The English word 'entropy' is primarily a scientific term from thermodynamics and information theory. In everyday English, it is sometimes used metaphorically to mean disorder or chaos. This guide focuses on how to express these concepts naturally in Japanese, from technical to casual contexts.

In information theory contexts, 'エントロピー' alone is often understood, but '情報エントロピー' is clearer.
