International Encyclopedia of Systems and Cybernetics

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.

BELOUSOV – ZHABOTINSKII REACTION 2)5)

← Back

"A complex chemical reaction involving the cerium-catalyzed bromination and oxidation of malonic acid by bromate ions" (J.S. TURNER, 1982, p.48).

A now famous chemical reaction, whose relation to nonlinear systemic processes studies is thus described by TURNER: "The great interest of the Belousov-Zhabotinskii (BZ) reaction lies in its unique ability to exhibit a wide variety of characteristic nonlinear behavior. Ranging from homogeneous chemical oscillations in stirred reactors to travelling chemical waves and stationary spatial structures in unstirred mixtures, the phenomena observed in this system include all the types of nonequilibrium coherent structures that have been studied theoretically in the past decades. In the last few years, besides, new experiments have suggested that the same chemical processes which give rise to coherent phenomena may also yield incoherent or chaotic behavior as well" (p.48).

The BZ reaction is an example of a reaction-diffusion system, resulting from the competition of a force that tends to produce dissipative structures and another that tends to dampen them out.
