# Moderate Degree of Input Negative Entropy Flow and Decrease of Entropy in Astrophysics, Biology, Psychology and Social Systems

@article{Chang2009ModerateDO, title={Moderate Degree of Input Negative Entropy Flow and Decrease of Entropy in Astrophysics, Biology, Psychology and Social Systems}, author={Yi-Fang Chang}, journal={arXiv: General Physics}, year={2009} }

Thermodynamics have been applied to astronomy, biology, psychology, some social systems and so on. But, various evolutions from astronomy to biology and social systems cannot be only increase of entropy. When fluctuations are magnified due to internal interactions, the statistical independence and the second law of the thermodynamics are not hold. The existence of internal interactions is necessary condition of decrease of entropy in isolated system. We calculate quantitatively the entropy of…

A method of statistical analysis alternative to the compression procedures is introduced, with which the limitations of the traditional Kolmogorov-Sinai approach are bypassed, and it is proved that this method makes it possible to build up a memory detector, which signals the presence of even very weak memory, provided that this is persistent over large time intervals.
