The evils of chemistry...

Just spent eight hours doing chemistry homework. The first five problems were pretty easy, with conversions and use of the speed of light and Planck's constants ... and then I stepped into quantum mechanics. Why, chemistry, WHHHHHYYYYYY??!?! *weeps*

So I spent eight hours doing seven chemistry problems. Seven. And then, going back through to correct my stuff, I find out that I continuously lose track of a stupid little square symbol that throws off every other part of my equations. *throws pencils around in a fit*

To top things off, we don't even officially cover quantum mechanics until tomorrow. *looks at stack of paper used to do problems* I think I killed at least a tree today.
