In 1941, naval Headache personnel with receivers to eavesdrop on Luftwaffe wireless transmissions were embarked on warships and from May 1942, ships gained RAF Y computor parties, which sailed with cruiser admirals in command of convoy escorts, to interpret Luftwaffe W/T signals intercepted by the Headaches. The Admiralty sent details of Luftwaffe wireless frequencies, call signs and the daily local codes to the computors, which combined with their knowledge of Luftwaffe procedures, could glean fairly accurate details of German reconnaissance sorties. Sometimes computors predicted attacks twenty minutes before they were detected by radar.

Before the 1920s, computers (sometimes computors) were human clerks that performed computations. They were usually under the lead of a physicist. Many thousands of computers were employed in commerce, government, and research establishments. Most of these computers were women.

The Victor would have three segmented wings of crescent shape, each with a different sweep angle. Weber assisted with the calculations, and incorporated further design improvements including the engine air inputs based on the work she had done with Küchemann during the war. Her linear and simple aerodynamic models were calculated by hand by a team of women 'computors'. In September 1945, she co-wrote with Küchemann a paper analysing the aerodynamics of the new wing and fuselage.

Kister 1994 pp.156, 160 Articles were arranged topically under headings such as "Animals", "Computors", "Government and Law" etc. The set contained much practical advise, including how to write a resume, follow the stock market, save energy, conduct a self breast examination and "Do's and Don'ts of Pregnancy".Kister 1994 pp.157-8 There was also an optional supplementary third volume which contained information for taking standardized tests and a full color world atlas. The physical format now included thumb indexes with fore-edges showing where each topical chapter began.Kister 1994 pp.

An example that uses Euclid's algorithm appears below. Computers (and computors), models of computation: A computer (or human "computor"In his essay "Calculations by Man and Machine: Conceptual Analysis" Seig 2002:390 credits this distinction to Robin Gandy, cf Wilfred Seig, et al., 2002 Reflections on the foundations of mathematics: Essays in honor of Solomon Feferman, Association for Symbolic Logic, A.K. Peters Ltd, Natick, MA.) is a restricted type of machine, a "discrete deterministic mechanical device"cf Gandy 1980:126, Robin Gandy Church's Thesis and Principles for Mechanisms appearing on pp. 123–148 in J.
