The philosophy of science is inherent in the process. This is to say, you think critically, you draw a conclusion based on evidence, but we all pursue discovery based on our observations. That's where science starts.

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.

As my old professor Carl Sagan said so often, 'When you’re in love, you want to tell the world.’ And I base my beliefs on the information and the process that we call science. It fills me with joy to make discoveries every day of things I’ve never seen before. It fills me with joy to know that we can pursue these answers. It is an astonishing thing that we are — you and I are one of the ways the universe knows itself.

I used to play ultimate Frisbee, and I just got a reputation for making popcorn at parties. I don't mean to brag on myself, but I make the popcorn in the pot, and it comes out fine every time.

That's what makes a human a human, if we store information outside our bodies.

Everybody remembers numbers and computers remember numbers. People remember procedures and computers certainly remember procedures. But the other thing that's still important is that your perception as a human is affected subtly by all this stuff that you can't quite articulate. You run your life according to all this stuff that's happened to you. All of your memories affect everything you do whereas with a computer, there's adaptive software and things, but it's more literal.

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.
