Foolproof, and Other Mathematical Meditations


Book Description

A non-mathematician explores mathematical terrain, reporting accessibly and engagingly on topics from Sudoku to probability. Brian Hayes wants to convince us that mathematics is too important and too much fun to be left to the mathematicians. Foolproof, and Other Mathematical Meditations is his entertaining and accessible exploration of mathematical terrain both far-flung and nearby, bringing readers tidings of mathematical topics from Markov chains to Sudoku. Hayes, a non-mathematician, argues that mathematics is not only an essential tool for understanding the world but also a world unto itself, filled with objects and patterns that transcend earthly reality. In a series of essays, Hayes sets off to explore this exotic terrain, and takes the reader with him. Math has a bad reputation: dull, difficult, detached from daily life. As a talking Barbie doll opined, “Math class is tough.” But Hayes makes math seem fun. Whether he's tracing the genealogy of a well-worn anecdote about a famous mathematical prodigy, or speculating about what would happen to a lost ball in the nth dimension, or explaining that there are such things as quasirandom numbers, Hayes wants readers to share his enthusiasm. That's why he imagines a cinematic treatment of the discovery of the Riemann zeta function (“The year: 1972. The scene: Afternoon tea in Fuld Hall at the Institute for Advanced Study in Princeton, New Jersey”), explains that there is math in Sudoku after all, and describes better-than-average averages. Even when some of these essays involve a hike up the learning curve, the view from the top is worth it.

The Helpline


Book Description

An eccentric woman who is great with numbers—but not so great with people—realizes it’s up to her to pull a community together in this charming, big-hearted debut perfect for fans of Eleanor Oliphant Is Completely Fine and The Rosie Project. Germaine Johnson doesn’t need friends. She has her work and her Sudoku puzzles. Until, that is, an incident at her insurance company leaves her jobless—and it turns out that there are very few openings these days for senior mathematicians with zero people skills. Soon enough though, Germaine manages to secure a position at City Hall answering calls on the Senior Citizens Helpline. But it turns out that the mayor has something else in mind for Germaine: a secret project involving the troublemakers at the senior citizens center and their feud with the neighboring golf club—which happens to be run by the dashing yet disgraced national Sudoku champion, Don Thomas, a celebrity of the highest order to Germaine. Don and the mayor want the senior center closed down and at first, Germaine is dedicated to helping them out—it makes sense mathematically, after all. But when Germaine actually gets to know the group of elderly rebels at the senior center, they open her eyes to a life outside of boxes and numbers and for the first time ever, Germaine realizes she may have miscalculated. Filled with an eccentric, totally unique, and (occasionally) cranky cast of characters you can’t help but love, The Helpline is a feel-good page-turner that will make you reexamine what it means to lead a happy life—and is bound to capture your heart along the way.
