How do cats right themselves without over rotating? Or, as Destin, an engineer and the filmmaker behind the Smarter Every Day video series, rephrases the question: "How does a cat go from feet up to feet down in a falling reference frame without violating the conservation of angular momentum."
So as simple of a question as this is, it turns out to be a MAJOR POINT OF STUDY in Physics, Robotics, Space Satellite Control, Weapons Development, Biomedical Engineering, etc. It's stumped scientists and engineers since Newton's day....If you don't believe me that this involves some serious math... click here: http://count.ucsc.edu/~rmont/papers/cat.PDF
Destin assures us that no cats were harmed in the making of this video.
