comment Historical background of wave function collapse
Yes, I did miss that point. I read the Mott paper a couple of years ago and I don't remember the role of ionization in the process. I don't believe Mott dealt in any way with the mechanism of track formation. What exactly is the importance of ionization? Isn't the cloud chamber in a metastable state to begin with, and won't the clouds eventually just form on their own without any disturbance?

Thank you for the excellent response, Ron. The comment field is too short for me to respond to it so I have placed my response as an edit to my question.

comment How is this classical “paradox” resolved in electromagnetism?
I'm going to eat my words. Having posted the picture, it's pretty obvious that the guy pushing the pipe is doing the work. There is a reaction force from the magnetic field that he is pushing against, and that's why the electrons move to the left, but obviously the magnet isn't providing any energy.

Ron, I'm going to edit my response with a picture in response to your comment. The constraint force is indeed important, but I think you will agree it turns out to be the vxB force which does the work after all...

comment How can indeterminacy in quantum mechanics be derived from lack of ability to observe a cause?
Contrary to Nick's implication, I think the question is perfectly worded and it is in fact THE question of quantum mechanics. The uncertainty is frequently described in terms of a mere practical issue; even Feynmann does this in explaining the double slit. EPR insists the uncertainty goes much deeper than this, and Bell makes it a practical issue subject to experiment. If the OP doesn't understand this, he's in good company.

comment Measuring the spin of a single electron
I stumbled independently on Jared Stenson's master's thesis, and it has some things even more interesting that the paper you've flagged. The Master's Thesis is at contentdm.lib.byu.edu/ETD/image/etd908.pdf and I discuss its implications in my blog, which I've linked to in my own answer.

For a mathematical demonstration that you cannot distinguish a collection of pure eigenstates from a system in mixed superpositions, see this earlier stackexchange discussion: physics.stackexchange.com/questions/8123/…

comment Is energy conserved in decay of hydrogen atom in superposed state?
The spectrum is discrete because the energy level transitions are only driven by exact frequencies. But that has nothing to do with the theory that once a transition is started it has to go all the way. I elaborate on these topics in my blog: this article marty-green.blogspot.com/2011/10/… shows how atoms behave like tiny classical antennas, and this article marty-green.blogspot.com/2011/12/… refrences a very good discussion on this site regarding alternative paradigms.

comment Is energy conserved in decay of hydrogen atom in superposed state?
The spectrum is exactly the same in either paradigm. The discretenesss of the spectrum has nothing to do with the supposed discreteness in the emission/absorption processes.

comment Testing my understanding of QM - The Double Slit Experiment without the slit
@harry I hope you will read the article which I linked to above. In it I show how the statistics of detection are the same if you model photons or continuous waves. It seems in quantum mechanics you are really not allowed to say that just because a particle was detected here, it must have been emitted from there at such-and-such a time. It's one of those delicate balancing acts between what we're allowed to know and what we're not. A pea-shooter would hugely upset that balance.
