`This book is designed to introduce a student to some of the important ideas of algebraic topology by emphasizing the relations of these ideas with other areas of mathematics. Rather than choosing one point of view of modern topology ..., we concentrate our attention on concrete problems in low dimensions, introducing only as much algebraic machinery as necessary for the problems we meet. This makes it possible to see a wider variety of important features of the subject than is usual in a beginning text. The book is designed for students of mathematics or science who are not aiming to become practicing algebraic topologists... We also feel that this approach is in better harmony with the historical development of the subject.... We have tried to do this without assuming a graduate-level knowledge or sophistication.

`Algebraic topology can be thought of as the study of the shapes of geometric objects. It is sometimes referred to in popular accounts as ``rubber-sheet geometry''. In practice this means we are looking for properties of spaces that are unchanged when one space is deformed into another.
