It is interesting that such humps exist at all. People once doubted their existence.
Solitons have practical applications and they are also interesting subjects of theoretical study.
This is known as superposition. On the one hand, we hope to be able to use solitons to better understand real particles. However, there is so far no general theory in which particles are described as solitons. Still, there are macroscopic phenomena, such as internal waves on the ocean, spontaneous transparency, and the behavior of light in fiber optic cable just to name a few, which are know understood in terms of solitons. This has been used to the benefit of each subject.
