This is a comment I prepared for Prof. Penrose. Any comments?

I think your comment is excellent, and I hope Prof. Penrose will have time to take a look at it and answer you...Except for one thing: could you give me an example of a potential which is velocity-dependent?

The electromagnetic vector potential is velocity-dependent. This gets subtracted out in the Hamiltonian, but then the minimum isn't at p_i = 0.
