Well, I bombed out on discussing my research on polygons. Let's see if I can do better with my research on prisms.

The specific topic I'm investigating is closed geodesics on rectangular prisms. Before I can talk about that, I need to discuss geodesics in general; and before I can do that, I need to talk about the notion of curvature. Follow if you dare... )

1. Back in the early '70s, one of the San Diego radio stations used a bit from "Time in a Bottle" in its advertising. Forty years later, the last six notes of the intro to that song still evoke the jingle. "Might-y K-F-M-B". Drives me nuts.

2. Today, playing fetch with Buster and his squeaky bone, I went for an underhand toss just as he leaped in front of me. Caught him square in the nose; the bone bounced off in some random direction. He yelped, but it only took a few seconds of consolation before he was revved up again. I retrieved the bone and tossed it, and the game resumed.

3. We didn't get the threatened snow last night, but it's been pretty cold - high in the low 40s F. Thankfully, it's supposed to warm up into the high 40s tomorrow....

4. I'm rereading American Gods, and just reached the bit where Shadow stops in Cairo, Illinois to shelter with a couple of Egyptian gods-in-exile. They go off on a discussion of all the contact there was between Old World and New, even millennia before Columbus. I lost my WSoD there, I'm afraid; reading 1493 has left me all too aware of the unlikelihood of sustained contact such as is described. Oh, well....

5. I'm beginning work on a revamp of my financial-records software. My experience with the library database has suggested a number of improvements, including a crippled but still serviceable implementation of tree-structure for types of expenses. I haven't tried to write the macros yet, but I think I can make it work.

6. It's time to think about this year's Thanksgiving cookfest. I'm leaning towards making a batch of boeuf bourguignon, with maybe another home-made apple pie for dessert.
