This whole discussion has been very enlightening to me. It's news
to me that von Neumann was wrong. I must confess that I, like most
people, have always accepted his assertion about hidden variables
without looking at the proof. Not only that -- I still haven't read the
proof. Now I'm taking your word for it that he was wrong!! ;-)
Going beyond group-think is almost impossible. But we have to keep
trying.
BTW, "Grete Hermann" sounds like a female name. If so, let's give
credit where credit is due.
