You can run this kind of simulation on any PC because they are not run in real time. It can take few seconds per frame to render. But once every frames are generated, you just pile them at 30fps
@@john_hatten2862 if you wanted you could literally run this simulation by doing the math yourself for each frame. It’d take fucking forever, but you could.
@@connorcriss oh man I can't imagine how precise you must be to make it work. If you round at 0.000000000000001 (assuming the pendulum lenght is 1), you would still get completely different results after few seconds
It's like... the closer together they are in angle, the longer they stay seemingly in sync, and yet the more vehemently they separate once they fall out of it
@@joshuahudson2170 The simulation is correct for a double pendulum system made of two point masses (the rod connections are massless, thus being impossible to replicate in the real world). These systems are easier to solve then a real double pendulum that has mass associated with the rod connection, not just the pivot and end point. Regardless, double pendulum systems are great examples of chaotic motion and it is hard to guess how they will behave without solving the system as is shown. The most interesting part of these systems is that one may find some initial conditions that, even after a very long time t, the masses of the pendulum have not entered one or more bounded regions. These regions are usually vertically symmetric. You could have some double pendulums swing for all time, assuming no external resistance or damping, and still have neither mass ever enter a particular region, while knowing this region is defined by your initial conditions somehow. We just don't have a functional form defining that area from starting conditions due to the nature of chaotic motion. Since we know classical mechanics, which describes this interaction, is deterministic, a functional form should exist but we have yet to derive it and are stuck having to solve, across t, a two point mass system.
Have you ever truly experienced the k-hole where your mind disassociates from your body and reality? Have you ever experienced the feeling of your mind searching for reality while no longer being certain that it exists or what it is?
Me: WHY does RU-vid constantly keep recommending me random double-pendulum videos? I don't really care about this besides as a mathematical curiosity Also Me: *clicks on and watches every recommended double-pendulum video*
@@Bob13454 The spread of those pendulums would only happen for different lengths. If they are all identical, they will all follow the exact same path and no pattern will be produced
I love how you can (basically) point at the moment that the system transitions to chaos. This is particularly true of the later examples where initial conditions are quite close. I wonder if generalizations can be made about the ways in which this phase transition occurs. Another very interesting video is "Space-Time Dynamics in Video Feedback" from 1984. Equal parts art and science.
I like to imagine the edge of the pendulum to be the point where things become statistically impossible. What i like about this allegory is that in real life, one of the million pendulums will eventually break and fly of this metaphorical circle of probability and make the impossible happen.
I feel like these presentations is one big metaphor for life. You start out simple, orderly, and ready for your next thing to do, then when you're an adult, your life devolves into utter chaos where there is no order and you don't know what to do.
i want to see better screensavers like the start of each segment of the showcasing of the pendulums swinging, but the smoothness and spectrum kinda thing just keeps going
It seems like “unfolding” events are when the most chaos is introduced There are kind of two types, which I will call Rotary unfolding and Linear unfolding Rotary unfolding is when the upper pendulum swings not quite a full way to pointing up, but stops short and the secondary pendulum swings a full circle The second type of unfolding, linear unfolding, is when the two pendulums face opposite directions, so the tip of the second pendulum passes through the beginning of the first, and it takes varying time for it to leave that position, and different directions and speeds it can leave at, causing it to split into a variety of discreet groups which can later break apart
