Over the past eight decades, developments in vertical lift aircraft--both helicopters and vertical/short takeoff and landing (V/STOL) planes--have given the American military unparalleled capabilities on the modern battlefield. The U.S. has led the world in vertical lift technologies with the help of some of the brightest minds in this field--Igor I. Sikorsky, Arthur M. Young, Frank N. Piasecki, Charles H. Kaman and Stanley Hiller, Jr., to name a few--and by having the industrial prowess to make their concepts reality. This book provides a concise historical survey, including technical specifications, drawings, and photographs of every type of helicopter and V/STOL aircraft developed for the U.S. military, from the earliest examples tested in 1941 and 1942, up to the newest prototypes.

Li Er, whose innovative works of fiction have earned the admiration of scholars and critics—and a passionate fan base of readers—is one of China’s most prominent writers. This landmark publication of his Coloratura, a tour de force of literary innovation, marks the first translation of the author’s novels into English. Set against the turbulent backdrop of the Chinese Civil War, Coloratura revolves around the mysterious Ge Ren, whose story is told by three narrators and a host of other voices. Who was Ge Ren really? Just about the only thing anyone can agree on is that he is dead. But how he died, and who he was when alive, are less than certain. Was Ge Ren a hero, a Nationalist or Communist, a poet, translator, scholar, or spy—or some combination of all these identities? And how much of his story is merely fanciful “coloratura” nonsense? As different factions fight for control of China, Ge Ren traverses the political and intellectual life of the country, managing to affect countless lives. Years later, in the present day, his final surviving descendant, the intriguing “compiler” of the novel, pieces together the stories of her enigmatic ancestor from a patchwork of narrators, reliable or otherwise, and historical documents, real or invented. But readers also will wonder if she has an agenda of her own. The search for Ge Ren takes us from Chairman Mao’s stronghold at Yan’an to a barren People’s Commune, and then farther afield, with excursions into Russia, Japan, and even a small town in England. Many of the characters and incidents are actual historical figures and events, woven seamlessly into the fictional storyline. Told with swashbuckling brio and painstaking historical detail, Coloratura is both an illuminating journey through twentieth-century Chinese history and a profound exploration of the elusive nature of truth.

A thousand years before Isaac Asimov set down his Three Laws of Robotics, real and imagined automata appeared in European courts, liturgies, and literary texts. Medieval robots took such forms as talking statues, mechanical animals, and silent metal guardians; some served to entertain or instruct while others performed disciplinary or surveillance functions. Variously ascribed to artisanal genius, inexplicable cosmic forces, or demonic powers, these marvelous fabrications raised fundamental questions about knowledge, nature, and divine purpose in the Middle Ages. Medieval Robots recovers the forgotten history of fantastical, aspirational, and terrifying machines that captivated Europe in imagination and reality between the ninth and fourteenth centuries. E. R. Truitt traces the different forms of self-moving or self-sustaining manufactured objects from their earliest appearances in the Latin West through centuries of mechanical and literary invention. Chronicled in romances and song as well as histories and encyclopedias, medieval automata were powerful cultural objects that probed the limits of natural philosophy, illuminated and challenged definitions of life and death, and epitomized the transformative and threatening potential of foreign knowledge and culture. This original and wide-ranging study reveals the convergence of science, technology, and imagination in medieval culture and demonstrates the striking similarities between medieval and modern robotic and cybernetic visions.
