When I was acting, as a hobby, I would devour popular science books and keep up-to-date about what was going on in the science community. And then, suddenly my hobby became my job. I didn't one day say, "I'm not acting. I'm now going to be a science person."

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.

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

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

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.

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.

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