Gomboc: How Turtles Self-Right

[acsodalatosmandarin]

Richtige Aussprache:: [gömbötz] und nicht [gömbök]

[felsspat]

Here is a video from QI that explains it in english:

watch?v=XCAg5_vH

[parsifal7301]

Wrong pronounciation. It is not Gömbök, but you have to say something like: "gömböts". "C" in Hungarian is not "K", but just like "TS" or "DS" or normal german "C". (regards from Hungary)

[MrMundy107]

This reminds me of the penis sculpture from A Clockwork Orange.

WHAT SORCERY IS THIS?!

[markfakelastname]

@TheBehattedOne Thumbs up for the Futurama reference. It took me a second to place the quote. Well done, Behatted One.

Did anyone else almost crap themseleves when he started talking?

[BoltonASD]

the inventor appeared on QI - it has no practical application and Rich Hall asks him "Do you feel like you've wasted your life?" Ha ha

[Floorsquid]

Such a nauseating language, it just sounds like talking in reverse. Its garbage

[smuffinator]

@Floorsquid du bist ein sheisskopf

[lillla]

das wird als "gömböz" ausgesprochen:D 

[n3bulous]

bruno?

при чём тут черепахи?

[FFFUUUCCCKKKEEEDDD]

So what we have here is an ostentatious paperweight ?

First Attila then the rubiks cube and now this , the Hungarians sure are on a roll.

[phantom9195]

hahaha keep replaying it at around 0:48 im sure he ses "hmm shit"

[Armistice023]

Schildkröte. Literally "Shielded toad"

And he did say breakdancer. Many languages use English words or English equivilents. Telephone, telefon, telefono.  Computer, komputer...

[tholfeld1]

hahahah breakdancer

[xdegenerate18]

The first thing the guy says is "shit curtain"

[chillz27]

@xdegenerate18 hahhaha i lol'd

[Ado501]

@xdegenerate18 Shit Curtain is German for Turtle :)

[TheKriszman]

hungaryhungaryhungary! best!

[rjr1967]

Why does he say "gömbök" rather than pronouncing the "ts" at the end? Shouldn't be difficult for a German speaker. Is there an international pronunciation of this word?

[Bukowszky]

sildkrőt gömbök :)

[TheMasenko]

túró gombóc. Ilyet már öreganyám is csinált, nem mai találmány ez :D Van szilvás is.

[cnmarine2006]

didn't understand a word cept in the end it said something "breakdancer."

[IstOne1989]

@cnmarine2006



ROFLMAO

[henes13]

The original name is "gömböc". It's a hungarian invention.

[dzeruel]

its not gömbök or gomboc you pornounce it as "goemboets"

[lastheroli]

yes... gömböc is the right name

[lokky7778]

Издеваются над черепашками...

[SJGster]

To the idiots who think that this thing keeps moving infinitely: It does not. There is only one "right way up" for it, but once it reaches that point, it stops moving. (Well, there's another orientation it could stay on, but it's like balancing a coin on its edge)

[TRAXXAS59]

@SJGster ty. i thought this was what this shape was but couldnt really find anything on it.

[fakeaccount663]

@SJGster

no it only has one way up but if made inacuratly there is a chance you can set it at another orintation. if it is made 100,000,000 of a millimeter in any wrong direction then there is a chance it would stant in another orintation thats how accurate it has to be

[FadoDeo4444]

@SJGster mathematically; this keeps moving infinitely, just like a ball never really stops bouncing.

[rvyyn]

@FadoDeo4444 What the are you talking about? Balls stop bouncing "mathematically" as well. What you're talking about is disregarding friction, and that's not the point of this. The point of this is that it always flips to one side without manipulating the center of mass (i.e. using the same material throughout the entire object).

[FadoDeo4444]

@rvyyn actually; i went back and researched a bit and found that friction is without consequence in what I was talking about. Mathematically, a ball will bounce an infinite amount of times; with or without friction. But; you are right, this isn't about the "infinite" movement of this shape... so this conversation is therefore also without consequence... just.. dust in the wind.

[FadoDeo4444]

@rvyyn On the actual meaning of "mathematically". You are speaking about the physical world. What happens is the ball indeed stops bouncing, but it does so after having bounced an infinite amount of times. It bounces an infinite amount of times in a finite amount of time. It's the whole zeno's paradox in a different situation; in which mathematics never allow the ball to ever lose all it's energy until reaching it's full graphical asymptote ( total vertical distance).

[rvyyn]

@FadoDeo4444 No that's not true. What you mean to say is that it is possible to simplify our physical reality using INCORRECT mathematical models (and completely disregarding quantum mechanics) and construct a ball that bounces infinitely. But that's a completely pointless statement as it is "mathematically" possible to almost anything. Zeno was a philosopher, not a scientist, without access to quantum mechanics. And he had many paradoxes, not just one, and they are all based on ROUGH estimates.

[gn3xu5]

I like Gömböcs

[dzeruel]

@gn3xu5 not even Gömböcs

[batchint]

the ultimate spin-off will produce a billion a second

[xVaultx]

Assuming it never stops moving... but it does stop.

[Joker69010]

WHAT DOES IT DO!!

[andrew19891019]

if you put that thing on a plane surface, it never stops moving;) a hungarian invention.. btw i'm hungarian:)

[cykolink]

It's not that it never stops moving, its that it rights itself from any position. It has only 2 equilibrium points and so from any position will tend to the stable 'upright' one.

[andrew19891019]

yeah but still.. it never stops moving.. (does it? xD)

[addmoreice]

it's a shape that has one stable point and one semi-stable point (think tip of a pen) it will always travel towards the stable point..but since it only has ONE stable point it rotates rocks and rolls for a long time till it gets there.

[Dontbustthecrust]

yeah you know what else self rights itself? a fucking baseball and it only cost me $1.00.

[Dontbustthecrust]

I know perfectly well what I'm talking about. The point is, is that I'm not getting a boner or spending hundreds of dollars to have a math equation to self right itself. If I needed to have fun with an overpriced odd shape  I'd invite your mother, the whore over again and play with her tits.

[Luhv2xlr8]

they sell these little pieces of plastic for like 1000 dollars.

[Ohfishyfishyfish]

I swear he said 'breakdancer' at the end.

[leeopard]

he said that some turtles with flatter (so non gömböc similar) shells used theyre necks to get off theyre backs... and that they took some crazy pictures and thats how the turtles ended up being awesome breakdancers..

:)

[Arxon20]

@Ohfishyfishyfish yes ^^

[Patrick45127]

@Ohfishyfishyfish The reporter said "some turtles have been turned into breakdancers"!

[93JonnyM]

@Ohfishyfishyfish He did! :P

That was part of a German report and what the guy says is something like: "And that is how a ,normally known as lazy, turtle becomes a breakdancer"

;)

[Centerman2k]

@Ohfishyfishyfish yep he said "breakdancer"

[BitPit]

@Ohfishyfishyfish he did. and?

[shadewizard]

@Ohfishyfishyfish

i can confirm that. he speaks german and he said it at the end.

[776locust]

@Ohfishyfishyfish

He did. He says

"From clumsy/cumbersome turtles come breakdancers."

[akoolah]

@Ohfishyfishyfish: he actually did. he said something like:. The turtles with flat shells used their necks to get on their feet. The scientist managed to shoot spectacular pictures of that. That way clumsy turtles became breakdancers.

[falsinar]

@Ohfishyfishyfish

Probably because he said that

[DoubleReeds]

@Ohfishyfishyfish he did.....

[thinkadrian]

the title really should be in German, since noone who don't speak that language would understand this video anyway...

[Pattoe]

Its hungarian, not German.. And its merely saying that turtles have the same shape as a gomboc, which is a very intricately engineered object using very advanced mathamatic equations to make it self right no matter what position you put it in.. Unlike some self-rightable objects, it is not weighted in any way.

:-)

[GivenWillingly]

it might be a hungarian idea but the video is german.

[Pattoe]

Ooooh, Sorry, I just assumed it would be in hungarian, My speakers arnt on.

Thanks for correction :)

[Grunbeldodd]

HELP!

[bulko23]

ЧЕРЕПАХИ РУЛЯТ ВСЕМ МИРОМ !!!

[brumanima]

és ezt mire fogják használni? :D

[dopxorbit]

Pl. arra, hogy feldugjuk a seggedbe és megnézzük mi történik.

[PIPIPISTA]

dopxorbit: te nagyon hulye vagy,de ez nagy volt :))! (Bocs a hulyeert) Epp ittam vmit es miattad rakoptem a monitorra.....

[gombost]

A lényeg az, hogy még 1995-ben egy orosz matematikus megfogalmazott egy sejtést, mely szerint létezik olyan homogén test négynél kevesebb egyensúlyi ponttal. A gömböcnek kettő van, egy instabil és egy stabil. Ezzel bizonyítottak egy 11 éves sejtést. Dióhéjban ennyi, gyakorlati haszna egyelőre nincs.

[berakdata]

nagyszerű! remek újabb magyar találmány!

but it's not gömböK, try to spell gömbötz.

[soniazpapp]

Disegn by God discovered by the hun

[brumanima]

try to spell as gömöts" in the end and not gömböck

[brumanima]

ebben mi a nagy cucc? i think i can ask hungarian, cos the name is hun too :) anyway

what is the hilarious in this invention?

[springy120453]

A "Weebil" can't be knocked over either, and has a much simpler shape!

[jedigeek93]

but Weebils are weighted at the bottom this has an average density

[rustyhookj]

only word i caught was breakdancer right at the end,

[BenceRAP]

it'S GÖMBÖC, not gömböK

[BenceRAP]

hungarian invention :)

we did it

[jesusestebangomez]

Me ha gustado. Una vez más el ser humano imita a la naturaleza. En ella tenemos que basar siempre nuestra inspiración para innovar.

[to1m]

un önning brlurrrrrrrrrrrrhhhhhhhhhhg

[gelazso]

Richtig ausgesprochen!"GÖMBÖZ"

[gelazso]

Ungarn!!!

[cazadorhotsex]

El Gomboc (en español "esfera"), un invento húngaro que ha sido el resultado de una larga búsqueda matemática. Se trata de una pieza redonda realizada en un transparente material sintético con suaves curvas, y sólo tiene una vía para balancearse coordinada rigurosamente con la Madre Naturaleza. El Gomboc es un cuerpo tridimensional homogéneo con solo un punto estable y solo un punto inestable de equilibrio.

[sftubing]

nos,,, amúgy elvileg ezt harci járművekre akarnák használni... egy tank mely mindig talpra áll...

[Xezs]

Ezt honnan veszed? Tudsz forrást megjelölni? A gömböc sík terepen nagyon szépen beáll egyensúlyi helyzetbe, na de tudjuk hogy a harckocsikat milyen terepre tervezik. Nem beszélve arról, hogy ha egy harckocsi felborul, ott már régen nagy baj van. Szerintem ez hülyeség, de ha van vmi forrás, szívesen átböngészem.

[kiralykristof]

Értem, hogy homogén, meg a súlypontokat is értem, de mi a ferde f@8zra jó?

[laci6666]

Gyakorlati haszna egyelőre nincs. Egy híres matematikus sejtését bizonyították be, miszerint létezik ilyen objektum, azzal, hogy Domokos Gábor és Várkonyi Péter megalkotta.

[kiralykristof]

Köszönöm az info-t, ezt sejtettem is... Le a kalappal előttük, nem fikázni akarom, nagyszerű, hogy ilyen tökéletes dolgokat alkot az ember, meg nagyon érdekes is... Már utánanéztem több helyen is, hogy mi is ez a gömböc.

[b4rn1k4]

valami arnoldnak hívják és orosz... a matematikus

[grandexandi]

hahahaha the only thing i understood was "break dancer" at the end

[laughingaussie90]

Hahahaha, yeah im exactly the same

[sirjection]

But the Earth isn't a flat surface! :)

There are probably other evolutionary constraints at work, like resistance to crunching and bashing, so we can't expect the convergence to be exact, anyway. And a turtle doesn't have uniform density.

[robtran]

Very interesting video. The experiment with the shapes was instructional.
