Ask most people when the nuclear age began and they will probably answer Hiroshima, Aug. 6, 1945. It did not. Three weeks earlier, on July 16, the world’s leading scientists, including Lawrence, Fermi, Teller, and, of course, Oppenheimer, assembled in the middle of the night at an abandoned ranch near Alamogordo.
