“A network is a set of items, which we will call vertices or sometimes nodes, with connections between them, called edges. Systems taking the form of networks (also called “graphs” in much of the mathematical literature) abound in the world.” (p. 2) #Newman #network #system
“In particular, fundamental problems related to universality could be tackled, both for confine systems where the theory of dynamical systems is relevant (chaos and transition scenarios, e.g., the subharmonic cascade) and for extended systems where statistical physics is an appealing framework (Ginzburg–Landau formalism and nonlinear pattern selection, space–time intermittency and directed percolation).” (p. 61) #Manneville #universality #system #chaos #transition #StatisticalPhysics #percolation
“Daher ist auch das Zusammenziehen der Differenz in einen einzigen Akt der Liebe nicht möglich – oder genauer gesagt: immer möglich, aber nur in der Ewigkeitsperspektive des Moments.” (p. 220) #Luhmann #Liebe
„In real nature, generative as well as generational, no system is ever closed.“ (p. XIV) #Bühlmann #nature #system
„[T]he evolution of the system has a certain stochastic character which is not due to external noise sources, but which is an intrinsic consequence of the non linearity in the hydrodynamic equations.“ (p. 9f.) #Gennes #system #noise
