***** Don't be too hard on yourself. Entropy is very difficult to understand... especially in a few minute video. I did a follow-up video and it's still difficult: ruclips.net/video/qQhv3YhiJ98/видео.html

2:47 If that collision happens in forward direction, some energy should be released. But if that same collision is played backwards (in time), as you showed in the video, then energy should be absorbed to “undo” that collision. Right? But that does not happen in real life. Even there we see that it’s not a reversible phenomenon. So, is entropy really emergent? Or is it inherent?
Between the _individual molecules,_ energy is certainly exchanged. In reverse, that energy is just exchanged the other direction. There's not room for "release." It's just two molecules. It's only on the normal-scale where we see irreversible processes. That's emergence.
I now understand, our lives, and everything else that is ever was or ever will be that exists has no point no meaning and no purpose.Reality is a gigantic chemical reaction of immeasurable quantity of atoms reacting with each other simply trying to maximise its entropy before the inevitable end. I feel so depressed now.
But nothing has changed about the universe from before you watched this video other than the way you think about it. no reason to feel any worse now than you once did :P
so entropy is more like a relative property? like when stored energy location is a known value it has order, when that stored energy is less, less of the original known energy is known thus less "order?" so, say the starting point stored energy (order) in a closed system relative to the ending point stored energy (order) is the measure of entropy? So say, the measure of stored energy at T1 vs stored energy at T1+n is what entropy is?
F!@#Guilt It's not really about how much energy there is or where the energy is... it's more about how "useable" it is (if you're looking for a simple word). I made a follow-up video for this that gets a little more in-depth: ruclips.net/video/qQhv3YhiJ98/видео.html
Theory: entropy is about the inflationary nature of space, entropy makes energy more "pneumatic" (inflated by space). Fundamentally, entropy is about separation. With separation, there comes a decline in usefulness in a focused manner. Low entropy energy has greater impact in a confined area when utilized. Since entropy is about separation, unification between entities decreases, atoms stop communicating as much as they did in closer quarters. Entropy also involves lower frequency. When energy is unified, frequency is higher due to interconnection and communication between energetic entities (such as atoms). Entropy breaks up unification (through natural processes) and this makes the overall frequency of the energy go down. The amount of energy remains the same for a given energy that undergoes entropy, but it attains a lower frequency status. The communication that was present before is a type of energy flow that arises when objects in close proximity interact on a continual basis. With low entropy, communication between entities is high, and this translates to high frequency. With high entropy, communication happens at a slow rate, and therefore frequency is low. In humans, low entropy status (youth) means that fluid memory capacity is high, while in the aged long term committed memories tend to dominate. Since the Universe is moving into a expansive state, and this corresponds with additional entropy, it should follow that the energy of the Universe is shifting into a lower frequency bandwidth, unless this tendency is counteracted by more interconnection between entities, whether at a distance (as with quantum entanglement) or in close proximity. In conclusion, high entropy equals separation and lack of communication. Unification equals low entropy. Connection itself is what determines the amount of entropy present. With connection comes lower entropy. If objects are in communication or not, that is what determines their entropy level. Disorder involves separation and lack of communication. Awareness (and thus consciousness) plays a pivotal part in entropy, because the mind can link together energy and information, or decide to ignore the connections and remain unattuned to them.
That you for this long explanation ... I love the link you made between Entropy increase and space inflation ... it helps me a lot to build a better and deeper understanding ...
The equations of relativity allow things to flow backwards and forwards in time, which makes me think we see entropy because of our prospective of traveling "forward" in time...
Jordan Chessor It allows for them, yes, but things moving forward in time can't ever interact with things moving backward. Maybe I should do a video on Tachyons...
I'm starting to like entropy as it seems to the best argument against evolution. Since we consider the probability of energy spread much higher than energy concentration that we consider as virtually impossible to ever occur, we cannot make an exception for evolution and just say "ok, in this case our washing machine produced folded laundry".
@@this-is-bioman entropy only increases in a closed system. Earth is not a closed system and you get pockets of reduced entropy. Even the formation of the sun, Earth, solar system, galaxy is more ordered (less entropic), so I don't know why you single out evolution..
WOW!, I did well in physics and in particular, thermodynamics, but his "explanations" lost me. I understand ENTROPY. I just didnt understand how he was trying to explain it.
Wanna hear the weirdest thing... I was actually looking at my room which made me think of how I could decrease my entropy by cleaning it. Which made me think of how I heard entropy can only increase. Which lead me to google searching entropy. Which lead me to this video. Which you then asked the question what state of entropy my room was in, to which I must answer the universe has lost track to the order of the energy in my room.
Two things yet to cover: First - the speculation that entropy defines the arrow of time (easy to tell which replay of the mixing fluid is 'correct') Second - in thermodynamics we do try to quantify entropy. It takes energy to reduce entropy so there is a trade-off that must be considered for conservation of energy. Trying to carry his analogy further - it takes energy to organize a messy room (the room may still be messy but more organized) then entropy enters because over time the universe loses track of who expended the energy to organize the room - you or your mom.
I define entropy with a very general phrase "the spreading out". If something hits the ground, its momentum goes into underground vibrations that spread out. If you pee in a swimming pool, your pee won't stay where it is, it will spread out. If you light a baby on fire, the heat doesn't stay where it is, it spreads out. It has to. If heat didn't spread out, then things wouldn't feel hot or cold. Ice wouldn't melt. We could sleep naked on the South Pole and feel fine. To me, entropy just means "the spreading out". Whether it's matter or energy, they all spread out. Entropy is one of those ancient eternal badasses that rule the universe, and as far as I know, the only thing standing against it is another ancient eternal badass: gravity. These two are fighting, and either way, the winner will kill us all. Entropy will freeze us to death in motionless silent darkness, and gravity will crush us into dust and then crush the dust into smaller dust with black holes.
well.. my room was organized chaos.. lol but yes I knew exactly where a specific cord was in the midst of a rats nest. But visually it was causing extreme anxiety! Due partly to the fact that my garage is where I spend 90% of my time . Now that's its clean and "organized"...I do not know where anything specific is.. I would have to ask my wife now.. so how about this, is there such a thing as (and i am not sure if this will make sense or is even if this a word) oxymoronic entropy? idk my A.D.D. has my thiughs going a million miles a sec but I can only keep my train of thought 2-3 words ahead in my mind before I have to stop..look up..spell check and correct..and then look back down at the keyboard and try as hard as I can to remember my train of thought is there such a thing as mental entropy? ty for trying to understand my ramble here.. lol
"It's 'disordered' because the universe itself has lost track of the energy's origins." I was still hopelessly confused up until the moment he said that. Now I think the concept of entropy has clicked for me. (So, it's like, once it's impossible to tell how or even that the Big Bang happened, the universe has reached maximum entropy?)
@@ScienceAsylum But isn't it so that just after the big bang, everything was at extemely high entropy. Everything was a small ball of pure energie. So the big bang itself lowered entropy as the energy formed into stars and galaxies? And then at some point entropy started increasing again?
This video helped me so much!!! How can you explain things and make they seem so simple while the others sources of information make it so complicated? Thank you so much! You helped saving my biophysics final!

Is also same, what I wanna ask is that does universe knowz which photon is which has every photon got something that universe knowz and connects to and that's why it lost track of them. PLZ REPLY P. s. Really helpful video 👍😭👍👍 thnkz
if i have 1 kg water at 25 degree celcius and i add 4.18 kJ heat and its temperature raises to 26 ... can u tell me the entropy change in 2 ststes if the system is isolated.
Why doesn't entropy change when there is work transfer? And is this statement concerning entropy right: The change in entropy represents the maximum amount of work obtainable per degree drop in temperature.
Well, that statement is true SOMETIMES. It's not a universal definition. Entropy is really about statistics of large numbers of molecules. I did a follow-up video: ruclips.net/video/qQhv3YhiJ98/видео.html
So, second (or is it first?) law of thermodynamics states the net change in entropy will always be positive, that is, (I believe) in a close/isolated system. If such is the case, I had a weird question: Do we know if the universe can be definitively classified as a closed/isolated system? I'm curious what the current evidence seems to point to. I assume a closed, isolated system?
Can you explain What's enthalpy?? our teacher did not explaind it in thermodynamics and he gives us only the mathimatical formula ..and i want to know what does it really means
+Manofthewar2016 Heavy Metal The internet definitely does a lot to increase the entropy of the universe because all the servers lose a lot of energy by releasing heat. You might be thinking of "information entropy." Information theory has kind of borrowed the word "entropy" from science, but it means something a little different to them.
Is 2nd law really fundamentle law of universe ,or we just made it according to observations. Because there is no other law suggesting this. Also in water and color example it's just so sooo less likely that color will clump in one place,but still in theory it can happen,we just have to do experiment over & over so many times. So is 2nd law just telling what will most likely happen?
Thanks, Nick! If you feel like it one day, it might be nice to do another entropy video using the “information “ analogy. I’ve seen a couple of those but would really appreciate your take on it.
You say individual atoms do not contain entropy, but what about radioactive decay? And doesn't the universe's maximum entropy affect everything including eventually subatomic particles?
At that point, you're treating the atom as a set of many particles, so you might be able to make an argument for radioactive decay being an example of entropy.... but the subatomic level is _below_ the level we usually discuss entropy.
Fix this for me please: "From the light of the conscious mind comes order out of the darkness of the unconscious mind." I need to be educated on this subject. Much love from a learner.
It's something that allows to predict what should happen when there's a whole bunch of particles in one place. Entropy is something we can calculate very well though if you use probability and statistics. I did a follow-up video on it: ruclips.net/video/qQhv3YhiJ98/видео.html
Think about Entropy in relation to equilibrium. The food coloring example is the best one. Early on the particles are randomly, chaotically mixing, high entropy. Once the mixture settles into equilibrium, well mixed, low entropy. Does that make more sense? In other words, once a change in energy has been introduced, TIME will pass as entropy is lost...
My understanding is that molecules do have mesures of entropy. After all, they do "store" energy in their bonds. They don't really store energy in their bonds, they do the opposite. However, when you compare isomeres, some configurations would have had to release more energy to come about, thereby reducing the accessibility of that energy i.e. increasing entropy.
So we inherently understand entropy and that makes intuitive sense. But what if you subjected a person since birth to a virtual reality playing in reverse? It's unethical, but I would love to know the answer to that hypothetical. Like if you all of a sudden removed them from that virtual reality and back into ours, would they be able to function or adapt? Would they be able to make sense of or predict what's going to happen next that virtual reality? Would it even be possible to construct a virtual reality that had decreasing entropy?
Entropy can be understood as the number of configurations (or “micro states”) of a certain system . By definition S = kB ln (Omega), where omega is the number of micro states. One can understand this omega variable is astronomically large as one has to take a logarithmic expression and scale it to kB to get units comparable to energy dU = TdS - pdV + etc..
You can basically say that there is no way (as of yet) to effectively prevent loss of energy through the transfer and/or transformation process or to be able to effectively capture and store any significant amounts. You can also say that the 1st law of TDs describes the QUANTITY of energy and the 2nd describes the QUALITY of energy.
_"The 1st law of thermodynamics describes the QUANTITY of energy and the 2nd describes the QUALITY of energy."_ I've never heard that before. I like it!
i was wondering about yr analogy and have igot this correct, the rock Doesnt gain entropy just cos its got kinectic energy b4 it falls . . but that leads to this question would the rock have more mass at b4 it fell because of its extra kinectic or potensial energy, soz but im sorta playing catchup wiv yr vids. Also thankz 4answering yestdays question,a big help. rAyZoR.
@@ScienceAsylum yes, not only has the universe's entropy increased in those six years. Also your video skills! 👌🏼 And my abilities as an endurance racer 💪🏼
My brother and I had separate rooms growing up.I kept my room tidy, while my brother's room was untidy. However, this was, my mother's and my opinion. If you asked him for any item; clothing, a book, or anything else he would immediately find it for you.Thus, what was said in the video about what is considered as 'disorder', I perfectly understand, not because I have an understnding of entropy,but simply because I grew up in a certain environment with a sibling who was quite at ease with an apparently messy room.
Great video. Entropy is slightly less confusing to me, which is saying something XD. Uuuuugh it's so abstract. I have a question about the last bit tho. Were you saying that if we didn't see the rock fall, and we just see the resulting energy, there's no clue where that energy came originally came from?
Yes, I was saying that (even though the total amount of energy doesn't change) the universe itself can lose track of where some of it came from. That's one way to look at entropy. The problem with something as abstract as entropy is that there are a lot of ways to look at it.
So...............(shit load of,dots later) can you cause entropy by doing something like this video coz I'm disoriented as hell and discorded and confused
Technically, everything causes entropy to increase ;-) If you're still confused and want to know more though, there is a follow-up video. I put an annotation in this one at the end so people can just click through.
i saw another video that said it’s how spread out the energy in the universe is. Right after the big bang all the energy was compact and in trillions of years the energy will be evenly spread out so when the energy spreads out that’s the entropy increasing
Didn't read all the comments, but I think it's important that at 0:22 you state that we measure energy and momentum, but I think it's important to point out that we can't measure those things. As you've pointed out. Just a slip, but can be confusing.
Perhaps a better term for entropy is the degree of energy dispersion, in which all process in this Earth will eventually have its localized energy dispersed out to its equilibrium state, thus leading to the 'increased' entropy. Eg: Heat energy flows from hot to colder region. Order and disorder term can only be viewed microscopically in terms of the system's energy flow. Perhaps this video can explain more about it: 2nd Law of Thermodynamics & Hydrophobic Sand
Well, "energy dispersion" might work as an explanation in some circumstances, but it's not universal. Entropy can actually go up with energy being dispersed to other locations. It's actually a microscopic probability phenomenon that JUST HAPPENS to SOMETIMES have macroscopic consequences. I made a follow-up video that might explain a little more: ruclips.net/video/qQhv3YhiJ98/видео.html
Are you suggesting that entropy is observational? If entropy is observational does this understanding lead us to a hypothesis that can connect quantum mechanics to general relativity?
I know is very late, several years late, but I got very confused by this video, for the whole reason I got a completely different concept of entropy, maybe I'm remembering a different concept, but an example would go like this: If you mix, let's say water because is an easy example, hot water and cold water (high energy, low energy), assuming same quantities and ignoring environment, entropy would make both to reach the same temperature which would be mid point between former temperatures. Can't remember the description of the concept, but as I know it, I would describe it as the inherent capacity of different things to share energy resulting in both ending with the same amount of energy. So, not seeing any of that on the video, which confuses me, makes me think I'm starting off with a whole different concept, and is driving me crazy
just tell me what you mean by disordered state of energy.. like what's actually an ordered state and... if energy is conserved then why entropy is increasing.. thermodynamics it is but the heat or disordered form of energy is being released into the universe.. it's due to conversions of energies.. and why entropy even exists .. like why every thing always shifts towards disorder.... also a body absorbs heat too.. so does that absorption results in ordered form of energy..... and if that then whats the relation between internal energy and entropy
My engineering thermodynamics prof described entropy as ‘uniformity’...in other words tending toward the lowest energy state. I don’t really ever hear it described that way by others, but it seems to make sense. In that understanding, entropy is really a driving force in the universe, doing useful work as energy moves from high organization to the uniformity of the lowest energy state. It’s oddly counterintuitive to say that entropy is increasing when going to a lower state, though.
The first time I heard of entropy was from the anime Mahō Shōjo Madoka Magika. There it was described as the difference between the heat neded to grow a forest and the heat produced by burning that forest. And you come to tell that it is in fact the value of the agregate state in which a thermodinamic object is. Now I feel that the entropy tends to a maximum and that it can only be created and not destroyed because the entropy is in fact the cumulation of the momentum and the total sum of the energy vectors whithin an obect, in other words the destruction itself that takes place within a system. So you can not destroy it since that would mean the vanishing of energy; and since the energy must be conserved, the entropy can not be destroyed. Anyway, still do not get what that methaphor about the forest was refering to.
Energy remains in a state of limbo. It is neither created nor destroyed. Energy has always existed and will continue to do so forever. Much like the term God.
Thank you very much for this. I often grieve my scientific illiteracy. I came here because I used the word 'entropy' in a song, and wanted to make sure it actually made sense. The line reads "Every resolve I ever made has fallen into deep entropy; they never stand, they never stay, on shifting sands I build this house of clay." I think it works (poetically) especially regarding what you said about the messy room analogy. Does '*deep* entropy' make sense? I don't know... I'd be open to changing it, at your recommendation. Thanks!
In music, you get an artist license. There's a lot of nuance with the word "entropy," but I think you're correct _enough_ that you won't be misleading anyone.

@@fabricekahn2815 You are welcome. Hope my theory was helpful.
The equations of relativity allow things to flow backwards and forwards in time, which makes me think we see entropy because of our prospective of traveling "forward" in time...
Jordan Chessor It allows for them, yes, but things moving forward in time can't ever interact with things moving backward. Maybe I should do a video on Tachyons...
***** Yes, please.

Weirdly enough, that was the best explanation for entropy I've heard.
I'm starting to like entropy as it seems to the best argument against evolution. Since we consider the probability of energy spread much higher than energy concentration that we consider as virtually impossible to ever occur, we cannot make an exception for evolution and just say "ok, in this case our washing machine produced folded laundry".
👍
@@this-is-bioman entropy only increases in a closed system. Earth is not a closed system and you get pockets of reduced entropy. Even the formation of the sun, Earth, solar system, galaxy is more ordered (less entropic), so I don't know why you single out evolution..
@vincechittenden Evolution is a delusion and every argument against it, is a good one.
WOW!, I did well in physics and in particular, thermodynamics, but his "explanations" lost me.
I understand ENTROPY.
I just didnt understand how he was trying to explain it.
michael allen lol, I know what u mean
Right? The explanation made me feel like I was on acid
Sir could I use some part of your video clip for educating students physics in Bangla language?
Wanna hear the weirdest thing... I was actually looking at my room which made me think of how I could decrease my entropy by cleaning it. Which made me think of how I heard entropy can only increase. Which lead me to google searching entropy. Which lead me to this video. Which you then asked the question what state of entropy my room was in, to which I must answer the universe has lost track to the order of the energy in my room.
Full circle.
***** Yes, I am not what, I am how.
Two things yet to cover: First - the speculation that entropy defines the arrow of time (easy to tell which replay of the mixing fluid is 'correct')
Second - in thermodynamics we do try to quantify entropy. It takes energy to reduce entropy so there is a trade-off that must be considered for conservation of energy. Trying to carry his analogy further - it takes energy to organize a messy room (the room may still be messy but more organized) then entropy enters because over time the universe loses track of who expended the energy to organize the room - you or your mom.
I define entropy with a very general phrase "the spreading out".
If something hits the ground, its momentum goes into underground vibrations that spread out.
If you pee in a swimming pool, your pee won't stay where it is, it will spread out.
If you light a baby on fire, the heat doesn't stay where it is, it spreads out. It has to. If heat didn't spread out, then things wouldn't feel hot or cold. Ice wouldn't melt. We could sleep naked on the South Pole and feel fine.
To me, entropy just means "the spreading out". Whether it's matter or energy, they all spread out. Entropy is one of those ancient eternal badasses that rule the universe, and as far as I know, the only thing standing against it is another ancient eternal badass: gravity.
These two are fighting, and either way, the winner will kill us all. Entropy will freeze us to death in motionless silent darkness, and gravity will crush us into dust and then crush the dust into smaller dust with black holes.

well.. my room was organized chaos.. lol but yes I knew exactly where a specific cord was in the midst of a rats nest. But visually it was causing extreme anxiety! Due partly to the fact that my garage is where I spend 90% of my time . Now that's its clean and "organized"...I do not know where anything specific is.. I would have to ask my wife now.. so how about this, is there such a thing as (and i am not sure if this will make sense or is even if this a word) oxymoronic entropy? idk my A.D.D. has my thiughs going a million miles a sec but I can only keep my train of thought 2-3 words ahead in my mind before I have to stop..look up..spell check and correct..and then look back down at the keyboard and try as hard as I can to remember my train of thought is there such a thing as mental entropy? ty for trying to understand my ramble here.. lol
"It's 'disordered' because the universe itself has lost track of the energy's origins."
I was still hopelessly confused up until the moment he said that. Now I think the concept of entropy has clicked for me.
(So, it's like, once it's impossible to tell how or even that the Big Bang happened, the universe has reached maximum entropy?)
Pretty much. At that point, everything is random and nothing significant will be happening any more.
@@ScienceAsylum But isn't it so that just after the big bang, everything was at extemely high entropy. Everything was a small ball of pure energie. So the big bang itself lowered entropy as the energy formed into stars and galaxies? And then at some point entropy started increasing again?

if i have 1 kg water at 25 degree celcius and i add 4.18 kJ heat and its temperature raises to 26 ... can u tell me the entropy change in 2 ststes if the system is isolated.
That was actually quite informative. Well explained.
Why doesn't entropy change when there is work transfer?
And is this statement concerning entropy right: The change in entropy represents the maximum amount of work obtainable per degree drop in temperature.
Well, that statement is true SOMETIMES. It's not a universal definition. Entropy is really about statistics of large numbers of molecules. I did a follow-up video: ruclips.net/video/qQhv3YhiJ98/видео.html
I thought this guy was kane from wwe !!!!!

@@ngoziokuboyejo3133 thank you for your kind words!! I'm offended!! LOL
So, second (or is it first?) law of thermodynamics states the net change in entropy will always be positive, that is, (I believe) in a close/isolated system. If such is the case, I had a weird question:
Do we know if the universe can be definitively classified as a closed/isolated system? I'm curious what the current evidence seems to point to. I assume a closed, isolated system?
I assume definition of closed vs open system refers to whether energy is able to flow freely in or out of said system*
Meaning. . .if net change in energy over a large period of time is indeed zero. . .strong evidence that universe is an isolated system?
It's the second law of thermodynamics. I did a follow-up video: ruclips.net/video/qQhv3YhiJ98/видео.html

a question: internet is an example of entropy? (entropy is a term used in termodynamic, but just to undersyand the overall concept)
+Manofthewar2016 Heavy Metal
The internet definitely does a lot to increase the entropy of the universe because all the servers lose a lot of energy by releasing heat. You might be thinking of "information entropy." Information theory has kind of borrowed the word "entropy" from science, but it means something a little different to them.
you have a great sense of humour sir
Is 2nd law really fundamentle law of universe ,or we just made it according to observations. Because there is no other law suggesting this. Also in water and color example it's just so sooo less likely that color will clump in one place,but still in theory it can happen,we just have to do experiment over & over so many times.
So is 2nd law just telling what will most likely happen?

You say individual atoms do not contain entropy, but what about radioactive decay? And doesn't the universe's maximum entropy affect everything including eventually subatomic particles?
At that point, you're treating the atom as a set of many particles, so you might be able to make an argument for radioactive decay being an example of entropy.... but the subatomic level is _below_ the level we usually discuss entropy.
Organized Chaos.

"From the light of the conscious mind comes order out of the darkness of the unconscious mind."

Much love from a learner.
Shut up.
so entropy is a constantly climbing analogy for what has happened to matter of a certain size?
It's something that allows to predict what should happen when there's a whole bunch of particles in one place. Entropy is something we can calculate very well though if you use probability and statistics. I did a follow-up video on it: ruclips.net/video/qQhv3YhiJ98/видео.html
4:10 spelled chaos wrong. irony :)
TheSageCommander
Lol saw that ams I was looking for someone to comment that.
Think about Entropy in relation to equilibrium. The food coloring example is the best one. Early on the particles are randomly, chaotically mixing, high entropy. Once the mixture settles into equilibrium, well mixed, low entropy. Does that make more sense? In other words, once a change in energy has been introduced, TIME will pass as entropy is lost...
I did a follow-up video: ruclips.net/video/qQhv3YhiJ98/видео.html
Toooo enthusiastic.
My understanding is that molecules do have mesures of entropy. After all, they do "store" energy in their bonds.
They don't really store energy in their bonds, they do the opposite. However, when you compare isomeres, some configurations would have had to release more energy to come about, thereby reducing the accessibility of that energy i.e. increasing entropy.
that clock backside is awwwsm n vedio too !!!
Universe loses track? But information is never lost? Can you reconcile these?

+Sreerag blame entropy.
So we inherently understand entropy and that makes intuitive sense. But what if you subjected a person since birth to a virtual reality playing in reverse? It's unethical, but I would love to know the answer to that hypothetical. Like if you all of a sudden removed them from that virtual reality and back into ours, would they be able to function or adapt? Would they be able to make sense of or predict what's going to happen next that virtual reality? Would it even be possible to construct a virtual reality that had decreasing entropy?
entropy is the measurement of chaos in a system.
sikholiwe nxazonke But then what is chaos?
Entropy can be understood as the number of configurations (or “micro states”) of a certain system . By definition S = kB ln (Omega), where omega is the number of micro states. One can understand this omega variable is astronomically large as one has to take a logarithmic expression and scale it to kB to get units comparable to energy dU = TdS - pdV + etc..

"super zoom" buahhahahahahhahahahahah
You can basically say that there is no way (as of yet) to effectively prevent loss of energy through the transfer and/or transformation process or to be able to effectively capture and store any significant amounts. You can also say that the 1st law of TDs describes the QUANTITY of energy and the 2nd describes the QUALITY of energy.
_"The 1st law of thermodynamics describes the QUANTITY of energy and the 2nd describes the QUALITY of energy."_
I've never heard that before. I like it!
good explanation and funny too :) thanks
elocin sel You're welcome! :-)
Actually it was a very poor andalusia incorrect explanation.
i was wondering about yr analogy and have igot this correct, the rock Doesnt gain entropy just cos its got kinectic energy b4 it falls . . but that leads to this question would the rock have more mass at b4 it fell because of its extra kinectic or potensial energy, soz but im sorta playing catchup wiv yr vids. Also thankz 4answering yestdays question,a big help. rAyZoR.
Less energy means less mass, so if it loses energy to the environment on the way down, then it loses mass too.
Clicking on this video was the worst decision of my life. Just wasted 5 precious minutes...
I'm watching this in 2019. There's soooo much difference compared to Nick's current video's.

@@ScienceAsylum yes, not only has the universe's entropy increased in those six years. Also your video skills! 👌🏼 And my abilities as an endurance racer 💪🏼
My brother and I had separate rooms growing up.I kept my room tidy, while my brother's room was untidy. However, this was, my mother's and my opinion. If you asked him for any item; clothing, a book, or anything else he would immediately find it for you.Thus, what was said in the video about what is considered as 'disorder', I perfectly understand, not because I have an understnding of entropy,but simply because I grew up in a certain environment with a sibling who was quite at ease with an apparently messy room.
Great video. Entropy is slightly less confusing to me, which is saying something XD. Uuuuugh it's so abstract. I have a question about the last bit tho. Were you saying that if we didn't see the rock fall, and we just see the resulting energy, there's no clue where that energy came originally came from?
Yes, I was saying that (even though the total amount of energy doesn't change) the universe itself can lose track of where some of it came from. That's one way to look at entropy. The problem with something as abstract as entropy is that there are a lot of ways to look at it.
So...............(shit load of,dots later) can you cause entropy by doing something like this video coz I'm disoriented as hell and discorded and confused
Technically, everything causes entropy to increase ;-) If you're still confused and want to know more though, there is a follow-up video. I put an annotation in this one at the end so people can just click through.
*****
_"Technically, everything causes entropy to increase"_
Wrong.
Great explanation but just one question. So what exactly is entropy?
i saw another video that said it’s how spread out the energy in the universe is. Right after the big bang all the energy was compact and in trillions of years the energy will be evenly spread out so when the energy spreads out that’s the entropy increasing
Didn't read all the comments, but I think it's important that at 0:22 you state that we measure energy and momentum, but I think it's important to point out that we can't measure those things. As you've pointed out. Just a slip, but can be confusing.
You are correct. Technically speaking, we measure things like position and velocity, then we _infer_ things like energy and momentum.
So by "the universe not knowing" you mean quantum mechanics (with a hypothetical reverse time arrow)?
can you tell something about enthaly??
Perhaps a better term for entropy is the degree of energy dispersion, in which all process in this Earth will eventually have its localized energy dispersed out to its equilibrium state, thus leading to the 'increased' entropy. Eg: Heat energy flows from hot to colder region. Order and disorder term can only be viewed microscopically in terms of the system's energy flow. Perhaps this video can explain more about it: 2nd Law of Thermodynamics & Hydrophobic Sand
Well, "energy dispersion" might work as an explanation in some circumstances, but it's not universal. Entropy can actually go up with energy being dispersed to other locations. It's actually a microscopic probability phenomenon that JUST HAPPENS to SOMETIMES have macroscopic consequences. I made a follow-up video that might explain a little more: ruclips.net/video/qQhv3YhiJ98/видео.html
just started to get some more idea about the concept. but still don't know how to quantify entropy
James Huang My follow-up video might help. ruclips.net/video/qQhv3YhiJ98/видео.html
Are you suggesting that entropy is observational? If entropy is observational does this understanding lead us to a hypothesis that can connect quantum mechanics to general relativity?
I know is very late, several years late, but I got very confused by this video, for the whole reason I got a completely different concept of entropy, maybe I'm remembering a different concept, but an example would go like this:
If you mix, let's say water because is an easy example, hot water and cold water (high energy, low energy), assuming same quantities and ignoring environment, entropy would make both to reach the same temperature which would be mid point between former temperatures.
Can't remember the description of the concept, but as I know it, I would describe it as the inherent capacity of different things to share energy resulting in both ending with the same amount of energy.
So, not seeing any of that on the video, which confuses me, makes me think I'm starting off with a whole different concept, and is driving me crazy
just tell me what you mean by disordered state of energy.. like what's actually an ordered state and... if energy is conserved then why entropy is increasing.. thermodynamics it is but the heat or disordered form of energy is being released into the universe.. it's due to conversions of energies.. and why entropy even exists .. like why every thing always shifts towards disorder.... also a body absorbs heat too.. so does that absorption results in ordered form of energy..... and if that then whats the relation between internal energy and entropy
This might help: ruclips.net/video/qQhv3YhiJ98/видео.html
But energy can not be created or destroyed so while throwing stone where the energy goes?
Into the surrounding environment (mostly as heat)
Cool video! Those super zoom thing is a nice touch btw
Thanks!
My engineering thermodynamics prof described entropy as ‘uniformity’...in other words tending toward the lowest energy state. I don’t really ever hear it described that way by others, but it seems to make sense. In that understanding, entropy is really a driving force in the universe, doing useful work as energy moves from high organization to the uniformity of the lowest energy state. It’s oddly counterintuitive to say that entropy is increasing when going to a lower state, though.
I did a follow-up video that goes into a little more detail about how probability/statistics fits into this: ruclips.net/video/qQhv3YhiJ98/видео.html
The first time I heard of entropy was from the anime Mahō Shōjo Madoka Magika.
There it was described as the difference between the heat neded to grow a forest and the heat produced by burning that forest.
And you come to tell that it is in fact the value of the agregate state in which a thermodinamic object is.
Now I feel that the entropy tends to a maximum and that it can only be created and not destroyed because the entropy is in fact the cumulation of the momentum and the total sum of the energy vectors whithin an obect, in other words the destruction itself that takes place within a system. So you can not destroy it since that would mean the vanishing of energy; and since the energy must be conserved, the entropy can not be destroyed.
Anyway, still do not get what that methaphor about the forest was refering to.
Energy remains in a state of limbo. It is neither created nor destroyed. Energy has always existed and will continue to do so forever. Much like the term God.
Thank you very much for this. I often grieve my scientific illiteracy. I came here because I used the word 'entropy' in a song, and wanted to make sure it actually made sense. The line reads "Every resolve I ever made has fallen into deep entropy; they never stand, they never stay, on shifting sands I build this house of clay." I think it works (poetically) especially regarding what you said about the messy room analogy. Does '*deep* entropy' make sense? I don't know... I'd be open to changing it, at your recommendation. Thanks!
