U+71B5 "熵" CJK Unified Ideograph-# Unicode Character

U+71B5 "熵" CJK Unified Ideograph-# is a Chinese character representing the concept of entropy, a term borrowed from physics to describe a measure of disorder or randomness in a system. In modern Chinese, it is frequently used in scientific contexts such as thermodynamics and information theory, where it quantifies the degree of uncertainty or chaos. The character itself is composed of the radical for fire, "火," on the left, and the phonetic component "商" on the right, reflecting its historical connection to heat-related phenomena. Beyond technical usage, "熵" has also found its way into philosophical and metaphorical discussions, often symbolizing inevitable decay or growing complexity in systems over time.
