Me too. I had it, sold it, and bought it again recently, so that I can solve problems from it (I didn't do it the first time). -

Ah, ok. Yes, I would not trust the Wikipedia page's description of the actual details of the hypothesis.

This question isn't a question of physics, because "truly identical" is vague ordinary language. If I have one electron with spin up in...

No. I don't think the hypothesis was intended as a serious scientific theoretical hypothesis; it was a typical whimsical suggestion of...

That's true, but that hypothesis is not the same as Wheeler's "one electron" hypothesis. In quantum field theory--or more precisely...
