Harold Jacobs’s Geometry created a revolution in the approach to teaching this subject, one that gave rise to many ideas now seen in the NCTM Standards. Since its publication nearly one million students have used this legendary text. Suitable for either classroom use or self-paced study, it uses innovative discussions, cartoons, anecdotes, examples, and exercises that unfailingly capture and hold student interest. This edition is the Jacobs for a new generation. It has all the features that have kept the text in class by itself for nearly 3 decades, all in a thoroughly revised, full-color presentation that shows today’s students how fun geometry can be. The text remains proof-based although the presentation is in the less formal paragraph format. The approach focuses on guided discovery to help students develop geometric intuition.

In 1952, Martin Gardner wrote the book Fads and Fallacies in the Name of Science, which has become a modern classic of the skeptical movement. He is best known as the Father of Recreational Mathematics, but was also a frank critic of pseudoscientists and a contributor to the Skeptical Inquirer magazine.Marcello Truzzi was one of the founders of the Committee for the Scientific Investigation of Claims of the Paranormal in 1976. He left that and founded the Center for Scientific Anomalies Research, which was more aligned with his views.Dana Richards presents the unedited, colorful correspondence between these two well-known figures within the skeptical movement as they probed and wrestled with fundamental questions such as:
