Together, they explain virtually everything about the world we live in. But, almost a century after their advent, most people haven't the slightest clue what either is about. Did you know that there's so much empty space inside matter that the entire human race could be squeezed into the volume of a sugar cube? Or that you grow old more quickly on the top floor of a building than on the ground floor? And did you realise that 1 percent of the static on a TV tuned between stations is a relic of the Big Bang?

    Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space: a multiverse in which you have an infinite number of doppelgängers, each reading this sentence in a distant universe; a multiverse comprising a vast ocean of bubble universes, of which ours is but one; a multiverse that endlessly cycles through time, or one that might be hovering millimeters away yet remains invisible; another in which every possibility allowed by quantum physics is brought to life. Or, perhaps strangest of all, a multiverse made purely of math.Greene, one of our foremost physicists and science writers, takes us on a captivating exploration of these parallel worlds and reveals how much of reality’s true nature may be deeply hidden within them. And, with his unrivaled ability to make the most challenging of material accessible and entertaining, Greene tackles the core question: How can fundamental science progress if great swaths of reality lie beyond our reach?Sparked by Greene’s trademark wit and precision, The Hidden Reality is at once a far-reaching survey of cutting-edge physics and a remarkable journey to the very edge of reality—a journey grounded firmly in science and limited only by our imagination.

    The first chapter describes basic features of the program and shows how to use it in simple arithmetic operations with scalars.

    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?

    Thomas Young devised it in the early 1800s to show that light behaves like a wave, and in doing so opposed Isaac Newton. Nearly a century later, Albert Einstein showed that light comes in quanta, or particles, and the experiment became key to a fierce debate between Einstein and Niels Bohr over the nature of reality. Richard Feynman held that the double slit embodies the central mystery of the quantum world. Decade after decade, hypothesis after hypothesis, scientists have returned to this ingenious experiment to help them answer deeper and deeper questions about the fabric of the universe.How can a single particle behave both like a particle and a wave? Does a particle exist before we look at it, or does the very act of looking create reality? Are there hidden aspects to reality missing from the orthodox view of quantum physics? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? And if there's no such place, then does the universe split into two each time a particle goes through the double slit?With his extraordinarily gifted eloquence, Anil Ananthaswamy travels around the world and through history, down to the smallest scales of physical reality we have yet fathomed. Through Two Doors at Once is the most fantastic voyage you can take.

    KEY TOPICS For each new device or circuit, the authors describe the principle of the operation, give thorough examples, and then show its actual application. An excellent reference on modern digital systems.

    I must admit I'm not exactly the same girl you left-I'm twice as independent as I used to be and to top it off, I sometimes think I've become 'hard as nails'. . . . Also--more and more I've been living exactly as I want to . . . I do as I damn please."[These tough words from the wife of a soldier show that World War Ii changed much more than just international politics.]"From a fascinating collection of letters, filled with wonderfully distinctive human stories, Judy Barrett Litoff and David C. Smith have shpaed a rare and brilliant book that transports the reader back in time to an unforgettable era."--Doris Kearns Goodwin, author of The Fitzgeralds and the Kennedys and Lyndon Johnson and the American Dream."This is a wonderful volume, full of admirable women struggling in a difficult situation, doing their best for their families and their country. Ah, the memories it brings back! Highly recommended for those who lived through the war, and for those who want to understand it."--Stephen E. Ambrose, author of Eisenhower and D-Day, June 6, 1944"Offering a remarkable view into the lives of ordinary women during wartime, this book will enlighten and catch at the hearts of general readers and cause historians to reconsider how women experienced World War II."-Susan M. Hartmann, author of The Home Front and Beyond."From among 25,000 of an estimated six billion letters sent overseas during World War II, Litoff and Smith have culled and skillfully edited a sampling by 400 American women. These letters, starting with one to a seaman wounded at Pearl Harbor, are compelling documents of home-front life in varied ethnic, cultural, and financial milieus. Tragic, touching, and funny, the correspondence is full of prosaic news and gossip about jobs and neighbors, along with accounts of births and intimate allusions to love-making. The stress of separation was intensified for women whose loved ones were hospitalized, or imprisoned as either conscientious objectors or security risks. Some women wrote General MacArthur and others for news of missing men or to obtain details of their deaths. Many of these heartrending documents also express acceptance-and even pride-in the sacrifices required by war."--Publishers Weekly."Other scholars of WW II have published letters written home by servicemen, but this is the first collection sampling the letters written by sisters, sweethearts, wives, and mothers, saved by thousands of servicemen. Chapters are organized around themes that were important to these women: courtship, marriage, motherhood, work, sacrifices. . . . What women tell readers in these letters about their concerns and their wartime feelings will cause historians [readers?] to rethink what has been written about the homefront."--Choice."Despite the popular appeal of Rosie the Riveter, nine out of ten mothers with children under six were not in the labor force, which helps to account for the vast outpouring of mail from the home front to 'our boys' in the European and Pacific theaters. Some couples wrote every day for four years. This is the rich historic documentation that the authors have drawn upon to create a panoramic pastiche of indefatigable, energetic, patriotic female letter writers in the war years. . . . One is struck by the hard-headed practicality of many of the letters-stories of plucky, sometimes even grumpy, coping. There are letters of growing independence, with strong and at times explicit indication that the boyfriend or husband will be facing a very different woman upon his return from the one he 'knew' when he disembarked for his own, often terrible, venture. . . . Every war leaves mothers with broken hearts. What this volume most remarkably demonstrates is just how prepared American women on the home front were for that dread eventuality."--Jean Bethke Elshtain in the Journal of American History."Fascinating and often heartbreaking letters. . . . The letters illuminate a time when sex roles were first showing the changes that would culminate in the women's movement. 'I must admit I'm not exactly the same girl you left, ' Edith Speert wrote to her husband, Victor, in 1945. 'I'm twice as independent as I used t be, and I sometimes think I've become hard as nails. I don't think my changes will affect our relationship.'. . . In the end, it is the small human dramas in these letters that stand out. Anne Gudis, miffed to distraction by her soldier-swain Sam Kramer, writes what may be the shortest Dear John on record: 'Mr. Kramer: Go to hell! With love, Anne Gudis.' A woman working at a Honolulu nightclub assures a pilot that she'll wait for him-until she's 20. The wife of an Air Corps navigator reads in a news story that only 15 of 1,500 Allied bombers were lost in a raid over Europe and later learns that her husband died in one of the 15. And a grieving mother whose son died in the Pacific asks Gen. Douglas MacArthur, in desperation, 'Please general he was a good boy, wasn't he? Did he die a hard death?'"--Smithsonian."'They made it possible for me to retain my sanity in an insane world, ' wrote one pilot about the letters his wife sent him throughout World War II. The letters contained in this collection explain the soldier's sentiments. Whether full of passionate longing for a missing sweetheart or merely detailing domestic gossip, the letters offer a rich introduction to how American women experienced the war. Since military authorities ordered soldiers not to keep any letters written them by their loved ones, the authors have done a magnificent service in obtaining letters that soldiers either surreptitiously hid or whose authors copied them before sending them on."--Library Journal.
