[Elecraft] (OT) slide rules

[Ron D'Eau Claire]

Well, I still have my pristine K&E Log-Log Duplex Decitrig slide rule
that I carried in College. 

The Slide Rule also taught me the value of precision. Not the "nutso"
to-the-fifteenth-decimal-place precision we see so often now in the days
of DVMs with four decimal places or frequency counters that display to
the nearest cycle (excuse me..."Hertz"). Using a slide rule forced the
engineering student to develop a rather an intelligent real-world
ability to determine how much precision had any value in the situation
at hand, and to "round off" knowing what was important and what was not.


Uh, oh... that "soap box" slipped right under my feet, Hi! I'll put it
away.

BTW, I STILL don't know how to use some of the scales on that slide
rule...

Come to thing of it, there are a few mystery buttons on my TI calculator
sitting on the desk here....

Hey! Don't even ASK me about some of the more arcane commands available
on my K2.....
