Welcome to adventurous math for the playground crowd! I am Moby Snoodles, and I love to hear from you at

Moby Snoodles Math Googles


Book news

This week, we had the thrill of holding the full file of the book in front of our eyes. The front and back cover, Library of Congress and ISBN numbers, Table of Contents, everything! It was so tempting to rush the book to you right then! But we had to follow the plan for another round of quality assurance, with multiple people checking and re-checking everything. More than thirty corrections of layout, text-illustration correspondences, and typos later, the book is going to the printers and the ePub formatting. We will have to check on the printer’s proofs, as well. Like Zeno’s arrow, “Moebius Noodles” is approaching the error-free state. No book ever gets there, but we’ll get close enough for all practical purposes!

Meanwhile, here are three of many stages of our back cover design: the finished look with 3D models of the real opened book; the first schematic of the layout; and an early draft. The back cover is a diagram of how to navigate through the book. We thought it would be a bit more useful than the advance praise you traditionally find on back covers, which we love too, by the way. We will be aggregating reviews online.

Sol Lederman interviewed Maria Droujkova for his Inspired by Math series on notable modern mathematicians and mathematics educators. Why is there so much computer science in the “Moebius Noodles” book? What is math literacy? What is Maria’s secret plan for taking over the world? Listen to the podcast and find out!

Our Spanish-speaking readers will enjoy math videos by our book illustrator, Ever Salazar. But math is a universal language! Check out what Mary O’Keeffe (Albany Math Circle) is doing, after having found the videos via the Moebius Noodles Facebook page:

Thanks to Maria Droujkova for bringing this wondrous, brilliant, and engaging series of math videos in Spanish to my attention! It is a terrific way for me to pick up at least a little bit of mathematical Spanish before my trip to lead activities at a math festival in Mayaguez, Puerto Rico this weekend.

Math Goggles issue #7 is inspired by Keith Devlin’s MOOC (Massively Open Online Course) on mathematical thinking. It is about the ambiguity of our language, with examples from newspapers, such as “Teen found after ski slope disappearance” (where did the slope go?).

Math Goggles #8 invites you to make puzzles using LEGO and other 3D tools.

Find a math and logic puzzle that you’ve not seen or solved before. Now, build it with whatever it is you have handy – cardboard, wrapping paper and glue; modeling clay; marshmallows and toothpicks; building blocks. You might like the challenge of recreating a pen-and-paper puzzle with 3-dimensional objects. Or you might like the idea of taking a 3D puzzle and drawing it.
