100 years anniversary for Niels Bohr's Atomic Model

Niels Bohr’s model of the atom revolutionized physics when it was published in 1913. The model was the first consistent description of how electrons contributed to constitute matter.

The ingenious idea Niels Bohr used in his model was to quantize the atom – a brave idea as the world was considered classical and not quantized. As a result Niels Bohr’s model of the atom was not generally accepted at first. But eventually leading physicists of the time became convinced of its value. Mainly because it solved two mysteries, namely: why atoms radiated certain colours of light when heated and why the atom consisting of a positive as well as a negative electrical charge did not self-destruct. In this video physicist Troels C. Petersen from the Niels Bohr Institute and director of the Niels Bohr Archive Finn Aaserud celebrate the 100 years of the atomic model.
