A lecture on the mathematics behind shapes; moving from the counting of edges and faces to complex modern topology.
If we count the number of vertices, v, on a cube, v = 8, number of edges e = 12, and number of faces f = 6, then v¬ – e + f = 2. The same is true for a tetrahedron where v¬ = 4, e = 6 and f = 4. In fact, the mathematician Leonhard Euler obtained the amazing result that v¬ – e + f = 2 for a wide class of polyhedrons. This theorem of Euler is a result in topology, a subject which tries to find those properties of geometrical objects that are invariant under continuous deformation – a tetrahedron can be changed in this way into a cube. Topology is sometimes called rubber sheet geometry.
