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!"

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.

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've always been a bit of a dreamer. I've always loved to look and seek, and explore and find out.

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.

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