A different(ial) integral

Today I am simply posting an entry from the blog which I mistakenly visited instead of this one, the short-lived and now defunct 'Marinating in the Blood of the Proletariat', whose URL is for some reason integral.blogspot.com. It is one of three posts from late fall 2001.

Why am I doing this? You can marinate on that y'self for a while, as OutKast once said. Maybe it is a kind of "Pierre Menard, Author of the Quixote" thing - the reclaiming, reunderstanding, reproducing, of a text, or something. Comments are encouraged.

Here follows the post:

Alrighty, then. Well, here it is Friday already; another week rushing by in the blink of an eye (trite alert). I need to find a way to make time slow down. My life is speeding by me and I'm on the couch eating popcorn. Well, figurative popcorn. Although I do eat popcorn occasionally. And I occasionally sit on the couch. So I am not being entirely dishonest. And by dishonest I mean not telling the truth in its entirety. And by that I mean that I like peas.

I would suggest that maybe I just don't do enough, but I am constantly busy. Maybe too busy? There has to be a line to draw somewhere. I'm just afraid that I'll close my eyes and when I open them again I'll be old and have never gotten to do what I want / need to do this time around. I'm not sure I even know what that is, yet. I'm pretty sure that this whole doctor thing is a good idea. I really care about people and I'm glad that my career will help people live better lives and be happier in general. I just... wanted to be Indiana Jones, that's all. I want some adventure. And I want to kill nazis.

Kevin's stuck at the computer lab again tonight finishing up his Open GL project. I was trying to get ahold of Dave so that I would have something to do other than hang out on somethingawful all night (I spend so much time there). Jeff wanted to do something, but I know that that would be a bad idea, and plus seeing him and talking to him still makes me really uncomfortable. I'm not sure we'll ever be friends again and I can't say I'd mind. Every time we talk he brings up my "needing to leave Kevin." It sucks. Kevin is the best thing that has ever happened to me, and I don't mean that in the cliche sense. Jeff has always been jealous, and it's getting really annoying. He's going to Peru for Christmas break, so I don't have to worry about him for at least a month. I can't wait until next year when he doesn't live right fucking next door to me. Maybe he'll leave the country. Maybe he'll leave the planet.

I need to find some friends who are female.

Weird geometry

The area of a hyperbolic triangle, call it ABC, strangely enough doesn't depend on the lengths of the sides. It is totally determined by the angle measures. So for any two hyperbolic triangles ABC and DEF, if angles A=D, B=E, and C=F, then ABC and DEF are congruent. Weird!

The area of a hyperbolic triangle is given by

Area = π-A-B-C

where A, B, C are the measures of the named angles in radians. (In the special case of a triply-asymptotic or ideal triangle, where all three vertices lie on the boundary "at infinity", the area is simply pi. Weirder still! The area of a TRIANGLE is the ratio of the circumference of a circle to its diameter? (The picture shows two ideal triangles in the Poincare upper half plane model

Perhaps weirdest yet? In spherical geometry, the area of a triangle ABC is r²(A+B+C-π). r² here is the square of the radius of the sphere. Usually one chooses the unit sphere, so the term disappears. But what happens if you use i, the imaginary unit, instead? Well, you get

Area = i²(A+B+C-π)
= -1(A+B+C-π)
= π-A-B-C

which is the formula for the area of a hyperbolic triangle. Consequently, hyperbolic geometry "is just" spherical geometry on a sphere of radius i.


:O

What Was Just Barely not a Confessional Poem

Aristotle, from Nicomachean Ethics:

"The perfect form of friendship is that between the good, and those who resemble each other in virtue. For these friends wish each alike the other's good in respect of their goodness, and they are good in themselves; but it is those who wish the good of their friends for their friends' sake who are friends in the fullest sense, since they love each other for themselves and not accidentally. Hence the friendship of these lasts as long as they continue to be good; and virtue is a permanent quality. And each is good relatively to his friend as well as absolutely, since the good are both good absolutely and profitable to each other. And each is pleasant in both ways also, since good men are pleasant both absolutely and to each other; for everyone is pleased by his own actions, and therefore by actions that resemble his own, and the actions of all good men are the same or similar.--"

Wouldn't it be wonderful! But is there really a type of friendship that looks like this? I believe the key to this passage is exactly the last line: "...everyone is pleased by his own actions, and therefore by actions that resemble his own, and the actions of all good men are the same or similar." This is the point! Agreement, in character and action, is what we are in this for. What are we if we don't agree? What is truth without agreement? What is the improvement of society without agreement? If even our closest friendships, our dearest loves, don't point toward some kind of ultimate, invulnerable oneness of opinion and action - why have them?

A Nietzschean aphorism:

For man, to be alone in his thought is worst of all.

It's a Wonderful Life: parking tickets in Buffalo

On my block in Buffalo, you have to park on one side of the street from Sunday to Wednesday, and the other side the rest of the week. In the handful of months I've lived here, I've gotten more than a couple citations for violating this rule, which, as I hope it goes without saying, does no good for anybody and exists to generate ticket revenue.

Last month, I was parked on the "wrong" side of the street and got two tickets in less than a day. First they left one on my windshield. Then it snowed a bunch. The diligent and scrupulous Buffalo police, not now seeing the snow-covered ticket on the windshield, went ahead and left another in the door crack.

WTF, BPD?? I was mad, but I thought I had right on my side. I photocopied both tickets, paid the first one on time, and plead innocent to the second. Today I had my hearing. I had to get up early and pay for parking by City Hall (not to mention getting lost for about 20 minutes downtown), but I was willing to accept that. This is why the hearing process exists, right? So, if silly oversights happen - like being written a second ticket by somebody who can't see that you've got one already - we can set things aright.

Nope! The woman who did my hearing smugly and coldly informed me that you can, perfectly legally, get a ticket EVERY HOUR for parking violations. "Um, I'm going to have to find you guilty." Um, I'm going to have to find you a soulless, corrupt hack. Too bad you missed your true calling as Stalin's personal secretary.

Part of me wants to protest somehow, but my beliefs in the worthwhileness of civic self-respect, of speaking truth to power, of human dignity and the spirit of fairness prevailing over the mean letter of the law, have been laid low this day.

Oh, the irony!

The Philosophical Gourmet Report, an influential and famous ranking of philosophy graduate programs based on surveys of pro philosophers, is known in some circles for its sometimes unfair or inane deliverances. Here's a good one:

My school, UB, is ranked in the 5th group (meaning rather respectable) of programs for feminist philosophy. I have no other explanation for this than confusion. Our feminist street cred? We have exactly one woman full professor, by specialty an aesthetician, who teaches a token class on de Beauvoir every so often. We have one other woman on the faculty. Neither she nor anyone else at UB works on anything you could mistake for feminism from a mile away.

On the other hand, my girlfriend's school, Michigan State, earned no ranking at all for feminism. This while their former chair (now a Dean, but still quite involved in the department) is a major and original light of feminist academe. Not to mention the big appetite for social philosophy and cross-cultural feminism they have there. No grad student in her right mind would come to UB to become a student of Carolyn Korsmeyer (with all due respect) qua feminist, but MSU, a smallish department, attracts a good handful.

Another reason to roll your eyes at this stuff, dear Integrands...

Asia wins again! (a perfect pitch experiment)

In a crazy study (well, a normal study with crazy results) conducted by some folks at UC San Diego, it was found that music students who grow up speaking toned languages, like Mandarin Chinese, are whoppingly more likely to have perfect pitch than non-toned speakers.

(A toned language is one where the pitch of spoken words partly determines their meaning.)

The foci of the study were groups of young adult music conservatory students in the U.S. and China. The difference in perfect (or "absolute") pitch possession, where both groups had begun musical training between the ages of 4 and 5 was... ready?...

74% for Mandarin speakers vs. 14% for Westerners.

And here we all thought only a few special ingenues could do that. The authors suggest that, contrary to what most of us thought, most anyone can acquire perfect pitch if they are exposed to performatively important tone differences in their early years. Want to raise a Mozart? Try hiring a Chinese nanny.

The paper, by the way, is here.

Learn from the Tao

Tao Te Ching XIII:

Pride and shame cause us much fearful anxiety.

But our inner peace and distress should be our primary concerns.

Why do pride and shame cause us so much fearful anxiety?

Because:

Pride attaches undue importance to the superiority of one's status in the eyes of others;

And shame is fear of humiliation at one's inferior status in the estimation of others.

When one sets his heart on being highly esteemed, and achieves such rating, then he is automatically involved in fear of losing his status.

Then protection of his status appears to be his most important need. And humiliation seems the worst of all evils.

That is the reason why pride and shame cause us so much fearful anxiety.

[The Tao Te Ching gives me solace when I feel "fearful anxiety".]
