Through the worst years of the Great Depression as many as five thousand laborers toiled twenty-four hours a day, seven days a week, to erect the huge structure that would harness the Colorado River and transform the American West.Construction of the giant dam was a triumph of human ingenuity, yet the full story of this monumental endeavor has never been told. Now, in an engrossing, fast-paced narrative, Joseph E. Stevens recounts the gripping saga of Hoover Dam. Drawing on a wealth of material, including manuscript collections, government documents, contemporary newspaper and magazine accounts, and personal interviews and correspondence with men and women who were involved with the construction, he brings the Hoover Dam adventure to life.Described here in dramatic detail are the deadly hazards the work crews faced as they hacked and blasted the dam’s foundation out of solid rock; the bitter political battles and violent labor unrest that threatened to shut the job down; the deprivation and grinding hardship endured by the workers’ families; the dam builders’ gambling, drinking, and whoring sprees in nearby Las Vegas; and the stirring triumphs and searing moments of terror as the massive concrete wedge rose inexorably from the canyon floor.Here, too, is an unforgettable cast of characters: Henry Kaiser, Warren Bechtel, and Harry Morrison, the ambitious, headstrong construction executives who gambled fortune and fame on the Hoover Dam contract; Frank Crowe, the brilliant, obsessed field engineer who relentlessly drove the work force to finish the dam two and a half years ahead of schedule; Sims Ely, the irascible, teetotaling eccentric who ruled Boulder City, the straightlaced company town created for the dam workers by the federal government; and many more men and women whose courage and sacrifice, greed and frailty, made the dam’s construction a great human, as well as technological, adventure.Hoover Dam is a compelling, irresistible account of an extraordinary American epic.

    In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?Jared Diamond explores the diverse ways that new ideas emerge * Nassim Nicholas Taleb takes down the standard deviation * Richard Thaler and novelist Ian McEwan reveal the usefulness of "bad" ideas * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Physicist Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Alan Guth rethinks the origins of the universe * Sam Harris argues that our definition of science is too narrow * Nobel Prize winner Frank Wilczek disputes the division between mind and matter * Lawrence Krauss challenges the notion that the laws of physics were preordained * plus contributions from Daniel Goleman, Mihaly Csikszentmihalyi, Nicholas Carr, Rebecca Newberger Goldstein, Matt Ridley, Stewart Brand, Sean Carroll, Daniel C. Dennett, Helen Fisher, Douglas Rushkoff, Lee Smolin, Kevin Kelly, Freeman Dyson, and others.

    In the next ten years, change will happen even faster. As Hillary Clinton's Senior Advisor for Innovation, Alec Ross travelled nearly a million miles to forty-one countries, the equivalent of two round-trips to the moon. From refugee camps in the Congo and Syrian war zones, to visiting the world's most powerful people in business and government, Ross's travels amounted to a four-year masterclass in the changing nature of innovation. In The Industries of the Future, Ross distils his observations on the forces that are changing the world. He highlights the best opportunities for progress and explains how countries thrive or sputter. Ross examines the specific fields that will most shape our economic future over the next ten years, including robotics, artificial intelligence, the commercialization of genomics, cybercrime and the impact of digital technology. Blending storytelling and economic analysis, he answers questions on how we will need to adapt. Ross gives readers a vivid and informed perspective on how sweeping global trends are affecting the ways we live, now and tomorrow.

    The text provides a highly intuitive and practical understanding of the material by emphasizing the physics and the underlying physical phenomena involved. Using a reader-friendly approach and a conversational writing style, the book is self-instructive and entertains while it teaches. It shows that highly technical matter can be communicated effectively in a simple yet precise language.

    Not a master mason or carpenter, Filippo Brunelleschi was a goldsmith and clock maker. Over twenty-eight years, he would dedicate himself to solving puzzles of the dome's construction. In the process, he did nothing less than reinvent the field of architecture. He engineered the perfect placement of brick and stone (some among the most renowned machines of the Renaissance) to carry an estimated seventy million pounds hundreds of feet into the air, and designed the workers' platforms and routines so carefully that only one man died during the decades of construction. This drama was played out amid plagues, wars, political feuds, and the intellectual ferments of Renaissance Florence - events Ross King weaves into a story to great effect. An American Library Association Best Book of the Year Boston Globe: "An absorbing tale." Los Angeles Times: "Ross King has a knack for explaining complicated processes in a manner that is not only lucid but downright intriguing... Fascinating."

    It was to last five years and transform him from an amiable and somewhat aimless young man into a scientific celebrity. Even more vitally, it was to set in motion the intellectual currents that culminated in the arrival of The Origin of Species in Victorian drawing-rooms in 1859. His journal, reprinted here in a shortened version, is vivid and immediate, showing us a naturalist making patient observations, above all in geology. As well as a profusion of natural history detail, it records many other things that caught Darwin’s eye, from civil war in Argentina to the new colonial settlements of Australia. The editors have provided an excellent introduction and notes for this Penguin Classics edition, which also contains maps and appendices, including an essay on scientific geology and the Bible by Robert FitzRoy, Darwin’s friend and captain of the Beagle.

    It follows a more quantitative and design-oriented approach than other texts in the market, helping readers gain a better understanding of important concepts. They'll also discover how material properties relate to the process variables in a given process as well as how to perform manufacturing science and quantitative engineering analysis of manufacturing processes.

    In his classic The Age of Spiritual Machines, he argued that computers would soon rival the full range of human intelligence at its best. Now he examines the next step in this inexorable evolutionary process: the union of human and machine, in which the knowledge and skills embedded in our brains will be combined with the vastly greater capacity, speed, and knowledge-sharing ability of our creations.

    But the truth is far more sinister, says Austin Ruse. We're actually living in the age of the low information voter, easily mislead by all-too-convincing false statistics and studies. In Fact-Shaming, Ruse debunks so-called "facts" used to advance political causes one after the other, revealing how poorly they stand up to actual science.

    He’s taken sf to places it’s never been (Snow Crash, Anathem). He’s reinvented the historical novel (The Baroque Cycle), the international thriller (Reamde), and both at the same time (Cryptonomicon).Now he treats his legion of fans to Some Remarks, an enthralling collection of essays—Stephenson’s first nonfiction work since his long essay on technology, In the Beginning…Was the Command Line, more than a decade ago—as well as new and previously published short writings both fiction and non.Some Remarks is a magnificent showcase of a brilliantly inventive mind and talent, as he discourses on everything from Sir Isaac Newton to Star Wars.

    Its greatest detriment to the world has been its unfettered desire to play with and alter them: science for science's sake, as if it offered the only path to knowledge.According to Lehrer, when it comes to the human brain, the world of art unraveled such mysteries long before the neuroscientists: "This book is about artists who anticipated the discoveries of science who discovered truths about the human mind that science is only now discovering." 'Proust Was a Neuroscientist' is a dazzling inquiry into the nature of the mind and of the truths harvested by its first explorers: artists like Walt Whitman, George Eliot, Auguste Escoffier, Marcel Proust, Paul Cozanne, Igor Stravinsky, Gertrude Stein, and Virginia Woolf. What they understood intuitively and expressed through their respective art forms -- the fallibility of memory, the malleability of the brain, the subtleties of vision, and the deep structure of language -- science has only now begun to measure and confirm. Blending biography, criticism, and science writing, Lehrer offers a lucid examination of eight artistic thinkers who lit the path toward a greater understanding of the human mind and a deeper appreciation of the ineffable mystery of life.

    This riveting narrative offers an account of COVID-19, reminding us of women's leadership and resilience, reflecting back hope and humanity as we all figure out a new normal, together. Throughout history, men have fought, lost, and led us through the world's defining crises. That all changed with COVID-19. In Canada, women's presence in the response to the pandemic has been notable. Women are our nurses, doctors, PSWs. Our cashiers, long-haulers, cooks. In Canada, women are leading the fast-paced search for a vaccine. They are leading our provinces and territories. At home, they are leading families through self-isolation, often bearing the responsibility for their physical and emotional health. They are figuring out what working from home looks like, and many of them are doing it while homeschooling their kids. Women crafted the blueprint for kindness during the pandemic, from sewing masks to kicking off international mutual-aid networks. And, perhaps not surprisingly, women have also suffered some of the biggest losses, bearing the brunt of our economic skydive. Through intimate portraits of Canadian women in diverse situations and fields, Women of the Pandemic is a gripping narrative record of the early months of COVID-19, a clear-eyed look at women's struggles, which highlights their creativity, perseverance, and resilience as they charted a new path forward during impossible times.

    This engaging book--part scientific overview, part memoir, part futurist speculation--describes Koch's search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest--his instinctual (if "romantic") belief that life is meaningful.Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness (once considered a "fringy" subject) as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action.Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work--to uncover the roots of consciousness.
