"This book explores the application of a broad range of mathematical techniques to the solution of Euclidean problems"--

This book discusses 24 unsolved problems in number theory and geometry.

The audience for this book includes just about anyone who has any curiosity at all about how mathematics helps in explaining the world."--Paul J. Nahin, author of An Imaginary Tale "I learned a lot from this book.

An exploration of the mathematics of twenty geometric diagrams that play a crucial role in visualizing mathematical proofs.

This lavishly illustrated book provides an unusually accessible approach to geometry by placing it in historical context.

This text is for a one-semester undergraduate course on geometry. It is richly illustrated and contains hundreds of exercises.
