Why is "micro" (10^-6) abbreviated by the Greek letter mu ?
Obviously "m" was taken already by milli, so mu, the Greek
equivalent letter of the Roman "m", was chosen. :-)
But, but, but..... back when I became a ham (1952) in high
school and went on to engineering school the year after, in the
era of "cycles" (not c/sec), capacitor values (we were first
starting to get away from the term "condensers") were specified
in mmf (milli micro farads) instead of pico farads as done
today.
Inductance was always specified in Henrys, but that gave rise
to a lot of mirth because we had an Electronics teacher named
Henry who, when he was "having a good time" at our expense,
would boast that the "Henry" was named after him. :-)
