You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary. You can set it anywhere you want. It's the same with enthalpy.
你知道,如果你想测量重力场,中某种东西的势能,你需要,在某处定义一个零点,对吧?,因为势能的值是任意的,你可以把它设定在。
But if you say, well, I don't know how to do this, I am not going to bother, don't grade the paper.

If you want to get some input from the user, my God I don't want to have to program it to low level zero and 1 just to get keys from the keyboard; please let there have been someone who does that for me and indeed there are an increasingly sophisticated options that you can pull off the shelf.
如果你想获得一些用户的输入数据,我的上帝,我可不希望在键盘上敲入0,1的低水平方式来编程;,希望有个人能帮我做这件事吧,但是现有的选择,也变得日益复杂了。
Second thing we've got to worry about is, what's a basic step? All right, if I bury a whole lot of computation inside of something, I can say, wow, this program, you know, runs in one step. Unfortunately, that one step calls the Oracle at Delphi and gets an answer back. Maybe not quite what you want.

我们怎么解呢,我的意思是我现在不会去计算,因为我可能会算错,但是如果你真的很想解出X和Y的值,介于这是一节需要快速反应的课,那我们花些时间来探讨一下吧
