Dennis and the group,

I learned the thorough use of the slide rule as part of an year long 
extensive training in Nuclear Reactor Operations and Maintenance.

I pull out my "paint stirrer" several times a year.  I find it 
refreshing to do this, AND watch the looks of those whom have grown up 
with nothing BUT calculators.  Most of THOSE are locked into the 
formulas being built into the calculator.  They simply plug in the 
figures for the variables.  Unfortunately I find that "they" do NOT know 
what the variables REALLY are.

I have K&E AND Picketts.  All are Deci-Logs.

I "may" be getting OLD, but, I try and keep mentally sharp.  Hence my 
discussion on another list regarding the "purported" complete 
interchangeability of E for V, and A for I.  There are specific 
reference materials that list the use of these terms AND what they 
"actually" refer to.

Those that fail to hold to "defined" standards, make errors in their 
results.
