The Fermi Paradox, Phase Changes and Intergalactic Colonisation

A new model shows how the spread of ET civilisations can undergo phase changes, providing a deeper insights into the Fermi Paradox.

Chemistry Drives Convection


Stirring a mixture can accelerate chemical reactions between the ingredients, but less obvious is the reverse: reactions can stir up a mixture. As a demonstration of the chemistry "tail" wagging the fluid dynamics "dog," researchers have run several computer simulations and verified their model with a simple acid-base experiment. Described in the 29 January Physical Review Letters, the results explicitly show how common chemical reactions can induce fluid flows.

Self-similarity properties in a queuing network model

In this paper a model of subscriber telephone network based on the concept of cellular automata is elaborated [1]. Some fractal properties inherent in the model are revealed that vary depending on parameters assigning its operation rules. The main advantage of the model in question is its compatibility with algorithmic methods - a finite set of formal rules, assigned on a finite set of elements (cells), allows precise realization in the form of algorithms.
