They are a nice visual representation of some of the MATHEMATICS of the solutions to the partial differential equations of physics. They are also - obviously - visual representations of what sand actually does in response to the surface of the plate. As a physicist I can tell you that the picture here only has a loose correspondence to some of the analogous mathematics that describes the quantum mechanical behavior of a electron subject to certain forces and boundary conditions. What is actually "going on", in as much as that question even means anything in the quantum mechanical context, is not very analogous. One example would be in quantum mechanics the nodes (places where the amplitude of wave function vanishes) are places where the electron ain't, not places where it would be especially likely to be found as with the case of the sand. Still, the different discrete "normal modes" that you see ARE analogous to the discrete states of quantum mechanical systems with certain boundary conditions. One of the most important examples of that are the discrete states (and the corresponding shapes of their normal functions) of electrons in atoms which ultimately is behind all of chemistry - the Ainur singing the world into existence indeed! Interestingly, even partial differential equations for physical systems that never behave in this interesting way - the diffusion of gas in a box is a simple example - also have a countably infinite discrete solutions like the one pictured in the video, but the real behavior is always superposition of many of these, and the behavior of the gas does what you expect it to do which is to spread out until it has the same density everywhere, so a lot more boring. But very similar math.

As well as some CGI, I wonder of Rings of Power is starting with the patterns they want, and then vibrating, then running the footage in reverse.

I guess your voice must sound like that when you sit on a cold Chladni plate.

The way you pinch the plate to force a node is used by guitarists (and probably some other stringed instrumentalists) as well. They will touch the string at a particular point to force a higher note out of the ringing string: often much higher, especially with electric guitars, which can more easily compensate for the lowered volume. (I guess technically they're really removing the lower-order harmonics and making the forced one the dominant frequency of the string.) These are actually often called "pinched harmonics" (although this usually refers to doing it by intentionally touching the string with your picking hand as part of the motion of picking). You can obviously hear this change in pitch as you're bowing your plate.

Then just played the footage in reverse. so it looks, like this floral patterns created naturally. Make it look very mysterious. Good job explaining and a beautiful trailer remake, by the way.

I'll preface this by saying I haven't watched Rings of Power But I do find the idea that they used something like this as their intro actually quite interesting. One of the themes in Tolkien's work is essentially that God / Eru Ilúvatar who along with his Angels / Ainur sang the world into existence By showing something like this in the intro they could very well be showing a practical example of how something like that is possible. Music is just vibrations after all and this is using vibrations to create ordered structure out of chaos. You could even go so far to have it explain how a deity could influence the world sending vibrations that make it easier to settle in places that are in the pattern that it chooses.

That Smeagol impression killed me! You made my day, thank you! :D

What I want to know is, is there a specific geometry of a plate and particle size such that the resonant frequency will match up with the sound of someone screaming, so we can create a chladni figure of someone's scream.

Better than the show! but that doesn't take much thought. Love your content!

so is it possible that vibrations in a 4th dimensional reality are creating all the 3D shapes we experience just like the the 2D plate forms the 1D lines?

This is awesome - I love seeing the "real" version of a clearly cg thing! that said, this title sequence got my brain going too. for years (probably since I saw your first video about these) I've wanted to build an arbitrary chaldni generator. here are a handful of ways you could do it, playing with boundary conditions, using multiple actuators, driving with more complex waveforms, or in the least-dynamic mode, modifying the sheet's springiness or mass locally, but regardless any of these requires a LOT of math... Since this would necessarily require a huge pile of simulation, I'm curious about your simulated patterns not lining up with the actual ones - did you glean any idea of why/how they failed to predict the nodal lines? My gut would say that the equation assumed the actuator in the center of the plate was the center of a tall antinode but based on your 1d strip example, that didn't entirely pan out?

Really cool! When I first saw the intro to the show I went back and rewatched your old video on Cladney figures - this one is certainly more cinematic :)

This is actually a surprisingly good introduction to many of the topics you would see in a structural dynamics course. This is quite refreshing considering the overall quality of most edutainment-type stuff on KZread. Granted, you left out the derivation of those equations, but that's a graduate-level topic requiring a semester or more of study.

I had forgotten what these were called or that your channel was where I'd learned about them back in the day but I was hoping that one of my educational youtube subscriptions would tackle this and you did it better than I could've hoped for. And the Gollum bit, hahahaha! Thanks :)

I recognize one of these resonance patterns, also in metal, stamped tin ceiling in my house. Crazy part it, house is surrounded on all sides by fright trains in the air. I'm wondering if it had vibration suppressing properties, only a few rooms still have it, but and oddly the plaster survived better in the rooms with the ceiling.

Love your sequence at the end - I too thought of your video when I saw it but assumed it was probably all GCI just inspired, especially when they did those 'trees'.

Once again I am astonished about the thought and work put in this video, bravo! The first time I saw the title sequence I decided to use it as an example for my students. And a few weeks later you give us this perfect video, thank you this will make preparing the lesson so much easier. :)

Best bit of the entire show am I right? 🤣

Wish you would of included the frequency used for each pattern. As regards to your circle pattern, I have found two. I need to find my notebook, will post the numbers when I find it

I've been waiting for this kind of practical explanation ever since the first episode - thank you!

i think the thing to remember with the title sequence is that there's no way to know if they're being shown in reverse or not, therefore they could be setting up a shape they want (such as the rotating spiral) and then vibrate the plate to have it break down and play it in reverse

I’m studying structural mechanics, and no one has explained to me what a boundary condition actually means better than this video…

Amazing video! Thanks for promoting such nice view of science. I was just wondering what could happen if the dimension of the vibrating object was fractal, not an integer but something between 1 and 2, for instance. Maybe one way to test this would be a plate with a couple of holes of different size or having a fraction of the plate being made of a different material. Do you know if there is any study in this direction? Thanks again and success to your channel! I am already subscribed.

This is very similar to the idea behind the Fourier Expansion, and Fourier Series, in mathematics. Essentially, any function can be described as an infinite sum of sinusoidal functions with proper coefficients. Taking the first several terms in the sum is a good approximation of the original function, and is sometimes easier to work with in calculus.

You never experimented with different plate shapes with the vibration generator! I wonder if that one you were trying to recreate from Rings of Power might have been easier on an octagonal plate (or even octagrammal? Is that a word?). You'd also be able to get higher modes if you used a larger plate, since it would have lower resonant frequencies. I also wonder now about other boundary conditions--what if you forced the plate at multiple points, with different phase relations? Or even different frequencies (probably in simple rational ratios like 2:1 or 3:2)? I bet with a whole array of transducers around the edge of a plate, you might be able to use phased-array techniques to put all sorts of patterns on the interior...

Well done! Absolutely the best video recreating something from a video I have seen. I thought it was using Chadni plates the moment I saw it, so this was a real treat to watch.

I loved the Steve Mould intro and backing music. Great way to end the video.

I think more thought went into your video about the title sequence, that the whole script for season one of RoP. Amazing video dude.

Absolutely incredible! I was wondering about that! Thanks!

When I first saw the intro I thought it might be resonant frequencies, but then I figured probably not because of the way the sand moves in those shots. If you watch carefully, in Rings of Power they kind of flow from one spot to the next, whereas in this video you can kind of see them bouncing around randomly until they land on a node. The real life example has a more chaotic feel than the Rings of Power intro.

Speaking of resonate frequencies, my day-to-day vocal range (what I normally sound like while talking) happens to include the resonate frequencies of several plastics and woods so I often vibrate surfaces around me when I talk.

NO WAY I’ve been thinking about this like two weeks in a row and here you are explaining it omg

In the edge-driven setup, you are forcing an anti-node as well by where the bow is in contact with the plate.

the cross sequence also looks like they just drew on the plate with the sand then modulated it to get it to diffuse, with the back and forth motion of the whole sequence it fits right in

Legit the first thing most of us thought of was you when we saw that intro. You are the best.

This is really awesome and the fact that you had done something like this is awesomer.

Steve! Thank you so much. That's exactly what I was thinking, when watching the RoP intro. Neat.

5:23 Desmos is such a good site love it.

Super didn't expect this to come up in one of your videos but I really appreciate your homage to what Is, in my opinion, the best scene of the best character from Lord Of The Rings. Phenomenal

Part of it might be where the material starts. For example if there was a “node” in the middle and no material inward of that “node” or between the “node” or the next “anti node” then surely it wouldn’t collect at the “node”. And then obviously each pattern shifts the material, so it may be possible to create a sequence of patterns that depend on the patterns that come before.

I saw ROP intro for the first time at your video just popped up in my head like a jolt, and i wowwed

Love this video. Thanks for what you are doning Steve

How I imagine it: *someone in the studio planning the intro* "How do we make particles of gold dance or move on their own?" *2nd guy* "What about that old video on Chladni figures by Steve Mould..." *1st guy* "Mould... like the Mould effect?"

Wow!!! That final sequence was amazing!!

Makes me think you can use this concept to travel through space. Where the parts are not moving are the locations in space to travel to

I can tell you had fun making this video, that makes me happy

you can get non uniform patterns by using more than one speaker or resonance underneath with different frequencies. fun stuff to just run random music and see how it forms.

Every time that opening started I thought: I bet whoever made this is a Steve Mould viewer. Also, if any of it was practical effects or it was all rendered.

It's the best part of the séries so far

You made me remember how long I am following you. As always a fantastic video. Thank you for your work 🙏💖
