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.

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

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

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.

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

Statistically, 2012 was the safest year to travel on a plane, in the history of aviation. Not one major passenger plane crashed. It's pretty amazing. And when you see them being taken apart and you see the work that goes into keeping those things in the air, you think, "Wow!"

I wasn't naturally a scientist, but I was always fascinated by how the world worked and why things were the way they were.
