In human thermodynamics, entropy law is a entropology-like synonym for the second law of thermodynamics. The term was introduced significantly by Romanian mathematical economist Nicholas Georgescu-Roegen in a 1970 pamphlet in which he discussed what he called the “important role of the entropy law for the existence of our species”. [1]

In this pamphlet, he argued, using a non-logical interpretation of the material entropy conception, that “the entropy law is the root of economic scarcity: it states that the natural resources on which our existence depends are continuously and irrevocably turned into waste.” This publication was followed up by his 1971 book The Entropy Law and the Economic Process, which worked to stimulate the use of the term “entropy law” in the decades to follow, especially in economics and economic thermodynamics, such as in the publications of Jeremy Rifkin, Jing Chen, and others. [3]

Etymology
Georgescu-Roegen’s use of the shorthand term “entropy law”, stems from English astronomer Arthur Eddington, whom he references in the first paragraph of his 1971 book, that in 1928 stated the famous quote: "the law that entropy always increases—the second law of thermodynamics—holds, I think, the supreme position among the laws of Nature.” [4]
