Humankind has been faced with many diseases in the past. Some like the Bubonic Plague during the Middle Ages which killed one third of humans on the planet. In the 20. An intersectional history of the shared struggle for African American and Latinx civil rightsSpanning more than two hundred years, An African American and Latinx History of the United States is a revolutionary, politically charged narrative history, arguing that the Global South was crucial to the development of America as we know it. Scholar and activist Paul Ortiz challenges the notion of westward progress as exalted by widely taught formulations like manifest destiny and Jacksonian democracy, and shows how placing African American, Latinx, and Indigenous voices unapologetically front and center transforms US history into one of the working class organizing against imperialism.Drawing on rich narratives and primary source documents, Ortiz links racial segregation in the Southwest and the rise and violent fall of a powerful tradition of Mexican labor organizing in the twentieth century, to May 1, 2006, known as International Workers\' Day, when migrant laborers--Chicana/os, Afrocubanos, and immigrants from every continent on earth--united in resistance on the first Day Without Immigrants. As African American civil rights activists fought Jim Crow laws and Mexican labor organizers warred against the suffocating grip of capitalism, Black and Spanish-language newspapers, abolitionists, and Latin American revolutionaries coalesced around movements built between people from the United States and people from Central America and the Caribbean. In stark contrast to the resurgence of America First rhetoric, Black and Latinx intellectuals and organizers today have historically urged the United States to build bridges of solidarity with the nations of the Americas.Incisive and timely, this bottom-up history, told from the interconnected vantage points of Latinx and African Americans, reveals the radically different ways that people of the diaspora have addressed issues still plaguing the United States today, and it offers a way forward in the continued struggle for universal civil rights.2018 Winner of the PEN Oakland/Josephine Miles Literary Award The International Space Station (ISS) is the largest man-made structure to orbit Earth and has been conducting research for close to a decade and a half. Yet it is only the latest in a long line of space stations and laboratories that have flown in orbit since the early 1970s. The histories of these earlier programs have been all but forgotten as the public focused on other, higher-profile adventures such as the Apollo moon landings.A vast trove of stories filled with excitement, danger, humor, sadness, failure, and success, Outposts on the Frontier reveals how the Soviets and the Americans combined strengths to build space stations over the past fifty years. At the heart of these scientific advances are people of both greatness and modesty. Jay Chladek documents the historical tapestry of the people, the early attempts at space station programs, and how astronauts and engineers have contributed to and shaped the ISS in surprising ways. Outposts on the Frontier delves into the intriguing stories behind the USAF Manned Orbiting Laboratory, the Almaz and Salyut programs, Skylab, the Apollo–Soyuz Test Project, Spacelab, Mir station, Spacehab, and the ISS, and gives past-due attention to Vladimir Chelomei, the Russian designer whose influence in space station development is as significant as Sergei Korolev’s in rocketry.Outposts on the Frontier is an informative and dynamic history of humankind’s first outposts on the frontier of space. The evolution of a discipline at the intersection of physics, chemistry, and mathematics.Quantum chemistry--a discipline that is not quite physics, not quite chemistry, and not quite applied mathematics--emerged as a field of study in the 1920s. It was referred to by such terms as mathematical chemistry, subatomic theoretical chemistry, molecular quantum mechanics, and chemical physics until the community agreed on the designation of quantum chemistry. In Neither Physics Nor Chemistry, Kostas Gavroglu and Ana Simoes examine the evolution of quantum chemistry into an autonomous discipline, tracing its development from the publication of early papers in the 1920s to the dramatic changes brought about by the use of computers in the 1970s.The authors focus on the culture that emerged from the creative synthesis of the various traditions of chemistry, physics, and mathematics. They examine the concepts, practices, languages, and institutions of this new culture as well as the people who established it, from such pioneers as Walter Heitler and Fritz London, Linus Pauling, and Robert Sanderson Mulliken, to later figures including Charles Alfred Coulson, Raymond Daudel, and Per-Olov Lowdin. Throughout, the authors emphasize six themes: epistemic aspects and the dilemmas caused by multiple approaches social issues, including academic politics, the impact of textbooks, and the forging of alliances the contingencies that arose at every stage of the developments in quantum chemistry the changes in the field when computers were available to perform the extraordinarily cumbersome calculations required issues in the philosophy of science and different styles of reasoning. The free and open source software movement, from its origins in hacker culture, through the development of GNU and Linux, to its commercial use today.In the 1980s, there was a revolution with far-reaching consequences--a revolution to restore software freedom. In the early 1980s, after decades of making source code available with programs, most programmers ceased sharing code freely. A band of revolutionaries, self-described hackers, challenged this new norm by building operating systems with source code that could be freely shared. In For Fun and Profit, Christopher Tozzi offers an account of the free and open source software (FOSS) revolution, from its origins as an obscure, marginal effort by a small group of programmers to the widespread commercial use of open source software today. Tozzi explains FOSS\'s historical trajectory, shaped by eccentric personalities--including Richard Stallman and Linus Torvalds--and driven both by ideology and pragmatism, by fun and profit.Tozzi examines hacker culture and its influence on the Unix operating system, the reaction to Unix\'s commercialization, and the history of early Linux development. He describes the commercial boom that followed, when companies invested billions of dollars in products using FOSS operating systems the subsequent tensions within the FOSS movement and the battles with closed source software companies (especially Microsoft) that saw FOSS as a threat. Finally, Tozzi describes FOSS\'s current dominance in embedded computing, mobile devices, and the cloud, as well as its cultural and intellectual influence. With hundreds of full-colour photographs and fascinating ephemera, combined with an authoritative text listing hundreds of chainsaw models from the 1800s to the present, Chainsaws carefully traces the evolutionary threads of countless pioneer devices--from six-hundred-pound steam-powered behemoths, to gas chainsaws mounted on wheeled carriages, to diesel chainsaws. The meticulous text examines Andreas Stihl\'s Black Forest experiments, Vancouver\'s booming WWII chainsaw industry and the postwar race to develop one-man saws, the rise and fall of Canada\'s proud Pioneer brand, and the late entry into the field of the centuries-old arms manufacturer Husqvarna. Recalling once-familiar brands such as Titan, Timberhog, Bluestreak, Hi-Baller, Hornet, Wasp, IEL, Partner, PM, Poulan, Dolmar, Danarm, Disston, Remington, Canadien, Lombard, Mall, McCulloch, Shade, Solo, Be-Bo and Jo-Bu among others, author David Lee worked together with some of the world\'s leading chainsaw history experts to create this tribute to one of humanity\'s most labour-saving inventions.Lee concludes this new paperback edition with a note on recent advances in chainsaw technology--notably the cordless electric chainsaw, powered by a lithium-ion battery--bringing readers up to date on today\'s lightweight modern machine. Chainsaws is a handsome gift book and an indispensable reference for anybody with an interest in chainsaws or technology. This new book presents over seven years of research into the history of the M-1 helmet during World War II, and provides the most comprehensive examination of its development and production. All aspects of M-1 helmet production are covered including: the helmet body, the fiber liner, the plastic liner, the parachutist helmet, helmet camouflage, helmet modifications, helmet paint schemes, and toy helmets. Every production helmet version is presented in full color photographs, including detail shots and production markings. Also included are World War II era photographs of the helmet samples, helmet production, and helmets worn in training or in action. This book a valuable reference to both historians and collectors. \"A New York Times-bestselling author explains how the physical world shaped the history of our species

When we talk about human history, we often focus on great leaders, population forces, and decisive wars. But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the south-east United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea. Everywhere is the deep imprint of the planetary on the human. From the cultivation of the first crops to the founding of modern states, Origins reveals the breathtaking impact of the earth beneath our feet on the shape of our human civilizations.\" What is environmental history? It is a kind of history that seeks understanding of human beings as they have lived, worked, and thought in relationship to the rest of nature through the changes brought by time. In this new edition of his seminal student textbook, J. Donald Hughes provides a masterful overview of the thinkers, topics, and perspectives that have come to constitute the exciting discipline that is environmental history. He does so on a global scale, drawing together disparate trends from a rich variety of countries into a unified whole, illuminating trends and key themes in the process. Those already familiar with the discipline will find themselves invited to think about the subject in a new way. This new edition has been updated to reflect recent developments, trends, and new work in environmental history, as well as a brand new note on its possible future. Students and scholars new to environmental history will find the book both an indispensable guide and a rich source of inspiration for future work.
