Excellent video! Except that the last statement is incorrect about -273C. As predicted by Bose & Einstein, and demonstrated since 1995, we end up with a new state of matter once you hit -273 and remove all the motion. That is the BEC state of matter, or a Bose-Einstein Condensate. Molecules are no longer distinguishable at that temperature.
A lot of people mistakenly believe that infrared radiation= heat. While it often results in heat, or is a good indicator of such, it is not itself heat. This should help clear it up!
One can argue, that movement is what defines the matter/energy as a whole, and the Universe is but a contrast between energy, that always moves, and space, that never does.
+johnny chang With string theory, perhaps. I know for a fact some vibration modes don't actually happen because the amount of energy changed in bringing some atoms closer or farther together wouldn't be quantified, so maybe that energy translates to movement in one of the 11 dimensions described by string theory? I have no idea :D
For the last couple of months inanimate objects move. Pictures look alive…decorative flower arrangement, the petals or stems move around. I almost feel crazy, but I find it fascinating. I don’t know what’s going on lol. Even my blanket, if I stare at it, it’ll start moving as if there’s something in it. I even have a 6” ceramic Gnome that was my dad’s…this thing dances. I’m losing it haha
Those atoms are so damn cute! 😫😩 I just loved the vid and I'd give it 5 stars for the atoms and 5 stars from my side for explanation! Just loved the video! ❤️
Amazing!!!! Quick question, What about the moment when a molecule is freed/released/migrate from the current structure to let's say another matrix like for instance the migration of some compounds or elements like lead to the food its containing from the packaging material? The migrated element or compound was done because it was loosely bound or due to being in an amorphous area while crystalline needs more time/temperature?
no tachyons do not exist. Imaginary mass particles do not exist, even though they are a result of the erroneous bosonic string theory and the emission of Cherenkov radiation. Modelling by Lorentz invariance in the Standard Model, it is extremely unlikely that these superluminal particles exist. The problem with tachyonic condensation is also described in detail in the low-energy Yang-Mills description of a multiple D-Brane quantum system.
larger and larger collections of simple things interacting via simple and predictable rules increases in the complexity of and information contained in the system and that's what people are. A complex physical system. It is amazing, but most people don't understand it and fall for the illusion that we have an immaterial soul that acts and decides independently from the physical universe around us
+Derek Rodrigues Well, people who believe in immaterial soul and etc don't have the brain capacity to understand the world around them. They believe they need to worship a higher power. But in the matter of fact, we humans should understand what is around us, and hopefully soon be able to enjoy our short sharp of existence.
+Pizaerable It's not that they don't have the brain capacity, it is statistics. Most people never understand the mechanism of self, nor the mechanisms of the universe, but that isn't necessary their fault. For the individual has to seek these things, but there are so many distractions in our way to see it. It is sad really, but this is just part of the human condition. Once a human truly sees, he/she is no longer animal-man, but man-animal. This is minimal amount of info on these topics, however I am always open to discussion.
First thought is what happens at the quantum level when observation happens. When does movement stop within the quantum realm? Am i misinterpreting how the quantum realm works? Was that the answer at the end?
So at room temp translation motion has highest contribution, but at high temps since the molecules are taking so much heat in do they contribute more than translational or no?
I have a question, say you had a numerical ticker, that goes up 300,000 ticks per second. It's just that the ticks are numbers it's like a digital clock that goes the speed of light. now if the numbers were changing ( increasing 300,000 digits per second ) would you be able to see the the numbers or would it just be, depending on the color of the numbers, a red blur or would you not see anything because light photons would never reach you because they're changing (digitally) faster then light.
+BrownFire Wood The clock is not going faster than the speed of light as speed is distance per time not ticks per time. It would be theoretically be possible to make a camera that can record the clock as it changes as 1/300,000 of a second isn't the plank time, the smallest unit of time in the universe, that could then be slowed down to show the clock as it changes. The reason that it would reach you is that while it changes almost instantly (relative to human perception) if it actually did flash a number every 1/300,000 of second then light (which can be detected) would have to be emitted. However, an interesting consequence of it flashing so fast is that since the number changes after light from it has come out of it by a meter (how far light goes in 1/300,000 of a second) the number you record will be the amount of meters you're away rounded down less than the actual time it displays.
When physical qualities of a molecule are given , sometimes even the bond length and bond angle are specified . If the they keep changing, how are they calculated?
at 3:50, he says that when infrared radiation is emitted by the sun, the water vapor and carbon dioxide molecules absorb this form of energy and then speed up and get warmer. i get that part. but then he says that as a result of getting warmer, they emit their own infrared radiation, which then gets absorbed by the Earth, and the Earth gets warmer. So is he saying that global warming is when the Earth itself gets warmer, and not the atmosphere? Because I always thought that global warming only affected the atmosphere, so I guess I learned something new. Also, why do water vapor and carbon dioxide molecules emit infrared radiation when they heat up?
Global warming is both the atmosphere and the earth heating up at the same time; you can't heat one without the other getting warmer. As for radiation, literally everything emits thermal radiation, it's just that most objects don't emit it as visible light. Think of an infrared camera, it shows you things based on temperature because it detects the infrared thermal radiation that all objects give off, not because of reflected visible light like a normal camera. On the other end, have you ever seen red hot or white hot metal? That's a case where the object is so hot, the thermal radiation has shifted higher in energy and is emitted as visible light instead of just infrared.
rotation of linear molecules along their axis is not possible or counted I thought because that no torque or force can be exerted this way. not because that the position of atoms do not change!
Those two statements mean the same thing. Torque cannot be applied *because* there is no extent to exert force on, the "r" is effectively zero. Thus there is no angular momentum in that node and thus no change in position along that axis.
Broken Program i always wondered how molecules moved (behaved) in extreme conditions...like how they would it be when the environment around them is hot or cold or stuff like that...
Amazing video, but there is such a thing as colder then absolute zero first achieved sometime in the early 1950s by the nuclear magnetic resonance experiments of Pound, Purcell, and Ramsey. This leads many scientists to believe that temperature is a loop rather than a linear scale. Possibly next video?
" After we're gone " 😭 i felt sad when i heard that, knowing that we only have 3 - 4 years to live in this awesome planet 😢 Lets save the earth before it's too late!
the more DOF s the more energy can either absorb or emit and of course this has to do with green house effect and utterly with climate change. Further explanations about angular momentun and black body radiation would complete the understanding about this
doesn't it only take 2 variables to describe the orientation of an object? think of spherical coordinates. they can point in any direction with just two variables.
atoms don't look like people. but what if every subatomic particle is a whole universe? :O what if we are a life simulation of a fat Sims 1357² player. what if you are part of my creation? or I was created by you?
+Avs minhas I thought something like that but I assumed the atoms are minute solar systems (nucleus = sun, electrons = planets) and these solar systems help make up minute galaxies which form greater masses... therefore, on the atom are smaller beings living on them, like we are living on parts of an atom that make up a greater mass together with the rest of the galaxies...
I thought this video was about still objects crossing a distance if left alone for a very long time. Like a vase on a table falling off after a thousand years.
+Erik Jarl Heisenberg's uncertainty principle states that one cannot measure the position and momentum of a particle simultaneously. So if a particle is at rest, one could simultaneously be able to figure out it's momentum and position. Now I don't know why it is this way. Ask a physicist.
This video makes a great effort to define degrees of freedom of molecules and shows how to calculate it. But there is no single use of this concept in the entire video. A definition is a pointless thing, unless you use it.
Whoa! My body is constantly moving. Another great excuse for not going to the gym!

Everyone is replying to +011 but he/she hasn’t written any comments here wth
Awesome lesson - as a science teacher I really appreciate this type of great work :)
The animated molecules are so cute and it just cleared my concepts 😀😀
Thank you TED Ed. This is one of the best.
Cool! Keep these videos coming! They're pretty interesting and simply put.
Wow. Amazing explanation. Degree of freedom, greenhouse effect, microwave , motion at absolute 0. Learned a lot. Thanks
Damn this will help me A LOT!!!!! Thanks!!
+Kuka Weber was that sarcasm?
+islezeus nope I wrote a test about it
+Kuka Weber relax honey, my comments have been tongue in cheek
+islezeus ahhh pinto grande preto!
+Kuka Weber obrigado, menina
It is so useful information. I appreciate your effort to explain the molecular motion
This video reminded me the concepts, I was taught in thermodynamics, and rotational and vibrational spectroscopy in quantum mechanics.
He likes to move it move it, she likes to move it move it, we like move move it, we like to MOVE IT!
Hahaha
Hahaha
Hahaha
Hahaha
Kudos to the animation team. Brilliant stuff.

Amazing.... I learned this in 12th std chemistry but whoaaa... it just seems so simple now....
I was pondering this the other day and now this video gets uploaded, thank you!
Thinking about infinite give me chills every time.
Do more riddles!!!!!
A lot of people mistakenly believe that infrared radiation= heat. While it often results in heat, or is a good indicator of such, it is not itself heat. This should help clear it up!
+djayjp I have never heard that once in my life just link whoever thinks that a wiki page or two about those topics xD
Lord lima bean For instance someone might say "thermal vision" instead of infrared vision. But yeah ha
Who knew molecules could be so cute >.< I love when one of them is dancing to the boom box towards the end.
Perfect video that answered all my questions and then some. Thank you!
Excellent.
Do you have video on zero.point energy?
One can argue, that movement is what defines the matter/energy as a whole, and the Universe is but a contrast between energy, that always moves, and space, that never does.
This is very helpful for our 1st year thermodynamics chapter
Piece of art!
Great Video!
hi
Is possible for complex molecules to move in like 4D fashion like in an hypercube? Say certain aromatic compounds with the benzene structures?

Extraordinary great explanation
I love how Richard Feynman describes "jiggling" of everything.
Do modes of vibration have anything to do with acoustic levitation? Do vibrating sound waves affect different molecules in different ways?
Incredibly useful
Gee.. This is very clear explanation.. Thanks
Wow It is amazing! What a great Explanation.... Thank you Very Much...

Great animation!
I need know, what is the practical application of this knowledge?, please
Very Useful Channel for Stuff!
thanks ted x . for animaton
How did we discover what the angle of the atoms towards each other is? That would be a great topic for a future video :)
+Descalabrox
as a rule of thumb: VSEPR-model,
the exact value can be calculated theoretically and measured/deducted from the resulting IR spectra.
I wish you had gone into more detail about zero point energy. Think of the tachyons…
no tachyons do not exist. Imaginary mass particles do not exist, even though they are a result of the erroneous bosonic string theory and the emission of Cherenkov radiation.

ohhhhh. im finally realizing that those thermal maps are showing emitted radiation. thanks!
pls try to make video on absolute zeeo temperature and what happens to matter at that condition.
I meab zero*
+param patel
Nothing, as this can never happen (3rd law of thermodynamics). It's impossible to get to 0K.

Weird, this morning i attempted a bowel movement and it didnt move at all!!
Much better than my chemistry class
Excellent... thanks 🙏
Amazing way and even its interesting 👍👍
The animation is so adorable....but I couldn't understand the 3n-5 etc..
+epic muzik thank u so much:D...but does 3n-6 mean 3 times n minus 6 or equal to 6
Can I use sound energy to heat things up
rotation of linear molecules along their axis is not possible or counted I thought because that no torque or force can be exerted this way. not because that the position of atoms do not change!

+Akshay Kumar
what is it?

The high speed of air molecules ain't letting me sleep. When these molecules gonna slow down

Does same atoms have dipole moment and vibration!???
did the universe have a first moment? or was it always here?
" After we're gone " 😭 i felt sad when i heard that, knowing that we only have 3 - 4 years to live in this awesome planet 😢 Lets save the earth before it's too late!
Can elementary particle such as electron have a temperature?
+Alexander Pushkin
sure. The hotter they get, the faster they move (at least until relativistic effects set in and relativistic mass increases)..
good one
What about moving elektrons?
I just want to say the atoms were so adorable
at the end of this video. say the absolute zero temperature, why is the molecule still moving? . I do not understand the author of this article
Because atoms still have to move regardless of their state or environment. It's the universal law of vibration. Universal laws cannot be broken.
How can I get the video's script ? I cannot find it here
the more DOF s the more energy can either absorb or emit and of course this has to do with green house effect and utterly with climate change. Further explanations about angular momentun and black body radiation would complete the understanding about this
I love his voice
The zero energy is not equal to 0, not because the vibrate kinetic, but the potential energy.
So, it's possible that the atoms stop vibrating at 0K.
Asymmetric should be antisymmetric. And yes there is a difference.
1:06 PARTY TIMMEEE!
Thanks
doesn't it only take 2 variables to describe the orientation of an object? think of spherical coordinates. they can point in any direction with just two variables.
+cubedude76 There's a third variable, that describes the object's rotation around the vector of their orientation.
And welcome to the world of vibrational spectroscopy.
Soon we''ll find a way to control those movements and separate matter at will.
So what moved the first atom?
+Caffa Jake Energy!
+Momchil Momchilov From where?
Caffa Jake Nobody knows.
Momchil Momchilov Does it even matter...?
: )
Caffa Jake Depends on you. If you want to know, then yes, otherwise no.
gotta keep up with the news TED, gas can apparently reach temperature below absolute zero.. which, I suppose, makes it no longer absolute
sacreblu! great video
Zero Point Energy? (Incredibles theme plays)
What is we are atoms to another creatures that are way bigger than us and the atoms that we observe are people that are way smaller than us.

The application you're looking for is IR and Raman spectroscopy. Degrees of freedom is a pretty important idea in physical chemistry.
+Renae A. Thanks for pointing that out. I don't doubt that it has applications. I just complain that the video fails to mention them.
the animator must not understand translation because each depiction shown has also included scaling and/or rotation.
