The second book in a new series by MIT designed to overhaul the curriculum related to Electrical Engineering. Other volumes were "Electric Circuits" and "Applied Electronics". Intended as an introductory course applicable regardless of a student's eventual specialization. It apparently appeared on Forrester's shelf on Feb 20, 1947, mere months before Bell Labs demonstrated the transistor (Dec. 23, 1947).
Relevant to Forrester's work toward magnetic core memory and a nice ownership as a result.
"Jay Forrester was born near Anselmo, Nebraska, in 1918. He holds a B.S.. in electrical engineering from the University of Nebraska (1939) and an M.S. from MIT (1945). While leading the MIT Whirlwind computer project (1947-1953), Forrester developed the "coincident-current" magnetic core memory system, the first reliable, high-speed random access memory for digital computers. This invention was of monumental importance to the further advancement of digital computers and was used for main computer memory in most computers into the 1970s." (computer history museum bio)
