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.Pub Date: July 5, 2011

Buffs of the Old West will enjoy Clavin’s careful research and vivid writing.
Rootin’-tootin’ history of the dry-gulchers, horn-swogglers, and outright killers who populated the Wild West’s wildest city in the late 19th century.
The stories of Wyatt Earp and company, the shootout at the O.K. Corral, and Geronimo and the Apache Wars are all well known. Clavin, who has written books on Dodge City and Wild Bill Hickok, delivers a solid narrative that usefully links significant events—making allies of white enemies, for instance, in facing down the Apache threat, rustling from Mexico, and other ethnically charged circumstances. The author is a touch revisionist, in the modern fashion, in noting that the Earps and Clantons weren’t as bloodthirsty as popular culture has made them out to be. For example, Wyatt and Bat Masterson “took the ‘peace’ in peace officer literally and knew that the way to tame the notorious town was not to outkill the bad guys but to intimidate them, sometimes with the help of a gun barrel to the skull.” Indeed, while some of the Clantons and some of the Earps died violently, most—Wyatt, Bat, Doc Holliday—died of cancer and other ailments, if only a few of old age. Clavin complicates the story by reminding readers that the Earps weren’t really the law in Tombstone and sometimes fell on the other side of the line and that the ordinary citizens of Tombstone and other famed Western venues valued order and peace and weren’t particularly keen on gunfighters and their mischief. Still, updating the old notion that the Earp myth is the American Iliad, the author is at his best when he delineates those fraught spasms of violence. “It is never a good sign for law-abiding citizens,” he writes at one high point, “to see Johnny Ringo rush into town, both him and his horse all in a lather.” Indeed not, even if Ringo wound up killing himself and law-abiding Tombstone faded into obscurity when the silver played out.
Buffs of the Old West will enjoy Clavin’s careful research and vivid writing.Pub Date: April 21, 2020

The latest from French writer/filmmaker Carrère (My Life as a Russian Novel, 2010, etc.) is an awkward but intermittently touching hybrid of novel and autobiography.
The book begins in Sri Lanka with the tsunami of 2004—a horror the author saw firsthand, and the aftermath of which he describes powerfully. Carrère and his partner, Hélène, then return to Paris—and do so with a mutual devotion that's been renewed and deepened by all they've witnessed. Back in France, Hélène's sister Juliette, a magistrate and mother of three small daughters, has suffered a recurrence of the cancer that crippled her in adolescence. After her death, Carrère decides to write an oblique tribute and an investigation into the ravages of grief. He focuses first on Juliette's colleague and intimate friend Étienne, himself an amputee and survivor of childhood cancer, and a man in whose talkativeness and strength Carrère sees parallels to himself ("He liked to talk about himself. It's my way, he said, of talking to and about others, and he remarked astutely that it was my way, too”). Étienne is a perceptive, dignified person and a loyal, loving friend, and Carrère's portrait of him—including an unexpectedly fascinating foray into Étienne and Juliette's chief professional accomplishment, which was to tap the new European courts for help in overturning longtime French precedents that advantaged credit-card companies over small borrowers—is impressive. Less successful is Carrère's account of Juliette's widower, Patrice, an unworldly cartoonist whom he admires for his fortitude but seems to consider something of a simpleton. Now and again, especially in the Étienne sections, Carrère's meditations pay off in fresh, pungent insights, and his account of Juliette's last days and of the aftermath (especially for her daughters) is quietly harrowing.Pub Date: Sept. 13, 2011
