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.

This book tells the story of a unique scientific and human adventure, following the life and science of Bruno Touschek, an Austrian born physicist, who conceived and built AdA, the first matter-antimatter colliding-beam storage ring, the ancestor of the Large Hadron Collider at CERN where the Higgs Boson was discovered in 2012. Making extensive use of archival sources and personal correspondence, the author offers for the first time a unified history of European efforts to build modern-day particle accelerators, from the dark times of war-ravaged Europe up to the rebuilding of science in Germany, UK, Italy and France through the 1950s and early 1960s. This book, the result of several years of scholarly research work, includes numerous previously unpublished photos as well as original drawings by Bruno Touschek.

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.

This collection presents new work in risk media studies from critical humanities perspectives. Defining, historicizing, and consolidating current scholarship, the volume seeks to shape an emerging field, signposting its generative insights while examining its implicit assumptions. When and under what conditions does risk emerge? How is risk mediated? Who are the targets of risk media? Who manages risk? Who lives with it? Who are most in danger? Such questions—the what, how, who, when, and why of risk media—inform the scope of this volume. With roots in critical media studies and science and technology studies, it hopes to inspire new questions, perspectives, frameworks, and analytical tools not only for risk, media, and communication studies, but also for social and cultural theories. Editors Bishnupriya Ghosh and Bhaskar Sarkar bring together contributors who elucidate and interrogate risk media’s varied histories and futures. This book is meant for students and scholars of media and communication studies, science and technology studies, and the interdisciplinary humanities, looking either to deepen their engagement with risk media or to broaden their knowledge of this emerging field.

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.

This important U.S. strategic studies work seeks to develop a cyber deterrence strategy by drawing upon the hard-learned lessons of the past—specifically from Cold War deterrence theory and Cold War missile defense. Ultimately, a strongpoint defense is proposed along with a decentralized and further hardened critical infrastructure approach that continually exploits emergent innovation opportunities through investment in research.
