For example, if you're not allowed to tear or glue, but just allowed to deform, then a coffee cup (which has a single hole) can be distorted and moulded into a ring doughnut, but can never be distorted and moulded into a ball, or a sugar bowl (which has two handles). There's no way to get rid of the hole, and there's no way to get a second hole. Topology comes in two flavours: "Point Set Topology" and "Algebraic Topology" Related topics are Braid Theory and Knot Theory. |
