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

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.

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.

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.

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.

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."
