Today's science is tomorrow's technology.

I think that intellectuals who end up in hell will have to read page proofs and check indexes there.

The scientist is not responsible for the laws of nature. It is his job to find out how these laws operate. It is the scientist's job to find the ways in which these laws can serve the human will. However, it is not the scientist's job to determine whether a hydrogen bomb should be constructed, whether it should be used, or how it should be used. This responsibility rests with the American people and with their chosen representatives.

The main purpose of science is simplicity and as we understand more things, everything is becoming simpler.

I am guilty of the great crime of optimism.

Physics is, hopefully, simple. Physicists are not.

One may say that predictions are dangerous particularly for the future. If the danger involved in a prediction is not incurred, no consequence follows and the uncertainty principle is not violated.
