Long-time readers may have felt like something’s missing from my 2019 writing around here. It is an A To Z. This is one of my traditions, to write essays explaining some mathematical concept or related term, one for each letter of the alphabet. I’ve traditionally taken nominations from readers for this, and I plan to do so again.
I’m not taking nominations just yet. I’d like people to have the chance to think about stuff they’d like to see explained. This is how we get things like people asking me what the Ricci tensor is and why we need it. I’m still not perfectly sure I know why we need it, but the essay is out there, so that’s something.
Anyway I have banner art commissioned, again from Thomas K Dye of the Projection Edge and Newshounds web comics, and whose Patreon is here. When I have that I’ll open up at least part of the alphabet to subject nominations.
Also I continue to have the problem where Twitter won’t load on my web browser, Safari. I’m getting close to desperate measures, such as restarting my computer or trying to load it on a different web browser. If you wonder why I am even more quiet on Twitter than usual, this is one reason why.
