Étienne-Jules Marey was a French scientist and inventor who analyzed how things moved. He developed a way to photograph multiple stages of movement onto a single glass plate, a technique called chronophotography. Later, when Kodak introduced celluloid film, Marey swapped the glass plate for a roll of film that moved in between exposures. This technique formed the basis of cinematography, and it’s how he recorded the stages of a cat righting itself in midair. He published his findings in Nature and demonstrated how the cat splits its body in two and uses the inertia of its own body weight to spin around.

And buttered toast always lands buttered side up. If we put the cat and tape it to butter toast we can create infinite spin, so infinite power?!

ALL Cats Do Not land on their feet. My cat fall off the sofa all the time. Maybe the cat has to be at a certain height to land on it's feet.
