Today I have absorbed a fact of fastidious importance, and epic value.
That walking and running limb movements are equal in things from ants to elephants. You have to find the difference in the square roots of the body mass of the animals and slow down time for the smaller animal according to that difference. At that speed, both elephants and ziggy and cruise at the same rate. It's all to do with the properties of a pendulum and the acceleration of gravity. A pendulum that is four times bigger than another pendulum, if you record them both and shrink them to the same size (video-wise) then the bigger pendulum will take twice as long to do a complete swing.

Thus, if you factor out size. animals swing their legs at the same speed, depending on how fast they are going. So a cheetah going at 50 kph will swing its legs as fast as an ant travelling at the same speed, factoring out body size..



Oh and, the running gaits of cats and horses are very different. When cats are airborne, they have their legs stretched out, and land on their front legs, whereas horses are airborne with their legs tucked beneath them, and land on their hindlegs......


Wow.. isn't physiology great?....


I was just sitting down wizzing through a noise control meter, the one in my brain, when it happened..... (please fill in for yourself, for your own entertainment).


Oh note to self:1-get counter up
2-get commenter up
3-post story + fill-in-blanks story.

Thankyou for your time......
