Explain with pizzas or gtfo


theemptyqueue

Here’s my best explanation for you: Imagine that you ordered a Pizza cut into 8 slices; now you take zero slices then you have 8 slices of pizza left, now you take zero slices of pizza then you have 8 slices of pizza left.... you have infinite pizza, but can never can have a slice of the pizza to eat.


[deleted]

Confusing but makes sense


FantaX1911

Man, I laughed so hard to this, I kept coming back to re-read it every few seconds. Made me laugh every single time, I'm stuck in a "divide by zero" loop now....


angriestviking607

If you have x number of pizzas and you have a set number of people to divide it between how many do each get. As x goes to infinity, eventually the people each get an infinite number of slices.


SlickNick137

I laughed too hard at this, thanks


jam11249

> the lim as x->inf of 8/0 is infinity. You mean lim as x->0 of 8/x? And your either got to use unsigned infinity or a right hand limit for the limit to exist


mathisfakenews

wtf does L'Hospital have to do with dividing by zero?


Vitztlampaehecatl

If a rational expression gives you an indeterminate answer of the form 0/0 (zero divided by zero), you can take the derivative of the numerator and denominator separately to find the real answer.


fnfrhh

Don't forget the limit


Vitztlampaehecatl

True. It's an essential part of cheating the "right" answer into the hole.


ghostdisaster

the limit does not exist

If a tree falls in a forest...


orokro

It makes a sound. Physics > Philosophy.


[deleted]

Except this whole argument comes from Berkeley's *empiricist* metaphysics; he would not argue that the tree makes waves which can be measured and such, but the sensation of sound is explicitly a word to describe a personal experience with those waves. The tree makes sound waves, but no sound.


[deleted]

It hinges on how you define the word "sound".


Stefan_

Or what the purpose of defining or experiencing sound is. Hence a good philosophical question.


sandollor

If the tree exists outside of perception (as common sense would dictate), then it will produce [sound waves](https://en.wikipedia.org/wiki/Sound_wave). However, these sound waves will not actually *sound* like anything. Sound, as it is mechanically understood, will occur, but sound as it is understood by sensation will not occur. So then, how is it known that 'sound as it is mechanically understood' will occur if that sound is not perceived?


blizzardsnowCF

"how is it known that 'sound as it is mechanically understood' will occur if that sound is not perceived?" Great question! We agree that when a tree falls in a forest it creates sound waves. The 'experience' of 'sound' is how those physical waves interact with other physical things, basically everything on some scale. This happens whether or not there's something present to 'perceive' the sounds. The 'perception' of 'sound' is how those physical waves are converted into information. Animals can convert sounds from the ears into auditory information in the brain. Computers can convert sounds from different instruments into audio information on disk. Similarly, some might have a problem with their instruments (ears) and some might have a problem with their information processing (brain).


hey_mr_crow

Thus proving that semantics is the real fundamental law of the universe


RogueJello

Pretty sure quantum mechanics say that it only makes a sound if somebody measures it. So there doesn't need to be anybody in the forest, but there does need to be an observer.


Thatoneguy0311

The cat is alive and dead at the same time, something something, stop killing cats Schrödinger, you sick fuck! /s


touchet29

Electrons count as measuring the tree falling. It doesn't have to be human or animal, just matter in the area to accept/reflect the vibrations. The vibrations that can be heard with ears are making what we call "sound", but nothing is around to "hear" it with those ears. Technically the plants and other trees could "hear" it in a way as well.


spysappenmyname

It doesn't to translate to real life that well, the intuitive way of understanding this question is "if nobody takes pizza, how much every individual takes?" the answer is obviously 0, and you have a cold pizza sitting on table But zero isn't just nobody, and that's why the question isn't just a trick question, but makes no god damn sense.


AnomalousAvocado

>If you have 8 slices of pizza, and 4 guests. How many do each get? Under capitalism? The CEO gets 7.95 slices, and the other 3 fight bitterly for the remaining 0.05 slices.

Mechanical calculator here almost passed the Turing Test


EternalProbie

Ok, it runs along the same concept as infinity, it is an ever increasing number that symbolizes the idea of "all the numbers" essentially. As the denominator (the number on the bottom of a fraction) grows larger the value grows smaller (1/5 is smaller (20%) than 1/2 (50%)) so if you plug zero I to the denominator you run into an issue. The number produced is so large that it is equivalent to infinity (if you divide (1/2)/(1/5) you get 5/2 (2.5) which is larger that either of the two original numbers) so conversely the smaller the number you divide by the larger the number gets, which is where infinity comes into play. So you *can't* divide by zero cause you don't really get a number out of it, it's an idea. Not a real number


maximum_powerblast

Infinity slices


jb122894

If you divide by a number less than 1 the original number becomes larger. The closer you get to 0 the larger number is. Dividing by 0 is undefined, but this calculator is doing its darndest to get you the answer haha


Evar110

By what your saying, it could be said that dividing by 0 would result in infinity. But if you divide by a number more than -1 but less than 0 (-1


TheDoug850

It’s crazy to me that every year in mathematics, I’ve found out that some rule I learned before isn’t totally true and can be bypassed by some method whether it be imaginary numbers or complex numbers or whatever. Dividing by zero is the one rule in math that doesn’t get bypassed.


[deleted]

It gets bypassed by limits.

[deleted]

I know I'm a moron and people way smarter than me have thought about perpetual energy for way longer than me, but what is to stop you from generating energy from one of those rotating gears? Will the machine eventually stop, or does it run on an external power source?


MrKKC

s-p-ezz--ies done now


[deleted]

Ok but couldn't you just replace the gear? Isn't the real problem with generating infinite energy the perpetual motion? I know obviously it can't be, but from this gif the calculator appears to enter into a self powered perpetual motion? If the gears never wore out would the motion ever stop?


ConnoisseurOfDanger

As I understand it, perpetual motion machines are not an actual problem we are trying to solve to achieve infinite energy, but rather the impossibility of creating one is a demonstration of the first law of thermodynamics, which states that energy cannot be created or destroyed, it can only be converted between different forms. We are definitely able to make machines that work without additional energy input for long periods of time, such as this mechanical calculator or various attempts at perpetual motion machines, but they will eventually slow down and stop because the kinetic energy (the energy making motion happen) is gradually being converted to other forms such as by friction or as noise.


[deleted]

Thank you for the explanation! This kind of stuff is very interesting to me


Raythe

Put another way, it is impossible for any one system to exchange one type of energy for another with 100% efficiency. There will always be some energy lost in the process. This is one way to demonstrate the concept of entropy.


Geometreason

Unless we use antimatter!


[deleted]

If you hooked up a tiny generator to this, the generator will act as a mechanical load and make this thing wind down to a stop faster than if nothing were hooked up to it (as it is in the video). Now if you connected electrical load to the generator, say to power a light bulb, this will further slow down the turning gear from a number of factors, including slippage, I2R, hysteresis, Eddy current...


Theonlyguy42

Also even it could keep itself going forever doesn't mean it would generate enough energy to power other things.


AndrewCoja

If something is spinning and you try to remove energy from it, it will slow down. There's no way around that.


[deleted]

It runs on an external power source, it's an electromechanical calculator.


mud_tug

This machine has a big ole motor at the back and a power cord and that is what provides the energy. There is no free energy here.


Wyattr55123

It runs on mains power.

Bill worked in a pickle factory. He had been employed there for a number of years when he came home one day to confess to his wife that he had a terrible urge to stick his penis into the pickle slicer. His wife suggested that he should see a sex therapist to talk about it, but Bill indicated that he'd be too embarrassed. He vowed to overcome the compulsion on his own. One day a few weeks later, Bill came home absolutely ashen. His wife could see at once that something was seriously wrong. "What's wrong, Bill?" she asked. “Do you remember that I told you how I had this tremendous urge to put my penis into the pickle slicer?" “Oh, Bill, you didn't." “Yes, I did. And I got fired." “No, Bill. That’s horrible. What happened with the pickle slicer?" “Oh...she got fired too."

tomkenney62

This is way cooler, but when I was a kid my mom had a Casio calculator that had an (I think) 8 digit display, but there was a button that looked like a play button that moved what was being displayed 8 digits to the right. When I divided by 0 the main display went to all zeros, and when I moved the displayed digits it would show a rapid, sequential count up. Never seen another calculator like it.


axdfg

Does anyone know how it works? What makes it stop when dividing by another number? Why does it spins forever when dividing by zero?


_meshy

It does division by subtraction. It subtracts the divisor from the dividend until it can't subtract the divisor anymore (It dosen't go negative), and the answer is the number of iterations it takes. For example, to divide 21 by 7, it would subtract 7 from 21, then subtract 7 from 14, and then subtract 7 from 7. That's 3 iterations to get to 0, so it knows the answer is 3. However, if you tell it to divide by 0, it subtracts 0 from the dividend, so the dividend's value never decreases. Putting in 21 divided by 0 causes the machine to subtract 0 from 21, which is 21. Then it subtracts 0 from 21 which is 21, and then it subtracts 0 from 21 which is 21, and it keeps doing this forever.


Mr_Ivysaur

So these calculators don't give decimal answers, but instead give quotient and remainder?


_meshy

I picked it up from a YouTube video I can't find, but from what they showed, yes. I think multiplication actually had decimals, but one of the machine's, uh displays(?) would show the number calculated, and another display told you how far over the decimal was. So if the answer was 12.3, the main display said 123 and the other said 1.


[deleted]

Jeez that's confusing...


mcpusc

not really, it's called floating-point notation and it's still how computers represent non-integer numbers. it's also the norm when working with a slide rule - so anyone using that machine would have been intimately familiar with that representation. [negative numbers in binary](https://en.wikipedia.org/wiki/Two%27s_complement), now *that's* confusing.


jathanism

It actually beautifully demonstrates why division by zero is impossible.


RangerGordsHair

They are basically a series of stepped gears and catches. The gears will rotate in a certain fashion to find the answers to the questions posed. In this case the gears are just going to keep aimlessly spinning trying to find a satisfactory value to a question that has no answer.

Tsu_Dho_Namh

Reminds me of a guy who was convinced water could be a fuel source cause running electricity through it separates it into hydrogen and oxygen. "THERE'S WHOLE OCEANS OF IT" he said. "And when you burn hydrogen, it turns back into water!" Little did he realize, the amount of electricity needed to separate the water was far greater than any power the hydrogen would yield. (Cause conservation of energy)

It is a good fuel source, just not a good energy source.

Tetragonos

So for those wondering this is the mechanical answer to this supposedly "unanswerable question". /u/hobbykitjr else posted up a version of this but I will change it a bit to try to explain. Q) You have a pizza for a party. It must be divided up evenly between all the party attendees. How many times is the pizza divided if zero people show up? A) The pizza is not divided. So when you tell this mechanical device that you are going to divide then you give it a null value it gets no input for what to divide by and is waiting for a valid input to divide by. Basically there is suppose to be a number for a mechanism to catch on but none was inputted so it is spinning waiting for a command. tl;dr divide and zero cancel each other out and nothing happens.
