The Limits Of Knowledge. Or science. Take your pick.
OK, so this could go in several places, but this is as good as any so I'll just leave this here
Slate article going over the basics of understanding and the very real prospect of knowledge without understanding. Given the views of many here on what counts as "science" I thought ppl might find it interesting. Bit disappointed they quote Popper with an implication of definitiveness, but that's the general state of "science" in popular culture, so not entirely inappropriate.
