快乐不对称定律我们可能永远也不会适应有些糟糕的情形。
The Law of Hedonic AsymmetryThere are certain awful circumstances to which we can never become accustomed.
物理定律也可以是对称的。
这样就导致了粒子物理学家们认为物理学的定律是不对称的。
This has led particle physicists to suggest that the laws of physics are lopsided.
（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。
What Noether discovered is that whenever nature displays a continuous symmetry, a conservation law comes along for the ride, and vice versa.
定律也不会因为你观察的方向不同而改变(这是转动对称性，Rotational Symmetry)。
Nor do the laws of nature change depending on the direction in which you look (rotational symmetry).
进一步的理论分析表明，只有存在一个幺正变换对称群时，才有一个守恒定律。
Further theoretical analysis indicates that there is a conversation law only when unitary transformation symmetry group exist.
这一定律的内容是：结局的形态是与开端的形态对称的。
This law says that the shape of the ending is symmetrical to the shape of the beginning.
还有一个更重要的事情，这些对称性暗示着大量的守恒定律。
An even more important fact is that these symmetries implicate a large number of conservation laws at the particle level.
从对称性原理出发，证明了能量守恒定律，并对时间平移对称性与能量守恒作了简单的几何表述。
From the principle of symmetry, law of conservation of energy is proved. And have a simple geometric express for time translation symmetry and conservation of energy.
利用简单对称性的电磁场，讨论了场和电荷系统遵从的动量守恒、量矩守恒定律。
With a simple symmetrical electromagnetic field, the law of conservation of momentum and the law of conservation of angular momentum for electromagnetic field and charges system are investigated.
由热力学第一定律及无损条件导出了介电张量的对称性；
The symmetry of the permittivity tensor is found to be based on the first law of thermodynamics and the non-wastage condition.
