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?

    . . except himself. Out of control of his actions, Billy Milligan was a man tormented by twenty-four distinct personalities battling for supremacy over his body—a battle that culminated when he awoke in jail, arrested for the kidnap and rape of three women. In a landmark trial, Billy was acquitted of his crimes by reason of insanity caused by multiple personality—the first such court decision in history—bringing to public light the most remarkable and harrowing case of multiple personality ever recorded.Twenty-four people live inside Billy Milligan. Philip, a petty criminal; Kevin, who dealt drugs and masterminded a drugstore robbery; April, whose only ambition was to kill Billy's stepfather; Adalana, the shy, lonely, affection-starved lesbian who “used” Billy's body in the rapes that led to his arrest; David, the eight-year-old “keeper of pain”; and all of the others, including men, women, several children, both boys and girls, and the Teacher, the only one who can put them all together. You will meet each in this often shocking true story. And you will be drawn deeply into the mind of this tortured young man and his splintered, terrifying world.

    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    In this masterfully written and brilliantly informed work of scientific history and explanation, Dr. Thorne, the Feynman Professor of Theoretical Physics at Caltech, leads his readers through an elegant, always human, tapestry of interlocking themes, coming finally to a uniquely informed answer to the great question: what principles control our universe and why do physicists think they know the things they think they know? Stephen Hawking's A Brief History of Time has been one of the greatest best-sellers in publishing history. Anyone who struggled with that book will find here a more slowly paced but equally mind-stretching experience, with the added fascination of a rich historical and human component.

    In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field—the study of life’s diversity and relatedness at the molecular level—is horizontal gene transfer (HGT), or the movement of genes across species lines. It turns out that HGT has been widespread and important. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection—a type of HGT.David Quammen chronicles these discoveries through the lives of the researchers who made them—such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about “mosaic” creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health.

    In this compelling memoir, his first wife, Jane Hawking, relates the inside story of their extraordinary marriage. As Stephen's academic renown soared, his body was collapsing under the assaults of a motor neuron disease. Jane's candid account of trying to balance his 24-hour care with the needs of their growing family reveals the inner strength of the author, while the self-evident character and achievements of her husband make for an incredible tale presented with unflinching honesty. Jane's candor is no less apparent when the marriage finally ends in a high-profile meltdown, with Stephen leaving Jane for one of his nurses and Jane marrying an old family friend. In this exceptionally open, moving, and often funny memoir, Jane Hawking confronts not only the acutely complicated and painful dilemmas of her first marriage, but also the relationship's fault lines exposed by the pervasive effects of fame and wealth. The result is a book about optimism, love, and change that will resonate with readers everywhere.

    Silver translates our most important, and often most obscure, scientific developments into a vernacular that is not only accessible and illuminating but also enjoyable. Silver makes his comprehensive case with much clarity and insight; his book aptly locates science as the apex of human reason, and reason as our best path to the truth. For all readers curious about--or else perhaps intimidated by--what Silver calls the scientific campaign up to now in his Preface, The Ascent of Science will be fresh, vivid, and fascinating reading.

    Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched. This is not some alternative universe but the realm of the very small, where quantum mechanics rules. In this weird world of atoms and their constituents, our common sense understanding of reality breaks down - yet quantum mechanics has never failed an experimental test. What does it all mean? For all its weirdness, quantum mechanics has given us many practical technologies including lasers and the transistors that underlie computers and all digital technology. In the future, it promises computers more powerful than any built before, the ability to communicate with absolute privacy, and even quantum teleportation. The Quantum World explores the past, present and future of quantum science, its applications and mind-bending implications. Discover how ideas from quantum mechanics are percolating out into the vast scale of the cosmos - perhaps, in the future, to reveal a new understanding of the big bang and the nature of space and time.ABOUT THE SERIESNew Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.

    Robert Oppenheimer, "father of the atomic bomb," the brilliant, charismatic physicist who led the effort to capture the awesome fire of the sun for his country in time of war. Immediately after Hiroshima, he became the most famous scientist of his generation-one of the iconic figures of the twentieth century, the embodiment of modern man confronting the consequences of scientific progress. He was the author of a radical proposal to place international controls over atomic materials-an idea that is still relevant today. He opposed the development of the hydrogen bomb and criticized the Air Force's plans to fight an infinitely dangerous nuclear war. In the now almost-forgotten hysteria of the early 1950s, his ideas were anathema to powerful advocates of a massive nuclear buildup, and, in response, Atomic Energy Commission chairman Lewis Strauss, Superbomb advocate Edward Teller and FBI director J. Edgar Hoover worked behind the scenes to have a hearing board find that Oppenheimer could not be trusted with America's nuclear secrets. American Prometheus sets forth Oppenheimer's life and times in revealing and unprecedented detail. Exhaustively researched, it is based on thousands of records and letters gathered from archives in America and abroad, on massive FBI files and on close to a hundred interviews with Oppenheimer's friends, relatives and colleagues.We follow him from his earliest education at the turn of the twentieth century at New York City's Ethical Culture School, through personal crises at Harvard and Cambridge universities. Then to Germany, where he studied quantum physics with the world's most accomplished theorists; and to Berkeley, California, where he established, during the 1930s, the leading American school of theoretical physics, and where he became deeply involved with social justice causes and their advocates, many of whom were communists. Then to Los Alamos, New Mexico, where he transformed a bleak mesa into the world's most potent nuclear weapons laboratory-and where he himself was transformed. And finally, to the Institute for Advanced Study in Princeton, which he directed from 1947 to 1966. American Prometheus is a rich evocation of America at midcentury, a new and compelling portrait of a brilliant, ambitious, complex and flawed man profoundly connected to its major events—the Depression, World War II and the Cold War. It is at once biography and history, and essential to our understanding of our recent past—and of our choices for the future.

    So here, Jim Al-Khalili and his crack team of experts bin the crystal ball and use cutting-edge science to get a glimpse of what's in store.From whether teleportation is really possible (spoiler: it is), to what we'll do if artificial intelligence takes over, What's Next? takes on the big questions. And along the way, it'll answer questions like: Will we find a cure to all diseases? An answer to climate change? Will bionics make us into superheroes?Touching on everything from genetics to transport, and nanotechnology to teleportation, What's Next? is a fascinating, fun and informative look at what's in store for the human race.

    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.

    Murder on a royal train. Divers dead of heatstroke at the bottom of an icy sea. An epidemic of insanity among the world's top scientists. This is the story of the great paradigm shifts of science, told as never before: in Sherlock Holmes adventures set amid the grandeur and squalor of Victorian London. Holmes, Watson, and other beloved characters created by Arthur Conan Doyle are challenged by mysteries, each of which hinges on a scientific paradox or principle. Colin Bruce has recreated the atmosphere of the original Sherlock Holmes stories to give a truly compulsive read. You won't even realize you've learned something until it's too late!
