"This is a book of elementary geometric topology, in which geometry,
frequently illustrated, guides calculation. The book starts with a wealth of examples,
often subtle, of how to be mathematically certain whether two objects are the same from
the point of view of topology."
"After introducing surfaces, such as the Klein bottle, the book explores
the properties of polyhedra drawn on these surfaces. More refined tools are developed in a
chapter on winding number, and an appendix gives a glimpse of knot theory.
Moreover, in this revised edition, a new section gives a geometrical
description of part of the Classification Theorem for surfaces. Several striking new
pictures show how given a sphere with any number of ordinary handles and at least one
Klein handle, all the ordinary handles can be converted into Klein handles."
Numerous examples and exercises make this a useful textbook for a first
undergraduate course in topology, providing a firm geometrical foundation for further
study.
