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

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

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

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."

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.

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.
