The Universe revealed by science is one of far more awesome grandeur than any religion has ever posited.

Science is nothing more than a neverending search for the truth.

We batter this planet as if we had someplace else to go.

Carl took on the military-industrial complex. He campaigned around the world for an end to the production of weapons of mass destruction. To him it was a perversion of science.

This planet seems to be in such sorry shape. And I can't ever think about the rest of the universe without coming back home and thinking what the implications for life here would be if we were to really have some definitive proof of extraterrestrial life.

I found that it was easiest to convey the information in the context of the life of the scientist or in the context of our own personal experience, and there was no idea that was too complicated that couldn't be explained clearly and directly.

My knowledge of science came from being with Carl, not from formal academic training. Carl gave me a thrilling tutorial in science and math that lasted the 20 years we were together.
