pineapple and mathematics

[BeatlesRock118]

more like pineapple and connect the dots

[tantop]

Where can I purchase those tools?

[agentjucey]

@tantop I know right.

[Schueleraccount]

You can buy it on the night markets in shanghai or everywhere in China.

[AlzAdventures]

where can I buy such knife? is it available in china? or in the UK?

[412356]

Drill that into my mouth!!!

[pochoybilat]

lol too of the funniest top comments ever

[SuperNicolepeace]

the v shape knife looks like a carving wood tool -_-

[YeahItsMilo]

I wonder if that nifty tool he used was made for the sole purpose of peeling pineapples :\

[MrAUFANATIC]

lol that last cut was how a boss cut

[JerryYenful]

@MrAUFANATIC

No, that last cut is not an enterprise level of cutting. You can do it by a simple lathe with stainless steel framework.

See some staff level of pineapple peeling somewhere else. They are not bosses but a staff.

The curve is essential and customers won't wait for too long.

[wha1ever1]

My grandfather can do this just with a knife.

[empresstroy]

those tools are perfect! I will now cut up my pineapple with my stupid north American knife and I assume it's going to take like an hour. oh well. at least i know how the pro's do it.

[JuPp3]

@empresstroy I clean and cut a pineapple like that within a minute with a plain and sturdy american knife. And it would be easyer to eat it too, the way I'd do it. ;)

[adonijah1]

@JuPp3 What's an "American" knife? I don't think I've seen one of those yet.

[JuPp3]

@adonijah1 There's actually no such thing as an American knife. I guess Empresstroy meant a chefs knife. But she used the term North American knife, so I chose to use that term aswell. ;)

[NightMaricB3AST]

@JuPp3 No American knife? Bowie Knife. This debate is done.

[bacaboi]

Vihart explains the mathematics of pineapples. She's a GENIUS. /watch?v=gBxeju8dMho

[MarzErth]

Peeling level: ASIAN!

[Maaaaaaaaaaaaaaartin]

It makes it look cool, especially for tourists. They charge a higher price because of the performance.

[hellafuckyou]

there are also 5 sets of parellell lines and 13 sets of paralell lines. im asuming they cut the pattern of 8 parallell lines because it doesnt waste as much fruit.

[hellafuckyou]

there are 3 sequences of fibbonacci in pineapple. this one is cut by the 8 parallell

[BloodyParanoiaxx]

It looks so pretty owo

[idobrykh]

Крутязямбо!

[pupu562]

2+2 = emc2 LOL

[clomid100]

It's a Fibonacci sequence.

[djteac]

@clomid100 where ?

[uman965]

GREAT!!

[josefpl1]

Cool

[avitanfelix]

looks good after cleaning but alot of wastage

[EsMcJD]

@avitanfelix i agree

a bit of waste

[wizmurat]

wow look at that! nature is amazing!

[arisdages]

you tell us einsten!

[ladyboylizard]

mathematics is behind everything. those dots represent number sequence. following these sequences create beautiful pattern on the pineapple

[addison634]

Then will you peel your heart like that?

[addison634]

It waste alot of pineapple

[The007125]

Nice way to peel a pineapple

I think the lesser loss in this way is math

love your experience man...........

[RandyWelder1]

don't know where he was, but I saw a very similar fruit cart showman peel pineapple the same way with same kind of knives, in Thailand, less waste, and attracted attention of on-lookers, so he sold more fruit,,, the guy I saw was faster though,,, in less than 15seconds he had my fresh pineapple: skinned,de-eyed,hacked n2 bitesize chunks, in abag,ready,and waiting on his pay, I paid and asked, How much to cut up my ex-wife d same way? he looked at his wife, and smiled, "Bring here, I cut, free!"

[nickcool231]

stop at 0:31 ... its bionic commando

[skootb2]

Pkay iGot it!

Its pineapple - dots = good eating

[johnsonttw]

It is fibonacci sequence number in nature.

[Slayer902]

wastes less.



[Cachorrowoofito]

because is pretty and decorative...

[mexifon]

peeling i meant :P



[mexifon]

he obviously a uses the schrodinger's equation in combination with the most modern advanced string theory postulates, actually that chinese guy was a Phd in particle physics, who decided to leave it all and live a more spiritual and down to earth kind of life pealing pineapples. genius!

[puffyclouddd1]

Its so pretty i dont want to eat it

[puffyclouddd1]

I love your pineapple art"

[cherrybuffy]

แกะแบบนี้กุก้อเพิ่งเคยเห็นเองจ­้า - -

หนูมิรุ~~

[missmichelle1997]

What math ??lol

[jewelinthedesert]

Those "black dots" if you were curious what they are called, are the eyes of the pineapple. Idk if they have other names as well. I can't find a mathematical reason, except less pineapple is wasted.

[GridJumping]

Here's the math. It takes a lot longer to care about the question than to not care and enjoy the pineapple.

[maxproxyDotTK]

weil so nunmal am wenigsten Fruchtfleisch weggeschnitten wird? Was für eine Frage -_- Aber das Video gefällt mir^^

[owoowo92]

這樣有點浪費，肉都被刮光了ＱＡＱ

[Slic3R1]

This isn't a mathematical question it's more of a biological one

[TechnoBassUp]

that how he keep most of the fruit ^^

[daloart]

because fibonaci numbers will make that pattern in a pineapple

so it will have the same scale.

not sure lol

[assthemagichat]

math?

there's an app for that.

[VicVicious21]

If ur a man who can explain to me the mathmatical significance behind "peeling" a pineapple, im ready to play student! ;D Oh, love intelligent men <3 :o

[hubbabubbarubbalubba]

It looks pretty, that's all I care about right now. But maybe the dots have something to do with multiplication?

[moewishaw]

the only mathematics is fresh fruit+expertly cut = ££££. you do the math einstein.

[WatsupBroh]

good way to peel! wastes very little of the pineapple.

[jeeen8]

why so much hate. and unnecessary use of pretentious worlds -.-

[GoldenChildBH]

He obviously used the equation (932x - f(w)^e^.0003)Y to peel the pineapple.

[kionay]

one guess as to the pattern of those dots?

i'd bet money it is linked to, if not exactly in reference to the golden ratio and it's ability to be found in nature, conch shells, pinecones, sunflowers, i woulden't be surprised if it was this pattern thats also in pineapples

[dinorahjuarez]

y las matematicas????

[mugsyjeff]

Thanks for this video, I went out & bought a pineapple just so i can do this myself & appreciate the Fibonacci numbers for myself. Plus i'm going to plant the top. thanks again. cheers

[subseeker]

Where could I buy one of those spike removal "knives"? Does it have a name?

[ludwiglaoshi]

@subseeker I bought this knife in Shanghai, but I think you can buy it in every Asiashop. it is a v-shaped knife. But there is no special name for it.

[subseeker]

@ludwiglaoshi Thanks :-) I guess I have to keep looking and pop-in the nearest Asian store.

[MyNameIsUmm]

@ludwiglaoshi I think they meant the 1st knife

[lolalikeswalks]

Fibonacci's Spiral.... cool example.

13 rows vs 8 rows

Good math...

[Ken106]

Damn, my fellow Chinese fruit seller is a pro at peeling pineapples

[Garuda1337]

Wow that's so racist....just because he's Asian you assume he uses math to peel a fucking pineapple.

[Failure2424]

@Garuda1337 best comment ever.

[pitchman2010]

This from the prick that thinks he's Einstein. Please do not reply you are just like your videos.... BORING.

[pitchman2010]

Good video stupid question.

[ludwiglaoshi]

@pitchman2010 There are no stupid questions only stupid answers.

[mlknight14]

@ludwiglaoshi I believe that classifies as a "stupid answer"...

[RuckaInc]

@ludwiglaoshi Oh yes there are. There are some things people should know about this world.

[sasham1984]

@ludwiglaoshi the only stupid queation is the one you do not ask!

[SuperBoatznhoez]

@ludwiglaoshi That was a stupid answer.

[alessioschirru82]

kundalini

you must not buy a knife but lern to cut with a normal knife..it's so simple

[alessioschirru82]

@alessioschirru82 kundalini metod

[bluebaydogg]

actually less waste.. if you cut it down until the black dots dissapare, you lose the pineapple that makes the spiral.

[Povidius]

Nice try, but I'm not doing your math homework for you!

[CasataCooking]

waste of a pineapple!

[bunstuffer]

Quite frankly, the design engineering that went into the tools are much more interesting than your lazy non-expalnation of the trivial mathematics of spirals.

Get a PH. D. and a job in a real University, Ludwig!!

[ludwiglaoshi]

@bunstuffer Oh, you must have a full professorship for mathematics at one of the best University of the Worlds. But it seems that you are yet still a really poor man. I´m so sorry.

[mufceire]

@ludwiglaoshi That was the most vain attempt at trying to appear more superior to another when it comes to intelligence. You try to diminish the capacity of Bunstuffer, by highlighting what you construe to be an inadequate portrayal of opinion or facts. That kind of childish behavior irritates me! Just to be pedantic Ludwig, the correct use of idioms in the latter half of your rather mediocre outburst would actually be, " Universities of the World " and not " University of the Worlds "!!!

[GavLeCul]

hummm maby he pealed it in this way as it has the least wastage of a pineapple (You can try cutting it as many different ways you know how). Take a before and after weight and this will show you that it it wastes the least amount of fruit. also he can cut it without a table as seen so it benefits him in his job as well as the pretty cool design and if you cut in these groves you get perfect slice so there is your answer so hahaha and you go to a university of where ever hahaha lol !!!!!!!!!!!!

[Fings369]

thats just called tourism anyone can cut a pineapple that way

[ludwiglaoshi]

@Fings369

The question is not, who can do this. Tthe question is why do you peel in this way, when you should peel more then 100 pineapple a day.!

[alstraka]

@ludwiglaoshi

1. Tourism it looks pretty

2. waste - most people just cut off enough so that the black dots don't show you loose all of the fruit between the spirals

[Minither]

Those were some awesome tools!

[IMAQTQ8Y]

mathematical answer would be that u would waste less pineapple this way :)

[nuvamusic]

lol.. I thought it was about some fun math game.

This is no brainer, just pure simple spatial/geometric logic.

[vladlovesceltic]

@nuvamusic Never have the words "fun" , "math" and "game" been uttered in the same sentence before, ... are ... are you Jesus ?

[ludwiglaoshi]

@nuvamusic If course it is not a brainer, but it is to think about why the fruitseller do it in this way. You can reason it mathematicall by the Theorem of pythagortas or even more easier by the use of the Triangle unequation.

[nuvamusic]

@ludwiglaoshi lol, Pythagorean Theorem, really? I can't see how that can be applied here. Can u pls explain? Now, I'm very curious :)

[ludwiglaoshi]

@nuvamusic First you assume that the Pineapple looks like a cylinder, than ifyou assume that the blackdots, which are the blommosof the pineapple, are staggerd as a square on the spreadwallof the cylinder, so you have 90°-angles and the diagonal is about sqrt(2)-1= 41% longer than one edge of a square, so you can estimate how long does it takes.

And of course this is only one model.

[Umsack]

Fibonacci BABY! I believe the guy is cutting across one of the 3 arms with 13 spirals. The other 2 arms have 5 and 8 spirals.

[monahan8891]

b/c it maximizes your speed but as well as how much you get from it b/c the dots are closer diagonally then horizontal or vertical so you cut out the bar min. of the good fruit

[ludwiglaoshi]

@monahan8891 Yes your right . But can you guess much faster you will be?

[monahan8891]

@monahan8891 depends on the tools.. ive but it this way but with a reg knife, it was slower but i didnt care now if you have the right tools id say barley faster then just cuting the sides in deep

[takaramatsu]

So cool !!!!

[GD4LBeast]

because its better than the other way.

[ludwiglaoshi]

@GD4LBeast but the question is, why is this way better than the other ways. What do you think?

[zqdz123]

@ludwiglaoshi

this way is the best combination between Maxfruit and Minitime

the best part of pineapple this the edge,the sweetest.However if you cut the black

holes point by point,you need much more time.(some people do this way)

[IMAQTQ8Y]

@ludwiglaoshi like this u would waste less pineapple (the actual fruit :p) :) .. if u have tried peeling a pineapple then u would know what i mean :)

[sarelle500gr]

cool :)

[ramixxx999]

where can a find thats tools?

[yawenalice]

@ramixxx999 you can actually just use a regular big knife. it's just going to be more work :) lol.. this one is like a cheater's pineapple tool kit.
