“It becomes complex if things do interact, particularly in the case of “nonlinear” interaction.”

— Pearl Zhu

In complex systems, one can think about linear interactions and complex or nonlinear interactions.

— Zeynep Tufekci

The relations that define a system as a unity, and determine the dynamics of interaction and transformations which it may undergo as such a…

— Francisco Varela

The way to build a complex system that works is to build it from very simple systems that work.

— Kevin Kelly

“profoundly complex systems”

— William Brinkley

“a system must consist of three kinds of things: elements, interconnections, and a function or purpose.”

— Donella H. Meadows

The only way to know how a complex system will behave-after you modify it-is to modify it and see how it behaves.

— George E. P. Box

Complex systems are hard to understand, predict and control.

— Dominic Cummings

“It’s a simple complex system. That’s the technical name for it. Because it’s simple, it’s prone to cascades, and because it’s complex, you can’t…

— James S.A. Corey

“Linearity is a reductionist’s dream, and nonlinearity can sometimes be a reductionist’s nightmare. Understanding the distinction between linearity and nonlinearity is very important and…

“Because of their composite nature, complex systems can exhibit catastrophic behavior.”

— Per Bak

A system is a set of things people, cells, molecules, or whatever interconnected in such a way that they produce their own pattern of…
