Just a tardy mention for your belated enjoyment:
I really sucked at chemistry as a kid. It was the math. Never could get my head around it. And as a result, after two tear-filled weeks in chemistry class, I gleefully transferred out to a benign and far more understandable earth-science class instead.
While I never mourned the loss much, every once in a while I'm reminded of just how shockingly much I don't know. The up side is that when I go poking around in various science-related sites, I'm like a little kid again, gasping with awe and wonder.
In hunting for a graphic for this site, I fell across this place. Not only does it provide some rudimentary explanations that I found, in some cases, fascinating, but it also has some dazzlingly wonderful graphics that are worth the visit alone.
So, for the geek that lurks below your surface, enjoy.
