Performance issues
Ruby on Rails is much, much, slower than I would like. It takes around .25 seconds to render the index page: about 10 times longer than Ragnar. I've alleviated the problem somewhat by switching to a Mongrel cluster with Apache's mod-balancer, but performance is still slow. I can't add any more foreign key constraints--pretty much every feasible relationship is locked down. I guess it's just down to ActiveRecord tuning, and figuring out how to make ERB run with any semblance of speed. Possibly memcached, too...
Anyway, sorry for the inexplicable downtime. Things are still moving around quite a bit.
Winter Term
So stuff here has been busy as heck the last few weeks. Classes are beating me up: Classical Mechanics, Ordinary Differential Equations, and Japanese 205 this term. Aikido hasn't been going at all recently, which is sad. First week I caught whatever cold was going around, then this Monday I knocked my shoulder out of commission on one of the 4th kyu sacrifice throws. It's slowly coming back, but I'm still not up to rolls, or really much of anything with that arm. Realistically speaking, I'm probably not going to test this mid-term: I've just missed too many classes.
This week was full of out-of-town visitors: Des and Bitsy came out here for the weekend, which was full of Aikido, reading, and photography. Bitsy helped me out with the alumni interview for Physics, which was more informative than I had initially expected.
When it came time to head back to the airport, Max, Des and I borrowed Pechous' car for the trip--or at least his keys. Turned out the car was across campus, encased in snow, low on gas, and incapable of starting. Luckily, as we were just about to give up, Chase arrived! He pulled out the jumper cables, which after extensive maneuvers eventually reached between the cars. We *still* couldn't get the car to start, so Chase kindly offered us his car for the trip. After he left, though, Max couldn't get the car started! I tried, but the keys just wouldn't move. As it turns out, starting the CRV requires focusing very intently on the engine turning over and rumbling into life, and believing the car to be in motion. After buying gas by committee, I restarted the car for Max, and we made it to the airport in record time.
That evening, Rachel's friend Justin showed up, which was a welcome surprise. The whole gang went to see Ebony on Thursday, which was amazing! Grace did an awesome job in On Pointe, and there was a brilliantly choreographed performance of Evanescence's "Bring me to life"... for three week's work, it was incredibly well orchestrated. Fun times. :-)
Eighth Weekend
Classes haven't killed me yet!
It's eighth week, and time for overdrive. Two take-home finals (one expected to take two weeks!), an ODE lab, an 80 hour final project for Computational Mechanics analyzing the dynamics of our tinkertoy siege engines, and all the regular Japanese and ODE coursework on top of that. Of course, this can only mean one thing: it's time to take harder classes.
So I'm registering (hopefully) for Partials, Electricity and Magnetism, and some mysterious third course. I'm thinking about Epistemology or Philosophy of Physics, although those courses fill pretty darn fast. Philosophy of Physics looks particularly awesome, talking about issues with non-locality, causality, and the far-out world of quantum. Only a few spaces left, so I've got my fingers crossed.
Broomball has drawn to a close: the aiki-fumitsubusu team "Harmony on Ice" made it to the playoffs and won our first two games 11-0, only to suffer defeat 0-4 in an intense match later that week. We really played well this year, coming together as a team over the course of our twelve games. I'm disappointed that we couldn't play more: Broomball has got to be the best winter sport ever.
Max and Sophie convinced me to follow them on Book Across The Bay, a 10 km ski race across a frozen lake at night. So I learned how to cross-country ski in a week, rode the bus up to Wisconsin, and found myself standing at the starting line of a vast frozen plain, lit up by an wandering path of candles in hollowed-out blocks of ice, stretching into the distance. Way stations handed out cookies and hot chocolate, and as Max and I passed the fifth kilometer, the first of the skiers crossed the finish line, made evident by a brilliant fireworks display. I'm really glad I got to go, and look forward to heading back next year.
Postprocessing
I sometimes wonder about how much postprocessing is, for lack of a better word, "honest", in creating a photograph. When working with an image composed of a bit vector, which is only interpretable through the use of complex hardware, I feel free to modify the image as much as desired; unlike working with a traditional negative, in which the image has a concrete physical form, one sequence of bits is, in some sense, as good as any other. This lack of permanency, of a link to the exposure itself, is in some ways liberating, but can also feel dishearteningly trivial.
For most images, I perform mild color (usually, just levels) correction, rotation, and cropping only. I feel that these modifications are not only traditionally acceptable, having analogous processes in the darkroom, but do not change the photograph in a way that misrepresents having been there. That is, I suppose, the most important aspect of photography for me: relaying the experience of seeing something in the world to someone else. Drift too far from that experience, and the photograph communicates a dream, not reality.
The funny thing is, I'm not troubled by paintings, sketches, or detailed computer graphics for not conveying reality. Likewise, I enjoy fantastic effects at the movies, where people interact with fabricated images so realistically that it is difficult to identify what in a scene actually existed in the first place. The idea that photographs, by virtue of their apparent realism, must somehow be constrained to that reality, is, when I think carefully about it, quite arbitrary.
Anyway, there are times when the image I want to create is factually accurate, but impossible to achieve without the use of significant modification. For example, this image of Vernal Falls is a composite of two matched exposures, one above, and one below. I was on a narrow trail inset into a cliff face, and didn't have a lens wide enough to capture the scene in any complete way. I took two carefully aligned exposures, overlaid the images in an editor, and erased the upper exposure along fault lines in the rock face and forest to combine the two. The resulting image is almost indistinguishable from what one would see if they were to stand on that trail, but it is not quite the same image: instead of having only minor color variations, the structure is different. Lens distortion makes such errors impossible to avoid.
What I wonder is, given how "true" the photograph feels visually, does it still communicate reality? How much change in an image is required before it no longer documents what is, and begins to describe what one imagines? And how much modification of that original exposure can I be comfortable with as a photographer?
Winter Term 2007
To sum up the last term:
I took three classes: Ordinary Differential Equations, Japanese 205, and Classical/Computational Mechanics, affectionately (though with a thin edge of nervousness) referred to by many physics majors as "Classy" and "Compy". These last two ate me alive: the average weekly problem set was 18 hours in length, although one went up to 25 hours. I spent a lot of mornings (9:00 P.M. -- 3:00 A.M.) in Olin, the physics building, staring at Mathematica and struggling through Lagrangians. "You know, the windmill is really pretty at sunrise," my friend Max told me. "You can see it through the windows of the Olin hallway."
The last two weeks of the term were consumed by a massive final project: building and modeling a tinkertoy siege engine with the use of Lagrangian and Hamiltonian mechanics. My partner and I wrote hundreds of lines of code, and dozens of pages of equations, trying to model the energy transfer between the pendulum falling and the motion of the wheeled base. The problem consumed my life; walking to dinner, waiting in line, even in other classes, I'd think about drag models, wheel inertia, and projectile efficiency. We worked somewhere around 60 hours per person over two weeks.
Then there was the take-home exam.
A 30 hour monstrosity--one problem, parts A through O, we wrote our own Runge-Kutta solver, derived Lagrangians and Hamiltonians, and non-dimensionalized the problem three different ways. By this point, eight hours of sleep a night was right out: I spent those two weeks doing coursework contiguously, with a one-hour break each weekend. Then, finally, it was done: the paper was finished, the model made accurate predictions, the powerpoint was finished, and we gave our talk. Maybe we did well, maybe not, but it was done.
There was another take-home for ODEs, and a Japanese final, but they didn't seem that hard. Everything worked out all right in the end. And, looking back, I'm sort of happy about the whole thing: much as I resented the professor at the time, he got us to accomplish some pretty incredible things. :-)
Other things happened, too: I was fortunate to play for two broomball teams: Harmony on Ice (the Aikido club), and Gays on Ice (self-explanatory, really). Harmony started out a little uncoordinated, but game after game we got better at passing, knowing positions, and controlling the ball. Joel-sensei is an astonishingly good player! We made it to the playoffs, and won our first three games 11:0. We were defeated in the fourth, but it was a great season. Totally ruined the knees of my pants, though: this summer, I'll have to patch them with something tougher.
After five terms of Japanese, I've decided to not take 206. It conflicted with Partials, and would have made made my schedule a lot harder. It's a tough thing to give up, though; I love the language.
I tested for pre-fourth kyu mid-term, and fourth at the end of last term. Despite messing up the timing of the buki technique (there were fourteen!), it went pretty well. Can almost do jump-breakfall #2 now. I'll be working on pre-third stuff most of Spring term, along with demo stuff for Ann Arbor.
Electrostatics, and Then I Found Five Dollars
A couple of funny things happened to me today. Over break I got a series of e-mails with tips for taking the Collegiate Learning Assessment, a scenario-based assessment of critical thinking skills. The names for each tip started with the letters B and S: "Be Specific", "Be Skeptical", etc.* However, the e-mail for tip number four was:
TIP #4: READ DIRECTIONS ($5.00 extra to anyone who can come up with a version of this tip's name that starts with an “S”) Check that you’ve done what you’ve been asked to do. If you’re being asked to play a role, think about who you are suppose to be writing for. Don’t assume that your audience knows what you’re writing about.
I fired back a tongue-in-cheek response, suggesting a bunch of S-phrases like "Satiate Curiosity", "Suppose Nothing", "Study Directions", and so forth. I didn't realize they were serious about the money, but a week later I got a response: they wanted me to stop by the Dean's office and pick up the five dollars. That was... rather unexpected. :-)
A while later, I was sitting in a CMC bathroom stall, reading the graffiti ("Kyia can't normalize a wave function", et. al.), and moved slightly to one side. Suddenly, my head prickled. Moving around, I discovered that there was an enormous electrostatic gradient between the two plastic panels of the stall. My conjecture is that when people take off their coats, the position of the door forces them to brush against only one of the two walls. Rubbing coats against the plastic deposits a large static charge on that wall, and sets up a strong field. Low humidity made it especially noticeable--moving my hand within a foot of the wall resulted in audible pops as the potential difference broke down the air. Yay electrostatics!
*Yes, I thought it was a poor choice for an acronym, too.
The Archives
I haven't taken many classes lately with research papers. It's all been problem sets, notes, finals... not much in the way of going out and finding stuff on my own. Because of this, it was not until yesterday that I experienced the awe-inspiring mass of documentation that is the U.S. Government Archive, on the first floor of the libe: rows and rows of compressed movable shelving, stuffed full of treatises on every imaginable topic.
They're filed according to some byzantine scheme, with at least six separate fields for each identifier. The notation uses capitalization, slashes, dashes, dots, colons, and even superscripts to index each document, and after perusing shelves of this stuff, I can't ascertain what those numbers mean. On this shelf, a decrepit tome "War" rests sedately on the shelf; thicker than it is tall, it describes the military capacities of the United States decades ago. Here's a report on global warming written in 2005: a thin paper booklet held together by staples, and right next to it: five volumes, over three thousand pages, detailing the threat of Communism to the American public.
There's an org chart of American Communism, with hierarchical boxes and arrows laying out the many attack vectors of the insidious Left Agenda. There are pages and pages of testimony before special investigative committee, in which politicians, actors, doctors, and professors testify that they have not been involved with the Communist cause. There are pages and pages about the Multinational Negro Commission, and the Communist Youth Outreach programs. There's discussion of legal proceedings: laws to outlaw the teaching of Communism or related principles in public schools.
Holding this book in my hands, I laughed. How funny, to think of Communism as a serious threat to the American life or government! And how unsettling, that we took it so seriously! What person nowadays would consider blacklisting someone from an entire profession, just because they happened to support a different style of resource allocation? Report one's friends or neighbors to an investigative committee? The fear of Communism, in retrospect, is comical, irrational, unsupportable. I want to say to myself, "Look how far we've come. This isn't an issue now--we're smarter, more experienced, less afraid."
I wonder if, in the future, we'll look back on what we fear today, and laugh. Will we be darkly amused at how we applied the word "terrorism"? Will we chuckle at ourselves for disputes over the teaching of evolution in public schools? And will we reflect on how we fought tooth and nail to withhold legal benefits from same-sex couples, smile, and think "I'm glad we're over that now."?
Weekend, Tests, Genyokan Trip
The weekend was pretty darn awesome. Sophie and her housemates invited Nik, Max, Rachel, Anna, and I to dinner, where they'd made tons of delicious Jewish food. There was salad, fresh-baked bread, delicious kugel, and a massive roast with carrots and other veggies... it was *soooo* tasty! After weeks of Sodexho, getting to have a real meal with good company made my day. Max and I washed the dishes, and after we hung out on the couches, studying and watching Grey's Anatomy.
The two tests from Monday's classes went okay--I was definitely more confused by the EM material than Partials. Of course, the Partials test didn't actually ask us to solve any PDEs, and that's the part of the course I totally don't understand yet, so I got off easy. Seeing the unusual connections between function spaces and Linear Algebra is mind-bending at times.
This weekend is the Genyokan trip! Ten of us are packing into Sophie's car and Joel-sensei's van, and driving up to Ann Arbor for the weekend. Unfortunately, we're leaving Thursday night, so I've got to get all of Friday's HW done by then. There'll be classes, clinics, and the demo, which we've been preparing for every class of the last two weeks. I'm really looking forward to going--I didn't make the trip last year, so this will be my first time.
Fire Alarm
Two hours after going to sleep, I awoke to a shrill alarm with a start, kicking off the bed and into the air. Three things went through my head in the second or so before I touched down.
- Hmmm, that's not my alarm. It's much too high-pitched, and isn't intermittent.
- Gosh, there's a lot of smoke in here.
- Hey, is that the ground?
"Wow, it must be a fire. As in, stuff is actually burning," my sleep-addled brain mumbled to itself. "I guess if the building is going to burn down, I should probably grab my EM homework. It would really suck if that went up in flames and I had to do it all over again before Friday." Pulling on my bathrobe and grabbing the backpack which contained the precious homework in progress, I checked the door for heat, made my way down the stairs, and out into the cool night air.
About five minutes later, I remembered that this is Minnesota. Even though it's spring, the nights are still pretty darn cold. While I appreciate my half-awake self's efforts to preserve the academic parts of my life, next time, I really would appreciate it if he'd grab something warmer.
Eventually, Security declared a burned pizza the source of the smoke, and we all got to go back inside. Didn't sleep too well, but at least it was an exciting night.
Genyokan Trip
Wow, that was a good weekend. I'm sore, and twisted my toe on the wrestling mats, but learned a lot. It was fun to be exposed to so many new techniques: all-direction step-in-thrust, a rotating takedown from side strike, and an opposite-hand variant of the fourth-kyu 180-degree pivot shuffle cross-step-under initiation. There was even koryu buki study, and some calligraphy practice! The demonstration itself went well too, although we didn't get to go through all six techniques.
I was happily surprised to see David-sensei and a bunch of other friends from the Portland club at the Genyokan. I miss those guys out here, so getting to work with them for three days was a nice reunion. Looking forward to getting back for summer, and having class with all of them again.
After being sick, it was nice to get back to doing all three classes, and then conditioning the next day. I've started to work on jump-backs with Nik and Sophie, and also jumping over partner. It's definitely difficult, but I'm hopeful they'll get easier.
In Which Math and Physics Continue to Freak Me Out
So last night, Nik, Max, and I were studying for the philosophy midterm, and we got to talking about the Monty Hall problem. It goes like this: you've got three doors, behind one of which is a fun prize, and behind the other two are nothing. You guess one of the doors, in an attempt to obtain the awesome reward, but before you get to see if you were right or not, some punk named Monty opens a different door, and shows you that there is nothing behind it. You then have the opportunity to change your selection. What do you pick?
Well, we figured, being shown that another door has nothing behind it doesn't change what your original choice was, so it doesn't make a difference as to which door you pick now. Either of the remaining two doors will be equally likely to have the prize behind it, right?
Nope, I was wrong.
It's always to your advantage to switch. It's totally screwed up, but choosing the door you didn't select initially always has a higher probability of success. When you make the initial selection, you've got a 1 in 3 chance of choosing the right door. When one door is eliminated, the remaining problem is 50/50. So here, it makes sense to make a new random choice, since you've got a 1 in 2 chance of winning. The weird bit is: it's more advantageous not to choose randomly, but to always choose the other door. I still don't get this at a gut level, but I suspect it's because selecting randomly, you're less likely to choose the same door twice, so sticking with the original door is actually choosing the less successful route. The other way I can look at it is that there's no penalty for switching: being unable to distinguish between the doors, choosing a specific door each time doesn't decrease the randomness of your selection, so you still get the 50% chance.
As if that wasn't weird enough, Adam joined in, and blew my mind a second time. When you're doing NMR, he says, a longer sample time increases the effective resolution. So, running a 30 second scan yields more finer detail than a 5 second scan. The weird bit is--the data gets noisier over time. It actually turns out to be advantageous to not run the full 30 seconds, but to take 5 seconds of data, then fill in the rest with zeros, and claim the signal died off. When you do this, and run the FFT, the resolution is higher. Not just higher than the normal 5-second sample, but higher than the full 30 second dataset. You can see finer peaks, by inserting null data!
It gets weirder yet. Because they need to cover a wide range of frequencies, but the machine can only emit a specific frequency at a time, they set the frequency to the middle of the range, then make the pulse time really short, such that the actual frequency isn't resolvable. Because of the Heisenberg uncertainty principle, that single-frequency pulse actually covers the entire range, and you get back a full data set for every frequency. How unbelievably weird is that!?
I think MacCallum is right: QM does beat any tendency towards realism out of you.
Adventures in Faith and Sexuality
For months now, my friend Justin has been trying to get me up to the cities, and, more importantly, to meet the people on the Equality Ride. While I can't hope to express what the ride is without having been on it, the best story I can offer is that of 50-odd young adults traveling around the country on two buses, going to college campuses which make life hard for Lesbian, Gay, Bisexual, and Transgender people. Some universities have policies so severe, students may be suspended or expelled for supporting their gay friends or family. The ride aims to change this by, well, talking. Talking to students about their experiences with sexual and gender identity, explaining how their faith interacts with those, and challenging arguments that these identities are fundamentally immoral.
The other half of the ride is more a public relations effort: when schools refuse the ride access to campus, riders stand vigil at the sidewalk, walk around the campus borders, or deliberately trespass. At one stop, riders carried pictures of their family. At another, they left lilies to symbolize the suicides of LGBT students, and read those stories aloud. "All we want to do is talk," the campaign seems to plead, "and yet we are handcuffed and arrested because the school doesn't want their students to have this dialogue."
While I agree wholeheartedly with the Equality Ride's efforts to talk with students, this method of civil disobedience rests uneasy with me. I think it's disrespectful to invade a private property, especially as a part of an organized group. These colleges have the right to bar people from their property, and, perhaps to a lesser extent, the right to determine a code of conduct for students. Surely a college can enforce its own attendance criteria: for example, as a man, I wouldn't complain about being denied entrance to a woman's university.
Despite my concerns that the Equality Ride might be too aggressive in its push for social justice, the opportunity to spend a weekend in the cities with them sounded too good to pass up. While I wasn't able to make it to the final official stop at Mankato, I could still join the riders as they tied up loose ends from the trip. Here was a chance to get out of small-town Minnesota for a few days, make new friends, and try things I'd never experienced before. "And hey, with down time," I thought, "I might even get that paper on spectrum allocation written." I had some concerns about the trip, though. Without ties to any sort of queer community or political movement, what common ground would I and the riders have? As someone with no commitment to a specific faith, would I fit in with a primarily Christian crowd? While I resolved to keep energy forward, I didn't know at all what I was getting into.
It's Friday, nine o'clock, and I'm lugging some clothes, blankets, and gear down to Justin's van. He's tired, having missed the exit by about 30 miles, but warms up when we get to talking on the way out of town. He shares some of the ways the two months of the ride has changed him, and it's evident in how he speaks about the stops. He's become more self-sufficient, convinced in the intrinsic worth of people and the independence of their actions from character. He talks about the importance of loving the people he talked to on the ride, even when they said he would never be accepted in heaven, or that his existence is an outrage in God's eyes. I'm reminded of Ueshiba-sensei's assertion that "true budo is a work of love," and reflect that expressing compassion for those who mean us harm is a beautiful virtue. It's not enough to either strike back, or to stand there and take the damage. Blending with one's attacker, redirecting that aggression, and maybe saving both lives, feels more complete: a truer expression of love.
We arrive at a mid-size hotel, in what looks like a warehouse district. Things are a little broken down, a little edgy, but there's a current of life to the place. I sweep through a blur of faces and handshakes, and realize that people here are often... different. It's in the clothes: on some more grungy, on others more dressy, and in most cases tighter. It's also in the hair: girls have short, even shaved, hair; or flash vivid colors like (my personal favorite) coppery orange. It's in the piercings and tattoos: bars, rings, and zig-zags of metal adorn ears, lips, and noses. I feel concern as memories of flying towards the mat face-first bubble to the front of my mind, but reason that such injuries must be rare or preventable. Still others look entirely "normal": I couldn't pick them out of a crowd in any way. Gradually the unexpected differences normalize, and fade behind the faces of the people themselves: tired, outspoken, joyous, relaxed. Many are pleased to meet me. "We've heard so much about you," they say, and I find myself grinning back as I say hello.
As we join conversations in the lobby, the hotel hallway, and the street corner, the people I talk with are open, individualistic, and connected to one another in a way that doesn't exclude me. Somehow I'm at ease here, as I find myself enthusiastically contrasting Japanese and Chinese grammar with two young women, or listening to the discussions of the night's plans. Having spent the last two months under schedule, they're excited to spend the next few nights free: some look forward to drinking and clubbing, while others will spend the night indoors, seeking quiet. We go walking down Hennepin Avenue, a street lined with dozens of theaters mixed with bars and clubs. As we walk, we get glances from "family", as they're called here, and straight people alike: sometimes gawking, sometimes friendly. As someone who doesn't express many gay markers, most people don't recognize me as such, and I'm usually treated just like anybody else. Walking with this obviously queer group, though, colors me as the member of an unusual culture: shared for some, an out-group for others. In turn, it's fun to play the game of guessing who falls into which camp, and enjoying the open secret. "Oh yeah, they're definitely family," we good-naturedly comment as two 20-something men drive past. One doesn't have to look hard: the atmosphere here is one of relaxed permittivity, and guys walking hand in hand are everywhere you look. While others continue on to the clubs, I head back to the hotel for sleep.
The next morning is characterized by family in the traditional sense: Justin's parents are in town, and they kindly take us out to breakfast at a small suburban restaurant. The two of them are beaming, tanned, and enthusiastic about their son's efforts. I wonder if my dad will someday be as comfortable. We're joined by Linda, a friend of the family who expresses a youthful sense of humor and commitment to music--she's involved with at least one band, as far as I can tell, and keeps us up-to-date with the stories of recent concerts. I respond to the initial questions of what I study, where I work, and so forth. Mostly, though, I listen and try to track the conversation as they discuss plans for upcoming weddings, music drama, and family history. I don't contribute much, but enjoy following the ideas, and eating good food. Afterward, we walk back to Linda's apartment and discuss the Equality Ride, civil rights, and the Bible. I pull out my camera, and get a few good shots along the way: my favorite, of a wooden barrel, is filled with the new warmth and greenery of spring. It's a feeling that suffuses the whole morning in my memory.
The rest of the day blurs by. I snag a few hours nap, recovering from a week of late-night homework. Head down to the pool and hot tub, and enjoy swimming for the first time in months. There's a good deal of splashing and laughter, and I discover a lot of Aikido doesn't make sense when floating. Refreshed, I tag along on a visit to a local colony of Justin's fraternity, and for the first time come into contact with the Greek system.
At first, I can't get over the fact that this campus is BIG. There are perhaps 30,000 students here, which makes the university fifteen times larger than my college. There are blocks and blocks of houses with students out front, on couches and chairs, at tables, dancing. Everyone seems to have a beer in hand--bottles and cans are stacked on all surfaces. On lawns and down sidewalks, boys throw footballs or, more rarely, Frisbees, and I feel the impulse to lay out for a disc. Music rumbles out of performance speakers: a mix of bumping hip-hop and danceable party tracks. The target of today's expedition is a three-story stone house, built perhaps in the early 1900s. We intercept a small group of students returning to the house, introduce ourselves, and ask for a tour. Along the way through the house, we ask about house activities, membership, and plans. I'm surprised to hear that there are only two minority students in the colony, out of perhaps thirty. To judge by the attitudes of those we talk to, everyone here is white, Christian, straight, and has money. It's obviously not true for everyone, but I'm taken aback at the norm. Afterward, Justin explains that while the selection bias is much weaker than it used to be, the accumulated stereotype persists. Hence, many fraternities have trouble finding minority applicants.
Justin and I go walking downtown at sunset, and I grab my camera. The light is fantastic, a warm sunset throwing the blue glass, gray concrete, and steel beams into relief. While I got some good shots, they didn't capture the warmth of the evening. We sit at a table outside the Lyon's Pub on Sixth, and enjoy a hearty meal. I encounter spinach and artichoke dip for the first time, and savor the taste of warm flatbread. The waitress is amazing, too; good timing, friendly, and ready with recommendations. Seven dollars buys me a delicious turkey sandwich--I'm happy for the night.
Back at the hotel, I sometimes have trouble blending with my new-found companions. Smoking is remarkably prevalent, and while I want to keep talking, I'm sometimes forced to seek cleaner air. Other times, I'm unsure what pronouns to use--appearances can blur the line between male and female, and the opportunity to ask is not always available. At times, I find more flamboyant personas obnoxious, and have to remind myself that yes, demeanor varies, and it shouldn't get on my nerves. As I get to know people better, I find the speech patterns less unusual, smoking tolerable for short periods, and questions of male or female become irrelevant. Real people start to emerge: I discover Delfin shares with me a love of photography, and learn about his plans for graduate school. Talking about the stops, too, yields a further appreciation for character. I've heard it said that my generation doesn't get up and move, doesn't write letters or protest for causes we believe in. Discovering people my age who do have a cause, and can speak eloquently and respectfully for it, is heartwarming.
A few hours later, I squeeze into the van with eight riders. They're headed to a nightclub by the name of Pi--I've halfway promised to explore the fraternity party instead. The whole van sings along to the music as we drive, and groove in their seats. The words and rhythm are unfamiliar, energetic, sexy, and hard to take seriously. It's still a good time, and as we pull up to the curb, they tumble out of the van doors in high spirits.
Returning to the fraternity house, we find that the night has brought crowds. They fill the deck and yard, talking and drinking. Guys with arms around shoulders, girls huddled over their cell phones, everyone with a drink. I try to reverse-engineer the handshake patterns, but miss a few steps. The empty living room is packed with dancing students, and downstairs 50-odd people are crowded around game tables. I catch bursts of conversation, banter, shouts. Homophobia is loudly expressed, which confuses me as I watch guys in constant contact with each other. It's okay, I surmise, as long as it's between brothers. On the dance floor, a girl tries to catch my attention, and I turn to say hello. Loud music blasts our conversation apart, however, and she signs apologetically, "I guess we won't be able to talk." Disappointed and displaced, I slip away from the house to walk for space and air.
I may not be a part of this culture, and I don't think I want to be. Still, there's something to it: being drunk, dancing, and at the same party is all they need to feel a connection and get to know each other. There's a sense of real comraderie, too, between members: it's visible in the way they greet each other, the banter, the relaxed but present power structure. People here belong. Sure, the smoke and fury was too much for me, but I'm glad I got to visit.
Sunday is filled with work: I help set up the meeting space the ride uses, then take my camera and go walking. I'm looking for a coffee shop to grab some food and download some sources for the paper, but after an hour's travel, reluctantly conclude that downtown Minneapolis is not going to be helpful in this quest. I think about how in Portland, one couldn't go two blocks without finding a coffee shop or park... and settle for a Borders cafe. With sources downloaded, I make my way back to the hotel, and sketch out arguments around the privatization of radio spectrum. The hours fly by, and I enjoy hanging out on the back patio, drinking water and socializing while we write.
At six, we leave for dinner. Haven is hosting a party at her house, and the 26 west bus riders walk a few miles across the Mississippi to the suburbs. The evening is warm, and the sun diffuses through the clouds in hues of purple and orange. I'm full of energy, and can't resist jumping onto the sidewall as we walk, admiring architecture, sharing life stories. Haven's home is a small white house in a quiet neighborhood: few fences between the yards, and aging rockery says "this place is an old home." As we hang out on the lawn, eating curry and salad, I listen to the riders' experiences at stop after stop, of being directed to a fenced-in "free speech zone" on campus, of being arrested for carrying pictures of their parents, of finding the bus paint-balled and scratched by keys. They tell me about the police chief who, required by law to take the riders to jail, still brought fried chicken to the rider's community barbecue that night. I wonder how I'm going to make a difference in the world.
Walking home, I spend a lot of time talking to a rider named Matt, a former student at Brigham Young University. He asks me, "how do you identify," and I have no idea how to answer. "As a person," I eventually respond. "I mean, sure, you can apply 'gay' as a label for convenience, but that doesn't define me any more than 'student' or 'frisbee player' does." We have a lot in common, I discover: books, social scenes, interaction styles. For a while, I'm eerily convinced we're clones, but some differences become apparent: for example, he comes from a strongly Mormon background. As he tells me about going to school at BYU, I reflect that there is one story that all of us share, but is different for every one: that of coming out. Sometimes it's quiet, other times dramatic, but I haven't heard the same one twice.
It's about 10 o'clock, and a half-dozen riders have asked if I'll be going to the clubs with them. "Sure," I say, not really sure what I'm getting into, but resolving to keep energy forward. I grab a black short-sleeve dress shirt (one of two nice shirts I own), and move to iron it. "No, you don't understand," they explain. "You don't WANT to look nice. It's a good shirt, but don't iron it! No, you shouldn't wear anything under it. Trust me, you don't want to." Bemused, I concede such decisions to the professionals, and we walk out into the night.
Our group chooses the Saloon, an establishment flagged by a tall image of four young men embracing one another. Smokers stand at tables along the side of the building, talking and watching passerby. The bouncer at the front is surprised when I cheerfully inform him I won't need a wristband; perhaps, I think to myself, he's taken aback by the honesty of someone under 21. I walk through the small l-shaped entrance, and into a large, dark room filled with people of all shapes and sizes, some dancing, some standing at the bar, others watching the crowd or the shower--a plexiglass box, elevated at one corner of the room, containing a single shower-head. Inside, a man wearing next to nothing dances, showing off his physique for the crowd. It's not really sexy, but hard not to watch.
A cursory tour of the building traverses four principle rooms, two mainly bars, one for dancing, and one for games. I seek out people I'm familiar with, dance a little, and talk as I can. The music is an unexpectedly eclectic aggregate of styles, ranging from pumping rhythm and blues tracks to upbeat sixties pop. I'm not really sure what I'm doing here, besides being present. Yeah, I can do the bump-and-grind dance, but it's not really my thing. I can lead basic waltz, and follow swing on a good day, but that's not the style of the place. There's nobody I can aiki-dance with either, and I don't think anybody here would know how to react to front strike from under.
The look comes back here: I spot guys who turn around in their seats to follow me, some who seem almost ready to ask me something but turn aside, or just keep looking over from their friends. Some are good looking, but I'm not here to meet people. One sketchy 40-something comes up to me, and in a flouncing lisp informs me, "I just wanted to tell you that you are the cutest thing in this whole place!" He leers a little. I smile broadly right back. "Osu! Thank you very much!" I reply, and bow. He tries again, but I remain enthusiastic, friendly, and utterly non-sexual. Confused, he leaves me alone. Another guy follows me down the hallway, explaining, "I'm stalking you." I'm wary as I rejoin friends, and when Justin bumps up against me, I reflexively turn to side-step-in-throw. "Sorry," I apologize, "I didn't realize it was you." He laughs, and I relax again: being sober and with good company, I'm safe here.
Eventually, I find a comfortable space. At the bar in the back corner, Mike, Cylest, Jillian, and I wind up talking about where we're from, how we got here, and where we're going. I learn that Mike grew up in a strongly Mormon community in Alaska, and had to grapple with his church's belief that his sexual orientation was irreconcilable with Christian morality; that Cylest joined the ride as a straight ally, and found herself coming out over the course of the ride; and that Jillian looks forward to rejoining her son in California, where she'll work as a national park chaplain for the summer, leading services in nature. They ask me where I'm from, what connects me to the ride, and about Carleton. As we talk, the bartender asks who we are and why everyone here is connected. We explain about the ride, and he offers a free shot to all. We go home happy, tired, and some a little intoxicated: concerned for safety, I chase down one rider and walk her back to the hotel. It's a good finish to the day, to help someone get home safely.
The following day is dedicated, as Monday of mid-term break often is, to work: reading secondary sources and mostly finishing my Electricity and Magnetism term paper, in between meals gathered from the massive table of snacks and sandwiches. I spend some time watching the thunderstorms gathering from the hotel deck, over a quixotically poignant landscape of rusted billboards, dilapidated warehouses, and high-rise apartments. The riders are busy writing: personal notes to each other in hand-labeled journals, postcards to donors, or evaluation forms for their group leaders. Matt says to me "I know you don't have a journal, but I wish you did, so I'm going to write this for you." I borrow pen and paper, and write a note back. It's an unexpected and heartwarming expression of inclusivity--even though I didn't go on the ride, I'm still a small part of this journey.
That feeling is redoubled when I'm invited to stay for the closing ceremonies. I help set up the sound and projector for slideshows, and take in the visual history of the East and West buses. Some images impress themselves deeply into my memory: two riders holding hands, in front of a sign which announces "no trespassing"; a field of lily blossoms scattered on grass, with riders being solemnly led away; brightly colored prayer quilts abandoned to the ground, their bearers gone. I see snapshots of wacky humor, depictions of poignant defeat, and photographs of joyous reconciliation. I think these images, more than anything prior, convinced me that the Equality Ride is something powerful, something beautiful. Maybe I don't agree completely with the implementation, but I think it's still important.
As I talk to Shawn, he echoes some of my concerns. "Although we always say that it's not our fault, that the schools choose to arrest us, they could just let us onto campus, that's not the whole story. We do push the issue. We're the ones who decide to go on to their property, like it or not." It reawakens a question I had at the beginning of the weekend: is this sort of disobedience worth it? Are the lives that the ride changes sufficient cause to disrespect the rights of these schools? What if one prevents a suicide? Can the potential to save a life justify the invasion of private property? It's unclear to me, but listening to each rider in the circle share their final thoughts and remembrances, one possible answer emerges: this ride has changed us, and what we have done together has mattered.
Hypnagogic Synaesthesia
Over the past three terms, I've become aware of a strange connection between sounds and visual images in my mind. When lying in bed and trying to fall asleep, with my eyes closed and thoughts mostly empty, I frequently experience visual patterns in response to loud or sudden noises. The first time it happened, my roommate's Macintosh computer emitted an unexpected and loud 'bonk' noise as an alert. Simultaneously, a diagonally oriented field of wavy white and black lines flashed before my eyes. The intensity of the pattern varied smoothly from black to white, so no clear delineations were perceivable. I estimate that there were about twenty to thirty of these lines visible, to give some representation of their density.
The perception lay somewhere between reality and imagination; not a concrete object in the world, but also not a "minds eye" sort of projection. It's analogous to the experience of seeing whorls and cascades of shadowy color when you press on your eyeballs for a few minutes, except it occurred suddenly, and faded as quickly as the sound. It also feels like there's an extra component to the experience, as well: it's not just a field of lines, but a visual feeling of orientation. That bit is much harder to describe or even verify, but it does seem present.
At first I thought I was hallucinating, or deceiving myself. Yet the experience surprised me time and time again, and has been consistent: it's happened twice this week. Door slamming, alert sounds, even ceramic mugs being set down on a wooden desk: all have associated unique visual patterns. The intensity, orientation, density, and waviness of the lines seems correlated with the character of the sound: the mug, for example, evoked a short-lived, vertical, dense, and straight field of lines. Sometimes I see cross-hatching, or a simple uniform flash. I plan to record these experiences from now on, and will try to characterize the relationship in more detail.
I wonder if this happens to anyone else.
June 1st 2007: Andy Howe confirms that he also has noticed cross-hatch patterns with loud noises before sleep.
Summer
So, I'm back in town! That was fast!
Managed to get out of school okay: finished my two papers on time, and despite my notes disappearing managed to make it through finals without too much difficulty. The papers are actually pretty cool: for Philosophy of Physics I got to look at two accounts of the mass energy equivalence relation, and talk about how we revise the scientific process for education. I didn't get to explore that thread as much as I would have liked, but I did get to read all of Einstein's work on special relativity. I know it's been said before, but the guy's a genius. The reasoning itself is straightforward, but he makes these intuitive jumps that are very surprising unless you know where he's going.
My roommate for spring term moved out early in finals week. Or at least, he himself moved. Most of his stuff stayed behind, and the friends he said would come pick it up never arrived. Hence, at 22:00 the night before flying out, I found myself reluctantly dropping cubic meters of clothes, games, books, and food down at the Lighten Up donation area. That was kind of a tough break, and I hope his friend manages to save my roommate's stuff in time.
I did, however, manage to find space for almost all the room stuff! Sophie kindly let me put some oversized items (buki, lamps) etc. in her basement, and Anna will be taking some of those for the summer, now that she's got her new apartment. I did have some problems with shipping boxes home though: just before hopping on the bus to the airport, I found a package slip in my mailbox. Turned out my computer never made it off campus: the UPS folks dropped it right back off across the street! Lucky for me, the nice guys at the post office have said they'll make sure it gets back to UPS, and it should arrive in a week or so.
I encountered mono somewhere early in the term: that knocked me out of Aikido and pretty much all physical activity since fifth week. Most of the symptoms have faded by now, and I only get tired if I push myself physically. Unfortunately, "pushing it" now means something like running three blocks. I've been taking pretty good care of myself, getting lots of sleep, and hope to return to normal operations as soon as possible.
Or do I?
Typically, I'm averse to risk. I plan things carefully, deliberate on important choices, and get my work done on time. That's good, but I also I got stuck in a rut: wonderful as familiar friends and activities are, I feel great when trying things I've never done before, going on adventures, and learning new people, places, and cultures. There have been some pretty cool adventures this term: the Genyokan trip, the trip to the cities over midterm break, learning to fire a bow at an 1800s rendezvous... it's been really darn awesome!
So this summer, I'm resolving not to live the same week over and over again, and to get out there and have irresponsible adventures. I've no idea where I'll end up, but I do know it will make a great story!
Zoobomb!
"Zoo-zoo?" A grungy, bespectacled young man to my left shouts across the train platform. A cyclist, rolling idly down the street on what is perhaps the smallest bike I've ever seen, takes notice. "A-zoo-Bomb!" The youth next to me concludes, and the two of them wave to each other.
"You going to the pile?" The first inquires.
"Yeah, I'm gonna hang there for a bit, and I'll be up for the first run," The cyclist drawls.
"Peace," he salutes, and turns to the bemused girl between us. She's adjusting her glasses as if ready to ask, but isn't sure what kind of weird answer she'd get back. "Any time you see someone on a tiny kids bike on a Sunday night," he explains cheerfully, "Chances are they're going on Zoobomb."
"Zoobomb? What's that?" She asks, now alive with curiosity.
"Basically, a bunch of us take, like, every kind of bike imaginable, ride on to the MAX, and we get off at the Zoo stop, you know? Yeah, like 500 feet underground. Then, we cram ourselves into those elevators, and once we're at the surface, climb all the way to the top of the hill. Then, at about 10:30, we all ride down, like 100 bikers in a massive pack, craziest thing you've ever seen in your life. We blast down that hill at 30, 40 miles an hour, in the dark, on these tiny little bikes. It's unbelievable."
"So," She pauses, uncertain. "What's it like? To go down the hill, I mean."
"Life changing," he grins, and hops on his bike. "You gotta try it someday!" She looks intrigued, but has a train to catch. I, on the other hand, know I've found exactly what I'm looking for. Four years ago, my swashbuckling friend Ryan told me that I needed to go on this crazy bike ride myself. I turned him down at the time, but now I'm here to try it at last. Jumping on my own bike, I follow the first rider down to the Pile.
It's both unconventional sculpture and flagrant abuse of an perfectly innocent bike rack. The Pile lives up to its name: roughly 20 kid-sized bicycles lashed ramshackle to a single steel bar. As if on cue, a throng of Portlanders rise from the Rocco's Pizza across the street, and wheel their bikes to the Pile. Over the next half hour, dozens of cyclists arrive, as colorful and unique as their unusual vehicles: minibikes, BMX bikes, double-high frames, road bikes, and skateboards. Some come with extra wheels for stability when crouched to minimize drag, others sport six foot dragster-like front forks. There are zebra stripes, mismatched wheels, and sparkling tinsel through wheels.
The riders themselves are mostly young, in their teens to twenties. They wear worn jackets and torn T-shirts, show off punk hairstyles, or pierced noses. One boy about my age sports a black underarmour shirt, full-face motorcycle helmet, elbow-pads, and bright blue pants which reveal tough-looking armor plating where the fabric has worn through. There are a few incongruously proper business-types in their forties, but the norm here seems comfortably iconoclastic.
One young man takes charge of the Pile, asking everyone without a bike to step forward. He has them sign off on a clipboard, and distributes emergency kits to those with medical training. The rest of the riders check their bikes, admire the latest modifications and finds from garage sales, and discuss recent cycling events. "Were you there at the naked party? They had me doing handstands on my bike, junk hanging out to here, man! It's like 'Whoa, don't slip up', yo!". A young man (bearing a more than passing resemblance to a hobbit with his cape) casually strips and repairs one of the Pile-bikes in less than five minutes. Troubles resolved, he hands the bike off to a waiting rider, and the call goes out: we're on the move.
I can't help but grin as we proceed up the pavement, a swarm of cyclists two blocks long. We flow across streets, up hills, a liquid which defies the natural downhill teleology. We split apart when traffic intercedes, but pool together once at the MAX stop. Then comes the squeeze: the train arrives, the doors slide apart, and a hundred bicycles with riders are sucked into the light rail car. We're amiably compacted, elbow to spoke, careful to keep greasy tires out of the faces of other commuters. For the most part, those already on the train are unfazed: ride the MAX in Portland, and you'll see this sort of thing on a regular basis.
The train edges out of downtown, and picks up speed as we barrel into the tunnel. We're deep under the West Hills, and the ethereal howl of the tracks permeates the train. After a few minutes, we slow to a halt, and the doors open. Riders spew out of the packed cars into the underground station, waving their thanks to the driver. Again we play the jigsaw puzzle, this time cramming twenty-odd bikes into the giant elevators at the end of the station. It's a good chance to get to know your fellow Zoobomber, as you help them hold their bike overhead. We rise up, counting off the 260 feet, and emerge exuberant into the cool night air.
Now the ride takes on an edge of something secret: without apparent organization or direction, we walk, ride, and hike up the hills around the zoo, arriving at the top just as dusk falls. There's down time: riders talk and drink, and loose smoking circles aggregate. Finally, there's a proclamation: "FIVE MINUTES!" We huddle round for a quick introduction to Zoobombing protocol--how to warn other riders of traffic, the proper way to announce intention to pass, and a description of the route. "If you get lost," our educator slurs, "Just head downhill."
Seems simple enough, and five minutes later, I'm holding onto my bike, surrounded by hundreds of unconventional cyclists, counting down the seconds. "Five! Four! Three! Two! One! Zoobomb!" We shout in unison, and set off down the hill. As we pick up speed, the surrounding riders start to feel like a stationary frame of reference: it is the rushing gray asphalt, lit up by dozens of high-intensity bike and helmet lights, that is moving beneath us.
"Passing on your left!" I hear a shout being me, and maintain space for them to ride through. Seconds later, a woman in her forties on a tough-looking mountain bike blazes past, her broad grin a blur. "Zoobomb!" She shouts, and I echo it back to her. We're yelping, shouting, exuberant as the road bends and twists through the night. Each curve brings an exhilarating burst of speed, as we corner hard into the road.
Up ahead, riders shout out a warning. "Car!" It's a signal that a vehicle is near, and sure enough, just past the next turn an SUV idles. Its lights flare brightly and make it hard to see the road. "Car!" I shout, doing my part to warn those behind us. Most drivers just stop when they encounter a Zoobomb: there isn't any other safe option. Cyclists break and flow around the vehicle like fish around sharp coral, rejoining on the other side with whoops and grins.
At the base of the hill, I see the group slowing to a stop: we've reached the halfway mark, a cemetery drive just off the main road. "WOW!" the curly-haired college student to my left is overwhelmed. "Did you see how fast we were going?"
"Naw, you guys are slowpokes," the second man on a tandem-bike team contradicts. "We made it down here *way* before all of you."
"You're the blind biker? Seriously!?"
"Yep, legally blind. 'Course, my partner here isn't, he steers for both of us. But you get two guys pedaling on a single frame, and nothin's gonna catch you." I want to ask how they do it, but I'm interrupted by the start of the second half.
"Pick whatever direction you want, and go!" A voice shouts out in the dark, and I follow the cyclist ahead of me. "Stay out of the center," is all the warning I get, before we plunge onto a narrow, broken-up, U-shaped path: more a trail, really. The asphalt has ripped and cracked in the center, and my bike shakes violently--before I know it, my light has slipped free and is hanging loose from the handlebars! Following the riders in front of me, I dodge rocks and puddles as we barrel through the woods, finally bursting free into downtown streets.
Luckily, there's nobody behind us, and our stream expands to take over both lanes. Cars ahead of us come to a stop, and we whiz past. At each light the front riders shout the status of the intersection: "Car!" indicates cross traffic, while "Clear!" indicates it's safe to enter. Some runs are timed; the Zoobombers count down from red to determine when to start their approach, and make every light. On this route, there's no way to determine the state of the lights, and I feel lucky to make the greens. We finally coast across the PGE Park triangle, and arrive at the MAX station. Time elapsed: fourteen pulse-shattering, adrenaline-inducing, incredible minutes.
What's next?
We do it again--but this time, up the stakes.
They call it Hellway, but most people know it as Highway 26. Our route goes downhill right from the elevators, and there's no looking back: all eyes are focused on the road ahead. We drift around the Zoo parking lot, cross the freeway overpass, and make a left turn onto the on-ramp. We drop to a crouch, some riders hanging just inches above the frenetic spin of their back wheels, and pedal as hard as we can to get up to speed. The freeway drifts closer to the on-ramp, we fill the lane, and... merge! The freeway margins are host to deadly debris: gravel, glass, and metallic remnants of car accidents which will puncture your tires or convert your face to chiseled spam in the blink of an eye, so we take over the right lane at forty miles an hour.
Cars drift by in the leftmost lane: there's next to no-one on the road, but what drivers there are give us plenty of clearance. Despite the steep downward grade, I have to pedal as hard as I can to keep up: daredevils on minibikes draft in my massive air shadow, and then zoom past, tiny wheels whirring. After a couple of miles, we take the off-ramp, and power through the tunnel under the West Hills. It's an awe-inspiring sight: fifty-odd bikes flying beneath the harsh sodium lamps and arched tile walls. We burst out into the free air again, and, coming into the final stretch, coast under the soaring central span of the Vista Bridge. It's fantastic, awe-inspiring, like nothing I've ever done. When the train comes, ten minutes later, we're still grinning ear-to-ear.
Zoobomb: one heck of a bike ride.
Sensor Dust
The surprise beach trip with Andy last week was pretty darn fun, but it deposited some hefty chunks of dust onto my camera's sensor. So, now I have to get it cleaned somehow, and it looks like cleaning supplies could run me $150! Since I'm leaving in a few days, waiting for shipping really isn't feasible; I guess I'll have to get it cleaned some place in town.
