(Hopefully) Interesting links
  • The Mobius Strip. On the right is Escher's 1963 woodcut of ants crawling round the strip - appropriate considering our obsession with intrinsic geometry...
  • An excellent page on hyperbolic geometry and art
  • Stuff on Black holes
  • Parallel transport on the sphere applet
  • Parallel transport on a torus
  • Just in case you thought that Relativity was the only place differential geometry was used, here is some more Physics
  • The Mean curvature flow and other delights
