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

Quantum field theory, which was born just fifty years ago from the marriage of quantum mechanics with relativity, is a beautiful but not very robust child.

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

The whole history of the last thousands of years has been a history of religious persecutions and wars, pogroms, jihads, crusades. I find it all very regrettable, to say the least.

It is even harder to realize that this present universe has evolved from an unspeakably unfamiliar early condition, and faces a future extinction of endless cold or intolerable heat. The more the universe seems comprehensible, the more it seems pointless.

Most scientists I know don't care enough about religion even to call themselves atheists.

[C]reationists [and] other religious enthusiasts [are], in many parts of the world ..., the most dangerous adversaries of science.
