Entropy is everywhere, even in our daily life. We don't realize it. For example, there are two libraries A and B. Both these libraries contain exactly the same number of books. All the titles available in library A are available in library B as well. Imagine that library A is well stacked and library B is just a huge pile of books and all the books are just dumped. As per the first law of thermodynamics, both these libraries are equal, (energy is conserved). But anyone who wants to take a book and do some reading will prefer library A only, which is well stacked and ordered ( Less entropy). Library A has less entropy and more order. While B has higher entropy and less order. We need to spend energy to bring it to order. So basically entropy is a measure of disorder or randomness. Higher the disorder higher the entropy. We cannot measure/calculate entropy for all the process or in other words it is very difficult to measure the entropy for some processes. There are equations for some standard engineering and chemical processes to calculate entropy. If entropy associated with a process is very high, the process tends to have low efficiency. Ref: Thermodynamics : An engineering approach. Y A Cengel
-Lucy- -He- entropy can be also describe as a process of order to disorder. like a brick wall, their are many ways to break it but only one way to fix it
No you aren't. The energy you use to tend to the garden ultimately becomes warmth and dissipates. The energy making those plants grow comes from the sun, which is burning up to do so.
Jeff Philips: "The chances that the icewater will make the coffe warmer are 0,0000000000003." Me: "So you're telling me there is a chance!" Jeff Philips: "You did not understand one word in this entire video did you?" Me: "Not a single word."
I watched this a year ago for my thermodynamics course and didn't understand any of it. Just watched it again and it made A LOT more sense. Just come back in a year dawg
I’d you’re in high entropy that means your energy is spread equally. Which means your desorden or randomness is high. Low entropy would mean you’re energy is concentrated., so your randomness is low
I think this was the best explanation of entropy I've seen. I always hated when professors described it as disorder to me because that begs the question, 'well what is disorder?' That is why I am always so careful to describe the statistics of entropy to my first year chemistry students. My one suggestion for your video would be to talk about translational entropy instead of vibrational/rotational energy because students tend to have a very difficult time conceptualizing bond energy unless you explicitly describe it in more detail than just stored energy, whereas kinetic energy is more intuitive for them.
Yes, as a student chemist, entropy has always been a term I felt acted as a barrier to understanding the fundamentals. This is definitely the quickest explanation where I thought it was done well, but some books explain it very well as well
"I think this was the best explanation of entropy I've seen. I always hated when professors described it as disorder to me because that begs the question, 'well what is disorder?'" That has always been a bad definition to me also. "Disorder" is both subjective and even if it is disorder... we need another explanation about what disorder is. Leading us further and further away from understanding entropy.
It is, though tbh I wouldn’t know if it’s better than my teachers explaining it… I didn’t pay attention in high school lol. The other comments are hilarious though
I read a joke when I was in the university about a professor who gave the same question for decades in exams asking pupils to define entropy. Several years later a colleague questioned why he was repeating the said question. The professor replied that although the question about entropy is same all the time I simply change the answer! This video is an excellent example of how confusing entropy can get.
I heard it was Einstein and the exam was about general relativity or something like that. He would give the same questions. When other professors asked him to change his questions, he said answers are always changing. It's not that he's changing the answers, it's the scientific discoveries. Without science changing the answers, one professor cannot have different answers to the same question.
"Entropy is the direct measure of each energy configuration's probability..." This is the most exact and best explanation I have ever heard. It immediately clicked once you said that. Thanks 😊
Not a measure of energy configurations at all. When Clausius defined entropy as the sum of infinitesimal changes in heat at temperature T, he was talking specifically about heat as a macro quantity. Entropy is a mathematical statement of the 2nd law of thermodynamics which determines the direction of heat transfer in a process. If the process is reversible, entropy is zero and if irreversible, entropy is positive. Simple stuff, actually.

Thank God someone took the time for explaining this. This makes so much sense. When people said entropy is from order to disorder, it never made sense to me.. Cuz how do you define order?
This is an absolute beauty. We can actually apply the permutations and combinations we learn in high school for finding the number of microstates of a particular energy configuration, which is mind blowing. This is a video worth spending time on. Kudos to the presenter.
Brilliant explanation! I don't understand why there are so many people in the comments that claim that this was poorly explained. It made perfect sense to me, I'm sure there are people that agree.
The thing is, even if the unlikely happens once, you're still rolling that metaphysical quintillion-sided dice over and over again and the next shift in energy is still more likely to spread out again than otherwise. So you probably will never have to worry about your coffee getting hotter on its own or the mug exploding at random.
If you look at the glass of ice in its small scale, you’ll probably observe that some of the “units” are getting some energy here and there, thus getting hotter in some places counter intuitively, but as you look at the bigger picture, that gets negligeable, and in the long term it will cool. Also it would need to happen repeatedly in order to cool down, since its a continuous process. Another thing to take account is that in the macro world it might have no chance to happen, since when reaching a certain amount of factors the thing gets too defined to act otherwise, for example kicking a ball: there might be a chance for some energy to spread more to the right or to the left of the ball, but actual no chance for the compound to move in the opposite direction, the chances might just be zero for that, since all thought there could be a set of possibilities, that set is not infinite, rather limited. The conclusion is that in nature, not anything can happen, a defined amount of things in a point in time can happen, of which I wonder a lot about its actual nature and functioning, real randomness etc. These are just some of my thoughts, hope to give insight not certainty.
I’m surprised that people found this explanation confusing, I found the concept of entropy being the probability of energy “jumping” from a bond to another randomly really helpful. I guess the definition “entropy is a measure of how spread out energy is” is much less confusing than the “disorder” definition
It's one of the most difficult topics I encountered while studying physics, and the way you explained it here made me understand it so well, thank you so much! Sure there's way more to say about it, but for a first approach, it was GREAT! Keep up the good work, keep educating the world, it's amazing! :)
Okay- this literally doesn't help me with anything in school and it's not something I need to learn- but it's so calming 😌 I could literally watch it all day 😃
This is the most comprehensive explanation of entropy I have ever found. Neither my chemistry teacher nor the textbook explained it so thoroughly and with such clarity. Instead of the usual complicated explanation, your way of defining it as the redistribution of energy along the atomic bonds in a dynamic system is so much simpler. I really appreciate this video.

Very well put explanation. But to sum up this video for anyone who finds this. Entropy: A term of thermodynamics that (in laments terms) talks about the statistical probability of energy dispersion (and does it in some incredibly confusing ways). I’ve gotten this questions as well, it isn’t a force or aspect like gravity in physics, like this video said entropy is just what we use to describe things, it itself doesn’t do anything.
beautiful explanation ever. i became excited once i understood this concept and ran away to increase my entropy due to the increase in energy in me duiring excitation.
At times, I come back to videos like this to again ponder fundamental questions I already had answered. And THIS one was absolutely beautiful. Thanks a lot!
13 13 never sea every see sail away nervous watch me beliefs but before you go i got too we am i alone or is this just me ill hold my tongue as these breath our leased say that again airs waisted left us just be repeat d-q p-b get it teddy QXVII
@Dr Deuteron It's not. OP is SOMEWHAT wrong, Entropy is measured in Joules per Kelvin, that alone tells you its not a measure of energy. That being said, it can be argued that it is PROPORTIONAL to the energy that can't be used... Its complicated and I would have to look through my thermodynamics notes to verify
I specifically came here to understand Entropy since some speculate that it's going to be main concept in "Tenet" , Turns out its explained clearly here ( I rewinded and play it a few times though )
Im normally a very confused person, and yet somehow I find that after this video I’m not confused at all 😭 this actually helped me understand the basis of thermodynamics!! Tysm
I'm almost 75 and my brain is suffering from entropy. Just like air leaking from a hole in a tire, knowledge and memory are leaking from my brain, and strength is leaking from my muscles. Ah to be young again.
Because this concept is so complicated to grasp I accepted the notion that entropy is the measurable tendency systems have to find stability. Without in-depth knowledge of hard physics this is a something my tiny brain can comprehend.
This comment section: 50%-THIS MAKES NO SENSE 40%- I can understand this with my superior intellect so I shall share my knolage and scientific theory with you. 10%- heyyyyy madoka magica fans! Who wants a contract?
Conclusion : - Entropy can happen at everytime. - Chances of entropy if it is spread out is high as energy will move around and will move to other object. - When both of the entropy of the object is going to stabilise, both object will have same temperature. - It have 13% chances for one object to be hotter and another object to be colder as energy will move around... and theoritically will only happen in vacuum because the energy will also lost to the air surrounding... - Quanta is the unit of energy... - More energy higher the temperature. .... Anyway for my own opinion I think that entropy is related to probability and combination and even permutation meaning it is related to additional mathematics. More I think that the energy will be stabilise or will be equal in each object all is because of the probability of the entropy. For real I only understand most of the video but some I really do not understand it ... it could be 80% to 85% understand and 20% to 15% not... And wait my question here is... • will the size determine the entropy and the energy transfer between the bond and will effect the temperature changes in the object? • Will energy still move from colder to hotter one and will it only happen in vacuum or is it possible to happen at the normal environment with air? • Is Earth an example of entropy? And is Sun or other Star the example of entrophy?
I think understanding that energy dispersal is the key factor can be confusing for some because when explaining that energy dispersal is more likely because it’s statistically what happens feels like saying “the answer is the answer because it is”. I think this video did a great job connecting the two. What is causing energy dispersal to be more statistically evident? I think of it as “if a system adopts more micro states(and is therefore more stable ) then loss of energy/cooling effect will be a spontaneous process.
I've never thought that something simple as entropy could be explained in a such convoluted, unimaginative and let's be frank intentionally complicated way.
@@ericvauwee4923 not every comment has to be a new, better video. You can just comment. And I contributed a lot. Maybe someone who is also confused but feels that a better, simpler and clearer explanation exists, will read my comment and realise that he is not alone. There are many vital reasons why bad and convoluted explanations are detrimental. You might feel that your logic is somehow wrong or that you are unable to understand. And just for that it's important that someone writes down what I did.
This legitimately has been the clearest explanation of entropy that I have entertained. The question I have at the end of it all is, how is this going to stop my fried eggs from burning on the bottom of the pan?
Beautiful description of entropy. Yet I wonder, could we experimentally verify the change of entropy for unlikely processes? For example 1 molecule and see if it will heat up spontaneously? While the other will cool down.
The guy at the end definitely died when his energy “spread out”. With enough time, everything dies. That’s entropy. Even if that hot object got hotter, it wouldn’t be eternal, and it would eventually cool again. We as human base our lives and governing systems around people, beliefs, and current systems that are suspect to entropy. So there’s a seemingly long process of ebb and flow, though we, and civilization as we know it will eventually come to an end. Interesting stuff!
So what you're telling me is that if I shot a bullet, there is a chance all the energy from it will go into the air, the bullet will just stop mid flight and create a gust of wind? Achievement acquired : Air bending discovered
I was doing my assignment on entropy and came to RUclips for suggestions. And, this was on my suggestions list before even I looked for it😂😂 thanks Ted Ed!! 😊
This is the best explanation of entropy I ever came across... Entropy is better to be visualised as the probability of distribution of quanta in the microstates...it further leads to the Boltzmann equation S = k log (omega)
So basically: High entropy= energy is split equally everywhere low entropy: energy isn't split equally although there is nothing preventing it from happening except probability is that correct?

Entropy is everywhere, even in our daily life. We don't realize it.
For example, there are two libraries A and B. Both these libraries contain exactly the same number of books. All the titles available in library A are available in library B as well. Imagine that library A is well stacked and library B is just a huge pile of books and all the books are just dumped.
As per the first law of thermodynamics, both these libraries are equal, (energy is conserved). But anyone who wants to take a book and do some reading will prefer library A only, which is well stacked and ordered ( Less entropy).
Library A has less entropy and more order. While B has higher entropy and less order. We need to spend energy to bring it to order.
So basically entropy is a measure of disorder or randomness. Higher the disorder higher the entropy. We cannot measure/calculate entropy for all the process or in other words it is very difficult to measure the entropy for some processes. There are equations for some standard engineering and chemical processes to calculate entropy.
If entropy associated with a process is very high, the process tends to have low efficiency.

Thanks what is thermodynamics
Yes but it's also very easy to make a mess in library A. Which should be the priority if entropy always increases.

This is the most comprehensive explanation of entropy I have ever found. Neither my chemistry teacher nor the textbook explained it so thoroughly and with such clarity. Instead of the usual complicated explanation, your way of defining it as the redistribution of energy along the atomic bonds in a dynamic system is so much simpler. I really appreciate this video.
Why did I find it not so easy to understand 😅

Very well put explanation. But to sum up this video for anyone who finds this.
Entropy: A term of thermodynamics that (in laments terms) talks about the statistical probability of energy dispersion (and does it in some incredibly confusing ways). I’ve gotten this questions as well, it isn’t a force or aspect like gravity in physics, like this video said entropy is just what we use to describe things, it itself doesn’t do anything.
Thank you for making this so much clearer. Most videos say entropy happens "just cause" whereas you actually explain how and why.
4:50 every time I finish a TED video

I had a really bad day today but your comment made me laugh. Thank you.
Yes! 😂
stonks.
You become a super saiyan? 😂
beautiful explanation ever. i became excited once i understood this concept and ran away to increase my entropy due to the increase in energy in me duiring excitation.
Now i have an excuse for the mess that is my desk
That is I, indeed.

"We live in a twilight world. There are no friends at dusk."
So violation of 2nd law is improbable not impossible
That means that 2nd law of thermodynamics in not a law it is statistics.
I should have more research on this.
It's a statistical law.
Depends - how many zeros does the probability percentage need to be considered impossible? :)
It’s impossible to do on purpose.
Yes i recently read a article where scientists observed a disordered set of quantum states going back to ordered state violating 2nd law
Entropy is a measure of the amount of energy in a physical system that cannot be used to do work
Why can't it be used
@@thatcoffeefeel8 because it is unordered energy.
Divyansh Verma: Excellent. I prefer your explanation.
@Dr Deuteron It's not. OP is SOMEWHAT wrong, Entropy is measured in Joules per Kelvin, that alone tells you its not a measure of energy. That being said, it can be argued that it is PROPORTIONAL to the energy that can't be used... Its complicated and I would have to look through my thermodynamics notes to verify
What is this, high school physics? OP did a great job over-simplifying entropy, basically telling untruths to make people believe they understand.
I'm watching this video for the third time now. Each time I watch it, I get it. But the concept evaporates from my mind with time.
This is the best explanation about entropy meant for the laymen I've ever seen! Kudos! 👍👌👍👌
L Galicki I agree.
L Galicki Band this vudeo gives me another reason to hate and lovr quantum.mechanics more
I specifically came here to understand Entropy since some speculate that it's going to be main concept in "Tenet" , Turns out its explained clearly here ( I rewinded and play it a few times though )
One of the very few easy explanations of entropy out there
Probably the best, must succinct elucidation of how entropy functions that I've ever seen. Thank you for the insight. :)
See Brian Cox from the BBC explaining it, too, just excellent.
When I was 10 I asked my science teacher why do hot things get colder and she said no one knows , glad I finally got the answer.
Im normally a very confused person, and yet somehow I find that after this video I’m not confused at all 😭 this actually helped me understand the basis of thermodynamics!! Tysm
Thank you, DAY6. My curiousity sparks more bcs of your album.
Now I understand entropy better than before. Thanks!
so a 5 min video cleared out my misconceptions, and thats what i love about teded
At 4:48 , it went full interstellar.
I'm almost 75 and my brain is suffering from entropy. Just like air leaking from a hole in a tire, knowledge and memory are leaking from my brain, and strength is leaking from my muscles. Ah to be young again.
This is life my friend 😀

Larios Photography Translation I don’t get it😜
Because this concept is so complicated to grasp I accepted the notion that entropy is the measurable tendency systems have to find stability. Without in-depth knowledge of hard physics this is a something my tiny brain can comprehend.
This comment section:
50%-THIS MAKES NO SENSE
40%- I can understand this with my superior intellect so I shall share my knolage and scientific theory with you.
10%- heyyyyy madoka magica fans! Who wants a contract?
😂
Hey, you! Yeah, you! Wanna make a contract?!!!
Now:
Almost all comments:
"TeNeT"
1%-TENET
5% tenet gang
Conclusion :
- Entropy can happen at everytime.
- Chances of entropy if it is spread out is high as energy will move around and will move to other object.
- When both of the entropy of the object is going to stabilise, both object will have same temperature.
- It have 13% chances for one object to be hotter and another object to be colder as energy will move around... and theoritically will only happen in vacuum because the energy will also lost to the air surrounding...
- Quanta is the unit of energy...
- More energy higher the temperature.
....
Anyway for my own opinion I think that entropy is related to probability and combination and even permutation meaning it is related to additional mathematics. More I think that the energy will be stabilise or will be equal in each object all is because of the probability of the entropy.
For real I only understand most of the video but some I really do not understand it ... it could be 80% to 85% understand and 20% to 15% not...
And wait my question here is...
• will the size determine the entropy and the energy transfer between the bond and will effect the temperature changes in the object?
• Will energy still move from colder to hotter one and will it only happen in vacuum or is it possible to happen at the normal environment with air?
• Is Earth an example of entropy? And is Sun or other Star the example of entrophy?
Ok, so what's entropy
Entropy is also in thermodynamics
I think understanding that energy dispersal is the key factor can be confusing for some because when explaining that energy dispersal is more likely because it’s statistically what happens feels like saying “the answer is the answer because it is”. I think this video did a great job connecting the two. What is causing energy dispersal to be more statistically evident? I think of it as “if a system adopts more micro states(and is therefore more stable ) then loss of energy/cooling effect will be a spontaneous process.
"Madoka...do you know the word 'entropy'?"
Gratio I see you're a magical girl of culture as well
Contract anybody?
Madoka, lika most of us, probably had absolutely no idea of what entropy was.
Been waiting for this comment.
Didn't expect a PMMM reference in a TED video
I've never thought that something simple as entropy could be explained in a such convoluted, unimaginative and let's be frank intentionally complicated way.
And instead of doing it better you wrote this comment lamenting how superior your intellect is without contributing any value at all.
@@ericvauwee4923 not every comment has to be a new, better video. You can just comment. And I contributed a lot. Maybe someone who is also confused but feels that a better, simpler and clearer explanation exists, will read my comment and realise that he is not alone. There are many vital reasons why bad and convoluted explanations are detrimental. You might feel that your logic is somehow wrong or that you are unable to understand. And just for that it's important that someone writes down what I did.
This legitimately has been the clearest explanation of entropy that I have entertained. The question I have at the end of it all is, how is this going to stop my fried eggs from burning on the bottom of the pan?
Beautiful description of entropy.
Yet I wonder, could we experimentally verify the change of entropy for unlikely processes?
For example 1 molecule and see if it will heat up spontaneously? While the other will cool down.
The guy at the end definitely died when his energy “spread out”. With enough time, everything dies. That’s entropy. Even if that hot object got hotter, it wouldn’t be eternal, and it would eventually cool again. We as human base our lives and governing systems around people, beliefs, and current systems that are suspect to entropy. So there’s a seemingly long process of ebb and flow, though we, and civilization as we know it will eventually come to an end. Interesting stuff!
Hey at least he died happy and bombastic. I wish I could go out like that.

This is the best explanation of entropy I ever came across... Entropy is better to be visualised as the probability of distribution of quanta in the microstates...it further leads to the Boltzmann equation S = k log (omega)
They were trying to make it simpler for us but everything they said made less and less sense and became more complicated lmao
Now I know the actual reason behind the mess that's keeps on happening in my life.
It's entropy
This actually helped me understand what Sean Carrol was talking about…micro states and probability. Thanks.
So basically: High entropy= energy is split equally everywhere
low entropy: energy isn't split equally although there is nothing preventing it from happening except probability
is that correct?
