Title:Researchers in an Entropy Wonderland: A Review of the Entropy Concept

Authors:Marko Popovic
View PDF
Abstract:Entropy concept was introduced by Clausius 160 years ago, and has been continually enriched, developed and interpreted by the researchers in many different scientific disciplines ever since. Thermodynamics and other scientific disciplines face several simple but crucial questions concerning the entropy concept. Thus, it is frequently possible to notice a misuse of entropy. Sometimes unbelievable confusion in the literature is summarized by von Neumann's sentence: "No one knows what entropy really is." Four major questions stand before thermodynamics. (1) How many kinds of entropy are there? (2) What is the physical meaning of entropy? (3) Is entropy a subjective or an objective property? (4) Is entropy in any way related to information? This paper attempts to describe the roots, the conceptual history of this important concept and to describe the path of its development and application in different scientific disciplines. Through this we attempt to give some possible answers to the questions mentioned above.
