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

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.

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've found the thing in life that I adore, which is working in science television. It's just a big adventure, really.

You don't have to be musician to listen to music, and you don't have to be a filmmaker to go to the cinema, but somehow when we think of science, we think of it only as an academic discipline.

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."

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