I am a former Associate Professor of Mathematics at the University of Iowa turned (due to the innate adventurous spirit) software developer. Since venturing into commercial world about 20 years ago I worked on many projects, acquired a variety of practical skills, and still haven't forgotten everything I learned and knew in my previous life. Cut The Knot Software is my business incarnation. We offer a combination of teaching and programming experience and a deep attachment to mathematics.

I maintain the site Interactive Mathematics Miscellany and Puzzles, although, with time, the number of contributions from various people grew considerably. The overall responsibility is mine as are the errors (please report if you find any), but I am happy to acknowledge my debt to William McWorter (late), Scott E. Brodie, Nathan Bowler, Stuart Anderson and Hubert Shutrick without whose original contributions the site would not probably be the same, naturally.

The site is a free-to-all undertaking supported by advertisement and sales through an amazon.com store.
