To celebrate their re-release of his classic puzzle books, the Dover Math and Science Newsletter featured an interview with Raymond Smullyan, as well as several extended excerpts from his books. (For my math club students: Professor Smullyan invented the Knights and Knaves puzzles.) Enjoy!

## Blog Carnival Update

It seems like a corrolary to Murphy’s Law: Whenever I claim that the blog carnival site is working, it immediately goes on the blink. At any rate, I can’t get the site to load at all today. If you want to send in a post for the next math carnival, you can:

- Use the contact form at Math Is Not a Four-Letter Word.
- Use this mail-to link to email Bon directly.

Everyone is welcome — if you’ve written a blog post about learning, teaching, or just playing around with math, from preschool to calculus, please send us your link!

## What I’m Reading: Fermat’s Enigma

Homeschooling is much more than just doing school at home — it’s a lifelong lifestyle of learning. And thanks to the modern miracle of inter-library loan, even those of us who live in the middle of nowhere can get just about any book sent directly to our tiny home-town libraries.

As I mentioned in Math Teachers at Play 46, I’m trying to add more living books about math to our homeschool schedule, including my own self-education reading. So, a copy of Fermat’s Enigma: The Epic Quest to Solve the World’s Greatest Mathematical Problem finally showed up at my library, and I am thoroughly enjoying it.
