The Birth of the Nuclear Age

JAN 01, 1993
When Ernest Rutherford dismissed nuclear energy as ‘moonshine’ in 1933, Leo Szilard took it as a personal challenge. Nine years later, under a Chicago grandstand, Enrico Fermi demonstrated the first self‐sustaining uranium pile.
Albert Wattenberg

Fifty years ago last month Enrico Fermi demonstrated that a self‐sustaining nuclear chain reaction could be produced and controlled. It was a quantitative experiment, and it was Fermi who decided upon all the cautious steps to be followed and all the measurements to be made.
