Tsk. A current radio spot gives the web address “wachovia dot com backslash new”.
Meanwhile, what’s new with me?
I’m reading Coxeter’s Non-Euclidean Geometry in the hope that it will give me the stuff I’ve sought in vain in other books: the actual formulae for coordinate transforms under the various isometries, rather than useless taunts like “a matrix with such-and-such properties” (which I don’t know how to recognize let alone generate). But it uses so many cryptic notations that I’m afraid I won’t understand the formulae if they do show up. Exercises would help. [Later: No such luck. It barely touches on H3 at all.]
My car’s starter burned itself out. Luckily this happened at home on my day off; a few hours later, all was well. My housemate pointed out that my last bit of car trouble (a dead battery) also happened at home. What a well-behaved car!
Pillow, the junior cat, has been smelling of smoke lately; and we don’t know where he’s pooping. It would seem he has found a second home, though that’s odd since he consistently flees human strangers. Perhaps he was seduced with catnip.
Tonight my car’s alternator apparently died on the way home. I nervously watched the instrument lights get dimmer and dimmer. Finally came to a stop about thirty yards from my own parking space!
Next morning: it wasn’t the alternator itself: the alternator belt, replaced the day before, was loose.
In geometry, I eventually found what I wanted in Euclidean and non-Euclidean geometry: An analytic approach by Patrick J. Ryan (Cambridge University Press, 1986).
Today I heard another radio spot that misused “backslash” (at least twice).
