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

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.’

Hard to find anything lovelier than a tree. They grow at right angles to a tangent of the nominal sphere of the Earth.

I want mechanical engineers to make better transportation systems. I want chemical engineers to develop better solar panels, and so on.

You start doing the addictive behavior to feel good and then your receptors get overloaded with dopamine, then you stop doing the addictive thing and some of the receptors have shut down and you don’t have enough dopamine to feel good.

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

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).

One of the drawbacks of English is you can’t spell things by hearing them.

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.

There are just two people entitled to refer to themselves as “we”; one is the editor and the other is the fellow with a tapeworm.

Educated women have fewer kids. And the kids they do have are better cared for and are more successful. As I like to say, it’s not one thing that we need to focus on. It’s everything all at once.

If you have this idea that the earth is only 6,000 years old, you are denying, if you will, everything that you can touch and see. Youre not paying attention to whats happening in the universe around you.

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.

We are part of the process; we are the exquisite result of billions of years of natural research and development.

I’ll admit that the discovery of evolution is humbling, but it is also empowering. It transforms our relationship to the life around us. Instead of being outsiders watching the natural world go by, we are insiders.

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.

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.

Faith does not ignore the facts, it ignores the power of the facts.

Welcome to prekindergarten! You will not die if you discover that there are more lines out there than just your own. In fact, you’ll discover that you will have an advantage if you know more of them!

In fact, I might be confident for the human race because of what the human race has given me. When I was in the street and bars, people always came up to me and said, “Don’t stop, keep going.”

What gave transcendent importance to the aggressiveness of power was the fact that its natural prey, its necessary victim, was liberty, or law, or right.

I know that New York is big, there are huge buildings, but in fact, it’s quite small and contained.

The fact that the ministerial conspiracy against liberty had risen from corruption was of the utmost importance to the colonists.

There is nothing better to display the truth in an excellent light, than a clear and simple statement of facts.

The fact that we don’t read more books in America can be traced squarely to the fact that we have newspapers that are about a hundred times as big as the newspapers anywhere else.
