Each chapter explores a different phenomenon, explaining it in easy-to-understand terms, and considering how life on earth and the planet itself would be affected should the event come to pass. Rather than sensationalizing the information, Plait analyzes the probability of these catastrophes occurring in our lifetimes and what we can do to stop them. With its entertaining tone and enlightening explanation of unfathomable concepts, Death from the Skies! will appeal to science buffs and beginners alike.

    The black mass crashed through the local school. 144 people were killed. 116 were schoolchildren. Gaynor Madgwick was there. She was eight and severely injured. In this book, Gaynor tells her own story and interviews people affected by the day's events. "Gaynor Madgwick was pulled injured from one of the classrooms where her friends died. She was left behind to live out her life. This is her story, sad, sweet, sentimental, and authentic. I commend it to you." - Vincent Kane, Broadcaster "Gaynor Madgwick's sense of injustice is palpable in her clear, riveting account of this scandal and its human cost. Despite everything, however, she is not bitter and retains the quiet dignity that is, perhaps, the true and lasting legacy of Aberfan." - Frank Olding, Planet Magazine "Madgwick does not dwell too much on the politics of Aberfan, and this is left largely to an incisive introduction by the veteran broadcaster, Vincent Kane, who leaves us in no doubt where the responsibility lay for the disaster. Thankfully Madgwick has now found happiness after a troubled life, having had to live with the guilt of the survivor for all her life. And writing so sensitively has helped her to come to terms with what happened in 1966. This is certainly not an easy book to read, but as noted by Lord Snowdon, it should and must be read by all of us in memory of those who died, whilst not forgetting those who also survived this tragic event." - Richard E. Huws, Gwales

    Yet for all the talk about the democratizing power of the Internet, regimes in Iran and China are as stable and repressive as ever. In fact, authoritarian governments are effectively using the Internet to suppress free speech, hone their surveillance techniques, disseminate cutting-edge propaganda, and pacify their populations with digital entertainment. Could the recent Western obsession with promoting democracy by digital means backfire?In this spirited book, journalist and social commentator Evgeny Morozov shows that by falling for the supposedly democratizing nature of the Internet, Western do-gooders may have missed how it also entrenches dictators, threatens dissidents, and makes it harder - not easier - to promote democracy. Buzzwords like "21st-century statecraft" sound good in PowerPoint presentations, but the reality is that "digital diplomacy" requires just as much oversight and consideration as any other kind of diplomacy.Marshaling compelling evidence, Morozov shows why we must stop thinking of the Internet and social media as inherently liberating and why ambitious and seemingly noble initiatives like the promotion of "Internet freedom" might have disastrous implications for the future of democracy as a whole.

    NASA’s Space Shuttle Columbia was the most advanced flying machine ever built – the high watermark of post-war aviation development. A direct descendant of the record-breaking X-planes the likes of which Chuck Yeager had tested in the skies over the Mojave Desert, Columbia was a winged rocket plane, the size of an airliner, capable of flying to space and back before being made ready to fly again. She was the world’s first real spaceship.On board were men with the Right Stuff. The Shuttle’s Commander, moonwalker John Young, was already a veteran of five spaceflights. Alongside him, Pilot Bob Crippen was making his first, but Crip, taken in by the space agency after the cancellation of a top secret military space station programme in 1969, had worked on the Shuttle’s development for a decade. Never before had a crew been so well prepared for their mission.Yet less than an hour after Young and Crippen’s spectacular departure from the Cape it was clear that all was not well. Tiles designed to protect Columbia from the blowtorch burn of re-entry were missing from the heatshield. If the damage to their ship was too great the astronauts would be unable to return safely to earth. But neither they nor mission control possessed any way of knowing. Instead, NASA turned to the National Reconnaissance Office, a spy agency hidden deep inside the Pentagon whose very existence was classified. To help, the NRO would attempt something that had never been done before. Success would require skill, pinpoint timing and luck …Drawing on brand new interviews with astronauts and engineers, archive material and newly declassified documents, Rowland White, bestselling author of Vulcan 607, has pieced together the dramatic untold story of the mission for the first time. Into the Black is a thrilling race against time; a gripping high stakes cold-war story, and a celebration of a beyond the state-of-the-art machine that, hailed as one of the seven new wonders of the world, rekindled our passion for spaceflight.*With a foreword by Astronaut Richard Truly*‘Beautifully researched and written, Into the Black tells the true, complete story of the Space Shuttle better than it’s ever been told before.’ Colonel Chris Hadfield, former Astronaut and Space Station Commander‘Brilliantly revealed, Into the Black is the finely tuned true story of the first flight of the Space Shuttle Columbia. Rowland White has magnificently laid bare the unknown dangers and unseen hazards of that first mission … Once read, not forgotten.’Clive Cussler

    But concern over what Louis Brandeis called the "curse of bigness" can no longer remain the province of specialist lawyers and economists, for it has spilled over into policy and politics, even threatening democracy itself. History suggests that tolerance of inequality and failing to control excessive corporate power may prompt the rise of populism, nationalism, extremist politicians, and fascist regimes. In short, as Wu warns, we are in grave danger of repeating the signature errors of the twentieth century.In The Curse of Bigness, Columbia professor Tim Wu tells of how figures like Brandeis and Theodore Roosevelt first confronted the democratic threats posed by the great trusts of the Gilded Age--but the lessons of the Progressive Era were forgotten in the last 40 years. He calls for recovering the lost tenets of the trustbusting age as part of a broader revival of American progressive ideas as we confront the fallout of persistent and extreme economic inequality.

    individual whose contributions to the scientific, business and cultural realms are extensive."—BookpageBefore slim laptops that fit into briefcases, computers looked like strange, alien vending machines.

    The computer programmer, the doctor, the artist, and even the parent and citizen all engage in a craftsman’s work. In this thought-provoking book, Sennett explores the work of craftsmen past and present, identifies deep connections between material consciousness and ethical values, and challenges received ideas about what constitutes good work in today’s world. The Craftsman engages the many dimensions of skill—from the technical demands to the obsessive energy required to do good work. Craftsmanship leads Sennett across time and space, from ancient Roman brickmakers to Renaissance goldsmiths to the printing presses of Enlightenment Paris and the factories of industrial London; in the modern world he explores what experiences of good work are shared by computer programmers, nurses and doctors, musicians, glassblowers, and cooks. Unique in the scope of his thinking, Sennett expands previous notions of crafts and craftsmen and apprises us of the surprising extent to which we can learn about ourselves through the labor of making physical things.
