## Benjamin Franklin's Numbers: |

"Making frequent use of Franklin's writings as well as mathematical brainteasers of the type that Franklin enjoyed, "I thoroughly enjoyed reading this book. It is written in a pleasant, conversational style and the author's enthusiasm for his subject is infectious. The text is richly embroidered with colorful details, both mathematical and historical." "Pasles has succeeded in writing a book dealing with mathematics that is accessible to readers at all levels, yet thoroughly referenced and scholarly enough to satisfy researchers. His endeavor was eased by the fact that the bulk of the material concerns Franklin's magic squares and circles, which only require that the reader have the ability to add. Unexpectedly, Pasles contributes much that is new; he corrects the errors of previous authors and presents new ideas through literary sleuthing and mathematical analysis." "Pasles makes a convincing case for Franklin as the last true Renaissance man in what is an entertaining and informative book that will even appeal to readers with only limited knowledge of mathematics." "With seven years of diligent study, by going through a vast amount of archive material, references including primary sources and books and research papers, the author has produced a carefully documented and fascinating account to substantiate the theme he makes, namely, that Franklin 'possessed a mathematical mind.'" "[Paul C. Pasles] and the publisher should . . . be commended for producing a highly aesthetically pleasing book, with a color centerpiece showing many of Franklin's beloved magic squares in their full glory." "This book will appeal to readers with an interdisciplinary interest in both history and mathematics. Teachers who enjoy showing students the many ways in which they can draw on mathematics to construct logical, real-world arguments will find useful examples for the classroom. The book also includes a variety of number puzzles that can be used to challenge students." "I found
"Here's a book like no other, in which the life and times of Benjamin Franklin are viewed through a mathematical lens. It is at once lively and scholarly, and contains much fascinating material that will be new to mathematicians, historians, and everyone else. Did you know that the success of the American Revolution may have depended on magic squares? Paul Pasles tells why. Don't worry--the book is equation free." "As a mathematician and Philadelphian, I was delighted to learn of how extensive were Franklin's contributions to mathematics. Ranging from topics in 'social arithmetic' such as demographics, utility theory, the twin scourges of hereditary advantage and slavery, daylight savings time, and even war and peace to puzzles, combinatorics, and magic squares, his work, as revealed in Paul Pasles's wonderful new book, reveals another facet of this polymathic statesman." "Paul C. Pasles is the first excellent mathematician to appreciate and to explain clearly the many aspects of what he has called Franklin's 'miraculous numerical creations.' In the capstone, Pasles explains how and why Franklin's 'ultra-magical square' is a mathematical masterpiece." "Pasles has written a wonderful book demonstrating that Benjamin Franklin, in addition to all of his other talents, had a 'mathematical' mind. The book fills in the gaps left by Franklin's other biographers by giving us, for the first time, the details of his mathematical work, in particular his work on magic squares." "Paul Pasles tells an entertaining and rigorous story, weaving together a familiar biography with new research on Franklin's innovative work on magic squares. Marching together, Ben Franklin and Paul Pasles may yet be able to rescue that vanishing viewpoint that finds both purpose and playfulness in public life and mathematics." "It takes someone with a mathematician's background to be able to analyze the true talent that Franklin exhibited in the field, and until now none of his biographers has had the requisite knowledge. Pasles's portrayal of both the human side and logical self of Benjamin Franklin is captivating."
