Brownian motion and microscopic chaos

Article Abstract:

Random evolution of a process over time, known as macroscopic chaos, has been observed in many systems, despite the characteristics of their dynamics. It has been assumed, although not proved, that chaotic microscopic motions of the molecule's constituent atoms are responsible for the phenomenon. A new study of a fluid system provides the first evidence of chaotic dynamics in the form of brownian motion of a colloidal particle suspended in water.

Engineering complex systems

Article Abstract:

The complex system, which includes metabolic pathways, ecosystems, the web and the propagation of HIV infections, is discussed. The features of complex systems, adaptation, self-organization and emergence are in conceptual conflict with the engineering terms.
