(The oral syringe is for a cough syrup the rabbit takes as possible treatment for allergies. It turns out rabbit allergies are an under-explored part of veterinary medicine. In the second picture she's chinning the empty syringe because she really likes it and wants everyone to know that it's hers.)
Nearing the end of the 2020 A-to-Z! For the letter W, the Wronskian.
Also there's much I did not know about Józef Hoëne-Wroński and still don't.
For the letter V, my 2020 A-to-Z comes to the subject of Velocity:
The Replay Foundation, my employer, announced their liquidation today. This means no more Pinburgh. It also means I'm Officially out of a job for the forseeable, so if y'all wouldn't mind boosting a link to my other source of income Improbable Island, that'd be just super.
It's a silly online game and it doesn't pay as much as fixing pinball machines but heck it's what I've got right now, and this winter's probably gonna be a hairy one.
I apologize for slipping behind on this again. November's been a heck of a month.
For the 2020 A-to-Z the letter 'U' brought me to Unitary Matrixes:
It's a little rough because the first half of last week was not a good one for my focus.
When I got to the letter T for my 2020 Mathematics A-to-Z glossary, I picked Tiling, always a fun subject:
After it posted I discovered I had already written about it for my 2018 A-to-Z, so rf. It's cute, though, comparing what parts I figured were more important and what I could gloss over in the unintentional rewrite:
Join me in 2022 when I do tiling *again* for no good reason.
Someone asked me to explain Statistics for the letter S. I got political, because the subject *is*.
For the letter R, this year, I try to explain something about Renormalization. Difficulty level: I do not open with quantum electrodynamics.
For the letter Q, in this year's A-to-Z, I wrote about Quadratic Forms and finally, after decades, thought about what it is makes something a 'form'.
And then I failed to follow up! Back on the A-to-Z, my next topic was Permutation.
USpol humor (vague)
Don't know why this Peanuts comic from 1964 is on my mind.
I'm not sure what the white rabbit there is doing with her foreleg but I'm impressed by it.
I have a special event to announce! I was fortunate enough to host the 141st edition of the Playful Math Education Blog Carnival, featuring many links to mathematics fun, educational, philosophical, or at least accompanied by amusement park pictures:
I read comic strips and write about the mathematics in them. He/him. Black Lives Matter.
