A century ago, the telegraph and the mechanical tabulator were used to tame cities of millions. Today, cellular networks and cloud computing tie together the complex choreography of mega-regions of tens of millions of people.In response, cities worldwide are deploying technology to address both the timeless challenges of government and the mounting problems posed by human settlements of previously unimaginable size and complexity. In Chicago, GPS sensors on snow plows feed a real-time "plow tracker" map that everyone can access. In Zaragoza, Spain, a "citizen card" can get you on the free city-wide Wi-Fi network, unlock a bike share, check a book out of the library, and pay for your bus ride home. In New York, a guerrilla group of citizen-scientists installed sensors in local sewers to alert you when stormwater runoff overwhelms the system, dumping waste into local waterways.As technology barons, entrepreneurs, mayors, and an emerging vanguard of civic hackers are trying to shape this new frontier, Smart Cities considers the motivations, aspirations, and shortcomings of them all while offering a new civics to guide our efforts as we build the future together, one click at a time.

    These are the very same behaviors that typify good soldiering and foster a sense of belonging among troops, whether they’re fighting on the front lines or engaged in non-combat activities away from the action. Drawing from history, psychology, and anthropology, bestselling author Sebastian Junger shows us just how at odds the structure of modern society is with our tribal instincts, arguing that the difficulties many veterans face upon returning home from war do not stem entirely from the trauma they’ve suffered, but also from the individualist societies they must reintegrate into.A 2011 study by the Canadian Forces and Statistics Canada reveals that 78 percent of military suicides from 1972 to the end of 2006 involved veterans. Though these numbers present an implicit call to action, the government is only just taking steps now to address the problems veterans face when they return home. But can the government ever truly eliminate the challenges faced by returning veterans? Or is the problem deeper, woven into the very fabric of our modern existence? Perhaps our circumstances are not so bleak, and simply understanding that beneath our modern guises we all belong to one tribe or another would help us face not just the problems of our nation but of our individual lives as well.Well-researched and compellingly written, this timely look at how veterans react to coming home will reconceive our approach to veteran’s affairs and help us to repair our current social dynamic.

They also consider the impact on jobs, and how we can prepare for the opportunities, as well as the dangers, that await.Thought-provoking, engaging and full of insight from the forefront of tech innovation, Megatech is essential reading for anyone who wants to understand tomorrow's world.

    Turchin argues that the key to the formation of an empire is a society’s capacity for collective action. He demonstrates that high levels of cooperation are found where people have to band together to fight off a common enemy, and that this kind of cooperation led to the formation of the Roman and Russian empires, and the United States. But as empires grow, the rich get richer and the poor get poorer, conflict replaces cooperation, and dissolution inevitably follows. Eloquently argued and rich with historical examples, War and Peace and War offers a bold new theory about the course of world history.

    These are the headlines of history, but they cannot be properly grasped without understanding the role that population has played.The Human Tide shows how periods of rapid population transition -- a phenomenon that first emerged in the British Isles but gradually spread across the globe--shaped the course of world history. Demography -- the study of population -- is the key to unlocking an understanding of the world we live in and how we got here. Demographic changes explain why the Arab Spring came and went, how China rose so meteorically, and why Britain voted for Brexit and America for Donald Trump. Sweeping from Europe to the Americas, China, East Asia, the Middle East, and North Africa, The Human Tide is a panoramic view of the sheer power of numbers.
