What Is Entropy? The Arrow Of Time Explained!
HTML-код
- Опубликовано: 21 июл 2024
- ⭐️ When we look around us, there is no ambiguity about the direction of time: it only moves forward. If we would live in a microscopic world instead, the distinction between part and future would not be so clear. How do the laws of motion, that do not have a time direction, lead to a macroscopic world where time does have a preferred direction. In this video, we'll find out.

Nice Video...! Time following the same path backward is even rarer...!
Thank you, it means a lot to me (:
Yes, that would be unimaginably unlikely :D
I love this video! The visuals make it so much easier and more pleasant to follow 🙌
Thank you!! (:
I liked this video very much. I appreciate that you first built the base then explained what entropy really is. Others just go straight to entropy and mix up everything!
As always, thank you! It was indeed the idea to approach the second law of Thermodynamics from a way that is intuitive, rather than "out of the blue". :)
Good video but I disagree with your notion that entropy is the cause of our perceived arrow of time I feel the fact both the arrow of time and entropy go foward is just a coincidence not evidence they are relayed
@@schakiarligonde1736 You could say that they are both synonymous with each other. BUT, what would be the underlying reason then, pushing them both forward independently? Any suggestions? :)

new spacetime being created everywhere seems like a replacement rather than a mixing
That seems right. I did not really refer to spacetime mixing in this video, but rather the atoms inside spacetime. If you want to learn more about spacetime, check out my other video, and future videos of course ;)
:D
YES TO "ATOMS"! Boltzmann would have undoubtedly found this video intriguing 🤓! Your ability to elucidate and entertain by connecting our everyday observations to scientific principles is much appreciated. I thoroughly enjoyed the video and believe that this approach to teaching should be implemented in schools!
I also liked the Spherical Cow Approximation 😅🐮🐄
@@dreamworlddweller Haha same :)
Boltzmann would have been amused with the visualisations, I wonder if he pictured the microscopic in this way. Thanks for the comment :)
@@dreamworlddweller Thank you for the cow design :))
Congrats!!
✌🏼
My Mind was blown!!! 🔥🔥🔥🔥
Awesome! Nature is a beauty 😎
I have never heard this topic be explained like this and I can’t thank you enough for making this video! I am bummed out however that you only have one other video! Can’t wait for more!
This makes my day :) I am happy to help. More content on the way! :D
Each interaction is a singularity. No two interactions are identical. Perpetual motion doesn't repeat its path. Similarities are probabilities. Lightning can strike the same object, but on a different path and point of origin. Time is a probability of measuring with past events that may take place in a familiar pattern of past observations of uninterrupted velocity, motion, and distance taken in accordance with probability. We observe past events always. We can guesstimate this action as a repeat probability. Points of origin are always changing. Change is inevitable. Similarities are not proof of exactly the same. Origin is the cosmic speed limit of interactions. It is always changing places and points.
Another excellent video. I selfishly hope you find time and motivation to make more videos like this one.
Thank you, your message means a lot to me :)
I am desperately looking for more time :)
The animation and explanation both are excellent. It would be very helpful if you shared the manim code..
I will at some point, I'll have to tidy it up :D
Again wonderful video on physics...thanks... please more videos!!
Perhaps soon ;)
We are waiting 😊
Time I.S. Thought ~~ Timing I.S.Thinking = Creation In Action
So if I'm not thinking, what happens?
I still have trouble with this concept. Entropy increases in an isolated system. Isolated systems are rare in the cosmos. It is easy to create a system for which the entropy decreases, at least for a while, e.g. in a refrigerator. However, time does not run backwards.
Well, that depends on the frame of reference, and what you compare with. Let's say you refrigerate a volume of air. Temperature is the average kinetic energy of the atoms. Since the temperature drops, the average kinetic energy of the constituent atoms drops, which makes it so their distribution of velocities is less spread out. Or in other words, the possible states these atoms can be in (their momentum) decreases. Now, if you would not be aware of the external power powering the refrigeration, you'd be thinking time is indeed going back: atoms going from disorder to order.
PS: Great question!
So we are in the MATRIX, got it!
Can you specify what you mean with the Matrix? And how it relates to what I cover in the video? :D
@The Why of Psi Simulation Theory is in the zeitgeist of pop science atm. People's closest understanding of it is The Matrix. Is an annoying meme
Thank you, very nice explanation of the statistical nature of the evolution of many bodied systems, which we often interpret as time. Thought I'd point you at Kathy Loves Physics and History for an in depth history of Boltzmann's equation, including how it, and the constant, wasn't actually written down like that until Plank took it a stage further! ruclips.net/video/Tr_gv5CKB1Y/видео.html - leading to the quantum revolution.
Cool, thanks for the kind words! And I will definitely check that out, sounds super interesting :D
Are you available to have a business chat to explore avenues for promoting your course, increasing enrollment, and generating positive reviews.
What course do you mean? :)
I am always open for business inquiries ;)
One thing - the pendulum example that you gave isn't technically a "microscopic" system, right? It's a "simple" system (I don't know what the technically correct term for that is or how to quantify it).
Even two giant solid spheres in empty space moving directly towards each other, colliding, and then moving apart - that would also be a simple system (even though not microscopic) - in which we can't tell if it's moving forwards or backwards in time.
So maybe in the realm of classical physics, micro and macro states aren't the most precise terminology, and instead simple and complex are more appropriate? (obviously going into the quantum physics domain opens a while new can of worms)
You are completely right in your remark. I should have called it an "idealised system", instead of microscopic. I intended to allude to a pendulum without any friction or any internal dynamics.
Most of the time, microscopic states correspond to the systems that can be described by very few parameters, and are idealised.
Quantum Pendulum (Harmonic oscillator) is something I have planned to deep dive on in a future video! :D
Thank you for commenting btw :)

Hi. You will not believe this. Lol. What happened was just so weird. Wow. You know how you're always going back to checkpoints? This whole life is a checkpoint. I wondered a couple of nights ago that there was no such thing as wise, as in the eternal wize.. If there was, then we would not feel beauty, truth & love anymore. These things will hurt us all your life, for what to hurt us. ..If you are wise, Why would you be at a checkpoint? You couldn't be able to be at a checkpoint if truth, beauty & love you could not feel anymore.
When you're too wise, you can't detect checkpoints.
📖✍️We Did it!!! Come see!! *Drops to knees & cries*.
Here we went back to the source of life, but we went further back, to The Source Of Variations Of Source Of Life. & he said "You're not wise. I am wize." & he lifted me up in his hand & blew me back to the source of life. & we were the source of life at the source of life. I opened my eyes, & I was back, sitting at my table, comparisons as much as the comparisons I draw, a tool, like my pen. God is the word. ..
..on faceeee. On the ark.
I host an abiogenesis experience.
Then I find out my mother's blacked out. She's ok. ..Wow.
.. Faceee. On the ark. I host an abiogenesis experience. ..Come along *brrrr*
Why did you stop making videos?
I have many other things that require my focus. I made an ai-powered math and science tutor (ai-tutor.io), I'm in the process of finishing a lengthy Statistics for Data Science course. And, I have a full-time job :)
But, I would love to just focus all my attention back to these kinds of videos, as they give me the most fulfilment. Thank you for your message! :)
Quite dedication! Best of luck with everything! Glad I just came cross your channel, I admire the ablility to consisely produce such high contents, thanks a lot!
Comments like this give me extra motovation to make the next video! Thanks!! 🙃

done@@whyofpsi
times doesnt move forwards, our consioucsness does, by dimension jumping to another dimenion that has moved slightly. because all dimensions are fixed and cant be changed, therefore to move an object you need to leave one dimenion and go to another where the object is already in the new position. That is how the illusion of movement and time works.
Does that mean you'd hypothesize an incredible amount of dimensions? How would you test your explanation against the ones established by physics now?
@@whyofpsi well its not my hypothesis, its known within metaphysics sources, which means it's not yet science. To say there was an incredible amount would be correct. Anything you could imagine, which means the scope is not just what our reality could be (earth \ physics etc), but what we could imagine. So a version of you right now wearing a pink hat also exists because its within the scope of a persons imagination. You can't imagine anything that doesn't already exist, that is what our imagination is. From our perspective we would consider it an infinite amount, but apparently it is actually a finite number, just insanely large. I would say there are tests that could be done, to prove the concept, but they haven't yet been discovered.
@@whyofpsi You loving this comment, does that mean that you are backing this theory?
@@ruthhuijgens No, that does not mean that. In this case I do in fact not agree with the hypothesis. I hearth the comments because I love when people take the time of day to elaborate on their thoughts.
Because motion is forward momentum in resistance to repulsion and propulsion.
What do you exactly mean? :)
Thanks for commenting :D
@@whyofpsi magnetic fields are force of unification of unidirectional flow cycling thermaldynamics in resistance to repulsion to forward momentum propulsion of resistance. Propulsion in resistance is constant forward momentum. Cosmic speed limit of heat as perpetual forward momentum. In unification of unidirectional flow of thermaldynamics entanglement, it's in repulsion. Mass is equalization of resistance within and without it. Mass occupies space as space. Density occupies space as outward force of pressure known as weight in mass. Mass in resistance to the nucleus of cold space. Hydrogen under extreme pressure expands cold resistance into helium. Unification of unidirectional flow cycling thermaldynamics in magnetic fields. Distance is reduced by redirected trajectories of thermaldynamics into cycling circulation patterns of magnetic fields holding mass together in resistance. Magnets show the bonding pressure of forced pressure cycling circulation patterns. Outward pressure of force is repulsion to thermaldynamics in mass. Table of elements proves hypothesis. Mass occupies space as space. Cold resistance expands in mass in equalization to pressure of forced repulsion of thermaldynamics. Black holes are devoid bubbles of thermaldynamics. Expansion of space itself. Thermaldynamics is pressure.
@@timothy8426 I am not able to understand a single thing.
@@icebeartwo Mass is in equalization to resistance. Thermaldynamics is heat. Heat is various degrees of pressure. Force of pressure known as weight. Quatum magnetic fields of forced pressure cycling circulation patterns as mass. Mass is thermaldynamics in different degrees of resistance. Mass occupies space and space in mass is equal to resistance of pressure as outward force of pressure known as weight. Heavier mass falls at the same rate as lighter mass because resistance is always equalization to mass. The distance is reduced by redirected trajectories of thermaldynamics in mass as repulsion to thermaldynamics. Pressure is equal in all masses. The energy in the heavier mass has more redirected trajectories than light mass. That's why mass falls in equalization. Heat is thermaldynamics, and cold resistance coexist as space itself. Perpetual motion. Resistance repels thermaldynamics toward the weakest point of resistance. Thermal energy singularities spiraling and spin in forward maximum momentum velocity in resistance. Conservation of maximum momentum velocity in resistance is heat singularities frequency outside of unification of entanglement. Distance is at its greatest speed limit in resistance as singularities. Hydrogen under extreme pressure from thermaldynamics squeezing in on it causes resistance to expand in equalization to pressure. It expands cold resistance into helium. More occupational space and thermaldynamics. Cold resistance expands in mass in equalization to pressure of forced pressure cycling circulation patterns of magnetic fields as weight contained within quatum forced fields of pressure. Inward and outward pressure. Outward pressure is weight. Inward pressure is expansion if equalization to pressure is needed. Repulsion to forward momentum propulsion. Resistance is both repulsion and propulsion. Elements are formed by this process. Atoms have cold resistance at their core. Cold space itself. Thermaldynamics curves around these bubbles of pure fabric of space itself devoid of thermaldynamics. Thermaldynamics unification is redirected by magnetic fields. Magnets show the bonding power of atomic pressure. Mildly. Mass is equal to resistance within and repulsion without. Spheres are proof of pressure in resistance to equalization of pressure. Mass is the weakest point of resistance. Occupational space of mass neutralizes resistance within as outward pressure of force known as weight. Mass is repelled towards the weakest point of resistance. Earth. No gravity. Mass is outward pressure. Density occupies space. Space is cold resistance. Density can't exceed resistance within it. Proximity mass is repelled towards the weakest point of resistance. Unification of unidirectional flow. Forced fields of pressure. Thermaldynamics is pressure in various degrees of releasing or accumulation. Absorption is expansion. Heat loss is decay. Ice pressured by thermaldynamics expands into water. Squeezing water into steam. Squeezing steam into gas.
@@timothy8426 I, also, do not understand what point you are making.
Think too
much 😅
A cat doesn't think that and
live happily 😜
That is very true. I think the beauty is in the undulation between deep thought and zen like empty-mindedness of a cat (:
