    Re: Distance to the horizon in Bowditch and other sources

    Hello Robert,

    I, much like you, have come to appreciate the beauty (and applicatobility) of the concepts and mechanics of celestial navigation.  However, like many celnavers, I take mischevious delight in pointing out how we determine acceptable navigational positions on the basis of a fundamentally unacceptable cosmological view: geocentrism.  In a similar manner, I have come to appreciate the applicatability of flat-earthism.  Of course both views are incorrect; however, it seems that multiple cosmological views can productively co-exist depending on the problem at hand: a committed heliocentrist accepts the sun-centered view when discussing solar system mechanics but readily embraces geocentrism when using celestial methods to navigate an ocean passage and, the same individual, quickly morphs into a zealous flat-earther when levelling up the foundation for a new house.  May I suggest that you ask the flat-earthers you encounter to confirm their beliefs by building you a nicely levelled shed in the back yard.  The demand for those skilled with the tools of celestial navigation has declined in recent decades; however, with the severe housing shortages of recent times, those skilled with the tools of flat-earthism are in great demand.

    Cheers,

    Jim Wyse
