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.

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.

People think of science like somehow that's the answer, and that it's all about right answers, but science is a lens that we look at the world through.

Everything that we know now will be changed in 10 years time.

Newton had a very good description of gravity, back in the day, and then Einstein came along and dug a little bit deeper. Science is like peeling an onion. You go deeper and deeper and deeper, and it doesn't stop. It's not like you will get to a right answer.

If you go through life and actually get to find out the thing you want to do, you're very lucky.
