This edition enhanced by the addition of experiments on thermioonics and the application of vacuum tubes to control problems, by the addition of transmission-line experiments, and carryin the machinery work to a more advanced level. Several earlier experiments now deemed of lesser value were ommitted. The number of experiments in the electrical-measuremeents field were doubled from previous editions. The fifth impression of the third edition. Originally published in 1922.
“Jay Wright Forrester (July 14, 1918 – November 16, 2016) was a pioneering American computer engineer and systems scientist. He is credited with being one of the inventors of magnetic core memory, the predominant form of random-access computer memory during the most explosive years of digital computer development (between 1955 and 1975). It was part of a family of related technologies which bridged the gap between vacuum tubes and semiconductors by exploiting the magnetic properties of materials to perform switching and amplification. He is also believed to have created the first animation in the history of computer graphics, a "jumping ball" on an oscilloscope.“ (wikipedia)
