    Motion of Geographical Position question
    From: FS
    Date: 2004 Dec 20, 08:16 -0800

    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
