Speaking of human computers, there is a guy named Art Benjamin, he's a human calculator. He says it's a skill he learned as a kid. Now he's a math professor at Harvey Mudd. He can find the square root of a six digit number in a few seconds. Practice.

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.

When we explore the cosmos, we come to believe and prove that we can solve problems that have never been solved. It brings out the best in us. Space exploration imbues everyone with an optimistic view of the future.

Along with the evidence of common sense, researchers have proven scientifically that humans are all one people. We're a lot like dogs in that regard. If a Great Dane interacts (can we say interact?) with a Chihuahua, you get a dog.

You stop planetary exploration, those people who do that extraordinary work are going to have to go do something else.

Evolution is a theory, and it's a theory that you can test. We've tested evolution in many ways. You can't present good evidence that says evolution is not a fact.
