conservation law

基本解释

What Noether discovered is that whenever nature displays a continuous symmetry, a conservation law comes along for the ride, and vice versa.
（德國數學家） Noether 所發現的是，衹要在自然界呈現連續對稱性（的地方），守恒定律就一定成立，反之亦然。

All right, now what we're going to learn next time and Bob Field is going to teach the lecture next time, is how heat and work are related, and how they're really the same thing, and how they're related through the first law, through energy conservation.
這節課就到這裡,下節課將由Bob，Field講授,我們將學習功與熱量的關系，認識到它們在本質上的相同之処，竝通過熱力學第一定律，亦即能量守恒定律，把它們聯系起來。
