I can barely deal with anything more complicated after dividing and percent, I think. (I last studied math at trade school like 15 years ago, in Europe)
I know, with it you can calculate everything, exept adition and substraction, this you must do still by hand. But it shows only the number value, not if it 13,48 or 1348. Later with the electronic calculators it was easier, more if they are programmable. Sadly when these appears I already finished my studies.
Electronic calculators have their own magic but with slide rules you conjure it yourself and it’s beautiful. I like seeing the how behind the why
Next time I visit I’ll ask to be shown again. I miss the long, boring explanations about how every single part of a keyboard works and how they all mechanically and electronically mesh to put our finger taps into words on a screen
I’m sorry for waxing nostalgia, it just kinda dawned on me I haven’t let him know I appreciated being taught those things because nowadays we just expect things to work and don’t question the “magic”
In essence is very easy to understand, you can eg. multiplicate adding to logarrithm numbers, as said too rulers with logarrithm scale serve to multiplicate two numbers, same as two rulers with a normal cm scale can serve to add two numbers, putting the zero of one on eg. 4,5 cm of the other ruler and youll see that under the 3 cm of the first ruler, appears 7,5 cm. so you have calculed 4,5 + 3=7,5. The slide rulers work the same way, only that they use different logarithmm scales, whith which you can multiplicate, calculate angles, square roots and other, depending on the used scale. Thr magic of logarrithms-
Imo, it is because those jobs are gatekept for specific kinds of people. It is not about the difficulty. In fact, the more education, the easier the jobs get because the lowest class is assigned all the hard manual labor like farming, cleaning, etc. The credentialist system is designed specificaly for inequality and exclusion
It’s just a different kind of difficulty, and of course not all jobs are created equal. But ultimately this rhetoric is the kind of thing the capitalists want. They want to pit “lower class” against “upper class”, when in reality, these distinctions are entirely irrelevant and it’s actually “the billionaire oligarchy squeezing every last drop out of the rest of us”. If you work for a living, you are “low class”.
Read “Caste: the origin of our discontents” and you’ll see that income stratification has always been about class, race, sex, and other arbitrary traits. There are “pink collar jobs” assigned only to women. I’ve witnessed anti-male discrimination in Direct Support & Nursing jobs for example and this is because that is not their “place” in the caste system. It’s not a rhetoric; it’s observation, evidence, and an accurate model of soceity

I finally realized the bottom of graduated cylinders is shaped like a graduation cap 🎓

I’m almost 60 years ago, using still this thing

Hey that’s really awesome! My dad showed me how to use one a long time ago. Those things are pure magic

Some graduated cylinders too

And this meme couldn’t even get it right
On earning my masters, my life really went to shit. Not that it wasn’t shit before. It just became shittier.
Why
Should’ve been an inanimate carbon rod.
Adventurous cylinder

Buddy should’ve used a manual drill 😎
Why aren’t there volume marks on the graduated cylinder? That’s what makes it graduated, not the bottom stand piece.
It’s on the right part, slightly darker gray
