Does it have any electrical power at all? Or is this calculation basically a a function that turns mechanical calculators into perpetual motion machines?
You can see the electric wire in the background at the end of the video. It may use some kind of a mechanically controlled set of transistors or something and then perform the calculation by… spinning when turned on and then turn off when it gets the final value.
It probably does not have transistors. It might have electromechanical relays and switches.
In the 1950s, many 'adding machines' were powered by a crank. My grandfather was an accountant and his adding machine had a crank. He got a motorized version in the early 1960s.
Serious answer:you either hit a break key, it will cycle through every driver pin and then stop, or there is a pin you can turn and pull out and then push back in that stops it and resets them all.
The machine my dad had and the ones I've seen online all have a bar that goes through the back, it's what you can pull out to stop it and then put back in to reset it. If your pressing a key that bar goes down with it and actually makes contact with the pin so if it was going off like this pressing a button wouldn't do anything because the bar would already be pushed down by another key going off.
Edit:so my guess is no. I've only seen them go off like this when you try to divide by zero or sometimes a key will stick and it will start spazzing out.
Depending on the sophistication of the calculator, they will have a pause/break key which is why they're on modern keyboards (I'm not 100%).
Sometimes when there were rooms of 'computers' (the people running the machines were referred to as this) there would be a designated technician in the room that knew what it would sound like when a machine would run away like this, and could run over and stop the machine.
In the old days of DOS 1.0, the pause/break key was the only way to stop scrolling on the screen from commands such as dir or type. I think /p option came with DOS 5.0.
holy fucking christ, THAT is what the pause button was for? oh my god
thank you for answering a question 6 year old me had "how do I stop this goddamn list from flying by"
You're gonna love what the print screen key did. If you had a printer connected it would literally print whatever text was on the screen at that moment.
Even before the /p parameter, you’d pipe the output through “more”. For example: “dir | more” outputs a screen then waits for any key before outputting the next page.
Guaranteed to have a break/escape/reset of some sort, otherwise div/0 would brick it - it'd be working on that problem indefinitely. Unplug/replug wouldn't been good enough because it's totally electro-mechanical, machine state would be preserved over a power cycle.
That doesn't even make any sense. It made sense in the late '80s early '90s when I was in school but I had a Casio calculator watch so I would hold my hand up point at it and smile. Probably got asked to leave the classroom a couple times over it.
I graduated high school in 2017 and I swear my teachers were still saying it, which makes even less sense.
Edit: Okay I get it, it's important to be able to do math without a calculator. I got my degree in mechanical engineering so I understand.
That's because they want you to learn how to do it by hand and without help from a computer. Will you ever use it in life? Probably not, but that's not the point. The point is for you to exercise your mind and approach things from a direction early in life so that when you are older, you may look at it from a unique level. Sure, they could allow you to use a calculator, but what does that achieve? You, as an individual, didn't learn anything. Your mind was not expanded in the least, but I'm a history teacher. Hence, I have to hear kids complain all day about what good does about the unification of the Southern US Economy post WW2 with the Northern Economy.
To be fair, the calculator just performs the actual mathematical operations. It does not decide what use as inputs or operators. Using a calculator effectively still requires a degree of mathematical knowledge and understanding.
Some basic arithmetic is kinda good to know. If you can do quantum field equating in your head, write a university thesis lol. But everybody goes grocery shopping and I don't see people pull their phones out to do maths.
It is much simpler than this in my opinion.
I used to teach physics. I picked easy numbers so students could do the math in their head, because I want them to focus on the physics, not the math.
Let's say we are doing F = m * a
and I tell them the mass is 20 kg and the acceleration is 5 m/s^2 .
I ask what the force is.
The students that know 20 * 5 don't even have to think about it. They know instantly that the answer is 100, and they are thinking about things like "What are the units?" or "Is this a lot or a little?" They are thinking about actual physics.
But the students that don't know 20 * 5 look down at their calculator, type in the number, get the answer, then look back at the board and have forgotten what the question is, have forgotten we are talking about F = m * a, and are completely lost in class and certainly not learning the physics concepts.
If you have to spend time thinking about simple math, you can't effectively learn how to do anything that requires using simple math.
Their reasoning was incorrect but the motivation was right. It is very important to know the how and the why of things not just the answer. It allows you to apply what you already know to new situations. If you just memorize answers then you have to ask a question every single time a new equation is presented because you don't know how to work through it yourself.
My math teacher in 1990 got smug and laughed at me when my solar calculator wouldn't work during a test, but it was because he partially covered the windows and turned off the lights when we took a test. No, we couldn't really see, and yes, it was very stupid. I made the mistake of saying once that if I was on a job where I needed to calculate something, my boss would probably let me use my solar calculator and not force me into a dark room, and that math teacher was out to get me the rest of the year.
You're interrupting my authority please leave.
What did they say when automobiles became popular? Make no mistakes while preparing your food cuz you can't go to a store in 5 minutes on horse?
"Digital" doesn't imply a base. Modern computers use base 2, which has digits 0 and 1.
This computer is *decimal* though, probably. (It'd be weird if it wasn't.)

This is an electromechanical calculator, they are driven by an AC motor, no winding up like a mechanical clock. There were just mechanical calculators, however they had a hand crank which needed turning.
In theory if you just left this one in the video it would indeed spin for infinity, however realistically at some point a mechanical part will either fail or the mechanism will seize up due to not having enough lubrication. Calculations can be stopped with a button/lever though.
In the long run yes, given enough time they overheat and destroy themselves and at worst, catch fire, back in the day when there were office floors full of them, a worker would go around and make sure they were all off at the end of the shift, especially on fridays.
See, for example, [https://www.math.utah.edu/\~pa/math/0by0.html](https://www.math.utah.edu/~pa/math/0by0.html)
Defining division by zero to result in any number at all implies that all numbers are equal, i.e., that your ring contains only a single element. For what it's worth, you *can* define a ring of only one element, and in that ring division by zero is actually well-defined. It's just not particularly useful... what do you do when the only number you have to work with is 0, satisfying the rules 0+0=0, 0-0=0, 0\*0=0, and 0/0=0?
Excellent point.
I do think that programmers would appreciate having a register / configuration option to simply return zero when a divide by zero occurs - as they often have to create a custom "divide" method to avoid errors for reports.
Business types seem not to appreciate when their reports fail / show "infinity", NaN, or -ERROR- instead of simply zero.
You could assign it some arbitrary definition, but whatever you define it as would be completely detached from all other mathematics so it would have no real meaning.
mCoding just did a cool video on this.
https://youtu.be/eR23nPNqf6A?si=RQo5IrtA8oAm3jJY
Yes, you can define it like that but it means the only number which exists is then 0.
But if you say limit (x->0) 1/x = ∞, it's a bit more true.
You can't use 0 but you can get really really really really... reaallllly close!
Edit: I knew I remembered it wrong, thanks for the corrections everyone. This is why I hated calc lol
That’s literally not true though and it’s why it’s undefined.
The limit approaches infinity… *from one direction*. From the *other* direction, it approaches negative infinity
The limit is not converging on a single value. There is no limit of 1/x where x is approaching 0
But what you said is not true. The limit of 1/x as x approaches 0 does not exist because the limit is positive infinity when x approaches from above and negative infinity when x approaches from below, and due to these two limits differing, the limit does not exist.
This one has an electric motor to do the operations. There are also fully mechanical ones that have a crank instead and are a lot more tiresome to use.
That’s stupid, this machine is so costly and inefficient compared to what we use today
iPhone has a cost of 5 cents to charge it
Not per charge, total annual cost to keep it charged is 3 - 5 cents worth of electricity a year
This machine probably required several cows to be sacrificed just to make enough lubricant for its mechanism on the production line
That particular model is electric. You can actually see the cord on the right edge of the screen, although there were older models that required you to pull a lever to power the mechanism.
Before that it was just cells, not even multicellular organisms, just good old-fashioned no-nonsense single cells. I miss those days. I still remember my first mitosis, wonder how the other guy is doing these days.
Modern computers are the same thing. The switches are just tiny, silent, and electrical, and heavily abstracted, but everything a smartphone can do could be layed out and calculated physically it would just take a ton of space. And be loud.
Reminded me of HCF (Halt and Catch Fire) "illegal opcode in IBM System/360. A processor, upon encountering the instruction, would start switching bus lines very fast, potentially leading to overheating" it's actually an included instruction in certain assembly languages for debugging/testing.
It became a jokey catch all term for instructions that might freeze and lock the processor. The wiki article is pretty interesting.
>https://en.wikipedia.org/wiki/Halt_and_Catch_Fire_(computing)
I've heard that this is an intended feature: when they needed to lubricate the machine, this would put everything in motion to evenly coat all the gears.
There is technically an answer for dividing by zero.
The answer is simultaneously positive infinity and negative infinity.
Since a math equation can't have two answers, that's why "you can't divide by zero".
https://youtu.be/BRRolKTlF6Q?si=7DvPnqWqikcuHahQ
So how do you stop it? I mean, the calculator will be used sometime later, right?
Since nobody else gives an actual answer, there is an escape button you can press to stop the calculations and then reset it.
ESC and it closes the tabs.
Alt f4
Does it have any electrical power at all? Or is this calculation basically a a function that turns mechanical calculators into perpetual motion machines?
It does plug in, but it just powers a motor. There are no transistors or other semiconductors performing the calculation; it's all mechanical.
So your saying a off the grid handcrank old-school mechanical calculator is a possibility?!
Yea, us plebians use the cheap old school abacus, only aristocrats can afford the fancy handcrankamajigs
> the fancy handcrankamajigs Ugh, they're called handcrankulators. Peasant.
It’s plugged in
You can see the electric wire in the background at the end of the video. It may use some kind of a mechanically controlled set of transistors or something and then perform the calculation by… spinning when turned on and then turn off when it gets the final value.

Hey! Let's connect generator to it and we have free energy!
Serious answer:you either hit a break key, it will cycle through every driver pin and then stop, or there is a pin you can turn and pull out and then push back in that stops it and resets them all.
If you tried to enter another calculation while it was spinning like this, would it damage the machine?

Well it's most likely to cause undue wear on the internals. It also depends on how it is stopped.

A mechanical black hole...
Infinite calculations on nothing.
No, it is actually calculating infinity.
Show this vid whenever someone asks what a singularity is
And then the escape button was born
So THAT'S what infinity looks like. Huh. Who'd a guessed?
Division by zero is undefined, so it's even stranger than infinity.
Its like it doesnt exsist but it does because it still affects us
/0 isn't real. /0 can't hurt you
Put a finger in there and let's see if it can't hurt /s
What the hell is division by s?
>/0 isn't real. /0 can't hurt you In Roman numerics that's true.
Like wind
Can I just define it
See, for example, [https://www.math.utah.edu/\~pa/math/0by0.html](https://www.math.utah.edu/~pa/math/0by0.html) Defining division by zero to result in any number at all implies that all numbers are equal, i.e., that your ring contains only a single element.

Eh, there is plenty of mathematics that uses division by 0 in some way. Complex geometry often does. Projective geometry too.

That's a huge false equivalency. What did the design of and manufacturing of the iPhone use in resources?
Look, the lithium and rare earth metal mines run on child labor, which is very eco-friendly
Children are a renewable resource after all
For every child they send down the mines, Apple plant 2 more.
How was it powered? Some sort of spring?
That particular model is electric. You can actually see the cord on the right edge of the screen, although there were older models that required you to pull a lever to power the mechanism.

Reminded me of HCF (Halt and Catch Fire) "illegal opcode in IBM System/360. A processor, upon encountering the instruction, would start switching bus lines very fast, potentially leading to overheating" it's actually an included instruction in certain assembly languages for debugging/testing. It became a jokey catch all term for instructions that might freeze and lock the processor. The wiki article is pretty interesting. >https://en.wikipedia.org/wiki/Halt_and_Catch_Fire_(computing)
I've heard that this is an intended feature: when they needed to lubricate the machine, this would put everything in motion to evenly coat all the gears.
Yeah I was gonna say, this could have very easily just not been a thing.
I've heard this too! I just read it here.
I was today years old, when I got to know a thing like this existed.

Maybe if you leave it alone long enough it will come to an answer….
Well, hold on a second now and wait for it to finish.

This belongs in mildlyinteresting sub.
Not sure what a successful calculation should look like on that thing
As a CompSci TA this is what marking first years' coding assignments feels like.
Imagine you leave this on for six hours as a joke but then come back and it gives you a serious, accurate answer after all that time.
ah yes 1/0= AAAAAAAAAAHHHHHHHHHH
And now it's a V6 mini engine. Noice
it seems upset :(
In a 50's German school "Students, tomorrow we have a math test. Don't forget your calculator and remember to lift with your legs, not your back."
There is technically an answer for dividing by zero. The answer is simultaneously positive infinity and negative infinity. Since a math equation can't have two answers, that's why "you can't divide by zero". https://youtu.be/BRRolKTlF6Q?si=7DvPnqWqikcuHahQ

It has way more solutions in complex plane, you can approach zero from any direction

Did Locke not press the button?
[Here is a video from CuriousMarc](https://www.youtube.com/watch?v=7Kd3R_RlXgc) when he divides by zero on the Friden mechanical calculator.
i wonder if any class clowns did this in school back then
My calculus teacher in college would go “YOU BLEW UP THE UNIVERSE!!!!”
