The Imponderable Mysteries of College Life
Pinky, are you pondering what I'm pondering?
Err - I think so, Brain. But where are we gonna find rubber pants in our size?
Quiet, Pinky. Or I shall have to hurt you.


- Pinky & the Brain, "The Animaniacs"

While physicists around the world labor diligently toward the Holy Grail of Physics - the Grand Unified Theory (affectionately dubbed GUT), which ambitiously seeks to unify the four fundamental forces of the universe into a single equation, the average college student is beset by inexplicable forces far more bewildering than anything a physicist can hope to fathom.

The Post-Finals Genius Effect is the unsettling way every concept, every theorem, every formula forgotten during the final comes rushing up the moment the test is finished, a few seconds after you walk out the door.
And even though physicists are allotted obscene amounts of government money to research worthless subjects like String Theory, little remains in the public coffers to fund answers to questions that plague the average college student ... questions like: "How does my roommate get away with sleeping all day and still earn 4.0 every quarter?" "What happens if I use a condom past its expiration date?" "If a married person earns a bachelor's degree, is that grounds for divorce?"

In any event, while one cannot ever hope to adequately fund all the vexing mysteries we encounter, surely a case could be made for research grants to answers to some of the most common and mysterious forces of college life:


The Starving Student Syndrome

Organizers of campus clubs and organizations are intimately aware of the formidable task of recruiting and retaining new members in an campus of otherwise lethargic students. As any of these officers can tell you, the surest way to guarantee new faces at a meeting is to post signs around campus advertising "Free Food." But for all the evil one may say about on-campus dorm food, it remains unclear why if free food is served at, say, 5:00 - the food will inexplicably disappear by 5:05, and the new faces, by 5:15 ... like a swarm of locusts sweeping away edibles en masse. Any public event that caters free food to attract college students suffers from this yet-explained phenomenon. Either dormitory fare has become dramatically worse since I've moved off-campus, or there are heretofore unmeasured quantum-mechanical effects that create localized matter-annihilating wormholes around groups of hungry college students.


The Mathematics Textbook Understatement Paradox

By all appearances, textbook writers, particularly writers of natural science and engineering textbooks, subscribe to strict Science-Textbook-Writer bylaws, which state that everything must be headed with elaborate, scary-sounding titles. Chemistry is particularly good in this regard, with intimidating titles like "Nonlinear Decay of Beta Particles in Radioactive Lanthanide Series Elements" and other text names that make one feel mighty smart to be seen carrying such books about. (Of course, taking a midterm or two in such a course can quickly eradicate such euphoria, but that is the topic of another discussion). One of the primary objectives of intimidating titles of science books is to screen out the unfit by frightening off the lightweights and poseurs.

Yet, while engineering and natural science writers adhere faithfully to the rule of creating intimidating textbook titles, math authors appear to be paradoxically obsessed with understatement. The average engineering student, used to tackling topics like "Nonlinear Beta Decays" and "Closed-Systems Thermodynamics," is wholly unprepared to decipher deceptively understated books like "Elementary Analysis." Elementary Analysis? Hey, they said it was 'elementary' ... how hard could it be? (Answer: "Kick-your-ass with a C+ hard"). Worse: "Partial Differential Equations." Well gee, who hasn't taken a partial derivative before?

My doctor says I should avoid discussions on "Real Analysis," to reduce the frequency of my episodic post-traumatic flashbacks of college so let's just say 'it sucks' and move along, ok?


(continued from main journal)

When even topics bearing the innocuous title "Linear Algebra" are exercises in mind-bending discomprehension, one thing remains clear: if you ever see a required book for a class that even understatement-loving mathematicians would admit is "Complex Analysis," there is only one sensible thing to do - drop the book right there and RUN LIKE HELL.


The Post-Finals Genius Effect

I don't know about anyone else, but 30 seconds after any final exam, my IQ soars to about six trillion, without fail. The Post-Finals Genius Effect is the unsettling way every concept, every theorem, every formula forgotten during the final comes rushing up the moment the test is finished, a few seconds after you walk out the door. Countless imponderables in study sessions, forgotten formulae, fruitless attempts to recall specific theories while staring at your final during the exam are suddenly elucidated within that gut-turning 30 seconds after you turn in your answer sheets. You become a source of SEARING INSIGHTS into the class's material and, for just a brief moment, understand the subject matter with the sort of painful clarity only those of us who've experienced the Post-Finals Genius Effect can truely appreciate.

This all suggests that if there were such a thing as a graded Post-Finals Final, those of us afflicted with the Post-Finals Genius Effect can capitalize on our temporarily boosted IQ and earn a 4.0 GPA on 50-plus units each quarter.


The Textbook Pricing Anomaly - Explained

If you're like me (and may God help you if you are), your high school extracurricular-reading procurement experience was largely restricted to shoplifting Playboys and you've never spent more than $30 in a bookstore before coming to college. Consequently, buying college textbooks the first time (and subsequent times, come to think about it…) is an exercise in jaw-dropping sticker-shock.

Eventually, one also wonders how textbooks are priced-whether there exists a coherent formula to the seemingly inexplicably random numbers that appear on text prices. After exhaustive empirical research (i.e. sitting in my room and making numbers up, just like I do for ECE labs), it is my conclusion that texts are priced as follows:

Price = constant K, times the upper division number of class, divided by the number of pages. Thus, the price of texts are directly related to the upper division number of the class, to reflect your increasing commitment to your major.

Explaination: The closer you are to graduation (reflected in the higher upper division numbered classes you take) the more inflexible your book needs are, giving the administration greater leverage to hose hapless students. This is what economists call a 'price inelastic market.' They would also refer to latter-sequence books as 'complimentary goods' to earlier, introductory text, and then mumble something about illiquid markets that allow book publishers to 'extract rents' from students. The rest of us will simply recognize this as an extension of the screwing we've been getting since the day we signed our first tuition check.

Also: As students progress in college, we become increasingly cognizant of the fact that most PhDs in your field are clueless, thumb-sucking jagoffs who couldn't hold a productive job in the real world, and assigning beastly tomes to freshmen is effective in impressing college neophyte. But as students become wise to gimmicks designed to trick them into thinking professors have anything of substance to say, the intimidation value of thick texts drop dramatically. Thus, with rapidly diminishing incentive to pad upper-division books, text pricing is inversely related to the physical number of pages your book possesses.

Look at your book-buying experience to verify for yourself - the closer you are to graduation, the more expensive your books become … while simultaneously becoming emptier and emptier of content. Astute readers will note that extropolating this theorem to its logical limit suggests that at some point in graduate school, hapless students will forced to fork over an infinite amount of money for a of fortune cookie's worth of text - perhaps something like:

[You will fail your orals and end up a bitter, underpaid contract instructor at a local community college]

In any event, it is clear that massive university grants are needed to continue my research into the remaining unexplained collegiate phenomenon. For if one of the greatest mysteries of college life - the Textbook Pricing Anomaly, can be explained by an online hack with too much spare time, imagine all the good that a federal grant can accomplish with smarter and more capable researchers.

Then again, mayhap you shouldn't.

Well, the mysterious vanishing food is easy to explain. Many college kids are away from home for the very first time, and have to manage their own money for the first time. It takes a while to learn priorities. It doesn't matter if they have a lot or only a little money, because after candy, books, beer, and smokes, there's little left in the grocery budget. This means having to skimp on "real food" quite a bit.



Oh god did I just classify books as junk food?

And definitely beware the textbook titled simply "Algebra". :)

BTW - note that GUTs are way out of fashion - that was like 20 years ago man - they only try to unify the Strong Nuclear force with the unified Electroweak force - nothing's experimentally verified yet (we're waiting for proton decay), but there are plenty of consistent theories.

String Theory (and it's nebulous mother - the mysteriously named "M-theory") is the currently fashionable post-GUT: it is meant to be a TOE : Theory Of Everything (it includes gravity). (Yes, they actually use that term, sometimes...) (and no, not much money actually goes into string theory - it's all theory - experiments are still working on GUTs and Higgs particles and so forth...

yeah, actually, currently fashionable GUTs (the so-called "supersymmetric" ones) predict even longer decay times: 1016 years or so. The way to see this is put 1016 protons in the same box and put a whole lot of detectors around the box and wait for probability to have one of them decaying in a year. The Kamiokande experiement in Japan is looking for this by putting really big tanks of water (like multiple million gallons) deep under a mountain (to screen out cosmic ray noise which penetrates pretty deep underground). They haven't seen a statistically signifigant signal yet though (to my knowledge).

the other dimensions wouldn't be called anything differnt than our current 3 spatial ones are - does "up/down, right/left, forward/backward" have any more signifigance than "plus Z/minus Z, plus X/minus X, plus Y/minus Y"? The other dimensions will just be more spatial ones with no arbitrary names...

except there are current theories (F-theory and it's variants) which allow for *12* dimensions, in which the last extra dimension is not spacelike, but timelike - a universe with *2 times*!!! How do you imagine that? I have no idea, and neither do the people who work with it, as far as I know. It's a bitch to get sensible answers from a theory with 2 times. So most people don't do that, and stick to the 11 dimensions of M theory (or pretend the 11th is ignorable and work in the 10 of string theory).

A extension of the 'Textbook Pricing Anomaly' is the 'buy back anomaly'. The cash the uni bookshop will give you for any returned book won't even cover the price of a beer. This means you can't even drown your sorrows, after realising you've been given the big hard one by the shop.

An alternative method of dealing with used textbooks is the 'I still might need them...' approach. In the unlikely event that you'll ever need to work out the dot product of some vectors (which btw isn't a classy party trick), the answers will be easily available. This is never going to happen though, so the text books become very large paperweights.

Who needs to know about marginal utility anyway?

The Lord God Father Almighty, Creator of Heaven and Earth, of All Which is Seen and Unseen, demands, young Jammer, that you use some of those glorious braincells which I, the Holy Host of Hosts, was so gracious as to bless you with; however, as to spare Myself the agony of disappointment, I shall answer your query for you, lest you flood Me again with a myriad of excuses (in what you try to pass off as prayer -- the horror the horror) for why you haven't heretofor decisively answered your own question.

Acts of God (Me) are not insurable by definition. Your (mankind's) pathetic, insipid, short-sighted definitions ("Act of God") have no relationship to God's reality. A true Act of Mine is something slightly more cataclysmic than say a volcanic eruption, the flooding of an entire continent, or a nuclear reactor meltdown. For men to assign to Me, in My Infinite Glory, such petty so-called "disasters" is irreverent and perfidious in the extreme. When The Lord Your God acts, you may expect an ice age, a planetary collision, a black hole, the explosion of your sun, or Formosan Termites to invade your property in the French Quarter (this is My favorite as of late).

And, Jammy pants, please stop flexing in front of the mirror in the mornings -- it's disrupting when the entire Communion of Saints starts snickering.

The question was whether the attempt to insure against "Acts of God" is blasphemous on the part of the believer, not whether it is, in fact, possible. In a universe with an all-powerful diety, of course insurance is a futile gesture - but that's not what I asked. Then again, changing the topic to toot your own horn has been a favorite smokescreen of yours since Old Testament days, neh?

I've always wondered why an emotionally-secure diety would feel the chronic need to remind everybody his omniscience/power/blah-blah in every other sentence he utters. I've known many humans with the same needy appetite for recognition and try to work into every conversation how beautiful/smart/rich/whatever they are. Invariably, they are all a rather pathetic and unhappy lot. If one of us is a preening jackass, flexing in front of a mirror - it would most certainly be You, not me. Amen.

Look, God - I've never been a big fan of yours. You filled your "Holy Book" with contradictions, allowed millions of humans to murder and terrorize each other in Your Name, and worst of all, flooded the FM airwaves with that godawful Sandi Patty.

Maybe this is all part of some "Divine Plan" - but frankly, I don't see it. Enlighten me.

Chemistry is particularly good in this regard, with intimidating titles like "Nonlinear Decay of Beta Particles in Radioactive Lanthanide Series Elements" and other text names that make one feel mighty smart to be seen carrying such books about.

*lol* Wanna know the name of the English paper that let me graduate high school? "The Roles of Traditions and Christian Moralism as the Eunuchs of Social Institutions in the Destruction of the Individuals Self-Awareness". ('was a critique of Henrick Ibsen's A Doll's House and Ghosts.)

Price = constant K, times the upper division number of class, divided by the number of pages. Thus, the price of texts are directly related to the upper division number of the class, to reflect your increasing commitment to your major.

My future looks rather bleak, then. Since I intend to double-major. ^_~ But we have our means of getting by—last semester there was this sorry-ass "course reader" required for all business students (about business ethics, of all things), and two friends & I (being the good business students that we were) just copied the book for like 20 people and got the price down to $25. (Yes, Cam is a regular criminal.)

Countless imponderables in study sessions, forgotten formulae, fruitless attempts to recall specific theories while staring at your final during the exam are suddenly elucidated within that gut-turning 30 seconds after you turn in your answer sheets.

This applies to hard sciences moreso than others. Try let me balance a simple chemical equation now and all you will get is O_o (and this is from someone who got a perfect score on the AP Chem exam). =P

Renting Textbooks?

2003-10-13 04:01 pm UTC (link)
In my major... you got to know the class before and the class after yours. So, simply put, you rent out textbooks for a semester. A new book would cost around 100-150. You could sell it back used for 20 (maybe 30). They'd sell used ones for 70-90.

Rent the book for 30 with a $40 deposit. Do this 2-5 times and help off-set costs... In any event, you'd always get at more than the buy-back price if nothing else.

2001-07-18 08:35 pm UTC (link)
but if you are nice and simply ask people(professors/TA's/grads) in arcane fields to explain stuff to you in simple english, many of them can. Many professors I have met, when asked to explain things more clearly, or give a relevant example, are more than happy to oblige. Just whatever you do, don't ask your fellow students for help (unless they are proven experts). Years of stuyvesant highschool has taught me that few, if any high scoring students can actually explain what the hell they did to get the score (aside from the cheaters).

Multivariate calc was simply about measuring things in 3-4 dimensions (in laymans terms, let me see what the hell this weird shape does when I spin it for a few seconds). Mathematics is all about simplifying things (in real life) through the use of non-simple means. Hence the disarming textbook names.
advanced chemistry: According to these guys who wrote this thing and experimented a lot, it has been proven that this does that when mixed with some blue stuff (never, ever give in to the urge to sniff it). (people in this field dont remember what it means to read normal stuff, hence weird book names)
Economics: If you find a picture book of it, it isn't so bad. The pictures really make it understandable to most anyone. Its juts a bunch of formulas that make curves move, at least for a good portion of the beginning.

as for cram sessions, if you burn something into your mind, you will feel funny. Same thing as watching a b-movie marathon for too long. the final simply lets you express that stuff you burned in, and thus you have the big picture in mind. textbooks, umm,....yeah, that is what staples/kinko's/copy-places are for =P

Ok, well, let's see......

1) You don't have the GUT equation because I just solved it last night, and FedEx is slow. Be patient, it's coming.

2) I recently ate at a friend's college, and while it was not fine cuisine, the food was palatable, cheap, and plentiful, as in all you can eat.

3) I have yet to buy a textbook for college, and I am able to maintain a 3.3 gpa, so there ;)

4) I have encountered first-hand the "Post Finals Genius Effect". That might be the answer to some of these TOEs and GUTs. Maybe if we gave the geniuses a set amount of time to figure it out and then took their labs away, they would come up with the answer the next day.

5) As for ending up a bitter, underpaid contract instructor at a local community college, that is my plan. One day I will be teaching History 1: The World up to 1648 at the local community college, allowing me to warp a new generation of young Americans and send them to unfulfilling jobs.
