Richard Powers - where fact and fiction collide (Essay - What Does Fiction Know?)

One of my very favorite writers, Richard Powers, who writes at the intersection of fiction and science, has written an inspiring essay about the city of Berlin, the unreliability of storytellers, and the place where fiction and fact collide. It is inspiring for the way it mixes personal experience, data, and artifice. It appeared in last summer's Design Observer and I link it here.
