Sit back and enjoy a collection of verbatim exchanges from the halls of justice, where defendants and plaintiffs, lawyers and witnesses, juries and judges, collide to produce memorably insane comedy. The Court: "The charge here is theft of frozen chickens. Are you the defendant, sir?" Defendant: "No, sir, I'm the guy who stole the chickens."

A groundbreaking examination of the growing inequality gap from the bestselling author of Bowling Alone: why fewer Americans today have the opportunity for upward mobility. It’s the American dream: get a good education, work hard, buy a house, and achieve prosperity and success. This is the America we believe in—a nation of opportunity, constrained only by ability and effort. But during the last twenty-five years we have seen a disturbing “opportunity gap” emerge. Americans have always believed in equality of opportunity, the idea that all kids, regardless of their family background, should have a decent chance to improve their lot in life. Now, this central tenet of the American dream seems no longer true or at the least, much less true than it was. Robert Putnam—about whom The Economist said, “his scholarship is wide-ranging, his intelligence luminous, his tone modest, his prose unpretentious and frequently funny”—offers a personal but also authoritative look at this new American crisis. Putnam begins with his high school class of 1959 in Port Clinton, Ohio. By and large the vast majority of those students—“our kids”—went on to lives better than those of their parents. But their children and grandchildren have had harder lives amid diminishing prospects. Putnam tells the tale of lessening opportunity through poignant life stories of rich and poor kids from cities and suburbs across the country, drawing on a formidable body of research done especially for this book. Our Kids is a rare combination of individual testimony and rigorous evidence. Putnam provides a disturbing account of the American dream that should initiate a deep examination of the future of our country.

本书最为难能可贵的是始终贯穿着强烈的应用意识，即把数学理论紧密地与政治、经济、体育、艺术、医学、生物、科技、环境等实际问题相结合，这在国内外数学教科书中是不多见的。本书内容包括集合论、数理逻辑、图论、运筹、统计、概率、排列组合、代数、几何和矩阵等。书中每一章的开始提出实际问题，然后发展必要的数学工具，解决问题，从而在应用中进一步加强对数学的理解。讨论的问题涉及日常生活，如信用卡购物、年利率计算、运动队成绩的评价等；也有著名的数学问题，如四色问题等；还有数学在高新技术中的应用。众多的应用问题使本书变得趣味横生。 　　本书主要可作为非理工类专业师生的教科书，也可作为理工类师生、工程技术人员、管理人员的参考书。

We know that power is shifting: From West to East and North to South, from presidential palaces to public squares, from once formidable corporate behemoths to nimble startups and, slowly but surely, from men to women. But power is not merely shifting and dispersing. It is also decaying. Those in power today are more constrained in what they can do with it and more at risk of losing it than ever before. In "The End of Power," award-winning columnist and former "Foreign Policy" editor Moises Naim illuminates the struggle between once-dominant megaplayers and the new micropowers challenging them in every field of human endeavor. Drawing on provocative, original research, Naim shows how the antiestablishment drive of micropowers can topple tyrants, dislodge monopolies, and open remarkable new opportunities, but it can also lead to chaos and paralysis. Naim deftly covers the seismic changes underway in business, religion, education, within families, and in all matters of war and peace. Examples abound in all walks of life: In 1977, eighty-nine countries were ruled by autocrats while today more than half the world's population lives in democracies. CEO's are more constrained and have shorter tenures than their predecessors. Modern tools of war, cheaper and more accessible, make it possible for groups like Hezbollah to afford their own drones. In the second half of 2010, the top ten hedge funds earned more than the world's largest six banks combined. Those in power retain it by erecting powerful barriers to keep challengers at bay. Today, insurgent forces dismantle those barriers more quickly and easily than ever, only to find that they themselves become vulnerable in the process. Accessible and captivating, Naim offers a revolutionary look at the inevitable end of power--and how it will change your world.
