We have the media, which is such a waste in the sense that you can actually feel your IQ get lower as you watch TV.

You can mass-produce hardware; you cannot mass-produce software - you cannot mass-produce the human mind.

Chemistry is the melodies you can play on vibrating strings.

If all our common-sense notions about the universe were correct, then science would have solved the secrets of the universe thousands of years ago. The purpose of science is to peel back the layer of the appearance of the objects to reveal their underlying nature. In fact, if appearance and essence were the same thing, there would be no need for science.

I want to see us to explore outer space. But I want to do it safely, without the loss of human life, and democratically: where is the free-wheeling debate on this question?

One force is more powerful than plutonium, the spirit of the American people united.
