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.

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

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!"

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

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.

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.

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