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.

If you go through life and actually get to find out the thing you want to do, you're very lucky.

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

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

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.

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