I expected the hardwood to be faster than the felt because the rotational moment of inertia when spinning around the center is 1/4th that of tipping on the edge. I was wrong in this case, but I'm wondering if this would hold true on glass?

@IntellectualKetchup
@IntellectualKetchup 5 лет назад
Unfortunately, gravity is still a mystery and as a whole has not been proven to be fact. Science advancement in physics has been held back compared to many other sciences, because so much is based on guesswork that has never been proven via experimentation. Most people don't know that we have never actually seen inside an atom, and since we don't have the ability to travel into "outer space", everything there is all unproven theory as well. In fact, as Michio Kaku said, it is the biggest disconnect between theory and scientific experimentation, in the history of mankind. The fact that the Earth's movement has never been proven, and there are so many actual scientific experiments that prove the opposite, makes me wonder why academia can't get their head out of their arses. It is ok to admit that you have no clue how this realm works. If all of mankind was aware of the fact that we live inside a realm, with a flat plane at the center, science could make some great advancements. I recommend watching the Primer Fields series on youtube. Also watch, Flat earth is Scientific and the Globe is not, by the Mr Astrotheology channel.

@hammerslap5639
@hammerslap5639 6 лет назад
I am wondering if you tighten up a few controllable variables you may improve some of the predictability and get some tighter numbers. 1. You are initiating the dominoes with a flat sided ruler pushed by hand. This could easily cause variables in the initial rotation of the dominoes and could introduce a more pronounced wave in the pattern of "rotating" dominoes to the "slam" dominoes. Doing it by hand could also introduce a greater or lesser initial momentum that gets carried through the whole set. Maybe initiate the dominoes with something like a spring fired pin that strikes the initial domino it the same spot and at the same speed every time. 2. Surface variables - For the hard wood there are going to be many variations from board to board that could possible effect results from run to run. Differences in grip from board to board, wood grains, the small gaps between boards. Looking at your graphs you see a moment where the hard wood actually accelerates to a speed greater than the felt before correcting back down. might be from a slightly higher traction on 1 board before correcting back down on a more slippery board. Felt can have an entire set of its own differences that could effect the dominoes on the other side. I'm thinking something like a long piece of class would be a good surface to do the "slick surface test" and possibly a long strip of rubber mat would be good for the "High Traction" test. 3. For ultimate comparison, I remember they used to have domino sets where it was plastic rails that each had 10 or so dominoes affixed, I think they are called pivot track dominoes... you would place these tracks of dominoes end to end to make your full run. You would have a run where every domino was in the exact same order facing the exact same direction running on a "constant fricktion surface". A good run of these affixed to a board to ensure consistent spacing between tracks, fired with a pin to ensure exact starting velocity, should give a somewhat "variable-less" run and may show once and for all if you can or can't predict the fall speed of a particular run of dominoes. In either case, I love domino videos and I love your videos so maybe I am just being picky so I can see you make more domino videos.
@theHOONeybadger
@theHOONeybadger 6 лет назад
I am going to "BUMP" this comment, because questions 1 and 2 are exactly what I was thinking. 1 - I do however think the flat push approach would work better, just automated with the same timing and pressure each time. If you had a pin point push, it would have to hit precisely in the middle (side to side), or it could initiate a twist right away. 2 - especially on a basketball court, the slickness of the court could be vastly different if you set one domino on say, a shoe scuff mark for example. I was wondering how clean the surface is, as well as how smooth it is. With wood, you can always get variances in the surface smoothness (whether it be the varnish, or the wood itself warping slightly), and since we are talking in such a minute scale, this could affect the outcome. I like the piece of glass idea for a more consistent surface texture. Thanks Hammerslap for typing most of what I wanted to say, haha!

@andreaskerscher235
@andreaskerscher235 6 лет назад
I also totaly agree on reducing the variables. But using affixed dominos would be something completely different, because they are not able to slip at the bottom. I agree that it would be good for a comparison because they can not twist either. So they should - in theory - fall at a constant speed after an acceleration phase.
@hammerslap5639
@hammerslap5639 6 лет назад
using the affixed dominoes would eliminate the "slippage" variable. which would help us know if the fall is consistent from run to run. once we see that it is reasonably predictable that way we can prove predictable deviation based on surface.

@TheCgOrion
@TheCgOrion 5 лет назад
Absolutely. Not just in how it twists, or the bottom shifts, but the amount of energy she adds into the system, completely changes how each interaction reacts.
@sreramk1494
@sreramk1494 5 лет назад
True, but even if you are very careful about how you push the dominoes, the part of the energy that gets transferred to the twists from the translatory motion depends on factors like the roughness of the surface the dominoes are placed (for example, if the left side of a single domino is more rough than the right side, then it is more likely to twist from right to left, anti-clockwise). For some reason, the energy from the twists start to transfer to the translatory motion, and this oscillates back and fourth. It does depend on how it was pushed, but the outcome cannot be predicted with just that. There are millions of other variables involved, which eventually obscures the initial conditions to the extent that it cannot be traced back. Thus, regardless of the initial conditions, the outcome will always be random. That's why it is "chaotic".
@bclamore
@bclamore 5 лет назад
Yes, the initial push is a variable. But, as mentioned in the video, the system has a self-regulating behavior, which tends to limit the significance of the initial conditions.

I'm pretty sure the clear dominoes would fall faster. The guy from 3brown1blue already showed us the data explaining how dominoes on felt generally fall faster than dominoes on wood, so from they we can conclude that a higher force of friction between the dining and the floor results in a greater velocity. Friction forces are also directly proportional to the weight of an object, so the heavier domino should have more friction, therefore falling faster

@chaoaretasty
@chaoaretasty 6 лет назад
Not quite, there's two things at play here. On one level the difference between a first and a second approximation. At both levels you can extract useful information but without throwing away the second approximation noise you can't see the minor speed difference from the moving average. On another is context. Yes there's peaks that look like a pattern but without the context of the slow motion itself the runs aren't long enough to say that those peaks are genuinely a pattern rather than just noise. With the slow motion as well you can see the twists and align it with the peaks as Destin did and have a physical basis for the pattern.

Yo Destin, Physicist here! This video was awesome, but I've got one question to ask: have you got any error bars? A standard rule of experimental physics is that data are useless without knowledge of their uncertainty. In particular, the v-t graph that 3Blue1Brown had seemed like addition of error bars would help the analysis. Without them, it's impossible to tell whether your conclusion that one goes faster is truly valid, or if you can't reject the null hypothesis.

I think it is a mistake to look at this data in a time domain. Why not take a fourier transform of the data, that would certainly confirm or deny to show the frequency of the 'twist-slam' phenomena you mention. Just random distributed 'white' noise has a noise spectral density that is constant, so if there is a cycle it will show up as a peak in your frequency spectrum.

Alternatively, a time series analysis would reveal things like how the fall time of the current domino effects (predicts) the fall of successive dominos. The twist phenomenon might manifest as "seasonality" which indicates there is a cyclic trend. There are lots of cool ways of mining this data.

I would have expected slipping would be faster, because the moment of inertia is lower. But I guess more energy is directed forward when it doesn't slip... Heavier dominoes would have a higher moment but also more stored energy, so I don't know what would win. Might be fun using dominoes with different mass distributions, i.e. light dominos with high moment (weight on ends) and heavy dominoes with low moment (weight in middle). Interesting how it seemed to reach a terminal velocity.

I wonder how if the sound signal of the dominoes is loud enough to make trough the sound of the camera rig to a basic mic or if it will ask for a more sensitive model, like a shotgun mic. It will help a lot with the frame trace since you can sync the mic with the camera using a sharp sound on the start. Trying to make a clear sound/vid shot will get more sensitive but may payback well

@orbik_fin
@orbik_fin 6 лет назад
Not a bad idea but it would be really hard to extract useful information out of it, because: 1) The dominoes make more than 2 hard collisions each and the one you're most interested in isn't necessarily the loudest one. 2) Tracking the toppling with a highly directional mic is even more challenging than with a camera. If the mic isn't very directional, you'd get extra noise from the previous dominoes still tumbling down. 3) If tracking isn't perfect you get a measurable amount of doppler shift, possibly distorting the result. 4) You'd probably want to do this in a minimally reverberant room - not cheap if you also need ample space to move around. Also, the high speed camera already records video at effectively audio rates.

The sound of the falling dominos is amazing! Here is what I noticed while watching slow-mo videos: Small objects seem to behave exactly like large ones, but way faster. Or the other way around: If you slow down fast movements of small obects, the behavior shows the exact same over all appearance of large objects. (E.g: the small and therefore light dominos sound an fall like big, heavy stones, when shown in slow-motion) Is this phenomenon adaptable to every (macrophysical) occurence?

@trulyUnAssuming 6 лет назад
The issue is: you record an audio strip with an audio wave. Now you want to play that slower. But if you use the same audio waves and play them slower, that means that you reduced the frequency of the sound. Which means everything sounds lower. That is why if you play a youtube video faster now it would correct for that such that the voices don't suddenly sound different. So is the higher or the lower sound the correct sound?
@ItsJustGilly
@ItsJustGilly 5 лет назад

After watching this it is clear that there is way more happening here than one would have thought. I was actually captivated by how they twisted and how that twist was self correcting until it was nullified only to return a few down the line. Amazing video show how simplified questions can lead to intriguing discoveries.

Hey Destin. I just watched this domino/physics video. I am a practical application engineer/carpenter/mechanic/designer/teacher/musician. As I watched your observations my thoughts wandered back to when I was a child in the 60s. Space and physics have always amazed me. Here are a couple of considerations. 1. Gravity 2. Earth's rotation 3. Gyroscopic reverberation 4. Concusive reaction 5. Rebound 6. Sonic frequency Ok, so there are more than a couple. Ha ha ha... A part of the baseline to consider must be dominoes of different materials to observe the variables in reactions. For example: You used clear acrylic dominoes. What about the standard ebony (black wooden) type or dense white plastic, marble, aluminum, stainless steel, and so many others that dominoes have been made of. My observations caused me to think about so many of the variables and even counter-variables such as momentum responding to the impact which in turn reacts to the vibrations caused by the impact becoming a completely different and opposing force causing the tiles to walk backwards while still falling forward. The noise on hardwood clearly allows far more reactions to be seen as compared to the felt which as you said muted and provided traction, but in turn provided a different set of reations. I realize that there millions of tangents presented here; however, my first thought was frequency. As in vibrational reaction and responses. Starting with the initial contact each successive contact is altered by every physics law applied all at once and varied by each individual response and following reaction. The acrylic material is a highly melodic type of material in other words, it conducts high moving frequencies and sound vibrations. Think of dropping an 8 foot long 2x4 on a concrete floor. The board will hit the floor, bounce, make a sound, and all the while it will be vibrating at differing frequencies throughout it's length from end to end. The length and width will obviously influence all of those responses and reactions accordingly, along with density and weight. Of course this is just one set of variables. Other variables like reflex, rebound, sound waves, and so on.... Hopefully you and your physics enthusiasts can see the amazing possibilities presented here.
