Me-Status:

I got out of the house again for a couple hours. Picked up antacids and a few other neccesaries. Mailed the note from the clinic to the jury commissioner. Saw a bumper sticker that said, "Wake me in 2008 ... if anyone's still alive," which bothered me a bit because a) most of us will be alive but will we still be free? And b) because we need folks awake and fighting the whole time if 2009 is going to be any better. But the same car als had a bumper sticker that said, "Jesus was my copilot, but we crashed in the mountains and I had to eat him to survive," which a) would've caused me to splorf my soda if I'd been drinking one at the time, and b) raises entertaining thoughts about communion. (Hmm. If a plane carrying a cargo of communion wafers crashed ...)

Alas, headache and sound hypersensitivity steadily increased much of the time I was out. But at least I gout a couple things done and got home before it was too bad to drive.

Cat-Status:

Lethally adorable -- I am ded of teh cute.

House-Status:

According to the automated phone inquiry system that it took me THREE DAYS OF BUSY SIGNALS to get through to (!), Mom is up to date on the property tax and the house isn't headed to tax-auction for a $20 discrepancy after all. (Yah, three days of busy signals and redialing -- Monday, Wednesday, and today, I didn't try much Tuesday or yesterday -- to reach the machine. Methinks my city hasn't allocated enough resources to that service. But it worked pretty smoothly once I got through.)

Random not-status:

I've been reading drug inserts, and noting the familiar, "$(DRUG) is a white crystalline powder with a bitter taste." Gee, how many drugs is that not true of? OTOH, I'm also seeing something unfamiliar; black isosceles triangles and black-and-white banded isosceles triangles, pointing from O atoms to a benzene ring. How do I Google for that? (Next best thing: mutter about it here and have somebody who took orgo explain it to me in a comment, eh? (hint))

Google does inform me that if I'm looking for isosceles triangles, I can get them on eBay, in any case. (Okay, eBay is telling me that by way of Google's context-advertising thingumie. Which I understand Google doesn't think is the most appropriate use of that feature.)

And now to rest up for tonight's planned attack on my mailbox.

Here from metaquotes, as I was wondering what on earth isosceles triangles had to do with drug inserts. I believe what you're seeing is a common way of denoting the orientation of the atoms hanging off the benzene ring. Anything that's attached via a simple straight line is in the plane of the page. Things with a solid black triangle are coming out the front, i.e., towards you as you look at the molecule. The ones that are denoted by the banded triangles are going out the back, i.e., away from you. In organic chemistry, the orientation is everything. For instance, one orientation of thalidomide is beneficial (prevents morning sickness); the other is very much not (causes extremely severe birth defects).

According to Wikipedia, this particular projection is called the Natta projection (http://en.wikipedia.org/wiki/Natta_projection). Other common ones include the Newman projection (http://en.wikipedia.org/wiki/Newman_projection) and the Fischer projection (http://en.wikipedia.org/wiki/Fischer_projection).

Ah! Thank you, and that makes a great deal of sense. I knew that isomers, even mere stereoisomers, mattered in biology, but it hadn't occurred to me that I was looking at a projection -- I thought there was maybe some new kind of bond I hadn't learned about in 11th grade or something. I'm relieved. Now that it's been explained, it seems nearly obvious (and, looking at the diagram of Topamax again, quite readable once one knows -- I can actually convince my brain to reinterpret the diagram as a three-dimensional image if I defocus my eyes a smidgen, which I didn't expect to happen so quickly).

Now off to Wikipedia to familiarize myself with the others so they won't seem so mysterious when I run across them.

Again, thanks.
