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

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.

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 wasn't naturally a scientist, but I was always fascinated by how the world worked and why things were the way they were.

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.

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