I downvoted for basically the same reason as 'danbruc -- the comment contains inaccuracies (as far as I understand physics, IANAP) that don't become accurate just by appending "Right?" to them. I don't really read that "Right?" as condescension like 'humbledrone but more as a verbal tick. I hear it from others and even suffer from it myself sometimes, the idea is that a "Right?" pause offers the other party in the conversation a chance to interrupt and correct you, because you're not entirely certain of your own assertions. But that doesn't work so well in written communication except maybe with instant messaging.

I gave you an upvote for persisting in getting corrections/tips from people like 'danbruc and 'lutusp though. Since you were interested in simulation you might enjoy this article (or others on his site) from an actual physicist: http://oyhus.no/QuantumMechanicsForProgrammers.html
