Niels Bohr went from goalkeeper and self-taught glassblower to the physicist who reimagined the atom and won the 1922 Nobel Prize. This deep dive traces his prize-winning surface tension experiment, his work with Ernest Rutherford, and his use of Max Planck’s quantum ideas to explain why atoms do not collapse, with electrons jumping between fixed orbits.

We also cover his Copenhagen institute, the prediction that led to the discovery of hafnium, the principle of complementarity, his disputed 1941 meeting with Werner Heisenberg, his escape from occupied Denmark, his role in the Manhattan Project, and his later call for an open world of scientific cooperation.
