Undecidability and indeterminism by Klaas Landsman
By KLAAS LANDSMAN
Essay Abstract

The famous theorem of Bell (1964) left two loopholes for determinism underneath quantum mechanics, viz. non-local deterministic hidden variable theories (like Bohmian mechanics) or theories denying free choice of...
