David S. Richeson is associate professor of mathematics at Dickinson College.
Winner of the 2010 Euler Book Prize, Mathematical Association of America One of Choice's Outstanding Academic Titles for 2009 The author has achieved a remarkable feat, introducing a nave reader to a rich history without compromising the insights and without leaving out a delicious detail. Furthermore, he describes the development of topology from a suggestion by Gottfried Leibniz to its algebraic formulation by Emmy Noether, relating all to Euler's formula. This book will be valuable to every library with patrons looking for an awe-inspiring experience. -- Choice This is an excellent book about a great man and a timeless formula. --Charles Ashbacher, Journal of Recreational Mathematics I liked Richeson's style of writing. He is enthusiastic and humorous. It was a pleasure reading this book, and I recommend it to everyone who is not afraid of mathematical arguments and has ever wondered what this field of 'rubbersheet geometry' is about. You will not be disappointed. --Jeanine Daems, Mathematical Intelligencer The book is a pleasure to read for professional mathematicians, students of mathematicians or anyone with a general interest in mathematics. -- European Mathematical Society Newsletter I found much more to like than to criticize in Euler's Gem. At its best, the book succeeds at showing the reader a lot of attractive mathematics with a well-chosen level of technical detail. I recommend it both to professional mathematicians and to their seatmates. --Jeremy L. Martin, Notices of the AMS I highly recommend this book for teachers interested in geometry or topology, particularly for university faculty. The examples, proofs, and historical anecdotes are interesting, informative, and useful for encouraging classroom discussions. Advanced students will also glimpse the broad horizons of mathematics by reading (and working through) the book. --Dustin L. Jones, Mathematics Teacher The book should interest non-mathematicians as well as mathematicians. It is written in a lively way, mathematical properties are explained well and several biographical details are included. --Krzysztof Ciesielski, Mathematical Reviews
