The only gratification that science denies to us is deception.

People think that if you are a scientist you have to give up that joy of discovery, that passion, that sense of the great romance of life. I say thats completely opposite of the truth.

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.

The way he treated me & the way I treated him, the way we took care of each other & our family, while he lived. That is so much more important than the idea I will see him someday.

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

The greatest thing that science teaches you is the law of unintended consequences.

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.
