Thanks for the reply Mike O. Sure value your information.
I have just been confused because the back wheel of a riverboat
seems to rotate counter clock wise, where as the Paddle wheel of Homer Kelley seem to rotate clockwise.
Thanks again, Donn

Donn,
Per my prior post- It's really the principle of the paddlewheel- not any particular specifics that you want to focus on. Regarding your comment "the back wheel of a riverboat seems to rotate counter clock wise"- that would of course depend on what side of it that your on. If the wheel was pushing the boat forward then from one side the wheel would be rotating clockwise but if you went around to the other side of the boat it would be rotating counter clockwise.

Then from any particular side- whether it was moving clockwise or not, would depend on whether the boat was moving in forward gear or reverse gear.

Paddlewheel motion is a rotating motion of an entity (could be any entity) in a particular plane (could be any plane), for a particular period of time (could be any period of time).

Regarding Tong's question- "right forearm paddlewheel motion- what center Right Elbow or Left Shoulder?" The same applies- in regards to this discussion- it's not important what the center is- just so that there is a rotating motion- the center could be moving or changing but as long as the forearm was making an on-plane motion and rotating i.e. not moving in a straight line- then it would have paddlewheel motion. My term circle - implying a center - would probably have better stated as just - angular motion of the right forearm.

In summary, I still think that Mr. Kelley was really unclear(- what a surprise!) on this issue when you look at the different ways that he used it, throughout the book. I've touched on the principle of this concept- I guess if people need to chew on it more - then using or understanding specific examples in the book or asking questions regarding specific examples in the book would be the best way to identify and verify the principle.
