I've never felt scared of flight, ever. It's really weird. I don't know. They stick a gin and tonic in your hands and I just think, "Life is good!"

At the heart of science is experimentation. Science doesn't care what you think. What's important is experimenting and actually working stuff out.

In my lifetime, the population of the world has doubled.

The thing I loved, particularly, was the mystery of science and the idea that science doesn't know all the answers, but it is a process of finding out. It's not like science will give you the right answer and science knows everything. I love the mysteries of it.

I'd missed science and what it was all about because I was too busy trying to think of other things, when I was at school. I was too busy trying to be James Dean.

I was awful at science at school, as a subject, because I didn't have the discipline. But, I was awful at music, as well, and I loved music.

Yeah. Science doesn't end. That's the one thing I learned. People think of science as spitting out right answers, and that's it. It's always under review.
