Topology is a relatively young and very important branch of mathematics which studies properties of objects which are preserved through deformations, twistings, and stretchings, but not tearing. This book is well suited as preparation for students who plan to take a course in algebraic topology but also for advanced undergraduates or beginning graduates to just find out what topology is all about. The book has more than 200 problems, plenty of examples, and over 200 illustrations.
