Abstract: The general features of the onset of spatiotemporal chaos observed in several physical systems are reviewed with special emphasis on the statistical properties. The possibility of constructing a thermodynamics of spatiotemporal chaos is discussed by considering an experiment on thermal convection. It is shown that, by analogy with a system near thermal equilibrium, it is possible to define two quantities, which behave like an energy and an entropy and are related by standard thermodynamic relationships. The fluctuation-dissipation is also verified.
