Say you have a genus-2 surface and a diffeomorphism of that surface to itself, then you can make a 3-manifold by crossing that surface with the unit interval to form a “cylinder” and then use the diffeomorphism to glue one end of the cylinder to the other. Thurston showed that ...

For my research day job, I solve differential equations on computers. I do this by appropriating many of the special functions of mathematical physics to keep track of all kinds of information in numerical form. But looking at the inner workings of those functions leads to the striking observation: spherical ...
