For a time, Wheeler regarded nuclear physics as the best way to “do battle with nature.” But then he became attracted to the simplicity of the muon, which is immune to the strong nuclear force. He himself, however, could not escape the ramifications of that force in a world at war.

On a morning walk across the snowy Princeton campus early in 1939, Niels Bohr suddenly understood that the rare isotope uranium-235 was alone responsible for the recently discovered nuclear fission.
