The only question is when. In the meantime, we need to get much better at finding objects hurtling our way, and if they’re large enough to penetrate the atmosphere without burning up, figure out what to do about them. We owe many of science’s most important discoveries to the famed Meteor Crater, a mile-wide dimple on the Colorado Plateau created by an asteroid hit 50,000 years ago. In his masterfully researched Fire in the Sky, Dillow unpacks what the Crater has to tell us. Prior to the early 1900s, the world believed that all craters—on the Earth and Moon—were formed by volcanic activity. Not so. The revelation that Meteor Crater and others like it were formed by impacts with space objects has led to a now accepted theory about what killed off the dinosaurs, and it has opened up a new field of asteroid observation, which has recently brimmed with urgency. Dillow looks at great asteroid hits of the past and spends time with modern-day asteroid hunters and defense planning experts, including America’s first Planetary Defense Officer. Satellite sensors confirm that a Hiroshima-scale blast occurs in the atmosphere every year, and a smaller, one-kiloton blast every month. While Dillow makes clear that the objects above can be deadly, he consistently inspires awe with his descriptions of their size, makeup, and origins. At once a riveting work of popular science and a warning to not take for granted the space objects hurtling overhead, Fire in the Sky is, above all, a testament to our universe’s celestial wonders.

      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.

    He begins with Copernicus, during the Renaissance, when science replaced mysticism as a means of explaining the workings of the world, and he continues through the centuries, creating an unbroken genealogy of not only the greatest but also the more obscure names of Western science, a dot-to-dot line linking amateur to genius, and accidental discovery to brilliant deduction.By focusing on the scientists themselves, Gribbin has written an anecdotal narrative enlivened with stories of personal drama, success and failure. A bestselling science writer with an international reputation, Gribbin is among the few authors who could even attempt a work of this magnitude. Praised as “a sequence of witty, information-packed tales” and “a terrifi c read” by The Times upon its recent British publication, The Scientists breathes new life into such venerable icons as Galileo, Isaac Newton, Albert Einstein and Linus Pauling, as well as lesser lights whose stories have been undeservedly neglected. Filled with pioneers, visionaries, eccentrics and madmen, this is the history of science as it has never been told before.From the Hardcover edition.

    Efforts to gain access to the site of catastrophic radiation damage were denied, and the residents of Chernobyl were given no answers as their lives hung in the balance. Drawing on a decade of archival research and on-the-ground interviews in Ukraine, Russia, and Belarus, Kate Brown unveils the full breadth of the devastation and the whitewash that followed. Her findings make clear the irreversible impact of man-made radioactivity on every living thing; and hauntingly, they force us to confront the untold legacy of decades of weapons-testing and other catastrophic nuclear incidents.

    There's a lot for astronomers to be smug about. But when it comes to understanding how the Universe began and grew up we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the Universe.This brief but far-reaching period in the Universe's history, known to astrophysicists as the 'Epoch of Reionisation', represents the start of the cosmos as we experience it today. The time when the very first stars burst into life, when darkness gave way to light. After hundreds of millions of years of dark, uneventful expansion, one by the one these stars suddenly came into being. This was the point at which the chaos of the Big Bang first began to yield to the order of galaxies, black holes and stars, kick-starting the pathway to planets, to comets, to moons, and to life itself.Incorporating the very latest research into this branch of astrophysics, this book sheds light on this time of darkness, telling the story of these first stars, hundreds of times the size of the Sun and a million times brighter, lonely giants that lived fast and died young in powerful explosions that seeded the Universe with the heavy elements that we are made of. Emma Chapman tells us how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers a first-hand look at the immense telescopes about to come on line to peer into the past, searching for the echoes and footprints of these stars, to take this period in the Universe's history from the realm of theoretical physics towards the wonder of observational astronomy.

    But having developed that power, humans are also able to leave Earth and voyage into the vastness of space. After millions of years of evolution, we’ve arrived at the point where we can settle other worlds and begin the process of becoming multi-planetary. How did we get here? What does the future hold for us? Divided into four accessible sections, Beyond the Known examines major periods of discovery and rediscovery, from Classical Times, when Phoenicians, Persians and Greeks ventured forth; to The Age of European Exploration, which saw colonies sprout on nearly continent; to The Era of Scientific Inquiry, when researchers developed brand new tools for mapping and traveling farther; to Our Spacefaring Future, which unveils plans currently underway for settling other planets and, eventually, traveling to the stars. A Mission Manager at SpaceX with a light, engaging voice, Andrew Rader is at the forefront of space exploration. As a gifted historian, Rader, who has won global acclaim for his stunning breadth of knowledge, is singularly positioned to reveal the story of human exploration that is also the story of scientific achievement. Told with an infectious zeal for traveling beyond the known, Beyond the Known illuminates how very human it is to emerge from the cave and walk toward an infinitely expanding horizon.

    government faced many difficult decisions, including what to do with the Third Reich’s scientific minds. These were the brains behind the Nazis’ once-indomitable war machine. So began Operation Paperclip, a decades-long, covert project to bring Hitler’s scientists and their families to the United States.Many of these men were accused of war crimes, and others had stood trial at Nuremberg; one was convicted of mass murder and slavery. They were also directly responsible for major advances in rocketry, medical treatments, and the U.S. space program. Was Operation Paperclip a moral outrage, or did it help America win the Cold War?Drawing on exclusive interviews with dozens of Paperclip family members, colleagues, and interrogators, and with access to German archival documents (including previously unseen papers made available by direct descendants of the Third Reich’s ranking members), files obtained through the Freedom of Information Act, and dossiers discovered in government archives and at Harvard University, Annie Jacobsen follows more than a dozen German scientists through their postwar lives and into a startling, complex, nefarious, and jealously guarded government secret of the twentieth century.In this definitive, controversial look at one of America’s most strategic, and disturbing, government programs, Jacobsen shows just how dark government can get in the name of national security.

    T-Minus: The Race to the Moon is the story of the people who made it happen, both in the rockets and behind the scenes.

    What neither he nor anyone else had counted on was a door that refused to open. But that is the nature of spaceflight--anything can, and sometimes does, go wrong. Ultimately, Jones spent fifty-two days orbiting Earth, including more than nineteen hours outside during extravehicular activity--that is, sky walking.

    As recounted by Ben Rich, the operation's brilliant boss for nearly two decades, the chronicle of Lockheed's legendary Skunk Works is a drama of cold war confrontations and Gulf War air combat, of extraordinary feats of engineering & achievement against fantastic odds. Here are up-close portraits of the maverick band of scientists & engineers who made the Skunk Works so renowned. Filled with telling personal anecdotes & high adventure, with narratives from the CIA & from Air Force pilots who flew the many classified, risky missions, this book is a portrait of the most spectacular aviation triumphs of the 20th century.

    But what would it look like to study the whole of history, from the big bang through the present day -- and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence?These were the questions David Christian set out to answer when he created the field of "Big History," the most exciting new approach to understanding where we have been, where we are, and where we are going. In Origin Story, Christian takes readers on a wild ride through the entire 13.8 billion years we've come to know as "history." By focusing on defining events (thresholds), major trends, and profound questions about our origins, Christian exposes the hidden threads that tie everything together -- from the creation of the planet to the advent of agriculture, nuclear war, and beyond.With stunning insights into the origin of the universe, the beginning of life, the emergence of humans, and what the future might bring, Origin Story boldly reframes our place in the cosmos.

    Dubbed the AK-47, it was selected as the Eastern Bloc's standard arm. Scoffed at in the Pentagon as crude and unimpressive, it was in fact a breakthrough--a compact automatic that could be mastered by almost anyone, last decades in the field, and would rarely jam. Manufactured by tens of millions in planned economies, it became first an instrument of repression and then the most lethal weapon of the Cold War. Soon it was in the hands of terrorists.In a searing examination of modern conflict and official folly, C. J. Chivers mixes meticulous historical research, investigative reporting, and battlefield reportage to illuminate the origins of the world's most abundant firearm and the consequences of its spread. The result, a tour de force of history and storytelling, sweeps through the miniaturization and distribution of automatic firepower, and puts an iconic object in fuller context than ever before. "The Gun "dismantles myths as it moves from the naive optimism of the Industrial Revolution through the treacherous milieu of the Soviet Union to the inside records of the Taliban. Chivers tells of the 19th-century inventor in Indianapolis who designs a Civil War killing machine, insisting that more-efficient slaughter will save lives. A German attache who observes British machine guns killing Islamic warriors along the Nile advises his government to amass the weapons that would later flatten British ranks in World War I. In communist Hungary, a locksmith acquires an AK-47 to help wrest his country from the Kremlin's yoke, beginning a journey to the gallows. The Pentagon suppresses the results of firing tests on severed human heads that might have prevented faulty rifles from being rushed to G.I.s in Vietnam. In Africa, a millennial madman arms abducted children and turns them on their neighbors, setting his country ablaze. Neither pro-gun nor anti-gun, "The Gun "builds to a terrifying sequence, in which a young man who confronts a trio of assassins is shattered by 23 bullets at close range. The man survives to ask questions that Chivers examines with rigor and flair.Throughout, "The Gun "animates unforgettable characters--inventors, salesmen, heroes, megalomaniacs, racists, dictators, gunrunners, terrorists, child soldiers, government careerists, and fools. Drawing from years of research, interviews, and from declassified records revealed for the first time, he presents a richly human account of an evolution in the very experience of war.

    While not every story is concerned with the hard science behind space travel and other futuristic ventures, fiction can give listeners an amazing insight into what people could be capable of and what people dream of doing.In the 10 lectures of The Science of Sci-Fi: From Warp Speed to Interstellar Travel, Professor Erin Macdonald interweaves real science and the achievements of the imagination to reveal the truth that underlies favorite stories and sheds light on what the future may hold. From faster-than-light travel to journeys through time itself, science fiction makes humanity seem limitless. So, what scientific boundaries are people pushing against while seeking to fly among the stars?Listening Length: 3 hours and 59 minutes

    There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "big bang," determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned," there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.
