On March 8, 2008, I gave the third invited talk at the LACC High School Math Contest, How do you know what time it is: The Difference between clock time and solar time. The slide show, with additional text for explanation, is now available here.

This summer (2008) I was again director of IPAM's Research in Industrial Projects for Students (RIPS). I have directed RIPS for eight summers, since its inception in 2001.

I summarized RIPS and the management tools I use as RIPS director in a slide presentation (pdf) shown during the panel Starting and maintaining a student industrial research progam in the mathematical sciences at the MAA's MathFest August 4, 2007 in San Jose, California.

In 2006, fifty years after winning the Los Angeles City College Highschool Math Contest, I was invited to give a presentation at the contest and talked about eigenvalues and eigenvectors. Invited again in 2007, I gave a talk entitled Mathematical Misnomers: Hey, who really discovered that theorem! (pdf). I drew the talk from work I had done in reconsiderig the consequences of Kepler's Laws, starting from scratch. After deriving the inverse-square law and how it (in turn) implies Kepler's laws, I looked to see how the results were discovered originally. That's when I found many of the surprising things I put in the talk. Here are my notes on Kepler's Elliptical Orbits of the Planets and Newton's Inverse-square Law of Gravitation (pdf).

Ray Redheffer remembered 2005

I knew Ray from the time I was fifteen years old. My memories are the perspective of a grateful friend from early years. For a professional profile of Ray by his colleague Theodore Gamelin, see the perspective from UCLA, where he taught for 55 years and published over 200 mathematical papers.
