Topologists like to break up complicated objects into small, manageable pieces. As a simple example, a natural way to split the surface of the earth is to divide it into two pieces, the Northern and Southern Hemispheres. Of course, the earth's surface can also be cut into many more components, and a natural question is to determine how each of these decompositions is related to any other. We consider the problem of cutting up a sphere into topological puzzle pieces in dimension two, three, and four, describing some recent progress (joint with Jeffrey Meier) on a big, unsolved problem in this area.
