'Unleashed'
[NAFDA] Spike-centric discussion. Lusty, lewd (only occasionally crude), risque (and frisque), bawdy (Oh, lawdy!), flirty ('cuz we're purty), raunchy talk inside. Caveat lector.
Word. I just had to Do Math for this job I applied for, teaching for Princeton Review for the GRE, and my brain just went "ARRGGHHH!"
I tried, I really did, but I had a 25 minutes time limit, and geometry? Algebra? PI and square roots, for fucks sake?! NO WAY.
If anyone could actually explain the number i to me in such a way that I could comprehend an actual practical application of it, I would swoon.
Yes, I said "the number i." Somehow, i is a number. I even know what it is -- the square root of -1. What I don't get is what it can be used for. Because it's NOT REAL!
beathen needs to change her tag, and also come visit me.
This has nothing with her being good at math.
Okay, maybe a little.
ETA: Well, crap, she has now changed her tag. Now to take care of the other part.
I think the number i was developed to torture young minds and scare us away from anything math related. I still like math despite this because that section of math class was blanked out in my brain for self-preservation.

Nope, it's imaginary. It does not, in fact, exist. But it helps you get from point A to point B sometimes. It's a mathematical wormhole.
I understand a, b, c, d and x...but i?
No, no.
Hey PC! I wasn't sure I'd catch you on here at the same time I was (but since I've been online all day, well, the chances were good).
I will definately come out for a visit. You only live, like, an hour and a half away!
Imaginary numbers are used in some things like modeling fluid dynamics, and some other physics things with looking at other things that move like waves or fluids. I can't really give a concrete example of how, though -- most of what I've been working on has been theoretical stuff, and I haven't looked at things like that much.

Nope, it's imaginary. It does not, in fact, exist.
But if it doesn't exist, then it isn't real!
....perhaps you see my sticking point with it.

Handwaving? But how can something that doesn't exist help with something that DOES exist???

Yay! We should hang out ALL THE TIME.
But how can something that doesn't exist help with something that doesn't exist???
No no. Something that doesn't exist helps with something that does exist. Inasmuch as negative numbers exist. Which, I suppose, they don't. But they don't exist on a whole nother level than imaginary numbers. Maybe you were right the first time.
