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

There is so much wonder and joy in science, about understanding how the world works and why the world is the way it is. It's not just for academics. It is a thing that's available to everyone.

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

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.

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!"

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.

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.
