Résumé : Bell’s theorem highlights the peculiarities of quantum mechanics in a strikingly clear way. The theorem proves the incompatibility of 3 things, namely determinism, locality and the exactness of quantum mechanics: at least 1 of the 3 has to be wrong. In the meanwhile experiments have convincingly shown that quantum mechanics is correct – implying, it would seem, that one has to give up either the principle of determinism or locality (or both) ! But what exactly are Bell’s determinism and locality ? And: are there hidden assumptions in Bell’s proof ?
Note that Bell’s theorem is maybe the only theorem that would bring a philosophical idea, the millennia old principle of determinism, “in the laboratory” (it has therefore sparked the term “experimental metaphysics”). I will try to highlight both a few philosophical and mathematical unresolved problems.
