A quiet, shy boy, Enrico Fermi found escape in books on mathematics and physics. To him, those subjects made sense. The outside world was far more confusing. It was a place where Fermi"s older brother died during a simple operation, where his young wife was persecuted for her religion. It was also a world Fermi would radically change. The experiments he conducted as a refugee in the United States would soon lead to an energy of unimaginable power and potential danger. This is his story.
