Newton, Einstein, and every other great scientist in history...They all made mistakes. Of course they did. They're human! Science is a way to keep from fooling ourselves and each other.

I like seeing how people have succeeded when others would have presumed they would have failed, and others just go along with whatever everyone else does.

Who knows how dead Lazarus was? Was Lazarus decomposing in a six-foot grave when Jesus resurrected him? No, he wasn't.

I want to encourage people to not think in terms of gifts, but think in terms of, wow. You work hard to succeed at that, because that's exactly what I do.

Part of knowing how to think is knowing how the laws of nature shape the world around us. Without that knowledge, without that capacity to think, you can easily become a victim of people who seek to take advantage of you.

People say, oh we just need charismatic leaders to continue on to Mars. Now we've gone to the moon, of course Mars is next. No. Mars was never, of course, next. It is next if you think we went to the moon because we're explorers, but if you know we went to the moon because we were at war then we're never going to Mars. There's no military reason to do it, to justify the expenditure.
