If you look at the scientists who really make a difference, they think boldly. They're not afraid to question what they see.

I started out with a dream to make a star in a jar in my garage, and I ended up meeting the President of the United States!

When I hold something that's radioactive, it's kind of an indescribable feeling. It's kind of like when I'm with my girlfriend.

When I was 10 years old, that nuclear spark hit me. Whatever it may be, I really don't know what it was about nuclear science, but whatever it was that triggered that interest, it stuck. I went after that one with a passion.

The Fifties and Sixties were years of unreal optimism about weather forecasting. Newspapers and magazines were filled with hope for weather science, not just for prediction but for modification and control. Two technologies were maturing together: the digital computer and the space satellite.

We were making the first step out of the age of chemistry and physics, and into the age of biology.

If you take Darwinian theory, make a 'scientific' principle out of it, put it into political action, then you have something like Nazi Germany.

Reason, observation, and experience; the holy trinity of science.
