There are children playing in the streets who could solve some of my top problems in physics, because they have modes of sensory perception that I lost long ago.

I remembered the line from the Hindu scripture, the Bhagavad-Gita... "Now I am become Death, the destroyer of worlds." I suppose we all thought that, one way or another.

In some sort of crude sense, which no vulgarity, no humor, no overstatement can quite extinguish, the physicists have known sin; and this is a knowledge which they cannot lose.

Both the man of science and the man of action live always at the edge of mystery, surrounded by it.

All history teaches us that these questions that we think the pressing ones will be transmuted before they are answered, that they will be replaced by others, and that the very process of discovery will shatter the concepts that we today use to describe our puzzlement.

We know too much for one man to know too much.

The powerful notion of entropy, which comes from a very special branch of physics … is certainly useful in the study of communication and quite helpful when applied in the theory of language.
