That all changed on Feb. 11, 1939, with a letter to the editor of Nature – a premier international scientific journal – that described exactly how such a thing could occur and even named it fission.

Werner Heisenberg, one of the greatest physicists of the 20th century, played a central role in Germany’s atomic bomb program during WWII. But a scientific mistake he made effectively derailed Germany ...
