Pickett Manual for Dual Base Log Log Slide Rules

Description
Pickett, Inc., was a slide rule manufacturer that started in Chicago in 1943, shifted most of its operations to Alhambra, Calif., in 1946, and moved to Santa Barbara, Calif., in 1964. Maurice L. Hartung, a mathematics professor at the University of Chicago, wrote several instruction manuals for the company, including How to Use Dual Base Log Log Slide Rules. This 93-page booklet was intended for use with Pickett models 2, 3, and 4. It contains sections on the general operation of a slide rule, the use of scales for trigonometry and roots, elementary vector methods, the use of logarithmic scales, practice problems, hyperbolic functions, and circular functions. Hartung also showed how the double T scales could solve side-angle-side triangle problems in one step. Model 600 was advertised at the back of the manual, and instructions for caring for Pickett slide rules were provided inside the back cover.
Although Hartung wrote the manual in 1947, this printing was made after the company moved to Santa Barbara in 1964. See the associated items, 1980.0097.01 and 1980.0097.06.
