    Re: Sun goes round Earth, or something like that...

    Frank,
    The "fictional character" was Sherlock Holmes.
    Once I was walking in Warsaw with few mathematicians from various countries.
    (These were not students or simple PhD's but all serious research
    mathematicians, professors).
    As the only eastern European among them, I served as a guide.
    When we saw Copernicus monument, and I started to explain the history
    of the MONUMENT, one professor from China asked "who he is ?"....
    
    Actually the results of the poll you mention are not that shocking
    on my point of view. Is it really an important difference, what rotates
    about what? If you use the Nautical almanac every day, can you conclude
    from it that Earth rotates around Sun, not the other way around?
    
    Alex.
