The physicists have known sin; and this is a knowledge which they cannot lose.

When all thermonuclear sources of energy are exhausted a sufficiently heavy star will collapse. Unless fission due to rotation, the radiation of mass, or the blowing off of mass by radiation, reduce the star's mass to the order of that of the sun, this contraction will continue indefinitely.

When we deny the EVIL within ourselves, we dehumanize ourselves, and we deprive ourselves not only of our own destiny but of any possibility of dealing with the EVIL of others.

There must be no barriers to freedom of inquiry... There is no place for dogma in science. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors. Our political life is also predicated on openness. We know that the only way to avoid error is to detect it and that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost, and science can never regress.

We know that the wages of secrecy are corruption. We know that in secrecy error, undetected, will flourish and subvert.

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.
