Proper time recorded by some particular observer's clock at some particular event is independent of any choice of reference frame. But...

It's the angle, which changes along the wave, between the ##x## - ##y## basis and the principal axis of polarization of the wave. I'm...

"Only one" in what sense? It's an antisymmetric tensor field with six independent components, as @Matterwave said in post #251. Also...

I don't think so. I think your mistake was trying to give ##\alpha## the wrong physical meaning. As I noted in post #11, ##\alpha## is...

No, charge distributions and EM waves are already described within Maxwell's theory of the electromagnetic field and its sources. I...

I'm not sure what this question even means. In actual experiments, there is no such thing as "quantum interference pattern" vs...

But this is a special case, and you can't base a general count of "number of fields" on special cases. The ##B## field doesn't cease to...

No, it doesn't. The fact that the field is generated by the sources does not mean it incorporates the sources. The field and the sources...

Yes, it is not trivial. :wink: As in, yes, we have no bananas: https://en.wikipedia.org/wiki/Yes!_We_Have_No_Bananas

Yes, it is. Hobson did say "at least" 25 fields.

Up, down, strange, charm, top, bottom. Yes, that counting leaves out the quarks' color charge. But note that, for example, when we say...

Yes, I see that from the paper, thanks for the reference. Key things to keep in mind: the coordinates ##U## and ##V## are null. The...

6 leptons, 6 quarks, 12 gauge bosons, and the Higgs in the Standard Model. Of course this counting leaves out a lot of things. Hobson...

Do you mean this metric? If not, can you give a reference?

Not in the case where photons escape to infinity. In such a case, this... ...or its quantum analogus, is simply wrong. Photon that...
