Bohr was already an accomplished scientist when the young German Heisenberg joined his group, and Bohr began mentoring him. Heisenberg became one of the leading figures in formulating the new quantum mechanics. Later, Heisenberg joined the group of German physicists developing nuclear weapons for Nazi Germany. Why did Heisenberg return to Copenhagen in 1941? Denmark was at that time already occupied by Germany. [...]
