Real Life Adventures by Gary Wise and Lance Aldrich for February 26, 2023

He has how it works down pat.

I finally threw mine out about 15 years ago.

Logs and log-logs. After that, I got a hernia.

That’s about all I remember. Hated trying to use it.

We sell LOG.

Back in 1975, my college had a contest to see who was the fastest with their calculators. The contest was to multiply and divide a series of numbers. I insisted on entering with my slide rule and they eventually let me. Everyone else either had an HP-35 or SR-10. I won.

That looks like a Pickett.

Never learned how to use a slide-rule. This was the mid-70s. Of course, I avoided like the plague anything that might require such a torture device.

The answer is there if only you know where to look!

I still have mine and pull it out ever now and then to fiddle with it but most of its gone. If life slows down I’ll pull out the instructions so I can do tricks to impress people.

I still have the small one I got from my grandpa. I also have the larger circular one I actually used for school, as it was compact to carry and I bet there aren’t too many of them around any more.

He might want to calculate how far off the cartoonists are on his age.

We were taught how to use them back in my HS Chemistry class in ‘71/’72. I have, of course, pretty much forgotten it all.

I have my grandfather’s slide rule from college, with a leather case autographed by his friends – class of ’23!

My father never got around to teaching me how to use his slide rule. My mother made me give it away, along with his geometry set.

It’s good for reaching things you drop just out of your reach…

Slide to divide, move the hairline to multiply

Easy peasy. But not as easy as a battery powered calculator.

I had to learn how to use a slide rule for the Navy’s Nuclear Power School back in ’75. I promptly forgot it.

Still got mine! Last used about 1972 in an Applied Engineering class at PSU in Portland, OR

I used it in high school in the 70”s. Not well. I’d have to warm up to establish which lines were needed with a basic equation I knew. Calculators had recently come out but the board decided they were too expensive to be a fair purchase for students.

Still have my holstered and my mini

I would play around with my Dad’s while riding around in the car in Huntsville AL 1965. They put a man on the moon with those things.

I worked at HP drilling holes in printed circuit boards for HP35 and HP80

We put men on the moon and brought them back with slide rules.
