    Called a madman by his enemies, a genius by others, and an enigma by nearly everyone, Nikola Tesla was, without a doubt, a trailblazing inventor who created astonishing, sometimes world-transforming devices that were virtually without theoretical precedent. Tesla not only discovered the rotating magnetic field -- the basis of most alternating-current machinery -- but also introduced us to the fundamentals of robotics, computers, and missile science. Almost supernaturally gifted, unfailingly flamboyant and neurotic, Tesla was troubled by an array of compulsions and phobias and was fond of extravagant, visionary experimentations. He was also a popular man-about-town, admired by men as diverse as Mark Twain and George Westinghouse, and adored by scores of society beauties. From Tesla's childhood in Yugoslavia to his death in New York in the 1940s, Cheney paints a compelling human portrait and chronicles a lifetime of discoveries that radically altered -- and continue to alter -- the world in which we live. Tesla: Man Out of Time is an in-depth look at the seminal accomplishments of a scientific wizard and a thoughtful examination of the obsessions and eccentricities of the man behind the science.

    Julian Assange, the editor-in-chief of and visionary behind WikiLeaks, has been a leading voice in the cypherpunk movement since its inception in the 1980s.Now, in what is sure to be a wave-making new book, Assange brings together a small group of cutting-edge thinkers and activists from the front line of the battle for cyber-space to discuss whether electronic communications will emancipate or enslave us. Among the topics addressed are: Do Facebook and Google constitute "the greatest surveillance machine that ever existed," perpetually tracking our location, our contacts and our lives? Far from being victims of that surveillance, are most of us willing collaborators? Are there legitimate forms of surveillance, for instance in relation to the "Four Horsemen of the Infopocalypse" (money laundering, drugs, terrorism and pornography)? And do we have the ability, through conscious action and technological savvy, to resist this tide and secure a world where freedom is something which the Internet helps bring about?The harassment of WikiLeaks and other Internet activists, together with attempts to introduce anti-file sharing legislation such as SOPA and ACTA, indicate that the politics of the Internet have reached a crossroads. In one direction lies a future that guarantees, in the watchwords of the cypherpunks, "privacy for the weak and transparency for the powerful"; in the other lies an Internet that allows government and large corporations to discover ever more about internet users while hiding their own activities. Assange and his co-discussants unpick the complex issues surrounding this crucial choice with clarity and engaging enthusiasm.

    It is a brilliant and elegant exercise in model building that provides new insights into some of the old questions about philosophy of history, historical narrative, and what is called straight history."-Hayden White, University of California, Santa CruzWho were the first people to inhabit North America? Does the West Bank belong to the Arabs or the Jews? Why are racists so obsessed with origins? Is a seventh cousin still a cousin? Why do some societies name their children after dead ancestors?As Eviatar Zerubavel demonstrates in Time Maps, we cannot answer burning questions such as these without a deeper understanding of how we envision the past. In a pioneering attempt to map the structure of our collective memory, Zerubavel considers the cognitive patterns we use to organize the past in our minds and the mental strategies that help us string together unrelated events into coherent and meaningful narratives, as well as the social grammar of battles over conflicting interpretations of history. Drawing on fascinating examples that range from Hiroshima to the Holocaust, from Columbus to Lucy, and from ancient Egypt to the former Yugoslavia, Zerubavel shows how we construct historical origins; how we tie discontinuous events together into stories; how we link families and entire nations through genealogies; and how we separate distinct historical periods from one another through watersheds, such as the invention of fire or the fall of the Berlin Wall.Most people think the Roman Empire ended in 476, even though it lasted another 977 years in Byzantium. Challenging such conventional wisdom, Time Maps will be must reading for anyone interested in how the history of our world takes shape.

    One sought to discover a new planet. Another—an adventuresome female astronomer—fought to prove that science was not anathema to femininity. And a young, megalomaniacal inventor, with the tabloid press fast on his heels, sought to test his scientific bona fides and light the world through his revelations. David Baron brings to three-dimensional life these three competitors—James Craig Watson, Maria Mitchell, and Thomas Edison—and thrillingly re-creates the fierce jockeying of nineteenth-century American astronomy. With spellbinding accounts of train robberies and Indian skirmishes, the mythologized age of the last days of the Wild West comes alive as never before. A magnificent portrayal of America’s dawn as a scientific superpower, American Eclipse depicts a young nation that looked to the skies to reveal its towering ambition and expose its latent genius.

    This staggering amount of information—unprecedented in history—can tell us a great deal about who we are—the fears, desires, and behaviors that drive us, and the conscious and unconscious decisions we make. From the profound to the mundane, we can gain astonishing knowledge about the human psyche that less than twenty years ago, seemed unfathomable.Everybody Lies offers fascinating, surprising, and sometimes laugh-out-loud insights into everything from economics to ethics to sports to race to sex, gender and more, all drawn from the world of big data. What percentage of white voters didn’t vote for Barack Obama because he’s black? Does where you go to school effect how successful you are in life? Do parents secretly favor boy children over girls? Do violent films affect the crime rate? Can you beat the stock market? How regularly do we lie about our sex lives and who’s more self-conscious about sex, men or women?Investigating these questions and a host of others, Seth Stephens-Davidowitz offers revelations that can help us understand ourselves and our lives better. Drawing on studies and experiments on how we really live and think, he demonstrates in fascinating and often funny ways the extent to which all the world is indeed a lab. With conclusions ranging from strange-but-true to thought-provoking to disturbing, he explores the power of this digital truth serum and its deeper potential—revealing biases deeply embedded within us, information we can use to change our culture, and the questions we’re afraid to ask that might be essential to our health—both emotional and physical. All of us are touched by big data everyday, and its influence is multiplying. Everybody Lies challenges us to think differently about how we see it and the world.

    In The Enigma of Capital, he delivers an impassioned account of how unchecked neoliberalism produced the system-wide crisis that now engulfs the world. Beginning in the 1970s, profitability pressures led the capitalist class in advanced countries to shift away from investment in industrial production at home toward the higher returns that financial products promised. Accompanying this was a shift towards privatization, an absolute decline in the bargaining power of labor, and the dispersion of production throughout the developing world. The decades-long and ongoing decline in wages that accompanied this turn produced a dilemma: how can goods--especially real estate--sell at the same rate as before if workers are making less in relative terms? The answer was a huge expansion of credit that fueled the explosive growth of both the financial industry and the real estate market. When one key market collapsed--real estate--the other one did as well, and social devastation resulted. Harvey places today's crisis in the broadest possible context: the historical development of global capitalism itself from the industrial era onward. Moving deftly between this history and the unfolding of the current crisis, he concentrates on how such crises both devastate workers and create openings for challenging the system's legitimacy. The battle now will be between the still-powerful forces that want to reconstitute the system of yesterday and those that want to replace it with one that prizes social justice and economic equality. The new afterword focuses on the continuing impact of the crisis and the response to it in 2010. One of Huffington Post's Best Social and Political Awareness Books of 2010 Winner of the Isaac and Tamara Deutscher Memorial Prize for 2010 Praise for the Hardcover: "A lucid and penetrating account of how the power of capital shapes our world."--Andrew Gamble, Independent "Elegant... entertainingly swashbuckling... Harvey's analysis is interesting not only for the breadth of his scholarship but his recognition of the system's strengths."--John Gapper, Financial Times
