All right. So let's think about how to draw the oh, actually, let me let you tell me how we should start this Lewis structure.
好,那么我们来想一想应该怎么画,噢,实际上,我想让大家来告诉我,我们应该怎么开始画这个路易斯结构。
The Elder Brother is issuing this theory without any consideration, - obviously, whatsoever of earthly reality and we're shocked by -- I don't know how else to put it.
大哥没有经过任何思考就提出了这个理论,显然,尘世间的任何事实都让我们震惊了-,我不知道怎么去说。
And yeah, I know you know how to do it, but let's think about what might happen if I wanted to do that.
对,我知道你们知道该怎么做,那么让我们看看如果我,想要完成的话会发生什么。
What I was saying is after you gave your own name, put brackets and then the nickname by which you want me to refer to you.

I want you to see how science is conducted.

So I don't know how people feel about taking-- maybe I'm turning you off by saying this-- There's going to be a lot of detail in this course.
我不知道你们是怎么想的,也许说这个让你们很倒胃口,本门课中也有很多细节内容
I know that may seem like a surprising thing to say when I've just sort of gone on my little gleeful amount about how I'm going to fail all of you, but it's worth my saying you guys are so smart.
我知道这说起来很奇怪,当我有些幸灾乐祸的说,关于我怎么让你们全部不合格,但是这值得我说你们聪明非常。
Well we could begin with George Washington Alright, for your sake, we toss in John Kennedy ... who cut taxes. -Because... the Kennedy tax cuts and the Reagan tax cuts ... were both major tax cuts. -Did you hear me ask him ? for a one-word answer? Did you hear me?
那干脆从乔治·华盛顿谈起得了,真是的,好吧,看在你的面子上,姑且把他算上吧,他好歹也减税了,-因为。,肯尼迪的减税和里根的,都不可等闲视之,-我不是让他,只回答一个字吗?他怎么说这么多?
All right. So it's fun, and I got a little bit of applause out of it, which is always nice for me, but I also showed you how to think about it recursively.
好,挺有趣的,我也得到了一点掌声,这让我挺高兴的,但是我想让大家明白,怎么用迭代的思想来解决这个问题。
Again, you have to let me back up slightly and set the stage.
怎么去写代码,让我准备准备。
Because,indeed,they don't exist They're merely possible And we might say,you've got to exist in order for something to be bad for you But once we say that it seems we're running towards the position that in that case,death can't be bad for me because of course,when I'm dead,I don't exist ? So how can anything be bad for me?
因为他们其实并不存在,他们只是一种可能,我们由此认为你必须首先存在,某事才会让你害怕,但我们一旦这么说,我们似乎会得出这个结论,这种情况下死亡不可能让我害怕,因为我死了就不存在了,所以我怎么会害怕?
Actually for that, I can just use, if I'm lucky, function F5, which didn't work, so let me try it again,here we go.
实际上这一次,我是想用用,如果我够幸运的话,用下F5,噢,怎么不灵,让我再试试,好了。
OK, so how can I code this up? Well, you might think, let's just jump in and write some code, I don't want to quite do that though, because I want to show you another tool that's valuable for thinking about how to structure the code, and that is a something called a flow chart. Now.
好,那么我怎么把这个以代码实现呢,你可能会想,让我们进去直接写代码把,但是我不想这么做,因为我想教给大家另外一项很有价值的,用来组织代码的工具,叫做流程图,现在,像Guttag教授,和我这么大岁数的人。
