HUMBLE PI

WHEN MATH GOES WRONG IN THE REAL WORLD

Fun reading for nonmathematicians.

A pleasant exploration of our deeply held incompetence at mathematics.

Comedian and YouTube performer Parker (Things To Make and Do in the Fourth Dimension: A Mathematician's Journey Through Narcissistic Numbers, Optimal Dating Algorithms, at Least Two Kinds of Infinity, and More, 2014), who hosts a show on the Science Channel called Outrageous Acts of Science, claims bluntly that humans are stupid at dealing with numbers. “We were not born with any kind of ability to understand fractions, negative numbers, or the many other strange concepts developed by mathematics,” he writes, “but, over time, your brain can slowly learn how to deal with them.” Ironically, it is engineering and computer glitches, not pure math, that make up much of the book. Buildings and bridges collapse because someone gets the numbers wrong. A squadron of advanced jets crossing the Pacific suddenly lost their electronics because their navigation computer program, which must keep track of time, couldn’t deal with crossing the International Date Line. They followed an older plane nearby to a safe landing. A corporation, searching for an employee named Jack Null, could never find him because “null” to a computer means “no data.” People named Blank, Sample, and Test also cause trouble. A number divided by a really tiny number becomes very large. The result of dividing by zero is meaningless; no proper computer will deal with it. Humans yearn to predict the unpredictable; the author shows how a truly random event (a lottery draw, a coin flip) has no influence on the following event. No matter how many times heads appears, the chance of tails remains 50-50. The only way to increase your chance of winning the lottery is to buy more tickets. If black comes up four, five, or 10 times in a row on the roulette wheel, gamblers rush to bet on red because it is “due”—but it isn’t. Nonsense, blunders, and delusions make for good reading, so Parker’s relentless litany will have a wide appeal.

Fun reading for nonmathematicians.

NUTCRACKER

This is not the Nutcracker sweet, as passed on by Tchaikovsky and Marius Petipa. No, this is the original Hoffmann tale of 1816, in which the froth of Christmas revelry occasionally parts to let the dark underside of childhood fantasies and fears peek through. The boundaries between dream and reality fade, just as Godfather Drosselmeier, the Nutcracker's creator, is seen as alternately sinister and jolly. And Italian artist Roberto Innocenti gives an errily realistic air to Marie's dreams, in richly detailed illustrations touched by a mysterious light. A beautiful version of this classic tale, which will captivate adults and children alike. (Nutcracker; $35.00; Oct. 28, 1996; 136 pp.; 0-15-100227-4)

TO THE ONE I LOVE THE BEST

EPISODES FROM THE LIFE OF LADY MENDL (ELSIE DE WOLFE)

An extravaganza in Bemelmans' inimitable vein, but written almost dead pan, with sly, amusing, sometimes biting undertones, breaking through. For Bemelmans was "the man who came to cocktails". And his hostess was Lady Mendl (Elsie de Wolfe), arbiter of American decorating taste over a generation. Lady Mendl was an incredible person,- self-made in proper American tradition on the one hand, for she had been haunted by the poverty of her childhood, and the years of struggle up from its ugliness,- until she became synonymous with the exotic, exquisite, worshipper at beauty's whrine. Bemelmans draws a portrait in extremes, through apt descriptions, through hilarious anecdote, through surprisingly sympathetic and understanding bits of appreciation. The scene shifts from Hollywood to the home she loved the best in Versailles. One meets in passing a vast roster of famous figures of the international and artistic set. And always one feels Bemelmans, slightly offstage, observing, recording, commenting, illustrated.
