Woah amazing. That's the typical misunderstanding, or rather misuse of fractals shown right here. A fractal typically isn't self familiar. The reason we focus on those is because they're beautiful and easily produced but a fractal usually is way more chaotic, like the one shown here. It's awesome man, great vid
2:05 there's obviously something wrong with this simulation. Look at the pendulums at the bottom right corner. It's spinning around faster and faster, which means the mechanical energy involved is increasing over time. Now, if I were to guess it's rounding errors which is unavoidable, but there are some simple error smoothing you can add: for every frame, after you calculate the angular velocity/angles of the next frame, first calculate the total energy invovled with that, and then normalize it back to the value you started with, then have the normalized result be fed into the next frame. You'll still get slightly off results, but it won't be quite this drastic.
I think you made a mistake in concluding that mechanical energy involved is increasing over time, because here we have two pendulums which are exchanging energy with each other while keeping the total energy constant. What we see as spinning faster is one of the pendulums while the other pendulum swings slowly to conserve energy.
It depends on the numerical integration scheme being used. Because the simulated double pendulum model has no damping, certain numerical integration schemes will indeed cause what looks like an increase in mechanical energy over time. I was just earlier today watching a great video by Steve Brunton called "Stability of Forward Euler and Backward Euler Integration Schemes for Differential Equations" that explores this for a basic numerical integration scheme and a linear ODE.
Beautiful representation :) I have always wondered whether the double pendulum would retain any sort of continuity after having heard of chaos theory. But hey, it did (somehow)! and that is a nice looking turbulence.

@@nicogsplayground I find the probability heat map overtime especially inspiring. Its almost like blending together spatial-temporal dimensions into a new realm of its own.
A similar 2D fractal is created when you plot starting angle of the hands of the pendulum. I wonder how a 4D fractal would look like that combines the dimensions of hands lengths and their starting angles.
Converted the angles, which we mapped on the grid to colors, rgb values. (01:57) But you are right that I should've probably put more emphasise on that!
@@nicogsplayground Makes sense. Since this looks like a continuous map and angles need to jump back to 0 if they go past 2π, you would need to map the sine or dot product or something like that to RGB space. Do you know the exact details?
@@Evan---- Thanks!!! They often take a lot of time. Keyframing and tweaking curves so the speed and motion fits the whole composition and story line, can take hours for maybe 0.8 seconds of motion. Knowing that it doesn't go unnoticed by others really makes my day, appreciate it!
Motions in chaotic behavor is based on nonlinearity of the mechnical systems. However, chaos is not a random motion. As you have seen, the motion can be described with a specific nested structure, which is called fractal.
@@nicogsplayground Thanks for your answer. Nothing is random, therefore chaos doesn't exist. In fact, I can't even grasp what chaos would be, or how even hypothetically could exist...
@@ConnoisseurOfExistence that’s why it’s called Chaos Theory. The idea isn’t that something behaves randomly, one can predict it’s behaviour given the initial conditions. But when we try to determine the initial conditions based on it’s behaviour, it get’s pretty hard because of the “chaos”.
@@nicogsplayground Maybe we can't even determine its exact behavior (future state, position and momentum) from the initial conditions, without actually letting it play out.

This is not a fractal. Fractals exhibit self-similarity across scales and typically have a fractal dimension, representing infinite detail at any level of magnification. While fractals exhibit deterministic patterns even within their complexity, the compound double pendulum's chaotic nature lacks a recursive or self-similar structure that would persist infinitely as with fractals. Also we are faced with undecidability. In theory I could arrange a configuration that "stops" at a certain depth without for you to know in advance by trivial means.
Would this be considered a fractal? I thought fractals require self-similarity... Wouldn't this be a subset of samples of the phase space of the system evolving as you scroll forward through time? Sorry if this is a dumb question.

They are saying that "Chaos theory suggests that minuscule changes in initial conditions can lead to massive differences later on" But that is WRONG. The particular part that is wrong is the "minuscule changes". The changes are not "minuscule", they are *INFINITESIMAL* and that is where chaos arises. We have a function, a real - DETERMINISTIC - function, that perfectly describes from the initial conditions that we gave to the computer of the experiment... But in order for that function to be calculated we need INFINITE amount of time... Because the function's graph is a fractal... And thus, *INFINITESIMAL* changes can create non-infinitesimal differences later on. Thus, we can never fully create a perfect model for our experiment, because the information that we need to know is infinite.
@@-_Nuke_- Small differences in initial conditions, such as those due to errors in measurements or due to rounding errors in numerical computation, can yield widely diverging outcomes for such dynamical systems, rendering long-term prediction of their behavior impossible in general. This can happen even though these systems are deterministic, meaning that their future behavior follows a unique evolution and is fully determined by their initial conditions, with no random elements involved. In other words, the deterministic nature of these systems does not make them predictable. This behavior is known as deterministic chaos, or simply chaos. Sources: Kellert, Stephen H. (1993).

@@nicogsplayground I agree! My nitpicking part is that these differences in initial conditions don't need to be small, because the word "small" is still a huge word in the world of chaos. Even an infinitesimally small difference will be enough for the whole thing to derail into chaos. I just made this comment to really emphasize the sheer infinity in the nature of chaos.
As much as i love the visuals, sound, and explanation (it was very well made), please credit Sam Maksimovich for his first original take on this concept (th-cam.com/video/n7JK4Ht8k8M/w-d-xo.html). It is so clearly tied to his video on it, even using the same concept and even color mapping.
@@ray-pu8vt To be completely honest, I came by a paper with the same name written by Jeremy S. Heyl more than 16 years ago. The next and basically only source I worked with was a blog post by Jason on the softologyblog While working on the visualisation someone on reddit replied with a code snippet, with a very neat implementation for the colors coming from Nikolai Mikuszeit, published in 2015, which on its turn was based on the colors from a book: Symmetry in Chaos: A search for Pattern in Mathematics, Art, and Nature, by Micheal Field and Martin Golubitsky. As I used different measurements I tweaked it so the colors would match. It is only after coding the project, putting it together in a video & finishing it all together that I discovered the TH-cam video by Sam which is awesome! Although I do not mind giving credit where credit is due, but I don’t see how this should be the case here. I explained a mathematical phenomena, from a different perspective, and from a different input angle with Chaos Theory. Nor was Sam the first discovering the concept, nor the usage of the colors. But regardless, being the first to discover of a mathematical concept, is different from being the first to create something, in which credit would certainly be appropriate. In this case I don’t see how it would be appropriate nor fair to credit Sam. (And this is nothing against Sam or anyone else, love his video, and I will add this to the description + all the resources I did use to come to my visualisation, not because I think credit is due, but rather so that others can see another way of explaining the concept)
@@nicogsplayground Im terribly sorry for taking such a one sided perspective on your video. I now realize that i was wrong and that you had no real intention to directly copy Sam's video. Thanks for clarifying!
@@ray-pu8vt That is 100% okey! In a world of social media we can let the one sided POV’s get the best of us, although we are aware another side of a story could exist. I respect your time & energy you put in defending someone’s work btw + The fact that you are aware of the other side now & decided to apologise is a something so rare in a comment section of a TH-cam video, that I’m honestly so grateful for the reasonable & very mature comment. I appreciate you
Motions in chaotic behavor is based on nonlinearity of the mechnical systems. However, chaos is not a random motion. As you have seen, the motion can be described with a specific nested structure, which is called fractal. around 02:52, the edges, every pixel represents a pendulum that had less than 0.001 deg in difference, but the vast amount of different colors shows the chaos that emerges from smaal initial differences. Many other chaotic systems look symmetrical btw 🙆♂
Appreciate it! When simulating a double pendulum the mass of the two balls and the length of the legs connecting them stay constant and won’t change over time, that’s what I meant with “constant variables”. Meanwhile the position of the balls or the angles made by the legs are variables that change. I Should’ve said that indeed, thanks for the feedback!! 🙏🙏
Chaotic pattern does not equal fractal. And I really wish young people would stop misappropriating words like that. Of course, considering the way they do it so recklessly in so many other areas of their lives, I wont be holding my breath. It funny how entire generations celebrate science and understanding and acceptance, to just throw it all out the window and fight so voraciously for their misguided ideals. No, instead Ill be quietly weeping to myself, "they try to sound smart but they're just so arrogantly stupid..."
I was tempted to simply write “Oke boomer” Someone who would write off a whole generation because of their incorrect & preconceived notions on this subject, could indeed be described as trying to sound smart but just being arrogantly stupid. Numerical simulations of the double pendulum reveal that the set of initial conditions within a set period of time has a fractal structure. Specfically, the boundary of this set is a fat fractal similar to that found by Farmer for a simple Hamiltonian logistic map, indicating that fat fractal boundaries may be a hallmark of chaos in non-linear Hamiltonian systems. Sources/further reading: J. D. Farmer, Physical Review Letters 55, 351 (1985). Or a great introduction to what I used as inspiration for this video, the “Double Pendulum Fractal” paper by Jeremy S. Heyl (Department of Physics and Astronomy, University of British Columbia, 2008)

This can happen even though these systems are deterministic, meaning that their future behavior follows a unique evolution and is fully determined by their initial conditions, with no random elements involved. In other words, the deterministic nature of these systems does not make them predictable. This behavior is known as deterministic chaos, or simply chaos.

@@nicogsplayground I agree! My nitpicking part is that these differences in initial conditions don't need to be small, because the word "small" is still a huge word in the world of chaos. Even an infinitesimally small difference will be enough for the whole thing to derail into chaos.
I just made this comment to really emphasize the sheer infinity in the nature of chaos.
Blud thinks he is an artist (is one f*cking genius ) ❤
how do you even convert angels into points?
😕😕😕😕😕😕😕😕😕😕😕😕
(x,y) = (theta1, theta2) = (first angle, second angle)
Absurd, what have you used to create this?
Thank you so much 🙏🏻 Using Javascript & the p5js library for all the simulations 🙆♂️🙆♂️
it looks like starglow from after effects
The plugin? Never used it tbh, what part of it’s functionality has a similar look? 👀 Could be interesting for future video’s 🙆♂️🙆♂️
@@nicogsplayground the warping and the colors!
bro that graphics card probably got cooked 😭😭😭

Is this actually a fractal? From my naive understanding, it doesn't seem to be a fractal
Can you do it with n-pendulum?
@@adrienledoux357 In theory yes, but then we should have an n-axis grid, which wouldn’t create anything interesting I guess haha
Even 3D glasses wouldn't be enough for that. You'd need nD glasses, not to mention a biology that could make sense of it.
lol i thought you were a tts
As much as i love the visuals, sound, and explanation (it was very well made), please credit Sam Maksimovich for his first original take on this concept (th-cam.com/video/n7JK4Ht8k8M/w-d-xo.html). It is so clearly tied to his video on it, even using the same concept and even color mapping.
@@ray-pu8vt To be completely honest, I came by a paper with the same name written by Jeremy S. Heyl more than 16 years ago.
The next and basically only source I worked with was a blog post by Jason on the softologyblog
While working on the visualisation someone on reddit replied with a code snippet, with a very neat implementation for the colors coming from Nikolai Mikuszeit, published in 2015, which on its turn was based on the colors from a book: Symmetry in Chaos: A search for Pattern in Mathematics, Art, and Nature, by Micheal Field and Martin Golubitsky. As I used different measurements I tweaked it so the colors would match.
It is only after coding the project, putting it together in a video & finishing it all together that I discovered the TH-cam video by Sam which is awesome!
Although I do not mind giving credit where credit is due, but I don’t see how this should be the case here. I explained a mathematical phenomena, from a different perspective, and from a different input angle with Chaos Theory.
Nor was Sam the first discovering the concept, nor the usage of the colors. But regardless, being the first to discover of a mathematical concept, is different from being the first to create something, in which credit would certainly be appropriate.
In this case I don’t see how it would be appropriate nor fair to credit Sam.
(And this is nothing against Sam or anyone else, love his video, and I will add this to the description + all the resources I did use to come to my visualisation, not because I think credit is due, but rather so that others can see another way of explaining the concept)
@@nicogsplayground Im terribly sorry for taking such a one sided perspective on your video. I now realize that i was wrong and that you had no real intention to directly copy Sam's video. Thanks for clarifying!
@@ray-pu8vt That is 100% okey! In a world of social media we can let the one sided POV’s get the best of us, although we are aware another side of a story could exist. I respect your time & energy you put in defending someone’s work btw + The fact that you are aware of the other side now & decided to apologise is a something so rare in a comment section of a TH-cam video, that I’m honestly so grateful for the reasonable & very mature comment. I appreciate you
I see symmetrical pattern, not chaos
Motions in chaotic behavor is based on nonlinearity of the mechnical systems. However, chaos is not a random motion. As you have seen, the motion can be described with a specific nested structure, which is called fractal.
around 02:52, the edges, every pixel represents a pendulum that had less than 0.001 deg in difference, but the vast amount of different colors shows the chaos that emerges from smaal initial differences. Many other chaotic systems look symmetrical btw 🙆♂
I’d love to see this fractal projected onto a torus
Nice video but chatgpt ahh script
God(s) resides in chaos
"length and mass are constant variables" doesn't make much sense but the video was good
Appreciate it! When simulating a double pendulum the mass of the two balls and the length of the legs connecting them stay constant and won’t change over time, that’s what I meant with “constant variables”. Meanwhile the position of the balls or the angles made by the legs are variables that change. I Should’ve said that indeed, thanks for the feedback!! 🙏🙏
Chaotic pattern does not equal fractal. And I really wish young people would stop misappropriating words like that. Of course, considering the way they do it so recklessly in so many other areas of their lives, I wont be holding my breath. It funny how entire generations celebrate science and understanding and acceptance, to just throw it all out the window and fight so voraciously for their misguided ideals. No, instead Ill be quietly weeping to myself, "they try to sound smart but they're just so arrogantly stupid..."
I was tempted to simply write “Oke boomer”
Someone who would write off a whole generation because of their incorrect & preconceived notions on this subject, could indeed be described as trying to sound smart but just being arrogantly stupid.
Numerical simulations of the double pendulum reveal that the set of initial conditions within a set period of time has a fractal structure. Specfically, the boundary of this set is a fat fractal similar to that found by Farmer for a simple Hamiltonian logistic map, indicating that fat fractal boundaries may be a hallmark of chaos in non-linear Hamiltonian systems.

I wonder how much AI you used in the video making process. The wording of some sentences sounds kind of... non human.
English is not my first, nor my second language. With dutch & frensh being my motherlanguages, some of the sentence structures might sound strange, except from some suggestions by NotionAI for better words & grammar, the script is written by le me. 🙆♂️ first time someone called my writing non-human, but I’ll take the compliment as “out of this world” 😅❤️
Unless you where talking about the voice over, that’s actually a mistake 💀 As I hate recording my voice (accent, english yk) I always edit my video’s with an AI generated voice, so that by the time everything is edited I know every word of the voice over & at what pace I should say them. I only have to replace it with my voice recording, at the very last. Unfortunately I uploaded the wrong version & only realised the mistake a few hours after publishing 😅😅
Don't like the AI voice, feels soulless and uninteresting to listen for more than a few seconds.
I agree! As mentioned before: I hate recording my voice (english second language yk) I always edit my video’s with an AI generated voice, so that by the time everything is edited I know every word of the voice over & at what pace I should say them. I only have to replace it with my voice recording, at the very last. Unfortunately I uploaded the wrong version & only realised the mistake a few hours after publishing 😅😅
