Mathematical Foundations of the Slide Rule, by Professor Joe Pasquale, University of California, San Diego

Abstract: We present a mathematical principle that provides a precise formulation for the types of functions a slide rule can be designed to calculate. In addition to providing the mathematical foundations for how and why a slide rule works, this principle establishes its mathematical possibilities and limits. We also present the theory of how slide rule scales are constructed.
