Description
This 32-page booklet was received with 1979.0601.02. Its citation information is: Maurice L. Hartung, How to Use the Deci Log Log Slide Rule (Chicago: Pickett & Eckel, Inc., 1947). Hartung, a University of Chicago professor and consultant to Pickett & Eckel, provided a basic overview of mathematical operations on the slide rule. He then explained placing the decimal point; the inverted scales; scales for squares and cubes, logarithms, and trigonometry; and solving problems using multiple scales. He next described the log log scales in a section that has several diagrams of slide rules.
A pink paper sheet on caring for the slide rule is inside the booklet. A previous owner has written in a few corrections, including an updated population of the United States of 175 million in 1957.
