THE MAN OF NUMBERS

FIBONACCI'S ARITHMETIC REVOLUTION

Three cheers for Leonardo Pisano, nicknamed Fibonacci, heralded by NPR’s “Math Guy” Devlin (Mathematics Education for a New Era: Video Games as a Medium for Learning, 2011, etc.) as the man who introduced Hindu-Arabic numbers (0 to 9) and rules of arithmetic to Europe in the 13th century.

The author writes that by far the most important contribution that Pisano native made to Western culture was not the Fibonacci numbers (the series in which each term is the sum of the two previous terms, e.g., 1,1,2,3,5,8,13—celebrated in The Da Vinci Code) but the replacement of Roman numerals with the familiar 10 digits and place notation. That was a boon to merchants and bankers, moneychangers and tax collectors, just when the world was poised for the science and technology discoveries of the Renaissance. It all came about because Pisano’s father, a customs official, took his teenage son with him to North Africa, where the boy learned about the numerical system that Arab traders had brought from India. Devlin makes clear that he was not a passive transmitter of new knowledge but a gifted thinker whose magisterial Liber Abaci (Book of Calculation), published in 1202, and later popularizations, as well as works in algebra and geometry, mark him as one of mathematics’ great minds. As for the series, Pisano wrote that it was known early on to Indian scholars, and he stated it as a problem to determine how many rabbits a fertile pair would produce in a year “when it is the nature of them in a single month to bear another pair. And in the second month those born to bear also.”

A wonderful book for history-of-science buffs that will also amuse math teachers, because the many problems and solutions included are simply medieval versions of the word problems that are the bane of many high-school students.

UNTAMED

More life reflections from the bestselling author on themes of societal captivity and the catharsis of personal freedom.

In her third book, Doyle (Love Warrior, 2016, etc.) begins with a life-changing event. “Four years ago,” she writes, “married to the father of my three children, I fell in love with a woman.” That woman, Abby Wambach, would become her wife. Emblematically arranged into three sections—“Caged,” “Keys,” “Freedom”—the narrative offers, among other elements, vignettes about the soulful author’s girlhood, when she was bulimic and felt like a zoo animal, a “caged girl made for wide-open skies.” She followed the path that seemed right and appropriate based on her Catholic upbringing and adolescent conditioning. After a downward spiral into “drinking, drugging, and purging,” Doyle found sobriety and the authentic self she’d been suppressing. Still, there was trouble: Straining an already troubled marriage was her husband’s infidelity, which eventually led to life-altering choices and the discovery of a love she’d never experienced before. Throughout the book, Doyle remains open and candid, whether she’s admitting to rigging a high school homecoming court election or denouncing the doting perfectionism of “cream cheese parenting,” which is about “giving your children the best of everything.” The author’s fears and concerns are often mirrored by real-world issues: gender roles and bias, white privilege, racism, and religion-fueled homophobia and hypocrisy. Some stories merely skim the surface of larger issues, but Doyle revisits them in later sections and digs deeper, using friends and familial references to personify their impact on her life, both past and present. Shorter pieces, some only a page in length, manage to effectively translate an emotional gut punch, as when Doyle’s therapist called her blooming extramarital lesbian love a “dangerous distraction.” Ultimately, the narrative is an in-depth look at a courageous woman eager to share the wealth of her experiences by embracing vulnerability and reclaiming her inner strength and resiliency.

Doyle offers another lucid, inspiring chronicle of female empowerment and the rewards of self-awareness and renewal.

If the authors are serious, this is a silly, distasteful book. If they are not, it’s a brilliant satire.

THE 48 LAWS OF POWER

The authors have created a sort of anti-Book of Virtues in this encyclopedic compendium of the ways and means of power.

Everyone wants power and everyone is in a constant duplicitous game to gain more power at the expense of others, according to Greene, a screenwriter and former editor at Esquire (Elffers, a book packager, designed the volume, with its attractive marginalia). We live today as courtiers once did in royal courts: we must appear civil while attempting to crush all those around us. This power game can be played well or poorly, and in these 48 laws culled from the history and wisdom of the world’s greatest power players are the rules that must be followed to win. These laws boil down to being as ruthless, selfish, manipulative, and deceitful as possible. Each law, however, gets its own chapter: “Conceal Your Intentions,” “Always Say Less Than Necessary,” “Pose as a Friend, Work as a Spy,” and so on. Each chapter is conveniently broken down into sections on what happened to those who transgressed or observed the particular law, the key elements in this law, and ways to defensively reverse this law when it’s used against you. Quotations in the margins amplify the lesson being taught. While compelling in the way an auto accident might be, the book is simply nonsense. Rules often contradict each other. We are told, for instance, to “be conspicuous at all cost,” then told to “behave like others.” More seriously, Greene never really defines “power,” and he merely asserts, rather than offers evidence for, the Hobbesian world of all against all in which he insists we live. The world may be like this at times, but often it isn’t. To ask why this is so would be a far more useful project.

If the authors are serious, this is a silly, distasteful book. If they are not, it’s a brilliant satire.
