You don't have to be musician to listen to music, and you don't have to be a filmmaker to go to the cinema, but somehow when we think of science, we think of it only as an academic discipline.

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.

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

Yeah. Science doesn't end. That's the one thing I learned. People think of science as spitting out right answers, and that's it. It's always under review.

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 love being in America. I love America. I absolutely adore working in America. I'm at my happiest when I'm in the States.

We've only had aircrafts for a hundred years, and yet look at us. So, I've become absolutely fascinated by this strange, bizarre world of airports, air travel and transportation. It's interesting.
