His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century.Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

    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.

    The effects of homeopathy don’t go away under rigorous scientific conditions. The laws of nature aren’t what they used to be. Thirty years on, no one has an explanation for a seemingly intelligent signal received from outer space. The US Department of Energy is re-examining cold fusion because the experimental evidence seems too solid to ignore. The placebo effect is put to work in medicine while doctors can’t agree whether it even exists.In an age when science is supposed to be king, scientists are beset by experimental results they simply can’t explain. But, if the past is anything to go by, these anomalies contain the seeds of future revolutions. While taking readers on an entertaining tour d’horizon of the strangest of scientific findings – involving everything from our lack of free will to Martian methane that offers new evidence of life on the planet – Michael Brooks argues that the things we don’t understand are the key to what we are about to discover.This mind-boggling but entirely accessible survey of the outer limits of human knowledge is based on a short article by Michael Brooks for New Scientist magazine. It became the sixth most circulated story on the internet in 2005, and provoked widespread comment and compliments (Google “13 things that do not make sense” to see).Michael Brooks has now dug deeply into those mysteries, with extraordinary results.

    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.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    At the time, Watson was only 24, a young scientist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of science's greatest mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions & bitter rivalries. With humility unspoiled by false modesty, Watson relates his & Crick's desperate efforts to beat Linus Pauling to the Holy Grail of life sciences, the identification of the basic building block of life. Never has a scientist been so truthful in capturing in words the flavor of his work.

    It intersects with Darwin’s theory of evolution, and collides with the horrors of Nazi eugenics in the 1940s. The gene transforms post-war biology. It reorganizes our understanding of sexuality, temperament, choice and free will. This is a story driven by human ingenuity and obsessive minds – from Charles Darwin and Gregor Mendel to Francis Crick, James Watson and Rosalind Franklin, and the thousands of scientists still working to understand the code of codes.This is an epic, moving history of a scientific idea coming to life, by the author of The Emperor of All Maladies. But woven through The Gene, like a red line, is also an intimate history – the story of Mukherjee’s own family and its recurring pattern of mental illness, reminding us that genetics is vitally relevant to everyday lives. These concerns reverberate even more urgently today as we learn to “read” and “write” the human genome – unleashing the potential to change the fates and identities of our children.Majestic in its ambition, and unflinching in its honesty, The Gene gives us a definitive account of the fundamental unit of heredity – and a vision of both humanity’s past and future.

    Evolution, during the early nineteenth century, was an idea in the air. Other thinkers had suggested it, but no one had proposed a cogent explanation for how evolution occurs. Then, in September 1838, a young Englishman named Charles Darwin hit upon the idea that "natural selection" among competing individuals would lead to wondrous adaptations and species diversity. Twenty-one years passed between that epiphany and publication of "On the Origin of Species," The human drama and scientific basis of Darwin's twenty-one-year delay constitute a fascinating, tangled tale that elucidates the character of a cautious naturalist who initiated an intellectual revolution. "The Reluctant Mr. Darwin" is a book for everyone who has ever wondered about who this man was and what he said. Drawing from Darwin's secret "transmutation" notebooks and his personal letters, David Quammen has sketched a vivid life portrait of the man whose work never ceases to be controversial.

    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?

    Wilczek’s groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature. In fact, every major advance in his career came from this intuition: to assume that the universe embodies beautiful forms, forms whose hallmarks are symmetry—harmony, balance, proportion—and economy. There are other meanings of “beauty,” but this is the deep logic of the universe—and it is no accident that it is also at the heart of what we find aesthetically pleasing and inspiring.Wilczek is hardly alone among great scientists in charting his course using beauty as his compass. As he reveals in A Beautiful Question, this has been the heart of scientific pursuit from Pythagoras, the ancient Greek who was the first to argue that “all things are number,” to Galileo, Newton, Maxwell, Einstein, and into the deep waters of twentiethcentury physics. Though the ancients weren’t right about everything, their ardent belief in the music of the spheres has proved true down to the quantum level. Indeed, Wilczek explores just how intertwined our ideas about beauty and art are with our scientific understanding of the cosmos.Wilczek brings us right to the edge of knowledge today, where the core insights of even the craziest quantum ideas apply principles we all understand. The equations for atoms and light are almost literally the same equations that govern musical instruments and sound; the subatomic particles that are responsible for most of our mass are determined by simple geometric symmetries. The universe itself, suggests Wilczek, seems to want to embody beautiful and elegant forms. Perhaps this force is the pure elegance of numbers, perhaps the work of a higher being, or somewhere between. Either way, we don’t depart from the infinite and infinitesimal after all; we’re profoundly connected to them, and we connect them. When we find that our sense of beauty is realized in the physical world, we are discovering something about the world, but also something about ourselves.Gorgeously illustrated, A Beautiful Question is a mind-shifting book that braids the age-old quest for beauty and the age-old quest for truth into a thrilling synthesis. It is a dazzling and important work from one of our best thinkers, whose humor and infectious sense of wonder animate every page. Yes: The world is a work of art, and its deepest truths are ones we already feel, as if they were somehow written in our souls.

    Sixteen weeks later, Frank Borman, Jim Lovell, and Bill Anders were aboard the first manned spacecraft to depart Earth’s orbit, reach the moon, and return safely to Earth, delivering a tear-inducing Christmas Eve message along the way.

    Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria. Worse, these "too good to not be true" theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink their methods. Only by embracing reality as it is can science discover the truth.

    In all the current highly publicized debates about creationism and its descendant "intelligent design," there is an element of the controversy that is rarely mentioned—the "evidence," the empirical truth of evolution by natural selection. Even Richard Dawkins and Stephen Jay Gould, while extolling the beauty of evolution and examining case studies, have not focused on the evidence itself. Yet the proof is vast, varied, and magnificent, drawn from many different fields of science. Scientists are observing species splitting into two and are finding more and more fossils capturing change in the past—dinosaurs that have sprouted feathers, fish that have grown limbs. Why Evolution Is True weaves together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes first proposed by Darwin. In crisp, lucid prose accessible to a wide audience, Why Evolution Is True dispels common misunderstandings and fears about evolution and clearly confirms that this amazing process of change has been firmly established as a scientific truth.

    The result would be an unprecedented system of mass surveillance with the ability to pry into the private lives of every person on earth. Six years later, Snowden reveals for the very first time how he helped to build this system and why he was moved to expose it.Spanning the bucolic Beltway suburbs of his childhood and the clandestine CIA and NSA postings of his adulthood, Permanent Record is the extraordinary account of a bright young man who grew up online—a man who became a spy, a whistleblower, and, in exile, the Internet’s conscience. Written with wit, grace, passion, and an unflinching candor, Permanent Record is a crucial memoir of our digital age and destined to be a classic.

    Rather, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible. For the first time, Rise of the Rocket Girls tells the stories of these women--known as "human computers"--who broke the boundaries of both gender and science. Based on extensive research and interviews with all the living members of the team, Rise of the Rocket Girls offers a unique perspective on the role of women in science: both where we've been, and the far reaches of space to which we're heading.
