We need more science in the world. Train me.

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.

The chances that your tombstone will read 'Killed by Asteroid' are about the same as they'd be for 'Killed in Airplane Crash.'

To view space as, "Well, let's go to Mars now," or "Let's do this now," maybe we should rethink of space as our backyard and have a suite of launch vehicles that can enable any ambition a person has regarding space. It's the same way you can go to buy a car: I want to go offroading, I'll buy this model. I'm a city driver, that's this model. I want to use less fuel, well, that's this model. They're not selling you one car, you have options. So when I think of space, I think of having options.

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

I object to religion in science classrooms not because it's religion but because it's not science.

I recognize that there's an appetite that I'm now serving, and I'm happy to do so. I think it means quite a bit that science has achieved this level of public interest and access. And so I'm simultaneously astonished every day upon recognizing this, and I think it's a good sign for the country and possibly for the world.
