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

Everything that we know now will be changed in 10 years time.

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.

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'm not an academic, but I'm someone who has a great passion for science and wants to convey the idea that science is for everyone.

I'd missed science and what it was all about because I was too busy trying to think of other things, when I was at school. I was too busy trying to be James Dean.
