Guys, we need a legitimate pineapple mathematicians opinion here, not some lousy banana or watermelon mathematicians, you should take your low level of maths to a different business, like railroad engineering for example...
The spacing of the black dots is closer when carved in that way. So he just looks for a line of dots with the closest spacing and follows that line. No need for maths. The closer the dots, the less of the good pineapple flesh is wasted.
He cut it like that not because its of a mathematical nature. But of appealing to the customer. I make it look good. Thus making you come there and buy the pineapple more....
Why did he do it mathematically? Do you see the little strips left behind? That's all pineapple that would have been cut off if done without spiraling it like that. Where does the math come in you may ask? LESS pineapple removed EQUALS MORE pineapple to eat. Not that hard to figure out.
*****, if you noticed, I said "one of the highest-yield methods to PEEL", not EAT. What you mentioned doesn't include peeling at all. So I don't see where I'm wrong.
No we fucking don't. And if you do, then you're an idiot that probably doesn't know how to peel a pineapple. Who the hell feels good about having a scalded tongue after eating those dots? No one.
Mary Wence I have a very delicate tongue, and I eat the dots with no problem. The problem is in the core, not in the dots. Now... People can perfectly eat the seeds in the watermelon, the core of the apple, and all that parts discarded for idiots who can waste just because.
Mary Wence Don't agree on the scalded tong, it's the core, not the dots what makes it scald. But i do agree with you on the fact that only idiots will eat them.
Jonnas i think @Amir shachar is right ,it probably have the best waste/time ratio to peel and sell. he could sit there and poke out each and every one of those 'eyes' but that would take more time to do and the pineapple he saved is probably not worth missing out on another customer. he saves time plus offers the customer the optimal goods for the money.
I just want to buy a generic knife to cut my eyes, so that I'll stop wasting my time looking people talking about math, while looking at a guy cutting a pineapple on youtube.
the separation of the octagons having "the black dot" in the middle creates a perfect alignment and distancing in between each dot making his spiral carvings more efficient ,making it easier to consume and also giving a better look to the fruit itself.
In my opinion, each dot was in hexagon. To minimize the flesh wasted and cut efficiently, with minimum cuttings, imagining the hexagons, he cuts through the diagonal line, from top left side to the bottom right side, which directly becomes next top left side. This hexagon structure makes it possible the dots to be removed at a time as long as possible.
As the black holes are spirally lined around the fruit, cutting those hole out spirally will be the quickest, most efficient and least wasteful way of cutting the holes out.
that is correct. we find the golden ratio almost everywhere in nature and that is indeed intriguing. Amazingly, if you count these spirals, your total will be a Fibonacci number. Divide the spirals into those pointed left and right and you'll get two consecutive Fibonacci numbers. You can decipher spiral patterns in pinecones, sunflower and cauliflower that also reflect the Fibonacci sequence in this manner. beautiful.
James Saunder .5 cents? 20 for just 1 cent? nice!!! ;) I understand Bell made the same mistake once with their charges per text - Advertised .05 cents per text. Some people were pissed when they charged 5 cents...
i have a feeling the reason he cut the eyes out in the diagonal motion is because the eyes are positioned according to Fibonacci sequence, the diagonal method is the best way to cut the crap out of the pineapple but maintain the most pineapple. There is a maths lady on youtube somewhere that explains Fibonacci.
wow, that's one very fast, economical and effective way of peeling the skin and removing the eyes of a pineapple using special tools. i have always use an ordinary knife and it's one hell of a job.
Ok, I'll give it shot.. If you go to time 1:00 and pause it you will see how the dots are arranged. If you look closely the dots going in a horizontal way are further away going down then if going the vertical way. which means you are taking less pulp and you are also making fewer strides. . If you were to go Horizontally you will take more pulp do to the distance from spot to spot downward and on top of that you will have far far far more strides as the spots side to side are to close thus eating more pulp.. Now this is just looking at it in a math way but the vendor MIGHT not even know this.. This might just be do to the comfort on the wrist while cutting and turning it.. But I'm sure they figured they are eating to much pulp after every Horizontal stride. If you measure the distance between every vertical gap after a cut has been made you will see its just about the same distance the spots are in side by side if cutting Horizontally that is.. Thus Horizontally you are basically eating through completely all the way around leaving no extra pulp compared to vertically. I hope that makes sense from a visual perspective as I cant do actual numbers unless I have the that pineapple with me.. Why? maybe also he is trying to step up and away from other competing vendors
Because if he removes the dots proper circlewise the gap between two dots are maximum by which maximum mass would be lost also the gap between it and the dot diagonally adjacent to it is very less if they peel circular.. even while peeling vertical maximum cuts will have to be, perfectly saying exactly double .. so for lesser loss of mass and minimum effort (by covering maximum dots in one go) he is peeling it that way ..
this is how my family does it. I think all southern chinese know about it? it's the most economic way and you get to keep the sweetest part of the pineapple, sooo yummy!
It's the fibonacci sequence (0,1,1,2,3,5,8,13,...). There are 8 spirals going from top to bottom from left to right. If you try counting the spirals going from right to left you should get 13 spirals, but I can't really tell from the video.
It's because having plant parts grow one phi (the golden ratio) of a turn between each other maximizes the distance between each plant part and every other plant part that has grown and will grow in the future. This allows each plant part to grow as large as possible without having to "squeeze" adjacent plant parts so much. Vihart does a wonderful video on this called: Spirals, Fibonacci, and Being a Plant.
its the fibonacci spiral, you can find the same spiral on all sorts of plants. It corresponds with a series of numbers: 0 1 1 2 3 5... 0 plus 1 equals 1, 1 plus 1 equals 2, 2 plus 3 equals 5, and so on. you get the spiral by making squares the size of all the numbers in the sequence on a grid starting in the middle and you draw circular arcs connecting the opposite corners of the squares to get the same spiral that appears on many plants.
mathematics here is referred to the Fibonacci sequence or numbers, the same principle applies to pine cones, sunflowers and other naturally occurring sequences. The numbers follow 1, 1, 2, 3, 5, 8, 13.... it goes on to create a spiral.
the thing is that the number of spirals one way is the previous consecutive number to the number of spiral in the other way wiki it the pineapple is referenced a one of the fruits that follow this form. for instance if you count 8 spirals one way there will be 1 spirals the other way. as for the golden mean the ratio of consecutive fibinocci numbers is an approximation for phi that is F(n)/F(n+1)=phi as n tend towards infinity.
Hmmm, maybe: Cutting in a spiral means less work than cutting downwards because you would have to make many more cuts just going downwards. Also I hear pineapples naturally have a spiral 'grain' like wood does and we all know to cut with the 'grain'.
We owned a pineapple canning factory in Bangla Desh..Pineapple cutters worked all night to get the pineapple ready for canning for the morning shift workers..They used sickles to peel and remove the eyes..their dexterity was commendable.
I'm going to guess that if he's selling fresh pineapple by the pound, he has a heavy incentive to get as much fresh fruit out of each pineapple as he can.
Well, if you take pie π and multiply it by the number of spine holes a pineapple usually has by genetics, then divide it by the number of diagonal cuts it takes to take out all those cuts and then add the number of pie recipes possible for pineapple and subtract the number of other fruits that are named apple or are fruits, you can clearly see how much of a gardening tool is to be used to poke out those holes.
the fibonacci sequence and golden ratio phi spiral in nature shows that ALL organisms grow in spirals (in someway or other), it's a result of a torus shape in which physical energy moves
The tool that you use to remove the black dots, where can I get one? I live in Montreal, Quebec Canada. Does it have a special name for this tool. Black Dot remover tool.... LOL
i know all about this, i think... the multiplication of xt for xt is the triangle of the numbers divided by the division of the odds coming from the multiplication of xt32m for 100:xt-t :-)
All I know is that is considered the best way to peel a pineapple, like, officially. I think I saw it on Martha Stewart or something. And that equals, Math.
There is 2 pineapple sellers on a bridge one cuts a pineapple in half and gives you a spoon the other takes double the time but makes a nice pattern in your pineapple. obviously you get the patterned one right
that's how my family would peel the pineapple since it's the best way of getting rid of the eyes (black dots). dots can sometimes make my lips & tongue itchy. due to the geometrical design, cutting it diagonal along the dots is the best way. plus the spiral look makes it unique & when you slice it horizontally, it gives that flower shape. digging the dots one by one would be time consuming & peeling the fruit deep enough until the dots are gone would be a waste of such a succulent fruit.
jay thats convincing ... but the related question to his answer was: "guess why he does it that way?" (or kinda like that) ... and ... that matter has actually nothing to do with fibonacci-numbers!

The pineapple has a fibonacci pattern. Pure mathematics.
After calculating the imperial quadrilateral squared cube of this video I have finally realized the paradox of our existential dilemma.
Lmaaoo
TheDigitalPillars ahaha
😂😂😂superfantabulous answer
I graduated in pineapple mathematics so I understand what he´s doing
hahahahahahaahahah
SORRY I DON'T UNDERSTAND PINEAPPLE MATHEMATICS CAUSE I GRADUATED ON WATERMELON MATHEMATICS. MY QUESTION IS ARE THEY SIMILAR MATHEMATICS?
Yeah I studied literature. I can count to 7. He cut 1 pineapple.
Does that equal half a watermelon?
I got banana mathematics here and I can't figure out how to solve that, and you want to figure it out with watermelon level? ha.
Guys, we need a legitimate pineapple mathematicians opinion here, not some lousy banana or watermelon mathematicians, you should take your low level of maths to a different business, like railroad engineering for example...

"Hey!
Mr.Tallyman...?!"
what fruit salad of an education
I have to do homework and I'm watching videos on how to cut pineapples
didnt knew that jesus too had to do his homework :)
losthorizon21 lmao!!!!
me too...I have many project to do and I'm watching this video......
oh my god same
Me too😂😂
he took away half the pineapple with the eye removal tool.
tlkchew Negative. Believe it or not, he kept from losing as much actual meat.
Sponge bob is gonna be pissed when he gets home.
In Soviet Russia, pineapple peels you.
Lucas Twoson lolollololololollolol
Hahaha, too much brah
In Trump's world,all pineapples have a small loan of a million dollars
Soviet russia isnt exist 😂
+Yashith Janithra *doesn't 😂
The spacing of the black dots is closer when carved in that way. So he just looks for a line of dots with the closest spacing and follows that line.
No need for maths. The closer the dots, the less of the good pineapple flesh is wasted.
Why did he edit this in Movie Maker?
Can you find an aesthetic reasoning for that?
YO! Give me that fucking pineapple!
Nice my family likes pineapple; Fibonacci sequence applies as the Fibonacci numbers are the sums of the "shallow" diagonals of Pascal's triangle.
He cut it like that not because its of a mathematical nature. But of appealing to the customer. I make it look good. Thus making you come there and buy the pineapple more....
Why did he do it mathematically?
Do you see the little strips left behind? That's all pineapple that would have been cut off if done without spiraling it like that.
Where does the math come in you may ask?
LESS pineapple removed EQUALS MORE pineapple to eat. Not that hard to figure out.
No, that's actually one of the highest-yield ways to peel it.
***** yes, the 'watermelon cut ' style suck and gnaw at the skin eventually method. Preferred by pineapple aficionados.
*****, if you noticed, I said "one of the highest-yield methods to PEEL", not EAT. What you mentioned doesn't include peeling at all. So I don't see where I'm wrong.
in mexico, we eat those motherfucking dots.
No we fucking don't. And if you do, then you're an idiot that probably doesn't know how to peel a pineapple. Who the hell feels good about having a scalded tongue after eating those dots? No one.
Mary Wence
I have a very delicate tongue, and I eat the dots with no problem. The problem is in the core, not in the dots. Now... People can perfectly eat the seeds in the watermelon, the core of the apple, and all that parts discarded for idiots who can waste just because.
Mary Wence Calm down. My mom is from Peru puts the pineapple extras in hot water and adds sugar to make juice so there is less waste.
Mary Wence Don't agree on the scalded tong, it's the core, not the dots what makes it scald. But i do agree with you on the fact that only idiots will eat them.
***** I eat the whole thing.
Watching random vids on youtube and this has just Ruined my mood because I know I should be revising for my maths and physics exams
This is a man who has the right tools for the right job... That was fantastic to watch just for its speed and efficacy.
He can peel/score a pineapple faster than a knife that means more profit. Ka-ching.
it optimizes the amount of pineapple left?
Nop, He clearly wasted a lot of pinneapple... It's fast tough...
Jonnas i think @Amir shachar is right ,it probably have the best waste/time ratio to peel and sell. he could sit there and poke out each and every one of those 'eyes' but that would take more time to do and the pineapple he saved is probably not worth missing out on another customer. he saves time plus offers the customer the optimal goods for the money.
maybe Fibonacci spiral?
I want to buy the knife for cutting pineapple eyes
I just want to buy a generic knife to cut my eyes, so that I'll stop wasting my time looking people talking about math, while looking at a guy cutting a pineapple on youtube.
the separation of the octagons having "the black dot" in the middle creates a perfect alignment and distancing in between each dot making his spiral carvings more efficient ,making it easier to consume and also giving a better look to the fruit itself.
I was expecting the Fibonacci sequence but I counted 9 rows.
It's really cool to see those hexagons form a spiral pattern on that pineapple. I've never thought of this before. Thanks
BECAUSE IT LOOKS COOL!
There is no mathematical reason, he just wanted it to look nice.
Logarithmic spiral or golden spiral.
In my opinion, each dot was in hexagon.
To minimize the flesh wasted and cut efficiently, with minimum cuttings, imagining the hexagons, he cuts through the diagonal line, from top left side to the bottom right side, which directly becomes next top left side. This hexagon structure makes it possible the dots to be removed at a time as long as possible.
He does it this way cause its the quickest way and he doesn't waste to much edible fruit.
As the black holes are spirally lined around the fruit, cutting those hole out spirally will be the quickest, most efficient and least wasteful way of cutting the holes out.

dude i want those tools!!!!
Took me like 30 minutes when doing this with a small knife.
A knife is certainly better for this job. Faster too if you are a pro. Mathematics is very simple. Pineapple bought for 50 cents, sold for 5 dollars.
James Saunder .5 cents? 20 for just 1 cent? nice!!! ;)
I understand Bell made the same mistake once with their charges per text - Advertised .05 cents per text. Some people were pissed when they charged 5 cents...
where can i buy the same tools?
i have a feeling the reason he cut the eyes out in the diagonal motion is because the eyes are positioned according to Fibonacci sequence, the diagonal method is the best way to cut the crap out of the pineapple but maintain the most pineapple.
There is a maths lady on youtube somewhere that explains Fibonacci.
is it Vihart
Music by 2 face
I suppose the purpose of the spiral cut is that it leaves a slightly higher volume of pineapple behind. Very cool. Thanks for the video.
my trypophobia made me like freak out inside when i saw the pineapple with the black holes in it... yup
violette sark OMG same here. Anything with a lot of holes makes me sick. This is totally off subject but my daughter's name is violette too
Denise V oh cool :)
violette sark my face felt itchy and like it was going to melt watching the black holes.
ysssuhi that sucks
I finally understand the universe after watching this.
An equilateral spiral or Fibonacci sequence spiral
nice one
wow, that's one very fast, economical and effective way of peeling the skin and removing the eyes of a pineapple using special tools. i have always use an ordinary knife and it's one hell of a job.
Its not mathematics. You just save fruit by doing this method. It also might be a little bit faster than the normal method.
+Justin Miller it's definitely not faster than the normal method. I work with fruits and it takes us half the time.
Ok, I'll give it shot.. If you go to time 1:00 and pause it you will see how the dots are arranged. If you look closely the dots going in a horizontal way are further away going down then if going the vertical way. which means you are taking less pulp and you are also making fewer strides. .

(P + k)^2 = yummy
Because if he removes the dots proper circlewise the gap between two dots are maximum by which maximum mass would be lost also the gap between it and the dot diagonally adjacent to it is very less if they peel circular.. even while peeling vertical maximum cuts will have to be, perfectly saying exactly double .. so for lesser loss of mass and minimum effort (by covering maximum dots in one go) he is peeling it that way ..
It's just Fibonacci
Getting the most to eat out of the fruit.....Im gonna try that next time I get one....Nice job!
I just want the answer as to where I can buy a set of those 2 special implements he used they are cool!
The Golden Ratio combined with Simple Harmonic Motion.
Scary the way he gave the finished product pineapple back with a sharp knife pointing straight to his customer!!!
he gets paid every time he sells a cut up pineapple, you do the math.
this is how my family does it. I think all southern chinese know about it? it's the most economic way and you get to keep the sweetest part of the pineapple, sooo yummy!
It's the fibonacci sequence (0,1,1,2,3,5,8,13,...). There are 8 spirals going from top to bottom from left to right. If you try counting the spirals going from right to left you should get 13 spirals, but I can't really tell from the video.
Glad I can help :) Just spread the info around to other people that have the same problem like I do and its all good :D
It's because having plant parts grow one phi (the golden ratio) of a turn between each other maximizes the distance between each plant part and every other plant part that has grown and will grow in the future. This allows each plant part to grow as large as possible without having to "squeeze" adjacent plant parts so much.

That's EXACTLY what I was thinking.
i never seen that tool to remove that dots. but looks handy
the only mathematical equation that I see here is the money in his pocket after a full day of work peeling pinneaple for tourists.
Amazing the best , I ever seen,
he peeled it that way cuz it looked cool and tourists like cool things
Does it have to do with the golden spiral????????
I'm loving this pineapple device.
mathematics here is referred to the Fibonacci sequence or numbers, the same principle applies to pine cones, sunflowers and other naturally occurring sequences. The numbers follow 1, 1, 2, 3, 5, 8, 13.... it goes on to create a spiral.
So what technique you use??? Sand paper to sand it precisely???
A Chinese kid was cutting a pineapple
That's why it involves math.
If u think this is wasteful, just look at the cut pineapples from superstore. The whole outer cylinder is cut away in one swoop.
What a very useful pineapple cutter.
this the cleanest way of manually peeling pineapple with less waste!
The boss told him to cut it this way otherwise he would get Fibonaccied
the thing is that the number of spirals one way is the previous consecutive number to the number of spiral in the other way wiki it the pineapple is referenced a one of the fruits that follow this form. for instance if you count 8 spirals one way there will be 1 spirals the other way. as for the golden mean the ratio of consecutive fibinocci numbers is an approximation for phi that is F(n)/F(n+1)=phi as n tend towards infinity.

A man and his tools..Mad skillz !!
well, this solves most of my problems ! thanks :)
So we must find a mathematical solution.... Helll naawwwwww
We owned a pineapple canning factory in Bangla Desh..Pineapple cutters worked all night to get the pineapple ready for canning for the morning shift workers..They used sickles to peel and remove the eyes..their dexterity was commendable.
There's mathematics involved in everything.
i shall say it in a rhyme (some what)
less work, faster pace, fun for tourists, plus not any waste.
i think i got it :)
I don't know if mathematics had something to do with it, but I like how he leaves just the good stuff.
I'm going to guess that if he's selling fresh pineapple by the pound, he has a heavy incentive to get as much fresh fruit out of each pineapple as he can.

@ludwiglaoshi is it the fibonacci sequence?
There is 2 pineapple sellers on a bridge one cuts a pineapple in half and gives you a spoon the other takes double the time but makes a nice pattern in your pineapple.
obviously you get the patterned one right
i don't think so, we just need a rotating shaft moving back and forth, and a fixed cutting edge to peel off the black dots.
that's how my family would peel the pineapple since it's the best way of getting rid of the eyes (black dots). dots can sometimes make my lips & tongue itchy. due to the geometrical design, cutting it diagonal along the dots is the best way. plus the spiral look makes it unique & when you slice it horizontally, it gives that flower shape. digging the dots one by one would be time consuming & peeling the fruit deep enough until the dots are gone would be a waste of such a succulent fruit.

Its more about optimization-problem - linear algebra and analysis - maxing out the resting fruit-mark and still get rid off all the junk ... while spirals make it look awesome as well - and thats proven the best way for use of a linear tool ...
He cut it that way cause it looks cool
