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.

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

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.

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

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

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 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.
