@@blacklistnr1 I'm not sure I agree with that logic. I find spiderman cool, but even though Superman is a comic book super hero, I find him dreadfully dull. Just because they're related doesn't mean that they're equally interesting
I love this channel, because it doesn't assume the audience knows nothing like most science channels, but it still explains everything clearly in case you don't.
For a while you've been making videos that are honestly some of my favorite on the entirity of youtube! They're niche but interesting and engaging which I find so impressive. They're also sneakily educational which is wonderful. Thank you for the incredible works.
As a kid I once accidentally found two oddly-shaped magnetic rocks while goofing around in my neighbors’ backyard, and I loved them, and they made a similar sound. Sadly I’ve since lost them but I have never forgotten them.
That's also how magnetism was first discovered way back when :) they would've been called lodestones for the longest time. Some cultures highly valued polished and shaped ones, I wouldn't be surprised if they liked the sound too.
@@kaitlyn__Lwould a naturally occurring lodestone have a strong enough field for something like this? I think of lodestones, that they have enough of a magnetic property that they will attract each other, but not enough to really do the same as this. Additionally the lodestones would need to resist any plastic deformation and restore back to their original shape after collision, so I'm not sure a natural rock would have that property either.
@@R.B. most weren’t strong or rigid enough, but that’s why ones as good as this were so highly valued. I’m sure it’s a super small percentage compared to what we crank out, and likely not as loud. But some were highly polished, strong, and jewel-like. They were put into necklaces, brackets, and stuff; I remember seeing a few bracelets in a display (in the Ashmolean Museum if I recall correctly).
Once again you've managed to create an absolutely captivating video about a topic that most people never really think about. I love the pacing of your videos and how you manage to connect two seemingly unrelated concepts in unexpected ways.
I love your video topics. They are simultaneously so disconnected, unpredictable and somehow still carry similar „vibes“. I hope you will be able (want to) continue to explore such unique topics.
Great video! Fun fact, the magnets don't bounce infinitely many times due to the air's viscosity... There is a cutoff for a critical Stokes number (and another characteristic elastic number) for which particles approach one another without rebounding.
@@TeamTechSkatersheat is just the magnets buzzing at a very small scale, so technically, yes, in the classical limit. But also no, heat/sound is actually quantized in solid-state physics, and also, with no air they wouldn't be making noise at all.
@@NXTangl I had replied but I need to investigate your comment about solid-state quantization before I think I make it again. Care to explain so I understand? What I had said before is that heat will still be generated by the exchange of kinetic energy even on the small scale. This exchange excites the atoms and would give rise to temperatures because heat is still incurred, even in a vacuum. To answer woomy's question in an applicable sense, no system is closed, and losses are always expected. If start changing givens, my answer may change
My greatest accomplishment in life will be when I can understand everything being said in physics videos like these. I understood about half of the video so I’m getting closer.
Stuff like this is why so many physicists are also musicians! Understanding harmonics comes far more naturally after you've played with timbres and disharmonic overtones in a musical context. (Which is exactly why I suspect the creator chose this subject!)
Something about this video hit different. They usually feel like you are here to teach me something neat, but this time we were on an adventure to calculate the physics of a random part of life! It was so much more engaging!
As an engineering student my first thought after realizing that the force is inversly proportional to the inverse of the distance, was "Just approximate with a linear function", so when you said you're gonna assume constant force it just got better.
I absolutely love your videos because they're this wonderful combination of niche topics with eloquent explanations and amazing visualizations! Nothing else on UA-cam can come close to these! Thank you!
8:39 it shows vertical lines because the bounces produce pulses, those are clicks that contain a wide band of frequencies. While the pulses repeat at a rate below haas they're perceived as separate clicks and not as a tone, that's why humans don't hear tones below 20hz, we instead perceive it as discrete rapid hits, and the window of the spectrogram is usuallt configured accordingly. Once the frequency of the pulses goes above 20 Hz they enter the window size and the signal can be plotted as a pulse wave of that frequency, with its fundamental and harmonics, just as we can start hearing it as a pitch. It's very interesting!
It wouldn't be perfect. Every material has it's own resonant frequencies which would help sustain some frequencies while muting other frequencies. This is why different shaped rattlesnake eggs sound different. Making real world sounds synthetically is really hard.
As many said, your videos are amazing. One thing I have to mention is about your video on music. The part where you explained why and how certain harmonies sound good for us has a special meaning to me. I experienced this before watching your video, while messing around with sound. Your explanation was kind of a miracle to me.
I used to have a pair of those magnets as a kid that i haven't thought about in almost 2 decades. Amazing video as always, and thanks for the blast of nostalgia!
I'm an Audio Engineer, and I just found a couple of these magnet sets the other day! I'm absolutely going to try to get a higher resolution spectrogram.
Just discovered your channel: love it. You elaborate with simple but clever and effectice animations, and you explain the math behind it without dumbing stuff down too much but pacing it enough that its entertaining even to people who aren't here the check or recreate your work.
One of my Professors once said "that a good theoretical physicist knows what approximations to make, before he knows if he is even allowed to make them." Very nice video highlighting what you can predict even with very simple models.
it would be really interesting to use the equation to synthesize audio waveforms and see how well it matches, plus turn some knobs to generate sounds from preposterous magnets
this is one of the first things i ever modeled when i was first learning programming. i modeled the finite bounces by simply having a threshold for velocity where if the velocity of a ball was below the threshold, the velocity of the ball in the y direction was set to zero, and a different threshold for the x direction. this allowed for separate coefficient of friction and restitution and resulted in super realistic bounces. you can model this very easily though without using any formulas and instead just adding values each frame of a simulation with discrete time. if you make the discrete time steps 25 ms or less, your eye will not be able to see the steps and it will appear continuous. its pretty slick
I really enjoy your videos. I feel like all of them are stuff you fell into a rabbit hole googling then realized you had enough understanding to look into it much further than the average person
Hi I just wanted to say thank you. Recently I went on a trip to Georgia to visit a museum and I bought those magnets. I loved playing with them until I dropped them on the tile in my house and they cracked. When I saw this video it made me so happy
As with all of your videos, this is really good. I have a serious question - have you considered writing some of your projects more elaborately, using error measurements and the usual structure of a paper - and publishing it by yourself?
Dude I watched this high has a kite and while I didn’t understand the math at all; I was thoroughly intrigued and impressed by the quality of this video, well done homie keep doing this!
Olá, sou brasileiro. Adorei seu canal. Seu conteúdo é muito legal e didático. Espero que você continue fazendo mais vídeos e que eles sejam compartilhados. Propagar o conhecimento da maneira que você faz é louvável. Desejo muita sorte e felicidade para você. Abraço.
I'm not a physics guy, but this video was awesome. I liked seeing calculus used! I don't really intend to study and use many physics concepts, but I really respect people like you who can find a question about something and just use them to find the answer.
I was curious what the actual coefficient of restitution those magnets have, to see if your estimation was accurate. To my surprise, not only could I not find restitution coefficient for hematite (what these magnets are typically made of), but I couldn't find it for almost any material. There's only a handful of charts on google that show CoR for common materials, but there's no real go-to repo to find those values. Might be a good/helpful project for someone to work on. Great video by the way!
That's because CoR isn't a property of a material, it's a property of a pair of objects. Think of steel: if you drop a ball bearing on a big steel plate, it's gonna bounce a lot. If you drop another steel plate on top of the steel plate, it isn't.
Man I used to have these and other shaped ones as a kid, haven’t heard or seen anything about them in probably nearly 15 years until this video was randomly recommended
I think he integrated the force over distance to get the work done and equated that to KE. However there is a much simpler way to arrive at that result. F = ma so a = F/m v = at so t = v/a = mv/F But this is the time taken on half of the motion (ex: to stop) so multiplying by 2 gives 2mv/F

I really enjoyed this video! The explanations are straightforward and I really like your use of coding tools for analysis. It really gives the video a “hands-on” sort of feel!
Nice! A very solid analysis with good math! Well executed. It got me thinking about how delta/impulse functions might factor into it. In the early windows of the frequency analysis, where there's only one bounce per window, we can see the impulses as the vertical bars, covering every frequency. I think that the harmonics you see later on might actually be best considered an artifact of the fourier transform operating on a series of impulses occurring at a given frequency. It falls into that weird area of psychoacoustics where we transition from hearing them as separate events and instead hear them as sounds of a given frequency.
Great video! Did notice that you have a slight mistake at the 7:06 mark. The equation for e^n is off, but you used the correct version in subsequent math.
Your channel certainly is an ascending star! Can't wait to see the next video :) Also I love how you drew the magnets. They look like extremely cute eyes
This video was a really strange way to generate money to pay off your student loans that you clearly incurred while learning the very content in the video, but I'm here for it.
I might be wrong, but at around 7:02, shouldn't your top right line be e^n = 1/e[1-t/T0(1-e)] instead of 1/e[1-t/T0(1/e-1)]. This then means that in the formula for f(t), you have e.f0.t(1-e) instead of f0.t(1-e) in the 2nd term of the denominator. I mean, the conclusions stay the same and since e is so close to 1 it doesn't make much of a difference anyways. Great vidéo btw! I hope you keep up the great content
i noticed this too, and yeah it should be (1/e)[1-(t/T0)(1-e)]. it is kinda lucky that 1-e is close to 1/e-1 for e close to 1 tho. edit: apparently he responded ua-cam.com/video/cVGwwO-SMbE/v-deo.html&lc=Ugw_m6NUS5bz98O6RLp4AaABAg

It’s an oxymoron, just shy of infinite also means infinitely far from infinite, funny thought lol.

It wouldn't be perfect. Every material has it's own resonant frequencies which would help sustain some frequencies while muting other frequencies. This is why different shaped rattlesnake eggs sound different. Making real world sounds synthetically is really hard.
Came here to say this. You would have to model the vibration response of a single magnet when struck and layer that over the bouncing response.
