Defined as entropy, the second law of thermodynamics proposes that energy is more easily dispersed than it is concentrated. One basic illustration of entropy is to imagine white and black sand: once mixed together, it is highly unlikely that the contrasting grains of sand can be separated and restored to their original distinct color groups. Arturo’s Trópico Entrópico ( Entropic Tropics , 2012) considers the colonization of the American continent as a similarly irreversible process of cultural entropy.
