There's nothing I believe in more strongly than getting young people interested in science and engineering, for a better tomorrow, for all humankind.

If you just take a single human and put him or her in the forest he or she might not do very well without some sort of education which he got or she got from some tribe.

Television isn't inherently good or bad. You go to a bookstore, there are how many thousands of books, but how many of those do you want? Five? Television's the same way. If you're going to show people stuff, television is the way to go. Words and pictures show things.

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.

We are special in the sense that we can know our place in the cosmos. We can know our place in space. We are at least one of the cosmos's ways of knowing itself. That fills me with reverence and joy. Another insight I really want people to consider is this: everyone has gotten this far. Everyone you meet has made it this far. Nobody is superior to anyone else from an evolutionary standpoint.

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.
