Re: [metalshapers] Re: Slide Rule? What's a Slide Rule?
- When I went to MTU way too many years ago, I was required to take a non-credit course on the advanced use of the slide rule. Only a few students had or could afford a calculator so they were not permitted to use them as it was considered an unfair advantage. Computers still required punch cards. The slide rule was an amazing tool but it was so cold in upper Michigan that the temperature played hell with the accuracy of the tool. You needed to get in to the classroom early enough before a test for your slide rule to warm up or you would be getting incorrect answers. I have since forgotten how to use it. I considered getting it down from the attic the other day after reading some of these posts. I took a nap instead. Just as the TIG welder has replaced the oxy-acet torch for most of my welding projects, the PC has replaced the punch cards, slide rule and most calculators. I still know how to weld very well with a torch but the TIG has proven great advantages. I learned all of the usual engineering formulas in college. I don't use them everyday so I can't quote them but I know where to look them up and how to apply them. There is nothing wrong with embracing technology as long as we preserve the knowledge and accomplishments of our past. After all, isn't that the premise of the metalshaping groups?Rick

I can do just about anything I need to with a calculator,
but I did pick up a Slide Rule at a swap meet a few years ago.
I think it was $2,maybe less.
Honestly,I have NO idea how to use it,but at least I know
what it is,which is more than some people can say.
Some day when I'm bored,I'll learn how to use it.
> Ian, trhanks for posting the web site for slide rules. I justrecently purchased a slide rule on e-bay. I needed it to do ratio
and proportions when drawing the blue prints of my home additon and
updates. I don't have a clue how to do it with a calculator. I also
did not receive training on the slide rule when i was in school in
the 50's and early 60's. My introduction to them came when I
attended the Air force flight engineer school in 1968 then declined
reinlistment in 69. I searched every store in my area and could not
find one so I went to e-bay. So you don't need to be an engineer or
a scientist to own a slide rule, just to know how to do a couple
simple calculations works for me.

It never gets real cold in Seattle, but I do remember guys
complaining about their aluminum Pickett slide rules needing to warm
up so they'd slide easily.
