of the German scientists Otto Hahn and Fritz Strassmann, Bohr convinced physicists at a scientific conference in the U.S. of the importance of those experiments. He later demonstrated that uranium-235 is the particular isotope of uranium that undergoes nuclear fission. Bohr then returned to Denmark, where he was forced to remain after the German occupation of the country in 1940. Eventually, however, he was able to escape to Sweden, under peril of his life and that of his family. From Sweden the Bohrs traveled to England and eventually to the United States, where Bohr joined in the effort to develop the first atomic bomb, working at Los Alamos, New Mexico, until the first bomb's detonation in 1945. He opposed complete secrecy of the project, however, and feared the consequences of this ominous new development. He desired international control.

WHAT'S MY STYLE Niels Bohr Profile: Scintillator Evokateur Visionary Profile Boss: Evokateur Why Scintillator Niels displayed great talent with his hands and was able to take apart and put together mechanical things when he was very young. Studied physics, played soccer. Good sense of humor: Never express yourself more clearly than you can think. The Niels Bohr stamp from Denmark An expert is a man who has made all the mistakes which can be made, in a very narrow field. When it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images. There are some things so serious you have to laugh at them. It is wrong to think that the task of physics is to find out how Nature is. Physics concerns what we say about Nature. Niels closed most public speeches with stories to end on a humorous note but that further drove his point home: "One of our neighbors in Tisvilde once fixed a horseshoe over the door to his house. When a common friend asked him, `But are you really superstitious? Do you honestly believe that this horseshoe will bring you luck?' he replied, `Of course not; but they say it works even if you don't believe in it.'" Why Evokateur Lived, worked, and died in Copenhagen Denmark. Nobel Prize for Physics in 1922. Donated his gold Nobel medal to the Finnish war effort . After German occupation of Denmark, and because he was Jewish and because he refused to do research for Germany, he traveled to Los Alamos, New Mexico to advise the scientists developing the first atomic bomb (US Manhattan Project) . He returned to Copenhagen after the war.

Visit the Molecular Expressions Website Galleria Photo Gallery ... Home Niels Henrik David Bohr Renowned physicist and Nobel Prize laureate Niels Henrik David Bohr was born on October 7, 1885 in Copenhagen, Denmark. His mother hailed from a wealthy Jewish banking family and his father was a physiology professor at the University of Copenhagen. Bohr had two siblings, one of which, Harald Bohr, would later become a distinguished mathematician. During his childhood, Bohr was already demonstrating a penchant for understanding how things work, often fixing instruments, such as clocks, that needed repair. He excelled in his studies and graduated from high school in 1903. He was then accepted at the University of Copenhagen and there embarked on an impressive academic career in physics. Bohr's thesis concerning the determination of surface tension through vibrations of water jets garnered him a gold medal from the Royal Danish Academy of Science in 1907. After graduation that same year, he decided to stay on to pursue his Masters, which he received in 1909, and his doctorate, awarded in 1911. Bohr, primarily interested in electromagnetism and atomic theory, was awarded a travel grant by the Carlsberg Foundation in 1911. He planned to spend a year at the Cavendish Laboratory at Cambridge for research, but only stayed for a brief period since the director at the time, J.J. Thomson, did not express interest in his ideas. Though discouraged by Thomson, Bohr caught the attention of another physicist, Ernest Rutherford, and traveled to Manchester in 1912 to participate in the construction of his nuclear model of the atom. There he began the work that would dominate his career, but returned to Copenhagen that summer as scheduled, soon marrying Margrethe Norlund, with whom he would later have four sons.

Bohr, Niels Henrik David (Copenaghen 1885-1962), fisico danese. Figlio di un professore di fisiologia, studiò all'Università di Copenaghen, dove si laureò nel 1911. Si recò poi all'Università di Cambridge per studiare fisica nucleare sotto la guida di Joseph John Thomson, ma ben presto si trasferì a Manchester dove iniziò a collaborare con Ernest Rutherford. La teoria della struttura atomica di Bohr, per la quale fu insignito del premio Nobel per la fisica nel 1922, venne formulata in tre memorie pubblicate tra il 1913 e il 1915. I suoi studi erano basati sul modello atomico di Rutherford, secondo il quale l'atomo è costituito da un nucleo compatto circondato da elettroni, molto più leggeri. Il modello proposto da Bohr prevede che gli elettroni siano disposti intorno al nucleo su orbite stabili, corrispondenti a livelli energetici ben definiti, e che l'emissione o l'assorbimento di radiazione elettromagnetica si verifichi a seguito di transizioni elettroniche tra livelli quantici diversi. Inoltre, le proprietà chimiche dell'atomo sono determinate dal numero di elettroni che occupano il livello energetico più esterno. Nel 1916 Bohr tornò all'Università di Copenaghen in qualità di professore di fisica, e nel 1920 divenne direttore dell'Istituto di fisica teorica. Qui si dedicò allo studio dei fondamenti della meccanica quantistica, ponendo alla base del suo lavoro il cosiddetto principio di corrispondenza, secondo cui la teoria dei quanti deve fornire gli stessi risultati della fisica classica per sistemi di dimensioni macroscopiche.

I read the examination question: "'Show how it is possible to determine the height of a tall building with the aid of a barometer.' "The student had answered: 'Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope [which is] the height of the building.'

History top Home Historical Notes Bohr, Niels Henrik David Danish physicist, Nobel Prizewinner 1922 for theory of the hydrogen atom Born: Copenhagen, October 7, 1885 Died: Copenhagen, November 18, 1962 Einstein: " God does not play dice. Einstein: " God is not malicious. Bohr: " Einstein, stop telling God what to do. One of the most sparkling and prolonged scientific jousting matches took place between Niels Bohr and Albert Einstein in the 20s and 30s. The latter, who could never accept the probabilistic nature of quantum mechanics, produced a series of gedanken experiments (thought experiments) designed to disprove the new theory. Bohr would then attempt to show where Einstein had gone wrong. In one of Bohr's successful attempts at this, he was especially pleased to note that Einstein had forgotten that according to his own theory of general relativity clocks run more slowly under the influence of a gravitational field. In terms of scientific brilliance Niels Bohr is right at the top, perhaps second only to Einstein in the hit parade of 20th century scientists. It seems that every scientist who met Bohr came away with an impression of his deep intellect and his kind, gentle manner. (The phrase "large domed head" seems to occur frequently, too.) Bohr lies at the end of a list of philosopher/scientists which charts the establishment of atomism in the scientific canon over the centuries: from the pre-Socratics Democritus and Leucippus;to Epicurus and Lucretius; to Dalton who was the first to create the concept of atoms in a modern scientific format; to Rutherford and Geiger who demonstrated the nuclear structure of the atom; to Bohr who was able to unite Rutherford's atom with the quantum concept of Planck.
