We investigate the five Platonic solids: tetrahedron, cube, octohedron, icosahedron and dodecahedron. Euler's formula relates the number of vertices, edges and faces. We give a proof using a triangulation argument and the flow down a sphere.

This is the eighth lecture in this beginner's course on Algebraic Topology, given by Assoc Prof N J Wildberger of the School of Mathematics and Statistics at UNSW.

  • Is the process of finding a non-trivial theorem an NP-Complete problem?

  • This really helped me, thank you very much. Btw, you sound like Alex Trebek.

  • Would someone please put all AlgTop# lectures in a playlist for us? That would be sweet.
