Even in the simplest conditions which naively would lead to the complete "death" of any dynamics, these 2 properties lead to the emergence of self-organized adaptive collective objects. In turn, these objects insure the survival of a very rich and unexpectedly resilient macroscopic "life".Statistical Mechanicstext
