    I agree. Columbus was a genius of practical navigation
    but a very mediocre CelNavigator
    (at least by later standards).
    Pacific islanders were able to find tiny islands
    thousands miles away with very rudimentary CelNav
    no instruments and no "scientific knowledge" in
    our sense.
    
    In fact I think that all these fine points of CelNav
    have little bearing on practical navigation.
    
    And I also think that since approx 1980 Cel Nav has
    no practical value at all.
    
    Still some people, including myself,
    find some "intellectual fun" in analysing "performance"
    of Cook's expedition sextants and clocks and observers.
    The things which were perhaps of SOME (dubious) practical
    value 200 years ago.
    
    Alex.
