[Chemistry] laboratory work was my first challenge. ... I still carry the scars of my first discovery-that test-tubes are fragile.

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.

A state-of-the-art calculation requires 100 hours of CPU time on the state-of-the-art computer, independent of the decade.

The science of today is the technology of tomorrow.

The extinction of the human race will come from its inability to EMOTIONALLY comprehend the exponential function.

If not for me, the H-bomb would have been developed in Russia first. In the U.S., we'd now be speaking Russian.

Today's science is tomorrow's technology.
