从“相互作用”看世界的“有序性”
问题：为什么“有序性”更多出现在低能量系统而不是高能量系统？
例子：冰晶比水蒸气更有序，但没有水蒸气对称性强。
此处尝试用粒子间的相互作用来回答这个问题，当然也可以从熵的角度来回答此问题。
在低能量系统里，粒子间的相互作用很强，简单和单一。
在高能量系统里，粒子间的作用很弱，复杂和多元化。
因此，低能量系统显得统一和有序，而高能量系统则混乱，无序和活跃。
低能量系统面对外界的攻击会显得脆弱，相反，高能量系统则能抵御外界的干扰。
因此，使用对称性能更准确地描述一个系统。
同样的法则可以应用到人类社会。
生产力底下的社会，人与人之间的相互约束很大，简单和单一：只要控制和被控制的关系。
生产力发达的社会，人与人之间的相互影响很小，复杂和多元化。

Interaction and order
Question: Why order appears in low energy system rather than high energy system?
Example: An ice is more order than a water vapor, but less symmetric.
I try to answered this question from the aspect of interactions between particles. What’s more, the question can be tackled from
the point of view of entropy.
In a low energy system, the interactions between particles are strong, simple and single.
In a high energy system, the interactions between particles are weak, complex, and diverse.
In this case, low energy system appears to be uniform and then “ordered”.
However, high energy system appears to be chaotic and less ordered but dynamic.
A low energy system is vulnerable to outside attacks. While a high energy system can persist the impacts from the surroundings.
For this reason, the usage of symmetric is more proper to describe a system.
Similar rules about order and interaction apply to the construction of human society.
Think about which system are you living in?
