"A Most Elegant Equation is a smart, incisive account of Euler's famous equation. It beautifully and seamlessly straddles the line between the salient ideas of the equation's proof and its historical, scientific, and philosophical significance."
--- John Allen Paulos, professor of mathematics at Temple University and author of Innumeracy and A Numerate Life
"Even though Pi, e, and i are Very Important Numbers, they seemed unrelated---until Euler discovered a simple, beautiful, and totally unexpected link between them. This delightful book shows us why the formula is surprising, yet inevitable. Thoroughly enjoyable!"
--- Ian Stewart, author of Significant Figures
"Does mathematics transcend our humanness, or is it simply a human construct? Either way, the astonishing interconnections and stunning beauty that mathematics offers can only serve to uplift our human souls. The poetry of 'e to the i pi,' as exemplified by David Stipp, masterfully proves this."
--- James Tanton, Mathematician-at-Large for the Mathematical Association of America
"As a non-professional recovering mathlete, I found A Most Elegant Equation a delightful excursion into the beauty of mathematical thinking. Not only is Stipp a great storyteller, he is a terrific teacher with an easy conversational style who makes the most complex concepts lucid. For anyone who was ever afraid of math, here's your cure."
