Bohr-Van Leeuwen Theorem
This theory developed by Niels Bohr states that when you apply statistical mechanics and classical mechanics equally and consistently, the magnetization of the thermal average will always be zero. It states that "in a uniform magnetic field and in thermal equilibrium, the magnetization of an electron gas in the classical Drude–Lorentz model vanishes identically." (Savoie 2015). -
The Bohr model
Niels Bohr and his colleague, Ernest Rutherford, present the "Bohr Model" of an atom, otherwise known as the "Rutherford-Bohr Model". In the Bohr model of the atom, electrons travel in a circular path around the nucleus. They can also move from one orbit to another by either absorbing energy, or sending out energy. Bohr Model -
Nobel Prize in Physics
Niels Bohr was awarded the Nobel Prize in Physics for his work in atomic theory. The Bohr model which showed that Electrons do not clash with the nucleus as previously thought. This discovery was also seen as the start to quantum theory. Short Clip of Niels Bohr Just Before Receiving Nobel Prize -
The Theory of Spectra and Atomic Constitution
Niels Bohr published his book "The Theory of Spectra and Atomic Constitution". This work contains three essays by Niels Bohr on the application of quantum theory to atomic structure Bohr, N. (1922) The Theory of Spectra and the Atomic Constitution. Cambridge University Press, Cambridge. -
Liquid Drop Theory
The only time I could find for this theory was the "Late 30's" so I just placed it in the middle of the late 1930's. Bohr stated that the nucleus of an atom is represented very accurately by a liquid drop. This theory would then go on to be crucial in the splitting of uranium atoms and the development of the atomic bomb. -
Atomic Physics and Human Knowledge
Published in 1957, after Niels Bohr's "The Theory of Spectra and Atomic Constitution" comes the sequel "Atomic Physics and Human Knowledge". A series of articles written from 1932 - 1957, further going on about his studies and findings in atomic structure and quantum mechanics. Bohr, Niels. Atomic Physics and Human Knowledge. Wiley, 1958.
