PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.As far as I can see, the things being discussed are independent of any interpretation; they're experimental facts and how the... -
PeterDonis replied to the thread I Gauss' law seems to imply instantaneous electric field.Is not applicable the way you are using it in scenarios where there is time variation in the fields. If you dig into the details of how...
