Main Page | See live article | Alphabetical index John Stewart Bell (June 28 1928 - October 1 1990) was an Irish physicist. Bell was born in Belfast, Northern Ireland. In 1964 he demonstrated that quantum mechanics is nonlocal and in some ways appears to require supraluminal signaling. He showed that von Neumann’s proof against deterministic quantum mechanics lacked rigor and that Bohm’s work got around von Neumann’s objections through the use of supraluminal signaling. He later defended his work against those distorting its meaning to favor indeterministic quantum theories. He became a supporter of Bohm’s work and called its suppression a "scandal" within physics. He died in Belfast. See also: Bell's theorem EPR paradox CHSH inequality GHZ experiment Quantum entanglement This article is a stub. You can help Wikipedia by fixing it.
