Feynman 'Fun to Imagine' 3: Rubber Bands

[HelterMcSkelter]

0:16 I love the twinkle in his eye. He just can't contain his amusement with elastic polymer behavior in rubber bands.

[w00td00t]

You know those 2D physics sandboxes? Like phun and such. I just imagine how excited this man would get when he saw some of the things people do with those programs.

Just look up "Phun Gas Law" on youtube and imagine Feynman's reaction to it.

Such a wonderful man. He's pretty much convinced me to dedicate my life to studying physics (I was unsure of whether I should study neurology or physics)

[KaslarProductions]

0:28 You heard it here folks. Chains are kinky. =D

[pyrea17]

i learned about this on the slingshot channel. Amazing when you think about it!

[ftlqed]

I've watched this 20 times, a steel spring only works because its long, it is a rubber band, it only pulls back because it has necrosis of length. Necrosis is do to imobility, imotility, and tactility, just a mess. Then you give him 20-million dollars, wow, your so smart.

[TheKcsmithy]

very interesting video thanks

[jjclassjj]

brilliant video

[MrBrucebracey]

interesting video and very informative

[ArchibaldCoke]

This cooling effect gives me an idea for a rubber band based refrigerator.

[episcophagus]

@ArchibaldCoke Yea! Take a loop and stretch one side and contract the other and make it run over two wheels (one driving and the other breaking)! And no freons leaked into the atmosphere! I wanna have one of those!

[episcophagus]

@episcophagus breaking - brakeing! Of course!

[Willipearse]

Think the Rubberbandits will find this a hot topic. :) The Unabomber was also interested in the physics of Rubber bands, after he heard a lecture by Prof. Zeeman.

[montrey666666]

the fact that selena gomezs' vlog got featured to this lifechangig video, and that it has 60x its' views annoys me and makes me sad at the same time... hope enlightment hits younger generations before it's too late.

[ThaFacka]

I've found out this effect with an airballoon when I was i kid! Now, 20 years later, I have a precise explanation of why it became cooler/hotter...

[Nossucram]

Albert Einstein said:

If you can not explain it simply enough, you dont understand it well enough"

It's not hard to tell that Feynman understand the world well enough!

Thumbs up if you agree :-)

[kristofarkas]

2:20 - made me another person

[AndreBlackScribe]

This should bee the 101 of teaching teaching.

[2eelShmeal]

Just look at how this man lights up when talking about something as seemingly mundane as rubber bands. Who else would be so excited about something so obscure?

When you have a deeper understanding of the world, everyday objects can be filled with wonder. We can marvel at the intricacies of a thing when other people see just a boring item. Science gives us a look into how things REALLY are.

[ken6346]

1:44 oh my god...I used to do this all of the time and felt the same thing, but this bloke actually tried to account for it and did it perfectly. What a man.

[brucecrossan1]

LOL. I thought I was the only one who took rubber bands and stretched them by my lips. :D

[zkennedy80]

Never knew about this man until today. This guy was awesome.

[hectified]

It amazes me; the way this guy is able to simultaneously gush about how complex science is, while presenting it in such a way that it's comprehensible to the average, interested person.

The man was truly a gift to his species.

[xjaskix]

hahah, holy shit, just recently at work i noticed all rubber bands snap after a few months or so if they're holding together a stack of paper, even if no one ever touches them.. and i wondered WHY the hell do they snap like that. well thanks to mr. Feynman here now i think i know why: the damn heat-creating bouncy atoms.

[matsis01]

I noticed this as a child, and never thought anything of it!

[TheGuyWhoToldMeToTel]

Do rubber bands work in a perfect vacuum?

[Rogueek]

@TheGuyWhoToldMeToTel - dQ/dt = k delT

[TheGuyWhoToldMeToTel]

@Rogueek Word.

[prasoonpandey2000]

@TheGuyWhoToldMeToTel of course.they should go on "indefinitely" provided you could just stretch them & then somehow "throw" them in "empty space"

[mawd83]

I wish he was my science teacher in high school. I would have become a scientist instead of working in construction.

[hmspinaforethisisspa]

@mawd83 Please continue to study science in your spare time though! It's all just so WONDERFUL :) all you have to do is start right at the bottom and gently work your way up at your own pace. I did just that myself - my uni course is psychology, but after watching a video of ferrofluid and lamenting that, because of my academic choices, I would never understand the miraculous mechanisms by which such stuff behaved, I thought "To hell with that!" and went and bought a couple GCSE science books.

[hmspinaforethisisspa]

@mawd83 (continued) And I haven't stopped learning about science since. Am now on university-level biology and maths, and A-Level chemistry and physics - and am working at a highly reputable lab 6000 miles away from where I started. Please learn about science :) it's never too late to start - and there's so much joyous wonder to be discovered...

[Dimajo]

@mawd83 You can't help but become optimistic when you are listening to mr. Feynman so perhaps i sound somewhat childish, but is it really too late for you to become a scientist? Yes seven years is alot! perhaps you are too "old" ? you tell me, but then i suggest a science teacher be as inspirering as feynman, or perhaps even better. Is there anything more important than doing what makes you smile? But then again you can discard of all of this perhaps it is just a biproduct of feynmans enthusiasm

[crappymeal]

could i heat a metal pipe by raping it in stretched rubber bands?

If I have a sealed box with walls made of stretched rubber bands will the area inside be hotter, cooler or neither?

[skydome29]

I saw rubber bands and thought how is Richard "Mcgyver" Feynman going to explain his way through this one.

[nhmllr725]

I did the thing with the rubber bands on my lip, and it works!

[zer0dahero]

i wished he had mentioned that the energy those "giggling" molecules have come from the surrounding air. Their perpetual motion is fuled by the ambient heat. Thats why if you freeze a rubber band, it may break if you try to stetch it as if when it was not frozen.

[Master8laster]

@zer0dahero I guess you already know though.

[gatoradeee]

yes the world is indeed "jiggling" so long as it has a temperature above absolute zero. in which case the only things "jiggling" are the electromagnetic waves of the universe. 

[Vennificus]

@gatoradeee what about zero-point energy from an electron?

[DogBoots77]

Who is the other guy who didn't like this video!? I mean - the first's got to be Adolf, but who the hell pressed that button the second time? Weird.

[majst0r]

@DogBoots77 Well... if the first one was Adolf, the second one has to be Hirohito. :D

[inphrased]

Who else would find rubber bands so fascinating? I love this guy, not everyday you can see a man with such passion.

[fyeJack]

This video makes me sad i don't have a rubber band on hand. I want to try this out.

[projectcedric]

Funny, I wonder what does the sun or the galaxy thinks?

"Planets and societies are a dynamic mess of jiggling humans. If you magnify it right, you can hardly see anything anymore because everyone is jiggling in their own patterns (human lives). Its lucky that we have such a large view of everything that we can see them as planets and societies without having to worry about the pathetic lives of those little people all the time."

[Arcrer]

Richard Feynman, a man who thinks rubber bands are fascinating, I love it!!!

[devotedpupa]

Why is selena gomez a features video here?

[seemyjohn]

@devotedpupa

Probably because of the tag "jiggling."

[Ccolebrooked]

SO. AWESOME.

[spartacandream]

Feynman's got such great enthusiasm and explains it so well!! Our universe is one strange mess of jiggly atoms.

[Koujinkamu]

You're a fine man, Richard.

That's right. I said it.

[WoodstockHippie1969]

ChristopherJSykes Rocks !!!

[SporeZoo]

"The world is a dynamic mess of jiggling things if you look at it right"....this man is brilliant !

[pdpbigbang]

my balls are jiggling too

[jmaytum]

Thank you for sharing this. What an amazing individual with an incredible ability to explain. What a shame he has passed on.

[anjundoobies89]

@ enhanzable , sad how you call michio kaku a "retarted dumbfuck". to even use that term to describe someone who is so visionary and knowledgable really shows who the "retarted dumfuck" is. how many years of school does it take to become a "retarted dumbfuck"? as many as uve been in school?

[lytrigian]

What's wonderful about Feynman is that when he says something like "If you heat a rubber band, it'll pull more strongly" you know that he's *actually done the experiment at some point* no matter how simple it seems to be.

I think that's one reason he's was so able to put physics ideas in simple, everyday terms: because he always remembered the questions and observations that impelled him into physics in the first place, and he never lost his fascination with them.

[enHanzable]

It's tragic we don't have people like Feynman around anymore. The job of making physics interesting for the general population is left in the hands of retarded dumbfucks like Michio Kaku, who does nothing but getting cocaine-high on the publicity of lies, ridiculous exaggerations and incoherent, self-contradicting technological fantasies, to the point of delusions of grandeur. If only someone in the field would speak out about this, the coming generation takes him seriously because of his Ph.D.

[ravinprophin]

@enHanzable Lot's do, even students of his. But he argues that String theory is the next paradigm shift in science and the viewing of our universe. I admit String field theory and his goal to have a Theory of Everything is pretty jarring, however he doesn't pull this stuff out of his ass and he even said that the Theory of Everything can also be a Theory of Nothing and we won't know until we solve the equation that even Einstein was trying to solve before he died.

[enHanzable]

@ravin. lol you should try talking to his students some time, they call him a self-centered, moody asshole wasting time forcing them to watch all his broadcasts/interviews and buy his books which are outside the curriculum. "even einstein"? you realize einstein wasted the latter HALF of his life fighting against science and progress (quantum mechanics)? by the time of his death, nobody took him seriously except the ignorant masses who bought into whatever the media wanted to present him as.

[ravinprophin]

Were you a student of his? What science did you study or major? What are your views of the cosmos?

I personally have a problem whenever someone tries to predict what will happen in the future; too many variables involved to get it accurate. Red flags also come up when I hear him lecture about an inch-long Theory that would explain everything in the Universe and M-Universe.

In short I may not agree with Michio Kaku but I still respect him in the same way Sergei Eisenstein respected D.W. Griffith.

[enHanzable]

@ravin. kaku is so far removed from reality he only makes sense to that same crowd. they think not understanding him is part of what makes him so unbelievably awesome. they just assume that at least he himself is in total control of facts and the future of science, because he has the same haircut as einstein. he's a braindead poser who needs to be put out of his misery.

[Paullove89]

@enHanzable Couldn't agree more. Kaku's a feckin' nobhead. Anyone see him in that The Secret video?

[NoSz4]

well put enhanzable

[biorobotmachine]

TROLL

[Aletheophile]

Was this interview done before or after the Challenger inquiry?

[Aletheophile]

Oh, just saw the date in the description, never mind.

[brenthoser99]

hhahahahhaha. I love at 1:09 you hear one of their small intestine grumble. hahahhaha

[CornCob6000]

Hahaha! Well spotted!

[yorktown99]

And in three years he demonstrated how super-cooling rubber takes all the stretch out of it: the chilled O-rings on the Space Shuttle had no elasticity left to contain the fuel and prevent an explosion.

[bloggycreek]

Feinman is the man! Who ever thought rubber bands were so interesting?

[rjq731]

I've done this rubberband thing on the lips without ever knowing the chemisty/physics that goes into it. Wow! i love this man!!

[HumanStrategy]

This man is a badass. Too bad most of us didn't have a chance to have a little chat with him.

[slackologist]

"the world is a dynamic mess of jiggling things" :-)

[darthzydar]

String theory, in a nutshell.

[yorktown99]

No, he's not talking about string theory, which attempts to describe the structure on tiny quarks and bosons, but of individual atoms and molecules.

[darthzydar]

And yet, String Theory is but one abstraction away from what he's saying. What is String Theory, really but "a dynamic mess of jiggling things", (a muti-dimensional mess at that), that twist and turn and vibrate to form the fundamental particles and indeed, the world? :)

[Craggles17]

Don't make statements you clearly haven't researched, people might believe you.

[mrpossibilities]

Yes, that pretty much sums it up, my friend! :)

[yorktown99]

No, you are missing the point. Neither is an abstraction, but an explanation of what is really going on. The "dynamic mess of jiggling things" he talks about has absolutely nothing in common with any aspect of string theory, which is actually two or three layers in magnitude smaller than normal atoms.

[darthzydar]

Sigh. Let me explain myself here. He is certainly not talking about String Theory. I merely pointed out that the idea of the world being a "dynamic mess of jiggling things" could have well been one of those that *led* to String Theory being formulated since it is, in essence vibrating strings combining to form the particles.

So yes, he is not directly or indirectly talking about String theory. The statement I made was in hindsight and describes a simplistic String Theory rather well. Allegory.

[dan314159]

strings are a billion times smaller than atoms!

[spartacandream]

@slackologist Amazing thought =)

[pollocybertronx]

what he says in the end... i think about things as little atoms a lot.

[thecamlayton]

Me too. Consider the Buddhist notion of "emptiness".

[mrqwantz]

"The world is a dynamic mess of jiggling things, if you look at it right"

Oh Mr. Feynman, I love you man.

[LeoLeoni13]

@mrqwantz Dr. Feynman

[stevelee777]

This reminds me of the Challenger disaster and the rubber 'o' ring. If he'd had said more directly what happens to a rubber band at freezing temperatures it would have been kind of freaky... maybe...

[DonQuichotteLiberia]

Thank you very much for uploading, this is awesome.

[navghtivs]

Wow, I found a piece of rubber band and tried it immediately, it is true, and I never knew this, fascinating.

Feynman is such a great scientist, great teacher and great mind.

[t0kt0k]

Brilliant!

[francescaemc2]

Dr. Feynman... please!!! What's this kinky stuff about rubber bands?

Oh, I love you, I always have.

Thank you for every word and the amount of pleasure you have brought me. "It's lucky we have such a large-scale view of everything."

[Faraday128]

Bei tempi quando le ragazze si innamoravano dei calciatori e dei tronisti. Adesso si innamorano di premi nobel per la fisica (oltretutto un pò morti). Chissà dove andremo a finire...

[francescaemc2]

LOL. e chi non si innamora di Feynman. Ma hai ragione.. O meglio, Ha ragione: quando avevo 11 anni mi sono innamorata di Albert Einstein.

Gli uomini si innamorano spesso di donne bellissime e scheme. Che male c'e'. Io ho un debbole per un intelligenza folle. E' morto, d'accordo, ma se mi innamorassi di, mettiamo, Johnny Depp, non sarebbe piu disponibile per me. Tante belle cose e si vedra' dove si va a finire!(non sono tipica).

ciao, francesca
