We're all born with curiosity, but at some point, school usually manages to knock that out of us. ...[M]y main responsibility as a teacher isn't to convey facts, but to rekindle that lost enthusiasm for asking questions.

Gradual declassification of records has revealed that some of these nuclear incidents carried greater risk than was appreciated at the time. For example, it became clear only in 2002 that during the Cuban Missile Crisis, the USS Beale had depth-charged an unidentified submarine that was in fact Soviet and armed with nuclear weapons, and whose commanders argued over whether to retaliate with a nuclear torpedo.

I'll be the first to admit that we ultimately don't know what's going on exactly with quantum mechanics, and my personal guess... is that even quantum mechanics is probably an emergent theory, maybe an approximation of... something deeper. Maybe we can get it out of GU somehow, but... I also would guess... the opposite of Roger Penrose... that gravity doesn't really have much to do with this. I think you can... be in a spaceship far away... from any... important gravitating objects and do your little quantum experiments with a Schrödinger-like apparatus and you would get all the same fascinating things happening. So... ignoring gravity... ignoring relativistic effects altogether, you still have this thing people love fighting about. Does the wave function collapse or not, and that's why I'm so interested in this kind of discussion...
