Gotta love those optimistic AP problems

So, doing a practice AP for math homework, I come across the following question:

The spread of a disease in a population is modeled by the differential equation P'(t)=.03P(t)(30-P(t)) where P≤30 is measured in thousands of people. (Presumably there are only 30,000 people in the population.)
Part a asks you to find the general solution, part b to find the specific solution where P(0)=5.

Now part c says "Estimate how many people will eventually have the disease.", that is, find lim[t→∞] P(t). Hm... solve solve solve, crunch crunch crunch, use your common sense and then verify with L'Hopital... (You can do the problem yourself if for whatever perverse reason you actually like this sort of thing...) and we get, lim[t→∞] P(t)=30, that is, "eventually", the entire population will have the disease. Oh goody.

And here they say you can't mention death in school anymore.

In a short break from my math homework

I've changed the journal's subtitle. It now reads, "Just a boy trying to make nonsense out of his life." I think this is much better than any I've had previously, but then again, I can't really remember what subtitles I've had previously.

Happy birthday, mom!... not that you're reading this. At least I hope you're not.

"You *realized* that? Or Ashley and I *told* you?"
"You told me, I was too dumb to listen, and then I realized it myself several weeks later."

Hmph. Apparently GM has a new tradition of closing early. Meh.

Tupperw*re Boy[0] was away in Las Vegas at a convention of, as it was put, other T*pperware Boys, and so I got, or rather, had, to be his replacement. Not that I was a very good replacement for him - not that I think anybody really *wanted* a good replacement for him, though. :D

Nick has this Go set that came with these rules written in horrible, horrible Engrish. Unfortunately I don't remember any exact quotes from it.

Oh, and while I was there, I bought Munchkin 2. Would have gotten Munchkin 3 if I had actually thought to bring money other than what was left over from before... hey, why *did* I have money with me before? Oh well.

ADDENDUM: Oh, and after Nick left, I went and made a chart of the probability of not wimping out (or Supernovaing, for that matter) based on how many dice are rolled and whether or not the black die is rolled.

Now to go do math homework.

[0]Well, it's a distinctive name, and I remember what happened last time I allowed him to find jonpin[3]. Well, actually, no, I don't, but I'm sure it was bad. Well, come to think of it, I wasn't actually hurt, but I'm pretty sure I was threatened, and that's generally enough for me.
[3]Wait, since when do I call Jon "jonpin"? It sounds kind of awkward now that I read back over it, but I'll leave it in, just because otherwise I'd have to get rid of this footnote.
