2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

TURING STRUCTURES 1)2)

← Back

Emergent heterogeneous structures in a homogenous distribution of chemicals.

In his 1952 paper on "The chemical basis of morphogenesis", A. TURING showed that some chemicals, homogeneously distributed at first, may, by reactions and diffusion, lead to variations in their local concentrations, i.e. to heterogeneity, and form spatial structures.

This has been experimentally verified. As an asymmetry creating mechanism (rediscoved in 1976 by H. KUHN), it has a very general explanation power for the morphogenesis of complex systems, based on simple evolution rules.

As a result, similar dynamic behavior or structures may be found in very different systems, as for example in vegetal helixes (S. DOUADY and Y. COUDER, 1993).
