Nothing in physics seems so hopeful to as the idea that it is possible for a theory to have a high degree of symmetry was hidden from us in everyday life. The physicist's task is to find this deeper symmetry.

Our mistake is not that we take our theories too seriously, but that we do not take them seriously enough.

A physicist friend of mine once said that in facing death, he drew some consolation from the reflection that he would never again have to look up the word "hermeneutics" in the dictionary.

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.

The invisible and the non-existent look very much alike.

I have a friend — or had a friend, now dead — Abdus Salam, a very devout Muslim, who was trying to bring science into the universities in the Gulf states and he told me that he had a terrible time because, although they were very receptive to technology, they felt that science would be a corrosive to religious belief, and they were worried about it… and damn it, I think they were right. It is corrosive of religious belief, and it’s a good thing too.

It does not matter whether you win or lose, what matters is whether I win or lose!
