I must admit, part of my fascination with computers and mathematics has to do with my early exposure to Martin Gardner’s absolutely fantastic *Mathematical Games* columns in *Scientific American*. As a grade school student, I remember reading these columns and through them, discovering for the first time the actual *excitement* of mathematics. It’s hard to explain to people who don’t share this particular penchant for mathematics, but there it is. *Mathematical Games* was important.

When Gardner finally retired from *Scientific American*, one of his eventual replacements was A.K. Dewdney, who renamed the column to *Computer Recreations*. While no one could replace Gardner, I found Dewdney’s columns to be fun and thought provoking. I have several of his books.

And here’s what’s sad: Dewdney is apparently has decided to become a 9/11 denier.

Jeffrey Shallit attended a “debate” where Dewdney was a speaker. He wrote it up in two parts: Part 1 Part 2. It’s sad. Really, really sad when someone you respect shows that they don’t deserve it.
