My last question here was answered with such acumen, I shall try another... I am trying to flesh out an analogy to better explain the rapidly moving GP of the sun, but have no idea of how to do the math to portray it accurately. Let's say I suspend a pipe, 1cm inside diameter and 10m long, over the Earth at a point within the ecliptic. At the moment when the Sun's GP coincides with my "zenith-pipe", for how long a time will I see the light of the Sun making it all the way through the pipe? Of course, I guess I could just go to Home Depot and buy some half-inch pipe... Thanks for any takers! -Jeff __________________________________ Do you Yahoo!? Yahoo!
