The Coarse Course

Coarse geometry is...

...what you see when you screw up your eyes. Take an impressionist painting. Up close it doen't make any sense, but from far away it seems to have lots of detail. Now move the painting further and further away, off towards infinity. If the image is infinitely large, then it will still have structure and geometry in the limit; this is the coarse geometry of the image.
