John S. Bell (Belfast, 28 de junho de 1928 — Belfast, 1 de outubro de 1990) foi um físico, conhecido pelo teorema de Bell, apontado por alguns na comunidade da física quântica como uns dos teoremas mais importantes do século XX. [1] Nasceu em Belfast, Irlanda do Norte, e graduou-se em física experimental pela Queen's ...

Bell was born in Belfast, Northern Ireland. When he was 11 years old, he decided to be a scientist, and at 16 graduated from Belfast Technical High School. Bell then attended the Queen's University of Belfast, where, in 1948, he obtained a bachelor's degree in experimental physics and, a year later, a bachelor's degree in mathematical physics. He w...
In 1964, after a year's leave from CERN that he spent at Stanford University, the University of Wisconsin–Madison and Brandeis University, Bell wrote a paper entitled "On the Einstein–Podolsky–Rosen paradox". In this work, he showed that carrying forward EPR's analysis permits one to derive the famous Bell's theorem.The resultant inequality, derive...
Bell's interest in hidden variables was motivated by the existence in the formalism of quantum mechanics of a "movable boundary" between the quantum system and the classical apparatus: Bell was impressed that in the formulation of David Bohm's nonlocal hidden-variable theory, no such boundary is needed, and it was this which sparked his interest in...
In 1972 an experiment was conducted that, when extrapolated to ideal detector efficiencies, showed a violation of Bell's inequality. It was the first of many such experiments. Bell himself concluded from these experiments that "It now seems that the non-locality is deeply rooted in quantum mechanics itself and will persist in any completion.": 132 ...
Bell and his wife, Mary Ross Bell, also a physicist, contributed substantially to the physics of particle accelerators, and with numerous young theorists at CERN, Bell developed particle physics itself. An overview of this work is available in the volume of collected works edited by Mary Bell, Kurt Gottfried, and Martinus Veltman.Apart from his par...
Bell died unexpectedly of a cerebral hemorrhage in Geneva in 1990. Unknown to Bell, he had reportedly been nominated for a Nobel Prize that year.: 3 : 155 : 374 His contribution to the issues raised by EPR was significant. Some regard him as having demonstrated the failure of local realism (local hidden variables). Bell's own interpretation is that...
