Another question regarding terminology. In "Models, Simulation, and 'Computer Experiments'", Evelyn Fox Keller says that before the likely seeming date of 1947, when the OED records the first positive use of "simulation", the word "invariably meant deception" (p. 198). But a closer look, into publications of electrical engineers back to the early 20th Century, reveals uses of 'simulation' straightforwardly to denote the behaviour of electrical circuits designed as analogues of physical phenomena. (My source is the IEEE Xplore Digital Library.) Despite hints that simulation was in effect being practiced in the 19th Century, e.g. by Kelvin and Babbage, I cannot find any use of the *word* to denote a constructed analogical likeness. Perhaps not coincidentally the first occurrences I've found coincide roughly with electricity becoming familiar enough that it could be used to explore less familiar phenomena rather than the other way around. (Charles Care's work bears on this point.) Does anyone here know more? (I did try the archive, but it reports a "ht://Dig error", commenting that, "Unable to read word database file '/dh/mailman/grail/archives/private/members-sigcis.org/htdig/db.words.db' Did you run htdig?")
