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

The natural world is a package deal; you don't get to select which facts you like and which you don't.

No matter what you may believe spiritually or otherwise, the Earth is clearly not 6,000 or 10,000 years old.

The most serious problem facing humankind is climate change. All of these people breathing and burning our atmosphere has led to an extraordinarily dangerous situation. I hope next generation will emerge and produce technology, regulations, and a worldview that enable as many of us as possible to live happy healthy lives.

I say to the grownups, if you want to deny evolution and live in your world, that's completely inconsistent with the world we observe, that's fine. But don't make your kids do it. Because we need them. We need scientifically literate voters and taxpayers for the future. We need engineers that can build stuff and solve problems.

I've got no problem with anybody's religion. But if you go claiming the Earth is only 10,000 years old, that's just wrong.

If you meet somebody who says he or she has never dreamed of flying, I don't believe you. I mean, they're lying.
