Do you find it difficult to remember how to solve a differential equation? Do probabilities and statistics drive you up the wall? Is your six year-old’s math homework giving you fits? If so, you may enjoy The Joy of X: a Guided Tour of Math, From One to Infinity by Steven Strogatz, a sophisticated and lighthearted refresher of some of the most basic and some of the most cutting edge mathematical concepts to ever grace our minds (or our bookshelf).
Strogatz starts with the easy stuff—addition, subtraction, the number line—and progressively moves on to more abstract and advanced subjects, like calculus, group theory, and analytics. Using diagrams, literary allusions, and Sesame Street, Strogatz draws you into each topic and before you know it the rather short chapter is over. Presto! You’ve learned something. While this is by no means a comprehensive picture of mathematics, Strogatz simultaneously enlightens and entertains with each successively more challenging chapter. Like a magician willing to share a few choice trade secrets, Strogatz invites us to peek behind the curtain and uncover the mysteries of long forgotten concepts, such as quadratic equations, infinity, and the elusive prime numbers.
The chapters, many of which have been adapted from Strogatz’s New York Times column "The Elements of Math", are brief, accessible, and threaded with his enthusiasm for the topic at hand. This is a fascinating, quick, and approachable read for anyone who would like a math reboot, including parents, the curious, and those interested in discovering what sine waves have to do with Romeo and Juliet’s love life.
