Catching up on ATLAS work today, but while waiting for my Athena (software) to compile I'm catching up on some physics blogs. Bee, from Backreaction (whom I'll be guest-blogging for in the next week or so!) has linked to an older post of hers on "Water in Zero Gravity". Most people who've spoken to me in the last few years know that I've become mildly obsessed with fluid behaviors of all sorts, in the vain hope that I'll collect enough insight to better understand the "near perfect fluid" we think we're making at RHIC.
This one will haunt my dreams for a while. And this one (1930 animation, totally off-topic, downloadable here) will haunt yours (i.e. it's old, weird, fascinating -- and nominally children's entertainment. Go figure!)
