@metal-brain saidIt's angular momentum, not speed.
What was the speed?

You make assumptions with that question. Like you would have to know the size of the thing and a way to measure it. What if an electron is actually a point size particle, somewhere around plank constant size. Then you would have to know how many RPS it was flying and THEN you could calculate 'speed'.
But it would be velocity anyway, not just speed which is more like a car speeding down the road in a straight line.
@kazetnagorra saidYou said electron spin speed could be measured and now you are claiming there is no speed to measure. You have contradicted yourself.
It's angular momentum, not speed.

@metal-brain saidThat's what ALL us science experts have been telling you all the long.
You said electron spin speed could be measured and now you are claiming there is no speed to measure.
You have contradicted yourself.No, it isn't a contradiction. And this quote shows you are confused.
@kazetnagorra saidYou said it can be measured. Now you are saying it can't.
Intrinsic electron spin can be measured in numerous ways, the classic example is the Stern-Gerlach experiment.

Maybe you should have looked that up before commenting on it?
You are contradicting yourself.
@metal-brain saidI said spin could be measured. I posted this link on the first page of this thread. Perhaps you ought to consider reading it?

@metal-brain saidHe never said electron spin can't be measured.
You said it can be measured. Now you are saying it can't.
You are contradicting yourself.
He clearly didn't contradict himself.
What is wrong with you?
@sonhouse saidMaybe you would.
@Metal-Brain
So maybe you will learn something if you deign to actually read his post.
@metal-brain saidWhat about it?
He said this:
"It's angular momentum, not speed."
How does that say/imply electron spin can't be measured?

@metal-brain saidWrong.
He is saying there is no speed. No speed, nothing to measure.
There is spin without rotational speed to measure.
@metal-brain saidThe spin is associated with a magnetic moment. In the Stern-Gerlach set up it's the magnetic moment that is measured.

@deepthought saidWhat exactly is being measured and why is it called "spin"?
