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 below or textbooks link 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” after a technical name in logic.)  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. Click the Vision link.

I live in rural Johnson county with my Labrador retrievers. My daughter lives near Chicago. Click the Shohola Labs link and look at the My Prairie link in there.
