It seems to me that your concern has changed drastically. If I read your post right, now you are saying the authors performed their math...

I would be careful with the word "real" here and also careful how you use your symbols. As 3-vectors, ##\vec{E}## and ##\vec{B}## are...

Thanks. I'll look into those... The size of my Zotero physics collection has grown considerably since I joined PF!

Which means this... ...is exactly what we should expect since we have changed the observables. So I don't understand why you think this...

You might have a legitimate concern. But from my reading, I can't tell. What I have read of the paper seems fine to me.

I guess I don't understand your concern because to me, the whole point of changing detector settings is to change the (quantum)...

I'm interested in learning enough to understand relativity (and QFT). I studied physics in college (decades ago), so I guess I'm at a...

It does if the state in between is not an eigenstate of the Hamiltonian. Then the state will change by time evolution in between the...

A more complete exposition of the situation might require a really long post. Perhaps you could elucidate further your core question or...

Do you want more of a solid mathematical foundation in differential geometry? Or just what's needed to do relativity? Or something in...

Remember to use the metric to keep the indices in the right place. In GR this can bite. In SR this leads to some negative signs in the...

I have not read through the entire paper and just glanced around the relevant sections so take this with a grain of salt. My...

Basically, but with the important caveat that there are no magnetic monopoles. See the rest of the quoted message.

I vote for "lights"... ##\frac{light\cdot \cancel{second}}{\cancel{second}}=light##

If you open the video description it disclaimers that this is AI generated Feynman.
