The more you find out about the world, the more opportunities there are to laugh at it.

To leave the world better than you found it, sometimes you have to pick up other people's trash.

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.

The oncoming trouble I speak of is climate change. It's going to affect all of you in the same way the Second World War consumed people of my parent's generation.

Religion is a completely different thing from the claim that the Earth is six thousand years old. That's just crazy.

Talk about science with everyone you meet. Especially talk about climate change. It needs to become a part of our everyday conversation (the way it is everywhere else in the world).

I understand that you take the Bible, as written in English, translated many many times over the last three millennia as to be a more accurate, more reasonable assessment of the natural laws we see around us than what I and everybody in here can observe. That, to me, is unsettling.
