In the 30 years I have been studying physics, this is absolutely the CLEAREST explanation of entropy I have ever seen. Great job Higgsino. (Fun Fact: I was taught by a student of Higgs -kind of like my academic granddad, lol).
Good TH-cam on demonstrating entropy. This is the way I try to explain entropy. The quantity (or amount) of energy in a closed system which could be the universe is constant but it is always changing (or “transforming”) so that it becomes less concentrated and more diluted. The reason I say “transforming” is because the word entropy comes from the Greek word for transformation which is pronounced “metamorphocy”. The Greek word was combined with energy and entropy was used. As the energy becomes more and more diluted there will be many states along the way that will appear to be stable or in equilibrium but these stable states are still diluting (we can also say decaying). It is just that they could be diluting at an extremely low rate that is barely detectible giving the appearance of stability or equilibrium. The more diluted the energy of the closed system becomes, the lower the temperature will be. The temperature can get close to absolute zero but never reach absolute zero. So if you divided the amount of energy in the closed system by the change in temperature for any given time period, the result will always be positive and as time increases the result will also increase. This result is what entropy is (Entropy = Energy / Temperature). So saying that entropy is always increasing is equivalent to saying that the energy in a closed system which could also be the universe is always diluting or decaying and becoming less concentrated.
Based on this behavior. The Cosmo's essentially only needs differentials in positive and negative states with-in certain mediums: it actually only seems natural that this must be commonly present all around our environment. Probably in tons of ways we don't even see or realize. Electrons are everywhere, differences in charges & states must be as common as the presence of hot and cold temperatures which cause places with high or lower pressure area's. Which causes wind, air movement, flow. This behavior in nature is key: nature seems to need a state of higher energy and a state of lower energy to create some form of fundamental aspect of functions with-in Nature. With those differences, nature finds ways to utilize it, which allows us to have functional system's, which eventually get themselves self back to a more stable ground state. ~Differences~ or *fluctuations seems to be the core behavior of nature's "engine" to any given system in nature as we know it. This is really facinating to ponder about. Additionally, I once thought space was a complete vacuum. I saw something saying it's not a "complete vacuum" which is interesting. That seems to be just enough that it allows certain things and behaviors to occur throughout the Cosmo's. Which then seems to be the core backbone to most fundamental forces of nature. It strives to reach that stable ground state BUT it is capable of having areas of differentials. Those differences are the starter factor that gets most things rolling rather than staying static/stable or flat out inactive.
There is a problem with this.. Entropy has no units.. even J/K is only a pseudo unit because K is a temperature which is energy per molecule. So using E for energy J/K = E/T = E/E/N = N (number of molecules) ie its just a number as R Feynmann would teach in his classes on entropy. In fact you can replace k with 1 and use log of any base (10, e, 2) and s = log (W) is still a valid entropy. The real problem here is the failure to define ORDER..
Just subscribed having watched back-to-back this video and your video on tides. Both concepts I understood well however both your videos still provided me with a clearer understanding. Already two out of the two videos of yours I've watched have provided me with the clearest picture of their subject matter. Thanks.
Take the Univers as a space filled with moving particles. At the moment of Big Bang these particles had a specific configuration, each of them having a specific position and from then on they will have all the configurations possible. Imagine the movement of these particles as a fastforward movie that you can stop at any moment and any time you stop it they have a specific configuration. That's a microstate. Move a particle 1cm further and that's another microstate; move it a little bit further and that's another microstate (you get the idea). Now comes the fun part: lets suppose that you have maximum of 100 000 possible microstates. It follows that every single microstate has the same probability since any microstate is 1 in 100 000. But that sounds wrong doesn't it? I mean, that sounds like the Univers does not have any trend in the configuration of its particles. Not really. Because different groups of these microstates correspondes to a Macrostate or another. A Macrostate is characterised by a certain Temperature, Pressure etc. For example a Macrostate in which the Univers has a general low Temperature is one in which the particles are evenly spread out, and one in which the Univers has a general low temperature but a few pockets of high temperature is one in which fast moving particles are concentrated in some specific places. And since there are more configurations of evenly/ unorderly spread particles there are more Microstates corresponding to the Low Temperature Univers so that type of Macrostate is more probable. Simply put, from the all the Microstates possible this many correspond to a low temp Univers/ low temp Macrostate and this many correspond to a Univers with a few places of high concentrated energy. It doesn't matter the specific configuration of any individual particle of your Microstate, if it's one in which they are evenly spred that will corespond to a General Low Temperature Macrostate. So being the fact that from 100 000 possible microstates, 60 000 correspond to a evenly spred/low temp Macrostate if your Univers started from a ordered configuration it will become with time a disordered one.
Some great animations there. I've enjoyed this video a lot and really enjoyed the glass analogy; it definitely shattered my own idea of "order vs disorder". So would it be more accurate to say entropy is basically reaching a sort of equilibrium where it is less likely to get out of it than to get back to that equilibrium? For example, with the atoms in the box, the equilibrium is 50-50, and any change would create lower entropy which means the system naturally balances back to higher entropy (ie 50-50)?
This is Barris! - French History yes exactly - it will always fluctuate around evenly distributed numbers on each side. In real world examples systems contains billions of billions of atoms so one side can suddenly be in a state where the side have millions more atoms on one side but it’s still more or less evenly distributed
heat only flows in one direction......so if we encountered a situation where heat flowed from cold to hot then what would we conclude? that there must be some contravention to the laws of nature caused by an external agency........for example, how do we account for the human organism? a highly ordered information rich object that compels heat into itself by absorbing the remnant heat in cold objects which it then uses to enhance and increase its own order.....the implication of this reversal of the laws of thermodynamics by an external agency of some kind taken to the nth recursion strongly suggests a proof of the existance of a higher power (or God if you prefer that terminology)

@@Higgsinophysics I'm glad to hear that. One more concept I believe I've understood. Thank you!
Great video subbed!
Is that the natural log in that equation ?
Great video!
Loving the animations
Thank you!
Very nice material. I love the 3d animations, from the logo to the explanatory ones. What software do you use to do them?
Thank you! Any 3d software will do. I can recommend Blender and cinema 4d
Awesome video, surprised you don't got more subs
haha maybe one day
thanks for giving information.
please do video about gibbs free energy
That music sounded like nujabes/samurai champloo. Is it that or some unknown chillhop?
for me it's unkown lol - I cant remember where I found it, I named the song "bg-music" and there is no meta-data..
heat only flows in one direction......so if we encountered a situation where heat flowed from cold to hot then what would we conclude? that there must be some contravention to the laws of nature caused by an external agency........for example, how do we account for the human organism? a highly ordered information rich object that compels heat into itself by absorbing the remnant heat in cold objects which it then uses to enhance and increase its own order.....the implication of this reversal of the laws of thermodynamics by an external agency of some kind taken to the nth recursion strongly suggests a proof of the existance of a higher power (or God if you prefer that terminology)
neat
Lucid!
Why everything wants to get stability in this universe
drunk. can't do it right now.
Shouldn't the title be "why heat flows from hot to cold systems"
oh my god yes thank you! I recently changed the title, and my brain must have been offline. Thank you.
Cant understand you
there are english subtitles
@@Higgsinophysics I could understand you very well :)
@@r_____________________ glad to hear that !
Wait this wasn’t so hard. I understand it. I think.🤔
Glad you think that. That's was the goal at least.
