Knots and Surfaces

In most mathematics textbooks, the most exciting part of mathematics - the process of invention and discovery - is completely hidden from the reader. The aim of Groups and Symmetry and Knots and Surfaces is to change all that. By means of a series of carefully selected tasks, these books lead readers to discover some real mathematics. There are no formulas to memorize; no procedures to follow. The books are guides: their job is to start you in the right direction and to
bring you back if you stray too far. Discovery is left to you.
