I recently learned about tagging livejournal posts - attaching keywords descriptive of the contents. This struck me as a good idea, so I changed over to Style 2 (which allows tagging) and went through my archived posts, tagging them as seemed appropriate. Fortunately, I've only been LJing for a year and a half, so this wasn't too lengthy a task. I'm not entirely satisfied with the set of tags I'm using, so I may make another pass-through sometime soon to adjust things.
Who cares?
"I told you that so I could tell you this." I noticed that it's been almost six months since my last post on mathematics. As it happens, the material I covered in my geometry class Thursday night is kind of neat and fairly self-contained, so I thought I'd recap it on LJ. Basically, it involves taking a close look at the differences and similarities between Euclidean geometry and hyperbolic (Bolyai-Lobachevsky) geometry. (They are more closely related to each other than either is to the third option, elliptic [Riemannian] geometry.) I'll put most of it under cuts, of course; it'll probably take three or four posts.
