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

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:

And for the second letter 'M' in my Little Mathematics A-to-Z, here's 'Monte Carlo':

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

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

@jsiehler I had not and now I am intrigued!
