I like to regard myself as someone who's capable of critical thought, that is to say, who can evaluate claims.

I tell personal stories associated with aspects of the theory, and I hope they are interesting and compelling. I don't feel you're going to change a grownup's mind in one reading. People have to be exposed to scientific ideas over and over again for years. It's also not a textbook.

We are just a speck, on a speck, orbiting a speck, in the corner of a speck, in the middle of nowhere.

If we raise a generation of students who dont believe in the process of science, who think everything that weve come to know about nature and the universe can be dismissed by a few sentences translated into English from some ancient text, youre not going to continue to innovate.

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).

Millennial voters are very concerned about climate change and will vote for candidates who are planning to address it. But the systems that are in place - people talk about gerrymandering and the money that's in politics, this is a real thing, a real effect - and it's hard for climate change-denying legislators to get voted out. But I predict it will happen.

The oncoming trouble I speak of is climate change. It's going to affect all of you in the same way the Second World War consumed people of my parent's generation.
