(Boltzmann definition) A measure of the disorder directly proportional to the natural logarithm of the number of microstates yielding an equivalent thermodynamic macrostate.

日本語の意味

（ボルツマンの定義に基づく）熱力学系における、系の無秩序（乱雑さ）の度合いを表す量。具体的には、同一の熱力学的マクロ状態を生み出すミクロ状態の数の自然対数に比例して決まる。

In the lecture on statistical mechanics, the professor explained that entropy quantifies the disorder and is proportional to the natural logarithm of the number of microstates corresponding to a given thermodynamic macrostate.

統計力学の講義で、教授はエントロピーが無秩序の尺度であり、ある熱力学的マクロ状態に対応する微視的状態数の自然対数に比例することを説明した。
