    I was being a little tonque in cheek in directing those concerned to Bell's
    theorem and quantum mechanics to explain the 3 polarizing lens phenomenon.
    Though it is interesting, it is a fair departure from the topic of celestial
    Agreed that the other analogies mentioned are more palatable but would only
    make the point that it is wise to keep in mind the limits of various
    theories. Pretending the earth is flat is pretty good in some situations,
    Newton's laws of motion work pretty good for the speed of most boats but you
    have to turn to relativity to set up satellites and make GPS work.
    Don't apologize, Jim, it lead to a fascinating trip through dimly understood
    ideas. To my mind, such pushing back of the frontiers of my own ignorance is
    a much valued feature that this List occasionally contributes.
