"He (American biologist William A. Arnold) could have gone to Berkeley to pick up radioisotope technique, but would have missed living in Copenhagen, learning from de Hevesy - would have missed contributing a coinage to the gamble that is history.... 'Later that day Frisch looked me up and said, 'You work in a microbiology lab. What do you call the process in which one bacterium divides into two?' And I answered, 'binary fission'. He wanted to know if you could call if 'fission' alone, and I said you could'"
-- From "The Making of the Atomic Bomb" by Richard Rhodes, Frisch referring to Otto Frisch, who with Lise Meitner first postulated nuclear fission.
