Analog Calculators and Computers Library Lecture

The Galvin Library presents a talk, “Analog Calculators and Computers” by STEM librarian Charles Uth on Friday, September 22, from Noon–1 p.m. in the upper level of the Galvin Library. This event is open to the public.

Before the development of inexpensive electronic calculators and personal computers in the 1970s and 1980s, various types of mechanical analog calculators were in widespread use. These included numerical tables, nomograms (a graphical method of solving complex equations), abacuses, adding machines, and slide rules. This presentation will briefly discuss the history of mechanical analog devices and demonstrate the use of nomograms and slide rules.
