Bohr wins gold medal
Bohr wins gold medal at competition study surface tension of water, sponsored by the Royal Danish Association of Sciences and Letters to investigate the concept proposed by Lord Rayleigh. Bohr used his father’s lab in the university. He made his own glassware for the competition and won by working with finite rather than infinitesimal amplitudes. -
Bohr earns his master’s degree
Bohr earned his master’s degree on the electron theory of metals. The topic was assigned by his supervisor, Christian Christiansen. He begins working to elaborate his master’s thesis into his much larger doctor’s thesis. He studied the models proposed by Paul Drude and Hendrik Lorentz where electrons behaved like a gas. -
The Trilogy
Bohr released three papers (“the trilogy”) on the Bohr model for atoms. His work adapted Rutherford’s nuclear structure to Plank’s quantum theory. He worked on the theory of electrons traveling in orbits around the nucleus. Work in 1921 paper showed the properties of elements are determined by the number of electrons in the outer orbits.

Nobel Prize
Bohr wins a nobel prize for his work and investigation into the structure of atoms and radiation emitted from them. The award recognized the Trilogy and his early work leading to his research. BOHR, N. Atomic Structure. Nature 107, 104–107 (1921). https://doi.org/10.1038/107104a0 -
