Object Details
- Description
- In 1950 and 1951, three Illinois Institute of Technology engineering professors participated in the development of the Versalog slide rule, manufactured by Hemmi of Tokyo, Japan, for the Frederick Post Company of Chicago. E. I. Fiesenheiser, R. A. Budenholzer, and B. A. Fischer subsequently prepared this 115-page hardcover volume explaining the slide rule's capabilities. They covered the care of the instrument, its twenty-three scales, multiplication and division, squares and cubes, exponentials and logarithms, and trigonometric operations. Each professor also contributed a chapter on applications in his specialty: civil, mechanical, or electrical engineering.
