What phenomena are related to chaos?

For example, it can be found in weather change, fluid movement and biological evolution. Because of the randomness of chaotic system behavior, as mentioned above, it is impossible to predict the long-term behavior of the system. However, because the system behavior is determined by certain deterministic factors and their laws, it can be predicted in a certain period of time. Scientists hope that through the in-depth study of chaotic phenomena, some scientific problems can be better solved. For example, the beam loss in the high-energy particle accelerator, the leakage of magnetic confinement in the beam-controlled thermonuclear reactor, the possible harmful backflow in the circulating water system of nuclear power plants, the weather forecast, the choice of boys and girls for human beings and so on. , all related to chaos.
