Sommario/riassunto

Das Buch widmet sich AN/FSQ-7, einem der aussergewöhnlichsten und einflussreichsten Digitalrechner aller Zeiten, über den erst in den letzten Jahren (aufgrund von Geheimhaltungsvorschriften) detaillierte Informationen zugänglich wurden. Über einen Zeitraum von über 30 Jahren wurden in den USA 23 Rechenzentren auf Basis von jeweils zwei AN/FSQ-7 betrieben, die das Herz von SAGE, dem Semi Automatic Ground Environment bildeten, das für die Luftraumüberwachung der USA und (in Teilen) Kanada zuständig war.

One of the most impressive computer systems ever was the vacuum tube based behemoth AN/FSQ-7, which was the heart of the ''Semi Automatic Ground Environment''. Machines of this type were children of the Cold War and had a tremendous effect in politics. They also



generated a vast amount of spin-offs which still shape our world. This book focuses on the technological achievements and details of this marvelous machine and of its predecessor Whirlwind. The various developments, ranging from magnetic core memory to data transmission via telephone lines, are covered in detail with schematics, circuit descriptions and small programming examples. This book is a treasure trove for those interested in the technology of early digital computers and those interested in the impact these machines had and still have on our current computer systems.

Problems -- Solutions -- The tool chest -- Index of problems.

Sommario/riassunto

This book contains 500 problems that range over a wide spectrum of areas of high school mathematics and levels of difficulty. Some are simple mathematical puzzlers while others are serious problems at the Olympiad level. Students of all levels of interest and ability will be entertained and taught by the book. For many problems, more than one solution is supplied so that students can see how different approaches can be taken to a problem and compare the elegance and efficiency of different tools that might be applied.   Teachers at both the college and secondary levels will find the book useful, both for encouraging their students and for their own pleasure. Some of the problems can be used to provide a little spice in the regular curriculum by demonstrating the power of very basic techniques.   This collection



provides a solid base for students who wish to enter competitions at the Olympiad level. They can begin with easy problems and progress to more demanding ones. A special mathematical tool chest summarizes the results and techniques needed by competition-level students.
