Reversiibelit

Reversiibelit is a neologism used in discussions of reversibility to describe the degree to which a system or process can be returned to its original state after undergoing change. It is not a formally standardized term, and its precise definition varies by field; however, it generally implies minimal information loss and low energy dissipation during the reversal.

In physics and thermodynamics, reversiibelit relates to processes that approach ideal reversibility, with minimized entropy production. In computing, it connects to reversible computing, which aims to perform computations in an information-preserving way to reduce energy use, in line with Landauer's principle. In chemistry and materials science, it describes materials or reactions that can revert to their initial composition and structure when external conditions such as temperature or pressure are removed or reversed.

Because the term is not standardized, its interpretation depends on context. Critics note that the lack of a universal definition can hinder precise communication, while supporters view reversiibelit as a useful comparative label across disciplines for discussing how close a system comes to ideal reversibility. Related concepts include reversibility, reversible computing, and entropy-related losses.
