Polya, How to Solve It will show anyone in any field how to think straight. In lucid and appealing prose, Polya reveals how the mathematical method of demonstrating a proof or finding an unknown can be of help in attacking any problem that can be reasoned out--from building a bridge to winning a game of anagrams. Generations of readers have relished Polya's deft--indeed, brilliant--instructions on stripping away irrelevancies and going straight to the heart of the problem.

    Combining firsthand accounts of employees' escapes with an in-depth look at the structural reasons behind the towers' collapse, Chiles addresses the question, Were the towers "two tall heroes" or structures with a fatal flaw?

    Gordon strips engineering of its confusing technical terms, communicating its founding principles in accessible, witty prose.For anyone who has ever wondered why suspension bridges don't collapse under eight lanes of traffic, how dams hold back--or give way under--thousands of gallons of water, or what principles guide the design of a skyscraper, a bias-cut dress, or a kangaroo, this book will ease your anxiety and answer your questions.Structures: Or Why Things Don't Fall Down is an informal explanation of the basic forces that hold together the ordinary and essential things of this world--from buildings and bodies to flying aircraft and eggshells. In a style that combines wit, a masterful command of his subject, and an encyclopedic range of reference, Gordon includes such chapters as "How to Design a Worm" and "The Advantage of Being a Beam," offering humorous insights in human and natural creation.Architects and engineers will appreciate the clear and cogent explanations of the concepts of stress, shear, torsion, fracture, and compression. If you're building a house, a sailboat, or a catapult, here is a handy tool for understanding the mechanics of joinery, floors, ceilings, hulls, masts--or flying buttresses.Without jargon or oversimplification, Structures opens up the marvels of technology to anyone interested in the foundations of our everyday lives.

    While I don't share his conclusions about the potential for social movements to drive ambitious mitigation, this is a wise and important challenge from an elegant writer and original thinker. A critical intervention."--Naomi Klein, author of This Changes Everything: Capitalism vs. the ClimateComing home from the war in Iraq, US Army private Roy Scranton thought he'd left the world of strife behind. Then he watched as new calamities struck America, heralding a threat far more dangerous than ISIS or Al Qaeda: Hurricane Katrina, Superstorm Sandy, megadrought--the shock and awe of global warming.Our world is changing. Rising seas, spiking temperatures, and extreme weather imperil global infrastructure, crops, and water supplies. Conflict, famine, plagues, and riots menace from every quarter. From war-stricken Baghdad to the melting Arctic, human-caused climate change poses a danger not only to political and economic stability, but to civilization itself . . . and to what it means to be human. Our greatest enemy, it turns out, is ourselves. The warmer, wetter, more chaotic world we now live in--the Anthropocene--demands a radical new vision of human life.In this bracing response to climate change, Roy Scranton combines memoir, reportage, philosophy, and Zen wisdom to explore what it means to be human in a rapidly evolving world, taking readers on a journey through street protests, the latest findings of earth scientists, a historic UN summit, millennia of geological history, and the persistent vitality of ancient literature. Expanding on his influential New York Times essay (the #1 most-emailed article the day it appeared, and selected for Best American Science and Nature Writing 2014), Scranton responds to the existential problem of global warming by arguing that in order to survive, we must come to terms with death.Plato argued that to philosophize is to learn to die. If that’s true, says Scranton, then we have entered humanity’s most philosophical age—or this is precisely the problem of the Anthropocene. The trouble now is that we must learn to die not as individuals, but as a civilization.A war veteran, journalist, author, and Princeton PhD candidate, Roy Scranton has published in the New York Times, Wall Street Journal, Rolling Stone, Boston Review, and Theory and Event, and has been interviewed on NPR's Fresh Air, among other media.More praise for Learning to Die in the Anthropocene:"Perhaps it is because he is a soldier, perhaps it is because he is a literate human being, but the fact is--Roy Scranton gets it. He knows in his bones that this civilization is over. He knows it is high time to start again the human dance of making some other way to live. In his distinctive and original way he works though a common cultural inheritance, making it something fresh and new for these all too interesting times. This compressed, essential text offers both uncomfortable truths and unexpected joy."--McKenzie Wark, author of Molecular Red: Theory for the Anthropocene

    Adopting those aspects of the religion that suited his purposes, he turned Rome on a course from the relatively open, tolerant and pluralistic civilization of the Hellenistic world, towards a culture that was based on the rule of fixed authority, whether that of the Bible, or the writings of Ptolemy in astronomy and of Galen and Hippocrates in medicine. Only a thousand years later, with the advent of the Renaissance and the emergence of modern science, did Europe begin to free itself from the effects of Constantine's decision, yet the effects of his establishment of Christianity as a state religion remain with us, in many respects, today. Brilliantly wide-ranging and ambitious, this is a major work of history.

    Eric Weitz has written the authoritative history that this fascinating and complex period deserves, and he illuminates the uniquely progressive achievements and even greater promise of the Weimar Republic. Weitz reveals how Germans rose from the turbulence and defeat of World War I and revolution to forge democratic institutions and make Berlin a world capital of avant-garde art. He explores the period’s groundbreaking cultural creativity, from architecture and theater, to the new field of "sexology"—and presents richly detailed portraits of some of the Weimar’s greatest figures. Weimar Germany also shows that beneath this glossy veneer lay political turmoil that ultimately led to the demise of the republic and the rise of the radical Right. Yet for decades after, the Weimar period continued to powerfully influence contemporary art, urban design, and intellectual life—from Tokyo to Ankara, and Brasilia to New York. Featuring a new preface, this comprehensive and compelling book demonstrates why Weimar is an example of all that is liberating and all that can go wrong in a democracy.

    But archaeological and historical evidence challenges this narrative. The first agrarian states, says James C. Scott, were born of accumulations of domestications: first fire, then plants, livestock, subjects of the state, captives, and finally women in the patriarchal family—all of which can be viewed as a way of gaining control over reproduction.   Scott explores why we avoided sedentism and plow agriculture, the advantages of mobile subsistence, the unforeseeable disease epidemics arising from crowding plants, animals, and grain, and why all early states are based on millets and cereal grains and unfree labor. He also discusses the “barbarians” who long evaded state control, as a way of understanding continuing tension between states and nonsubject peoples.

    As the 3rd Reich embarked upon its plan of conquest & genocide, IBM & its subsidiaries helped create enabling technologies, step-by-step, from the identification & cataloging programs of the 30s to the selections of the 40s. Only after Jews were identified--a massively complex task Hitler wanted done immediately--could they be targeted for efficient asset confiscation, ghettoization, deportation, enslaved labor & annihilation. It was a cross-tabulation & organizational challenge so monumental, it called for a computer. Of course, in the 30s no computer existed. But IBM's Hollerith punch card technology did exist. Aided by the company's custom-designed & constantly updated Hollerith systems, Hitler was able to automate the persecution of the Jews.Historians were amazed at the speed & accuracy with which the Nazis were able to identify & locate European Jewry. Until now, the pieces of this puzzle have never been fully assembled. The fact is, IBM technology was used to organize nearly everything in Germany & then Nazi Europe, from the identification of the Jews in censuses, registrations & ancestral tracing programs to the running of railroads & organizing of concentration camp slave labor. IBM & its German subsidiary custom-designed complex solutions, anticipating the Reich's needs. They didn't merely sell the machines & walk away. Instead, IBM leased these machines for high fees & became the sole source of the billions of punch cards needed. IBM & the Holocaust details the carefully crafted corporate collusion with the 3rd Reich, as well as the structured deniability of oral agreements, undated letters & the Geneva intermediaries--all undertaken as the newspapers blazed with accounts of persecution & destruction. Just as compelling is the human drama of one of our century's greatest minds, IBM founder Thomas Watson, who cooperated with the Nazis for the sake of profit. Only with IBM's technologic assistance was Hitler able to achieve the staggering numbers of the Holocaust. Edwin Black has now uncovered one of the last great mysteries of Germany's war against the Jews: how Hitler got the names.

    Corporations & government agencies around the world are pouring billions into achieving AI’s Holy Grail—human-level intelligence. Once AI has attained it, scientists argue, it will have survival drives much like our own. We may be forced to compete with a rival more cunning, more powerful & more alien than we can imagine. Thru profiles of tech visionaries, industry watchdogs & groundbreaking AI systems, James Barrat's Our Final Invention explores the perils of the heedless pursuit of advanced AI. Until now, human intelligence has had no rival. Can we coexist with beings whose intelligence dwarfs our own? Will they allow us to?

    After 3.8 billion years humankind is about to start evolving by new rules...From leading geopolitical expert and technology futurist Jamie Metzl comes a groundbreaking exploration of the many ways genetic-engineering is shaking the core foundations of our lives -- sex, war, love, and death.At the dawn of the genetics revolution, our DNA is becoming as readable, writable, and hackable as our information technology. But as humanity starts retooling our own genetic code, the choices we make today will be the difference between realizing breathtaking advances in human well-being and descending into a dangerous and potentially deadly genetic arms race.Enter the laboratories where scientists are turning science fiction into reality. Look towards a future where our deepest beliefs, morals, religions, and politics are challenged like never before and the very essence of what it means to be human is at play. When we can engineer our future children, massively extend our lifespans, build life from scratch, and recreate the plant and animal world, should we?

    And two giants at the foundations of modern science were converging, step-by-step, on the answer: Albert Einstein, an young, obscure German physicist experimenting with measuring time using telegraph networks and with the coordination of clocks at train stations; and the renowned mathematician Henri Poincaré, president of the French Bureau of Longitude, mapping time coordinates across continents. Each found that to understand the newly global world, he had to determine whether there existed a pure time in which simultaneity was absolute or whether time was relative.Esteemed historian of science Peter Galison has culled new information from rarely seen photographs, forgotten patents, and unexplored archives to tell the fascinating story of two scientists whose concrete, professional preoccupations engaged them in a silent race toward a theory that would conquer the empire of time.

    Indeed, he sees the fall of Rome as a time of horror and dislocation that destroyed a great civilization, throwing the inhabitants of the West back to a standard of living typical of prehistoric times. Attacking contemporary theories with relish and making use of modern archaeological evidence, he looks at both the wider explanations for the disintegration of the Roman world and also the consequences for the lives of everyday Romans, who were caught in a world of marauding barbarians, and economic collapse.The book recaptures the drama and violence of the last days of the Roman world, and reminds us of the very real terrors of barbarian occupation. Equally important, Ward-Perkins contends that a key problem with the new way of looking at the end of the ancient world is that all difficulty and awkwardness is smoothed out into a steady and positive transformation of society. Nothing ever goes badly wrong in this vision of the past. The evidence shows otherwise.Up-to-date and brilliantly written, combining a lively narrative with the latest research and thirty illustrations, this superb volume reclaims the drama, the violence, and the tragedy of the fall of Rome.From Back Cover:For decades, the dominant view amongst historians has been that the 'fall of Rome' was a largely peaceful transition to Germanic rule, within a period of positive cultural evolution. Now, Bryan Ward-Perkins argues for what you always thought but didn't dare say: the Roman Empire really did fall to violent invasion; the 'transformation' of the Roman world saw a catastrophic collapse of living standards; and the 'Dark Ages' were genuinely sombre.
