Examplesodel can also be interpreted as a non-linear generalization of the wave equation. The interest of the model is that, even at the classical level, it has stable solutions with a possible particle interpretation..相反放置 发表于 2025-3-24 02:03:06
Spontaneous Symmetry Breakingo made possible the unification of weak, electromagnetic and strong interactions in elementary particle physics. Philosophically, the idea is very deep and subtle (this is probably why its exploitation is a rather recent achievement) and the popular accounts do not fully do justice to it.轿车 发表于 2025-3-24 02:21:50
