  • Actually, a dead cat bounce in the stock market is an actually bounce. It's the bounce in stock prices which often comes right after a big fall, but which does not signal an actual turn around. It's said to come from the idea "even a dead cat will bounce if it falls from a great height".

    I know economics and finance often steal terms from physics and use them somewhat incorrectly, but in this case it seems like it's the other way around.

  • George is Neil of Sixty Symbols. :p

  • a dead cat bounce, shrodingers cat (sorry for bad spelling), What do physicists have against cats?!?

  • @ISN1P3DI

    *Schroedinger or *Schrödinger

  • @ArsonistInUrFirewall Ahh, Thank you, i wasnt sure of the spelling :)

  • Interesting as always, but terrible camerawork.

  • Nice Watch bro

  • so because the particles on the greater side are loosing more energy due to higher collisions, if you felt the balls, would they be hot? I know some is lost to sound energy, but it sounds wierd that they would get hot because your bouncing them...

  • @TheMohanned94 They get hotter. Whether you would feel the difference or not at that energy level is another question, partially because the heat gets dissipated into the surroundings. The same thing happens in a super ball or any ball you bounce (i.e. a basketball). When the ball is bounced, or collides, the particles that make it up vibrate more due to the collision. This corresponds to an increase in temperature. How much the vibration increases depends on 'r' or how elastic the collision is.

  • what i observed here is this:

    when the amplitude is zero (zero energy) the height of the balls is small

    when the amplitude is higher (higher energy) the height is getting higher and higher and it looks like the stack of balls is bigger

    its like when an objects is heated it expands and actually it has the same cause since when and object is heated the atoms which consist it are oscilating with greater energies

  • But what happens if there is the exact amount of particles on one side?

  • Does anyone else think this correlates to Maxwell's Demon?

  • @cleatuslewinda It does seem similar but I think the Maxwell's Demon thought experiment occurs in an isolated system with no energy input. In this case however energy is being constantly fed to the system in the form of the vibrations.

  • My favorite color is orange, I have studied orange in art classes, I know the etymology of the word orange, my room is painted orange to the annoyance of my friends and family, every shirt I wear is orange to the annoyance of everyone, I have dyed my hair orange, I dyed my dogs hair orange (don't worry it was safe it was just food coloring,) on august 12 I dye my eggs orange not green, I have I don't particularly like the fruit orange, but none-the-less I KNOW ORANGE and THAT! IS ORANGE!!!

  • what if they were both exactly the same?

  • @umbracus he explained that at the end

  • George likes talking to pretty ladies.Nice George,nice. Pretty smooth moves :D

  • 3:40 Scientific conclusion: "And everone want's to cram in the most popular disco".

    This professor cracks me up. ^_^

  • @damianpaz "34^10's cumming everwhere". He really is great (From another video)

  • 1 person Doesn't know how magnets work

  • that is called revolution

    if you push your slaves they organize themselves and kick your ass^^

  • What happens when you use a round container with wedge sections, perfectly centered on the speaker, and level ?

  • @1isaacmusic You'll get the same result. Particles will tend to cram in the most populated divisions.

  • @Hax0rPr0n Yeah, well I'd agree that he over-explained it, but that's what is natural for a teacher to do when he has no response... Now, lets talk spirits.. talking to spirits through use of psychedelics or what?

  • My friend used to have that same little earth ball

  • @Hax0rPr0n Spirit ppffft. Freakin voodoo doing retard. So ur waiting for the freakin excorcist to come ttell u that speaker make balls bounce?

  • I so!! much love this vid!!!... I could listen to this guy more than I love listening to Waltor lewin from MIT..!!

  • @Hax0rPr0n Hahaha, what?

  • Now try it with dead cats...

    

  • A beautiful breaking of symmetry - Also a localised order from disorder - Excellent Vid

  • Great videos!

  • Huh.. So this is how the stars and planets are formed?

  • The balls in the emptier container collide less and thereby jump higher. THATS IT! why the 6minutes documentary lol

  • GAAAAAAAH im trying to follow the bouncing ball here folks, but theres just too many moving too fast!

    

  • 0:47 faceplant

  • Balls to you , sir!

  • What I mean is, can a microscopic machine be created using this effect to increase the order of a system simply through the vibration of its constituent particles?

  • Could this be used to violate the Second Law of Thermodynamics?

  • i have never seen anything like this. facinating

  • There was poor Schrodinger's cat, and now this dead cat bounce. Seems felines and physics don't mix :-)

  • isn't it the same principle behind the process of osmosis?

  • George is such a pimp

  • hello

  • A brilliant and an insightful explanation - this tipping point mechanism is the way stock markets, wars, political systems etc work - thank you - cyril anand.

  • Is this another way of explaining the 2nd law of thermodynamics?... as in why heat always flows from hot objects to cooler objects but never the other way around?

  • @supercal333 Or a simplified demonstration of the principle behind a Peltier cooler.

    When electric current goes through two different metal conductors, at the junction one end absorbs the heat of the other one, creating a temperature difference.

    Could be wrong though, it's one of those things I never really understood.

    For instance: the direction of the heat transfer could be controlled by changing the direction of the current... that's pretty cool, but why is that? I have no idea. :D

  • What an amazing experiment.

  • I never saw People dancing like this...

  • At 4:55 he says "collisions between the particles is inelastic", and "the coefficient of restitiution [(r)] is so much less that one that it's like a dead-cat bounce". This is UNTRUE! The beads actually have a HIGH r, maybe 0.9. A plastic bead bounces maybe 90%.

    What (I think) is REALLY happening is a statistics effect. The fuller side gets a more-averaged energy level because a particle with "escape velocity" will more likely encounter another bead and be averaged out before escaping.

  • @BCCbadgerb that's if the plastic bead is solid or unpunctured, these have a hole in them.

  • oh my God! I never thought they'd collect on one side!

  • Actually the dead cat bounce means that there is always a coefficient of restitution as related to finance - because "even a dead cat dropped will bounce once".

  • Outstanding!

  • 0:16 u hear some1 says again

  • @mohammadjj : that's Brady :)

  • take that entropy

  • @adamthecg Lol, problem is, entropy will move from high to low if you apply enough energy.... but funny comment anyways XD

  • @adamthecg Hehe. Entropy doesn't quite apply since energy is being fed into the system via the bass. :)

  • You have to remember that 2nd law applies to an isolated system. Through that loudspeaker they're tampering with the system.

  • How exactly?

  • Did he say fucked it up? LOL.

  • what will hapen if you add 3 newtons to each of the small balls?

    Or just make it heavy?? will there be a difference?

  • allow me to retort. is there a way to determine which way they will go if there is an = number of 'particles' on both sides?

  • I'm pretty confident it would be pseudorandom, depending on which side gained one ball first -- thereby losing more energy to heat, distortion, sound on that side with the additional ball.

  • He covers that question at 5:28

  • did yuo just read my one comment or did you see both?

  • 320iguy,

    no: 5:25

  • no i changed my question. it was answered reight after i hit enter. LAS

  • youtube keeps messing up the reply order, so i had to delete my other one, etc its all fked up. youtube/google didnt do a good job with the comment/reply code.

  • so what would happen if there was an = number of 'particles' on both sides?

  • yieh!

  • Oooooooo, bouncy =)

  • Great video!

    Well, I'm off to the disco now! Gonna get my groove thing on! Get funky!

  • hey ,i thought time travel was impossible , how did you get here from the 80s ?

  • physics is simple if you look at it in a certain way

  • @cookiecamp i guess if you put it put force on brick.. brick move

  • @stiffy14got9heedshot it depends on a few things though ; where the force is acting how high up the brick is, if there is any friction (air resistance or any other resistance) and of course the mass of the brick.

    if you want to learn more do A level maths and physics and it will all make perfect sense

  • @cookiecamp the "simplicity" of physics gets quite complex, if you look at it the other way.

  • @cookiecamp You mean when you look at it after someone tells you the answer?

  • cool

    really interesting

  • hey then the tension of mimicising among creatures may rely in this!nature is really complicated and non-understandable by humans.i feel so unimportant when i think about this stuff

  • he should put that on a giant subwoofer and play some techno...

  • This experiment is a big F-U to entropy...

  • um, it seems to require outside energy, so no its not....

  • very good

  • "I can tell by your shirt that you can't tell colours"

    EPIC :D

    This guy annoys me...

  • you know who bounced my balls last night ? : )

    sorry ,but i'm in a really god mood XD

  • where does gravity's energy come from? it seems to me that gravity is a near infinite source of energy.

  • i think gravity is an energy leaking form another universe or dimension, its properties are so different it cannot be fully explained with our universe's physics

  • You should read about gravitons, they have thought about extra dimensional stuff just like you said. It's very interesting :)

  • are you serious ?? do you even know anything about physics ?

    gravity is one of the biggest mysteries of science ,the standard model accounts for it through a sub-atomic particle called the graviton , while Einstein said it happens when large bodies -such as the sun or the earth- bend space ,causing smaller objects to fall towards it ,also gravity is a force not an energy

    watch the video called "gravity" from this channel ,it'll help you understand

  • im in 9th grade, i really don't. juuust trying to get my head around it all. and did that really answer the question? if so downsize the language plz.

  • there's two explanation of gravity ,one of them is the standard model of physics which was set by a group of physicists ,and they said that gravity is caused by a sub-atomic particle called a graviton ,and this particle exists in every atom and causes them (the atoms) to attract to each other ,however ,we've never seen a graviton nor detected it's existence ,and that's is one of things we're hoping that the LHC would do ,proving the graviton's existence .

  • i also don't understand the equations.... i though i was good at math 2.

  • and the second explanation was provided by Einstein's theory of relativity ,he said that space is two dimensional (like a piece of cloth or fabric), and huge bodies (like the earth or the sun) actually bend this two dimensional fabric ,causing something like a 3 dimensional hole which causes smaller bodies (like the moon) to actually fall towards those bigger objects thus giving the feel of gravity

    but you should really watch that video "gravity" ,it'll explain it much better than i did

  • Please stop giving Einstein credit for everything. It's getting old.

  • well ,if it is his theory then giving him credit for it wouldn't be so "old" ,besides ,i was just explaining gravity to someone ,i also mentioned the explanation provided by the quantum mechanics in a previous comment .

  • George is my favorite.

  • what would happen if both sides had the same number im assuming that the same would happen

  • he mentions that around 5:29

  • yeah lol literally just as i pressed 'post comment' it started talking about if they where = amounts (i felt very silly at that moment lol)

  • If both sides had the same number, due to human error, the side closest to the center of the speaker would bounce higher, it would have more energy.

    @rob0is0god

  • What if that side where the balls went is near a node in the speaker?

    That should affect it as well right?

    anyways.. You guys need a high speed camera for this kind of stuff :3

  • 2:44 What? :P

    Anyway, very interesting video (as usual)! It's always great to see something that at first seems to defy what you'd expect but then you hear a perfectly logical explanation for it.

  • What a wonderful video! I learned something.

    When showing what a physics algebra term means ("r" in this case), could you please also devote a little time to showing how it's used in an equation? Equations are the scary bit of physics to us laymen, and helping to demystify them would be a great force for good in the world.

  • Cool! I've never seen that experiment before.

  • was the camera man drunk?

  • Is this how the mechanics of diffusion works?

  • You guys should do an interview with George. Would be interesting to see what he does, and how he feels about things.

  • ... and who are the pretty ladies he's apparently been looking at?

  • Yep, we need to know!

  • The disco analogy was priceless, lol.

    These videos keep getting better and better!

  • @kbcbcofme: You were first in two places at the same time... clearly you have been watching our videos about quantum mechanics!

  • I did, lols....

    I watch all your videos

  • Hahaha clever :P
