It is positively spooky how the physicist finds the mathematician has been there before him or her.

In complexity, it is only simplicity that can be interesting.

In our universe we are tuned into the frequency that corresponds to physical reality. But there are an infinite number of parallel realities coexisting with us in the same room, although we cannot tune into them.

I'm offended by the kind of smarmy religiosity that's all around us, perhaps more in America than in Europe, and not really that harmful because it's not really that intense or even that serious, but just... you know after a while you get tired of hearing clergymen giving the invocation at various public celebrations and you feel, haven't we outgrown all this? Do we have to listen to this?

[Science] is corrosive of religious belief, and it's a good thing too.

All logical arguments can be defeated by the simple refusal to reason logically

Anything that we scientists can do to weaken the hold of religion, should be done and may, in fact, in the end, be our greatest contribution to civilization.
