Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    You have to keep things close to your chest and be aware of what’s really important: the work, not everything around it. If you have faith in the work, then the people will come … it’s an artistic imperative, it has nothing to do with public perception or career or any of that crap. "The name, Swans, it’s synonymous with who I am, but it’s how it’s achieved and it’s achieved by people—those people need to have total commitment to making this sound and to making it utterly incisive and uncompromising. The work is everything and it has to—at least at the time—appear, to me, to be stellar. That’s the prerequisite. It’s an intangible thing where it really speaks and has some truth within it."—Michael Gira Over a span of some three and a half decades, Michael Gira’s Swans have risen from chaotic origins in the aftermath of New York’s No Wave scene to become one of the most acclaimed rock-orientated acts of recent years. The 1980s’ infamous ‘loudest band on the planet’ morphed repeatedly until collapsing exhausted, broken, and dispirited in the late 1990s. Swans returned triumphantly in 2010 to top end-of-year polls and achieve feted status among fans and critics alike as the great survivors and latter-day statesmen of the underground scene. Throughout, Gira’s desire has remained to create music of such intensity that the listener might forget flesh, get rid of the body, exist as pure energy—transcendent—inside of the sound. Through these pages, the musicians responsible tell the tale of one of the most significant bands of the US post-punk era. Drawing on more than 125 original interviews, Swans: Sacrifice And Transcendence is the ultimate companion to Swans and their work from the 1980s to the present day.

    In this unconventional introduction, physicist Leonard Susskind and hacker-scientist George Hrabovsky offer a first course in physics and associated math for the ardent amateur. Unlike most popular physics books—which give readers a taste of what physicists know but shy away from equations or math—Susskind and Hrabovsky actually teach the skills you need to do physics, beginning with classical mechanics, yourself. Based on Susskind's enormously popular Stanford University-based (and YouTube-featured) continuing-education course, the authors cover the minimum—the theoretical minimum of the title—that readers need to master to study more advanced topics.An alternative to the conventional go-to-college method, The Theoretical Minimum provides a tool kit for amateur scientists to learn physics at their own pace.

    A biography of the first family of radioactivity, focuses on their ground-breaking contributions to science, including the discovery of radium.

    Called a madman by his enemies, a genius by others, and an enigma by nearly everyone, Nikola Tesla was, without a doubt, a trailblazing inventor who created astonishing, sometimes world-transforming devices that were virtually without theoretical precedent. Tesla not only discovered the rotating magnetic field -- the basis of most alternating-current machinery -- but also introduced us to the fundamentals of robotics, computers, and missile science. Almost supernaturally gifted, unfailingly flamboyant and neurotic, Tesla was troubled by an array of compulsions and phobias and was fond of extravagant, visionary experimentations. He was also a popular man-about-town, admired by men as diverse as Mark Twain and George Westinghouse, and adored by scores of society beauties. From Tesla's childhood in Yugoslavia to his death in New York in the 1940s, Cheney paints a compelling human portrait and chronicles a lifetime of discoveries that radically altered -- and continue to alter -- the world in which we live. Tesla: Man Out of Time is an in-depth look at the seminal accomplishments of a scientific wizard and a thoughtful examination of the obsessions and eccentricities of the man behind the science.

    But it would take the world some time to believe what had happened: the age of flight had begun, with the first heavier-than-air, powered machine carrying a pilot.Who were these men and how was it that they achieved what they did?David McCullough, two-time winner of the Pulitzer Prize, tells the surprising, profoundly American story of Wilbur and Orville Wright.Far more than a couple of unschooled Dayton bicycle mechanics who happened to hit on success, they were men of exceptional courage and determination, and of far-ranging intellectual interests and ceaseless curiosity, much of which they attributed to their upbringing. The house they lived in had no electricity or indoor plumbing, but there were books aplenty, supplied mainly by their preacher father, and they never stopped reading.When they worked together, no problem seemed to be insurmountable. Wilbur was unquestionably a genius. Orville had such mechanical ingenuity as few had ever seen. That they had no more than a public high school education, little money and no contacts in high places, never stopped them in their mission to take to the air. Nothing did, not even the self-evident reality that every time they took off in one of their contrivances, they risked being killed.In this thrilling book, master historian David McCullough draws on the immense riches of the Wright Papers, including private diaries, notebooks, scrapbooks, and more than a thousand letters from private family correspondence to tell the human side of the Wright Brothers' story, including the little-known contributions of their sister, Katharine, without whom things might well have gone differently for them.

    Mass starvation, long predicted for the fast-growing population, was about to become a reality. A call went out to the world’s scientists to find a solution. This is the story of the two enormously gifted, fatally flawed men who found it: the brilliant, self-important Fritz Haber and the reclusive, alcoholic Carl Bosch. Together they discovered a way to make bread out of air, built city-sized factories, controlled world markets, and saved millions of lives. Their invention continues to feed us today; without it, more than two billion people would starve.But their epochal triumph came at a price we are still paying. The Haber-Bosch process was also used to make the gunpowder and high explosives that killed millions during the two world wars. Both men were vilified during their lives; both, disillusioned and disgraced, died tragically. Today we face the other un­intended consequences of their discovery—massive nitrogen pollution and a growing pandemic of obesity.The Alchemy of Air is the extraordinary, previously untold story of two master scientists who saved the world only to lose everything and of the unforseen results of a discovery that continues to shape our lives in the most fundamental and dramatic of ways.

    This groundbreaking collection of documents, essays, articles, and excerpts from histories, biographies, plays, novels, letters, and the oral histories of key eyewitnesses provides unique perspectives for the historian and student of history all compiled by experts at the Atomic Heritage Foundation. Photographs throughout depict key moments and pivotal figures. The Manhattan Project gives actual voice to a significant period in history.

    “We were the best bloody band there was,” he says. “There was nobody to touch us.” Nobody except the original nowhere man, Mark David Chapman. Chapman once worshipped his idols from afar—but now harbors grudges against those, like Lennon, whom he feels betrayed him. He’s convinced Lennon has misled fans with his message of hope and peace. And Chapman’s not staying away any longer.  By the summer of 1980, Lennon is recording new music for the first time in years, energized and ready for it to be “(Just Like) Starting Over.” He can’t wait to show the world what he will do.  Neither can Chapman, who quits his security job and boards a flight to New York, a handgun and bullets stowed in his luggage.  The greatest true-crime story in music history, as only James Patterson can tell it. Enriched by exclusive interviews with Lennon’s friends and associates, including Paul McCartney, The Last Days of John Lennon is the thrilling true story of two men who changed history: One whose indelible songs enliven our world to this day—and the other who ended the beautiful music with five pulls of a trigger.

    Xinran made the trip and met the woman, called Shu Wen, who recounted the story of her thirty-year odyssey in the vast landscape of Tibet.Shu Wen and her husband had been married for only a few months in the 1950s when he joined the Chinese army and was sent to Tibet for the purpose of unification of the two countries. Shortly after he left she was notified that he had been killed, although no details were given. Determined to find the truth, Shu Wen joined a militia unit going to the Tibetan north, where she soon was separated from the regiment. Without supplies and knowledge of the language, she wandered, trying to find her way until, on the brink of death, she was rescued by a family of nomads under whose protection she moved from place to place with the seasons and eventually came to discover the details of her husband's death.In the haunting Sky Burial, Xinran has recreated Shu Wen's journey, writing beautifully and simply of the silence and the emptiness in which Shu Wen was enveloped. The book is an extraordinary portrait of a woman and a land, each at the mercy of fate and politics. It is an unforgettable, ultimately uplifting tale of love, loss, loyalty, and survival.

    During this time he has broken into a Space Station with a Swiss army knife, disposed of a live snake while piloting a plane, and been temporarily blinded while clinging to the exterior of an orbiting spacecraft. The secret to Col. Hadfield's success-and survival-is an unconventional philosophy he learned at NASA: prepare for the worst-and enjoy every moment of it. In An Astronaut's Guide to Life on Earth, Col. Hadfield takes readers deep into his years of training and space exploration to show how to make the impossible possible. Through eye-opening, entertaining stories filled with the adrenaline of launch, the mesmerizing wonder of spacewalks, and the measured, calm responses mandated by crises, he explains how conventional wisdom can get in the way of achievement-and happiness. His own extraordinary education in space has taught him some counterintuitive lessons: don't visualize success, do care what others think, and always sweat the small stuff. You might never be able to build a robot, pilot a spacecraft, make a music video or perform basic surgery in zero gravity like Col. Hadfield. But his vivid and refreshing insights will teach you how to think like an astronaut, and will change, completely, the way you view life on Earth-especially your own.

    Gawky, socially awkward and totally unqualified, his first reaction to this exciting opportunity was panic. But he'd always been drawn to off-beat characters, so maybe his enthusiasm would carry the day. Or, you know, maybe it wouldn't...In Gotta Get Theroux This, Louis takes the reader on a joyous journey through his life and unexpectedly successful career. Nervously accepting the BBC's offer of his own series, he went on to create an award-winning documentary style that has seen him immersed in worlds as diverse as racist US militias and secretive pro-wrestlers, the violent gangs of Johannesburg and extreme drinkers in London.Arguably his biggest challenge was corralling celebrities in his When Louis Met series, with Jimmy Savile proving most elusive. Blindsided when the revelations about Savile came to light, Louis was to reflect again on the nature of evil he had spent decades uncovering.Filled with wry observation, larger-than-life characters, and self-deprecating humour, this is Louis at his insightful and honest best.

    He argues that the only feasible explanations of scientific successes are historical explanations, and that anarchism must now replace rationalism in the theory of knowledge.

    Tears of the Desert is the first memoir ever written by a woman caught up in the war in Darfur. It is a survivor's tale of a conflicted country, a resilient people, and the uncompromising spirit of a young woman who refused to be silenced.Born into the Zaghawa tribe in the Sudanese desert, Halima was doted on by her father, a cattle herder, and kept in line by her formidable grandmother. A politically astute man, Halima's father saw to it that his daughter received a good education away from their rural surroundings. Halima excelled in her studies and exams, surpassing even the privileged Arab girls who looked down their noses at the black Africans. With her love of learning and her father's support, Halima went on to study medicine, and at twenty-four became her village's first formal doctor.Yet not even the symbol of good luck that dotted her eye could protect her from the encroaching conflict that would consume her land. Janjaweed Arab militias started savagely assaulting the Zaghawa, often with the backing of the Sudanese military. Then, in early 2004, the Janjaweed attacked Bashir's village and surrounding areas, raping forty-two schoolgirls and their teachers. Bashir, who treated the traumatized victims, some as young as eight years old, could no longer remain quiet. But breaking her silence ignited a horrifying turn of events.In this harrowing and heartbreaking account, Halima Bashir sheds light on the hundreds of thousands of innocent lives being eradicated by what is fast becoming one of the most terrifying genocides of the twenty-first century. Raw and riveting, Tears of the Desert is more than just a memoir--it is Halima Bashir's global call to action.

      In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.
