But in this fascinating book, Annemarie Schimmel shows that numbers have been filled with mystery and meaning since the earliest times, and across every society.In The Mystery of Numbers Annemarie Schimmel conducts an illuminating tour of the mysteries attributed to numbers over the centuries. She begins with an informative and often surprising introduction to the origins of number systems: pre-Roman Europeans, for example, may have had one based on twenty, not ten (as suggested by the English word "score" and the French word for 80, quatrevingt—four times twenty), while the Mayans had a system more sophisticated than our own. Schimmel also reveals how our fascination with numbers has led to a rich cross-fertilization of mathematical knowledge: "Arabic" numerals, for instance, were picked up by Europe from the Arabs, who had earlier adopted them from Indian sources ("Algorithm" and "algebra" are corruptions of the Arabic author and title names of a mathematical text prized in medieval Europe). But the heart of the book is an engrossing guide to the symbolism of numbers. Number symbolism, she shows, has deep roots in Western culture, from the philosophy of the Pythagoreans and Platonists, to the religious mysticism of the Cabala and the Islamic Brethren of Purity, to Kepler's belief that the laws of planetary motion should be mathematically elegant, to the unlucky thirteen. After exploring the sources of number symbolism, Schimmel examines individual numbers ranging from one to ten thousand, discussing the meanings they have had for Judaic, Christian, and Islamic traditions, with examples from Indian, Chinese, and Native American cultures as well. Two, for instance, has widely been seen as a number of contradiction and polarity, a number of discord and antithesis. And six, according to ancient and neo-platonic thinking, is the most perfect number because it is both the sum and the product of its parts (1+2+3=6 and 1x2x3=6). Using examples ranging from the Bible to the Mayans to Shakespeare, she shows how numbers have been considered feminine and masculine, holy and evil, lucky and unlucky.A highly respected scholar of Islamic culture, Annemarie Schimmel draws on her vast knowledge to paint a rich, cross-cultural portrait of the many meanings of numbers. Engaging and accessible, her account uncovers the roots of a phenomenon we all feel every Friday the thirteenth.

    Precocious, self-conscious and preternaturally gifted, young Bruno, born and raised in a habitat at the local zoo, falls under the care of a university primatologist named Lydia Littlemore. Learning of Bruno's ability to speak, Lydia takes Bruno into her home to oversee his education and nurture his passion for painting. But for all of his gifts, the chimpanzee has a rough time caging his more primal urges. His untimely outbursts ultimately cost Lydia her job, and send the unlikely pair on the road in what proves to be one of the most unforgettable journeys -- and most affecting love stories -- in recent literature. Like its protagonist, this novel is big, loud, abrasive, witty, perverse, earnest and amazingly accomplished. The Evolution of Bruno Littlemore goes beyond satire by showing us not what it means, but what it feels like be human -- to love and lose, learn, aspire, grasp, and, in the end, to fail.

    From Stephen Levy—the author who made "hackers" a household word—comes this account of a revolution that is already affecting every citizen in the twenty-first century. Crypto tells the inside story of how a group of "crypto rebels"—nerds and visionaries turned freedom fighters—teamed up with corporate interests to beat Big Brother and ensure our privacy on the Internet. Levy's history of one of the most controversial and important topics of the digital age reads like the best futuristic fiction.

    Here is a volume of poetry approaching Carolyn Forche's The Angel of History as a stark meditation on Blanchot's sense of writing as the "desired, undesired torment which endures everything." Levine engages the traditional resources of lyric poetry in an exploration of historical and cultural landscapes ravaged by imponderable events. Enola Gay's "mission" can seem spiritual, imaginative, and militaristic as the speaker in these poems surveys marshes and fields and a land on the edge of disintegration. Levine sifts the psychological residue that accumulates in the wake of unspeakable acts and so negotiates that terrain between the banality of language and the need to stand witness and to speak. Levine's stunning second book, with its grave cultural implications and its surveillance of a distinctly postmodern malaise, offers multiple readings. Here are compact poems with uncanny power, rhythm, and a strange, formal beauty echoing and renewing the legacy of Wallace Stevens for a new era.

    In peace and war Taylor is as radiant as gold and as tough as diamond' Sam Kiley - author of Desperate Glory and Foreign Affairs Editor of Sky News. Chantelle Taylor joined the British Army in 1998 as a combat medical technician. Ten years later she made history, becoming the first female soldier to kill a Taliban fighter in close-quarter combat while on patrol in Helmand Province, Afghanistan. In Battleworn, she tells the story of B Company, a beleaguered group of individuals who fought relentlessly to hold Nad-e Ali, a dusty, sweltering hellhole surrounded by the Taliban. A routine patrol into an area saturated with enemy fighters escalates into a seven-week siege. Facing the possibility of death daily, Taylor writes of gun battles and perilous patrols, culminating in the extraction of more than sixty-six casualties with four killed in action. A powerful story written with a humility that captures the sometimes impalpable humour of soldiers at war, Battleworn provides a testament to combat medics all over the world. It highlights the crucial role that they play in today's 360-degree battlefield.

    

    But in March 1996, the robbery of a Hollywood Video store went horribly wrong, ending in a hail of gunfire and the worst mass murder in the history of Albuquerque, New Mexico. This book is based on the true story of three ex-cons who met through the New Mexico Community Corrections early release program. One was obsessed with movies and guns, another was hopelessly in love, and the third double-crossed them both. Initially, all hoped for a new and better life, but in this modern tragedy, the ex-cons' self-destructive impulses ultimately led to their doom and that of their innocent victims. An entire city was left to mourn.

    Michael, married to a double divorcee, Natasha, the daughter of a Moscow lawyer, was the first Romanov murdered by the Bolsheviks, five weeks before the other mass killings, and because he was the Romanov who posed the greatest threat to them. However, they never admitted responsibility for his murder, pretending instead that he had escaped. This book, based chiefly on original contemporary sources in Russia, tells you what the Soviet Union intended that you should never know. Does that matter now? Very much so, for unlike his brother Nicholas, Michael can serve as the bridge between today's Russia and Tsarist Russia, a gap which has yet to be closed. As Viktor Yevtukhov, appointed deputy Russian Minister of Justice in February 2011, has said: 'We should know more about this man and remember him, because this memory can give our society the ethical foundation we need'. This book will tell you why, after almost a century, that should be so. From the tragedy of the past, a hope for the future...

    Names like Bundy, Gacy, and Gein come to mind, alongside the many other murderous people out there who've gained notoriety because of their evil. When you're envisioning the unthinkable and heinous acts that are carried out in this world, it's unlikely you imagine a youngster as being a perpetrator of evil.Killer children, although rare, do exist. The thought alone is terrifying; we see children as being vulnerable and pure, which makes it harder to comprehend them wanting to inflict pain and suffering on another being. The correlation of a child and unthinkable acts of murder is undeniably tricky to compute.The children in this book carried out acts of savage murder - even just typing that sentence feels wrong. Some of these murders are sexually motivated; some are carried out for revenge; others are part of an occult ritual. Regardless of the motivation for these children to commit unspeakable acts of cruelty, they are all disturbing.This book was written to give you some food for thought, to allow you to digest some of the heinous crimes committed by youngsters and consider why they'd carry out such horrific acts. This book will open up a world of questions, many of which I've likely pondered upon myself. While I do offer up my own opinion throughout this book, I do need to (as much as possible) stick to the facts to let you make your own mind up.With that in mind, let's delve into some of the despicably horrific murders that were carried out by children.

    Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide.With a novelist's sensitivity, David Leavitt portrays Turing in all his humanity—his eccentricities, his brilliance, his fatal candor—and elegantly explains his work and its implications.
