Emergence and complexity

est 35h · logged 0h · started — · touched —

The thing that makes information interesting: emergence and complexity, from Anderson's More Is Different through chaos theory and the Santa Fe Institute to the current frontier (causal emergence, scaling laws, networks). Needs a critical posture — weak emergence, strong emergence, and emergence-as-mysticism must be kept distinct.

next action

done when you can

Distinguish weak, strong, and pseudo-emergence cleanly.Explain one concrete case of emergence in detail (phase transitions, flocking, ant colonies, neurons → cognition — pick one).Name what Santa Fe Institute actually does, and what "complexity science" means as a methodology.State one concrete result from chaos theory (sensitive dependence, universality via Feigenbaum constant, strange attractors) in your own words.Articulate why Anderson's "More Is Different" is still contested 50 years later.
