Bernie B You said to Philip -- From Bernie Brauer Sat Nov 22 07:58:12 2008 If you go dwon to your local day-care centre ( where toddlers get dropped off so mummie can go to work to help daddy pay 66% ALL-TOTAL taxation ) you will see a toy where you can slide a wooden sphere along a circular thin metal rod. So the sphere is fixed upon the circular rod and the same point always shows inward. I have attached an illustration of what I think you have described but with the small addition of a straight, thin, light, paper tube attached to the wooden ball so as to indicate visually that it always points to the centre. The ball -- with the indicator -- is shown travelling around the circular rod in a clock-wise direction. Is this a fair representation? Please indicate any reservations or arguments you may have.
