The best and most underrated science channel, hands down. This channel doesn't need huge explanation, tons of formulas and images. A simple sentences and simple images, so a 10 year old can understand it, which means he has mastered it to incredible degree. If there were more physics teachers like this guy, I am sure that there will be more people interested in physics. Nothing I can say more, keep up the good work and stay safe mate, you are a diamond.

The best way to describe entropy is that the universe is slowly but surely grinding down and erasing all traces of us humans ever having existed

This might be the best (or at least most intuitive) explanation of entropy. Literally all other KZread channels just say that entropy is a measure of disorder without explaining how to measure disorder. I mean, there is no disorder-o-meter. But here the "measure of disorder" was explained as the probability of a family of similar arrangements. Great video :)

@TheParadoxOfParadox

2 жыл бұрын

It seems as though this explanation presupposes some meaningful notion of familiarity and disfamiliarity on the level of emergent objects (like apples). We can only notice that some arrangements of fundamental particles are arranged 'apple-wise' if the emergent property of 'being an apple' is already a distinguished state (i.e. a 'non-random' state). But seemingly, in asking about the nature of entropy we're really wanting to ask about the nature of all things in our universe, not just those for which there is a predefined meaning to us. So our explanation requires more explaining. Carlo Rovelli gave an interesting talk (on YT) to the Royal Institute on 'The Physics and Philosophy of Time', where he pointed out that if we had an arrangement of blue and red balls in a box, and separated them by colour (blue on the left, red on the right, say), the box would seem to have low-entropy. But if we became sensitive to minute variations in size, the box of balls would in fact 'all of a sudden' look extremely homogenous (given we only sorted by colour, and not by size; they are 'sorted' with respect to colour, but 'unsorted' with respect to size). It seems to me as though the idea of entropy requires an additional point of reference to be meaningful. I am yet to have this fully click for me (though this channel surely explained more than most others!).

@Cubinator73

@@TheParadoxOfParadox That is certainly an interesting detail I haven't yet thought about. The thing is we have multiple rigorous definitions of entropy, which are independent of our perception or whether we give names to some groups of arrangements and not to others. You can blindly apply those definitions without having to know why they are defined the way they are. The problem is intuitively explaining what those definitions mean. And when using the probability of groups of arrangements as the intuition of what entropy is, it is certainly easier to imagine an apple being a less likely arrangement of particles than a homogeneous cloud of particles. But we don't have to use an apple for this comparison. We could instead talk about abstract density distributions of the cloud of particles. Density distributions with spikes or with two or more regions of different densities are intuitively less likely than a constant density distribution, because the former always evolves into the latter. Now we have an intuitive (to me) picture of entropy that is independent of our perception and whether we give a name to certain arrangements. We can even go one step further and declare two distributions "similar", if their difference is sufficiently small. How small? Well, that will depend on what kinds of distributions we want to distinguish (e.g. apples and homogeneous clouds).

A minor critique regarding the balloon example (6:39): Picking a balloon instead of a rigid container (eg an open bottle) makes the whole situation needlessly complicated and ambiguous. The balloon itself will go from a stretched/inflated to a relaxed/deflated state (and thereby pushing out whatever is inside), no matter how the air molecules are initially distributed within the whole system.

The balloon will ALSO relax due to entropy. If you stretch a rubber band, it will warm up. This is due to the relationship of temperature and entropy, where the temperature must go up if we go to a lower entropic state.

Dear Octave, Alessandro + your esteemed audience, First of all, many sincere thanks for your collective efforts! "What is entropy? In what fields is it useful? And how does it explain the direction in which transformations occur? All these answers in 12 minutes!" ...sounds terrific, but this is definitely not for an average mind... ...Even big scientific research workers' brains had and still have to stumble herewith... Hence, some kind of a clarification ought to be urgently necessary! So, captain, AHOY! A. There is ONLY ONE BASIC, fundamental Energy Conservation and Transformation Law. It is definitely unique and conceptually indivisible delivering two logically joint concepts - these are Energy Conservation - and Energy Transformation. Still, a more-then-100-years-old conceptual failure has brought us to two separate thermodynamic laws - but this has nothing in common with the actual physics. To come back, they have coined two more fake thermodynamic laws, employed the Probability Theory + Mathematical Statistics, and this has helped formulate the Quantum Mechanics, which is thus a basically metaphysical conceptual construction - and, hence, ought to be only restrictedly fruitful. B. By dividing the basically indivisible law, you are touching Combinatorics, you are touching Probability Theory, you are even stepping back to Thermodynamics for a while, but... You are NOT answering the poser: WHAT IS ENTROPY, sorry! 1. In the formula S = kB * ln(Ω) you do imply, Ω means not a "Huge Number of Microstates", not "Probability", which numerically ranges between [0,1], not even "Wavefunction", which ought to be a purely metaphysical notion, as it is... In effect, Ω ought to be a simplistic algebraic function of Lord Kelvin's Absolute Temperature. This result has been published 100 years ago in JACS. 2. WHAT-ENTROPY-IS-poser has been answered not by Clausius, not by Boltzmann, etc., but by Goethe, who has introduced Mephistopheles, the philosophical embodiment of ENTROPY. 3. Newton did basically know WHAT ENTROPY IS - A Counteraction. 4. That Counteractions do not grow to infinity with the growing Actions, but MUST reach their MAXIMUM values, is the result by Nicky Carnot, which has been formalized by Clausius... 5. In effect, J. W. Gibbs Free Energy formula: (ΔG = U + pV - TS, .i.e., ΔG = H - TS, where U is the internal energy (SI unit: joule), p is pressure (SI unit: pascal), V is volume (SI unit: m3 = m*m*m), T is the temperature (SI unit: kelvin), S is the entropy (SI unit: joule per kelvin), H is the enthalpy (SI unit: joule)) renders implicit the interplay among ALL the relevant Actions (the Enthalpic term) and ALL the pertinent Counteractions (the Entropic term). 6. The standard approach you are reporting about is OK for the implicit Enthalpy-Entropy picture, employing it, e.g., for studying reaction mechanism details is likewise eating soup with a fork. The above is about 'Entropy' in Physics, Chemistry, Biology, etc., etc., etc. ... Entropy in other fields: Be aware of a powerful trend to build up misnomers in many other fields, for Entropy is the proper term solely for the "Energy Transformation", whatever nature/origin this energy might be of. The Arrow of Time: This is not due solely to Entropy, but owing to Eternal Entropy-Enthalpy Compensation. This is why, the Heat Death you are proclaiming over and over again ought to be just a useless legacy.🧐

I'm only at 7:43, but I want to pause to say I really appreciate your relation of entropy to physical experience, when you say that "physical systems tend to homogenize", instead of falling back on a circular argument like "time just passes". So many shows tend to link "entropy" and "time" in a philosophical or cultural way, but your script reminds us of the importance that "the physical intuition" or sensation or experience of a balloon, or boiling water or melting ice is at the core of discussions about entropy. You make this perspective so clear! ... And of course you have a great sidenote later to clarify that gravitational entropy and other things are still worth thinking about outside of this intuition

This is the best explanation of entropy I've seen yet, thank you

Man... this is by far the best explanation of entropy. Thanks

I'm not sure that the explanation of the tendency for entropy to increase with time explains the arrow of time. The thought experiment (and discussion that follows) I first heard from Carlo Rovelli: Imagine removing the partition in the middle of a box separating vacuum and a uniform gas; allow the gas to evolve in time and it begins to partially fill out the previously empty space; before equilibrium is reached, say when the gas is "3/4 of the way to uniform" freeze time; if, then, we evolve forward in time, the expansion completes as expected, but, if instead we run time backwards, **the same thing happens**, the gas still evolves to a high entropy state, filling the container uniformly! So why do we associate an arrow of time with an increase with entropy? Because entropy was lower in the past. The gas was pumped into half the container using low entropy electricity generated by low entropy fuels that came from low entropy solar radiation and on and on back to the big bang. Why was entropy lower in the past? That is the mystery. Hopefully someone else remembers this argument better and can provide some links!

​@@biblebot3947 In the thought experiment, he's not saying that entropy "supposedly increased" when the arrow of time was reversed. Rather, he's saying that the *argument* for why entropy increases towards the future should logically equally well apply if you look at the picture "backwards", and entropy therefore *should* also increase towards the past ... and yet it doesn't. The Huw Price article (book, actually) which I linked to elsewhere says that way back when Boltzmann first introduced these various concepts, he (Boltzmann) also realized that his arguments *should* apply equally well when looked at in reverse -- entropy logically *should* increase towards the past, as well as towards the future -- and the real mystery is why it only increases in one direction. (And that the mystery is also why we happen to live in such a relatively low-entropy time.) That book explains Boltzmann's reasoning, Boltzmann's solution to the problem (which Price says was ultimately incorrect, but much closer to correct than anyone's solution until recently). The book does so far more clearly than I can do ... and in far more detail than I'm willing to attempt to give. ;^) So I strongly recommend it.

One of the best, maybe the best science channel, at least for GR. Entropy is a tricky topic and rightfully there is a disclaimer at 8:41: degree of (increasing) structure is many times confused with a degree of lower Entropy and vice versa: higher Entropy less Structure (also not true in general). E.g. two layers of oil and water phase separation (looking more structured) has higher Entropy relativ to an oil-water mix after shaking. I wish that this is the first of an introductory videos to that fundamental subject.

Been waiting for a video like this. Entropy is best understood is a heat tax and the reason why time only travels forward. To reverse time is to reverse physical processes, and a perfectly reversible process with no energy loss is not possible because a perfect insulator would imply it aborbs molecular collisions without absorbing energy.

The entropy of this channel never increases.

It makes you wonder about boiling water at different altitudes; where air at high altitudes has a higher entropy which means reduced air pressure. This allows water to boil at lower temperatures than sea level because there is less dense air molicules holding down and preventing the entropy increasing by gravity. Its also why steam or heat rises rather than falls like dry ice vapour.

I just finished your videos explaining general and special relativity and I have to say I was caught off guard by your natural talent as a teacher. Your videos are very impressive on their own, and you're ability to dive into such nuanced theories for 10-15 min at a time, without going on tangents or losing your focus, is what really makes you such an effective teacher in my mind. I genuinely understood 100% of all the things you said, which is not something I get out of any other videos from educational KZreadrs like Vsauce, PBS Space Tme or Veritasium, even though they're titans with millions of subs and plenty of money and time. Other educational videos almost always start with a single topic, but become unintentionally superfluous as unnecessary tangential information is pilled on. You are laser focused, you'll give several extremely relevant, yet simple experiments that offer unique visual representations in order to shed more light on a single topic. You did this while covering general relativity when you visualized space-time in 3d while also using a warping grid to represent the passage of time as an apple falls towards earth. Considering your other videos and explanations, it's easy to see how creative, concise and coherent you are as a creator/educator overall. Serious props man, you're fantastic

The macroscopic description of entropy is thermodynamics while the microscopic description is statistical mechanics. And so homogeneous structures (macrostates) are far more likely to come up in a random set because they have incomparably more microstates than ordered low entropy structures

This is an amazing explanation

That time may not actually exist but be an emerging property of entropy makes a lot of sense.

Entropy comes from the Greek "εν" (en) meaning "inner" and "τροπή" (tropy) that means change. So entropy it translates to inner change.

Long live for scienceclic and dialect

This is epic! You should try doing a video on the quantum hall effect :)

One technical issue at 1:22: the entropy is not assigned to a particular microstate but to a macrostate, being a collection of microstates. The more microstates belong to a macrostate, the higher the entropy of a macrostate. Hence, the image has no entropy; the correct way to express it is that it belongs to a higher-entropy macrostate. Similarly, see 5:00, Shannon’s entropy is a measure of an information source, not a particular message. Another issue: in the presence of gravitational field, the increase of entropy is not in line with increased homogeneity, it is the opposite. As time passes, gravity makes a homogenous gas more and more inhomogeneous. Anyway, the channel and the movie are fantastic.

I like to think of entropy in terms of gradients and change. Gradients are self-neutralizing. There's a gradient => change occurs => the gradient ceases to exist => no more change is possible. All in all, there's only a finite amount of change that can occur in the universe. We just happen to be living in a time where that amount hasn't run out.
