Regression via Music

Courtesy of YouTube, I toured some of my earliest musical memories today. Several hours of this nostalgia is truly mind-altering. The experience is available to virtually anyone. Just plug the names of your favorite childhood bands/songs into the search box on YouTube, and let the memories wash over you. If you have a hard time drawing out these names from your failing hard drive, check out Wikipedia's list of pop hits via year.

Music is ubiquitous, but what was the first tune that really evoked something for you? For me, it was George Harrison's "My Sweet Lord". As best I can recall, I was in a YMCA van in the San Fernando Valley, on an excursion to Canoga Park. That must have been around 1970 or 71. The song is hypnotic, spiritual, trans-cultural, and boundary-breaking. If you believe in "imprinting", that one song might explain a bit of my personality.

Shortly thereafter, the family up and moved to the East Coast. My fourth grade teacher would allow students to bring their favorite 45's and play them on occasion. A few years later I'd be able to apply words like "sappy" or "pretentious" or "hollow" or "gutless" to music, but not at that time. The Partridge Family was popular, and I'd be lying if I said that some of those tunes don't still touch me. "I Can Feel Your Heartbeat" was my fave.

There were pop songs by singers/groups like the Turtles, Paper Lace ("The Night Chicago Died"), Three Dog Night ("Black and White"), Grand Funk Railroad, Looking Glass ("Brandy, You're a Fine Girl"), Tony Orlando ("Knock Three Times"), and Loudon Wainwright ("Dead Skunk in the Middle of the Road") floating around the room. I wouldn't expect a 2008 pre-teen to dig that stuff...much of it lacks the dense "wall of sound" that we now expect. Too rinky-dink, too much bubblegum. Ballads, high concepts.

For whatever reason, you didn't hear the Beatles or the Rolling Stones in that room. Perhaps it just boiled down to the particular tastes of the older siblings of my classmates. Maybe it was one dominant classmate who always managed to get his K-Tel hit album pushed to the front of the cue. Don't recall.

One song that holds up really well, though, is the Raspberries' "Go All the Way". Up to today, I had thought the title was "Don't Go Away". Try not to get hung up on the early 70's fashion and mannerisms:



That clip was from the "Mike Douglas Show". There's a longer version of the clip on Youtube where the band meets Billy Jean King, fresh off her whipping of Bobby Riggs, following the performance. Issues of race and gender permeated the culture. Hell, you can even find a YouTube clip of the entirely un-controversial Partridge Family playing "I Think I Love You" under a "Woman Power" banner.

As I write, I've segued into the Partridge Family's "Point Me in the Direction of Albuquerque". For quite a while, my 9 year old brain (and a very naive 9 year old brain at that) interpreted the song as an ode to Thanksgiving..."Point Me in the Direction of Our Turkey". Anyway, I can't say I dislike it. The lyrics are derivative in the sense that every other songwriter was already tinkering with the theme of hopping into a bus or a car or a train, or hitchhiking, with or without a dog, and sucking in the grandeur of the USA. What happened to those tunes? Gas prices, I guess.

********************

Now, fast-forward through progressive rock, disco, punk, new-wave, grunge, etc., to Bangkok in the mid-90's. It's odd how certain tunes find popularity here in Southeast Asia, when it eludes them in their countries of origin. Everyone here knows "Love Me Love My Dog" by Pete Shelley. Dig it up. Lobo is popular ("Me and You and a Dog Named Boo", "I'd Love You to Want Me"). Have you heard Dan Fogelberg's "Sutter's Mill"? A lot of Thais have.

Another song that met some success in Southeast Asia was "Knife" by a dude who went by the name "Rockwell". He'll be remembered as a "one hit wonder" in the States for his "Somebody's Watching Me", with Michael Jackson singing backup. He's also the son of Motown founder Berry Gordy. "Knife" is a tender, heartfelt, tuneful breakup ballad...it deserved some success back home.

With a cassette of these Southeast-Asia-only hits playing endlessly in the background, my (ex) girlfriend Noina and I spent a tearful night together. I had to fly back to the States, and couldn't say when I'd return. The lights were off, all words exhausted, but neither of us could sleep. We just snuggled, all sweaty in a one room apartment with no air-conditioning. Thus these tunes, composed in the 70's and early 80's, were stamped in my brain in the 90's. Hearing them in 2008, memories of those feelings, that time, and that place come flooding back.

A Culturally Biased Number Puzzle

Below is a number series puzzle. I'll give the answer midway through this post.

1
11
21
1211
111221

What's the next number in the series? It's not as easy as it looks.

I'm guessing that Thais would find this puzzle more difficult than would English speakers. Here's the version that would probably be easier for a Thai, and more difficult for a Westerner:

1
11
12
1121
122111

Much ado is made of "cultural bias" in various psychometric tests. I don't have strong opinions on the issue. It seems reasonable to think that steps can be taken to minimize, if not remove, cultural bias. It should also be possible to make post-test adjustments to account for such bias. Sparks start to fly when someone implies that one ethnic group is brighter than another; this accounts for the intense academic interest in the subject.

I'm no linguist, but it seems that many languages in this part of the world make heavy use of "counters". The Thai language has about 200 of these words. Indonesian language has many. I've been told that Chinese does as well. English language has a few commonly used counters as well. If you say, "I'd like two loaves of bread", the word "loaves" is the counter. For many objects, English speakers forego the counter (e.g. "She has three stamps"). The Thais, however, use counters for virtually everything. In Thinglish, you'd say "She have stamp three flat thing". There's a special word that helps you count small flat things. In Thai, at least, the counter always follows the thing you're counting, so you wouldn't hear "She have three flat thing stamp".

So, coming back to the puzzle, if you ask a Westerner, "What do you see below?"...

1

...he would say "I see one one".

11

Ask him again, and he'll say, "I see two ones".

21

Etc.

But, try the same game with a Thai:

1

In Thinglish, he'd say, "I see one one tua". ("tua" is the Thai counter for letters and numbers)

11

Now he'll say, "I see one two tua".

12

Etc.

By now you probably understand the puzzle. The final number you see in the Western version of the puzzle is 111221. The number has three ones, followed by two twos, followed by one one.

312211

The final number in the Thai version is 122111. That number has one one tua, followed by two two tua, followed by one three tua.

112213

Interestingly, if you reverse the Western result, you get the Thai result!

Another question: given a "seed number" of 1 through 9, will any of the strings eventually converge? For example, if you start with 2, will these strings eventually merge with with the strings you get if you start with 3? If you use the Thai counting system, it will be easier to realize that the answer is "no"!

In any case, it seems reasonable to believe that one version of the puzzle would be easier/more difficult for Westerners/Thais, given their linguistic habits. A test maker could easily be ignorant of these differences.

**********

A Westerner might find the Asian use of counters to be inefficient. It certainly is, if you're talking about compressing information into the shortest possible sentence. But there are plenty of inefficiencies in the English language. Why say "This is a table" when you could simply say "This table", as you would in Thinglish? Language is not simply about compressing information. It's about offering up information in ways that other brains, with limitations on speed and capacity, can understand. Different languages deal with these limitations in different ways.

Eating Lethocerus Indicus



A perusal of this blog provides ample evidence that culinary sqeamishness isn't one of my weaknesses. I've gobbled many a six-legged creature here in Thailand, to impress, shock, satisfy a dare, or possibly to fill my stomach. The usual mode of preparation is to fry the critters. The (presumably) gooey innards are lost in the process, so you wind up with a clear plastic bag full of crunchy exoskeletons. The vendor has a spray bottle of soy sauce on his cart.

The giant Thai waterbug is different. The males, at least, don't meet their destinies in hot oil. Instead, their reservoirs of pheromones are removed. The pheromone is then used in various sauces. I've tried these sauces.

It's difficult for me to see the appeal. Nail polish remover, ethyl acetate, is the closest comparison I can make. Others claim that the notes of gorgonzola cheese offer similarities (olfactory perception is sooooo subjective). The prime scent components of gorgonzola, however, do not include hexenyl acetate, the waterbug's love juice. You may not be repulsed at the odor of nail polish remover, but you don't mix it in your hollandaise sauce either. Some Thais might claim that essence of waterbug is a taste that only true gourmands can appreciate. For me, however, the real gastronomical delights on this planet are all united in one characteristic: complexity. But pheromones are, by nature, simple, a single chemical that interacts with a single receptor on your amour's antennae.

Thais call the waterbug "mangda". This is not to be confused with horseshoe crabs, whose eggs truly are a delicacy, which also go by the name "mangda". The Thai word for "pimp" is also "mangda"...it seems that male horseshoe crabs are lazy creatures that often get around by hitching a ride on the backs of females.

I'd post my own photos of the waterbug, but the following, awesome video by an honest-to-goodness zoologist is all you really need.



How many times in history has a Thai waterbug found itself on a $2 bill?

Missionaries in Thailand

โดยปกติแล้วคนไทยที่นับถือศาสนาพุทธนับถือพระเยซูเป็นที่เคารพบูชา ดังนั้น จึงทำให้เขาใช้คำว่า “พระ” ก่อน “พุทธเจ้า” เพราะว่าโดยปกติแล้วคนที่นับถือศาสนาพุทธจะไม่ทำตัวเป็นศัตรูกับศาสนาอื่น ๆ

นั้นนับว่าเป็นสิ่งที่ดี แต่คนไทยควรจะรับรู้ว่า บางศาสนามองพุทธศาสนาว่าเป็น คู่แข่ง โดยส่วนมากแต่ก็ไม่ทั้งหมด คนคริสเตียนเชื่อว่าคนที่นับถือศาสนาพุทธหรือคนที่ไม่นับถือคริสเตียนจะไปสู่นรกเมื่อตายไปแล้ว

แล้วอีกอย่างคือ คนคริสเตียนส่วนใหญ่เชื่อว่านั้นเป็นหน้าที่ที่จะชักชวนคนพุทธให้กลายมาเป็นคริสเตียน บางครั้งอาจจะเป็นเพราะว่าในคัมภีร์ไบเบิลพระเจ้าท่านได้สั่สอนผู้ติดตามของเขาให้เป็น “ผู้ตกคน” ความเชื่อเหล่านี้ได้เผยแพร่ไปทั่วโลกเพื่อที่จะพยายามชักนำคนที่ไม่เชื่อให้กลายเป็นคริสเตียน คุณสามารถพบเห็นบุคคลเหล่านี้ได้ทั่ว ๆ ไป ในกรุงเทพ และที่ ๆ คนจะได้รับการศึกษาและอาหารโดยปราศจากค่าใช้จ่ายเมื่อเปลี่ยนศาสนาเป็นคริสเตียน เช่น ภาคอีสาน บางครั้งคณะผู้สอนศาสนาจะเชื่อเชิญคุณให้ร่วมงานเลี้ยงด้วย (โดยปราศจากแอลกอฮอล์) เพื่อที่จะชักชวนคุณให้กลายมาเป็นคริสเตียน

ผมไม่ได้เขียนบทความนี้ขึ้นมาเพื่อที่จะต่อต้านคนคริสเตียนและศาสนาอื่น ๆ แต่บ่อยครั้งที่คนไทยมักจะหลงเชื่อความจุดประสงค์ของผู้สอนศาสนา คนไทยจึงควรตระหนักถึงอันตรายที่จะเกิดขึ้นต่อศาสนาและวัฒนธรรมไทย จากคนที่คลั่งไล้ศาสนาเหล่านี้

ถ้าคุณไม่ได้อยู่ในประเทศไทย คุณจะรู้ว่าบางคนดูหมิ่นพุทธศาสนามาก แต่ถ้าคุณอยู่ในประเทศไทยจะคุณไม่สามารถรับรู้ เพราะ บางครั้งคุณไม่สามารถซื้อหนังสือ หรือรับข่าวสารที่ดูถูกดูหม่นพุทธศาสนาได้นี้คือเวปไซต์ตัวอย่างที่ที่ดูหมิ่นพระพุทธศาสนาเป็นอย่างมาก ผมจะให้ลิงค์กับคุณเพื่อที่จะพิสูจน์ประเด็นนี้ของผม

*******************

Thai Buddhists usually accept Jesus into their pantheon of holy figures. That’s why they put the word “pra” before “Jesus”. That’s because Buddhists don’t usually see themselves as being in conflict with other religions.

That’s very nice, but Thais need to know that some religions definitely do see Buddhism as a competitor. Many, though not all, Christians, believe that Buddhists and other non-Christians go to hell when they die.

What’s more, many Christians believe that it is their duty to convert Buddhists. Perhaps this is because, in the Bible, Jesus instructs his followers to be “fishers of men”. These believers travel around the world trying to convert non-believers. You can see some of these people in Bangkok, but there are more of them in places like Isan, where people can get free education and food if they change religion. Sometimes, these missionaries will simply invite people to a “party” (no beer!) in order to convert you.

I’m not writing this to bash Christians and other evangelicals. But Thais are often very naïve about the intentions of missionaries. Thais should be aware of the threat to Thai culture from these religious fanatics.If you have lived outside of Thailand, you may know that some people are very insulting to Buddhism. If you live inside Thailand, you probably don’t know this, because you can’t buy books that insult Buddhism. Here’s an example of a website that insults Buddhism and Thai culture. I give you this link to prove my point.

***********************

No, I didn't translate myself!

The sentiment is earnest. Most Thais don't seem to have a clue about the evangelical, viral nature of some belief systems.

In a weird sense, though, the tolerance of most Buddhists toward other religions may actually provide some immunity to these viruses. When evangelicals begin their Jesus spiel, the Thai Buddhist reaction may be, "bring him on...give me a pic and I'll add it to my shrine".

In the future, I hope to add some photos to this page. I've been told of several fanatical Thais in Bangkok, wearing placards, sporting mini speaker systems, and warning of Armageddon. If you have any such photos, please send them my way!

***************

Dec 26, 2008: Oooh, Santa has granted my wish! With permission from the photographer, below are a couple shots of an aforementioned loonie. You see "Jesus is the Redeemer" in the first pic, and "The Result of Evil is Death" in the second.

Bolt Versus Phelps

As much as China's attitude towards Tibet digusts, there's no denying the successful, spectacular nature of the 2008 Olympics.

Imagine some new sprinting events. One would be a "chicken sprint", where the athlete is required to insert his hands into his armpits for the duration of the run. In another event, the hands must be held over the head with elbows locked. A locked-knee sprint could be included. How about one in which the athlete is required to raise his knees to the level of his sternum on each step? All of the above would have 100, 200, and 400 meter categories, as well as relays and medleys.

Perhaps a "silly sprinting" event would be overboard.



In any case, if such events were ever to be seen, would anyone be surprised to see a character like Usain Bolt walk away with, say, eight gold medals around his neck?

As absurd as the chicken sprint seems, isn't that what we have in the swimming events? There's the breaststroke, the butterfly, and the backstroke, with medleys and relays. Judges eyeball the contestants, prepared to disqualify any of them for breaking form. There's also the freestyle event. In the end, though, there's nothing freestyle about freestyle...the fastest stroke is clearly the American crawl, so that's what all freestylers inevitably use.

I don't doubt that hardcore swimming afficionados would be indignant about my take on the butterfly stroke. It's a uniquely challenging form with a long history (?), they'd say. But c'mon...when an Olympic athlete comes home with a hoarde of medals, he/she is most certainly a swimmer. Phelps broke Spitz's record for medal haul, which Ian Thorpe had threatened in Sydney. Isn't it obvious that there isn't any great separation of skillsets between swimming events?

As much as I like to see Phelps padding the American gold medal count, I'll cast my vote for Usain Bolt as the superhero of the 2008 Olympics. In the event that displays the rawest, most touted, most sought-after athletic skill (speed!), he easily annihilated the competition and the world record. Given his relatively poor explosion from the blocks, it's fair to speculate that somewhere around the 60 meter mark, he was propelling himself faster than any of the roughly 100,000,000,000 humans in history.

******************

Gymnastics is another sport where multiple medals are frequently seen. Here, the above complaint (of large overlap between skillsets in different events) applies, but perhaps less strongly. The problem with Olympic gymnastics is the fact that the athletes can only receive medals in particular events if they've already displayed competence in all four gymnastic events. To take this logic to an extreme, imagine that you can't enter the shot put competition unless you've already demonstrated that you're an elite decathlete. The talent pool of potential shot-putters is then slashed dramatically, and it would then be no surprise to see an individual medaling in both the shot put and the decathlon.

Gymnastics is spectacular, but can there be any doubt that it would be even more so if gymnasts were allowed to specialize in one event? In other words, an athlete could specialize entirely on the floor routine, foregoing the training required for the vault, balance beam, and parallel bars. In addition to an increase in the mind-bogglingedness of the performances, we might see a decline in some of the alleged abuses of young female gymnasts, who must maintain an insane training regimen to prepare for four events.

Frontloading, Freeloading



Today's organisms are phylogenetically descended from others which were vastly simpler than they are, so much simpler, in fact, that it's inconceivable how any kind of description of the later, complex organisms could have existed in the earlier one. John Von Neumann

There are numerous grades of creationist arguments, from those that willfully ignore the convergent evidence from multiple branches of science, to those that make every effort to conform to available evidence without dispensing of that added element, the cosmic designer. The notion of "frontloading" falls into the latter. The idea seems to be that:

*Evolution did indeed proceed from a primordial common ancestor.

*Further tinkering may not have been necessary, but the potential for all sorts of otherwise impossible complexity was built into the DNA from the very beginning. Over geological time, organisms unfold into more complex, higher forms. Evolution, in other words, was directed from the very beginning.

Typically, a frontloader gets excited if/when some journal reports on a gene that serves no immediately obvious function in a creature that resides in a low position on the evolutionary tree, but is important for higher organisms. An example would be precursors for nerve tissue found in some sponges. Unlike the folks who do the research and write the articles, these frontloaders are quick to speculate that the gene in question was somehow embedded for future generations and is worthless for the sponge.

Despite the attempts to move the ID goalposts right out of the stadium, there are big problems with frontloading:

1) Exactly how many genes needed to be loaded into the primordial organism to encompass all of life's diversity over the last 4 billion years? Presumably, any genes that IDers typically label "irreducibly complex" (e.g. those for the blood clotting cascade) must be included here.

Michael Behe takes a particularly, uh, nuanced view on the subject. Some of his remarks seem to suggest he's not averse to a frontloading scenario. And he claims to endorse "common descent". On the other hand, he also argues that the majority of the 10,000 or so protein/protein interactions in a typical mammalian cell exhibit irreducible complexity. That's just one species! For a Behe-frontloading scenario to work, tens of thousands of different protein coding sequences would have to be packed into the primordial organism.

2) How were these useless genes preserved over 3 billion years or more? Useless genes, of course, have a habit of getting excised from the genome, so we should see evidence of some sort of mutation-checking system that is so powerful that a wide variety of genes can be passed through trillions of generations without so much as a single base pair substitution. We don't see that, and it's not for lack of trying...biochemists would love to get their hands on enzymes that copy with such fantastic fidelity. It's funny to see the same folks who have offered up so much blather on the topic of "genetic entropy" reverse course and speculate that certain useless genes have been passed through lineages unscathed for eons.

Then again, there seems to be another breed of frontloader who argues that none of these ancient genes were actually useless. They simply served functions other than what we see today. That's great...it's the same argument that biochemists have offered the IDiots to dispute "irreducible complexity" for the last 20 years (e.g. on its own, the spring mechanism of a mouse trap won't catch mice, but it will serve nicely as a tie clip).

3) Where are all these buried genes now?

I can see some "outs" for the above questions. As for the buried genes, IDers can wiggle out of that dilemma by fantasizing that we've reached the evolutionary juncture where all such genes have been jettisoned and are thus, conveniently, not available for study. With the advent of humanity, you might say, all biological innovation pooped out. Awfully sci-fi.

It's possible to imagine some sort of DNA or RNA software package that compresses a huge diversity of genetic outcomes into relatively few base pairs. I'd call this program "evolution", but the frontloaders must also explain how their pet examples of "irreducible complexity" get compressed and maintained in the primordial .zip file. If you respect the authority of Von Neumann, that's one hell of a hurdle.

Should I try to make that bacterium sweat, or grunt with effort?

The Tedium of "Uncommon Descent"



I've been eyeballing William Dembski's "intelligent design" website, "Uncommon Descent". Speaking only for myself, there definitely is an enjoyment in sneering at these folks. It's not only a concern for the future of science education in the U.S. that compels me, all too frequently, to see what these folks are up to.

There is yet another motivation for visiting these sites. On some level, I honestly do hope that somebody could arrive at an argument for "intelligent design" that is compelling, or actually challenges some evolutionary views and forces good scientists back to the blackboards. I'm all for weirdness, whimsy, complexity, surprises, and strange twists. More than anything, I enjoy the attempt at honing in on reality. If science blows expectations, more power to it. Contrary to what many creationist ninnies seem to believe, there's no "anti-god" motivation behind my disdain for their philosophies, and that's probably true for most scientifically-minded people.

Unfortunately, these compelling arguments never seem to emerge. Visit the site, and it's highly unlikely you'll find anything of scientific value. Currently, what will you find?

*Philosophical proofs against anything that tweaks the Abrahamic mindset...abiogenesis (how can non-life beget life? huh?), artificial intelligence, morality (if there's no absolute lawmaker, people can just run amuck, right?), etc. Didn't these sorts of arguments lose credence 400 years ago?

*Disputation of the global warming consensus. This, of course, has little or nothing to do with the site's stated charter (to dispute "materialism"), but it's not in the least surprising to see where these folks stand on the issue.

*The "Darwin is the Jesus of Atheists" argument. Constant attacks on Darwin's character and intelligence.

*Praise for the way in which ID has subtly infiltrated society.

*A repeated argument that science requires more faith than religion. (Scientists assume that if you feel pain in your foot, you've hit a real rock, but religious folks don't need that assumption, blah, blah, blah). Ho-hum.

*Complaints about PZ Myer's threat to desecrate communion wafers.

*Praise for a journal article titled "Design Principles of Photosystem II and Hydrogenases". Like infants, it seems the IDiots are merely thrilled at the inclusion of the word "design" in the title, since the actual body of the paper contains no succor for them. This isn't the first time that the term "design" in a paper has incited an orgy for these fools.

*One of the main contributors arguing, in effect, that mutational hotspots somehow disprove evolution (according to him, they're entirely non-random, which is anti-evolutionary, blah, blah, blah). Tedious. Similarly, there's an emerging ID-based argument that epigenetics == Lamarckism != Darwinism, so evolution is false.

*Endless repetition of the "evolution is in its death throes" mantra. In the next paragraph, of course, you're likely to hear these dunces complain that they have no representation at all in academia because of one conspiracy or another.

*Interminable proclamation that any slightly perplexing biological mechanism is "IC" or "irreducibly complex", and thus impossible to arrive at by any means other than conscious design. The current example is the Venus Flytrap. At first glance, it is a tad imagination-defying that that such a mechanism could evolve. After all, what use is a half-flytrap? Five minutes of internet research, however, reveals that the flytrap is related to the sundew, a carnivorous plant that doesn't snap shut, but traps flies via a sticky goo. It's then fairly simple to imagine some gradual evolutionary steps...1) the sundew better captures prey by folding around it, albeit slowly, 2) the folding mechanism improves, and 3) the goo is eliminated. My initial failure of imagination is remedied with some simple background on the flytrap's relatedness to another species.

Where's the bloody science? What is a pro-ID scientist to do in a research environment? Shall scientists cease work on abiogenesis because an IDiot has a cutesy philosophical refutation of its possibility?

The UDers are known to imply that a number of their scientists are forced to work in stealth to avoid the bigotry of "big science". If huge numbers of biologists are indeed being expelled for their unorthodox views on evolution, it only makes sense that there should also be a sizeable number of scientists working stealthily on pro-ID science. You'd expect a slew of anonymous but science-literate posts over at "Uncommon Descent". But the tone of the posts over at UD make it clear that there aren't any such stealthy biologists contributing to the site. One of the head honchos at the site, in fact, is in the habit of announcing that he only has access to the abstracts of journal articles (i.e. he doesn't have the passwords that any university academic would).

One of the hallmarks of pseudoscience is a lack of willingness to entertain third explanations. If we can't explain the lights in the sky, then an alien visitation is the only possibility. Even if we grant the dubious premise that known mechanisms of evolution (e.g. point mutations) can't account for the complexity of some proteins or protein complexes, why not speculate on mechanisms by which evolution can proceed at an accelerated pace? I hint at a few here. Here's a prediction: if and when new explanations are validated, they'll come from real biologists. The findings will then be greeted with excitement by most academics, but will be pooh-poohed by the IDiots.

************

By the way, don't even attempt to post a comment on "Uncommon Descent". They'll ban any real scientist who evinces the slightest hint of snideness, though they're more than happy to let young earth creationists roam amuck on the site. In this sense, the site is all the more anti-evolution: the bright folks get weeded out, and the morons survive.
