July 25, 2011
July 25, 2011, Greencastle, Ind. — Roger B. Nelsen, professor emeritus of mathematics at Lewis & Clark College and 1964 graduate of DePauw University, is co-author of Icons of Mathematics: An Exploration of Twenty Key Images. Published by the Mathematical Association of America, the book presents and "exploration of the mathematics of twenty geometric diagrams that play a crucial role in visualizing mathematical proofs," notes a synopsis. "Those teaching undergraduate mathematics will find material here for problem solving sessions, as well as enrichment material for courses on proofs and mathematical reasoning."
"Images, whether real or in the imagination, are a foundational component of mathematics," notes Charles Ashbacher, editor of the Journal of Recreational Mathematics. He calls the book "an excellent study item to prepare high school teachers of geometry. People currently teaching high school geometry will find it a valuable resource for more challenging problems to present to the 
students. Others with just an interest in geometry will find it worthy of an in-depth look."
