In 1903 Bohr was registered as a student at the University of Copenhagen in the first study of philosophy and mathematics. In 1905, driven by competition, sponsored by the gold medal at the Danish Royal Academy of Arts and Sciences, made a series of experiments to investigate the surface properties, using his father's laboratory on campus, known for childcare. Won the essay, and this success is that Bohr had decided to approve leave philosophy and physics. As a student of Christian Christiansen received his doctorate in 1911. As a doctoral student, Bohr first experiment was JJ Thomson, Trinity College, Cambridge. Then he went to study with Ernest Rutherford at the University of Manchester in England. Based on the theory of Rutherford, Bohr model of atomic structure published in 1913 introduced the theory of electrons traveling in orbits around the nucleus, the chemical properties of elements determined above number of electrons in the outer lane. Bohr introduced the idea that the electron can fall from orbit of the highest image of lower energy beams (like light) of discrete energy. This became the basis for quantum theory.
Bohr Niels Bohr and his wife Margaret Norlund had six children. Most died in a tragic accident navigation, and others died of meningitis in children. Others will be successful life, including Aage Bohr, who later became very successful and physically with his father, the Nobel Prize for Physics in 1975.
Atomic research:
Niels Bohr to the top of New Mexico, USA, for security reasons, when a new project, working in a secret laboratory at Los Alamos known is the name of Nicholas Baker. Plays an important role in this project, a consultant or a project coming up 'occurs. On nuclear arms race and said: "I'm going to America. They will help develop the atomic bomb. Requirements"
Bohr's atomic secrets to the international scientific community believed to have been shared. Bohr, Robert Oppenheimer, and after the meeting, bought President Franklin D. Roosevelt that he wore Manhattan Project, in cooperation with Russia, they hope to explain the results of the proposed improvements. UK, United Kingdom, Roosevelt tried to get back to Bohr's proposal was approved. Winston Churchill opposed the opening of Russia in his letter that: "In any case, it is my Boru, close to the edge of man's sin must have written references should be limited."
After the war, Bohr in Copenhagen, the peaceful use of nuclear energy back on the recommendations. Denmark, the elephant, the logo on the front, two large taijitu characters (design) and the Latin motto sunt quite the opposite: It has been awarded an order for additional contrast. He died in Copenhagen in 1962 from the heart. This was an underground Assistant Kirkegård Nørrebro in Copenhagen.
Contributions to physics:
- The Bohr model of the atom, the theory that electrons travel in discrete orbits around the atom's nucleus.
- The shell model of the atom, where the chemical properties of an element are determined by the electrons in the outermost orbit.
- The correspondence principle, the basic tool of Old quantum theory.
- The liquid drop model of the atomic nucleus.
- Identified the isotope of uranium that was responsible for slow-neutron fission - 235U.
- Much work on the Copenhagen interpretation of quantum mechanics.
- The principle of complementarity: that items could be separately analyzed as having several contradictory properties.
