Multiscale modeling phenomenological model

Nuclei and Below. We conclude our series of historical examples of effective theories and multiscale modeling with a brief mention of the hierarchy of theories which present themselves in considering the subatomic world. Our first remark applies to most of the examples we have presented and it is to note that one man s microscopies is another s phenomenology. Nowhere is this more true than with the history of our exploration of the subatomic world and, in particular, the series of theories that have been set forth to explain what has been observed. The key point is that at each level of structure, the subscale structures can be ignored. For example.
