60-Second Adventures in Thought

I came up with something like the grandfather paradox when I was a kid. Say you go back in time to prevent the assassination of JFK. Once you've prevented him from being assassinated, naturally enough, you would've had no reason to go back in time to prevent his assassination, and thus never would have gone.

The grandfather paradox is, however, much better stated.

Schrodinger was attempting to mock the theory of quantum mechanics with his paradox. However, quantum mechanics doesn't really have effects at the macro level. If you repeated his experiment, there would not be a simultaneously alive and dead cat in the box. That's nonsense.

It's the Pauli Exclusion Principle which is the most mind boggling of all!! Before anyone says something, yes he said energy levels instead of quantum states but that was because he was trying to keep it simple for a celebrity audience.
