New month, new process video for the Talking Maths in Public animation generation collaboration. The challenge was to animate polyhedral nets folding up. I show one way in manim. Is this helpful to learn from?

Sequence from @tedgar7.bsky.social!

Entries are light-colored if and only if there are no 'carries' that occur when adding k and n-k in base 6 using the traditional addition algorithm.

You still have two weeks to submit your video for this month's TMiP Animation Generation Collaboration! April's prompt is to create an animation of the net of a polyhedron opening and closing, and show your process. It can be any polyhedron you like!

Probably the most epic proof of Ptolemy's theorem you will ever see:

New Math Horizons is out now and I have a short article about taking the Fitch Cheney card trick down to two cards. It’s pretty hard to perform but there is cool math involved :

Last year I made this April math calendar with one “April fool” math concept for each day:

Tried a new type of video as part of the Talking Maths in Public animation generation collaboration. The challenge was to animate classic circle and sine wave. I show one way in manim. Is this helpful to learn from?

It’s already Pi day in some parts of the world. Here’s a cool visualization of the Madhava-Gregory-Leibniz formula for pi/4 due to Viggo Brun (and written about by Mitsuo Kobayashi). Hope you like it and share with all your math enthusiast friends!
