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.

We do not believe any group of men adequate enough or wise enough to operate without scrutiny or without criticism.

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.
