A blast from the past....non bee.

[beemandan]

I know, I know, this doesn’t have anything to do with bees. But while cleaning out a closet today I ran across this old friend from another time. Anyone else ever have to use one of these? Better yet...does anyone else know what it is?

icons ago? That some sort of inside joke?

[deknow]

I never had to use one...but I was fortunate to have learned machine shop practice with vernier calipers. If we keep this up, I'll have to post pics of my wire recorder: )

I was in the last class in my high school that learned how to use one of those- 1973 or 74, then our Scientific Calculations and Measurements class got TWO Texas Instruments TI-50 calculators. We thought we were pretty hot stuff...

I really like the old K&E engineering slide rules. I can't remember whether you add or subtract a power of 10 when the slide goes left..

It was never a directional thing, the way I learned. If you only had a short series of steps you kept track in your head. If you had a large number of manipulations you kept track on paper.

And three digits of accuracy! We put people into space with these things.

Makes my brain hurt just remembering........

Same here and I still have the slide rule but the Texas has packed it in yonks ago. We used to share one Texas between about 20 of us - I think the first one cost more then $ 300. Ten years later they gave a more powerful calculator away when you had two or more films developed...but that is another story!

There are enough of us old geezers on this site that we can surely 'one up' a young fellow like you on ancient stuff.

o-ooo
In Russia we called it "logarithmic scale". I have no idea how it's called in English. Yes, I spend a lot of time doing calculations with it. Sometime I missed old days (indicating that I am old), when life were simpler and one actually could disassemble and then assemble thing and it would work... In my "logarithmic scale" we also had a normal precise ruler - it was expected that one use it for technical drawings and "calculator" part is at hands if any quick calculations necessary. Sergey

I was able to learn beekeeping but not how to use a slide rule. More than a few buttons on a calculator is beyond me too. I have one in mycloset also, next to my dial phone, 8 track player, and reel to reel.

Slide rule. I have one or two - somewhere. -js

I had a circular slide rule in the 1970's and knew how to use it. I currently have a linear one like the one pictured above. Sometimes I threaten to teach the daughters how to use it.

I still have a circular one- built into a pocket protecter.

I still have my users manual, but have no idea where the slide rule is.

Waaait just a minute. I'm still using the dial phone in my extracting room. I have tried several others there but the ole ringer on the dial phone is the only one I can hear with all the equipment running. It's right over there on the wall by the 8 track tapes.
