WHILE Paul Nahin is not the first to proclaim the power and beauty of mathematics, few have alluded to the 鈥渆rotic connection between mathematical insight and sexual orgasm鈥�. A stretch too far, perhaps, but Nahin鈥檚 tale of the formula e^{i 蟺} + 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. But be warned: it contains thousands of equations and is a challenging read.
