Abstract

Evolutionary physics studies the general behaviour of non equilibrium systems, subject to non-linear rules. Through the observation of these systems, physical chemistry begins to understand phenomena that have complex and selforganising behaviour. In practice, in order to understand life and its ability to self-organise, evolutionary physical chemistry studies phenomena which present novelties, i.e., in which order is horn from chaos (order out of chaos is an expression dear to the school of Ilya Prigogine, father of evolutionary physics and winner of the Nobel Prize in Chemistry in 1977). This paper presents a discussion on self-organization processes in dissipative structures, in order to highlight the general conditions for raising complexity and generating order in nature. In particular, variation of entropy and thermodynamic information in self-organizing systems were briefly introduced. Examples of dissipative structures in nature were presented, such as oscillatory reactions, hurricanes, and also human society. This would inform next generation designers. Keywords: dissipative structures, entropy, information, non equilibrium thermodynamics, Bènard Cells, hurricanes, cities. 1 Introduction A Dissipative Structure is a thermodynamically open system operating far from thermodynamic equilibrium, that exchanges energy, matter, and information with the external environment. In this kind of systems, organization can emerge through a spontaneous self-organization process, by virtue of the exchanges with the external environment, that generates a formation of both spatial and temporal
