    Re: Top fifty greatest breakthroughs since the wheel
    From: Alexandre Eremenko

    Frank,
    OK, by "sextant" I mean a "reflection instrument" in general, of course,
    and the date they gave is wrong.
    
    And they used a photo of a cheap modern reproduction,
    not a real instrument to illustrate it.
    (After having seen thousands of e-bay listings, I can tell even from
    such a small photo:-)
    
    Anyway, I think this was a great invention, the reflecting instrument,
    but certainly not in the category of "Top 50 inventions since
    the wheel".
    
    And I have other reservatons about this list as well (as probably everyone
    has). For example, such things as stirrup or composite bow
    probably had greater influence on history than nuclear weapons:-)
    
    Alex.
