The dramatic, untold story of the brilliant team whose feats of innovation and engineering created the world’s first digital electronic computer—decrypting the Nazis’ toughest code, helping bring an end to WWII, and ushering in the information age. Planning the invasion of Normandy, the Allies knew that decoding the communications of the Nazi high command was imperative for its success. But standing in their way was an encryption machine they called Tunny (British English for “tuna”), which was vastly more difficult to crack than the infamous Enigma cipher. To surmount this seemingly impossible challenge, Alan Turing, the Enigma codebreaker, brought in a maverick English working-class engineer named Tommy Flowers who devised the ingenious, daring, and controversial plan to build a machine that would calculate at breathtaking speed and break the code in nearly real time. Together with the pioneering mathematician Max Newman, Flowers and his team produced—against the odds, the clock, and a resistant leadership—Colossus, the world’s first digital electronic computer, the machine that would help bring the war to an end. Drawing upon recently declassified sources, David A. Price’s Geniuses at War tells, for the first time, the full mesmerizing story of the great minds behind Colossus and chronicles the remarkable feats of engineering genius that marked the dawn of the digital age.
The extraordinary wartime exploits of the British codebreakers based at Bletchley Park continue to fascinate and amaze. In The Emperor's Codes Michael Smith tells the story of how Japan's wartime codes were broken, and the consequences for the Second World War. He describes how the Japanese ciphers were broken and the effect on the lives of the codebreakers themselves. Using material from recently declassified British files, privileged access to Australian secret official histories and interviews with British, American and Australian codebreakers, this is the first full account of the critical role played by Bletchley Park and its main outposts around the world.
Based on nearly a decade of scholarship, this is a highly focused book on the implications of postmodernism for the construction and assessment of theory and practice in educational administration. Current ideas of practice are deconstructed, from the notions of sound research to the use of national standards in the preparation of educational leaders along with ways of examining and resolving the theory-practice gap. Part One of the book contains chapters dealing with the rise of postmodernism and describes its broad-based dissent from a century of thought in the field, including a penetrating examination of whether the concept of a field itself is viable. Part Two of the book explores the many ramifications of postmodernism to practice, beginning with ideas concerning educational research. These chapters tackle the tough issues of the efficacy of the Interstate Leaders Licensure Standards (ISLLC) and the national exam as examples of job deskilling and deprofessionalization in the guise of raising standards of preparation of future educational leaders. Other chapters deal with deconstructing the popular managerial ideas contained in Stephen Covey's works and dispute Joe Murphy's call for a new center of gravity in the field as reinforcing the status quo. Finally, the book tackles the issue of the theory-practice gap and indicates that new and progressive theories which anticipate problems of practice are what is required to deal with this persistent issue. The book contains many helpful exhibits in understanding the issues concerning theory and practice, as well as a glossary of terms most commonly found in postmodern discourse. This book is designed for college and university programs engaged in the preparation of educational leaders for ele-mentary/secondary schools and college administrative positions.
This Congress Volume comprises not only the main lectures of the XVIth I.O.S.O.T. Congress, held in Oslo 1998, but also the interventions at the two panels on "Intertextuality and the Pluralism of Methods" and on "The Hebrew Bible and History". Both the main lectures and the panelists' interventions focus on current methodological problems and study central questions in the present study of the Hebrew Bible/Old Testament in its environment.
The first scholarly book to present an in-depth exploration of the historical relationships between covert intelligence work and information/computer science. The book first examines the pivotal strides made during World War II to utilize technology in the gathering and dissemination of government/military intelligence. Next, it traces the evolution of the relationship between spymasters, computers, and systems developers through the years of the Cold War-a period notable for the parallel development of high-tech spyware and powerful systems for encoding, decoding, storing, and manipulating intelligence data.
Many women scientists, particularly those who did crucial work in two world wars, have disappeared from history. Until they are written back in, the history of science will continue to remain unbalanced. This book tells the story of Elizabeth Alexander, a pioneering scientist who changed thinking in geology and radio astronomy during WWII and its aftermath.Building on an unpublished diary, recently declassified government records and archive material adding considerably to knowledge about radar developments in the Pacific in WWII, this book also contextualises Elizabeth's academic life in Singapore before the war, and the country's educational and physical reconstruction after it as it moved towards independence.This unique story is a must-read for readers interested in scientific, social and military history during the WWII, historians of geology, radar, as well as scientific biographies.
