From the Publisher
“If you ever lie awake pondering the complexities of the universe, you may have a soul buddy in Brian Hayes.” New Scientist
“Hayes is an assured and genial guide through the often thorny wilds of computation and mathematics.” The Star-Tribune (Minneapolis–St. Paul)
“Group Theory in the Bedroom and Other Mathematical Diversions is a marvelous collection of thought-provoking essays that both inform and entertain. You'll be amazed by the things you'll discover in these stories.” Ron Graham, professor of mathematics, computer science and engineering, University of California, San Diego, former chief scientist of AT&T, and past president of the American Mathematical Society, the Mathematical Association of America and the International Jugglers Association
“Brian Hayes's book is a refreshing collection of superb mathematical essays. Ranging from choosing up sides to choosing names, the topics are intriguingly nonstandard. Moreover, the writing is clean, the explanations are pellucid, and the effect on the reader is exhilarating. First-rate all the way through.” John Allen Paulos, author of Innumeracy: Mathematical Illiteracy and Its Consequences and the forthcoming Irreligion: A Mathematician Explains Why the Arguments for God Just Don't Add Up
“Every essay in this book is a gem of science writing on its highest level--accurate, up to date, brimming with surprising information, deep insights, and a profound love of mathematics. Its scope is awesome. Topics include a fantastic clock in Strasbourg, randomness, poverty, war, geology, genetics, gear ratios, partitions, nomenclature, group theory, and the ambiguity of the equals sign. There isn't a dull page in the book.” Martin Gardner, author of The Colossal Book of Short Puzzles and Problems and more than 60 other titles

In charming prose that more or less makes up for the relative lack of rigor in many of his explorations, about which Hayes is refreshingly honest ("I see no reason to doubt this assumption, at least as an approximation, but I also have no evidence to support it"), science and technology journalist Hayes (Infrastructure) explains the engineering and arithmetic of clocks and gears, wracks his brain over questions of how best to flip a mattress and visits "the prettiest wrong idea in all of twentieth-century science... the vision of piglets suckling on messenger RNA." As he examines huge calculating tables rendered obsolete by computers, Hayes "cannot help wondering which of my labors will appear equally quaint and pathetic to some future reader." This observation is echoed by the afterwords where Hayes addresses pointed questions and observations from readers, displaying a brave willingness to admit error and acknowledge advances made since these pieces were first published in the Sciencesand American Scientist. Present-day readers would do best to approach this collection more for its literary merits than its revelation of obscure history or cutting-edge mathematical theory. 41 b&w illus.

If your idea of fun includes puzzling over the creation of an algorithm for the Continental Divide, then this essay collection by the former editor in chief of American Scientist(AS) will tickle your imagination. Hayes, now an award-winning columnist for AS, has put together some of his best pieces and has included with each a section called "Afterthoughts," in which he enthusiastically adds new information and humbly corrects old mistakes. Hayes explores topics as diverse as the centuries-old Strasbourg clock, economic theory, randomness, DNA, gear ratios, weather forecasting, and war and international relations. And with tongue firmly in cheek, he even writes about the ways that one can flip a mattress. Although one need not be a rocket scientist-or even an undergraduate math major-to understand Hayes's work, the wit and elegance of the essays are best appreciated by those with a solid math background and an interest in math play. Recommended for large public libraries and academic libraries supporting programs in mathematics and computer science.

A selection of "Computing Science" columns by American Scientist magazine's former editor-in-chief aimed at the numerate-or at least mathematically curious-reader. While you don't have to be a geek to appreciate Hayes's lively, self-effacing style (complete with afterthoughts), it helps to understand that computer science relies on a field of math called numerical analysis and uses algorithms-rules for generating solutions to problems through an iterative process (the way you learned to do square roots in high school). The first essay explains how clockmakers developed the gears and linkages that enabled fabled medieval clocks to reach remarkable accuracy, as well as predict the day Easter would fall on. Other essays celebrate the notion of random numbers and why they are so hard to achieve. Numerical analysis also plays a role in economic models based on the kinetic theory of gases or simplified markets involving iterations of buying and selling. Hayes goes on to explain how statistics have been applied to compute which quarrels-from interpersonal to world wars-are the deadliest (surprising results here). Also, he looks at how algorithms have been developed to determine ways to divide a random series of numbers into two parts with equal sums, or nearly equal sums if the series total is odd. Gears appear again in the form of algorithms, which yield practical tables of numbers to enable engineers to make gear trains to approximate complex ratios. A couple of essays probe areas only professionals might ponder, such as computing the location of the Continental Divide or why base 3 arithmetic is better than base 10 or binary systems. But the piece de resistance is the title essay, whichexplains why there is no algorithm whose repetitions would cycle through all four possible mattress positions that would assure equal wear and tear over time. Challenging but rewarding for anyone intrigued by numbers.
