I came across this tool in my storage just the other day. I have not used it for about 30 years. It has 3 parts, no batteries and it put men on the moon.

Do you know how to use one?

Its a slide rule if I’m not mistaken? My dad showed me one when I was a teenager, he used it in the merchant marine academy in Sweden to calculate things for the engine timings and other such. An old time calculator. I’ve never used one

Yes it is. I have use one for many years, just not recently. I am going to use it more since I found it. It can multiply and divide , but can not add and subtract worth a damb.

I still use one from time to time in the shop. Especially when my feeble mind seizes up on me and I can’t figure the next closest fraction under or over the one I want.

Slide rule it is. My brother was an engineer, before he passed away. I was a youngster and I remember him coming home from college (Clarkson College, now Clarkson U I believe) and showing me, or trying to show me, how it worked.

Bert – My father had an Abacus, and he knew how to use it. Old school, pretty cool. I have no idea what ever happened to it.

Yes a slide rule! They even made circular versions used extensively by pilots of aircraft in flight planning and windage calculations. They are based on additions of logarithms for multiplication.

Yes, a slide rule it is.
Isn’t it for one to place in there pocket, along with a pocket protector….
To make them look like a nerd??? :^)

I was never taught how to use a slide rule, though I believe it should have been mandatory. Calculators were new, when I was learning geometry, algebra, calculus and the like. However, we were NOT permitted to use them. We had to do all the math ourselves!!!

Were the world to run out of electricity & batteries….
I don’t believe most people could figure out 2 + 2 = 4, successfully!!!

The pearl or shiny plastic laminated bamboo Picket & Eckell’s were considered the ultimate rulls to stay accurate during temperature and climate changes. Were approx. $ 100.00 in the late 1950’s.

”They even made circular versions”

Circular wheels were also used to calculate reproduction sizes for photographers and graphic artists.

I have my dads Slide rule – but never played with it much -
Like everything – there is a youtube video how to use one.

Though the videomaker needs a little less Caffeine.

Do have my EB6 from my pilot bag doing wind and heading.

I had one in high school, but quickly gave it up when they invented electronic calculators.

Yes, I do know how to use one. I have a Pickett Log/Log Duplex. I drag it out every now and then and use it or at least try. I need to refer back to the books every now and then. Obtaining the accuracy that is so readily available with today’s calculators is the real short coming. Well, maybe by vision is rapidly becoming the real limiting factor.

I used to be pretty efficient w/ a slide rule. I doubt I could figure it out now. I for one was very excited when the calculator came along, and I embraced that technology wholeheartedly.
