Auction find

[Tony in SD]

My high school algebra teacher taught us how to use one. It got me through college, pre handheld calculators. I believe individuals trained on slide rules are better at estimating results. I have my ex-bosses' slide rule, he was a double E so it has a log-log scale.

Mine has log log scale too. I too am a BSEE

Yes, I have one, not sure what brand, yellow bi metal, showed the kids how to use it.

When I was in high school and my first couple of years in college, the holy grail of slide rules was considered to be the Keuffel + Esser Log-log Deci-Trig.

I didn't care for straight slide rules, and used a circular slide rule that fit in my shirt pocket. It was in essence a stamped aluminum disc with printed scales, having two radial-line cursors on one side and a single radial-line cursor on the flip side.

Interestingly, that particular slide rule was made by a little-known maker that sold some under the maker's name, and sold many more by branding them for others to sell. Mine is branded Post, and I've seen the branded Dietzgen.

When the internets are down and the batteries in calculator flat and it’s raining (so backup solar powered calc is also dead) then this comes into play . . . providing I can find a magnifying glass!
The tip of the cursor is broken but it is still quite usable - and the slide-out is double sided and loaded with amazing (useful?) info, equations, conversions.
An estate sale find that I didn't want consigned to the trash.

Still have my K+E from engineering. Got me through the first year of college ('73/'74). then supplemented with a 4-function calculator. Got an SR-51A by my junior year. Would need some review before I could use it now!

I also have a K&E, a Precision plastic, and a basswood/brass. I had to dig them out and couldn't find my round one (too easy to hide), but I did find my first electronic version. Amazingly, it still functions with a fresh 9V in it.

I can still do up to cubes on the K scale, but would have to review before flipping over the slide scale and doing any real math.

I have my old standard Post brand and a small pocket slide rule (6") made by Sterling that I carried in my pocket protector with the leaky ink pens. Today I don't have a clue how to use either.
Much later bought a solar Scientific calculator, thought it was the cats pajamas.

Reading your post promted me to go pull mine out of my desk drawer. It is a K&E from the mid sixties.

I still have my K&E Deci-Lon in the case, both it pristine condition. Bought one of the first Texas Instruments Scientific Calculators and used it until HP had a better unit.....that put the Deci-Lon on the shelf. Sure made the job easier........but having to calculate where the decimal point goes with the K&E kept the mind exercised which I always felt....keeps it sharp...your mind!

Last used one my senior year in HS, a l o n g time ago. 66 years! And, no I don't remember how to work one.

I have one somewhere, probably with my drawing board, triangles etc.

My Dad taught advanced math so he of course knew how to use one.. Tried to teach me but was only moderately successful and what I did know 60 years ago has mostly left me. Dad's Pickett is around here somewhere tucked away,, probably in the same box with the rotary dial telephones, LOL

I remember the telephones before rotary dial. You picked up the ear piece and listened for the operator, then spoked into it and told her the number you wanted to call.

Or you picked up the phone and listened to your neighbors whole conversation!

Way above my pay grade. The calculations that I need are available through the functions of my brain, or a calculator.
