There's something I don't quite get about most illustrations about Bell's inequality theorem. I will explain what:(adsbygoogle = window.adsbygoogle || []).push({});

Consider a pair of entangled photons fired at two arbitrarily oriented polarizers. I most explications, it seems the author suggests that the hidden variable represents the binary value (yes/no) that determines if the photon is, or is not, going to pass the filter,independent of the oriëntation of the filter.

This seems a little silly to me however. If that would be the case, either the photon already 'knew' the position of the filter, or the filterhas no influence whatsoever!It would make more sense to me if the hidden variable was aprescriptionof 'how to act' if it would encounter the filter in a certain spacial oriëntiation. Then the filterin conjunction with the hidden variablewould determine if the photon would pass or not!

The proof would still hold because the decision to pass or not would still be local.

So, what is the correct interpretation of Bell's theorem?
