I have several slide rules. A couple of K&E's a Post and one

Thanks for your contribution, Jon. Now, just what was an
RPEE? That acronym misses even Wikipedia!

I still use a slide rule in my everyday computer work, Its a
Faber Castell Lecture theater model, and I have converted it
to work as a computer desk.
All the best

I am another slide rule fan. I learned to use one in
junior high school (what is now called "middle school" for
some reason). Learning to work with a slide rule requires
you to be able to make rough calculations in your head so
that you know the order of magnitude of the answer. I think
slide rules are still useful, for one thing they can give
you a continuum of solutions. I still have my first one, a
Frederick Post Mannheim style rule made of bamboo. My others
are more modern and more complicated. One is a log-log dual
base, the other a power log exponential, also dual base.
Both were made by Pickett. Pickett and K&E were the most
common but there were many makes. Collecting them seems to
be a popular hobby.
