The bicycle is a common, yet unique mechanical contraption in our world. In spite of this, the bike's physical and mechanical principles are understood by a select few. You do not have to be a genius to join this small group of people who understand the physics of cycling. This is your guide to fundamental principles (such as Newton's laws) and the book provides intuitive, basic explanations for the bicycle's behaviour. Each concept is introduced and illustrated with simple, everyday examples. Although cycling is viewed by most as a fun activity, and almost everyone acquires the basic skills at a young age, few understand the laws of nature that give magic to the ride. This is a closer look at some of these fun, exhilarating, and magical aspects of cycling. In the reading, you will also understand other physical principles such as motion, force, energy, power, heat, and temperature.
In Hope Draped in Black Joseph R. Winters responds to the enduring belief that America follows a constant trajectory of racial progress. Such notions—like those that suggested the passage into a postracial era following Barack Obama's election—gloss over the history of racial violence and oppression to create an imaginary and self-congratulatory world where painful memories are conveniently forgotten. In place of these narratives, Winters advocates for an idea of hope that is predicated on a continuous engagement with loss and melancholy. Signaling a heightened sensitivity to the suffering of others, melancholy disconcerts us and allows us to cut against dominant narratives and identities. Winters identifies a black literary and aesthetic tradition in the work of intellectuals, writers, and artists such as W. E. B. Du Bois, Ralph Ellison, Toni Morrison, and Charles Burnett that often underscores melancholy, remembrance, loss, and tragedy in ways that gesture toward such a conception of hope. Winters also draws on Walter Benjamin and Theodor Adorno to highlight how remembering and mourning the uncomfortable dimensions of American social life can provide alternate sources for hope and imagination that might lead to building a better world.
What are the chief challenges posed to contemporary democracy by modern technology, and how can democratic theory best respond to, or at least reflect on, those challenges? Inhabiting the kind of technologically advanced era in which we live, what sources are available within political theory for theoretical insight concerning the problem of democratic engagement with technology? The purpose of this volume is to canvas a broad range of theorists and theoretical traditions in order to address these questions, including Hegel and Marx, Rousseau and John Dewey, Heidegger and Simone Weil, Habermas and Walter Benjamin, Hannah Arendt and Hans Jonas. Commentaries on all these important thinkers -- focused on the issue of contemporary technology as posing unique social and political challenges for democratic political life -- yields rich and ambitious resources for theoretical reflection.
Air-Conditioning in Modern American Architecture, 1890–1970, documents how architects made environmental technologies into resources that helped shape their spatial and formal aesthetic. In doing so, it sheds important new light on the ways in which mechanical engineering has been assimilated into the culture of architecture as one facet of its broader modernist project. Tracing the development and architectural integration of air-conditioning from its origins in the late nineteenth century to the advent of the environmental movement in the early 1970s, Joseph M. Siry shows how the incorporation of mechanical systems into modernism’s discourse of functionality profoundly shaped the work of some of the movement’s leading architects, such as Dankmar Adler, Louis Sullivan, Frank Lloyd Wright, Ludwig Mies van der Rohe, Gordon Bunshaft, and Louis Kahn. For them, the modernist ideal of functionality was incompletely realized if it did not wholly assimilate heating, cooling, ventilating, and artificial lighting. Bridging the history of technology and the history of architecture, Siry discusses air-conditioning’s technical and social history and provides case studies of buildings by the master architects who brought this technology into the conceptual and formal project of modernism. A monumental work by a renowned expert in American modernist architecture, this book asks us to see canonical modernist buildings through a mechanical engineering–oriented lens. It will be especially valuable to scholars and students of architecture, modernism, the history of technology, and American history.
In November, 1864, Major General William Tecumseh Sherman led an army of veteran Union troops through the heart of the Confederacy, leaving behind a path of destruction in an area that had known little of the hardships of war, devastating the morale of soldiers and civilians alike, and hastening the end of the war. In this intensively researched and carefully detailed study, chosen by Civil War Magazine as one of the best one hundred books ever written about the Civil War, Joseph T. Glatthaar examines the Savannah and Carolinas Campaigns from the perspective of the common soldiers in Sherman's army, seeking, above all, to understand why they did what they did. Glatthaar graphically describes the duties and deprivations of the march, the boredom and frustration of camp life, and the utter confusion and pure chance of battle. Quoting heavily from the letters and diaries of Sherman's men, he reveals the fears, motivations, and aspirations of the Union soldiers and explores their attitudes toward their comrades, toward blacks and southern whites, and toward the war, its destruction, and the forthcoming reconstruction.
