The VHS copies described here do not contain the full-length version of the 1953 film "Making Electrons Count", only the J. Forrester and "Programming at 3am" segments. In the J. Forrester segment of the film, applications of the Whirlwind in various contexts are presented, including geology, aeronautics, wind tunnel research, chemistry and optical research. This segment of the film is followed by "Programming at 3am," a sequence in which a physicist at Massachusetts General Hospital describes the process of using the Whirlwind to design an optical instrument. The physicist is shown using punched tape and interacting with engineers and programmers in the process of running and debugging his program overnight. From this segment: "Whirlwind was able to do in a few hours lens computations that would have taken several man-years manually."
