All I read is that the problem is about the synchronization or simultaneity convention. But this is only an issue if the measurements...

What would be wrong with my proposal, i.e. measure wavelength and frequency of a leaving and the reflected beam separately?

Hi. According to Wikipedia: The "one-way" speed of light, from a source to a detector, cannot be measured independently of a convention...

If ##A_i## and ##B_i## were QM operators and we were calculating QM expectation values would then the equation ##\langle A_1 B_1+A_1...

Let's assume two silver atoms get spin-entangled and sent through two Stern-Gerlach apparatuses. I guess atoms are heavy enough for an...

I don't know what I was thinking when I asked the first question (it's right there in Ampère's law). And what about...

Hi. Does displacement current create a magnetic field by Biot-Savart? I googled and found contradictory answers. Also, in the presence...

Hi. To close the locality loophole in Bell tests, detector settings may be changed randomly "just before the photon arrives". Or I have...

Trying to find that article, I came across this lecture for the general audience...

Hi. I vaguely remember an article in a popular science magazine that tried to illustrate the problem of the reconcilability of QM and...

The article I read first showed ##A_1 B_1+A_1 B_2+A_2 B_1-A_2 B_2=A_1 (B_1+B_2)+A_2 (B_1-B_2)=\pm 2## from which follows that ##\langle...

So as I understand it, the fact that the expectation value of a sum is the same as the sum of the expectation values is crucial in the...

https://onlinelibrary.wiley.com/doi/abs/10.1002/piuz.201501412 But it's behind a paywall. But isn't ##A_1 B_1+A_1 B_2+A_2 B_1-A_2...

It's "Physik unserer Zeit", 6/2015 (46), "Endspiel für den lokalen Realismus".

I can, but it's in German.
