I happend to mention to my father that my car was due for its 70,000-mile checkup, and that bunny_hugger's car had needed a CV joint replaced. This launched him into a long description of pretty much everything that could possibly be checked on a car and how I should have it checked. I was able to talk him down to promising that I would ask the dealer to look at my car's CV cover joints, which I'm willing to believe are a thing, to make sure they're in good order. I suspect my father hasn't got enough things to worry him based on how enthusiastically he was going over every detail of one of the minor service checkups on my car.
I can't help thinking I fluster the service department by asking for an appointment for a mid-afternoon weekday service, but they go on saying it's fine that I make them. And I did ask about the CV cover joints. The only real car issue appeared to be the rear wheel alignment. I'd had a suspicion about the alignment, based mostly on how the roads around town are a long series of tactically arranged potholes more than they are roads. They talked me into geting that fixed, though, so the week was that bit more expensive.
The next day, which was a good bit colder, my tire pressure warning light came on. A couple dozen miles of driving and the car decided the pressure was fine after all, though. There's some temperature ranges that make the pressure warning light over-sensitive, because really, what carmaker could imagine a car being driven in 40-degree weather?
Trivia: Sadi Carnot, pioneer of the modern theory of thermodynamics, died in August 1832 at Charenton, a hospital for the insane. Carnot had cholera, and the hospital was taking cholera patients in the hopes of isolating them from patients at other, overcrowded hospitals.

PS: Reading the Comics, April 20, 2015: History of Mathematics Edition, which maybe overstates how much history-of-mathematics content is in the comic strips discussed here. Anyway, fifth mathematics post since the last roundup of those.
