From cow to sphere to donut. The natural progression of scientific abstraction. In reality, we have a standard dairy cow. Physics simplifies it to a spherical cow with uniform density (because physicists can't be bothered with anatomical details when calculating gravitational fields). Then mathematics takes it further with a topological transformation into a torus—because in topology, a coffee mug and a donut are identical. Seven years of graduate school just to learn that everything is either a point, a sphere, or a donut with various numbers of holes.
Topology To Be Specific
