Maximum entropy9/15/2023 ![]() ![]() The extension of the concept of entropy to complex networks would therefore provide a useful tool to study and understand the evolution of systems, especially strongly interactive systems like the global economic and energy network. In these cases, the systems achieve steady states in which their heat dissipation is such that it maximises entropy production. Recent work suggests that this principle is even broader than we have accounted for so far, being appliable even to out-of-equilibrium systems like living beings, crystals, social networks, or stars. However, the way in which entropy is used as a prediction tool has stayed more or less the same: entropy production is maximized under given restraints. ![]() Then it was even further generalized by information theory, in which entropy provides a formalism for making the best guess on a system by quantifying the amount of missing information. The concept was then broadened by the statistical version of thermodynamics – statistical mechanics – in which entropy represents the direction in which things are likeliest to occur. This led to the formulation of the second law of thermodynamics which, ultimately, gives a sense of direction in which macroscopic processes occur. Thermodynamics introduced the concept of entropy as a way to quantify how much energy in a system could be transformed into work. ![]()
