Haldane did not foresee the computer, the most potent agent of social change during the last fifty years. He expected his Daedalus, destroyer of gods and of men, to be a biologist. Instead, the Daedalus of this century turned out to be John von Neumann, the mathematician who consciously pushed mankind into the era of…
I have a friend, a young American physicist, who spent a year doing theoretical physics in the Soviet Union. He likes to go to the Soviet Union, not because it is a good place to do physics, but because it is a good place to observe the human comedy. When he went back to Leningrad recently for a shorter visit, he…
I remember a talk that Von Neumann gave at Princeton around 1950, describing the glorious future which he then saw for his computers.

Where the system’s software is stored. Input device(s). Input slave processors and relative electrical components. Output device(s). Output…
If we somehow manage to make an atomic size computer, it would mean that the dimension, the linear dimension, is a thousand to ten thousand times smaller than those very tiny chips that we have now. It means that the volume of the computer is 100 billionth or 10^-11 of the present volume, because the volume of the…
