Mesmerizing: Keepon Dancing Robot

Original image

Engadget turned up a fun story today about a little yellow robot who just can't stop dancing. The robot is named Keepon (pronounced "Key-pong" though I prefer to think of him as "Keepon Dancing") and is developed by Hideki Kozima (with dance-programming by Marek Michalowski). Looking a bit like two tennis balls plus eyes and a nose, Keepon is capable of dancing along to music. Because his two eyes are actually cameras (and his nose is a microphone), Keepon is able to interact with his environment, responding to stimuli. Here's Keepon in a new music video for Spoon's song "Don't You Evah":

For interested readers, there's more about Keepon at Wikipedia, more about the Infanoid Project (including other interesting, though not so cute, robots), a New Scientist article on Keepon, and a video of Keepon rocking out to a different Spoon song. Keepon will be appearing in LA this September in a benefit concert with Spoon. Any LA area readers interested in stealing Keepon and delivering him to my apartment/dance laboratory -- where he can be subjected to intensive dance research and repeated viewings of My Neighbor Totoro -- will have my eternal gratitude.

Belly Flop Physics 101: The Science Behind the Sting

Belly flops are the least-dignified—yet most painful—way of making a serious splash at the pool. Rarely do they result in serious physical injury, but if you’re wondering why an elegant swan dive feels better for your body than falling stomach-first into the water, you can learn the laws of physics that turn your soft torso a tender pink by watching the SciShow’s video below.

What's the Saltiest Water in the World?

Saltwater is common around the world—indeed, salty oceans cover more than two-thirds of the globe. Typical saltwater found in our oceans is about 3.5% salt by weight. But in some areas, we find naturally occurring saltwater that's far saltier. The saltiest water yet discovered is more than 12 times saltier than typical seawater.

Gaet’ale is a pond in Ethiopia which currently holds the record as the most saline water body on Earth. The water in that pond is 43.3% dissolved solids by weight—most of that being salt. This kind of water is called hypersaline for its extreme salt concentration.

In the video below, Professor Martyn Poliakoff explains this natural phenomenon—why it's so salty, how the temperature of the pond affects its salinity, and even why this particular saltwater has a yellow tint. Enjoy:

For the paper Poliakoff describes, check out this abstract.
