Domino effect:

Or Domino Effect (Domino Effect), which refers to the fact that in an interconnected system, a small initial energy may produce a series of chains. reaction. The domino effect is a psychological effect, similar to the butterfly effect, which refers to a series of chain reactions triggered by a small initial energy in an interconnected system. This effect is widely used in many fields. , used to explain some related phenomena. Its extended meaning means that the final result of a good practice is good, and the energy that is beneficial to all things is respected by all the world; the final result of a bad and destructive practice is bad and irreparable tragedy and consequences.

The chain reaction of dominoes reveals the chain reaction of seismic waves:

In seismology, the shock wave (hypocenter) is the cause of earthquakes. When the dynamic waves generated by the underground layer reach the rock layer , these powerful fluctuations cause rock faults to begin to crack and collapse, causing the surface to crack, collapse and shake. Earthquake energy accumulates and releases to the surface, causing surface buildings to shake and collapse. Rock layers are like neatly arranged playing cards, building blocks or dominoes. In an interconnected system, a small initial energy may produce a series of reactions. People call it the "domino effect".

Physical analysis:

The physical principle of this effect is: when the ancient card is upright, its center of gravity is higher, and when it falls down, its center of gravity drops. After the falling process, its gravitational potential energy Convert it into kinetic energy and pour it into the second card. The kinetic energy is transferred to the second card. The second card converts the kinetic energy transferred from the first card and the gravitational potential energy it has in the process of falling. The sum of the kinetic energy is then passed to the third card...so when each card falls, it has greater kinetic energy than the previous card, so the speed is faster than the previous one, that is to say, they are knocked down in sequence. The energy of each one is greater than the other.

Experimental introduction:

Domino is a rectangular ancient card made of wood, animal bone or plastic. When playing, arrange the ancient tiles in a row at a certain distance, and gently knock down the first domino, and the rest of the ancient dominoes will have a chain reaction and fall one after another.

Placement method:

The ancient domino cards themselves have about 8 colors, which are generally called "basic colors". These basic colors are all solid, and a crucial step in creating a beautiful pattern is to color the dominoes.

There are two methods of painting: one is to use a brush dipped in paint to paint on the ancient plaques. This painting method is mostly used to paint single colors. Sometimes an ancient plaque requires multiple colors. In this case, a special pen called Poska is used, and the paint is actually a kind of paint. Finally, before removing the ancient tiles, the side facing outwards of the ancient tiles should be painted in a more uniform color.

Another key step is stacking. Although there are some tools that can stack more than a dozen ancient plaques at once, the ancient plaques in many places still need to be manipulated one by one, sometimes even using tweezers and other tools.
