Things which stimulate my curiosity are pretty far removed from the practical and therefore from classification.

The general notions about human understanding...which are illustrated by discoveries in atomic physics are not in the nature of things wholly unfamiliar, wholly unheard of, or new. Even in our own culture, they have a history, and in Buddhist and Hindu thought a more considerable and central place. What we shall find is an exemplification, an encouragement, and a refinement of old wisdom.

It is a profound and necessary truth that the deep things in science are not found because they are useful; they are found because it was possible to find them.

The atomic bomb made the prospect of future war unendurable. It has led us up those last few steps to the mountain pass; and beyond there is a different country.

Any man whose errors take ten years to correct is quite a man.

No man should escape our universities without knowing how little he knows.

Maybe General Groves was right. Maybe we should just banish thinking forever.
