- Entropy is a very weird and misunderstood quantity. Hopefully, this video can shed some light on the "disorder" we find ourselves in...

If you're still confused, try watching my follow-up video: "Why Does Entropy Even Matter?" th-cam.com/video/qQhv3YhiJ98/w-d-xo.html
i am confused: why won't my wife let me get a bed shaped like a race car?
Finally, I know who I am . . . I am . . .tum tum ta da . . . Emergent Property!!!

You meant "Organized C H A O S " right ? (Not organized c h o a s)
I just saw the follow up video. I didn't watch it. But it was there.
My room is best described as a black hole, once i lose something it's gone forever
Then your room must be the universe
Take “everything” out of your room door one-by-one until you find that lost thing. I’m sure you will find.
elPichirri whatever goes in never get out hahaha
like socks and nerf balls
😂
That last part. "It's like the universe has a witness protection program for its energy and we call it entropy."
I think that's the best description of entropy I ever heard 😄
Please can you explain me, what's the meaning of this ?
Nice try, Still don't know what the hell your taking about.
why would he make the video if he didn't know and love the subject? you can complain that he didn't express it in a way you understand, but not that he doesn't know it. it seems to me you're the only one who doesn't know what he's talking about.
+Desmond Bear I believe he is talking for himself, not for the maker of the video. I also found it interesting and entertaining but not especially helpful.
taqunuzuqu ququ oooh that's true its ambiguous. Interesting wordplay, even though it was unintentional :)
I understood it. At the end of the dispersion of the colour in the liquid it would be impossible to trace where it was first added, so you could say the dispersion was entropic... I think.
Same.
Your videos are amazing. I am completing my bachelor's degree in physics and to me the hardest thing to reading/studying physics is how to comprehend/visualize the meanings through simple explanations. If you truly understand a concept, teaching it with simple means with enthusiasm and humor, makes it so much more enjoyable as well. Knowing the math is great and all but understanding the meaning is what physics and your explanations brilliant.
Thanks!
I'm still confused....
Follow-up video! th-cam.com/video/qQhv3YhiJ98/w-d-xo.html ...your comment made an appearance :-)
So your brain has got high entropy :)
Easy way to get into "entropy" understanding is the level of hidden information.
yaa me too
th-cam.com/video/870y6GUKbwc/w-d-xo.html
To understand the subject you need to think in terms of:
- Emergent property
- Energy status (chaotic vs ordered or condensed)
I am satisfied with the explanation. Thanks

I've been watching a LOT of The Science Asylum this week, and this is the earliest video of you I've seen. Pretty cool to see how far your production quality has gone up from an already great start.
Thanks! This one is soooo old 🤦♂️
I like to think of entropy as the universe’s persistent pursuit of a smooth and uniform state.
Superb video - my first one of yours. Love your attitude, your pace, explanations, visual aids and more. Prior to this one I watched the beginnings of a few others (on entropy) and yours is by far the best. I was hooked for the full 5 minutes, and as much as entropy was trying it was unable to divert my attention.
*_the word "high entropy" can't describe how much chaos in my room_*
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.
It is probably a show for kids and youngsters, but I always end up on this channel when I need to better understand physics concepts and laws. Because they say that when you understand enough in a subject to explain to a 5-year-old, then you are a good teacher! Thank you, Science Asylum! Lol
My intended audience has always been adults. I just feel like that's no reason to be boring. Science education can be fun for adults too 🤓
@@ScienceAsylum Cool! But I am convinced you also have a crowd of little budding genius. Have a good day and keep on the fun videos about science!
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.
felynecomrade Depressing... but accurate.
***** it proves that nothing is for us.
:)
Wow! Thanks! ^_^
Not bad.
What is Entropy? It's a greatly misunderstood measurement having every day consequences. Watch to learn more!
+The Science Asylum Nice video, I wish I kan say I got it :) Reading the book "Hyperion cantos" where anti entropic fields cause a time lapse i a area, so here I am. Maybe the language barrier adds to the confusion.
*****
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: th-cam.com/video/qQhv3YhiJ98/w-d-xo.html
I know, we must ask Dr. Who, which ever one of them is around, about this!
spiritual entropy
Ok men great video good work if you mind you can talk a little slower but it's ok it's sour a great work so congratulations about it
I see it this way, the word Chaos had a highly intentional entropy
I truly love your videos!! Each one makes me a little bit crazier!!
My room is definitely a low energy room. I like things to be really organized, and to look like that too. =)
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.
What is Physical Information? th-cam.com/video/or8Rktj_HA4/w-d-xo.html
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.
I thought this guy was kane from wwe !!!!!
yes amazing resemblance

Hahaha
@@ngoziokuboyejo3133 thank you for your kind words!! I'm offended!! LOL
that final bit on entropy was millions to one
rudolph clausius? i know that's you santa pick a better alias!
That was actually quite informative. Well explained.
"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?
I'm really surprised.. you did an absolutely excellent job explaining the reality of what entropy is.
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!
+Eduarda Barros
Yay :-) I'm glad it helped!

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.

...and, yet, here you are... pondering the abyss.
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

Great video. Nice breakdown to a very difficult concept. Thank you!!
Weirdly enough, that was the best explanation for entropy I've heard.
High levels of entropy, now my universe makes sense. I am doomed.
one of the my favorite channel
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.
Nick - it seems to me that you have given entropy and similar abstract topics a great deal of thought. This takes great focus. Similar to Einstein in that he was renown for his intensity of focus perhaps? I wish I had the same focus.
you have a great sense of humour sir
Damn, I lost it at "witness protection program" :D
Congratulations‼️ Super cool material. 👍
I gotta say you improved a lot. These earlier videos are not so clear as the new ones
Thanks :-) I'm a work in progress.
Just keep on doing this for the sake of us. You are amazing :)
Loved the video, don't take me wrong... but did any one notice he misspelled Chaos?? 🤨
Dilean Perdomo not a misspelling, that’s entropy in a actionn😎
How accurately are the songs unsustainable and isolated system off the Muse album The 2nd Law which was named after the second law of thermodynamics.
Alex Leonard The lyrics are pretty accurate actually.
Alex Leonard Also, I'm a Muse fan, so this comment was awesome.
My room?
:))
I can't find my phone even if I was holding it a minute ago. Remember all those white and black dots on old TV's when there was no signal?
very cool that entropy is "emergent" - thanks Nick!!!
Omg I need that clock in my room
Think geek has it.
hey Nick I found a way to really enjoy my LUCID dreams... awesome
Lucid is probably a pseudonym.
also love your old video, full knowledge
Great video dude. Keep it up!
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
Lol still dont understand but ill keep looking around. Nice vid though lol.
Marc-Anthony Pabon There's a follow-up video: th-cam.com/video/qQhv3YhiJ98/w-d-xo.html
Awesome, thanks.
Cool video! Those super zoom thing is a nice touch btw
Thanks!
I would explain it like this….
The moment we (conscious awareness and emergent property) becomes aware of having lost the origin of the energy of particles we may classify them as “chaotic” and simultaneously gain the “emergent property” that is our ability to measure the degree of disorder of the energy in the whole…
No one knows how I do it but my room is a blizzard, but, I know where everything is. :)
:)
Organized Chaos.
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.
Shut up.
Wow! Amazing explanation. Thank you!
Witness protection program… you are a pure genius…
that clock backside is awwwsm n vedio too !!!
I got into a fight with a cheese grater
Are ya winning son
Universe loses track? But information is never lost? Can you reconcile these?
Mom: clean your room it's so chaotic
Me: no need mom, it is organized chaos
Toooo enthusiastic.
4:10 spelled chaos wrong. irony :)
TheSageCommander
Lol saw that ams I was looking for someone to comment that.
I'd explain entropy as "The energy of the universe tends towards being evenly spread everywhere (Equilibrium, if you may)." As in, Heat Death of the Universe.
It doesn't really have anything to do with chaos, randomness, or order, or any other silly distracting words used to describe it.
Very low entropy in my room! Great video -Thank you !
increase entropy on my mind while watching u r video😕😕😕😨😨😨
I think u r the first person to use 'u r' incorrectly....
+Sreerag blame entropy.
entropy is the measurement of chaos in a system.
sikholiwe nxazonke But then what is chaos?
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.
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".
"super zoom" buahhahahahahhahahahahah
Clicking on this video was the worst decision of my life. Just wasted 5 precious minutes...
love your explanation!
Could "OUT"tropy be a good candidate for the conceptual opposite on "IN"tropy or Entropy?
good explanation and funny too :) thanks
elocin sel You're welcome! :-)
Actually it was a very poor andalusia incorrect explanation.
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: th-cam.com/video/qQhv3YhiJ98/w-d-xo.html
So the energy in any isolated system will ALWAYS tend towards chaos (higher entropy).
Okay I think I finally got this one!
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
My sock drawer is brimming with entropy!
Very interesting video - but I have to say... is there a baby in the clothes hamper at 4:07? That really IS a chaotic room
can you tell something about enthaly??
My room looks like a room with more entropy than there is matter there...
Great job! You explained entropy well. 👊🏿... Thank you!
You're welcome! Glad you liked it!
Unfortunately the explanation was incorrect.
0:55 looking like a bootleg Abe Lincoln
My bedroom is very low-entropy because I can't sleep unless things are neat and tidy around me. Unfortunately, I can't say the same for the other rooms in my house! I'm working on it though.
Dude thanks for the low entropic pedagogy! awesome!
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: th-cam.com/video/qQhv3YhiJ98/w-d-xo.html
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.
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 ...
@@fabricekahn2815 You are welcome. Hope my theory was helpful.
Don't forget about enthalpy. Disorder to order. Good job I like your videos.

This is top notch. Thank you!
I'm watching this in 2019. There's soooo much difference compared to Nick's current video's.
Yeah... I've learned a lot....
@@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 💪🏼

Nice man :) ... I really admire your way of presentation of science ^_^
+Ali AL-N Thanks!
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.
@@ScienceAsylum Legend. God bless you.
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!
Entropy complicates resolve because a System is: gossipy/(sensitive: susceptible). Discipline focuses design upon Resolve SO you do NOT have to talk about it, and can enjoy more snuggle time with your own System. Discipline begins by recognizing what is Relevantly significant to YOUR system. The tendency to make that unique to YOUR system modalizes design into unique but synergistic function or purpose.
Nice explanation.
As a rule your videos are wonderfully enlightening. This one is an exception. I think it would be more helpful to define entropy in terms of the amount of information required to define a system.
This is a _very_ old video back before I really figured out this whole YT thing. I did a better job in later videos:
