Relief and sadness

I express mailed my REU application yesterday, the essay nearly killed me (oh grad school apps are going to be awesome).

I passed evil Moore method class. Granted it was a C, but I passed nonetheless and it will average out with my A in Abstract Algebra so it's not too bad. (And my A in Thermal Physics. Granted those grades haven't been posted, but unless I got 0's on my finals, which I can guarantee I did not get, I should be getting A's.)

When I (flippantly) mentioned that my math geek could teach in Houston (I *really* like the program at Rice, thanks Rebecca! but no matter where I go it will not be in this state or (hopefully) anywhere west of the Mississippi) his only response was that his scholarship is dependent upon him teaching in state for the next 3 or 5 years (he wasn't sure which). But he did say that the program sounded really good and we agree that I should go if I get accepted. It just makes me really really sad. He wasn't averse to the idea of moving (and he does have a job which is highly portable: high school math teacher), he just has to be here for awhile. Oh well, that is in the future, but it's still a sobering thought and one that doesn't exactly fill me with warm fuzzies.

At least I get to read and it's nice to not have classes because I get to meet up with my math geek everyday after he finishes school for coffee or an early dinner. (Since my afternoon spring break schedule consists of me buying a New York Times, going to my favourite coffee shop, yelling at the paper and talking to my friends I have neglected because of school.)

Pi day!

SO today at 1:59 (3/14 1:59 haha) that math department showed this HI-larious video called The Great Pi/e Debate. (I would LOVE to have Garrity as one of my prof's. He's hysterical! I love it! I do like the prof's that get all crazy and yell. Branco does that all the time especially with proofs, it's highly amusing.)

I also found this:

e vs pi!

"Ladies and Gentlemen, in the one corner we have pi. First written about by Euclid, pi is the ratio of the circumference of any circle to its diameter. Pi's been baffling people for millennia with its ability to just keep going without end. And here's the thing folks, it's the same for ALL circles! you can have a circle so small you can't even see it, and it'll be pi times as big around as it is across. And then you can draw a circle around your house, and same thing. If you had a circle that went all the way around the universe, people, its circumference would be pi times its diameter."

"And in the other corner, the scrappy young e! e was studied by the mathemetician Euler in the 1700s, e certainly doesn't have as much experience as pi, and at a measly 2.71828, certainly gives up a weight advantage to pi's 3.14159, but don't let that fool you folks...e can go on just as bafflingly long as pi, and represents the limit as n approaches infinity of (1 + 1/n)n. It is the base for the natural logarithm! The graph of f(x)=ex has a slope of exactly ex at any value of x! That's right folks, it derives its OWN tangent!"

"AND WITH THAT, e takes an early jab at pi, which reels back but quickly multiplies itself by i and raises e to...-1! Oh, e is hurting people but quickly re-derives itself from itself showing pi the versatility of truly interdimensional mathematics..., pi confined merely to the cartesian plane is quickly lost in its meager foray into Complex mathematics, and tries to re-aquire geometric footing..."

"But Pi's not done here folks, the referee can't really comprehend this higher-calculus either and quickly breaks up the hold. Pi immediately starts spinning out sine waves, proving its utility to electrical and recording engineers worldwide, but e is unimpressed. Despite lying "undiscovered" for centuries longer than pi, e demonstrates its presence throughout nature in the shell of the nautilus, the expansion of the universe, and even the architectual designs of pi's Greek contemporaries."

"Pi stumbles back, dumbfounded and weakly shields itself with a large circle, but its bag of tricks appears to be running empty, and e is just getting started, as it begins to feed itself into continuously-compounding interest equations, showing off its economic maximizing potential. But it's still not done, it's now rubbing pi's face in the base-e numerical system, with the undisputed most efficient economy of numerical width times radix, leaving no doubt as to where the "natural logarithm" got its name."

"Now I must say here, folks that stylisticaly speaking, pi looks good, but e has the undeniable presence advantage, being found on every keyboard, while pi is inherently difficult to type, not even being included in the ASCII character set. Nobody's confusing e with dessert, either, and the game may be stacked here, but ln(e1)=1, while ln(pi1) is incredibly ugly."

"Pi is definitely outclassed here. It's a textbook case of a long-time champion growing overconfident in its size and inertia and getting out maneuvered by a leaner, meaner number who just wanted it more. The winner by undisputed decision and a KNOCKOUT is...."

"eeeeeeeeeeeeeeeeeeeeeeeeee"

This deathmatch brought to you by by the balanced ternary number 111, and the letter theta


(source here)

Hope this doesn't spoil this for ya, but e wins twice in one day! That's my constant!

e!e!e!e!e!e!e!e!e!e!e!e!e!e!e!e!e!e!

in other news: physics final: one question about entropy of the universe, easy. to be done on Monday with some other physics students. algebra final: done with page one, gonna do a little here, a little there, meeting with someone before wednesday (when it's due.) evil deathly proofs class: must prove at least one more thing for wednesday.

This is kind of cool: why anxiety means homework goes unfinished

My kick-ass rad fem therapist today and I were talking about (what else) the overwhelming anxiety I am having from my proofs class which is coupled with the fact that I went to see him today to ask for help and he just stared at me. (You should listen to him when people who are doing well in the class go in for help, he's super-helpful. All other C students like me say the same thing: when you ask him something he stares at you, but he'll help the people who all ready get it. Being one of 3 resources for the class (another one being his crappy definitions and the third being me, who can't figure out the definitions and is therefore struggling to stay afloat) this SUCKS.)

ANyway, back to my story. There is, of course, some PTSD triggers thrown in there as well. So much about this mirrors being in a house with my abusive mom: having to be somewhere I hate while being helpless and having no one to turn to (b/c yes I *can* get a tutor, but all the math fellows either a) tell me they did horribly at the class, b) took it from someone else and every prof covers different material, or c) blocked it out of their memory), and then there's the constant replays of my mom's voice telling me I'm stupid and a litany of other similar things. HOORAY! Isn't my head a fun place to be these days? My best friend begged me to leave the class (we have similar mental health (dis)Abilities and are always watching out for one another, but I can't. I have 2 friggin' quarters to go and I will have that BS in my hands. Can't change now, don't want to either. Like math, want to continue doing math for a very very long time. Must push through even though b/c of this class they've upped my Xanax AND my Lamictal. Heh. (and I had to double my xanax dose yesterday b/c one just didn't work)

SO, here's the cool part. My therapist likes to explain how these things work inside your brain by modeling it for me. I really like this. SO today she showed me how anxiety and PTSD affect the entire brain, not just how PTSD traps you in your midbrain (and how the techniques we use like EMDR try to put these things into words instead of just emotions which move them out of your midbrain and make them something that is easier to deal with and not an automatic reaction.)

She held out her hand in a closed fist: this is your brain (I know you probably all pictured the frying pan, but shake it out), she then opened her fist and pointed to the middle of her hand and said "this is your amygdala" and then to her thumb and said "this is your hypothalamus" and re-closed her hand. She then said "this is normally how your brain is, but when you get activated, or in a manic state, or in a mixed state (which happens to me when I get activates), or have anxiety this happens" and she opened her hand (which makes sense since in PTSD the midbrain takes over) "and your neocortex is unable to function properly."

I all ready knew that anxiety meant that I was not going to get anything done, but it's nice to have an idea of *why* nothing gets done. Although I'm sure if I had a more technical explanation I would just be confused.

Finals start the 17th, we don't have a final in this class, just a 2 hour class period of, yay, proofs that Wednesday. Everyone keep their fingers crossed that I don't have a nuclear meltdown before then, because it really feels like I am heading for a major one and I really REALLY hate the idea of having one because of something that I put myself through.

*sigh*

I had an anxiety attack talking to my prof trying to do proofs. (He is only helpful to those who are doing well in the class, this has been confirmed by many classmates, the asshole.) SO I left. This period of the class I have only done 2 proofs, I hope that's enough for a C, I did one hard proof so I hope that counts for something. That and I've done a couple of unsuccessful proofs so it's obvious that I'm trying. The 1 mg of Xanax made it kind of hard to finish the proof I was working on since it makes my brain all floaty. *sigh*

Tonight's trivia night and one of two nights a week I get to spend with my math geek and I can't seem to get off the couch. UGH. I don't know what to do. *sigh* Having an anxiety disorder and an anxiety inducing class sucks. A LOT.

Anxiety attack in math class today

I almost started screaming at someone in class today (do you *really* need to prove 3 things in one class when you were the one who proved the most proofs for the "first 3rd". You only raise the bar for the rest of us who were ecstatic (and I'm not the only one) of proving 3 in the last period, now we'll have to do more. We're 2 weeks in and I have none, but then again every time I try to do a proof I have an anxiety attack.) But (thankfully) instead I had a *quiet* anxiety attack and cried for the last 30 minutes of my class. It was AWESOME.

So here's the email I just shot off to my advocate at disability resources:

I have a math class in which my anxiety has got progressively worse in as
the quarter goes on. It's Math 312, Intro to Proofs via Elementary
Analysis. The style of the class is "teach yourself." We are given
definitions and sometimes theorems that, frankly, I do not find
illuminating or helpful and I do not find the prof helpful either. We're
not allowed to use any other resources, other people, books, etc.

Prior to today I was only having anxiety attacks every time I attempted to
do a proof, but today I had an anxiety attack during class. I am having a
horrible time and this class has just made my depression and my anxiety
worse. I can't get myself to school sometimes because of this class. And
I know it's going to get worse. I don't think I will be able to make it
through this class, but it's a requirement.

Is there anything you can do? I have to pass this class, but I don't
think I'll survive this and with only 2 quarters left, and full with the
rest of my requirements I don't think I'll be able to fit it anywhere else
(and everyone teaches the class this way).


Need I say again that I think this class is incredibly unfair to people with anxiety disorders (like me).

Oh and for good news, 48/50 on my Abstract Algebra homework (both points lost were ridiculous, they were things I knew that I forgot to put into my proof. ARGH!) Pure mathematics ROCKS!

i will, i will, i will

I WILL leave the house in time to go to school tomorrow.

I WILL go to EVERY class, even if one of my prof's doesn't lecture on the material (our test on Wednesday had questions from 3 chapters ahead of what we were assigned to study. WHo does that? No reading, no lecture, no homework. I have no idea how the hell we were supposed to know that. I just looked up temperature in the index and read EVERY section on it until I got to the relevant one.) , the other prof lectures straight from the book, and the last class is the evil proofs class where I desperately feel as though I will fly into a blind rage or cry at any given moment.

I WILL finish that damn proof I've been working on for 3 hours. (mixing delta/epsilon proofs with cluster points and continuity (but at least it's a closed set and I *know* how to do it in a hand wave-y way, but not a "rigorous" way *sigh* I can explain the concepts and how it will work, but how to put it all together to form that whole crappy rigorous proof thing, bah. Have I mentioned lately that I hate this class? He doesn't like it when I turn in proofs written in the style that my 401 prof likes them to be written. ARGH. At least I get A's for those assignments, so it's not that I can't write proofs, just not these (since I can't use a damn book)))

I WILL get up 2 hours early to go to my prof's office hours so I can finish said proof.

I WILL do my physics homework tonight, even though I will have an hour between office hours and class tomorrow.

I WILL drink that glass of wine tonight so that I can make sure I will actually sleep so I can get #' 1, 2, and 3 done.

I WILL FINALLY call the doctor's office and make that appointment to up the dose on my medication that I so direly need since I've had a "low mood" (nice euphemism for depression) for the past 3 weeks.

Ugh. *fingers crossed* these things actually happen.

Fighting mental breakdown

OK, so I have 2 math classes. One is a 400-level abstract algebra class that I am doing well in. The second is a 300-level proofs class where I am given a page of shoddy definitions and remarks, am not allowed to talk to anyone, even people in the class, or look at any other books on the subject. Most our grade is from presentation of correct proofs in class, I, of course, am not very confident in my proofs since I am so confused by his notes and talking to the prof is NO HELP whatsoever. It's not like I can't do proofs, 401 is all proofs and I am doing very well in that class. Everyone else has presented 3-4 proofs, and I presented a whooping 1.

I missed class on Tuesday because of a migraine, and I have gone to class with a migraine before, but the way I deal with the inordinate amount of stress is by avoiding the class. I missed class today b/c I missed my first class (she lectures straight from the book, though) and I just couldn't move to get to the proofs class. That's how I deal with anxiety (thanks PTSD), by freezing, or in this case avoiding. I know it's not helping, especially since on Fridays I have to turn in correct forms of all the proofs presented in class (25% of my grade).

ARGH! I need a better way to deal with stress, I know this, hence all the therapy and meds and accupuncture. I would drop this class (never have so many tears been shed over a class) except it's a requirement.

How can I do proofs for my 401 class but not for this one? (Although I have a sneaking suspicion it's because I am able to talk to people and get a better grasp on the material. Group theory, check. Whatever the hell we're doing in 312, definitely not a fucking check.) ACK!

The Moore method sucks. And you know what I remember from my last class that was Moore method? Nothing, except the extreme desire to throw the prof out the window.
