[Boatanchors] correcting a misreading of an earlier mail

   To Bob, N0DGN:  If you read my original text carefully you will see that 
I in
   fact equate "Siemen" (actually "siemens") with "mho," an ohm standing on 
its head" i.e.
   upside down omega. (reciprical of ohm , 1/ohm)
   My ironical question was whether, from a logical point of view, seimens
   spelled backwards, "snemies" would then again be equivalent to an ohm!
   I could have laid it on even thicker by asking if a "snemies" should be
   represented by an upside-down S, an S standing on its head.

  BTW citing my ancient Referernce Data for Radio Engineers, 5th editon, 
page 3-6:
        "siemens  S  Depreceated. Use mho."
    [Note: Here, units are not capitalized, regardless of whether or not
    they may be named after individuals,
    e.g. siemens, ohm, henry]

  Also, in another reference book, I found G used to represent conductivity 
and
  is defined as:
         "1/R   unit 1/omega ;  1/omega = 1 mho"


  I had NOT checked to see what the most up-to-date conventions are for
  representing conductivty. Actually I have now, on the internet, but that's
  another story. It appears that there are also other symbols for electrical
  conductivity.
  Keep in mind that my original post was meant to be humorous
  and not a stringent, scientific/academic presentation.

  For some, if not most on this reflector, much of what I've cited
  is kindergarten stuff, but sometimes it doesn't hurt to refresh
  on fundamentals.

  All of this is going off on a tangent, considering that we started
  discussing designation and abbreviation conventions applied
  when Boat Anchors were produced. (Not that I'm not one of the
  culprits involved!)
