In , he assigned the chain-reaction patent, to the British Admiralty to ensure its secrecy. He later wrote that the concept of a nuclear chain reaction "suddenly occurred to me" in Sept.

He drafted a letter and circulated it to the various Manhattan Project locations. This letter outlined the possibility of achieving a nuclear chain reaction and its implications for the development of nuclear weapons for national defense. After earning his Ph. The paper is also the first equation of negative entropy and information. Hughes, J. It was a very poor and inefficient way of producing energy, and anyone who looked for a source of power in the transformation of the atoms was talking moonshine.

Shaken by the destructive force of the weapon he had helped to create, Szilard decided to dedicate the rest of his life to nuclear safety, arms control, and the prevention of further development of nuclear energy for military purposes.

The experiment they were completing had taken months of preparation. Szilard gave up his work in nuclear physics and joined the Chicago faculty as a professor of biophysics. Szilard died in his sleep of a heart attack on May 30, They invented the chemostata device for regulating the growth rate of the microorganisms in a bioreactor[72] [73] and developed methods for measuring the growth rate of bacteria.

WeisskopfJames Watson and John Kendrew. Szilard rebelled. Taking a conservative view that every possible neutron must be preserved, the majority opinion initially favored cooling with helium, which would absorb very few neutrons. He wired Frederick Lindemann at Oxford and asked him to send a beryllium cylinder.
