Was going to post this on Facebook (had already posted it on Twitter), but realized that this is the kind of stuff I used to bring here. Back in the old days.
Anyway: I ran across this (via Twitter) this morning and want to make sure as many people as possible see it. The content is delightful and informative.
BUT: the Big Important Point is one that I've hammered at for a long time, and the one that drives all my work: It's a perfect, and I do mean perfect, example of how academics, experts, intellectuals of all kinds (scientists, anthropologists, historians, whatever) can use new media to communicate complex ideas to a wide audience.
