The universe is an enormous direct product of representations of symmetry groups.

A theorist today is hardly considered respectable if he or she has not introduced at least one new particle for which there is no experimental evidence.

The more we refine our understanding of God to make the concept plausible, the more it seems pointless.

The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy.

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.

It appears that anything you say about the way that theory and experiment may interact is likely to be correct, and anything you say about the way that theory and experiment must interact is likely to be wrong.

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