[CIMC 2015 Part 3] Monsters and Pandas and Tigers, Oh My!

My inner perfectionist is crying that I have to post this, in particular over my pathetic snowclone title, but my inner pragmatist knows that, judging by my old blogging patterns, it’s now or never.

18.06: 56%, haven’t touched it in a while, but I think I can do lots more on the plane.


As a non-contestant, I confess I feel totally uninvested in the results and find the Closing Ceremony boring. All contestants go up, country by country, and have their awards read off. No effort is made to make any sort of buildup to a climax. But maybe this is for the best; we don’t want anybody feeling shafted or discouraged from continuing to do math due to a mere elementary-/middle-school competition. Meanwhile, though, I’m browsing reddit on my phone.

After this ceremony, the entire Taiwan delegation spends some time walking around outside while the guides make confused phone calls trying to decide where we eat lunch. My parents offer me some potato chips they bought somewhere, which are (as the label is really eager to point out) baked, not fried. Some time passes this way; eventually, the guides figure it out and we go through amazingly long queues to eat at the cafeteria, as usual. Then we are sent to a massive shopping mall for the afternoon, a place so large that its exits have number labels that go up into the double digits so that people don’t get lost.

(Nontopical life update: Current 18.06 homework status: 34% (mildly screwed, probably won’t finish before I leave my cozy home for the U.S. and I usually struggle to get into the mood for homework while traveling, but I guess I’ll have to)) [18.06 status panel: 34%] (I’ve been spending most of my uptime doing said homework and running errands, and my downtime catching up on Last Week Tonight with John Oliver while farming the Flight Rising Coliseum. And, okay, making the above status panel. Live version here courtesy of Dropbox’s Public folder. No regrets.)

Day 3 (Excursions)

Morning routine snipped. We come to the middle school again to eat breakfast and gather; the contestants will be taking their tests here (accompanied by one bottle of “Buff” energy drink each) while the rest of us will be going on an excursion. Before this happens, though, two Taiwanese contestants ask me and Hsin-Po some math problems. There’s a geometry problem, which I fail to solve:

(paraphrased) In triangle △ABC, ∠A is 40° and ∠B is 60°. The angle bisector of ∠A meets BC at D; E is on AB such that ∠ADE is 30°. Find ∠DEC.

Hsin-Po figures out that, once you guess (ROT13) gur bgure boivbhf privna vf nyfb na natyr ovfrpgbe naq gurl vagrefrpg ng gur vapragre, lbh pna cebir vg ol pbafgehpgvat gur vapragre naq fubjvat sebz gur tvira natyr gung gurl vaqrrq pbvapvqr.1 Then, there’s a combinatorics problem in a book with a solution that they’re not sure about:

[CIMC 2015 Part 1] Rainy Days in July (and Other Months)

We get up at 3:40 AM. By 4 AM we have left our house, speeding like a bullet into the dark.


(Ohai. Somehow it slipped my mind that I was ending my streak by leaving the country for a competition that would likely be highly bloggable, like my last two international olympiads, both of which led to notable post sequences on this blog. (Admittedly, the first one was never really completed…) My only excuse was that I was worried I might not be able to access my blog from inside the Great Firewall, but I did (via vpn.mit.edu) and even if I hadn’t, I could still have drafted posts locally in Markdown as I usually do, so I don’t know what I was thinking.)

(Also: because, as I’ve said way too many times recently, I need to do linear algebra homework, these posts aren’t going to be as complete or as perfect as I’d like them to be. Although I’m probably just saying this to persuade myself; I tend to include many of the boring parts as well as the interesting parts of the trip, which maybe benefits my future self at the expense of other readers. I probably need to get out of this habit more if I want to blog for a wider audience, though. Oh well.)

Backstory

The International Mathematics Competition (IMC) is, as it says, an international mathematics competition. But I should add that it is for elementary and middle-school students (in other words, I am not competing, okay??). (edit: Also, one or two letters are often prefixed to indicate the host country, for whatever reason. This year it would be CIMC, C for China.) I am tagging along because I am a student of Dr. Sun, one of the chief organizers, and have been slotted to give a talk and possibly help with grading the papers and translating. My father is coming to help arrange a side event, a domino puzzle game competition, which he programmed the system for; and my mom and sister are also coming to help with translation and other duties. Other people in our group: Dr. Sun himself, his longtime assistant slash fellow teacher Mr. Li (wow I’m sorry I forgot you while first writing this), my friend and fellow math student Hsin-Po, who is an expert at making polyhedra from origami or binder clips (and at Deemo); Chin-Ling, my father’s student/employee who also programmed lots of the domino puzzle server and possesses a professional camera; and, of course, all the elementary- and middle-school contestants, as well as most of their parents.

I don’t think I’ve ever given this amount of background exposition about any event I’ve attended to my not-so-imaginary audience before. It feels weird. Some part of me is worried about breaking these people’s privacy by posting this, which makes a little bit of sense but not enough for me to think that it’s actually a valid reason to avoid or procrastinate blogging. I think it’s a rationalization.

Here we go.

Day 1

The only interesting thing that happens at the airport is a short loud argument in the queues for luggage check-in, perhaps partly fueled by our high number of people and of heavy boxes (gifts for other countries and raw materials for Hsin-Po’s polyhedra). I don’t know whose fault it is.

In case I fail to scale the firewall, I attempt to download Facebook on my phone for one last look before boarding, but it fails during installation twice and I give up.

Our plane is not fancy enough to offer personal screens and entertainment centers for everybody, but thankfully the ride lasts only three hours, so this is tolerable. Instead, the plane plays the second Divergence movie on overhead screens, which I watch half-heartedly. The plot setup seems interesting but the ending seems to me to involve two Ass Pulls™, although since I haven’t been paying much attention I am not confident if I just missed some foreshadowing or character development. On the flight, I also read the proof of the irrationality of powers of e in Proofs from THE BOOK and leaf through the magazines.

I don’t hear any good music on-board, except maybe “Space Oddity”, which is a little freaky to be listening to while cruising at so may kilometers in the sky. Perhaps because of this, I find myself singing and humming “Space Oddity” unexpectedly often over the next few days.

Arrival

The very first sign we see after alighting the plane consists entirely of characters that are the same in Simplified and Traditional Chinese — if I remember correctly, 「前有坡道,小心慢走」1. The Changchun airport looks like any other airport, coolly blue-themed with moving platforms. The restrooms have fancy bright purple soap. Even though I consciously think about how I have suddenly arrived in a country that places notable restrictions on freedom of speech and Internet access, I don’t feel it. Eep, what an anticlimax.

Translation Party

Just a short anecdote for the streak today. Hmm, I guess this developed beyond being just another filler post, which is good.

In addition to preparing my presentation, the other job I have to do for the math competition I’m attending in a week or so (not as a participant, okay?) is translating various guests’ speeches between English and Chinese.

The speeches’ length and formulaicness really get on my nerves, but then again my standards for speeches were skewed upward by Richard Forster’s speeches during the opening and closing ceremony of IOI 2014, but on the gripping hand I don’t think it’s that hard to at least try not to be formulaic and I really can’t see any effort on their part whatsoever. Off the top of my head, pretty much all the speeches tend to go like this:

  1. Welcome!
  2. Math is great!
  3. This competition is great!
  4. The city hosting this competition is great!
  5. The college hosting this competition is great!
  6. You contestants are great!
  7. Good luck!

Except each bullet point is a paragraph that lasts a minute.

(Ninja edit: Which is not to say they didn’t put any effort into their speeches at all, but that much of the effort seem misguided to me. I don’t see how anybody who has been in the audience for one of these speeches can overlook the same flaws in their own. Unless it’s like, at some point in the natural life cycle of the human brain, people spontaneously start enjoying these safe and repetitive speech topics instead of some earnest and maybe lighthearted advice and anecdotes and jokes? Like how people somehow start enjoying spicy stuff, or the bitter flavor of beer and wine, or writing teenage-angsty ranty posts complaining to nobody in particular like this one? Tough questions.)

Anyway. My mom actually does most of the translation but I am the grammar stickler post-processor and we work together on the hard parts. The second hardest things to translate are idioms. The hardest things to translate are quotes. It turns out that lots of people find translated quotes to Chinese and it can be incredibly difficult to reconstruct their English versions. Here is the quote that today’s story is about, which we were tasked with providing the English translation (or original) for and which the speech attributed to 克莱因 (trad.: 克萊因).

Phone

tl;dr: anybody want to add me on Line or tell/remind me about other phone chat apps? betaveros as always.

Wow, talk about uninspired post titles.

I got a new phone today. Or, well, it’s second-hand, actually. I try to make electronics last a long time, but I think this was justified given the state of my last phone’s screen:

old phone screen, with a visibly malfunctioning black patch

Besides, I’m going off to college and all. Anyway, the phone is pretty cool. It’s a slick shade of red, it came with a cover and everything, and it has one of those fancy 3x3-grid locks. How secure are those again?

Well, we could just find the answer on StackOverflow, but that’s boring.

Last Step

It is more than slightly intimidating to go into the room through the big sliding door and see everybody dressed up in full-on green surgical garb with masks and hair nets. I don’t remember this part. Feeling a little vulnerable, I change my clothes.

I ask to listen to my iPod during the operation — I remember being able to do this during the operation four long years ago when the subject of today’s surgery was inserted into my shoulder — but the nurse(?) says it’s best not to do that because they’ll be using something electric to stop the blood. Instead I can listen to music played from a computer in the operating room. Well, okay then.

She escorts me through a bunch of twisty little passages to said room. The computer is a dual-screen Windows XP. The nurse shows me that there is a folder with random albums sorted by year. I poke through the folders and create a playlist in Windows Media Player interleaving 1989 with a collection of classics from 五月天(Mayday). Then I get on the operating table and wait. One of the nurses compliments me on my choice of the latter band. A few tracks later, I deduce that my interleaving had been to no avail because the media player was set to shuffle. I spend a lot of time on the operating table at first not doing anything except stare at the ceiling. There is a white three-legged contraption there, with each hinged limb ending in a large blue-rimmed circle of surgical lights. There are white sans-serif letters inscribed on the rims, saying Chromophare® E 668 and Berch-something. I think the “something” was a synonym for “say” or “tell”. An after-the-fact search says it’s Berchtold. Typical human memory.

Later I am covered with lots of green cloth, which blocks out the ceiling. Instead, I can only see a clipboard and random paper forms on the left side of my peripheral vision, presumably propping up the cloth. The clipboard is a highly translucent pink. The form on top is yellow and has a box saying something about somebody paying; the form on bottom is white with a black-and-pink-striped right border. The clipboard’s clip also has random streaks of black marker across a white sticker.

Music plays.

Scary Cars

(Part of a daily posting streak but for once I don’t think I need to apply the disclaimers to this. If you thought for even one second that the title was a palindrome, I’ve succeeded. It’s not. I don’t have a good title. Okay, maybe slap the disclaimers onto that part.)

The first time I drove a car was on 5/18. I think. I might be off by a day or so. Most of that day’s lesson was spent learning to go forward and backward, accelerate and decelerate smoothly, and turn the wheel without getting my hands tangled up. My coach made me count out loud how many circles I was turning: 一圈半圈半圈一圈etc. It felt kind of stupid when I was doing it, but I guess in the end it helped, and eventually once I got the hang of turning the wheel, I just subvocalized it and my coach also tacitly stopped bothering me about it.

The first time I activated a turn signal light was probably on 5/26. That was the day I wrote in my TIL log that, when you turn the steering wheel back from the direction you were turning, the turn signal lights turn off automatically. After you think about it, this is a pretty sensible thing for turn signal lights to do, but when I first learned this my mind was utterly blown. Wow!

It’s like when you’re turning and you turn on the turn signal and it starts clicking this steady beat to increase the dramatic tension, like you’re doing a trick in a sports driving game and you have to quickly hit the right sequence of buttons on the controller. Then you actually turn the corner and then turn the wheel back, and as the wheel makes its smooth sliding sound back to its upright position, the beat stops like a resounding V7 to I resolution, as if to congratulate you on executing a beautiful turn without crashing into another car or driving off the side of the road.

That’s what it feels like, anyway.

On slow days, when you’re halfway through a turn but the drivers ahead of you are waiting in a queue that stretches on forever on the practice track, you can shift to the parking gear and use the turn signal’s beat as a metronome and sing along to it too. I do.

Or, of course, there’s the obligatory xkcd:

8 Songs for 18 Years

At some point I thought, hmm, maybe this blog would benefit from some more sentimental, memory-capturing music/videos, like I chose for my end of 2013 post or my end of 2014 post. (Yeah, I link to my own posts alarmingly often. I think that’s kind of weird. I don’t know.)

Obviously, because you’re reading this already, I decided to follow through with that idea. There’s no particular significance for posting this now — it’s not my birthday or anything, as the title might suggest; it just has a nice ring to it — except of course that I’m starting to get mildly desperate for content for my daily posting streak exercise. Standard disclaimers apply.

This is mostly for my future self. I should note that, although I like these songs, this is not a list of my absolute most favorite songs ever. You can tell because there isn’t any Coldplay or fun. (the band.) Instead, each of these songs was chosen to be meaningful to myself and my life in at least two different ways that generally don’t overlap with the other songs. This was difficult but I think I managed it — you know, how constraint breeds creativity and everything? Also, they’re arranged by approximate chronological order of impact. But it also means that this list isn’t going to be that meaningful to anybody other than myself.

Also, I have a long list of class-of-2015 sentimental songs, which I’m not including here because I think there are so many that they deserve a separate post. Will I avoid procrastinating and feeling awkward for long enough to make such a post? Stay tuned!

shrugs Whatever, enjoy the music or stop reading now if you want.
