Bigger Than Chaos Understanding Complexity Through Probability [Unknon]

Many complex systems--from immensely complicated ecosystems to minute assemblages of molecules--surprise us with their simple behavior. Consider, for instance, the snowflake, in which a great number of water molecules arrange themselves in patterns with six-way symmetry. How is it that molecules moving seemingly at random become organized according to the simple, six-fold rule? How do the comings, goings, meetings, and eatings of individual animals add up to the simple dynamics of ecosystem populations? More generally, how does complex and seemingly capricious microbehavior generate stable, predictable macrobehavior?

In this book, Michael Strevens aims to explain how simplicity can coexist with, indeed be caused by, the tangled interconnections between a complex system's many parts. At the center of Strevens's explanation is the notion of probability and, more particularly, probabilistic independence. By examining the foundations of statistical reasoning about complex systems such as gases, ecosystems, and certain social systems, Strevens provides an understanding of how simplicity emerges from complexity. Along the way, he draws lessons concerning the low-level explanation of high-level phenomena and the basis for introducing probabilistic concepts into physical theory.

This book is a model of clarity, at both the 'macro' and the 'micro' levels; the expository style is entertaining without being distracting; the presentation of technical material shows the deft touch of someone who has mastery of it without the inclination to overindulge in it.This impressive book tackles an important question: how can systems of many interacting parts, which thus display low-level complexity, give rise to high-level simplicity? Said another way: how can very complicated and seemingly capricious micro-behavior generate stable, predictable macro-behavior? Complex systems of the sortStrevensdeals with are all around us. Thermodynamics and ecology are just the beginlC&
