"In this intriguing study, maths historian Eli Maor traces those echoes, along with the trajectories of the scientists, inventors, composers, and occasional eccentrics behind them."---Barbara Kiser, Nature "The prolific author Eli Maor has released yet another very readable and enjoyable book on the history of mathematics from Princeton University Press. . . . As with all of Maors books, this one belongs in your library so that leading students can learn about unknowns like Joseph Sauveur in the fascinating story of how mathematics and music intersect."---Karl-Dieter Crisman, MAA Reviews "Maor is an experienced storyteller. His mixture of musical, mathematical, and physical history, enriched with personal experiences and some unexpected links and bridges are nice reading for anybody with a slight interest in music and science. No mathematical training required."---Adhemar Bultheel, European Mathematical Society "This is a fascinating study of the reciprocal relationship between music and mathematics in the West."---David Lorimer, Paradigm Explorer "For anyone who ponders the role mathematics has in music, this short and delightful book is a joy to read from cover to cover. It is full of anecdotes and interesting facts and, being by Eli Maor is intensely readable."---Phil Dyke, Leonardo Reviews "[ Music by the Numbers] is enjoyable and readable"---Owen Toller, Mathematical Gazette
