When you get to the end of all the light you know and it's time to step into the darkness of the unknown, faith is knowing that one of two things shall happen: either you will be given something solid to stand on, or you will be taught how to fly.

Today's science is tomorrow's technology.

Most people avoid thinking if they can, some of us are addicted to thinking, but Von Neumann actually enjoyed thinking, maybe even to the exclusion of everything else.

Science attempts to find logic and simplicity in nature. Mathematics attempts to establish order and simplicity in human thought.

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.
