What a treasure of a book this is! This is the fourth enthusiastic, informative, and delightful book Paul Nahin has written about the beauties of various areas of mathematics. . . . This book is a marvelous tribute to Euler's genius and those who built upon it and would make a great present for students of mathematics, physics, and engineering and their professors.---Henry Ricardo, , MAA Reviews
It is very difficult to sum up the greatness of Euler. . . . This excellent book goes a long way to explaining the kind of mathematician he really was.---Steve Humble, Mathematics Today
"The range and variety of topics covered here is impressive. I found many little gems that I have never seen before in books of this type. Moreover, the writing is lively and enthusiastic and the book is highly readable."—Des Higham, University of Strathclyde, Glasgow
The heart and soul of the book are the final three chapters on Fourier series, Fourier integrals, and related engineering. One can recommend them to all applied math students for their historical development and sensible content.---Robert E. O'Malley, Jr., SIAM Review
"If you ever wondered about the beauties and powers of mathematics, this book is a treasure trove. Paul Nahin uses Euler's formula as the magic key to unlock a wealth of surprising consequences, ranging from number theory to electronics, presented clearly, carefully, and with verve."—Peter Pesic, St. John's College

Nahin's tale of the formula e[pi] i+1=0, which links five of the most important numbers in mathematics, is remarkable. With a plethora of historical and anecdotal material and a knack for linking events and facts, he gives the reader a strong sense of what drove mathematicians like Euler.---Matthew Killeya, , New Scientist
Nahin includes gems from all over mathematics, ranging from engineering applications to beautiful pure-mathematical identities. . . . It would be good to have more books like this.---Timothy Gowers, Nature
It is a 'popular' book, written for a general reader with some mathematical background equivalent to a first-year undergraduate course in the UK.---Robin Wilson, London Mathematical Society Newsletter
This is a book for mathematicians who enjoy historically motivated mathematical explanations on a high mathematical level.---Eberhard Knobloch, Mathematical Reviews
