Topology
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Topology is the study of how objects are connected. It is divided into algebraic topology and geometric topology.
Topology has sometimes been called rubber-sheet geometry, because in topology there is no difference between a circle and a square (a circle made out of a rubber band can be stretched into a square) but there is a difference between a circle and a figure eight (you cannot stretch a figure eight into a circle without tearing). The spaces studied in topology are called topological spaces. They vary from familiar manifolds to some very exotic constructions.
