Newton had a very good description of gravity, back in the day, and then Einstein came along and dug a little bit deeper. Science is like peeling an onion. You go deeper and deeper and deeper, and it doesn't stop. It's not like you will get to a right answer.

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

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

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

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.
