We are just a speck, on a speck, orbiting a speck, in the corner of a speck, in the middle of nowhere.

The information you get from social media is not a substitute for academic discipline at all.

We need them. We need scientifically literate voters and taxpayers for the future.

The theory of evolution was not formally published until shortly before Faraday's death. Evolution was yet to be discovered during Faraday's life. Also, I don't think that Michael Faraday would claim that the Earth is extraordinarily young.

I've always loved airplanes and flight. The space program was really important to me as a kid. I still have a photo of Armstrong and Aldrin on the moon in my living room.

Not wasting any water bottles is good. Not leaving the lights on is good. Turning the thermostat down in the winter, up in the summer, is good. But the best thing any of us in the developed world, especially in the United States, can be doing is talking about it.

I say to the grown-ups, 'If you want to deny evolution and live in your world that's completely inconsistent with everything we've observed in the universe that's fine. But don't make your kids do it.'
