So if you think about the way something like, say, Mapquest works, and last week in recitation you looked at the fact that shortest path is exponential.

所以如果你想想电子地图，还有上周学的列举法,你就会发现一般最简单的方法,都是指数递增的。

I could have that path be very slow and steady, so that at every point along the way, my gas is an equilibrium.

我可以很慢，很稳定地经过这条路径，因此在这条路径上的任意一点，气体都处于平衡态。

End up where you started. It's not quite the same as the shortest path, and figure out the way to do that that involves spending the least money. Or the least time, or something else.

最后回到最初的地方,这和最短路径问题有些不同,需要找出一条花费最少,或者费时最少或者满足其它条件的路径。

Think of Star festival as a textbook that is come to life and environment where students can observe and draw their own conclusions, there is a path way to a new type of learning that is independent yet guided.

将Star，festival看作是一本教科书,走进我们的生活和环境,在那，学生们能观察,并得出自己的结论，有一条路通往学习的新形式,它独立自主，但也有所指导。

Now, I wanted to go to through this just to go through one cycle quickly because we're going to be doing these all the time, and the importance of the fact that the path doesn't matter, and you can always connect things together in a way, whatever you want.

我使用这种,利用热力学循环的推导方法的原因在于,今后我们，将经常使用类似的方法,大家要记住路径是无关紧要的，可以随意选取一条路径,来连接两个态。

If it isn't, then I'm going to go back around the loop, and notice what happens. If I get all the way around the loop, that is, all the way through that FOR loop and I never find a path that takes me through here, then the last thing I'm going to do is return a pair or a tuple with a special simple number none twice.

如果没有,我会回到循环看看发生了什么,如果我运行了整个循环,也就是整个for循环,我仍没有找到符合条件的路径,那么我最后做的事情就是返回一对,或者一个数组的两次none值。
