Non-Equilibrium Dynamics, Biological Systems and Time-Arrow

Pp. 184-195 (12)

Jacques Ricard


The concept of time-arrow does not appear frequently in physics. This is not the case for the study of biochemical systems as many of them are able to sense whether a variable is increasing or decreasing. This effect can be explained by the non-linear character of the system and its dynamics.
