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.

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

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

I was very much the laymen, trying to find stuff out because I'm curious about the world.

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.

I'm not an academic, but I'm someone who has a great passion for science and wants to convey the idea that science is for everyone.

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!"
