Right now, I'm thinking of a moment in my calculus-based physics class that I took last semester. Basically, the instructor is teaching us about vectors, the right-hand rule, and which direction the cross-product of two vectors is supposed to be pointing in. She assigns us homework, and I couldn't understand a word she was saying, basically. Everything was just too confusing. So I'm tasked to find out whether the cross-product of two vectors (a homework problem) is pointing in the negative or positive z-direction. I couldn't remember anything, so I just read the book and found that "the cross-product of two vectors will be perpendicular to both" or something like that. By all means, correct me if I am wrong. Anyway, I try to draw the vectors in the homework problem using a vector graph I'd printed out and figure out which direction would make the cross-product perpendicular to the two vectors. You can already tell that this was a terrible and unreliable method of determining the direction of the cross-product. I imagine that I got that problem wrong. Anyway, when she's re-lecturing us about those right-hand rules, and the vectors dictated by them, the instructor looks at the graphs I was attempting to write my solution on, and scowls at me. Right now, I can't help but worry about what she thinks of me; that I'm lazy and don't pay attention during class or even when she's trying to help me, because when I visited her in her office to inquire about this problem, she tells me to use the "right-hand rule" she described in class. I dismiss her explanations, saying that "I don't know how that works". She asks me why, and I just tell her that it's too hard. Right now, I can't help but feel shame for myself for wasting her time; and I'm worrying that she thinks of me as some lazy punk who doesn't want to work hard and listen. I feel like she hates me, even though I haven't seen her in many months... I'm not looking forward to the day that I will take her class again.(adsbygoogle = window.adsbygoogle || []).push({});
