And while I'm still a bit over a week out of starting my A-to-Z essays, I am also looking for letters 'B' and 'C'. Here's a link for requests, and also offering the lists of essays I've written for those letters in the past.
Thanks again for any thoughts you have.
Our pet rabbit sitting up and folding over like a rag doll, as in that second picture, is some idiosyncratic thing she's figured out as a way to groom her feet and tail. We've never seen another rabbit do that and we have no idea how she figured how to do it.
Last year I did an A-to-Z glossary, writing one essay for each letter of the alphabet. I'm starting another one of them, and am looking for topic suggestions.
Here's a link for the letter A, and a list of the essays that I've written for 'A' in past years.
Thanks for any thoughts you have.

Our pet rabbit, who has cataracts, got her annual checkup for those today. They took her in the carrier from our car so we couldn't go in with her, and we assume she was cross that we weren't there to pet her head through the ordeal. Also that we had her in the pet carrier.
The happy news is the cataracts remain unchanged, the one in her right eye too small to impair her vision, and we can go on giving her the eyedrops that she tolerates.
Reading Glen van Brummelen's _Heavenly Mathematics: The Forgotten Art of Spherical Trigonometry_:
"We begin with the theorem that is named after Menelaus today, a statement from plane geometry that we shall extend to the sphere [ ... ] Curiously, Menelaus himself does not prove the planar statement, so he must have thought his readers already knew it."
I know Stigler's Law of Eponymy but this is getting ridiculous.
Just wanted to mention one of my all-time favorite The Far Side strips is among today's reprints.
And now the end of my 2019 A to Z, and my fitful self-introduction to Mathstodon: Zeno's Paradoxes. I only get about halfway through them. This may be a joke, but it's not one I made deliberately.
The suggestion I had for the letter Y was a game. It's one that I like, without having ever played. I just like the theory of it.
For the letter 'X', an A-to-Z has to take a loose interpretation of things. For example, by going to Greek: the Chi-Squared test.
I was asked to say something about Wallis Products. This let me discover just how the heck Wallis could have discovered such a thing. So here goes:
The letter V let me get into some of my peculiar favorite things: obscure trigonometric functions and numerical convenience. Here's some words about the Versine.
For the letter U, the most interesting suggestion was for Unitizing. It's one of those things I had not consciously noticed was a thing, which made for an interesting essay challenge.
For the letter T, I was asked to say something about Taylor Series. This fits well with my desire to insist that everything in mathematics is polynomials.
I read comic strips and write about the mathematics in them. He/him
