bliumchikThe tiny Indian math teacher at our school usually takes us when Ms Vis is away. She had us a week or so ago, and tried to teach us about hyperbolas. What follows is broadly paraphrased.
Miss: Okay so infinity, right. See, you have to imagine there's this frog. Okay, I have this frog, and it does jobs for me, and then it comes to sit on my shoulder. But I don't like it sitting on my shoulder, because it's a frog. So I give it a job because it won't come and sit on my shoulder as long as it has work to do. Like you should not be talking until you have finished your maths work! Anyway, this frog, right. I give it a job that takes a long time, I trick it. I tell it, go jump to that wall, but you have to do it like this. These are the rules. You jump half the distance with each jump. So you see I am being clever, and he will never reach the wall because when he reaches halfway, *starts walking towards wall* are you following me, girls?
Class: O.o

Date: 2006-04-08 07:01 am (UTC)I'd be far more interested by the frog-and-wall version if the total distance travelled by the frog were constant - ie, if shorter distances hopped meant jumping higher to account for the rest of the distance of the jump.
And then introducing wind as a factor, moving the frog further toward the wall.no subject
