Jason Kottke has posted pretty cool videos that deal with animal physics. Enjoy them on your Friday.
First up is slow-motion video of cats falling. We see how cats land on their feet - rotating in mid-air while conserving angular momentum.
Next up is a look at the stability of an owl head. Kind of creepy.
Finally, chickens have a remarkable sense of their position in space. This allows their heads to remain still. Very creepy.
