Title of Talk | Escher's World and Green Jello World - A Concrete Introduction to Hyperbolic Geometry |
Abstract | Understanding theorems in non-Euclidean Geometry can be challenging to people who live in a Euclidean World. Since we do live on a sphere, Elliptic geometry makes some sense, but Hyperbolic geometry completely defies all our intuition. I will present two concrete examples of Poincare's models, which in class I refer to as "Escher's World" and the "Green Jello World". Thinking about what the inhabitants of these worlds might consider to be a straight line and other geometric concepts lets students accept the fact that Hyperbolic geometry is in fact just as natural as Euclidean Geometry. |
