the saying goes. But the debate over net neutrality could define how free the exchange of information is going to be in the future.

And it's always going to come down to calculating the appropriate free energy, and how it changes in the process.

这总是涉及到计算,适当的自由能，以及这些自由能在过程中如何变化。

But there are a lot of festivals and like, free activities that are going on.

这里经常有一些节日庆典和各种免费活动。

And we're going to hear a lot more later on, next week, week after, about free labor ideology.

以后我们还会涉及到更多,下周和下下周,关于自由劳动意识体系

And knowing now how to calculate these free energies especially the Helmholtz and the Gibbs free energies,that's what's going to guide us in really calculating quantitatively, OK, where will equilibrium lie.

知道如何计算,这些自由能,尤其是亥姆赫兹和吉布斯自由能之后,这些数值计算就能告诉我们，平衡态到底是什么样子。

And the Lord God commanded the man saying, 'Of every tree of the garden you are free to eat.'" His first thought is what are you going to eat?

上帝命令人们道，“你可以随意吃花园里的树木‘,他最先考虑的就是人要吃什么东西？

But there's another way to do this and I'm going to give you now the simplest example of the other way, which is to draw free-body diagrams.

不过还有另外一种方法,现在我来给你们演示,另外一种方法最简单的例子,也就是隔离法的受力分析

But we see if we have a free electron, as we do in this dotted line here, that's going to be a higher energy that's less stable.

但是我们看到如果,我们有一个自由电子，就像虚线所示那样，那将会是一个较高的,不够稳定的能量。

So again with the Gibbs free energy, now I see how to determine, if I change the pressure, if I change the temperature by some modest amount, how much is the Gibbs free energy going to change?

再一次通过吉布斯自由能，我知道当我，适当的改变压强和，温度的时候，吉布斯自由能如何变化？

So, if, for example, we were looking at a hydrogen atom in the case where we have the n equals 1 state, so the electron is in that ground state, the ionization energy, it makes sense, is going to be the difference between the ground state and the energy it takes to be a free electron.

电离氢原子所需要的能量,如果我们看n等于1的情况,电子在基态，那电离能，很合理的就是基态,和自由电子态的能量差。
