Anne Lindbergh found that one answer to this problem was to be alone.

And this one will be particularly germane to a portion of Problem Set 1, at least in Problem Set 1.
这个程序跟习题集1中的,一部分比较相似,至少在习题1中。
We'll talk more about this later, but it often happens that when you change your program to solve one problem you break it, and things that used to work don't work.
我们以后会更多的去讨论者一点,但是经常发生的情况是当你因为,一个问题修改你的程序的时候,你修改了程序,但原来没问题的模块。
You can think of it as this reaction to the problem of lateness that accounts for one of the invocation's most distinctive features, and that's the repetition of the word "first."
你们可以把弥尔顿在这首诗中对“晚“的回应,当做这首诗最明显的特征之一,这表现在他反复使用“初/先“一词上“
So that way you can have an idea if, oh, I do really understand this but I'm a little bit slow, maybe I need to practice this one type of problem a little bit longer so I can get up to speed so I'm going to be able to get through all this in terms of the exam time.
这样你就可以知道,假设,噢,我真的懂这个,但是我的速度有点慢,或许我需要在练习这个类型的题目上,多花一点时间,这样我就可以提高自己的速度,可以全部做完,在考试规定的时间内。
But one problem that this also caused is if you're going to put all the books, the documents that you think are scripture,between two covers with the scrolls,you can take one out and put another in.
但这引起了一个问题,如果你要为,那些被认为是圣典的书籍加上封面,如果是卷轴你可以随意取舍。
So, we are now going to do one standard problem where we will convince ourselves we can apply this formulas and predict the future given the present.
我们接下来将去研究一个标准问题,通过这个问题,我们能让自己相信,我们能利用这些式子,根据现状,预测未来
This one's going to be on the problem set.
这个条件的分析是第一个习题集的内容
One other very important thing to understand about this defensive problem and this is one of the debatable issues between the old guard and the traditional interpretation; I'm still giving you the traditional view.
对于防御的问题还有另外一个很重要的因素,这也是老顽固们对传统观点,争论的一个话题,我还是采用传统观点的说法
I wanted to say one more thing because I realize that you have to-- your first problem set will cover this-- is to talk about the concept that applies probability theory to Economics.
我还想提一点,因为我意识到...,你们的练习题中会涉及到这个,概率论在经济学中的,应用的问题
Well, realize one of the themes in this course and really one of the themes in programming and solving any problem with a machine is going to be really to just take small bites one at a time out of these problems until the end result ultimately is that you've actually bitten off a fairly large fairly interesting problem and in the aggregate, you've actually implemented something pretty sophisticated.
好吧,让我们先想一下这件事带给我们的主题,编程和解决问题的思想,一台机器最开始只会一步一个脚印,沿着要解决的问题向前迈进,直到最终的结果出来,最后你会发现,你已经解决了一个相当大,相当有趣的问题,而这个问题在最初看起来确是相当复杂的。
In the famous battle of Marathon, which I will tell you about when we get there, one of its features is that because the Greeks were numerically badly inferior to the Persians, they had this problem of covering the line.
比如在著名的马拉松战役,迟些我们会讲到,马拉松战役中,希腊军队,在人数上远不敌波斯军队,这为布阵造成很大的困难
So, just, if you can take what I'm saying for a moment right now that in fact this should collapse in this very small time frame, we have to see that there's a problem with one of these two things, either the Coulomb force law or Newtonian mechanics. So, what do you guys think is probably the issue here?
所以如果你们考虑我,开始说的这个塌缩应该,发生在很短的时间里,那么这两者之一就有问题,要么是库伦定律,要么是牛顿力学,你们觉得应该是哪个的问题?
Those nine hours are going to be primarily working on problem sets, and all the problems sets are going to involve programming in Python, which is the language we're going to be using this term Now, one of the things you're going to see is the first problem sets are pretty easy.
这九个小时会是问题,提出的基本锻炼,所有的问题提出,都将涵盖,我们这学期,将使用的Python语言的程序,现在,你们将要看见的,第一个问题的提出非常简单。
So this is kind of a modern show and that is kind of a retro language and it's also as will be one of the takeaways of this course completely irrelevant to what problem you are solving, the fact that this engineer is using--proclaiming to use Visual Basic really is not a compelling part of the story.
这看起来很时髦,像是重新流行的语言,当然,该语言是我们学习这门课程,过程中附带着要学习的,这与解决什么问题无关,事实上,使用VB真的不是,这个故事出彩的地方。
