Current Activities

      In July 2017 my problem book with Y Z Zou and Jon Kane was published at World PublishingCooperation (Beijing) .
 This book American Mathematical Contests, A Guide to Success,  is designed for use by both American and Chinese high     school students. It consists of six parts in four volumes, Basic Knowledge, Essays, Practice Problems, Past Contest Problems (including MATHCOUNTS, ARML, Purple Comet, AMC8, AMC10, AMC12, AIME, and several others. Here's a video intro to the book. The new edition is expected in 2021. The KendallHunt version for the US and Europe is ready. It's 720 pages, sells for $60 (8 cents per page, roughly). Order it at KH.


  Buy my book The Contest Problem Book VII for in pdf form ( $51.00 at Amazon). You can buy it from the MAA or at The Art of Problem Solving Website

General Information about me

I'm married to a wonderful woman Betty Baker Reiter. I'm proud that at the age of 56 she was awarded a PhD from the University of South Carolina. She is retired now after a successful career teaching mathematics and computer science at UNC Charlotte, Winthrop University, University of Hawaii, Davidson College and Central Piedmont Community College. Betty also taught at Clemson University and Richmond College (London) during the years we spent in those places.   

I'm also proud of Betty's and my daughter Ashley Reiter Ahlin who received her PhD. at University of Chicago in June 2002 working in the area of Geometric Algebra. She lives in East Lansing, Michigan where her husband Chris is a professor of Economics at Michigan State University. I maintain a list of articles by and about Ashley at  http://webpages.uncc.edu/~hbreiter/ashley.htm . An interview of Ashley for Cogito took place in 2010.

Check out my grandsons, Peter Ahlin, born June 24, 2006 and John Ahlin. Here are others taken in March 2009: Peter, John, John and Peter. Our youngest grandchild is Elizabeth Joy Ahlin, born July 5, 2009, and in March 2010, in Orlando here she is. Finally, here's the whole family at Disney.
