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

你要学习动力学，统计学，静力学。

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.

长体积类似 从张力压力改长音。

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，改比赛一些基本要素，然后再观察新均衡，这就是所谓比较静态。
