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.

Science can and should inform debate about abortion and the law. But science does not resolve questions of moral value and moral choice.

In any genre you're working in, you can always find a way to tell a particular kind of story. I love fantasy; I love science fiction. I love all kinds of fiction, in fact.

I invented an algorithm for starting micro turbo-molecular vacuum pumps to be used in science instruments on a future Mars rover.

Myself, I have a philosophy degree and a fake computer-science degree. I say fake because I really didn't learn anything.
