Overview
Few American lives have been as celebrated—or as closely scrutinized—as that of Benjamin Franklin. Yet until now Franklin's biographers have downplayed his interest in mathematics, at best portraying it as the idle musings of a brilliant and ever-restless mind. In Benjamin Franklin's Numbers, Paul Pasles reveals a side of the iconic statesman, scientist, and writer that few Americans know—his mathematical side.
In fact, Franklin indulged in many areas of mathematics, including number theory, geometry, statistics, and economics. In this generously illustrated book, Pasles gives us the first mathematical biography of Benjamin Franklin. He draws upon previously unknown sources to illustrate Franklin's genius for numbers as never before. Magic squares and circles were a lifelong fascination of Franklin's. Here, for the first time, Pasles gathers every one of these marvelous creations together in one place. He explains the mathematics behind them and Franklin's hugely popular Poor Richard's Almanac, which featured such things as population estimates and a host of mathematical digressions. Pasles even includes optional math problems that challenge readers to match wits with the bespectacled Founding Father himself. Written for a general audience, this book assumes no technical skills beyond basic arithmetic.
Benjamin Franklin's Numbers is a delightful blend of biography, history, and popular mathematics. If you think you already know Franklin's story, this entertaining and richly detailed book will make you think again.
Synopsis
"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."--Underwood Dudley, author of Numerology
"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."--John Allen Paulos, author of Innumeracy
"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."--J. A. Leo Lemay, University of Delaware
"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."--Victor J. Katz, author of A History of Mathematics
"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."--Woollcott Smith, coauthor of The Cartoon Guide to Statistics
"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."--David E. Zitarelli, Temple University
Publishers Weekly
Pasles, an associate professor of mathematics at Villanova, speculates gleefully on the oft-denied mathematical genius of Benjamin Franklin. The author focuses on magic squares, a type of matrix that Franklin dismissed (inaccurately) as "incapable of any useful application" but enjoyed playing with for almost 50 years. Not content with matrices where columns, rows and diagonals all have equal sums, Franklin created magic squares where bent diagonals and other groupings have special properties and then went on to develop even more complex magic circles, outclassing not only his contemporaries but also many modern mathematicians Drawing on Franklin's letters and journals as well as modern-day reconstructions of his library, Pasles touches on Franklin's fondness for magazines of mathematical diversions; publication of arithmetic problems in Poor Richard's Almanac; startlingly accurate projections of population growth and cost-benefit arguments against slavery. Going further afield, he suggests that only a man comfortable with numbers would refer to electrical poles as "positive" and "negative" and wonders what might have transpired had a young Franklin been introduced to Isaac Newton by a mutual acquaintance. Historians may quail at the textbook-style problems that illustrate various topics, but mathematicians will enjoy them and share Pasles's pleasure at restoring Franklin's tarnished numerological reputation.

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.Mathematical Reviews -

There is hardly a discipline on which Franklin did not stamp his mark during the 18th century. But the role that mathematics played in his life has been overlooked, argues Paul Pasles. Franklin, for instance, was fascinated with magic squares, and this book provides plenty of background to help the reader admire his interest.Civil Engineering
