This has nothing to do with anything, but I saw a few optical illusions today and had to share them.

Rolling circles
Whirling seeds
Spinning snakes

Are they moving? Look closer…

I love that a black hole can be heard singing! Or maybe it’s meditating, doing one long Om.

Hiya,

I’m working on a lecture about human language and its relationship to abstract thought and culture, and I wanted stuff on meerkat alarm calls for comparison’s sake. I stumbled across this great site talking about animal behavior and communication in a number of arenas, all assembled for your reading pleasure. It has the overly simple title of “biology – animal behavior”.

It’s true! A newly discovered carnivorous dinosaur from India has been named the “Rajasaurus”. It’s fun…

I’ve been reading a lot about carbon nanotubes lately. (Specifically, I’m reading The Space Elevator, which is fascinating despite the sketchy writing style.) There seems to be no end to great uses for them, including bulletproof T-shirt fabric. And to think, we didn’t even know they existed until a decade ago. Go nanotubes!

UPDATE: Deb noticed that I had the wrong link. It’s been corrected.
