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

Those people who are scared of science or are a bit dismissive of science tend to not really understand what science really is, which is the most beautiful, most elegant and most creative way of looking at the world.

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

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."

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.

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.

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.
