Expanding the Envelope is the first book to explore the full panorama of flight research history, from the earliest attempts by such nineteenth century practitioners as England's Sir George Cayley, who tested his kites and gliders by subjecting them to experimental flight, to the cutting-edge aeronautical research conducted by the NACA and NASA. Michael H. Gorn explores the vital human aspect of the history of flight research, including such well-known figures as James H. Doolittle, Chuck Yeager, and A. Scott Crossfield, as well as the less heralded engineers, pilots, and scientists who also had the "Right Stuff." While the individuals in the cockpit often receive the lion's share of the public's attention, Expanding the Envelope shows flight research to be a collaborative engineering activity, one in which the pilot participates as just one of many team members. Here is more than a century of flight research, from well before the creation of NACA to its rapid transformation under NASA. Gorn gives a behind the scenes look at the development of groundbreaking vehicles such as the X-1, the D-558, and the X-15, which demonstrated manned flight at speeds up to Mach 6.7 and as high as the edge of space.
"Much has been written about the famous conflicts and battlegrounds of the East during the American Revolution. Perhaps less familiar, but equally important and exciting, was the war on the western frontier, where Ohio Valley settlers fought for the land they had claimed -- and for their very lives. George Rogers Clark stepped forward to organize the local militias into a united front that would defend the western frontier from Indian attacks. Clark was one of the few people who saw the importance of the West in the war effort as a whole, and he persuaded Virginia's government to lend support to his efforts. As a result Clark was able to cross the Ohio, saving that part of the frontier from further raids. Lowell Harrison captures the excitement of this vital part of American history while giving a complete view of George Rogers Clark's significant achievements. Lowell H. Harrison, is a professor emeritus of history at Western Kentucky University and is the author or co-author of numerous books, including Lincoln of Kentucky, A New History of Kentucky, and Kentucky's Governors."
Challenges the market and creates discussions on the basis of concrete material. This book also focuses on non technological topics. It discusses items such as issues of strategy and the analysis of customer desires and demands.
This title explores the realm of art and architecture across a broad terrain of installation practices, revealing a critical territory that has been historically defined as a negativity: the progeny of that which is both not-architecture and not-art.
Robert Naeye is renowned for his lucid contributions to Astronomy, the world's biggest selling astronomy magazine. In Through the Eyes of Hubble: The Birth, Life and Violent Death of Stars, he uses 100 striking color images from the Hubble Space Telescope to illuminate the mind-stretching story of how stars are born, live, and die. Although focusing on astrophysics, the account is compelling, equation free, and accessible to everyone. In addition, there are eight beautiful paintings to appreciate, including works by the most famous living space artist, Michael Carroll.
