Electron spin

@metal-brain said
No, you refused to answer and you referred me to wikipedia because you are incapable of answering those questions without contradicting yourself. You said electron spin could be measured and later you said there was no speed to measure.

You clearly do not know what you are talking about.

I already explained on the first page there is no such thing as "electron spin speed."

I also told him this. And I didn't get that from wiki (don't get why he is so stupidly angry about us getting quotes from wiki especially as HE also sometimes quotes wiki). And he keeps shouting to us we don't answer his questions or explain anything to him after we just did!

Do electrons spin faster than the speed of light?

Light doesn't spin

Photons are spin 1. So light does spin in this sense.

yes, but they don't spin like a spinning top.

What is your source of information?

So there is nothing to measure? You are still contradicting yourself.

He is a physicist.
Do you deny that a photon is defined as having a spin of either -1 or 1?

This thread is about electron spin, not photons.
He has failed so he is digressing into a different subject. That is what people do when they have lost the debate. He knows he contradicted himself and he cannot undo his mistake.

Kazet screwed up and you are defending his screw up and making yourself look like a screw up as well. You have very poor judgement.

If you think its so wrong to steer the conversation of this thread so to also include that of spin of photons then why did you clearly deliberately steer the conversation to include that of photon spin by asking "What is your source of information?" about the spin of photons being 1? Hypocrite!

If you can prove photons spin I will talk about it, but nobody has proven that on here.

Arr, at least, you have just admitted you think there may be no proof. Just as I suspected.
It took my about 30 seconds of my time to google search and find this about that experimental proof;

This just shows your delusional arrogant complete ignorance on the subject.

There is something to measure, just not the "speed" of intrinsic spin, which is not a thing. Spin can be measured e.g. through the Stern-Gerlach experiment.

That was from memory, but a reference for this is easy to provide. This is the Particle Data Group's listing for Gauge and Higgs Bosons, the relevant quantity is listed as J.

If it isn't speed being measured what is being measured?
