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*.

And in my A-to-Z ... I got asked to explain linear programming. I can give it a try at least.

Continuing through the alphabet: the Koenigsberg Bridge Problem.

Is it possible to write about Julia Sets without including any pictures? Of course. Is it wise? This is a hard question.

I took a couple pages from an analysis book for the next of my A-to-Z essays: the Infimum.

The letter H for this season's A-to-Z gave me a chance to dip into mathematical physics. It's the Hamiltonian.

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.

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.

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.

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.

Cows? On *our* Internet? It's more likely than you think.

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.

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.

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.

A friend mentioned how he wished he knew of a pop-mathematics essay about the Ricci Tensor. So he could understand what the Ricci Tensor is about and why we need it.

This reminded me I *had* written a pop-mathematics essay about the Ricci Tensor. Also that like a third of the essay is me admitting I'm not sure I understand what the Ricci Tensor is *about* or why we need it.

I wrote a bit about a bisection of a triangle's area which, when I read it, made me lower the book and call it a rotten liar. (It wasn't lying.) The thing might be old hat to you, but it startled *me*.

(I have a follow-up post to it scheduled to post later today.)

I should take my chance at #introductions

I'm a mathematics PhD. Unemployed by academia, but at least working in Geographic Information Services. My work was in inviscid fluids and Monte Carlo methods, but I keep thinking I know knot theory better than I do.

is my pop-mathematics blog. Its big features are essays based on topics raised by comic strips, and a roughly annual A-To-Z feature describing one mathematics term for each letter.
