I’m looking for the last topics for the Little 2021 Mathematics A-to-Z

I’m approaching the end of this year’s little Mathematics A-to-Z. The project’s been smaller, as I’d hoped, although I’m not sure I managed to make it any less hard on myself. Still, I’m glad to be doing it and glad to have the suggestions of you kind readers for topics. This quartet should wrap up the year, and the project.

So please let me know of any topics you’d like to see me try taking on. The topic should be anything mathematics-related, although I tend to take a broad view of mathematics-related. (I’m also open to biographical sketches.) To suggest something, please, say so in a comment. If you do, please also let me know about any projects you have — blogs, YouTube channels, real-world projects — that I should mention at the top of that essay.

I am happy to revisit a subject I think I have more to write about, so don’t be shy about suggesting those. Past essays for these letters include:
