Also known as thermodynamic entropy
热力学概念
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.

熵(shāng)(英語:entropy),是一種測量在動力學方面不能做功的能量總數,也就是當總體的熵增加,其做功能力也下降,熵的量度正是能量退化的指標。熵亦被用於計算一個系統中的失序現象,也就是計算該系統混亂的程度。熵是一个描述系统状态的函数,但是经常用熵的参考值和变化量进行分析比较,它在控制论、概率论、数论、天体物理、生命科学等领域都有重要应用,在不同的学科中也有引申出的更为具体的定义,是各领域十分重要的参量。
