Interesting comments on slide rules. I had a couple, never was really good with them, years ago. Used to use Smoley's Tables for calculations, they were somethng. These days, a great deal of such calculations, possibly all of them can be done with the ubiquitous "scientific calculator" or "electronic slide-rule". I use an HP 11C, that I bought in the early 1990's, It had gone out of production, HP having declared it "obsolete", I don't know why, it's a great machine, fits easily in ones shirt pocket. As I recall, I paid between $25 and $30 for it.

I had thought that slide-rules were no longer produced, K & E gave up some time in the 1970's, correct me if I'm wrong. Is Pickett still in business, and what about Dietzgen, they also made slide rules. There are many, many buildings and bridges in use that were designed with the slide-rule, and they didn't need batteries either.
