A book describing how visualization techniques can be used in understanding and teaching mathematics.

This book presents techniques for proving a variety of mathematical results in three-dimensional Euclidean space, the field traditionally known as solid geometry. The text is aimed at secondary school and college and university teachers as an introduction to solid geometry, or in a mathematics course for liberal arts students.

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

A collection of remarkable proofs that are exceptionally elegant, and thus invite the reader to enjoy the beauty of mathematics.

A collection of articles introducing the core ideas of calculus. A resource for teachers of secondary school and undergraduate students.
