On my mathematics blog I'm trying an A to Z run, writing one essay for some mathematical topic for each letter of the (English) alphabet. The start of the series was A, for abacus, per a reader request.
I apologize for the delay in following up. My second A to Z essay, on Buffon's Needle, is up at https://nebusresearch.wordpress.com/2019/09/05/my-2019-mathematics-a-to-z-buffons-needle/
This one is also based on a reader request, from Peter Mander of the https://carnotcycle.wordpress.com thermodynamics blog.
The third of my A to Z essays came out Tuesday: Category Theory, as explained by a person who's just knowledgeable enough of the subject to know he shouldn't be writing an essay about category theory.
The fourth topic asked for in my A-to-Z this year was Differential Equations. I had some fun thinking about what they are and why they're interesting.
I got asked to say something about encryption schemes for the A-to-Z and did my best to say things that weren't too wrong.
My series got up to the letter F and, by several requests, Fourier series. My unstated challenge in this: see how far I could go without writing 'sine' or 'cosine' at all.
For the letter G: Green's Function. Also, I learn how much I don't know the actual rules about what LaTeX you can do in a free Wordpress blog.
I took a couple pages from an analysis book for the next of my A-to-Z essays: the Infimum.
Is it possible to write about Julia Sets without including any pictures? Of course. Is it wise? This is a hard question.
Continuing through the alphabet: the Koenigsberg Bridge Problem.
And in my A-to-Z ... I got asked to explain linear programming. I can give it a try at least.
The letter 'M' brought my A-to-Z for the year to martingales, because the other request was the Mittag-Leffler function and I couldn't think of any way to explain *that*.
