2022 Physics Nobel –


I am pleased that this year’s Nobel in Physics honored work that had its foundation in J. S. Bell’s work, and it is unfortunate that because of his untimely death he cannot receive the Nobel.

However there is a technical inaccuracy in the announcement:

John Clauser developed John Bell’s ideas, leading to a practical experiment. When he took the measurements, they supported quantum mechanics by clearly violating a Bell inequality. This means that quantum mechanics cannot be replaced by a theory that uses hidden variables.’

Actually it only rules out locality. Bohmian mechanics is non-local, and it was, somewhat ironically, Bell’s preferred interpretation of quantum mechanics.
