Feynman 'Fun to Imagine' 1: Jiggling Atoms

[EstaPhone]

His "Los Alamos from Below" lecture is great, too!

[busplunger]

He once described the movement of a swan's neck in a way that was analogous to what we now know as nanotechnology.Blew my mind!

[TheAlexanderApollo]

Puts a smile on my face :D

[moonrockguy]

Feynman is why i studied physics at university because I read his lectures on physics at high school. He had a way of explaining things that made it understandable. Now I'm a high school teacher. Every now and again I go back to Feynman for advice in how to explain things to children. I wish I could have met him, but i think I would have bored him

[g00hz]

Love him :)

[tonyrosam]

I like how the video is old and it looks like everything is jiggling :) Kind of helps get the point accross

[akshatj42]

"It's very hard to imagine all the crazy things, that things really are like" :)

[mcwaffles2003]

i listen to a playlist of this or episodes of cosmos when i go to sleep, its amazing to fall asleep thinking about the mechanism which constructs the universe, the great and awesome machine of cause and effect.

[jaredngarrett]

Holy carp. That's the same chair that my in-laws have. Also, Feynman won every moment he lived.

[eahazell]

If my science teachers were this enthusiastic I may have done better in science

[cpk9999]

3:50-4:10 lmfao so hard

[Roffe192]

Movement=Temprature?.. will a glowing pice of steel with keep it's warmth if it's in vacum with 0 gravity i mean there is nothing stopping them unless they bounce into eatch other?.. well if they do bounce woldn't a pool of water freeze solid if it remained absolutly still for a long period of time as the molicules then wold have even eatchother out and finaly stoped? Right?

[cixelsyD1988]

@Roffe192 Movement = temperature. A glowing piece of steel however loses some of its "jiggling" because it irradiates photons (light) in the form of infared radiation (heat). A pool doesn't randomly freeze solid over time because it takes in photons in the form of heat energy from the sun and transfers its jiggling to the sides of the pool etc. When atoms stop "jiggling" it doesn't "cause" things to freeze, it is the definition of freezing.

[VanostranIV]

He makes physics seem a little aggressive and almost dirty. I like his faces.

[imashelchazona]

the way he conveys his message gives me shivers. so brilliant

[Silpher9]

They Should clone him

[yeahfree]

Im so glad too :-/)))

[Fallnetthinn]

im so glad i found this via the ama of neil degrasse tyson on reddit :D

[StoddCOD4]

Is mind is just like mine, everytime I do something I wonder what's behind the action, the molecules, why is it like that? So amazing...

[DNYAP]

I am so glad I read about the mentioning of Feynman in a Khan Academy video - Amazing! Just 7 minutes of a video made a lifetime change! Love the way he explains thing :)

[xiwang314]

@marathonjapanのフォローをよろしくお願いします­。

[HayateV3]

I love this guy, if i had seen him sooner, i wouldve wanted to become a physicist! Just look at 4:00 and watch how excitedly he speaks of the material. This is obviously a man who loves what he does. He has all the qualities of a great teacher

[HellnoElmomo]

He seems sexually frustrated...

[me835]

@HellnoElmomo read his memoir; this man was good at getting tail

[ldog1991]

@me835 Because you just need to ask them.

[busplunger]

@me835 make sure they'll sleep with you later before buying em' drinks! otherwise get your money back!

[acr08807]

@HellnoElmomo He was quite the ladies man. I doubt he was frustrated.

[Mrtheunnameable]

He is a perfect human being.

[Gafaton]

I could listen to him talk 24/7/365.

[ThePirhomaniac]

@Gafaton That must be one shitty day every leap year.

[Aezandar42]

@Gafaton Soooo.... you couldn't listen to him talk on Leap Years?

[AvidAstronomer]

@Gafaton That should be 24/7/52 but yes I agree.

[Shuffle2dMax]

@Gafaton I'd listen to him 24/7/4/12 or 24/365. Had to say it.

[lusteraliaszero]

@Shuffle2dMax I'd listen to him 365.2564days/year

[Shuffle2dMax]

@lusteraliaszero Not bad, but I still have the argument since this is youtube and you have to round numbers for the general audience.

Mine wasn't a mistake, it was just a simplification, a step ahead of your answer.

[lusteraliaszero]

@Shuffle2dMax Curses, You win this time, but this isn't over

[lfcharette]

explain fundamental concepts of physics in common language

make face of uncontrollable happiness :)

[superdanu]

what a wonderful lecturer!!!!!

[Scratchyjam]

0:30 Ahh, there it is!

[hameed]

Oh I'm used to balls bouncing

[ilytopy]

4:28, please do.

[Geebsee]

Sagan and Feynman.. Both had to go and get themselves killed before they were 70.. Fucking dicks

[GortonMichael]

@Geebsee What the hell? Feynman died of two different cancers. Do you think he wanted to die?

Same with Sagan, he died of pneumonia.

[Geebsee]

@GortonMichael

Lol, well someone missed the point entirely...

[GortonMichael]

@Geebsee Someone else made an idiotic comment.

[TheKturner05]

@Geebsee what point? that your a fucking imbecile?

[Geebsee]

@TheKturner05

Imbecile, perhaps, but an imbecile that knows your from you're, unlike an imbecile such as yourself. Yes, if you're retorting to ad hominem, I retort to pedantic poo-flinging.

[TheKturner05]

@Geebsee did you not understand what I meant? This is youtube not Life magazine, grammar is not important. The meaning of your statements however are. Its clear to me your a troll.

[Geebsee]

@TheKturner05

Sigh. You don't realise that name-calling is bad juju? It's about as worthless as being a pedantic prick, but you apparently thought I was being serious in pointing out your grammatical short-comings (although I think I made it quite clear that it was an attempt to undermine your ad hominem attack). Now, the meaning of my post, to clear it up, was a satirical way of saying they died before their time. Please find something more useful to do than picking fights on YouTube.

[Sektor14g]

It's so... nice to see someone enjoy their work and light up as much as Feynman did. If people put even 1/100th of the dedication, pride, and feeling that this man put into his field then we wouldn't have colossal fuck ups all the time in work forces around the world. Such an inspiration to just see someone enjoy their life.

[1971mgb]

The whole series should be required viewing in every school. Even Grad school.

[Androly]

I love to spread my jiggle!!

[nikanj]

3:02 That's what she said.

Sorry couldn't help it even though I'm a great admirer of Feynman.

[tsoogii]

these videos are addicting :P

[Bullroarrer]

@bartekqitara De Niro had a baby with Walken.

[yurismir1]

@Bullroarrer Well, both Walken and DeNiro are from New York City, so it's probably just the accent you're hearing.

[NevermoreJones]

Wow, I knew about heat being kinetic energy, but I never realized balls bouncing on the floor transferred it's energy to the GROUND. It makes sense ^_^

[rohitaudipudi]

7 people are an accident...

[TheRtjhe]

his happiness is so apparent.... and transfers to all around.... his jiggling atoms sure jiggles all around him :))

[racastilho]

Hahaha, seven people disliked this video! This is the funniest joke I heard lately!

[prasoonpandey2000]

WOW



[ahmeadors1]

We need christopher walken to remake these.

[joshua2443]

@ahmeadors1 So weird I was thinking the exact same thing.

[ahmeadors1]

@joshua2443 it would take 2 hours for him to articulate all of it, but hey i would watch it...and think about my father's wrist watch...

[xyling]

@tastedabjful OK, makes sense! Thanks!

[xyling]

Wait wait wait. Energy is not created or lost...so you heat up a hot sphere of metal and drop into a perfect space vacuum, with no contact with any other objects, would the sphere retain its heat, it's jiggling? Where would the heat energy go if it was not in contact with anything else?

[prasoonpandey2000]

@xyling how can you "heat" the metal sphere without "contact with any other objects"?????

[timeweston]

I love the internet.

[Wheelsgr]

@timeweston well said.

[garvary159]

sounds like De Niro looks like Stings dad...lol

[VERGIS92]

He says he doesn't like honors and prizes, but he was quick to go to Sweden and collect his nobel prize, and one million $.

[onedaydude]

@VERGIS92 wouldnt you?

[ldog1991]

@VERGIS92 Actually, at first he wanted to refuse, but accepting was much easier and less attracting for reporters and such, so he went with it.

[paulandmo2007]

I haven't even read below yet but GUARANTEED 7 people are fundamentalist christians!! LOL

[opmike343]

All of my science classes were amazingly interesting...up until the pop quiz or exam at the end.

[InfinityDz]

This guy is like my father

[mscpeter]

4:13 - 4:30 is unreal.

[paulandmo2007]

@mscpeter uuhhh... how do you figure? he's voicing his own opinion about himself? Unless you have powers to establish how another individual is thinking and feeling? In which case I recommend you sell your wares.. Human Lie Detector testing.. would make you MILLIONS... I in fact feel the same way he does.. I suppose you will say that is unreal too?

[mscpeter]

@paulandmo2007 relax dude. i meant unreal as: amazing.

[alquiora]

"There's no teacher when they ask you question at the end... otherwise it's a horrible subject!"

True. Science is fun and that teachers make it horrible!

[kenphanacean]

In a perfect world, guys like Feynman would have their own talkshows. 

[BlameRepublicans]

If they ever make a movie about him they should hire Harvey Kitel to play him as an older man

[mike18at]

I'd wager the 7 people who pushed "no" did so by mistake. Out of 1700 people there have to be SOME who click in the wrong (the no) button.

And yes Mr. Feynman, it is "Fun to Imagine", thanks for the great lectures!

[swagnik9]

@MegaBEANER1000 I dont 'THINK' I understand physics. I 'KNOW' I understand physics. So by your logic, I am not an idiot.

[fekkapa]

he forgot about phosphors

[DBijlsma]

Seriously, I love the enthousiasm with which he's telling about his..passion if you will.

[striuncekf]

am i the only one worrying about the atoms that get stuck in the bicycle tires and lose their freedom?

[rivestalex]

What a pleasantand intelligent human being :)

[mobcat40]

My favorite scientist Feynman is the man. Also I second Robert DeNiro losing some weight and playing him.

[MuteHelperComments]

He's like a little excited child. Fuck Jesus, give me Feynman.

[paulandmo2007]

@MuteHelperComments hee hee hee.....

[LibertasLoquendi]

This once again proves that it is imagination that distinguishes the ordinary man from the genius. After all, only those who have imagination can invent.

[bobsacamano1]

what did he mean right at the end? something about teaching and asking questions. . . ???

[lazurm]

@bobsacamano1 He simply meant that learning about nature should be done with an attitude of having fun with it, not to take it too seriously, implying that, to do otherwise, would make it a "horrible subject".

[jagara1]

What a fantastic way of presenting physics.

I was not allowed to take physics at school - because my teacher was so boring that he did not inspire me to learn anything...

[bartekgitara]

Close your eyes - De Niro?

[Aesthir]

@bartekgitara rube

[yurismir1]

@bartekgitara Well they both have New York City accents, but so do millions of other people. That's the only similarity I hear.

[johnmacward]

@bartekgitara Howard Zinn actually.

[markhollandmd]

The second greatest human mind in all of history.

[cmd2tuts]

@markhollandmd Indeed.

[lazurm]

@markhollandmd Let's not forget those nameless souls who invented the wheel, language, cooking food, shelter, and the first tool.

[IloveYOUviruses]

simple mental models: the key to intelligence

[TheKenTerry]

This guy is awesome, he literally gets giddy when he talks about science.

[savagecabage]

no why would i be talking about that. i was on about what did jesus do for us really, and ive heard it all, died for our sins yada yada.

[savagecabage]

Jesus has a youtube account and he is jealous that Feyman knows more about jiggly atoms than he does. (ahem @guyNbluejeans)

[paulandmo2007]

@savagecabage LOL!!!

[polpotsdog]

beep bop boop.

[m1111jan]

If they ever make a movie about him, he should be played by Robbin Williams.

[nickleus1977]

@m1111jan hilarious! so true =)

[1965Richie]

I think I know how a refridgerator works now. It's like a big bicycle pump.

[edga69]

7:00 so true.

[chizhr]

I think the explanation about pump was a bit wrong, it heats up not because you hit atoms with a plunger (while moving), but because when you decrease volume drastically with the same amount of atoms, it makes them hit the walls of the pump more frequently. The effect that he describes is very small, since the average squared V of atoms is about 500m\s (for the temperature 68F )the extra speed that you give to atoms is nearly 1-2m\s thus the effect is very small. Am I wrong ???

[ozipiper]

@chizhr Feynman's explanation is right. The temperature doesn't depend on how frequently the particles hit the wall of a container, but is a measure of their average kinetic energy. If the average speed of the particles is around 500 m/s, how many collisions would you expect an average particle to collide with the pump piston as it moves inwards? If on each collision, it gets even a small speed boost the net effect will be quite big...

[rahimShah]

I wish I was smart like Mr Feynman, I could live any where in the world and still be happy :(

[lazurm]

@rahimShah To try to be as smart as Feynman, you have to, first, learn that happiness is an attitude you can take with you anywhere and regardless of your smarts because happiness can come with the excitement one feels through persual of passion, motivated by curiosity and love. First, know yourself. Second, love who you are. Third, be passionate for your wonderments, but have wonder for all that is.

[gweedoz84]

@lazurm

I agree completely, but we also should keep in mind that some people are 'predisposed' to be happy by not having had any traumas, stress in childhood, stress circulating in the mum while a fetus, social stress, disabilities, psychological stress, alienation etc. To tell people 'you should be happy' is a bit of offensive for those who may never ever know what happy means, or have limited allotments of happiness for whatever reason.

[lazurm]

@gweedoz84 Actually, your quote is a misquote since I never wrote that "you should be happy". I'm not sure if some, though, are (as you stated) "predisposed to be happy", nor have I met or know of anyone that hadn't experienced any trauma, stress in childhood, etc. And I'd bet that the great majority of people understand what happy means. I was, though, addressing what Feynman observed by his comments on passion, curiosity and wonderment.

[paulandmo2007]

@lazurm Brilliant. Could not have said it better. Namaste _/!\_

[beforever]

@lazurm pursuit.

[elmstfreddie]

@lazurm Fourth, you can't be as smart as Feynman if you didn't notice he had two firsts :(

[lazurm]

@elmstfreddie Golly...you're right! But, nonetheless, I'll be the FIRST to admit I'm not nearly as smart as Mr. Feynman was. :)

[techpops]

@lazurm I think its more accurate to say, first, have an awesome childhood with a father who encourages you at every turn to learn about the world and make it all a fun game at the same time. Feynman is simply taking what his father taught him as a kid and expanding on it with ever more complex ideas as his knowledge increases but essentially he's still that kid having fun.

[hnbsniper]

@lazurm Youtube commentor, Y U SO WISE?

[akbarblanchet]

@hnbsniper lol, i pictured "Y U NO" guy

[amiyaiitkgp]

Feynman has such a way of explaining things....its mesmerizing....Feynman's lectures must be compulsory at schools world over.

[justinllalor]

At least 6 people are retarded in this world.

[SlipAllCityToy]

@justinllalor

You lose,

Love needs more upholding than hate and fear, because at the current world its so easy to be sad and angry and negative all the time, that's the reason you are focusing on the 6 people that disliked this video rather than the 1,297 people who liked the video.

[paulandmo2007]

@SlipAllCityToy and yet your first two words are negative.. Hmmmm...

[SlipAllCityToy]

@paulandmo2007

I wasn't trying to imply that he's a loser, simply said he lost : D

I don't wanna bring anyone down, and sometimes I tend to do that.

Apologies,

Love.

[paulandmo2007]

@justinllalor Or Fundamentalist Christians. LOL

[secrecyXable]

Easy to imagine

[kiewefrog]

Jesus was the greatest mind of all? The Flying Spaghetti Monster was the single greatest sentient mind of all time. Ramen

[FSMonster]

@kiewefrog

I shall reward your faith: Italian or Asian noodles?

[TheOriginalLight12]

6 people really wanted to see what clever dislike comments people had.

[christuimbirek]

the want of the water drop to touch the other reembles very much our want to survive and eat and sex don't it

[christuimbirek]

hahaha the top comment i hilourios

[TheInternetFail]

Perhaps all rubberbands need to snap; there as to trac, the infinite the lap, and anable the future to make a map of the cat.

[majestic93]

@guyNbluejeans Very true indeed!

[guyNbluejeans]

@majestic93 After I posted my comment I went to Wikipedia and learned that he was an avowed atheist, so for that reason I have to take back what I said.

Now removing the post.........:-(

[majestic93]

@guyNbluejeans Yeah, imagine that. The greatest mind since Bohr, Planck, Einstein (and so on) was an atheist...

[guyNbluejeans]

@majestic93 And the greatest mind of them all (save for Jesus) was Newton, who was anything but an atheist.

[majestic93]

@guyNbluejeans And Newton didn't know one millionth of the things we know today.

By the way, who created god?

[guyNbluejeans]

@majestic93 You should consider changing your name from majestic to comical, it would be fitting considering ..

[majestic93]

@guyNbluejeans Why don't you go do something stupid so that you die and physically ascend to heaven?

[guyNbluejeans]

@majestic93 I've been responding to you, is that stupid enough?

[paulandmo2007]

@majestic93 because THAT would prove Darwin right!! hahahahaha

[majestic93]

@paulandmo2007 What?

[floopsie666]

@guyNbluejeans Jesus was a great mind? What an insult to physics! Here are these brilliant minds working hard to discover facts of the universe and you say the one, worthless, unknown facet of some idiotic religion was a brilliant individual?

[ArmandoXIII]

@guyNbluejeans

Search for "Neil Degrasse Tyson God of the Gaps" in youtube, you will understand then why Newton was a believer.

And lol at Jesus being the greatest mind.

[guyNbluejeans]

@ArmandoXIII I read Richard S. Westfall's bio of Newton so I doubt this Tyson fellow will shed any new light ... I'll later look into him just the same.

Why do you laugh at my assertion that Jesus Christ was the greatest mind this world has ever seen? Every intellect there ever was, is, or will be doesn't collectively make the grade to where His is (or was while on earth).

[savagecabage]

@guyNbluejeans Jesus's intellect > Every intellect that ever was. thats the daftest thing that ive heard all evening. what did jesus do again? how did he make our lives any better? amazing.

[guyNbluejeans]

@savagecabage If you need to ask, you can't understand. So I won't bother.

[savagecabage]

@guyNbluejeans yea your probably better off not bothering actually, ive heard plenty of it before believe me im sure you would be just repeating it

[guyNbluejeans]

@savagecabage Yeah, I'm sure you've had lots of conversations about comparing Jesus' intellect to others.

[looni3]

@guyNbluejeans Jesus was a primitive nomad who lived over 2000 years ago. He had some important lessons on how society should conduct itself but Richard Feynman's knowledge of the natural world dwarfs his. I can't get over how pretentious Jesus must have been to genuinely believe he was the son of a deity.

[guyNbluejeans]

@looni3 Correction. Jesus is Lord and Savior of the World!

Cute effort to try and marginalize Him like that, but soon time and events will make clear that He's the real deal. Stay tuned!

[montrey666666]

I wanna be this guys' kid...think about a bedtime story:) O...M...G...!

[Antharis79]

To be honest, I think that with over 1185 "likes" it is very likely that the 5 "dislikes" just came by accident...

[matthewdoucette]

6:45 ... love the ending. school takes the fun out of everything, as well as takes the will to learn out of everything.

[Beuma]

Is it a cell phone in Richard's pocket?... I don't when the cell phone came up, but 1983 seems a little early for it....

[JBOPatrick]

@Beuma Looks like an eyeglass case.

[0nfir3]

the second part is wrong.. the bike pump heats up because the pressure not because the handle comes down fast.. the smaller space ends up having double or more atoms and collisions with surface of pump also become considerably more frequent, thereby heating it up

[looni3]

@0nfir3 Yes but what is causing the pressure? The handle coming down fast. What he is describing is pressure.
