    George,
    
    
    Excellent article indeed by Doefler !
    
    Congratulations to its writer, and thank you George for mentioning it to our NavList Community.
    
    
    Antoine M. "Kermit" *** Couette ***
    
    
    *** Couette ***: by the way, same family as Maurice Couette, who worked on 
    hydraulics (just google "couette flow"). He investigated a field under 
    intensive research to-day ( e.g. 
    http://documents.irevues.inist.fr/bitstream/handle/2042/16374/CFM2007-0040.pdf?sequence=1).
    
    Some of his research on fluids viscosity have (unexpectedly) been further 
    studied in order to reduce cavitation around ship propellers (... back to 
    Navigation at last !!!)
    
    He is (was) my great grandfather.
    
    One of his sons - my grand-father - married Marie Sperry, a lady closely 
    related to Elmer Ambrose Sperry, well known inventor of a gyroscopic compass, 
    which eliminated variations caused by the Earth's natural magnetism (back 
    again to our current topic !!!)
    
    That's a small world !
    
    
    :-))
