OhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgodOhgod...

I am so screwed.

I just took the practice algebra test, and I got 41%. Functions and graphing kicked my butt to the door and into the gutter. (I shouldn't count the questions on complex numbers as I haven't reviewed that material yet, but needless to say that added to my miserable outcome.)

The worst bit is that some of the answers really confuse me. Like, why is 2+x+y a factor of 4-(x+y)^2? I do not understand that. At all.

And how does (3(-1)^n-1)/2^n create the geometric sequence 3/2, -3/4, 3/8? Got it. Never mind.

(I also really, really need to review sequencing of all ilks. Only learned sigma's meaning today. Yikes.)

I am so, so screwed.

Which means I have tons of stuff to do.

Homework, cooking, cleaning... And somewhere in there, I need to find time to nap. Been shorting myself on sleep this week, and I would rather not waste the weekend catching up like I did last weekend.

Question is, do I try for the nap first, or at some vague point in the future?

Decisions, decisions...

And for you math/science whizzes out there, is there a formula for calculating the acceleration of a heating process? And if so, how much data would one need to use it? And would you need the temperature of the heat applied or just data points?

I ask because I would like to figure out how long it takes for 70 degree cream to come up to 100 degrees from the heat of a 40 watt bulb. I know it takes longer to warm it up the first fifteen degrees than the second, and that heating is a self-propagating process, but I'm also sure there's a way to calculate a reasonable estimate of the rate it does accelerate.

*shrugs* Yes, this is more idle curiosity than anything.

Anyway, I'm gonna go make my second cup of tea and start my day. Homework will be first, I think. That way, when I tire myself out doing the cleaning, I can read for pleasure without any guilt!

Cheers!

It's spitting snow. Spitting. Snow!

A snow day was called because of the few meager inches of snow on the ground and the false promise of more to come. I wonder when the last day of school will be now. June 27?

(I think it's really stupid of schools in NEW ENGLAND to not pad the schedule with the expectation of at least a week of snow days. Especially if they call them over a measly inch or two of the white shit. It's... parsimonious. It's also really disrespectful of the teachers.

"Oh, we can't have you work less than 180 days! Because your job is so cushy as it is!")

If there's an exceptional winter and there are more than 7 or 10 snow days, then yeah, make-up days should be added. But to need to replace every. single. day is just mean spirited.

Not that Page would be in school today even if there were school. His cough is now at the juicy stage. Ew.


But, he's amusing himself by making up math problems for me to solve. An example?

___ + ____ - ____ + ____ + ____ - (___) + ____ + ____ - ____ + ____ + ____ + (____) + ____ - ____ - ____ - ____ + ____ = 5,141,100,000,000,000

The solution to the last one he gave me was 2.21 x 10^21. Written out. I had to explain to him that the trickiness of the problem does not necessarily increase with the number of zeroes, though I'll admit they did get a little trickier to fill in when he added subtraction to the problems. And way more amusing.


Meanwhile, I need to go pay bills and send out my application (and very large check) for a local, organic CSA. I did the math and our food bill will pretty much end up even steven, if not actually a few dollars less per week. I'll still grow our favorite veggies in the back, like kale, broccoli, cucumbers and napa cabbage, but this will augment our diet nicely.

I'm just bummed that the 3 hours a month work memberships were filled. I was looking forward to it. Ach well. Probably better this way.


So off I go. *bug sigh* (<--- rather appropriate typo. I'll leave it.)

First, go look at the Astronomy Picture of the Day (it's actually a timelapse video): http://apod.nasa.gov/apod/


Nothing undercuts a guided relaxation gig like remembering near the end that you have an appointment in two minutes and you don't have the car. On the plus side, as I was calling Geoff for the car, I looked at the calendar and found the appointment (my placement test) is tomorrow, not today. Phew. (Downside, of course, is that all the relaxation was erased in that moment of realization. Plus side: I wasn't panicked.)


Geoff's sick. He's at work, but he's developing a chest thing which I really hope won't be bronchitis. He's prone to it. He hasn't had it in... gosh, ten years, but before that, it was a horrible yearly occurrence. (Maybe I'm good for something after all! ;-) No coughing yet, so hopefully it'll peter out, but... :-(


The robins have come back. Can hear them chirping away, even though it is bitter out. Beautiful, with the sun shining and bright, blue skies, but the wind feels arctic. And, of course, it is constantly breezy.


Made some Chinese chicken stock yesterday, and boy did it smell good. I still need to strain it, but seeing as there isn't all the detritus of western stock, it should be a small task.


I need to dust. Fortunately, there aren't any vampires around to dust, thereby creating more dust. Small consolation, though. (Season 4 Buffy is the best yet. God, it's good to laugh!)


Last day of algebra and math study, and then I can switch to writing and painting. I'm looking forward to doing both.


ETA: Oh, and this is going to sound very odd, but god, I love the smell of kimchi in the morning. I am so happy to have some in the house again!

This one is from the book's final exam:

y = -2x
3x + -4y = 10

a. (4,-2)
b. (-2,4)
c. (-4,2)
d. (2,-4)

And please, do show your work.

*growls*

There were six exam questions they got wrong. Most of them involved misused negatives, like the problem shown above.

Not counting those six (most of which I guessed their "correct" answer correctly), I only got one wrong (maybe. Looking it over again, I'm not so sure... 5x-5<20; is it x>5 or x<5? Book says x<5, I said x>5). I think I can safely move onto algebra II/trigonometry now.

Heeeeeeeeeeeeen!

Today )

And have I mentioned lately how Spring is nearly here? I've told Page that we'll be walking to school again starting next week. All but one pile of south-facing ice is gone from the sidewalks, and that pile should be gone after this weekend of 50+F weather!

Now is the time to really get my garden plan in gear and price out everything we're going to need to get it looking good. I'm actually really excited about this growing season. It'll be expensive and loads of hard work, but it will make this place so much more my home, as well as improve the neighborhood. And as long as front-end loaders and men with big stompy boots stay off my ferns and heucheras, I will be happy.

Now I'm off to look at pictures of carefully planned hills and dales. La!

So, I went to the library today to pick up some algebra course books that might actually be helpful. So far, the one I'm using is very helpful. It reminds me that I am not stupid, and that yes, algebra is actually fun.

However...

Can you solve this set of equations?

x = 2y
4x + y = 12

My answer differs from the book's, and I have absolutely no idea how the book's answer came to be had. )

I'm not overly concerned about this, seeing as I got every other question I tried right and I understand the methodology. I'm just curious if I'm missing some process for this example or if the book'a author/editor chose a(nother) shady example.

Ach well, it's late. I'll probably look at this problem in the morning and it'll be so obvious I'll cringe and delete this post to hide my shame. But in the meantime, can you explain it?

(I say as if I haven't already taken the last few days off...)

A number of things have brought me down, and I woke up this morning knowing that I need to make yogurt, I need to go to church and I need to do laundry, preferably all in that order.

However, I also knew that I am not going to do any of those tasks. I am tired. Mentally, physically and emotionally. Wrung out. I don't have much good reason to be (nothing extraordinary, anyway), but I am, and I better respect that if I don't want to plunge into a depression which will cut the legs I've finally developed out from under me. (I asked Geoff last night if he thought I was getting depressed - him being a depressive as well, he knows the signs - and he's as unsure as I am, what with all the viruses and tragedies going around. I have started taking vitamin D again, just in case it is depression.)

I might work on my algebra today, as it's a matter of pride, but I will work on it more intelligently so as to avoid the frustration that's been growing every day; i.e. I will look to learn the lessons presented in the course elsewhere, because the professor of the course I'm taking can't teach this course worth shit. I've already explored the internet for the current frustration and found a perfectly diagrammed explanation that cleared up all of the issues I was having with that specific process. So ner.

*gives finger to course instructor*
*but realizes I'm getting what I'm paying for*


On the bright side, I managed to make a pair of pants for Page to wear to karate yesterday morning (that is, the lesson and the construction all took place yesterday morning), and he enjoyed his lesson. Whatever bug he had on Friday, he is fully recovered from it, as he's been literally bouncing around and throwing his arms around me with enthusiastic "I love you!"s since Friday afternoon. And he's been unusually compliant, actually doing things we ask of him without waging a huge battle about it. And helping without being asked. Most unusual, but lovely.

Geoff and I also ordered our glasses yesterday. Ouch. But I think it'll be well worth it. I found an eye prescription from 2006, and it seems my vision has got a full point worse in the last five years (going from +1.75 - +2.75 in one eye, the other eye having comparable deterioration). So, yeah, no wonder I've been tired lately. I've been putting all my limited energy into seeing.

The frames I ended up getting are not any of the ones I listed, amusingly. When we were trying on glasses, I veered into the (unmarked) children's section and lo and behold, yes, there, that one, yes, the full rimmed, dark copper one, suited my face far better than the half-rimmed light copper lovely I liked before. (Of course it was more expensive, as well... grr.) But I'm now looking forward to getting them back and being able to see properly again.


And to wrap up, I'll do yesterday's (appropriate for today) sin:

Sloth )

Went to the eyeballogist today, and the drops have just worn off enough to be able to read less than 24 type fonts. Though things are still pretty blurry.

He told me off, in the kindest of terms, for not having switched out my glasses for the last *mumble* years, so it's looking like I will be getting new glasses very soon. Geoff should, as well. (When it rains, it pours?)

But, this does explain why I've found reading books so tiring lately. It also might explain the current bout of conjunctivitis I've contracted got. Reading off-screen books used to do that to me quite a bit. And I'll rationalize the price of new glasses as cheaper than an ereader, and far more useful.


This morning was rather a disappointment as it turned out I needed all of Babe's school time (from when I got going, which, granted, was not that early) to do the next lesson of algebra. I'm finding this course frustrating because a) the tests cover material not covered in the lesson, b) the links given to explain the lessons are alternately too basic or too advanced for the topics covered, and c) I'm experiencing a resurgence of math-related anxiety.

Math was the only subject in school that would consistently tie my stomach into knots, and not just at test time. I'm very disappointed that it still does it, especially as I seem to have lost my instinctual grasp of it. Not understanding some of the basic concepts (right away) is... humiliating. This is pretty easy stuff, so I feel stupid when I don't get it.

To add injury to insult, I made some dumb mistakes in both the homework and the test today. I expect I passed both, but... bah.

Not that this course really matters. This course is only to get me reacquainted with the subject enough to not need to spend time and money on remedial math when I go back to school. Its worth is showing me where my weak areas are. Too bad it seems that they're all weak areas...

But not all is lost. I have three weeks to study hard and get a better grasp on this stuff. A good enough grasp to be able to take calculus and not drown. I think it's probably doable, especially with Geoff on hand every night to help. I just wish it weren't so difficult to restart the brain.

However, this does tell me that I am right in that I have become dumber over the last few years, and that I am making the right decision in going back to school now. I can still salvage a fair amount of gray matter if I get it going now before sclerosis sets in.

ETA: Heh. Got my scores back and while I did miss one on the test (on a question I really wasn't sure about), I got 100% on my assignment. Even though I did goof part of one answer. *shrugs*

It's still not coming easily, and my shitty memory is not helping.
