Abstracts: From the fractal spectrum of spin glasses chaos, a complexity classification system has been developed and demonstrated with cross-geographical intercultural music and brain electroencephalogram signals. [1] Systematic structures have emerged. Chaos under scale change is the main feature of spin glass order under disorder [2,3] and can be found with any degree of chaos from the exact solution of Ising models with renormalization group on depressed hierarchical lattices.
