The Essence of Chaos

By Edward N. Lorenz

Book Overview

Chaos surrounds us. Seemingly random events -- the flapping of a flag, a storm-driven wave striking the shore, a pinball's path -- often appear to have no order, no rational pattern. Explicating the theory of chaos and the consequences of its principal findings -- that actual, precise rules may govern such apparently random behavior -- has been a major part of the work of Edward N. Lorenz. In The Essence of Chaos, Lorenz presents to the general reader the features of this "new science," with its far-reaching implications for much of modern life, from weather prediction to philosophy, and he describes its considerable impact on emerging scientific fields.

Unlike the phenomena dealt with in relativity theory and quantum mechanics, systems that are now described as "chaotic" can be observed without telescopes or microscopes. They range from the simplest happenings, such as the falling of a leaf, to the most complex processes, like the fluctuations of climate. Each process that qualifies, however, has certain quantifiable characteristics: how it unfolds depends very sensitively upon its present state, so that, even though it is not random, it seems to be. Lorenz uses examples from everyday life, and simple calculations, to show how the essential nature of chaotic systems can be understood. In order to expedite this task, he has constructed a mathematical model of a board sliding down a ski slope as his primary illustrative example. With this model as his base, he explains various chaotic phenomena, including some associated concepts such as strange attractors and bifurcations.

As a meteorologist, Lorenz initially became interested in the field of chaos because of its implications for weather forecasting. In a chapter ranging through the history of weather prediction and meteorology to a brief picture of our current understanding of climate, he introduces many of the researchers who conceived the experiments and theories, and he describes his own initial encounter with chaos.

A further discussion invites readers to make their own chaos. Still others debate the nature of randomness and its relationship to chaotic systems, and describe three related fields of scientific thought: nonlinearity, complexity, and fractality. Appendixes present the first publication of Lorenz's seminal paper "Does the Flap of a Butterfly's Wing in Brazil Set Off a Tornado in Texas?"; the mathematical equations from which the copious illustrations were derived; and a glossary.

Great review of chaos by one of the founding fathers

Edward Lorenz is credited with "discovering" chaos theory based on his meteorological work. In The Essence of Chaos, Lorenz does a great job describing the historical background of chaos theory and its implications for the natural world. Well-written with some interesting graphics.

Very Good Introduction

I read this book when it was snowing outside in the Sierras. I was immediately able to correlate this book with the chaotic snow fall. Extremely good read.

Excellent Chaos Primer

My first intro to chaos was Gleick's book *Chaos: Making a New Science* which focused on the history of the discovery of chaos. Although this was fascinating - and a good read for those just learning about dynamical systems, strange attractors, and the like - Lorenz's *Essence of Chaos* was much more satisfying. Lorenz analyzes specific chaotic functions, gives you the math (equations are in the appendix) and generally accomplishes what the title suggests - that is, exploring the essence of chaos. I highly recommend it for anyone interested in this deeply fascinating subject.

Great Stuff from the Great One

Lorenz has done it again. This is a terrific inside look at chaos by the man who made Gleick's book possible. And it had a few interesting new ideas too--who would have thought there was a different way to present fourth-order Runge-Kutta? Who would have thought Runge-Kutta could convert a phase-space circle to a nice-looking fractal attractor? A good book for the air plane.

The Essence of Chaos: A great primer on chaos theory.

Edward Lorenz takes a complicated topic and makes it accessible for all people, regardless of prior knowledge of chaos theory. He provides interesting and easy to follow examples of chaos, fractals and complexity. The illustrations are helpful and he includes a glossary of terms to aid the beginning chaos enthusiasts to quickly become familiar with the terminology. Mr. Lorenz gives a brief history of chaos and explains how it is used in the study of mathematics, meteorology, economics, music, and other fields. The book is very interesting and is highly recommended for those who would like to acquaint themselves with the exciting world of chaos.
