The Thermodynamical Arrow of Time

  • H.-Dieter Zeh

Abstract

The thermodynamical arrow of time is characterized by the increase of entropy according to the Second Law, usually formulated as
$$\frac{{dS}}{{dt}} = {\{ \frac{{dS}}{{dt}}\} _{ext}} + {\{ \frac{{dS}}{{dt}}\} _{\operatorname{int} }}\;with\;d{S_{ext}} = \frac{{dQ}}{T}and{\{ \frac{{dS}}{{dt}}\} _{\operatorname{int} }} \geqslant 0$$
