About Keith Stroyan

One of my main interests is using computing to help students learn and apply mathematics.  This site has a number of interactive programs both about courses and my research.  Many samples of my course materials and several texts are also included. Click the text icons or links above.

I am also interested in modern infinitesimal numbers.  In 1960 Abraham Robinson showed how to make Leibniz’ approach to calculus rigorous in the sense of modern mathematics.  (He called the theory “non-standard analysis” although the theory is an ordinary part of set theory.)  There is a brief course on infinitesimals on this site and references to my research. Click the Infinitesimals link.

A few years ago Mark Nawrot (NDSU) and I developed a mathematical model for the perception of depth from “motion parallax” that answered some open questions.  We are actively developing and testing the theory in his lab.
