Novelist Ian McEwan and theoretical physicist Nima Arkani-Hamed met at the Science Museum in London to mark the opening of the Large Hadron Collider exhibition. This is an edited extract of their conversation.
DO THE TWO CULTURES STILL EXIST?
IAN McEWAN: That old, two-culture matter is still with us, ever since [CP] Snow promulgated it back in the 50s. It still is possible to be a flourishing, public intellectual with absolutely no reference to science but it's happening less and less. And I think it's less a change of any decision in the culture at large, just a social reality pressing in on us. And it's true that climate change forces us to at least get a smattering of some idea of what it is to predict systems that have more than two or three variables and whether this is even possible. The internet has created sites like John Brockman's wonderful edge.org, where it's possible for laymen to sit in on conversations between scientists. And when scientists have to address each other out of their specialisms they have to speak plain English, they have to abandon their jargons, and we're the beneficiaries of that.
NIMA ARKANI-HAMED: It's an asymmetry that doesn't really need to exist. Certainly many scientists are very appreciative of the arts. The essential gulf is one of language and especially in theoretical physics, the basic difficulty is that most people don't understand our language of mathematics which we use to describe everything we know about the universe. And so while I'm capable of listening to and intensely enjoying a Beethoven sonata or an Ian McEwan novel it can be more difficult for people in the arts to have some appreciation for what we do. But at a deeper level there's a commonality between certain parts of the arts and certain parts of the sciences. ... MORE
