Download or read book Reaganland written by Rick Perlstein and published by Simon & Schuster. This book was released on 2020-08-18 with total page 1120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NEW YORK TIMES NOTABLE BOOK OF 2020 From the bestselling author of Nixonland and The Invisible Bridge comes the dramatic conclusion of how conservatism took control of American political power. Over two decades, Rick Perlstein has published three definitive works about the emerging dominance of conservatism in modern American politics. With the saga’s final installment, he has delivered yet another stunning literary and historical achievement. In late 1976, Ronald Reagan was dismissed as a man without a political future: defeated in his nomination bid against a sitting president of his own party, blamed for President Gerald Ford’s defeat, too old to make another run. His comeback was fueled by an extraordinary confluence: fundamentalist preachers and former segregationists reinventing themselves as militant crusaders against gay rights and feminism; business executives uniting against regulation in an era of economic decline; a cadre of secretive “New Right” organizers deploying state-of-the-art technology, bending political norms to the breaking point—and Reagan’s own unbending optimism, his ability to convey unshakable confidence in America as the world’s “shining city on a hill.” Meanwhile, a civil war broke out in the Democratic party. When President Jimmy Carter called Americans to a new ethic of austerity, Senator Ted Kennedy reacted with horror, challenging him for reelection. Carter’s Oval Office tenure was further imperiled by the Iranian hostage crisis, the Soviet invasion of Afghanistan, near-catastrophe at a Pennsylvania nuclear plant, aviation accidents, serial killers on the loose, and endless gas lines. Backed by a reenergized conservative Republican base, Reagan ran on the campaign slogan “Make America Great Again”—and prevailed. Reaganland is the story of how that happened, tracing conservatives’ cutthroat strategies to gain power and explaining why they endure four decades later.

Download or read book Longitude written by Dava Sobel and published by Bloomsbury Publishing USA. This book was released on 2010-07-05 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem." Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.

Download or read book Mapping Travel written by Jordana Dym and published by BRILL. This book was released on 2021-08-30 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on a thousand years of European travel writing and mapmaking, Dym suggests that after centuries of text-based itineraries and on-the spot directions guiding travelers and constituting their reports, maps in the fifteenth century emerged as tools for Europeans to support and report the results of land and sea travel. With each succeeding generation, these linear journey maps have become increasingly common and complex, responding to changes in forms of transportation, such as air and motor car ‘flight’ and print technology, especially the advent of multi-color printing. This is their story.

Book excerpt: Space... the final art frontier... What is it like to walk through an alien world? Artists have been imagining otherworldly landscapes for hundreds of years—but only in the past few decades have we started to see what other planets and moons really look like. These exciting scientific discoveries have led to ever more "realistic" space art.Space Artshows artists how to capture and create these partly real, partly imagined vistas by combining the latest facts with traditional landscape drawing. Put the two together and the results are memorable, dreamlike, haunting. AuthorMichael Carroll, one of the country's most distinguished astronomical artists, explains how to use washes and texturing, how to paint water and ice, rocks and geological formations, craters and alien skies. Linear and atmospheric perspective, color, composition, color, value, and shading are also covered as they relate to showing otherworldly landscapes. Fourteen paintings, building in complexity, are presented step-by-step, accompanied by NASA photos and the author’s own photos of mysterious landscapes closer to home: Death Valley, Iceland, Alaska. For everyone who has ever wanted to travel to far-off worlds... or just show what they’re imagining...Space Artis a rocket to the stars. • Combines the latest scientific research with landscape painting techniques • Author is one of the world’s foremost painters of space art • Twenty projects shown step by step—an art course in a book!

Download or read book Storm of Steel written by Mary R. Habeck and published by Cornell University Press. This book was released on 2014-08-22 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this fascinating account of the battle tanks that saw combat in the European Theater of World War II, Mary R. Habeck traces the strategies developed between the wars for the use of armored vehicles in battle. Only in Germany and the Soviet Union were truly original armor doctrines (generally known as "blitzkreig" and "deep battle") fully implemented. Storm of Steel relates how the German and Soviet armies formulated and chose to put into practice doctrines that were innovative for the time, yet in many respects identical to one another.As part of her extensive archival research in Russia, Germany, and Britain, Habeck had access to a large number of formerly secret and top-secret documents from several post-Soviet archives. This research informs her comparative approach as she looks at the roles of technology, shared influences, and assumptions about war in the formation of doctrine. She also explores relations between the Germans and the Soviets to determine whether collaboration influenced the convergence of their armor doctrines.

Book excerpt: Modern science communication has emerged in the twentieth century as a field of study, a body of practice and a profession—and it is a practice with deep historical roots. We have seen the birth of interactive science centres, the first university actions in teaching and conducting research, and a sharp growth in employment of science communicators. This collection charts the emergence of modern science communication across the world. This is the first volume to map investment around the globe in science centres, university courses and research, publications and conferences as well as tell the national stories of science communication. How did it all begin? How has development varied from one country to another? What motivated governments, institutions and people to see science communication as an answer to questions of the social place of science? Communicating Science describes the pathways followed by 39 different countries. All continents and many cultures are represented. For some countries, this is the first time that their science communication story has been told.
