    Readers will find themselves rethinking many of their bedrock assumptions: Should education transmit culture or defend us against it? Is technological innovation progress or a peculiarly American addiction? When everyone watches the same television programs -- and television producers don't discriminate between the audiences for Sesame Street and Dynasty -- is childhood anything more than a sentimental concept? Writing in the traditions of Orwell and H.L. Mencken, Neil Postman sends shock waves of wit and critical intelligence through the cultural wasteland.

    This was the first book in English on total productive maintenance (TPM) - a system which has been shown to reduce breakdowns to almost zero and increase worker productivity by as much as 150 percent.

    The concluding chapter describes an autonomous system that builds from experience an internal model of the world and bases its operation on that internal model. Close attention is paid to the engineering of the memory, including comparisons to ordinary computer memories."Sparse Distributed Memory "provides an overall perspective on neural systems. The model it describes can aid in understanding human memory and learning, and a system based on it sheds light on outstanding problems in philosophy and artificial intelligence. Applications of the memory are expected to be found in the creation of adaptive systems for signal processing, speech, vision, motor control, and (in general) robots. Perhaps the most exciting aspect of the memory, in its implications for research in neural networks, is that its realization with neuronlike components resembles the cortex of the cerebellum.Pentti Kanerva is a scientist at the Research Institute for Advanced Computer Science at the NASA Ames Research Center and a visiting scholar at the Stanford Center for the Study of Language and Information. A Bradford Book.

    Bruce Franklin brings the epic story of the superweapon and the American imagination into the ominous twenty-first century, demonstrating its continuing importance both to comprehending our current predicament and to finding ways to escape from it. Sweeping through two centuries of American culture and military history, Franklin traces the evolution of superweapons from Robert Fulton's eighteenth-century submarine through the strategic bomber, atomic bomb, and Star Wars to a twenty-first century dominated by "weapons of mass destruction," real and imagined. Interweaving culture, science, technology, and history, he shows how and why the American pursuit of the ultimate defensive weapon—guaranteed to end all war and bring universal triumph to American ideals—has led our nation and the world into an epoch of terror and endless war.

    In this study, the technological limitations of maritime traffic are considered in conjunction with the peculiar geographical conditions within which it operated, and which led to the establishment of major sea lanes on trunk routes along which traffic could move safely, efficiently, and economically. These trunk routes remained virtually unchanged from antiquity to the sixteenth century, and eventually constituted economic and strategic maritime frontiers between civilisations. At the same time, the technological limitations of the oared galley meant that coasts and islands along the trunk routes had also to be held, a necessity which favoured geographically the Christian West over the world of Byzantium and Islam.

    Army Air Forces. With its distinctive glazed nose and long, thin wings that provided both speed at high altitude and stability at takeoff and landing, the Superfortress was the first operational bomber with a pressurized crew cabin and featured advanced radar and avionics. Armed with remote-controlled machine gun turrets and a 20,000 pound bomb load, it was the first USAAF bomber capable of mastering the vast distances of the Pacific Theater of World War II. The prototype flew in September 1942 but a series of post-production modifications delayed the bomber's first mission until April 1944. Superfortresses began attacking Japan in daylight with conventional ordnance from high altitude, but their mission was redirected in March 1945, with massive low-level formations dropping incendiary bombs! at night on Japanese cities. The ensuing firestorms, followed by the complete destruction of Hiroshima and Nagasaki by atomic bombs dropped from two specially modified "silverplate" B-29s, forced Japan to cease fighting.Written by the man who led the B-29 into combat, Superfortress: The Boeing B-29 and American Airpower in World War II is an important document of one of the most turbulent times in world history. General Curtis LeMay recalls the early debate about whether or not the United States needed a long-range bomber, how the B-29 was created and produced despite the enormous logistical difficulties of the design, and the decision to conduct fire-bombings against Japan and ultimately drop the atomic bomb. Highly praised when it was first published, this new edition is complete with photographs, a new introduction, and statistical tables.

    Because of their speed and maneuverability, these "rakish topsail schooners" were quickly taken up by privateers, slavers, smugglers, and pirates. More often than not, to spot a Baltimore Clipper on the horizon was to spot trouble on the way.Until the publication of this book, little literature was available on these ships. The fascinating and beautifully illustrated volume corrected that deficiency, offering a detailed chronicle of the history and construction of the Baltimore Clipper — during the Revolution, its development from 1782 to 1812, role during the War of 1812, use as a slave ship, and eventual decline.The author, one of the foremost American authorities on sailing and sailing ships, has enhanced the text with over 70 meticulous line illustrations of sail plans, deck plans, and other features of some of the best-known Baltimore Clippers: the Ann McKim, the slave brig Diligente, H. M. Schooner Flying Fish, the French lugger Le Coureur, and many more. In addition, 36 halftone plates depict actual privateers, schooners, slavers, and other vessels, often in dramatic action or battle scenes.The authentic plans and details reproduced here make this book an invaluable reference for shipbuilding hobbyists. Moreover, its rich and comprehensive history of a fascinating era in maritime history will make it a welcome addition to the library of any lover of the great age of sail.

    The National Air and Space Museum (NASM) houses the world's greatest collection of historic aircraft and spacecraft plus an amazing assortment of other historic objects. Many fascinating items from the twenty-three galleries and two off-site facilities are presented here in 197 full-color photographs, and are accompanied by their equally intriguing stories.This gallery-by-gallery tour presents many milestones of aviation and spaceflight, such as the Wright Flyer, Chuck Yeager's Bell X-1, and the spacesuits worn by Neil Armstrong and Buzz Aldrin. Some of the lesser-known but equally captivating treasures illustrated here include soda cans specially engineered for space use, Otto Lilienthal's 1894 glider (which inspired the Wright brothers), and a sobering American flag recovered from the wreckage of the Challenger. Each gallery section concludes helpfully with notes about smaller objects and displays that are not to be missed.The final two sections are devoted to the museum's sprawling thirty-building Paul E. Garber Preservation, Restoration, and Storage Facility in Maryland -- where three-hour tours are available by reservation -- and the soon-to-be-opened Steven F. Udvar-Hazy Center at Dulles Airport. When completed, this facility will have enough space to finally display the Enola Gay, the first space shuttle (the Enterprise), and the fastest jet in the world, the ultrasleek SR-71 Blackbird.Certainly offering an enriched experience for any NASM visitor, this sturdy, richly detailedguide is also an inspiring tribute to the human spirit.

    The digital electronic computer is today's music machine. "The technology is now so accessible, " Curtis Roads observes, "that virtually any musician can set up a home computer music studio for research, composition, or play." "The Music Machine "brings together valuable primary source articles on the art, science, and technology of computer music for this growing community.The 54 articles including several major articles that are now out of print were published in Computer "Music Journal "between 1980 and 1985. The subject matter extends beyond that of a companion volume, "Foundations of Computer Music," which contains revised and updated articles from the years 1977 - 1979 on digital sound synthesis, synthesis hardware, music software, and psychoacoustics and signal processing. The new collection includes interviews with major figures in the field and articles devoted to composition, artificial intelligence, and the popular Musical Instrument Digital Interface. There is a new article on applications of the MIDI standard. The editor has written a preface and seven short overviews that summarize the contents of book's seven parts.Curtis Roads is a composer, a producer, and the editor of "Computer Music Journal."

    Therefore, all will be interested in this unique narrative by Admiral Wallin.The Navy has long needed a succinct account of the salvage operations at Pearl Harbor that miraculously resurrected what appeared to be a forever shattered fleet. Admiral Wallin agreed to undertake the job. He was exactly the right man for it – in talent, in perception, and in experience. He had served intimately with Admiral Nimitz and with Admiral Halsey in the South Pacific, has commanded three different Navy Yards, and was a highly successful Chief of the Bureau of Ships.On 7 December 1941 the then Captain Wallin was serving at Pearl Harbor. He witnessed the events of that shattering and unifying “Day of Infamy.” His mind began to race at high speeds at once on the problems and means of getting the broken fleet back into service for its giant task. Unless the United States regained control of the sea, even greater disaster loomed. Without victory at sea, tyranny soon would surely rule all Asia and Europe. In a matter of time it would surely rule the Americas.Captain Wallin salvaged most of the broken Pearl Harbor fleet that went on to figure prominently in the United States Navy’s victory. So the account he masterfully tells covers what he masterfully accomplished. The United States owes him an unpayable debt for this high service among many others in his long career.
