A fact is a simple statement that everyone believes. It is innocent, unless found guilty. A hypothesis is a novel suggestion that no one wants to believe. It is guilty, until found effective.

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.

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.

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

Physics is, hopefully, simple. Physicists are not.

No endeavor that is worthwhile is simple in prospect; if it is right, it will be simple in retrospect.

My experience has been in a short 77 years that in the end when you fight for a desperate cause and have good reasons to fight, you usually win.
