Why Do Cats Always Land on Their Feet?


Ok, so the Internet is full of cat videos, but we rarely feature any here on Digital Diner.  Well, we recently came across this one that includes slow motion video AND some physics... so this is our kind of cat video!  If only they were all like this.
Have you ever wondered how it is that cats can always land on their feet?  Somehow in mid air, they can twist around and manage to orient their feet below them.  How do they do they make these turns while falling without some outside force giving them rotational momentum?  Watch the video and find out.

For the more technical amongst you, check out this paper on the subject.  Plenty of good math and physics in there.  Also check out the buttered cat paradox and why cats can survive falls from great heights.
