nice! my favourite fact is that it's actually chi distribution with three degrees of freedom. that is, if you take vx, vy and vz from a Gaussian distribution, the magnitude of the total velocity is root of sum of squares of these.
These are the gold standard in the "fundamental physics concepts explained" genre of videos. Thank you. You've been responsible for helping me cement my understanding of so many different areas of physics
Dude. You’re just my hero. As a human who is only capable of conceiving in 3 dimensions, you’re the only guy out there actually - consistently and with intention - creating these 3d animations which *ground* fundamental physics concepts in a way that isn’t immediately obvious from studying pure equations. You understand what the equations actually mean and you show us what they mean. You show us what the original architect was thinking, in a way the original architect could never have done themselves due the technological limitations of their era.
This is the only channel which I have ever been a patreon supporter. Thank you Eugene for always making me proud to be one. My only wish is that there were ten of you producing videos instead of just one.
Continuously I eagerly wait for such videos. The knowledge which I gain from here is much precious to me and always helps me to understand the concept in a more convenient way. Only due to you I clearly visualise what I have ever studied in text books. Really much helpful videos to understand higher academics. Thanks a lot...
Thank you very much, Eugene! Entropy is a concept that I believed I could never comprehend and truly grasp for many years. Without the assistance of your incredible videos, I would probably have never understood it.
Dude. a) your content is top tier. b) thank you for your time in providing this information visually. c) binging your channel immediately, so “not, not a thank you for the first thank you” 😉
When the quantum section started I was like, I already don't know how you count micro states in classical systems! So like is each possible set of positions and velocities for all the particles its own micro state? There's a big infinitely many, do you have to integrate over all of them somehow?
The idea of radioactive decay at absolute zero came to my mind today. My first idea "wouldn't it stop?" was the sign of a misunderstanding of the concepts. - as a video idea
I think the decay wouldn't stop .... The reason which is coming to my mind is that ... Half life of elements is independent of temperature.... Isn't it?
Hello Eugene, as always I am greatly appreciative of these videos you provide us for free. If I may make a request, I would love to see a video from you explaining the shapes and interactions of electron subshells that occur in chemical bonding. I know this is more applicable to the field of chemistry, but this is one particular topic of the physical sciences that I have always struggled to visualize. Visualization seems to be your specialty, and I believe you could help it finally "click" for me, as you have with various other topics in the past; assuming you're knowledgeable enough about said topic to expound on it in the first place. Thank you, I'm a big fan, keep up the good work!
At 4:07, you say that a system is in thermodynamic equilibrium when it’s entropy has reached its maximum value, given the constraints. I might remember it wrong, but I think the statement is only valid if you say that the system is isolated, that is it cannot exchange matter or energy with the environment. In general, again if I remember correctly (15 years ago, in some course of chemistry) , it is the entropy of the system plus that of the environment that has to increase…or equivalently one can talk of the free energy ( of Gibbs, or others, depending on what the system is in contact with ) of a system (for Gibbs free energy, the environment is represented as a sink of heat and pressure, but the system is closed ) reaching a minimum
Did you hear about Lt. Col. Thomas Bearden? ( Rest in peace by the way ) this reminds of a bit of what he was talking about, maybe some videos soon around the idea of scalar electromagnetics?
@@freemanskush7910 It's the linchpin between the macro and micro universe and the basis of pretty much all physics. It dictates the arrow of time; meaning tomorrow happens after today.

Hi Eugene! So, the reason a quantum system has a thermodynamic distribution different from a classical system is also related to the idea of a negative Kelvin scale, correct? This means that when we add energy to the system, causing it to become more ordered, we say it has a negative temperature. However, at this point, it no longer obeys the Maxwell-Boltzmann distribution, right?
الانتروبيا (entropy )، مفهوم في علم الديناميكي الحرارية، مفاده، قياس عدد الأشكال التي يمكن أن يكون عليها نظام ما، و بالتالي يمكن ربطه بالفوضى الذي أيها ذلك النظام. بحيث كلما كانت الإنترنيت كبيرا، كلما كانت درجة الفوضى فيه كبيرة. و الفوضى لها علاقة بتوزيع السرعات التي عليها كل مجموعة من أجزاء في النظام. و المعدل العام هو قياس الانتروبيا
Hi, it was a nice animation, however, I don't see how it's a way "I've never seen", because that's pretty much how it was introduced in our physics class.
First few seconds of the video is played most . I thought I missed something about "few particles are moving" . So I again started from the beginning 😃.
Excellent video as always! I have a question, why are the particles in a quantum system indistinguishable compared to the classic scenario? I could imagine that in a classic scenario if the particles have equal mass and shape. Would the particles also be indistinguishable? Thanks for the great video!
The word "indistinguishable" means more than that. I explain this in my video on the Pauli Exclusion Principle at ruclips.net/video/Zlp2GQ3OLeE/видео.html
Another super beautiful animation video ..... That Maxwell Boltzman distribution curve looked a lot like the blackbody radiation curve... Can you please tell why is there so much resemblance in Maxwell Boltzman velocity distribution at different temperatures and blackbody radiation curve at different temperatures....?
Интересное видео но кажется что мы только в начале понимания сущности термодинамики....хтя бы из того что можно смешивать холодное и теплое но не можем произвести обратное - разделение состояния на холодное/горячее без затраты энергии - тут легко смешать но разделять уже проблема..
How many awards has this channel won over the years? All, I would presume. I tried to follow one of the green particles as it bounced and ricochet throughout the box. Graphic representations have always been mesmerizing as well. Are we changing these results just by observing this video?😁
Thanks for the compliments. Though, I haven't won any awards for this channel. As Mark Twain said, "It is better to deserve honors and not have them than to have them and not deserve them."
Am I not wrong in that someone had to write the code for this program to work, which would mean that this isn't a model of what's actuality happening but rather the person who wrote the codes interpretation of what would or should happen. No computer can produce anything on its own without human input
The code just has the laws of physics as inputs. When we write the code and set the initial conditions, we may have no idea what the outcome will be until the simulation is actually run.
This is the perfect example of the difference between theoretical models and the true reality of the Universe. This model presented here is for kids with a not enough developed mind. If you don't understand what I say here ( or if you wrongly understand it ), then make the model to work for the whole real Universe comprising at the same time ( =simultaneously ) the universal real neverending micro and macro dynamics. Let's suppose that you coudn't do it. But even if you only try, you'll start the process of slowly-slowly understanding how in reality the Universe works.
Cool, but last part I couldn't understand well. That bozon qnd quantum parts. Elektron energy levels etc. maybe my English wasn't so good to understand :(
1:48 Wait, if every (indistinguishable) particle had the same energy, wouldn't that be maximum entropy? The greatest number of microstates == the greatest multiplicity == the greatest entropy. This occurs when every particle is no different than any other particle, no? Which is where the universe as a whole is going. If I had two EInstein solids, with Na and Nb oscillators in each solid, then distributing the total energy units "q" among all the oscillators in proportion to the total number of overall oscillators gives us the greatest multiplicity, no? Omega_total = Omega_A * Omega_B. What am I not seeing? Lowest entropy == lowest possible # of microstates == having one single oscillator with all the energy. 2:38 Not the correct definition of temperature. T^-1 = partial Entropy/partial Energy. 5:43 We don't apply classical thermodynamics to the quantum realm because of the energies compared to the discrete nature of the energy spectrum, which cannot be ignored.
If you have two particles with the same energy, then when you swap their energies, you get the exact same micro-state that you had before (assuming that the velocity directions don't change).
For a given set of positions and velocity directions, let us suppose that we can adjust the velocity magnitudes by redistributing the energy among the particles. There is only one way that all the energy can be in particle #1, there is only one way all the energy can be in particle #2, etc. There is also only one way that all the energy can be distributed exactly equally amoung all the particles. But, there are many different ways the energy can be distributed such that you get the velocity distribution shown.
And that is the correct definition of temperature. The equation you mentioned is just a relationship between temperature, energy, and, entropy, under a given set of conditions.
@@EugeneKhutoryansky You are mistaken. I refer you to Schroeder's "An Introduction to Thermal Physics." E.g., Figure 3.1 shows that entroipy is maximized when a system (Einstein solids, monatomic gas, two-state paramagnets) is at the point where the energy units are distributed such that, essentially, there is no spontaneous loss or gain of energy from one particle to any other particle in the system. This means that the temperature of the system at equilibrium is such that partial S_a/partial U_a == partial S_b/partial U_b == no particle/oscillator spontaneously gives up/absorbs any more energy. Thus, same velocity, thus, temperature does not change. For indistinguishable particles (assumed to sidestep the Gibbs paradox), this means that they each have the same amount of energy, thus, at maximum entropy. FYI, I am pursuing a Master's degree in Physics, and have my Thermal Physics midterm this Wednesday.
This is really great channel what i almost know about science is from this helpfull channel....but i have question about how electron and positron can be form from photon?does this violate pauli exclusion principle? Please can u tell me
I am glad my videos are helpful. Thanks. In reply to your question, the Pauli Exclusion principle only says that "identical" particles can't be in the same quantum state. For example, two electrons can't be in the same quantum state. But, an electron and a positron can be in the same quantum state, because they are not "identical" particles.
Boltzmann Distribution Hey Guys does this model look like it might describe the math in your lecture? Thanks for your well produced video. Your viewers might enjoy seeing my personal amateur science project. Sorry if it’s not a well produced video I need to do better. It might be a good visual aid that the math describes. See linked below. It uses a sheet of spring-like material buckled from the ends to form a Gaussian curve. The area under the curve represents the energy in the system. The sheet of material represents a field with the ends bounded. Seeing the mechanical effect may takes some of the mystery of what the math for your students.
