For terrific math puzzles check out Erich Friedman’s website

In the last few days of camp this summer, a big folder of puzzles got posted in the hall. In the folder was a collection of Erich Friedman’s Hamiltonian Mazes puzzles.

These puzzles are terrific (hard!) and it’s just one of many many different types of puzzles and problems on Erich’s site.

The whole site is a terrific snapshot of the old internet, with its generosity and quirk. I love the little personal nuggets Erich includes on his homepage (I’m nostalgic for homepages!):

I am a Libertarian and an Atheist. I consider myself a Feminist, and I’m a member of the ACLU. I have memorized the first 50 digits of Pi. I am an INTJ and I Juggle. I build card houses, and I’m interested in my Family Tree.

For the record: I am a Capitalist and a Religious Jew. I consider myself a Feminist, and I’m a patron of NYPL. I recently memorized the Largest Known Prime Number. I sometimes get Moody and Sad but I don’t Juggle. I’m interested in my Family.

I own the largest Puzzle Collection in Florida.

Really, lots of wonderful stuff on his site. In the past I’ve been more interested in theory-laden areas of math than puzzles and problems (I like my math how I like my philosophy) but I always have fun when I do find time for these sorts of things.

Like these square tilings. They’re gorgeous!


Anyway, a wonderful website. Enjoy!

  1. Cool I can use those. Incidentally, the web site does seem very retro in style. If you didn’t know what you were looking for, a page would be easy to miss. Someday I’m going to have to think about what I want to do about my own blog that way
