Posamentier (emeritus mathematics education, City College of New York) and Lehmann (mathematics, Humboldt U., Berlin) introduce students in nontechnical fields and general readers to some mathematical wonders, primarily through numerical and geometrical phenomena. Some of the phenomena can prove useful in arithmetic, but others are presented to help overcome the fear of mathematics instilled in so many people by elementary school teachers.
