Book Description
“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

Book Description
In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€"modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€"and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book.

Book Description
Only one person believed Jane Parnell when she reported being raped at twenty-one: the mountain man who first led her up one peak after another in the Colorado Rockies and who then became her husband. Parnell took to mountaineering in the Rocky Mountains as a means to overcome her family’s history of mental illness and the trauma of the rape. By age thirty she became the first woman to climb the 100 highest peaks of the state. But regaining her footing could not save her by-now-failing marriage. Unprepared emotionally and financially for singlehood, she kept climbing—the 200 highest peaks, then nearly all of the 300 highest. The mountains were the one anchor in her life that held. Finding few contemporary role models to validate her ambition, Parnell looked to the past for inspiration—to English travel writer Isabella Bird, who also sought refuge and transformation in the Colorado Rockies, notably by climbing Longs Peak in 1873 with the notorious mountain man Rocky Mountain Jim. Reading Bird’s now-classic A Lady’s Life in the Rocky Mountains emboldened Parnell to keep moving forward. She was not alone in her drive for independence. Parnell’s memoir spans half a century. Her personal journey dramatizes evolving gender roles from the 1950s to the present. As a child, she witnessed the first ascent of the Diamond on Longs Peak, the “Holy Grail” of alpine climbing in the Rockies. In 2002, she saw firsthand the catastrophic Colorado wildfires of climate change, and five years later, she nearly lost her leg in a climbing accident. In the tradition of Cheryl Strayed’s Wild and Tracy Ross’s The Source of All Things, Parnell’s mountaineering memoir shows us how, by pushing ourselves to the limits of our physical endurance and by confronting our deepest fears, we can become whole again.

Book Description
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.”
