i definitely enjoyed reading this article, the topic caught my attention and no regrets stopping by. i had read articles on the cats unique landing ability in the past, really, its awe-inspiring.
i read an article about a cat that jumped from a height of about 500 feet and did not die, to think of it, the probability of a human surviving that is almost close to zero (cos, damn, thats about 32 floors high). I learnt this was owing to the fact that while descending, the cats is able to spread its legs out horizontally and relax its muscles, descending in a parachute fashion, also, its ability to land on all fours can as well be attributed to a gyroscopic reflex, just as you have clearly explained with the logic of angular momentum.
Gradually, my long lost love with physics is being rekindled.
