The science of today is the technology of tomorrow.

Had we not pursued the hydrogen bomb, there is a very real threat that we would now all be speaking Russian. I have no regrets.

Life improves slowly and goes wrong fast, and only catastrophe is clearly visible.

There is a time for scientists and movie stars and those who have flown the atlantic to restrain their opinions lest they be taken more seriously than they should be.

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.

U.S. has lost a battle more important and greater than Pearl Harbor.

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.
