It has been way, way too long since I updated.

I actually took five classes this term, punting 1.00 on the grounds of multiple "meh" reviews. They were:

6.046/18.410 Algorithms. I took it primarily to fill in gaps in the disorganized knowledge I have acquired over the years with random discussions with the likes of ecprice. The most useful thing I took from that class was meeting Prof. Kellis, who does what appears to be highly interesting work in computational biology - interpreting DNA sequences and microarrays to deduce regulatory patterns, systematize gene anotation, and build evolutionary trees. I will have a UROP with him beginning next IAP. (So 6.370 looks unlikely.)

7.05 Biochemistry. I took this to continue exploring my nascent interest in biology and chemistry. The transformation of biology from voodoo to well-motivated series of chemical interactions was pleasant. Excellent coverage of proteins and catalysis, nucleic acids, and sugar metabolism, both conceptually and in practice.

8.044 Statistical Mechanics. This was somewhat random, though a natural choice for a prospective physics major. It was also surprisingly excellent. There was commendably thorough buildup from the empirically motivated axioms of thermodynamics together with a phase-space uniformity hypothesis in the microcanonical ensemble to macroscopic behavior, both qualitatively and quantitatively. The class dispelled misconceptions that quantum mechanics only applies to tiny systems (it applies to stellar physics) and that relativity only applies to huge systems (it matters for calculations involving many heavy elements). It also gave a badly-needed and deliciously rigorous definition of entropy, and contributed to my understanding of chemical equilibria and thus biology. Moreover, the mathematics contained some interesting tricks as well as penumbras of high culture, such as zeta(3) arising in blackbody radiation.

18.330 Numerical Analysis. I chose this to begin shoring up my applied mathematics, particularly for my summer internship in Merck's Applied Computer Science and Mathematics division. A. Toomre is a true goofball who clearly enjoys contest-type mathematics. The class was relatively nonrigorous for a math class, but included enough detail and coding to convince me that the claims were indeed reasonable. Gaussian quadrature, enabling fifth degree polynomials to be integrated from -1 to 1 with but two values was a highlight, together with Adam's methods for solving differential equations. And I shall never forget the ridiculous power of extrapolation.

21W.747 Rhetoric. Well, a HASS-D, but it sounded interesting. I've always enjoyed thinking carefully about the specific effects of wording, and this class did just that. Ethos, pathos, logos, or so the classical style goes. My only objection to this class was a major shortage of feedback and timeliness on the part of the prof.

I had exams in the first three. I felt that 6.046 went poorly, but that grade returned otherwise; the exams in 7.05 and 8.044 felt very good, but neither grade has yet returned.

The 2007 Harvard-MIT Math Tournament, of which I was the Problem Czar, went well. Apparently, I was the only one who thought it was disorganized, reflecting my biased perspective from the most chaotic rooms. The problems were well received, which was a relief. I wrote about 70 of them, struggling to maintain creativity by the end, and did about 90% of the proofing (shoutouts are due to Thobel especially, and TAbbott.) That job was indeed rather hosing by February, and I will return to merely being a prolific problem writer for next year's contest. The only downers were that I didn't really get to chill with people very much, and I no longer recognize the large numbers of contestants I once did.

Apparently I did well on Putnam 2006. I never bothered to find out my exact score, but it must have been at least as large as the maximum of 70 (seven problems solved, commentary on some others) I had predicted for myself, given that I cracked into the money winners this year. MIT again destroyed everyone else, with 5 out of the top 7 scores, 13 out of the top 26, and a third of the HMs and up. In fact, this is the second year in a row where a Random Hall team would have won...

As far as other miscellaneous activities, the term included the USAMO grading and the COMAP MCM. There is a fairly good chance that I'll get to fly out to MOP 2007 to give some lectures, though I won't be there the whole time due to my summer internship in Rahway, N.J. I am thinking one will focus on motivation and how to think productively. I am not sure what else I'd like to do, perhaps Inequalities redux...

Bonfire is now addicted to "Doctor Who," "Heroes," "House M.D.," "The Daily Show," and "The Colbert Report." Sadly, SG-1 is essentially over and Battlestar Galactica is taking an overly long season break and won't return until 2008. I forget when Atlantis resumes... and the House season finale is this Tuesday.

I can't think of anything else to say.

SOTU: In a word, lassitude.

I finally started reading, thanks to some external poking. C. S. Lewis writes rather witty prose... or my brain puts together humour where it isn't intended... Or both.

Tarukaja! I did a 1 rep max on bench press at the Z the other day. Had to stop because the place closed at 11. I was still going strong (ha ha) and had nearly conquered the full stack. Rakukaja! My cardio state is in fact not broken; actually, quite the contrary. I'm just easily made anxious.

Moo! 34ish TP problems down, N to go. I'm definitely learning the thinking that goes on behind implementing algorithms.  "This is very fast, but it's a pain. This is trivial but slow, but actually fast enough." Modular thinking.++ Coding_habits.improve(). Who knew classes could make a difference? Maybe in a few months I'll consider myself competent as far as the programing side of CS is concerned.

"Timelords - Doctorin' the TARDIS." I finally understand this song! I've been hearing it on the family trips to Alabama since I was a little kid (it was on a tape given to my folks by an uncle together with other unusual music.) Turns out it's the full version of the theme song to "Dr. Who," the venerable British Sci-fi. Catchy.

BSG returned, after another mid-season. The writers did not include the usual insane cliffhanger at the end of the episode, but they did play the "lol, there are five more" card quite extensively. The lounge offered wide speculation as to who the remaining models could be.

No kidding, I am about as relaxed as I have been in the past five years. Not quite Peter Gibbons, but close. It's just great.

The first rule of war, know thyself:


Abortion - I am generally opposed to it, particularly to later term abortions, but I have no qualms with contraceptives, or the morning after pill. Even given the direct biological progression, I find it difficult to equate a newly conceived unicellular zygotic being with a human being.

Affirmative action - Although I support the notion that diversity is desirable, I am furiously opposed to the ways affirmative action is usually applied. Not only was the University of Michigan's admission policy blatant racial discrimination, it was an undue slap in the face of the "bonus" recipients. All races are perfectly capable of great achievement. I do not buy any of the arguments to the contrary.

Dead white males - I don't feel particularly strongly either way on this issue. Most of the history directly responsible for shaping my life thus far was indeed dominated by peoples of Anglo-European roots. How much focus should be placed on the specific leaders? It's not clear.

Race and intelligence - As you could probably guess from the above, I am skeptical about such a connection. Maybe IQ tests purport to indicate some racial discrepancy, but there are lots of other explanations. What is intelligence? Do IQ tests measure it? Have the test takers had the same environmental influences?

Creation-evolution controversy including Intelligent Design - I don't believe in a literal read of Genesis I, but if you accept that the Bible invokes metaphor, then it's quite a plausible story. What was the formation of the earth but a chance amalgamation of space dust? Who's to say that there isn't a God behind the scenes manipulating probability? And the same goes for evolution. It's analogous to stacking a deck of cards.

Censorship, videogame controversy - I am generally opposed to censorship and believe that consumers should be responsible for regulating themselves. One person's preferences should not dictate another's. I don't think there's a causal effect between videogames and the people playing them. I've played plenty of first-person-shooters, and yet I feel no desire whatsoever to own or discharge a firearm. On another scale, the media that purport to be factual had damned well better be factual. Dan Rather's memo and Newsweek's flushed Koran are two of the more egregious examples I can recall. I prefer self-regulation in this regard, but if that repeatedly proves insufficient, then censorship is ok by me.

Capital punishment - I used to be quite tolerant of this practice, but more recently it has come to my attention that plenty of convictions leading to this punishment are based on faulty evidence. I now view it as dubious practice to execute without clear forensic evidence. In particular, witness testimony should not be the sole basis for capital punishment.

English-only movement - The taxpaying citizens of this country should all be allowed to vote with ballots that they can understand. However, choosing from a comprehensible list of names on a ballot in a foreign language does not of itself constitute understanding or an informed decision in my opinion. If enough serious material is available in a second language, then it is fine as an alternate language for a ballot. But the national language is English (perhaps not legally, but it should be), and providing translations to a language appearing only on a ballot is lip service.

Environmentalism and global warming - This is a serious issue that is too often neglected in politics, particularly by the right. The Washington Post editorial  http://www.washingtonpost.com/wp-dyn/content/article/2006/07/10/AR2006071001145.html?referrer=email  gives a good explanation of the global warming situation. We are the world's premier species, which empowers us to do quite a bit to the planet, but wreck it is not one of those things. It's too bad nuclear power was derailed in the U.S. for decades and is only now re-emerging in political rhetoric. We are years behind countries such as France, who run their electrical grid primarily with this clean power source.

Family values - It's a shame the Equal Rights Ammendment did not get ratified. Sex discrimination goes hand in hand with racial discrimination as something that is too often condoned in practice, even in a casual setting. That I have many smart female friends; they should not have to tolerate chauvinist rhetoric. As for homosexuality, I trend toward the don't ask, don't tell policy. If I could, I would make everyone in the world heterosexual and be done with it, but things aren't so simple. I think a quasi-equivalent civil union, but not marriage, should be available to them. I think there's too much energy spent lobbing animosity at gays; why should they be barred from visiting each other at deathbeds?

Media bias in the U.S. - The media tends to focus on material that makes entertaining news. Most often, this is negative content. This is how a dozen bad apples at Abu Ghraib and Guantanamo can be the focus of the news for years. A fact, never disputed by any political figure who isn't being a demagogue, is that the overwhelming majority of the hundred thousand soldiers deployed in Iraq have done nothing but fight terrorists. It's shameful that the media insist on tarring them by focusing on the relatively few negative aspects of war. The media loves digging up dirt and opposing whatever administration is in charge. Thus, I am not surprised or concerned by the fact that I find more leftist commentary in my reading.

Moral absolutism vs. moral relativism - I believe that there exist some standards that transcend cultures. A society's particular belief system may empower it to do terrible things: the Holocaust, slavery, etc.) However, appropriate scope cannot be ignored, and strikes me as the more relevant factor. It's bad to point a real gun at someone. It's worse if that gun is loaded. If I shoot and kill someone, that of itself is wrong. If it turns out I shot this person in defense of myself and my family and had no other options, then it is less wrong. If this person was also about to slaughter all other living beings on the planet, it's still less wrong.

USA PATRIOT Act - (It's actually a really long acronym! "Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism") One thing that strikes me as ridiculous is the way people fight so hard for their privacy when the government collects individualized data in the name of combating terrorism, but couldn't care less when similar data is routinely assembled and shipped off to Economists and Sociologists working on their Ph. D's. Does it harm you to suspect that there may be someone in the CIA logging your phone conversations? In my mind, the only legitimate objection is that the government has lost many personal records and, some would argue, surreptitiously exposed millions of Americans to potential identity theft.

Permissive society - I view society's increasing tolerance as a good thing in general, but I hope we're beginning to reach a stopping point. Things were awfully conservative in the early 20th century and before, but now taboos are an endangered species. If you've seen late night comedy, you know that almost nothing is off limits at this point, and the clothing front has nearly disappeared. There needs to be a little mystery...

Political correctness - We shouldn't show total disregard for refined speech, but I think rewriting the English language is a bit extreme. Maybe I'm a traditionalist, but do people really take that much offense at language? "chairman" is now "chair"; "man does not live by bread alone" is now "people do not live on bread alone" (yup, we're editing the Bible!); "imbecile/moron/idiot" became "mentally retarded," which became "slow/mentally handicapped," which became "mentally disabled," and then "mentally challenged," and finally "developmentally disabled." Amusingly, Wikipedia points to what I think reads more like a retrogression - "impotence" has become "erectile dysfunction." For a period in 2005, the Florida State University Seminoles had their name deemed 'hostile or abusive' by the NCAA, over the objections of the actual Seminole Tribe of Florida who supported the school's name! And of course, Christmas and Easter now appear on calendars as Winter and Spring Holiday.

Right to die movement, euthanasia, and Terri Schiavo - I think this should vary on a person to person / family to family basis. Although in general I don't feel strongly either way about these choices, I dislike the government forcing itself into this difficult issue. What happened to Terri Schiavo was flagrant overreaching by the political leadership of this country.

Separation of church and state, public displays of the Ten Commandments, and religious freedom - The constitution specifically prohibits state religions. Thus, readings specific to particular denominations should not be permitted; organized prayer is too structured to be allowed in public schools. However, more general statements are ok, such as the mention of God in the Pledge of Allegiance and public displays of the Ten Commandments (though it may not regard them as divine in nature, is there a mainstream religion that does not endorse the message of the commandments?)

Sexual revolution - Everyone should be educated to the point where they understand themselves and what is going on as far as the matter is concerned. Their decision as to the role of sex in their lives should be theirs alone (provided it doesn't involuntarily subjugate others.) I happen to agree with the abstention that is currently advocated in classrooms, on grounds of both safety and personal convictions.

Stem-cell research - I don't encourage the destruction of life, but embryos which are already slated for destruction can at the very least have a more productive existence in terms of research use. The current federal guidelines are a bit too strict for my preferences. Not enough biology is known for me to advocate restricting our research to adult stem cells.

Transhumanism - The use of technology to better our lives is highly tempting. I without hesitation advocate its use to restore function to people with disabilities, but enhancing the average person through technology is a slippery slope we'd best avoid.

Women in combat - I don't feel particularly strongly either way on this issue. The current selective service program enlists only males aged 20-25, and women are not allowed to serve in active combat roles. It seems perhaps unfairly discriminatory, but I think the arguments in favor of it are slightly stronger than those opposed.

I still haven't written a summary of my first year at MIT. I'll do that at some point...

Tuesday, January 31, 2006

I get to pay taxes this year.  It strikes me as appropriate to write a money oriented entry here.  Allow me to rant a bit, being as I am a fiscal conservative deeply troubled by the cavalier manner in which our national government adjusts its budget. I will try to be educational to make it tolerable.

My source is The Concord Coalition (see website http://www.concordcoalition.org/), one of the precious few bipartisan organizations today, which is "dedicated to informing the public about the need for generationally responsible fiscal policy."

This was today's Reference.com fact of the day (which ultimately led to this entry):

"Ida May Fuller's first monthly retirement check, paid on this day in 1940 from the Social Security program, was for $22.54. Ms. Fuller had worked for three years under the program, which had been established in 1935. The accumulated taxes on her salary over those three years were $24.75. She lived to be 100 years old, collecting $22,888 in Social Security benefits."

To anyone who can do math, it's clear why such entitlement programs are an astonishingly huge drain on the national budget.

Now, that particular example is extreme. Ms. Fuller was the first recipient of social security checks who happened to have only been working a few years under the tax, and she happened to live to be quite old. But the problem is, SS benefits received by a person after retirement can easily exceed money paid in by that person. The two major reasons are:

1. Longer lifespans, meaning longer retirements over which those checks are collected.
2. The rate of return is pegged to a national standard of living.  Over time, that standard, purchasing power (i.e. wages versus inflation), has increased, and will probably continue to increase.  Expected SS checks will grow in tandem, compounding the spending.

Serious adjustments made for the purpose of ensuring future solvency will therefore address causes 1 or 2, or both.  But reading the news lately, I have seen all too well how easy it is for demagogues to rail against benefit cuts.  Tampering with the retirement age for full benefits (i.e. increasing it) will be hugely unpopular with the uneducated majorities of younger generations, while option 2 seems out of the question as it directly reduces the checks being mailed to beneficiaries.  Thus, programming into law such gradual and tremendous automatic increases in entitlement spending strikes me as massively irresponsible at best, while underhanded and insidious at worst.  Even supposing that it was all well intentioned, SS as it stands faces moral questions.  For instance, variance in life expectancy (women usually outlive men, minorities do not on average live as long as whites, etc.) leads to variance in benefits.  Are those benefits fair and equitable to all demographic groups? And so on.

Social Security is at least sustainable as is for a few dozen years.  Medicare and Medicaid , however, face far more immediate crises.  Their difficulties are more complicated, stemming largely from stunning and egregious spikes in the cost of health care.  Given the lobbying power of the pharmaceutical industries, and Congress's general misgivings over private sector regulation, we can expect little help on those fronts in the near future.  This, even though the troubled programs aim to assist particularly vulnerable segments of the population, so acting to repair them is ever the more important.

So, until the blind big spenders in Congress are replaced by straightshooting representatives with foresight (a la McCain), we can expect the rise of national debt and anemic government programs.  Repeatedly raising the statutory debt limit does not constitute a solution to the problem, nor does it signal fiscal responsibility.  It may give the Treasury the legal authority to continue borrowing, but it certainly does not avert what could become a calamitous federal failure.
