From a chain of emails
The subject of the Rotation came up & one emailer wrote -
"Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed." http://en.wikipedia.org/wiki/Rotation
And the reply came back -
Rotation, in the Maggie sense, is the semi-random orbital motion described by a constantly-changing number of suitors around a continuously-moving central point (aka, "Maggie"), interrupted by the occasional descent of one of the orbiting suitors to attend the central point on a temporary basis until drained and ejected back into the orbiting swarm to undergo rejuvenation/recuperation. Not unlike a cloth belt of 7.62mm in a Moebius strip configuration, passing sequentially from gun through reloading point and back.
Mmmmmm, I love it!
The two emailers may come out and identify themselves if they wish.
