    Within democracies, although 'strong leaders' are seldom as strong or independent as they purport to be, the idea that one person is entitled to take the big decisions is dangerous nonetheless, and the advantages of a collegial style of leadership are too often overlooked.In reality, only a minority of political leaders make a big difference, by challenging assumptions about the politically possible or setting in motion systemic change. Yet in a democracy that is rare. It is especially when enlightened leaders acquire power in an authoritarian system that the opportunity for radical transformation occurs.Franklin D. Roosevelt and Lyndon B. Johnson, Willy Brandt and Mikhail Gorbachev, Deng Xiaoping and Nelson Mandela, Margaret Thatcher and Tony Blair are among the leaders whom Brown examines in this original and illuminating study.

    In Elephants on Acid, Boese details the results of this scientific trial, as well as answers to the questions: Why can't people tickle themselves? Would the average dog summon help in an emergency? Will babies instinctually pick a well-balanced diet? Is it possible to restore life to the dead? Read on to find out...

    This history reaches far back to the earliest civilisation in the Americas, and it was the Olmecs not the Aztecs who can be rightly named as the inventors of chocolate. Told with flair and wit, this history of cacoa looks at its ancient Mexican roots, questioning how it became the food of the gods, its ritual significance, and how it was used as a currency in trade among the Olmec. Piecing together a range of archaeological, documentary and pictorial evidence, Sophie and Michael Coe discuss the Theobrama cacoa tree, the chemical properties of cacao and its early domestication and use. The story of chocolate continues under the Aztecs and their first encounters with the Europeans. The authors trace the transformation and renaming of cacao as it made its way to the chocoholics of Europe - the white-skinned perfumed, bewigged, overdressed royalty and nobility'. Finally, Coe and Coe discuss its years of competititon with tea and coffee as the preferred hot beverage, its links with the Church, and its surrender to the industrialisation of the 19th century which withdrew the mystique of this luscious mouth-watering treat and turned it into an everyday, mass-produced, highly calorific product.

    Here and there, we can supplement these meager scraps by the use of biochemical markers or geochemical signatures that add useful information, but, even with such additional help, our reconstructions and our models of descent are often tentative. For the fossil record is, as we have seen, as biased as it is incomplete. But fragmentary, selective, and biased though it is, the fossil record, with all its imperfections, is still a treasure. Though whole chapters are missing, many pages lost, and the earliest pages so damaged as to be, as yet, virtually unreadable, this--the greatest biography of all--is one in whose closing pages we find ourselves.--from OriginsIn Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.Rhodes's accessible and extensively illustrated treatment of the origins narrative describes the nature of the search for prehistoric life, the significance of geologic time, the origin of life, the emergence and spread of flora and fauna, the evolution of primates, and the emergence of modern humans.

    What does this unavoidable fact mean?For future generations, it won't mean anything very obvious. They will be so immersed in online life that questions about the Internet's basic purpose or meaning will vanish.But those of us who have lived both with and without the crowded connectivity of online life have a rare opportunity. We can still recognize the difference between Before and After. We catch ourselves idly reaching for our phones at the bus stop. Or we notice how, mid-conversation, a fumbling friend dives into the perfect recall of Google.In this eloquent and thought-provoking book, Michael Harris argues that amid all the changes we're experiencing, the most interesting is the one that future generations will find hardest to grasp. That is the end of absence-the loss of lack. The daydreaming silences in our lives are filled; the burning solitudes are extinguished. There's no true "free time" when you carry a smartphone. Today's rarest commodity is the chance to be alone with your own thoughts.

    There she saw first-hand how deeply intertwined Silicon Valley was with the federal government, and always had been, and how shallow the common understanding of the secrets of the Valley's success actually was. Now, after almost five years of pioneering research, O'Mara has produced the definitive history of Silicon Valley for our time, the story of mavericks and visionaries, but also of powerful institutions creating the framework for innovation, from the Pentagon to Stanford University. It is also a story of a community that started off remarkably homogeneous and elitist and stayed that way, and whose belief in its own mythology has deepened into a collective hubris that has led to astonishing triumphs as well as devastating second-order effects.Deploying a wonderfully rich and diverse cast of protagonists, from the justly famous to the unjustly obscure, across four generations of explosive growth in the Valley, from the Forties to the present, O'Mara has wrestled into magnificent narrative form one of the most fateful developments in modern American history. She is on the ground with all of the key tech companies, and chronicles the evolution in their offerings through each successive era, and she has a profound fingertip feel for the politics of the sector, and its relation to the larger cultural narrative about tech as it has evolved over the years. Perhaps most impressively, O'Mara has penetrated the inner kingdom of tech venture capital firms, the insular and still remarkably old-boy world that became the cockpit of American capitalism and the crucible for bringing technological innovation to market, or not. The transformation of big tech into the engine room of the American economy and the nexus of so many of our hopes and dreams--and increasingly nightmares--can be understood, in Margaret O'Mara's masterful hands, as the story of one California valley. As her majestic history makes clear, its fate is the fate of us all.

    Particularly noteworthy are the numerous historical examples of past efforts to make sense of complex systems of information. In this new companion volume, The Book of Trees, data viz expert Manuel Lima examines the more than eight hundred year history of the tree diagram, from its roots in the illuminated manuscripts of medieval monasteries to its current resurgence as an elegant means of visualization. Lima presents two hundred intricately detailed tree diagram illustrations on a remarkable variety of subjects—from some of the earliest known examples from ancient Mesopotamia to the manuscripts of medieval monasteries to contributions by leading contemporary designers. A timeline of capsule biographies on key figures in the development of the tree diagram rounds out this one-of-a-kind visual compendium.

    Their choices are limited by mountains, rivers, seas, and concrete. To understand world events, news organizations and other authorities often focus on people, ideas, and political movements, but without geography, we never have the full picture. Now, in the relevant and timely Prisoners of Geography, seasoned journalist Tim Marshall examines Russia, China, the USA, Latin America, the Middle East, Africa, Europe, Japan and Korea, and Greenland and the Arctic—their weather, seas, mountains, rivers, deserts, and borders—to provide a context often missing from our political reportage: how the physical characteristics of these countries affect their strengths and vulnerabilities and the decisions made by their leaders.In ten, up-to-date maps of each region, Marshall explains in clear and engaging prose the complex geo-political strategies of these key parts of the globe. What does it mean that Russia must have a navy, but also has frozen ports six months a year? How does this affect Putin’s treatment of Ukraine? How is China’s future constrained by its geography? Why will Europe never be united? Why will America never be invaded? Shining a light on the unavoidable physical realities that shape all of our aspirations and endeavors, Prisoners of Geography is the critical guide to one of the major (and most often overlooked) determining factors in world history.

    No one can stop him--but he walks away. A miracle? No...dysentery. Microbes saved the Roman Empire. Nearly a millennium later, the microbes of the Black Death ended the Middle Ages, making possible the Renaissance, western democracy, and the scientific revolution. Soon after, microbes ravaged the Americas, paving the way for their European conquest. Again and again, microbes have shaped our health, our genetics, our history, our culture, our politics, even our religion and ethics. This book reveals much that scientists and cultural historians have learned about the pervasive interconnections between infectious microbes and humans. It also considers what our ongoing fundamental relationship with infectious microbes might mean for the future of the human species. The "good side" of history's worst epidemics The surprising debt we owe to killer diseases Where diseases came from... ...and where they may be going Children of pestilence: disease and civilization From Egypt to Mexico, the Romans to Attila the Hun STDs, sexual behavior, and culture How microbes may shape cultural cycles of puritanism and promiscuity

    Charles Darwin's theory of evolution turned the Victorian world upside down, utterly rewrote our notions of life on earth, and is still attacked by religious creationists today.

    Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species - these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The "Anthropocene," as the proposed new epoch has been named, is regularly in the news.Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world, kindling intense debates. The reason is clear. The Anthropocene represents far more than just another interval of geologic time. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised.This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: The nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? Erle Ellis considers the many ways that the Anthropocene's "evolving paradigm" is reshaping the sciences, stimulating the humanities, and foregrounding the politics of life on a planet transformed by humans. The Anthropocene remains a work in progress. Is this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption? Ellis offers an insightful discussion of our role in shaping the planet, and how this will influence our future on many fronts.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

    From the world’s most painful hornet, to the flies that transmit deadly diseases, to millipedes that stop traffic, to the “bookworms” that devour libraries, to the Japanese beetles munching on your roses, Wicked Bugs delves into the extraordinary powers of many-legged creatures. With wit, style, and exacting research, Stewart has uncovered the most terrifying and titillating stories of bugs gone wild. It’s an A to Z of insect enemies, interspersed with sections that explore bugs with kinky sex lives (“She’s Just Not That Into You”), creatures lurking in the cupboard (“Fear No Weevil”), insects eating your tomatoes (“Gardener’s Dirty Dozen”), and phobias that feed our (sometimes) irrational responses to bugs (“Have No Fear”). Intricate and strangely beautiful etchings and drawings by Briony Morrow-Cribbs capture diabolical bugs of all shapes and sizes in this mixture of history, science, murder, and intrigue that begins—but doesn’t end—in your own backyard.

    Mountains of print have been written about culture. Loonshots identifies the small shifts in structure that control this transition, the same way that temperature controls the change from water to ice.Using examples that range from the spread of fires in forests to the hunt for terrorists online, and stories of thieves and geniuses and kings, Bahcall shows how this new kind of science helps us understand the behavior of companies and the fate of empires. Loonshots distills these insights into lessons for creatives, entrepreneurs, and visionaries everywhere.
