In the tradition of "Longitude, " a small and engagingly written book on the history and meaning of zero--a "tour de force" of science history that takes us through the hollow circle that leads to infinity. 32 illustrations.
A NEW YORK TIMES NOTABLE BOOK The Babylonians invented it, the Greeks banned it, the Hindus worshipped it, and the Christian Church used it to fend off heretics. Today it's a timebomb ticking in the heart of astrophysics. For zero, infinity's twin, is not like other numbers. It is both nothing and everything. Zero has pitted East against West and faith against reason, and its intransigence persists in the dark core of a black hole and the brilliant flash of the Big Bang. Today, zero lies at the heart of one of the biggest scientific controversies of all time: the quest for a theory of everything. Within the concept of zero lies a philosophical and scientific history of humanity. Charles Seife's elegant and witty account takes us from Aristotle to superstring theory by way of Egyptian geometry, Kabbalism, Einstein, the Chandrasekhar limit and Stephen Hawking. Covering centuries of thought, it is a concise tour of a world of ideas, bound up in the simple notion of nothing.
“A captivating story, not just an intellectual quest but a personal one . . . gripping [and] filled with the passion and wonder of numbers.” —The New York Times Virtually everything in our lives is digital, numerical, or quantified. But the story of how and where we got these numerals, which we so depend on, has for thousands of years been shrouded in mystery. Finding Zero is the saga of Amir Aczel’s lifelong obsession: to find the original sources of our numerals, perhaps the greatest abstraction the human mind has ever created. Aczel has doggedly crisscrossed the ancient world, scouring dusty, moldy texts, cross-examining so-called scholars who offered wildly differing sets of facts, and ultimately penetrating deep into a Cambodian jungle to find a definitive proof. Here, he takes the reader along for the ride. The history begins with Babylonian cuneiform numbers, followed by Greek and Roman letter numerals. Then Aczel asks: Where do the numbers we use today, the so-called Hindu-Arabic numerals, come from? It is this search that leads him to explore uncharted territory on a grand quest into India, Thailand, Laos, Vietnam, and ultimately into the wilds of Cambodia. There he is blown away to find the earliest zero—the keystone of our entire system of numbers—on a crumbling, vine-covered wall of a seventh-century temple adorned with eaten-away erotic sculptures. While on this odyssey, Aczel meets a host of fascinating characters: academics in search of truth, jungle trekkers looking for adventure, surprisingly honest politicians, shameless smugglers, and treacherous archaeological thieves—who finally reveal where our numbers come from. “A historical adventure that doubles as a surprisingly engaging math lesson . . . rip-roaring exploits and escapades.” —Publishers Weekly
Hollis Henry never intended to work for global marketing magnate Hubertus Bigend again. But now she’s broke, and Bigend has just the thing to get her back in the game... Milgrim can disappear in almost any setting, and his Russian is perfectly idiomatic—so much so that he spoke it with his therapist in the secret Swiss clinic where Bigend paid for him to be cured of his addiction... Garreth doesn't owe Bigend a thing. But he does have friends from whom he can call in the kinds of favors powerful people need when things go sideways... They all have something Bigend wants as he finds himself outmaneuvered and adrift, after a Department of Defense contract for combat-wear turns out to be the gateway drug for arms dealers so shadowy they can out-Bigend Bigend himself. “Zero History is [Gibson’s] best yet, a triumph of science fiction as social criticism and adventure.”—BoingBoing.net
"Traces the development of numerical systems in Sumerian, Egyptian, Greek, Roman, Chinese, Babylonian, and Mayan cultures, and examines the origins of the Hindu-Arabic numerals we use today"--Back cover.
In late summer 1929, a countrywide outbreak of Arab-Jewish-British violence transformed the political landscape of Palestine forever. In contrast with those who point to the wars of 1948 and 1967, historian Hillel Cohen marks these bloody events as year zero of the Arab-Israeli conflict that persists today. The murderous violence inflicted on Jews caused a fractious - and now traumatized - community of Zionists, non-Zionists, Ashkenazim, and Mizrachim to coalesce around a unified national consciousness arrayed against an implacable Arab enemy. While the Jews unified, Arabs came to grasp the national essence of the conflict, realizing that Jews of all stripes viewed the land as belonging to the Jewish people. Through memory and historiography, in a manner both associative and highly calculated, Cohen traces the horrific events of August 23 to September 1 in painstaking detail. He extends his geographic and chronological reach and uses a non-linear reconstruction of events to call for a thorough reconsideration of cause and effect. Sifting through Arab and Hebrew sources - many rarely, if ever, examined before - Cohen reflects on the attitudes and perceptions of Jews and Arabs who experienced the events and, most significantly, on the memories they bequeathed to later generations. The result is a multifaceted and revealing examination of a formative series of episodes that will intrigue historians, political scientists, and others interested in understanding the essence - and the very beginning - of what has been an intractable conflict.
A famed political scientist's classic argument for a more cooperative world We assume that, in a world ruled by natural selection, selfishness pays. So why cooperate? In The Evolution of Cooperation, political scientist Robert Axelrod seeks to answer this question. In 1980, he organized the famed Computer Prisoners Dilemma Tournament, which sought to find the optimal strategy for survival in a particular game. Over and over, the simplest strategy, a cooperative program called Tit for Tat, shut out the competition. In other words, cooperation, not unfettered competition, turns out to be our best chance for survival. A vital book for leaders and decision makers, The Evolution of Cooperation reveals how cooperative principles help us think better about everything from military strategy, to political elections, to family dynamics.
NEW YORK TIMES BESTSELLER • “This is one of those books that will go down as the seminal work—the determinative work—in this field. . . . Terrifying.”—Rachel Maddow The first definitive account of the rise and fall of the Secret Service, from the Kennedy assassination to the alarming mismanagement of the Obama and Trump years, right up to the insurrection at the Capitol on January 6—by the Pulitzer Prize winner and #1 New York Times bestselling co-author of A Very Stable Genius and I Alone Can Fix It NAMED ONE OF THE BEST BOOKS OF THE YEAR BY THE WASHINGTON POST Carol Leonnig has been reporting on the Secret Service for The Washington Post for most of the last decade, bringing to light the secrets, scandals, and shortcomings that plague the agency today—from a toxic work culture to dangerously outdated equipment to the deep resentment within the ranks at key agency leaders, who put protecting the agency’s once-hallowed image before fixing its flaws. But the Secret Service wasn’t always so troubled. The Secret Service was born in 1865, in the wake of the assassination of Abraham Lincoln, but its story begins in earnest in 1963, with the death of John F. Kennedy. Shocked into reform by its failure to protect the president on that fateful day in Dallas, this once-sleepy agency was radically transformed into an elite, highly trained unit that would redeem itself several times, most famously in 1981 by thwarting an assassination attempt against Ronald Reagan. But this reputation for courage and excellence would not last forever. By Barack Obama’s presidency, the once-proud Secret Service was running on fumes and beset by mistakes and alarming lapses in judgment: break-ins at the White House, an armed gunman firing into the windows of the residence while confused agents stood by, and a massive prostitution scandal among agents in Cartagena, to name just a few. With Donald Trump’s arrival, a series of promised reforms were cast aside, as a president disdainful of public service instead abused the Secret Service to rack up political and personal gains. To explore these problems in the ranks, Leonnig interviewed dozens of current and former agents, government officials, and whistleblowers who put their jobs on the line to speak out about a hobbled agency that’s in desperate need of reform. “I will be forever grateful to them for risking their careers,” she writes, “not because they wanted to share tantalizing gossip about presidents and their families, but because they know that the Service is broken and needs fixing. By telling their story, they hope to revive the Service they love.”
This is a graduate text introducing the fundamentals of measure theory and integration theory, which is the foundation of modern real analysis. The text focuses first on the concrete setting of Lebesgue measure and the Lebesgue integral (which in turn is motivated by the more classical concepts of Jordan measure and the Riemann integral), before moving on to abstract measure and integration theory, including the standard convergence theorems, Fubini's theorem, and the Carathéodory extension theorem. Classical differentiation theorems, such as the Lebesgue and Rademacher differentiation theorems, are also covered, as are connections with probability theory. The material is intended to cover a quarter or semester's worth of material for a first graduate course in real analysis. There is an emphasis in the text on tying together the abstract and the concrete sides of the subject, using the latter to illustrate and motivate the former. The central role of key principles (such as Littlewood's three principles) as providing guiding intuition to the subject is also emphasized. There are a large number of exercises throughout that develop key aspects of the theory, and are thus an integral component of the text. As a supplementary section, a discussion of general problem-solving strategies in analysis is also given. The last three sections discuss optional topics related to the main matter of the book.
