So! We have reached the end of the course. I would like encourage you to join one of the many groups around the world that are active in recreational math and puzzles.
A good place to start is the worldwide celebration of mind activities in honor of the late Martin Gardner. Alexander Bogomolny’s wonderful cut-the-knot website is a wonderful place to learn a vast number of recreational math topics. We have already mentioned Jorge Soares’s cryptarithm site and there are many other wonderful sites as well. There is no place better than Wikipedia and its inner references to start looking around for material on symbologies and barcodes.
Here is a full list of the Weizmann Institute’s courses.
Finally, if you’ve liked this course and are game for more puzzles, you might be interested in The Paper Puzzle Book which I wrote with fellow origamist Ilan Garibi and Puzzle maker David Goodman.
Thank you!
Thank you for being with me and enduring the whole course!
