“I stand by my assertions that although you can know what happens to any individual species that you modify, you cannot be certain what will happen to the ecosystem.”

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.

I feel that I’ve often pointed out that there are countless aspects of life and nature that scientists and scientific thinkers cannot explain.
