It's the second time I've posted this message, and my english simply sux, so excuse me if I will not be able to explain my misunderstanding quite clear.
Let's imagine a verry long metal cable, which is heated at one head. The quasi-free electrons at that head, as their energy increases, must change their quantum state, but there must be a way for them to *know* what the other electrons quantum states are, in order not to occupy the same state.
So how does a fermion *know* what states are not possible to ocupy?
