Thanks! They both concern only the particle. The vector potential ##\mathbf{A}## and scalar potential ##\phi## correspond to an external electromagnetic field (they do not take into account the field created by the charged particle).

Could you please give the full citation of that article?

Yes. To quote from Sakura and Napolitano, Modern Quantum Mechanics:

Correct. You still have ##\mathbf{p} = -i\hbar \nabla##, but ##\mathbf{p}## is no longer ##m \mathbf{v}##.

There is so much wrong there. First, even by the logic of the post, if they were a on three-hour tour, the farthest they could have gone during the tour was 20.7 miles. Second, they were caught in a storm, so the cruising speed is irrelevant. Third, it is said nowhere in the theme song that...

I don't want to derail the thread, but Shakespeare wrote that about 2 centuries earlier:
