A lot of my work has been about stuff I've been frightened of: cliffs, explosions, meteorites, that kind of stuff. I would have been this trembling blob of fear if I hadn't got into making art, which is a good way of deferring it.

To make large, site-specific work as an artist is usually quite tortuous; there are so many boxes you have to tick.

People often want the big dramatic works, not the smaller quieter ones, but I don't worry about how it fits together anymore; I just have to do it. I feel compelled to make a work: it's like an itch I have to scratch, and once it's been scratched, it goes away.

Who thought it would be a good idea to undermine art in the school curriculum? Who thought studying the history of our visual culture was a waste of time? Who thought that only private schools should have that privilege? Was it someone who said we don't need experts?

Artists and scientists are very close. They always have been, but I think we've just been divided out over the last few centuries into specialisms. Leonardo da Vinci was drawing helicopters and all kinds of things. We're artificially divided. I think we're closer than we think we are.
