Niels Bohr investigated the structure of the atom and won the Nobel Prize in Physics in 1922 for discovering the Bohr model. He developed the liquid drop model of the atomic nucleus, proposed the idea of complementarity and identified the U-235 isotope essential for nuclear fission. After fleeing the German invasion of Denmark, he worked on the development of the atomic bomb at Los Alamos in the United States.Know More
The Bohr model proposes electrons orbit the nucleus because of electromagnetic forces rather than gravity. Because of this difference, electrons do not collapse into the nucleus but travel from one orbital shell to another as energy levels change.
As a Danish citizen, Bohr resisted involvement with German nuclear power research and aided many Jewish scientists in their escape from Nazi power. He fled Denmark in 1943 and eventually made his way to London, where he was involved with experiments for a viable nuclear fission bomb.
Bohr was adamant that atomic research should be shared, causing Winston Churchill to view him as a security risk. He organized the Atoms for Peace Conference in Geneva in 1955.
Bohr's son Aage Niels Bohr also contributed to the world of physics. Aage won the Nobel Prize in Physics in 1975.Learn more about Inventions
Alfred Nobel is the founder of the Nobel Prize, which honors men and women throughout the world for achievements in medicine, chemistry, physics, literature and works of peace. Nobel was a wealthy man who left most of his fortune to establish the Nobel Prize. The Nobel Prize was founded via Alfred Nobel's last will and testament in 1895, and the first award was granted in 1901.Full Answer >
The Danish physicist Niels Bohr developed a model of the atom that combined Ernest Rutherford's discovery of the nucleus with the quantum ideas proposed by Max Planck. This solved the problem of why the electrons did not immediately collapse into the nucleus. Bohr received the Nobel Prize in Physics for his discovery in 1922.Full Answer >
Albert Einstein made numerous accomplishments that advanced humanity's thinking about physics, including the Special Theory of Relativity and the General Theory of Relativity, according to the official website of the Nobel Prize. Einstein earned the Nobel Prize for Physics in 1921. The scientist also won the Copley Medal in 1925 and the Franklin Medal in 1935.Full Answer >
Niels Bohr, the 20th-century Nobel laureate Danish physicist, discovered and developed a realistic model of the atom, known as the Bohr model. Additionally, he developed the principle in quantum mechanics known as complementarity.Full Answer >
