Why was Niels Bohr Important?:
He was part of the group of scientists that invented the atomic bomb as part of the Manhattan Project. He worked on the Manhattan Project under the assumed name of Nicholas Baker for security reasons.
Niels Bohr - Model of Atomic Structure:
- that electrons traveled in orbits around the atom's nucleus
- that the chemical properties of the element was largely determined by the number of electrons in the outer orbits
- that an electron could drop from a higher-energy orbit to a lower one, emitting a photon (light quantum) of discrete energy
Werner Heisenberg and Niels Bohr:
Niels Bohr Biography 1885 - 1962:
Niels Bohr EducationIn 1903, he entered Copenhagen University to study physics. He received his Master's degree in Physics in 1909 and his Doctor's degree in 1911. While still a student he was awarded a gold medal from the Danish Academy of Sciences and Letters, for his "experimental and theoretical investigation of the surface tension by means of oscillating fluid jets."
Professional Work & AwardsAs a post-doctoral student, Niels Bohr worked under J. J. Thomson at Trinity College, Cambridge and studied under Ernest Rutherford at the University of Manchester, England. Inspired by Rutherford's theories of atomic structure, Bohr published his revolutionary model of atomic structure in 1913.
In 1916, Niels Bohr became a professor of physics at the University of Copenhagen. In 1920, he was named director of the Institute of Theoretical Physics at the University. In 1922, he was awarded the Nobel Prize in Physics for recognition of his work on the structure of atoms and quantum mechanics. In 1926, Bohr became a Fellow of the Royal Society of London and received the Royal Society Copley Medal in 1938.
The Manhattan ProjectDuring World War II, Niels Bohr fled Copenhagen to escape Nazis prosecution under Hitler. He traveled to Los Alamos, New Mexico to work as a consultant for the Manhattan Project.
After the war, he returned to Denmark. He became an advocate for the peaceful use of nuclear power.
