Domino Chain Reaction (short version): geometric growth in action

[@smorris123]

1.5 X each dimension: height, width, thickness. So the mass scales up by (1.5)^3 = 3.375.

This is an interesting video. Having studied integrated circuit design, we use a similar design scheme when designing digital logic circuits. In order to drive a large gate with a small gate quickly, you need intermediate "buffer" gates with increasing size in between. The principles is the exact same as these dominoes.

[@smorris123]

Weight does matter. Ideally, all the dominos would be made of the same stuff so the weight would scale with the volume. In these dominos, we cheated a bit and made the smaller ones out of aluminum and larger ones out of (solid) plywood. Very small wood ones are too light.

[@CelticSaint]

The difference in the time that it took for one domino to hit the next is interesting. It got progressively longer. I wonder how long it would take for all the dominoes to fall, right to the the Empire State Building sized one. There must be a mathematical equation or something.

[@smorris123]

+Celtic Saint Indeed. It scales like sqrt(H/g) where H is the height of a domino and g = 9.8 m/s^2 is the acceleration due to gravity. As H increases by a constant factor, so the time increases by the square root of that factor.

[@CelticSaint]

[@smorris123]

No. But only a rough match of densities is good enough at a ratio of 1.5. In a really detailed analysis, all these factors need to be taken into account. It depends if you want a sure-fire demonstration that always works, or one that pushes the limits. 1.5 is pretty much sure-fire.

[@gensandwich8156]

The drop was soo loud it made your shoulders stay up for the whole video

[@smorris123]

@MaxXimumPain Each domino is 1.5x the *size* of the previous one. That is, it is 1.5X higher, 1.5X wider and 1.5X thicker. So the *mass* ratio is (1.5)^3 = 3.375. Each successive domino *weighs* more than three times the previous one. You can look up the original paper by Lorne Whitehead to get the full calculation.

[@mehedihassan8944]

Energy can't be created or destroyed.so how I am getting a lot of energy from spending a little bit?

[@smorris123]

This analysis is too simple. As the domino topples, it releases gravitational potential energy and coverts it into kinetic energy. This potential energy was stored when the domino was set upright. There is also significant energy dissipated by friction as the smaller domino slides down the front surface of the next one. See arxiv.org/abs/physics/0401018 for a sophisticated discussion.

[@davmar9696]

@zachgamer77 also due to the fact that the dominoes take energy to put upright, that is potential energy that is stored for later (i.e when the chain reaction begins)

[@smorris123]

@LudicrousTachyon That's an interesting idea. A nanoscale domino would stick to the one ahead of it by the van der Waals force. It would also have trouble with Brownian motion! At the other end of the scale, really large dominos have trouble staying together as they topple. They need to be extremely strong, or they break while falling over. A domino the size of a building would fall almost straight down, like demolished buildings do. See the related video by Gerrydomino.

I don't think there is a standard size. One of the dominos in this set is about the size you would expect for a normal domino. All the others are scaled in all dimensions by powers of 1.5 from that one. The exact dimensions don't matter much: it will work anyway.

[@domino324]

videouploader1677721 actually he said "about one and a half," which in this case would seem to suggest it's more than 1.5 times, not exactly 1.5.

[@mickesmanymovies]

He clearly stated that the first domino was 5 millimeters high, but - as domino324 said - he never locked down the size increasing to be exactly 150%. So if you change the other parameter (increasing size) instead of the size of the first domino, all you gotta do is tweak the numbers a tiny little bit. Even adding as little as 0,05 to the ratio gets you reasonably close to a meter (961,5 mm).

Of course "energy is conserved". What I meant by *available* energy was the stored energy of each successive domino. The gravitational potential energy of a domino does nothing until that domino gets hit by the one before it. Then the stored energy is released to be converted into kinetic energy as it falls. Some little bit gets used to push over the next domino and most of it is dissipated into heat when the domino hits the floor and stops moving (an inelastic collision).

@TheRimDoctor every object stores gravitational potential energy, which must be released before it does anything. when a domino falls it releases that energy. the first domino causes the energy in the next domino to be released, and the energy in that one causes the energy in the one after that to be released. the energy from the first one is terribly small compared with the last block, and it can't do anything on it's own, but it triggers the release of the potential energy in the larger blocks

[@kashskitchen7178]

“OW MY TOE!”

[@smorris123]

@thekeyring Better watch the long version. The energy is stored when you stand up the dominos. Knocking them over releases the stored energy.

a physical representation of the butterfly effect

[@mickesmanymovies]

No... This is a physical representation of the Domino Effect (one thing causes a bigger thing to happen, which causes a bigger thing to happen, which causes a bigger thing to happen, and so on and so forth). The butterfly effect is more on the lines of connecting everything, regardless of size and/or importance of the event happening. Meaning, one thing cause another seemingly unrelated thing to happen, which in turn cause another seemingly unrelated thing to happen. Because of this it is almost impossible to find a real life example of the butterfly effect.

[@22progre77]

@gimkilo57 It doesn't create a bunch of energy, the energy used to push down the last domino was the gravitational potential energy from the preceding dominoes.

[@BakaGaijinSama]

>physics video >not using SI units If im seeing this right, this is what is happening: The first domino is knocked out of equilibrium, it converts GPE to KE, gaining enough energy from gravity to be able to knock the next domino out of equilibirum. It's interesting I suppose, but doesnt seem to be useful, unless you can find some way to reset the dominoes and use the angular acceleration with a generator. Which will likely be inefficient. Still, had me thinking for a min or so :p.

[@PrincessFunni]

00:54 boom

[@edancoll3250]

The smallest domino can theoretically knock over a 15 meter high domino, assuming the big one is unstable enough (meaning its center of mass is close enough to the edge of the base it is standing on). There is nothing special about the number 1.5 here. It could have been 2 or 3 as well.

[@henkbanaan]

it's fairly easy what happens. the first domino, with low mass. gets a certain amount of kinetic energy, which is transferred to the next domino as it hits it. this amount can, in the easiest way, be described with Ekin = 0.5*mass*(velocity^2). this kinetic energy stays the same, so in order to maintain the same amount of energy, when the mass is getting bigger, the velocity has to become lower, as you can see ;)

It has nothing to do with the golden ratio. You could, if you wanted to, build dominos with golden dimension ratios. But they would be pretty much the same as these with ratio 1.5.
