    Re: On the Mischief of Geographical Position.
    From: Rodney Myrvaagnes
    Date: 2002 Jan 24, 11:18 AM

    This is rigorously true, but it dodges the question that I think people meant 
    to ask, vis: If the local vertical (gravitationally determined) doesn't point 
    to the center
    of the earth or the celestial sphere, then where is the position so measured?
    
    I can't read a sextant well enough on a small boat so the answer matters, and 
    I would be skeptical if anyone else claims he can. But that is the question, 
    isn't it?
