From Whirlwind to MITRE


Book Description

The book shows how the wartime alliance of engineers, scientists, and the military exemplified by MIT's Radiation Lab helped to transform research and development practice in the United States through the end of the Cold War period. This book presents an organizational and social history of one of the foundational projects of the computer era: the development of the SAGE (Semi-Automatic Ground Environment) air defense system, from its first test at Bedford, Massachusetts, in 1951, to the installation of the first unit of the New York Air Defense Sector of the SAGE system, in 1958. The idea for SAGE grew out of Project Whirlwind, a wartime computer development effort, when the U.S. Department of Defense realized that the Whirlwind computer might anchor a continent-wide advance warning system. Developed by MIT engineers and scientists for the U.S. Air Force, SAGE monitored North American skies for possible attack by manned aircraft and missiles for twenty-five years. Aside from its strategic importance, SAGE set the foundation for mass data-processing systems and foreshadowed many computer developments of the 1960s. The heart of the system, the AN/FSQ-7, was the first computer to have an internal memory composed of "magnetic cores," thousands of tiny ferrite rings that served as reversible electromagnets. SAGE also introduced computer-driven displays, online terminals, time sharing, high-reliability computation, digital signal processing, digital transmission over telephone lines, digital track-while-scan, digital simulation, computer networking, and duplex computing. The book shows how the wartime alliance of engineers, scientists, and the military exemplified by MIT's Radiation Lab helped to transform research and development practice in the United States through the end of the Cold War period.

Systems, Experts, and Computers


Book Description

This groundbreaking book charts the origins and spread of the systems movement. After World War II, a systems approach to solving complex problems and managing complex systems came into vogue among engineers, scientists, and managers, fostered in part by the diffusion of digital computing power. Enthusiasm for the approach peaked during the Johnson administration, when it was applied to everything from military command and control systems to poverty in American cities. Although its failure in the social sphere, coupled with increasing skepticism about the role of technology and "experts" in American society, led to a retrenchment, systems methods are still part of modern managerial practice. This groundbreaking book charts the origins and spread of the systems movement. It describes the major players including RAND, MITRE, Ramo-Wooldrige (later TRW), and the International Institute of Applied Systems Analysis—and examines applications in a wide variety of military, government, civil, and engineering settings. The book is international in scope, describing the spread of systems thinking in France and Sweden. The story it tells helps to explain engineering thought and managerial practice during the last sixty years.




Blind Bombing


Book Description

Silver Medal winner in the Independent Book Publishers Awards Late in 1939 Nazi Germany was poised to overrun Europe and extend Adolf Hitler's fascist control. At the same time, however, two British physicists invented the resonant cavity magnetron. About the size of a hockey puck, it unlocked the enormous potential of radar exclusively for the Allies. Since the discovery of radar early in the twentieth century, development across most of the world had progressed only incrementally. Germany and Japan had radar as well, but in just three years, the Allies' new radar, incorporating the top-secret cavity magnetron, turned the tide of war from doubtful to a known conclusion before the enemy even figured out how. The tactical difference between the enemy's primitive radar and the Allies' new radar was similar to that between a musket and a rifle. The cavity magnetron proved to be the single most influential new invention contributing to winning the war in Europe. Norman Fine tells the relatively unknown story of radar's transformation from a technical curiosity to a previously unimaginable offensive weapon. We meet scientists and warriors critical to the story of radar and its pressure-filled development and implementation. Blind Bombing brings to light two characters who played an integral role in the story as it unfolded: one, a brilliant and opinionated scientist, the other, an easygoing twenty-one-year-old caught up in the peacetime draft. This unlikely pair and a handful of their cohorts pioneered a revolution in warfare. They formulated new offensive tactics by trying, failing, and persevering, ultimately overcoming the naysayers and obstructionists on their own side and finally the enemy.

A Century of Electrical Engineering and Computer Science at MIT, 1882-1982


Book Description

The book's text and many photographs introduce readers to the renowned teachers and researchers who are still well known in engineering circles. Electrical engineering is a protean profession. Today the field embraces many disciplines that seem far removed from its roots in the telegraph, telephone, electric lamps, motors, and generators. To a remarkable extent, this chronicle of change and growth at a single institution is a capsule history of the discipline and profession of electrical engineering as it developed worldwide. Even when MIT was not leading the way, the department was usually quick to adapt to changing needs, goals, curricula, and research programs. What has remained constant throughout is the dynamic interaction of teaching and research, flexibility of administration, the interconnections with industrial progress and national priorities. The book's text and many photographs introduce readers to the renowned teachers and researchers who are still well known in engineering circles, among them: Vannevar Bush, Harold Hazen, Edward Bowles, Gordon Brown, Harold Edgerton, Ernst Guillemin, Arthur von Hippel, and Jay Forrester. The book covers the department's major areas of activity -- electrical power systems, servomechanisms, circuit theory, communications theory, radar and microwaves (developed first at the famed Radiation Laboratory during World War II), insulation and dielectrics, electronics, acoustics, and computation. This rich history of accomplishments shows moreover that years before "Computer Science" was added to the department's name such pioneering results in computation and control as Vannevar Bush's Differential Analyzer, early cybernetic devices and numerically controlled servomechanisms, the Whirlwind computer, and the evolution of time-sharing computation had already been achieved.
