Much of topology is aimed at exploring abstract versions of geometrical objects in our world. The concept of geometrical abstraction dates back at least to the time of Euclid. All of the objects that we will study in this note will be subsets of the Euclidean spaces. Topics covered includes: 2-manifolds, Fundamental group and covering spaces, Homology, Point-Set Topology, Group Theory, Graph Theory and The Jordan Curve Theorem.
