    A strong gravitational wave will briefly change that distance by less than the thickness of a human hair. We have perhaps less than a few tenths of a second to perform this measurement. And we don’t know if this infinitesimal event will come next month, next year or perhaps in thirty years.In 1916 Einstein predicted the existence of gravitational waves: miniscule ripples in the very fabric of spacetime generated by unfathomably powerful events. If such vibrations could somehow be recorded, we could observe our universe for the first time through sound: the hissing of the Big Bang, the whale-like tunes of collapsing stars, the low tones of merging galaxies, the drumbeat of two black holes collapsing into one. For decades, astrophysicists have searched for a way of doing so…In 2016 a team of hundreds of scientists at work on a billion-dollar experiment made history when they announced the first ever detection of a gravitational wave, confirming Einstein’s prediction. This is their story, and the story of the most sensitive scientific instrument ever made: LIGO.Based on complete access to LIGO and the scientists who created it, Black Hole Blues provides a firsthand account of this astonishing achievement: a compelling, intimate portrait of cutting-edge science at its most awe-inspiring and ambitious.

    The army blamed “human error†and a sordid love triangle. Though overshadowed by Three Mile Island, SL-1 remains the only fatal nuclear reactor incident in American history. Todd Tucker, who first heard the rumors about the Idaho Falls explosion as a trainee in the navy’s nuclear program, suspected there was more to the accident than rumors suggested. Poring over hundreds of pages of primary sources and interviewing survivors revealed that the army and its contractors had deliberately obscured the true cause of the accident, which resulted from poor engineering as much as uncontrolled passions. The National Reactor Testing Station, where the meltdown occurred, had been a proving ground where engineers, generals, and admirals attempted to realize the Atomic Age dream of unlimited power—amid the frantic race for nuclear power between the army, the navy, and the air force. The fruit of those ambitious plans included that of the nation’s unofficial nuclear patriarch, Admiral Rickover, whose “true submarine,†the USS Nautilus, would forever change naval warfare. But with the meltdown in Idaho came the end of the army’s program and the beginning of the navy’s long-standing monopoly on military nuclear power. Atomic America provides a fast-paced narrative history, advocating caution and accountability in harnessing nuclear energy.

    It remains the one of the most widely read books about science to come out of the twentieth century.(Note: the book was first published in 1934, in German, with the title Logik der Forschung. It was "reformulated" into English in 1959. See Wikipedia for details.)

    Full of insights, arguments and philosophical perspectives, the book covers an amazing array of topics. Beginning in antiquity with Democritus, it progresses through logic and set theory, computability and complexity theory, quantum computing, cryptography, the information content of quantum states and the interpretation of quantum mechanics. There are also extended discussions about time travel, Newcomb's Paradox, the anthropic principle and the views of Roger Penrose. Aaronson's informal style makes this fascinating book accessible to readers with scientific backgrounds, as well as students and researchers working in physics, computer science, mathematics and philosophy.

    It is a tale of rivers diverted and dammed, of political corruption and intrigue, of billion-dollar battles over water rights, of ecologic and economic disaster. In Cadillac Desert Marc Reisner writes of the earliest settlers, lured by the promise of paradise, and of the ruthless tactics employed by Los Angeles politicians and business interests to ensure the city's growth. He documents the bitter rivalry between two government giants, the Bureau of Reclamation and the U.S. Army Corps of Engineers, in the competition to transform the West.Based on more than a decade of research, Cadillac Desert is a stunning expose and a dramatic, intriguing history of the creation of an Eden—an Eden that may be only a mirage.

    Its author's engaging voice is one reason, and the compelling subjects he addresses is another; the nature of space and time, the role of God in creation, the history and future of the universe. But it is also true that in the years since its publication, readers have repeatedly told Professor Hawking of their great difficulty in understanding some of the book's most important concepts. This is the origin of and the reason for A Briefer History of Time: its author's wish to make its content more accessible to readers - as well as to bring it up-to-date with the latest scientific observations and findings.Although this book is literally somewhat "briefer", it actually expands on the great subjects of the original. Purely technical concepts, such as the mathematics of chaotic boundary conditions, are gone. Conversely, subjects of wide interest that were difficult to follow because they were interspersed throughout the book have now been given entire chapters of their own, including relativity, curved space, and quantum theory.This reorganization has allowed the authors to expand areas of special interest and recent progress, from the latest developments in string theory to exciting developments in the search for a complete unified theory of all the forces of physics. Like prior editions of the book - but even more so - A Briefer History of Time will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space. Thirty-seven full-color illustrations enhance the text and make A Briefer History of Time an exhilarating addition in its own right to the literature of science.

    But a growing number of experts are sounding a different kind of alarm. Rather than growing exponentially, they argue, the global population is headed for a steep decline.Throughout history, depopulation was the product of catastrophe: ice ages, plagues, the collapse of civilizations. This time, however, we're thinning ourselves deliberately, by choosing to have fewer babies than we need to replace ourselves. In much of the developed and developing world, that decline is already underway, as urbanization, women's empowerment, and waning religiosity lead to smaller and smaller families. In Empty Planet, Ibbitson and Bricker travel from South Florida to Sao Paulo, Seoul to Nairobi, Brussels to Delhi to Beijing, drawing on a wealth of research and firsthand reporting to illustrate the dramatic consequences of this population decline--and to show us why the rest of the developing world will soon join in.They find that a smaller global population will bring with it a number of benefits: fewer workers will command higher wages; good jobs will prompt innovation; the environment will improve; the risk of famine will wane; and falling birthrates in the developing world will bring greater affluence and autonomy for women. But enormous disruption lies ahead, too. We can already see the effects in Europe and parts of Asia, as ageing populations and worker shortages weaken the economy and impose crippling demands on healthcare and social security. The United States is well-positioned to successfully navigate these coming demographic shifts--that is, unless growing isolationism and anti-immigrant backlash lead us to close ourselves off just as openness becomes more critical to our survival than ever before.Rigorously researched and deeply compelling, Empty Planet offers a vision of a future that we can no longer prevent--but one that we can shape, if we choose.

    What is the psychological mechanism that allows us to know something is true but act as if it is not? George Marshall’s search for the answers brings him face to face with Nobel Prize–winning psychologists and Texas Tea Party activists; the world’s leading climate scientists and those who denounce them; liberal environmentalists and conservative evangelicals. What he discovers is that our values, assumptions, and prejudices can take on lives of their own, gaining authority as they are shared, dividing people in their wake.With engaging stories and drawing on years of his own research, Marshall argues that the answers do not lie in the things that make us different, but rather in what we share: how our human brains are wired—our evolutionary origins, our perceptions of threats, our cognitive blind spots, our love of storytelling, our fear of death, and our deepest instincts to defend our family and tribe. Once we understand what excites, threatens, and motivates us, we can rethink climate change, for it is not an impossible problem. Rather, we can halt it if we make it our common purpose and common ground. In the end, Don’t Even Think About It is both about climate change and about the qualities that make us human and how we can deal with the greatest challenge we have ever faced.

    In Unruly Places, Alastair Bonnett goes to some of the most unexpected, offbeat places in the world to reinspire our geographical imagination.Bonnett’s remarkable tour includes moving villages, secret cities, no man’s lands, and floating islands. He explores places as disorienting as Sandy Island, an island included on maps until just two years ago despite the fact that it never existed. Or Sealand, an abandoned gun platform off the English coast that a British citizen claimed as his own sovereign nation, issuing passports and crowning his wife as a princess. Or Baarle, a patchwork of Dutch and Flemish enclaves where walking from the grocery store’s produce section to the meat counter can involve crossing national borders.An intrepid guide down the road much less traveled, Bonnett reveals that the most extraordinary places on earth might be hidden in plain sight, just around the corner from your apartment or underfoot on a wooded path. Perfect for urban explorers, wilderness ramblers, and armchair travelers struck by wanderlust, Unruly Places will change the way you see the places you inhabit.

    In Denialism, New Yorker staff writer Michael Specter reveals that Americans have come to mistrust institutions and especially the institution of science more today than ever before. For centuries, the general view had been that science is neither good nor bad—that it merely supplies information and that new information is always beneficial. Now, science is viewed as a political constituency that isn’t always in our best interest. We live in a world where the leaders of African nations prefer to let their citizens starve to death rather than import genetically modified grains. Childhood vaccines have proven to be the most effective public health measure in history, yet people march on Washington to protest their use. In the United States a growing series of studies show that dietary supplements and “natural” cures have almost no value, and often cause harm. We still spend billions of dollars on them. In hundreds of the best universities in the world, laboratories are anonymous, unmarked, and surrounded by platoons of security guards—such is the opposition to any research that includes experiments with animals. And pharmaceutical companies that just forty years ago were perhaps the most visible symbol of our remarkable advance against disease have increasingly been seen as callous corporations propelled solely by avarice and greed. As Michael Specter sees it, this amounts to a war against progress. The issues may be complex but the choices are not: Are we going to continue to embrace new technologies, along with acknowledging their limitations and threats, or are we ready to slink back into an era of magical thinking? In Denialism, Specter makes an argument for a new Enlightenment, the revival of an approach to the physical world that was stunningly effective for hundreds of years: What can be understood and reliably repeated by experiment is what nature regarded as true. Now, at the time of mankind’s greatest scientific advances—and our greatest need for them—that deal must be renewed.

    Britons opted to leave the European Union. Far-right, populist politicians channeling anger at out-of-touch “elites” are gaining ground across Europe. In vote after shocking vote, citizens of Western democracies have pushed their anger to the top of their governments’ political agendas. The votes have varied in their particulars, but their unifying feature has been rejection of moderation, incrementalism, and the status quo.Amid this roiling international scene, Canada appears placid, at least on the surface. As other societies retrench, the international media have taken notice of Canada’s welcome of Syrian refugees, its half-female federal cabinet, and its acceptance of climate science and mixed efforts to limit its emissions. After a year in power, the centrist federal government continues to enjoy majority approval, suggesting an electorate not as bitterly split as the ones to the south or in Europe.As sceptics point out, however, Brexit and a Trump presidency were unthinkable until they happened. Could it be that Canada is not immune to the same forces of populism, social fracture, and backlash that have afflicted other parts of the world? Our largest and most cosmopolitan city elected Rob Ford. Conservative Party leadership hopeful Kellie Leitch proposes a Canadian values test for immigrants and has called the Trump victory “exciting.” Anti-tax demonstrators in Alberta chanted “lock her up” in reference to Premier Rachel Notley, an elected leader accused of no wrongdoing, only policy positions the protesters disliked.Pollster and social values researcher Michael Adams takes Canadians into the examining room to see whether we are at risk of coming down with the malaise affecting other Western democracies. Drawing on major social values surveys of Canadians and Americans in 2016—as well as decades of tracking data in both countries—Adams examines our economy, institutions, and demographics to answer the question: could it happen here?

    And through CODE, we see how this ingenuity and our very human compulsion to communicate have driven the technological innovations of the past two centuries. Using everyday objects and familiar language systems such as Braille and Morse code, author Charles Petzold weaves an illuminating narrative for anyone who’s ever wondered about the secret inner life of computers and other smart machines. It’s a cleverly illustrated and eminently comprehensible story—and along the way, you’ll discover you’ve gained a real context for understanding today’s world of PCs, digital media, and the Internet. No matter what your level of technical savvy, CODE will charm you—and perhaps even awaken the technophile within.

    Charles Perrow argues that the conventional engineering approach to ensuring safety--building in more warnings and safeguards--fails because systems complexity makes failures inevitable. He asserts that typical precautions, by adding to complexity, may help create new categories of accidents. (At Chernobyl, tests of a new safety system helped produce the meltdown and subsequent fire.) By recognizing two dimensions of risk--complex versus linear interactions, and tight versus loose coupling--this book provides a powerful framework for analyzing risks and the organizations that insist we run them.The first edition fulfilled one reviewer's prediction that it may mark the beginning of accident research. In the new afterword to this edition Perrow reviews the extensive work on the major accidents of the last fifteen years, including Bhopal, Chernobyl, and the Challenger disaster. The new postscript probes what the author considers to be the quintessential 'Normal Accident' of our time: the Y2K computer problem.
