    The Three-body Problem
    From: Bob Goethe
    Date: 2021 Oct 24, 18:56 -0700

    I am reading an SF book now by a Chinese author, Liu Cixin, which has been translated into English:  The Three-Body Problem.  This led me to Wikipedia to see what the "three-body problem" was about.  It looked to me like a) the basic three-body problem that has intrigued people for some time has been the relative orbits of the sun, earth, and moon.  I had a little trouble following the article, but it seemed as though it might be a fundamentally unsolvable problem, influenced by factors we would describe as chaotic.

    Still we have all verified experimentally that the Nautical Almanc is enormously accurate.  On the other hand, it is generally difficult to get a copy of the Nautical Almanac for the next year more than just a few months in advance.

    I would appreciate anybody's musings about the three-body problem and whether or not it is navigationally significant.

    Thanks,

    Bob
