they rule

Pretty useful, I can't wait for my battery powered one to come in.

I have one but IDK how to use it, someone just gave it to me one day.

Is worth learning?

>>8397058
It's easy to learn how to use them and there's tutorials all over the internet. It's pretty fun once you get the hang of it.

In the 1950's, futuristic pirates were thought to look like this

Pen, paper, slide rule: the practical minimum.

>>8397252
Its also cool as fuck

>>8397030
They also slide

Why not just use a calculator?

>>8397348
Slide rules are faster if you know how to use them.

neat

I suppose it will be useful after the apocalypse when the lights go out

>>8397013
cool, but you still won't find a gf

>>8397344
No, it's not.

>>8397252
they designed and built the SR-71 with those tools

Fucking awesome. Too bad I left my dad's out to be chewed up by my dog.

Like abaci and manipulating equations on paper, slide rules give you an incremental path toward doing it in your head, which calculators don't.

If you use a slide rule enough, you also develop a visual/tactile memory of its workings. You're constantly looking at the fixed scales and lining them up in your hands. Over time, you'll effortlessly anticipate what the slide rule will say, and use it only for increased precision above your instant awareness of the approximate answer.

This is a tremendous benefit to rapid estimates, and is probably a signficant contributor to the seemingly prodigious feats of mental calculation common among scientists and engineers of the early-mid 20th century.

Thank god i was broke and did not buy one. Thank god i've grown up since then.

Smart anon is smart

>>8397013

I think that I would like to learn how to use mine, but I haven't gotten serious about it yet.

>tfw have a soroban, slide rule & a nice compass kit

Apparently the engineers at my Uni used to have a meme of carrying their slide rules like swords, giving them names, being knighted with them, etc.

>>8398878
That's a really fun "meme" Anon

>>8398878
I really, really like this meme. Do you mind if I save it?

>>8398899
Those are really fun "dubs" Anon

>>8398944
Y-You too

Damn, and I thought the iron ring thing was cringey

>>8398964
What's cringey about the Iron Ring?

>>8399055
Canada

the oath:
>…I will henceforth, not suffer or pass, or be privy to the passing of, Bad Workmanship or Faulty Material in aught that concerns my works before mankind as an Engineer, or in my dealings with my own Soul before my Maker.

>>8399237
It's from the 1920s. It would be more cringy if it were changed.

>>8399247
nope, times have changed and oaths should change with them. traditions for the sake of tradition are stagnatory.

>>8399247
Not to mention that it was written by Rudyard Kipling

>>8399249
Why not tradition for the sake of bringing together different generations to impress new graduates with the seriousness of their work?

>>8399055
Wearing jewelry on your pinky finger doesn't make you an engineer, it makes you faggot
>inb4 what's the difference

>>8399247
letme suggest a new oath for the Atheist-fags in the thread:
>... I will henceforth, not suffer or pass, or be privy to the passing of, bad workmanship or faulty material in aught that concerns my works before mankind as an engineer, or my dealings with definitely nothing spiritual, my lord Charles Dawkins, and the void.

now you can stop complaining. and be irresponsible engineers because you have no god and no moral obligation.

>>8399249
traditions can be good. The oath does not have to be taken in the context of theism, but it is still important. the oath makes you promise that your entire being will be dedicated to ensuring that you place the lives and safety of others in your works before the wealth to be obtained. The Rings are made from a collapsed bridge that killed hundreds of thousands of people because the engineers were no obligated to follow any descent moral code. Because the engineers were not obliged, they were able to produce and buy cheap materials that made the bridge kind-of-sort-of safe to cross. It is a reminder to engineers of their civil duty, and lets those who put morals in second place that their status as an engineer can be removed, just like the ring.

Consider this.

>Many incorrectly believe that the rings are made from the steel of a beam from the first Quebec Bridge, which collapsed during construction in 1907.

With this in mind, can they at least start using titanium or inconel or something? Who the hell still does serious engineering work with wrought iron.
>inb4 civil
Serious engineering work.

>With this in mind, can they at least start using titanium or inconel or something? Who the hell still does serious engineering work with wrought iron.
Only Toronto still has rings made of iron, IIRC, and they're optional. All other rings nowadays are made of stainless steel.

>>8397013
It's outdated technology. No point in using one over a computer. I guess you can learn to use one for the case of a blackout if it makes sense for your job.

>>8401580
Thanks, I don't think anyone in this thread realized they might be obsolete.

>you will never be a scientist or engineer in those times
>you will never use a slide rule for everything, developing god tier mental calculation skills just as a side effect of doing normal work
>if you use a slide rule today instead of a calculator you will regarded a a retarded hipster
>you will never be as good at basic mental arithmetic as your professors unless you actually make an effort to practice

>>8397013
Set the times back and test what you can do without a PC, a calculator or such stuff. A slide ruler, divider, pencil and your brain, it helps to see the things you are about to invent more clear. I use it for basically contemplations
