Just passed 50K total views worldwide on my math video animations channel! Root Spiral of Theodorus is the most popular with over 18K views. Leading countries (currently) are India (53%), USA (18%), and UAE (13%).
Until a few years ago, I didn’t know Theodorus from brontosaurus. But then, somehow, I heard about it, and thought it could be a simple and beautiful way for kids (and other people) to start to get the hang of square roots as length.
I thought I could probably do an animation of it in PowerPoint. I did, and after a bit of fussing, Root Spiral of Theodorus was the result.
It’s been quite popular: over 18,000 views since I uploaded it last April. If you google “root spiral of theodorus”, it comes up #2 out of 26,300 results, right after Wikipedia.
If you like this one enough to use with your students, as with all my other animations, you can download the PowerPoint file from my “Animations” folder and have a version you can teach with, turning off the timed settings and advancing it slide by slide to suit your purposes, or even modify the content to according to your whim or needs. I’d like to get credit, naturally, but if you’d prefer simply stealing it, oh well….
