Bruno does. Nobody is arguing it. Bruno argues it. Honestly it's hard to understand why you have such an agitated bee in your > bonnet about superpositions. I don't like misleading ideas.

Once again, you're simply arguing at cross purposes with Bruno, > who clearly understands QM perfectly well. Not in my opinion. He thinks that an Up or Dn measurement is the same as measuring Up + Dn or Up - Dn because the wf can be written that way in some basis. He's not saying the photon can be measured as up and down at the same time. > He's just saying that any superposition of up and down is an eigenvector in > some other orientation of the apparatus. It's not. My last post proved this with utmost clarity. Up + Dn or Up - Dn is never an eigenfunction regardless of the orientation of the apparatus. How could it be if measuring Up and Dn separately exhausts the total probability of unity? I think you need to rethink this issue. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
