Last Thursday's physics lab was interesting.
It was supposed to be an "easy lab," which means that we should have only been there for, maybe, two hours max. Instead, Josh (my lab partner) and I ended up staying there for almost the whole three hours. I suppose part of it was just because we kept making mistakes and having to re-record data, but in any case, we were still figuring out what to write for our discussion when the last person left, which meant that the only people in the room were me, Josh, our TA (who will eventually be the subject of a whole 'nother blog), the TA from the other side of the room, and the TA from the next lab period, who usually comes in early. Us and three TAs.
The TA from the next lab period, who's this funny, loud, black dude, comes over and teases us. "You guys are still here??"
I hang my head in mock-shame and say, "Yeeaahh... we suck." And then, smiling: "Hey, as long as you're here, wanna help? We can't figure out this last part. Why does a square wave produce a graph like this?"
He comes over, studies the graph, and shakes his head, laughing. "I have no idea."
Josh and I, now that the silence has been broken, ask our TA (a soft-spoken Chinese grad student with a heavy accent) for help: "Do you know why?"
He comes over, studies the graph, and puzzles over it for a while.
I offer, "Well, the prelab gives a chapter number... Josh, do you have the book with you?"
He does, and we find the chapter. Our TA reads it, and then sets it down in front of us and says unhelpfully but apologetically, in broken English, "That explains it. Read it."
We read it, but it doesn't really help, and I bitch about it and say exasperatedly, "Okay, well, I guess I'm just going to write something random down," but then we start dicussing the problem aloud, and finally (tired of hearing our confused talk, I guess), the TA from the other side of the room, who's been on the computer, looks over and says authoritatively, "The capacitor is a spring, the inductor is a mass, and the resistor a damper."
It's silent for a moment, and then me, Josh, and the funny TA look at each other. I don't really get it, still.
Then the TA from the other side of the room speaks up again. "Think of it in terms of mechanics..."
And he goes on to explain it a little better and hey, it finally starts to make sense! And then the funny TA from the next lab period says, "Man, I never would have thought of that," and we all laugh, and he and the TA from the other side of the room talk a little and make physics jokes, and it's pretty cool to see them interacting like that. Our TA, who's standing a little way away, is listening too, and he even laughs quietly at some of the things that are said.
I find out that the funny TA's major is not physics, but chemistry, and I ask him, "What are you doing TAing physics?"
And he laughs and says, "Eh, I like hanging out with the physics majors. They're more fun."
I sort of botch my way through writing a discussion, because Josh still has to write up his copy of the lab report, but it doesn't really matter whether I wrote a good dicussion or not because it was just cool, what just happened. It's cool because it's been a long time since I've gotten individual attention like that, which is gratifying. But it's also cool because... well, because I had gone into physics lab kind of tired, and at first when we were still stuck in there at 5 o'clock, all I wanted to do was finish the lab and get out. But instead, I ended up being part of a nice conversation. Nothing big. But it was pleasant.
And I learned a little bit about physics, too, which is always good. :)
