entropy

/ˈɛn.trə.pi/

Definition

A thermodynamic property representing the state of disorder or energy distribution, often linked to the thermal energy and temperature of a system.

Etymology

Coined in 1865 by physicist Rudolf Clausius, the word combines the Greek 'en-' (in) and 'trope' (transformation or turning). It was constructed to mirror the word 'energy' while representing the tendency of energy to become less available for work.

In the news

The term is used here to reference Jacob Bekenstein's foundational theory that black holes possess entropy and a specific temperature. This concept helps scientists bridge the gap between thermodynamics, general relativity, and quantum mechanics.
