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.

BECOMING

The former first lady opens up about her early life, her journey to the White House, and the eight history-making years that followed.

It’s not surprising that Obama grew up a rambunctious kid with a stubborn streak and an “I’ll show you” attitude. After all, it takes a special kind of moxie to survive being the first African-American FLOTUS—and not only survive, but thrive. For eight years, we witnessed the adversity the first family had to face, and now we get to read what it was really like growing up in a working-class family on Chicago’s South Side and ending up at the world’s most famous address. As the author amply shows, her can-do attitude was daunted at times by racism, leaving her wondering if she was good enough. Nevertheless, she persisted, graduating from Chicago’s first magnet high school, Princeton, and Harvard Law School, and pursuing careers in law and the nonprofit world. With her characteristic candor and dry wit, she recounts the story of her fateful meeting with her future husband. Once they were officially a couple, her feelings for him turned into a “toppling blast of lust, gratitude, fulfillment, wonder.” But for someone with a “natural resistance to chaos,” being the wife of an ambitious politician was no small feat, and becoming a mother along the way added another layer of complexity. Throw a presidential campaign into the mix, and even the most assured woman could begin to crack under the pressure. Later, adjusting to life in the White House was a formidable challenge for the self-described “control freak”—not to mention the difficulty of sparing their daughters the ugly side of politics and preserving their privacy as much as possible. Through it all, Obama remained determined to serve with grace and help others through initiatives like the White House garden and her campaign to fight childhood obesity. And even though she deems herself “not a political person,” she shares frank thoughts about the 2016 election.

An engrossing memoir as well as a lively treatise on what extraordinary grace under extraordinary pressure looks like.

NIGHT

Elie Wiesel spent his early years in a small Transylvanian town as one of four children. 

He was the only one of the family to survive what Francois Maurois, in his introduction, calls the "human holocaust" of the persecution of the Jews, which began with the restrictions, the singularization of the yellow star, the enclosure within the ghetto, and went on to the mass deportations to the ovens of Auschwitz and Buchenwald. There are unforgettable and horrifying scenes here in this spare and sombre memoir of this experience of the hanging of a child, of his first farewell with his father who leaves him an inheritance of a knife and a spoon, and of his last goodbye at Buchenwald his father's corpse is already cold let alone the long months of survival under unconscionable conditions. 

The author's youthfulness helps to assure the inevitable comparison with the Anne Frank diary although over and above the sphere of suffering shared, and in this case extended to the death march itself, there is no spiritual or emotional legacy here to offset any reader reluctance.
