I think the role of the artist today is about being provocative. I don't mean shocking, but you have to provoke people into action. As an artist, you ask people for their time. It's the most precious thing anyone has. I'm asking audiences to come to my work and spend some time with it. What I'm really doing, of course, is asking people to take time for themselves.

When I was doing mainly music, I used to stick a microphone out the window, into the countryside, and create a live mix. I wanted to put air in electronic music. I record the sounds of twigs, barks, and stones. I've always been obsessed with the idea of combining the natural and the man-made. It's not because I think the technology is crap, or that I'm trying to work against it, but that juxtaposition is truly beautiful. The question of what is natural and unnatural is very open.

I find flying interesting in that it's a very intimate experience. You're so close, physically, to one or two other people and you eat, sleep, do everything together. I've met the most extraordinary people on planes, some of whom I've stayed in touch with, some I haven't. Even if you're beside someone who ignores you for eight hours, there's a physicality you wouldn't put up with from anyone other than someone you knew well. You're in it together, even if you never say a word to one another.

People often think of artists and scientists as being diametrically opposed, but we both believe something is possible. We have a hypothesis and then we do everything to make it possible, but we don't know if it's possible! All the scientists I've worked with have a natural, easy fit with me. The solutions they find are truly creative. All scientists, in some way, are artists.
