Davina Is A Geek Pt. 2

This time I'll begin with a picture, instead of ending with one.


I understand that now, in light of the picture, calling myself a geek has suddenly become pretentious. However, someone else showed me this thing and told me I was a geek, so I think it might be okay to say that. That was when I was telling her about my adventures on my robotics team.

Ah, yes. Robotics

A few months into the school year, I joined (at her invitation) a team that my friend Alix has been on for the past two or three years. I really didn't know exactly what I was getting into. At that point, I still held a pretty cliche mental image of robots as these clunky humanoid constructions of metal or as advanced artificial intelligence. So it was interesting to find out that the robot we were building was pretty much a box with things attached to it, and we were mostly designing its functions to be remote-controlled by, well, us. Also, we have very specific tasks that we need the robot to accomplish: collect raquet-balls from the ground in some way, sort between magnet-balls and regular ones, put them into crates, grasp and lift crates, rotate them, stack them--and, of course, good basic mobility is always important.
I spent much of my time just listening at first, which was already confusing to my thoroughly mechanically-illiterate brain.

Axle collars, nylon locking nuts, channels, bushings, long bolts and short bolts, threaded rods, servo motors...

Sorting all that out was just like BLUGHAGHH it'll take me the whole year just to figure out what everything means and how they work together so I'll never contribute to ideas for building the robot so why on earth did I sign up for this in the first place??

However, I'm getting there. I'm competent enough as a pair of working hands, at least, with enough experience now to know how to deal with the basic mechanics. I like to say that the scar on my knuckle is a battle scar, but it really is from when I accidentally scraped my hand across a gear while reaching for a hex key too hastily. Alix and I occasionally race to see who can get four bolts unattached from the steel channels first. I've beat her a few times.
We have lots of opportunities for these races, because we are constantly taking parts of the robot apart, tweaking them, and putting them together again.
It's like, we attach the mechanism to the robot, test, well that didn't work, what went wrong? let's try switching the gears around, detach the mechanism, do whatever, reattach. Test again.

It is so cool. You get to take the theoretical and make it real within a few hours--from an idea in the mind to a working prototype almost immediately. I'm learning a lot: problem-solving, teamwork, and new motor skills (heh), among other things. And when we actually get to drive the robot, it's like a video game in real life, which is just awesome.

So yeah, that's another way that I'm a geek. I create and fix really cool stuff, though that's not through much aptitude on my part. I just got the opportunity to be this kind of geek, and I took it.
If you ever get that opportunity, and you've got the time to spare, I advise you to take it.
It's definitely rewarding.

Davina Is A Geek

There is a picture at the bottom. If you don't feel like reading all this, you can just skip to the picture.

By geek, I mean language geek, to be more precise. Though I will admit that I have a distinct bias towards East Asian languages, since I'm most familiar with them after English.
I got so excited the other day when I was reading my Korean language book that I received for Christmas (see? I asked for that for Christmas = I am a language geek), and I could understand an entire written conversation without the use of translators. I suppose that would be rewarding for any student of any language, but this accomplishment was the product of countless hours poring over dubious sources on the internet, pasting words into multiple translators to see what they might really mean, attempting to translate song lyrics, documenting the uses of every single particle I discovered, and writing random Korean words over and over whenever I had pencil and paper to familiarize myself with the writing system.
So reading that conversation felt good. Really good.

One of the most discouraging things in the world is when you paste "dama" into Google Translate, and it comes out "dama."
I think I love and hate Google Translate at the same time. On one hand, the dictionary-ish thing that pops up for single words can be extremely helpful in figuring out various uses for them, and it's great for translating simple vocabulary terms that I just don't know--and for Chinese, the "read phonetically" function aids me tremendously, because it gives me the pinyin needed to type the characters. On the other hand, I will be frank: it's well known that the grammar is atrocious.  
"I like that cat better because it's prettier than other cats" in Chinese becomes "I prefer the cat, the cat because it is beautiful than the other."
Also, I don't know how much to trust the thing, period. I put "한치 (hanchi)" in once, trying to find out what it means after hearing it in a song, and I got "FLAMMABLE LIMIT". I don't think that was quite right.

I also have a love-hate relationship with my Mandarin Chinese course. Firstly, I love it simply because it's teaching me Chinese, and that is a language that I am totally ashamed to not already know. My parents are both fluent in Mandarin as well as a few other dialects. I feel like I should be, too. Most of my relatives speak Chinese. Some of them don't speak good English. I want to be able to talk to them.
One of the good things about the course is that it makes me write and read a lot, which is absolutely essential for any foreign language, but especially so for learning Chinese characters. Another good thing is that when we are given passages to read, my teacher never provides the pinyin (phonetic spelling of the characters, in case you didn't know) along with it. I know that other Chinese students can have problems with learning the actual characters when the pinyin is always included, because they end up just reading the alphabet they're familiar with in order to recognize words. I'm forced to memorize the characters themselves. No alphabet. Just words. MEMORIZE.
But then, my teacher also forgets to include pinyin when she's first teaching us new vocabulary. It took me a while to figure out that I had to just go to the course dictionary to find how to spell something. Before that, I just stared at the complicated characters, baffled as to how she expected us to just understand her sentences, grammar, sounds, new vocabulary, and all. Oh yeah, that's another thing. A lot of times she gives us long PowerPoint presentations to teach us new stuff, and there will be absolutely no translations inside. You have to figure everything out from prior knowledge and the pictures. Perhaps it's an attempt to simulate the way you'd learn through immersion. Just figure it out yourself.
I think that's a little similar to Rosetta Stone. Supposedly, you're going to "learn like a child." I wonder if that really works without actual immersion in a separate culture, where you'd be forced to use the new language all the time. Can you learn like a child while sitting at your computer and listening to one person's voice speak?
Maybe. I've survived through my course so far. All the same, I'd really like it if my teacher gave us translations.

If anyone asked me whether Korean or Chinese was harder--a question I think I've received at least once--I don't have a definitive answer. Both are really quite difficult for the native English speaker, but definitely not impossible for the dedicated student. Korean's writing system and phonetics are simple, a whole ton easier than the Chinese characters and tonal phonetics...but its complicated grammar structure and nearly inseparable connection to hierarchial Korean culture balance out any difficulty advantage that the alphabet provides. (Seriously, you use a different set of vocabulary and conjugate all your verbs differently depending on the societal status of the person you're speaking to.) Chinese grammar is a little more similar to English. IF YOU ARE CONSIDERING PICKING ONE OF THESE LANGUAGES TO LEARN, I RECOMMEND CHINESE, NOT BECAUSE IT IS MY HERITAGE AND I AM BIASED, BUT BECAUSE IT WILL PROBABLY SERVE MORE USEFUL IN YOUR FUTURE, AS CHINA IS A RISING WORLD POWER RIGHT NOW.  AND IF YOU WANT AN EASY LANGUAGE, JUST GO FOR A EUROPEAN ONE THAT IS RELATED TO ENGLISH. 

I haven't dabbled much in other languages. I took a little bit of Spanish when I was maybe ten, so I forget virtually all of that. I took an eight-week course in German once, but I forget most of that too. I tried learning Irish once. It's not as bad as Welsh, but the phonetics and spelling hardly made any sense to me, so I never really got past that. Japanese is one of those languages that I think I'll get to studying sometime in my future, but I'm not too interested at the moment. And Latin...eh. I learned that for a little while too. I will probably find my old books and go through them at some point soon, since I'm aiming to study biomedical stuffs, and it'll help.
Then, I'll learn Icelandic and Nahuatl and Aboriginal Australian. 'Cause I totally have the time. Pfft.

Oh wow. This is a pretty long post. I guess that suits the title.
