Available in PDF, EPUB and Kindle. Book excerpt: The whole story of laser weapons with a focus on its many interesting characters and sometimes bizarre schemes The laser--a milestone invention of the mid-twentieth century--quickly captured the imagination of the Pentagon as the key to the ultimate weapon. Veteran science writer Jeff Hecht tells the inside story of the adventures and misadventures of scientists and military strategists as they exerted Herculean though often futile efforts to adapt the laser for military uses. From the 1950s' sci-fi vision of the death ray, through the Reagan administration's Star Wars missile defense system, to more promising developments today, Hecht provides an entertaining history. As the author illustrates, there has always been a great deal of enthusiasm and false starts surrounding lasers. He describes a giant laser that filled a Boeing 747, lasers powered like rocket engines, plans for an orbiting fleet of robotic laser battle stations to destroy nuclear missiles, claims that nuclear bombs could produce intense X-ray laser beams, and a scheme to bounce laser beams off giant orbiting relay mirrors. Those far-out ideas remain science fiction. Meanwhile, in civilian sectors, the laser is already being successfully used in fiber optic cables, scanners, medical devices, and industrial cutting tools. Now those laser cutting tools are leading to a new generation of laser weapons that just might stop insurgent rockets. Replete with interesting characters, bizarre schemes, and wonderful inventions, this is a well-told tale about the evolution of technology and the reaches of human ambition.

Download or read book The Laser That s Changing the World written by Todd Neff and published by . This book was released on 2018 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tells the story of a laser technology that will have a big impact on society and the brilliant innovators responsible for its developmentLidar--a technology evolved from radar, but using laser light rather than microwaves--has found an astounding range of applications, none more prominent than its crucial role in enabling self-driving cars. This accessible introduction to a fascinating and increasingly vital technology focuses on the engaging human stories of lidar's innovators as they advance and adapt it to better understand air, water, ice and Earth - not to mention mapping Mars and Mercury, spotting incoming nuclear warheads, and avoiding pedestrians and cyclists on city streets.Award-winning science writer Todd Neff invites readers behind the scenes to meet some of the great innovators who have explored and expanded the uses of this amazing technology: people like MIT scientist Louis Smullin, whose lidar bounced light off the moon soon after the laser's invention; Allan Carswell, who plumbed the shallows of Lake Erie en route to developing the aerial lidar now essential for coastal mapping and hurricane damage assessment; Red Whittaker, the field robotics pioneer who was putting lidar on his autonomous contraptions as early as the 1980s; and David Hall, whose laser sombrero on a Toyota Tundra gave birth to modern automotive lidar.These are just some of the stories Neff tells before looking ahead to a future that could bring lidar to unpiloted air taxis, to the contaminated pipes of the U.S. nuclear weapons complex, and to satellites capable of pinpointing greenhouse gas sources from orbit. As the author makes clear, the sky is no limit with lidar, which promises to make our world safer, healthier, and vastly more interesting.

Download or read book Blindsight written by Peter Watts and published by Macmillan. This book was released on 2006-10-03 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hugo and Shirley Jackson award-winning Peter Watts stands on the cutting edge of hard SF with his acclaimed novel, Blindsight Two months since the stars fell... Two months of silence, while a world held its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Download or read book Dark Skies written by Daniel Deudney and published by Oxford University Press. This book was released on 2020-03-02 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space is again in the headlines. E-billionaires Jeff Bezos and Elon Musk are planning to colonize Mars. President Trump wants a "Space Force" to achieve "space dominance" with expensive high-tech weapons. The space and nuclear arms control regimes are threadbare and disintegrating. Would-be asteroid collision diverters, space solar energy collectors, asteroid miners, and space geo-engineers insistently promote their Earth-changing mega-projects. Given our many looming planetary catastrophes (from extreme climate change to runaway artificial superintelligence), looking beyond the earth for solutions might seem like a sound strategy for humanity. And indeed, bolstered by a global network of fervent space advocates-and seemingly rendered plausible, even inevitable, by oceans of science fiction and the wizardly of modern cinema-space beckons as a fully hopeful path for human survival and flourishing, a positive future in increasingly dark times. But despite even basic questions of feasibility, will these many space ventures really have desirable effects, as their advocates insist? In the first book to critically assess the major consequences of space activities from their origins in the 1940s to the present and beyond, Daniel Deudney argues in Dark Skies that the major result of the "Space Age" has been to increase the likelihood of global nuclear war, a fact conveniently obscured by the failure of recognize that nuclear-armed ballistic missiles are inherently space weapons. The most important practical finding of Space Age science, also rarely emphasized, is the discovery that we live on Oasis Earth, tiny and fragile, and teeming with astounding life, but surrounded by an utterly desolate and inhospitable wilderness stretching at least many trillions of miles in all directions. As he stresses, our focus must be on Earth and nowhere else. Looking to the future, Deudney provides compelling reasons why space colonization will produce new threats to human survival and not alleviate the existing ones. That is why, he argues, we should fully relinquish the quest. Mind-bending and profound, Dark Skies challenges virtually all received wisdom about the final frontier.

Download or read book Countdown written by Sarah Scoles and published by Bold Type Books. This book was released on 2024-02-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: For fans of Oppenheimer, a riveting investigation into the modern nuclear weapons landscape. Nuclear weapons are, today, as important as they were during the Cold War, and some experts say we could be as close to a nuclear catastrophe now as we were at the height of that conflict. Despite that, conversations about these bombs generally often happen in past tense. In Countdown, science journalist Sarah Scoles uncovers a different atomic reality: the nuclear age’s present. Drawing from years of on-the-ground reporting at the nation's nuclear weapons labs, Scoles interrogates the idea that having nuclear weapons keeps us safe, deterring attacks and preventing radioactive warfare. She deftly assesses the existing nuclear apparatus in the United States, taking readers beyond the news headlines and policy-speak to reveal the state of nuclear-weapons technology, as well as how people currently working within the U.S. nuclear weapons complex have come to think about these bombs and the idea that someone, someday, might use them. Through a sharp, surprising, and undoubtedly urgent narrative, Scoles brings us out of the Cold War and into the twenty-first century, opening readers' eyes to the true nature of nuclear weapons and their caretakers while also giving us the context necessary to understand the consequences of their existence, for worse and for better, for now and for the future.
