In October, Simon’s videos were featured on the Global Math Project website!

The bulk are his latest three videos with detailed proofs of pile-splitting magic:

In this video, I will show a pile splitting trick, and show a really elegant proof for it. So elegant, in fact, that you can extend it to a lot of other pile splitting tricks!

Also Simon’s recent counting-in-binary project got featured, an interactive Napier’s Checkerboard simulation he programmed in p5.js:

I’ve figured out how to do square-roots in binary on Napier’s Checkerboard!

Simon had already explained doing square roots in binary on paper, see our earlier blog post.
