[Leica] noctilux factoid of the day

Good point......  Not so sure about the use of adding machines in
engineering circles......Persona;;y I never saw them used in that
environment, nor my Dad... who was a Civil Engineer starting in 1941.

I think that adding machines again were an accounting issue, not an
engineering issue..... but I am not sure

Of course there are and were tables.... books of logarithms ..... that were
used.  Calculating Square Roots using tables is quite trivial....

Have you guys never heard of Friden or Marchant desktop calculators?  These 
were way more accurate than my old K&E slide rule.  Friden even made one 
that calculated square roots.  All of the checkpoint calculations for our 
digital data reduction programs were done by hand by some talented ladies 
using these machines.
