AI overview

Entropy is a measure of disorder, randomness, or uncertainty that appears throughout nature and science, from the behavior of heat and molecules to the organization of information. It matters because understanding entropy helps explain fundamental processes in physics, chemistry, biology, economics, and technology—essentially how systems change and evolve across virtually all scientific disciplines.

Le terme entropie a été introduit en 1865 par Rudolf Clausius à partir d'un mot grec signifiant « transformation ». Il caractérise le degré de désorganisation, ou d'imprédictibilité, du contenu en information d'un système.
