Re: The Olympics

At 9:46 PM -0400 9/24/00, Justin Parke, you wrote about The Olympics:

It seems that the divers in the olympics (and the "trampoliners") are able to
execute half-twists, beginning and ending the twist in mid-air. I do not
know how they do this without violating conservation of angular momentum.
Could someone enlighten me?

Cats have been doing it 'forEVER'. (always landing on their feet)
It just took humans quite a while to figure it out.


It seems to ME that a stranded, motionless astronaut should be able
to do an 'about-face' maneuver in empty space, ending up motionless,
but facing 180 degrees from the original direction. (without
violating any basic principles!)
