If you're an adult and you choose not to believe in science, fine, but please don't prevent your children from learning about it and letting them draw their own conclusions.

I like to regard myself as someone who's capable of critical thought, that is to say, who can evaluate claims.

NASA is an engine of innovation and inspiration as well as the world's premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget.

Everyone, red state, blue state, everyone supports space exploration.

The cosmical importance of this conclusion is profound and the possibilities it opens for the future very remarkable, greater in fact than any suggested before by science in the whole history of the human race.

I have been spending the better part of my professional life trying to create self-driving cars. At Google, I am working with a world-class team of engineers to turn science fiction into reality.

The thrill of science is the process. It's a social process. It's a process of collective discovery. It's debate, it's experimentation and it's verification of claims that might be false. It's the greatest foundation for a society.

We need to download scientific journals and upload them to file-sharing networks.
