A good idea. And then when you're done we should turn it into a wikibook like I did with mine, so as to reach a wider audience --- I'll help if you like.

I would plan to begin around May this year. I know it is pretty early to be proposing this, but I plan to treat it like a proper course, similar enough to those I actually lecture, so I would need some time to prepare.

You don't have to prepare the whole thing before you start, do you? I didn't.

Re: A peanut gallery, perhaps?
I don't think a separate peanut gallery is a good idea. If someone has a question, then the answer should be in-thread for the general edification of the readers.

In my own thread I also broke forum etiquette (as I announced I would at the start) by going back and changing posts in response to comments.

Re: Basic Plan.
I think there should be a section on how quantum mechanics means that Deepak Chopra is right about everything.

Re: Basic Plan.
Even the name is unfortunate, reflecting its historical origin. [...] Since, unfortunately, in classical mechanics the second charge only comes from rotations, this leads to the mental picture of an electron rotating, however this is false.

So ... let's see if I've got this right. The reason for the name is that if the world was classical instead of quantum, then the Stern-Gerlach experiment would have been measuring how the particles spin. The results of this particular experiment were consistent with them actually, classically spinning, but only at a given rate. So people exclaimed "Ah, spin is quantized!" But really they weren't spinning at all, as has been shown by other experiments (which you allude to and I know nothing about.) It's just that their magnetic properties, not actually caused by them spinning, gave results consistent with the hypothesis that (a) they were spinning (b) the spin was quantized.
