Like.
Well, his books have sold out well. Ultimately a matter of taste. -
bhobba reacted to PeterDonis's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
"Only one" in what sense? It's an antisymmetric tensor field with six independent components, as @Matterwave said in post #251. Also...

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

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...

"The counting" that I was referring to was the one in Art Hobson's quote mentioned in post #241 which I assumed was meant for fields in...

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...

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...

The fields could be the fundamental entities. They wouldn't be made of anything else. Why is it a problem to have many fields in the...

Some really interesting reads in this thread.. I think that a Big 5 personality test together with an IQ test would show a more...
