Topology Illustrated

Please click "Look inside" and read Section 1.1 Topology around us.
The book contains over 1000 color illustrations and over 1000 exercises.
Algebraic topology is the main subject of this book that initially follows a two-semester first course in topology. It furthermore takes the reader to more advanced parts of algebraic topology as well as some applications: the shape of the universe, configuration spaces, digital image analysis, data analysis, social choice, exchange economy. An overview of discrete calculus is also included (extended presentation in Calculus Illustrated. Volume 1: Precalculus).
