You're gonna have to study dynamics, statistics, statics.

你要习动力，统计，静力。

These changes in length and volume work in a very similar way to the changes in length and volume from stress and strain, that we talked about in our episode on statics.

体积的变化类似 从张力压力改变声音。

We looked at a game, we found an equilibrium, we changed something fundamental about the game, and we looked again to look at the new equilibrium, that's called comparative statics.

我们观察一场比赛， 找到一种均衡，改变比赛的一些基本要素，然后再观察新的均衡，这就是所谓的比较静态。
