John Stewart Bell, II
(28 Jun 1928 - 1 Oct 1990)

Northern Irish physicist who has been described as breathing “new and exciting life into the foundations of quantum theory.” In 1964, he mathematically proved that certain quantum correlations, unlike all other correlations in the Universe, cannot arise from any local cause.


Science Quotes by John Stewart Bell, II (3 quotes)

Apparently separate parts of the world would be deeply and conspiratorially entangled, and our apparent free will would be entangled with them.
— John Stewart Bell, II

I am a quantum engineer, but on Sundays I have principles.
— John Stewart Bell, II
As quoted by Nicolas Gisin in 'Sundays in a Quantum Engineer’s Life', collected in Reinhold A. Bertlmann, A. Zeilinger (eds.),Quantum (Un)speakables: From Bell to Quantum Information (2002), 199. Gisin, one of his PhD students, recollects this statement as the opening remark at an impromptu evening talk in a basement room during the annual meeting of the Association Vaudoise des Chercheurs en Physiques, Montana (Mar 1983).

Long may Louis de Broglie continue to inspire those who suspect that what is proved by impossibility proofs is lack of imagination.

Quotes by others about John Stewart Bell, II (1)

A distinguished Princeton physicist on the occasion of my asking how he thought Einstein would have reacted to Bell’s theorem. He said that Einstein would have gone home and thought about it hard for several weeks … He was sure that Einstein would have been very bothered by Bell’s theorem. Then he added: “Anybody who’s not bothered by Bell’s theorem has to have rocks in his head.”
In 'Is the Moon There When Nobody Looks? Reality and the Quantum Theory', Physics Today (Apr 1985), 38-47.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
