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.
（德国数学家） Noether 所发现的是，只要在自然界呈现连续对称性（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.
这节课就到这里,下节课将由Bob，Field讲授,我们将学习功与热量的关系，认识到它们在本质上的相同之处，并通过热力学第一定律，亦即能量守恒定律，把它们联系起来。
