If I may speak up for my own writing here, I've begun my mathematics blog's annual glossary project. In line with my very worn, battered spirits, it's a smaller one than usual. To start the Little 2021 Mathematics A-to-Z, the letter ... M, for Multiplication.

My second essay for the Little 2021 Mathematics A-to-Z was a companion to multiplication ... A, for Addition.

My third essay for the Little 2021 Mathematics A-to-Z went to the Torus, and as you'd expect, board game design.

And my Little 2021 Mathematics A-to-Z continues through the word, with H for Hyperbola.

I've let myself fall behind on my writing again. For the next letter in the Mathematics A-to-Z, 'E', I wrote about Embedding:

For the second 'A' in the Mathematics A-to-Z this year, I try to explain Analysis in 1500 words. There's details omitted.

Last week's essay, the second 'T' in Mathematics A-to-Z, was about the Triangle:

For the letter 'I' in my Mathematics A-to-Z, it's the Inverse:

And I'm appealing for suggestions for the last couple topics seen as I hope not to miss deadline for the letter 'C' this week:
And for the letter 'C', I wrote about 'convex':

I'm falling behind on myself again. For the letter 'S', and finishing off my spelling of the word 'Mathematics', it's Subtraction:

Emblematic of how much I'm falling behind on things: here's the latest essay in my Little 2021 Mathematics A-to-Z, for a third letter A, Atlas:
https://nebusresearch.wordpress.com/2021/12/15/my-little-2021-mathematics-a-to-z-atlas/
The project's on a hiatus right now while I deal with ... just ... you know ... *everything*.
I did finally resume the Little 2021 Mathematics A-to-Z, after a pause necessitated by life being all too much. For the third-to-last letter, it's another T, Tangent Space:
https://nebusresearch.wordpress.com/2022/02/23/my-little-2021-mathematics-a-to-z-tangent-space/
And for the penultimate letter of this small yet difficult project, O, for Ordinary Differential Equations:
I at last reached the end of my 2021 A-to-Z, with Zorn's Lemma:
https://nebusresearch.wordpress.com/2022/03/09/my-little-2021-mathematics-a-to-z-zorns-lemma/
I can't say what I'll do next, except it's probably sharing Pi Day themed comic strips.
And for the second letter 'M' in my Little Mathematics A-to-Z, here's 'Monte Carlo':
