War in the Air 1914 45 Smithsonian History of Warfare
The first aircraft flew in 1903 and within ten years had been developed into military weapons.From World War I to World War II, pilots became exalted national heroes, gallant knights astride their iron steeds high above the skies of Europe. Far from the heroic fantasy, however, most pilots and aircrews struggled against grim odds, fighting out their frequently short lives with bravado and recklessness. This vivid account explores the conditions in which these pilots fought and the rise of air warfare to preeminence, culminating in the Enola Gay's fateful drop of the atomic bomb on Hiroshima. The early flying machines of World War I and the pilots who braved hostile skies The rise of airplane technology in the 1930s -- radar, blind-bombing devices, radio control, and the increased speed of new monoplane designs The contribution of Allied air power to the defeat of Nazi Germany, Raids on Japan, the drop of the atomic bomb on Hiroshima, and the beginning of a new era of warfare

From the author of 1491—the best-selling study of the pre-Columbian Americas—a deeply engaging new history of the most momentous biological event since the death of the dinosaurs. More than 200 million years ago, geological forces split apart the continents. Isolated from each other, the two halves of the world developed radically different suites of plants and animals. When Christopher Columbus set foot in the Americas, he ended that separation at a stroke. Driven by the economic goal of establishing trade with China, he accidentally set off an ecological convulsion as European vessels carried thousands of species to new homes across the oceans. The Columbian Exchange, as researchers call it, is the reason there are tomatoes in Italy, oranges in Florida, chocolates in Switzerland, and chili peppers in Thailand. More important, creatures the colonists knew nothing about hitched along for the ride. Earthworms, mosquitoes, and cockroaches; honeybees, dandelions, and African grasses; bacteria, fungi, and viruses; rats of every description—all of them rushed like eager tourists into lands that had never seen their like before, changing lives and landscapes across the planet. Eight decades after Columbus, a Spaniard named Legazpi succeeded where Columbus had failed. He sailed west to establish continual trade with China, then the richest, most powerful country in the world. In Manila, a city Legazpi founded, silver from the Americas, mined by African and Indian slaves, was sold to Asians in return for silk for Europeans. It was the first time that goods and people from every corner of the globe were connected in a single worldwide exchange. Much as Columbus created a new world biologically, Legazpi and the Spanish empire he served created a new world economically. As Charles C. Mann shows, the Columbian Exchange underlies much of subsequent human history. Presenting the latest research by ecologists, anthropologists, archaeologists, and historians, Mann shows how the creation of this worldwide network of ecological and economic exchange fostered the rise of Europe, devastated imperial China, convulsed Africa, and for two centuries made Mexico City—where Asia, Europe, and the new frontier of the Americas dynamically interacted—the center of the world. In such encounters, he uncovers the germ of today’s fiercest political disputes, from immigration to trade policy to culture wars. In 1493, Charles Mann gives us an eye-opening scientific interpretation of our past, unequaled in its authority and fascination. From the Hardcover edition.
People States Fear
The second edition of this widely acclaimed book takes as its main theme the question of how states and societies pursue freedom from threat in an environment in which competitive relations are inescapable across the political, economic, military, societal and environmental landscapes. Throughout, attention is placed on the interplay of threats and vulnerabilities, the policy consequences of overemphasizing one or the other, and the existence of contradictions within and between ideas about security. Barry Buzan argues that the concept of security is a versatile, penetrating and useful way to approach the study of international relations. Security provides an analytical framework which stands between the extremes of power and peace, incorporates most of their insights and adds more of its own.
Task Design In Mathematics Education
This book is the product of ICMI Study 22 Task Design in Mathematics Education. The study offers a state-of-the-art summary of relevant research and goes beyond that to develop new insights and new areas of knowledge and study about task design. The authors represent a wide range of countries and cultures and are leading researchers, teachers and designers. In particular, the authors develop explicit understandings of the opportunities and difficulties involved in designing and implementing tasks and of the interfaces between the teaching, researching and designing roles – recognising that these might be undertaken by the same person or by completely separate teams. Tasks generate the activity through which learners meet mathematical concepts, ideas, strategies and learn to use and develop mathematical thinking and modes of enquiry. Teaching includes the selection, modification, design, sequencing, installation, observation and evaluation of tasks. The book illustrates how task design is core to effective teaching, whether the task is a complex, extended, investigation or a small part of a lesson; whether it is part of a curriculum system, such as a textbook, or promotes free standing activity; whether the task comes from published source or is devised by the teacher or the student.
A World Destroyed

Thank God They re on Our Side
Despite its avowed commitment to liberalism and democracy internationally, the United States has frequently chosen to back repressive or authoritarian regimes in parts of the world. In this comprehensive examination of American support of right-wing dictatorships, David Schmitz challenges the contention that the democratic impulse has consistently motivated U.S. foreign policy. Compelled by a persistent concern for order and influenced by a paternalistic racism that characterized non-Western peoples as vulnerable to radical ideas, U.S. policymakers viewed authoritarian regimes as the only vehicles for maintaining political stability and encouraging economic growth in nations such as Nicaragua and Iran, Schmitz argues. Expediency overcame ideology, he says, and the United States gained useful_albeit brutal and corrupt_allies who supported American policies and provided a favorable atmosphere for U.S. trade. But such policy was not without its critics and did not remain static, Schmitz notes. Instead, its influence waxed and waned over the course of five decades, until the U.S. interventions in Vietnam marked its culmination.
"This book will introduce linguistics and tagmemics to undergraduates, graduate students, and scholars in linguistics, anthropology, and other social sciences. It explains the concerns of linguistics, locates linguistics in that much larger field of human behavior that other disciplines share, and presents language from a vantage that acknowledges their particular concerns." -- Back cover.
