"slip stick"

Hadn't thought of that term since my college days.

When you became a PE did you have a mini slide rule in your super cool pocket protector? Cripes I'm old...... ?????ÿ

@flga-2-2?ÿ

No.?ÿ I did not.?ÿ The one I used almost exclusively was plastic and about a foot long.?ÿ It came in very handy during tests as I could use an Eversharp to write key formulae on its surface to aid my memory.?ÿ Never got caught.?ÿ Had to be sure to always keep the finger tips on the edges or the writing would blur.

Wow! That comment is worthy of a National Enquirer headline. ?????ÿ

Can't believe Radar didn't use his classic "The Office" GIF saying:?ÿ "That's what she said."

Somewhere in the early 1970's there was an X-rated Swedish or German movie where the host of some party invites a beautiful young woman to go upstairs to check out his "slide rule".?ÿ He was a collector, as I recall, and had one that was extremely rare.?ÿ He explained that he was an "ingenieur".

I have several slide rules, the main one being my Post Versalog acquired in 1968.?ÿ The most unusual is a 2-foot long slide rule that my great uncle used.?ÿ He was a soil chemist.

I've seen one that had several segments of the scales placed on a rotary spindle so it looked like a giant corn cob, and was equivalent to a 30- or 40-foot slide rule. You had to figure out the approximate answer in order to know which of the high-precision scales to read, getting more digits than any other slide rule.

Edit: Much like this one:

As a grad student on the GI bill, in the 1950s, Dad had to buy a 2nd slide rule for home use so that no one would see him carrying one around. One for homework and one for the lab. He said the beatniks were out to mug all the professors so he had to adapt.

@flga-2-2?ÿ

Had to get the G. in there, didn't he?

Do you suppose it secretly stood for Gilligan?

I have my Dadƒ??s large K+E log-log sliderule. Iƒ??ve multiplied on it once or twice.

The machine Iƒ??d really like to have is a Marchand Figurematic mechanical calculator, 4 functions! Now weƒ??re cooking with gas!
