Now, this is not very interesting.

Sherlock Holmes doesn't know how many planets are in our solar system, but he knows the minute difference between different cigarette ashes. Hmm.
And he's famous for his deductive reasoning, and most of us are not. Now, he's also fictional, but that is beside the point.
College (and school before college) teaches some very useless information. Or, at least information that will become so completely unuseful after college that it seems kind of... irresponsible to crowd our brains with it.
(Because yeah, we can store as many bits of knowledge as we want, I'm not arguing for limited memory storage but recall DOES get harder. That's about as fact-y as psych gets...)
I guess what I mean by all that babble is:
Scientific Calculator v Graphing Calculator v Calculator you get as a free gift from some finance based business. I know difference! I didn't think that was weird. But after going home and requesting to know where in the hell my scientific calculator had been stored and being met with blank stares and then three (yes, three) graphing calculators, I'm beginning to realize that it's not really standard. Standard knowledge, I mean.
And why would it be for a non-math profession? (And why on earth would one turn down a graphing calculator in favor of one that doesn't do as much? Precalculus tests- Also, why would someone spend a quarter on something when they could just plug it into their big shiny machine...)
So I think I'm going to try to forget it. Because this is not something that I need to know.

EDIT:: 4/28/09 "Also, why would someone spend a quarter on something when they could just plug it into their big shiny machine..." I just read that again. It didn't make any sense. At all.

Conclusion: I appear to have meant "Who would someone waste a quarter in college (10 weeks) on a class to teach them something that can be done by a calculator." Which does make sense.
