Problem Set One will be posted on the course's website tonight by 7:00 p.m. It will very clearly walk you through the week's challenges.

I'm averaging it over the entire set of valence electrons which gives me 1.91 MJ per mole.
我是在整个价电子的集合上作平均,最后得到1。91兆焦每摩尔。

I'm going to set aside theology as the lens through which I read.
似乎很矛盾。
-
p2 I'm going to set that equal to p2.
现在外界压强为。

Part of the reason why I'm endorsing this market stability regulator is that there's no way we can set up a system that is both very effective in allocating resources and that is also very stable.
我赞成市场稳定性监控者,的部分原因是,没有方法建立一个,既能完全有效配置资源有非常稳定,的系统。
-
So basically what I'm going to do here is I'm going to set my price to equal his price, minus a little bit, I'll just undercut him a little bit and by just undercutting him a little bit, I'm going to get the whole of the market and I'll make as much money as I can on those sales.
所以基本上我要做的是,设定我的价格等于他的价格,减去一点点,我的价格将仅仅比他的低一点点,并且通过比他的价格低一点点,我将占领整个市场,那些销售带给我尽可能多的钱

I don't have a very set place because I'm so open to all sorts of different places.

Starting at the beginning of the third week of class that is not next week but the week after on each Monday I'm going to put up a brief question or set of questions, which you have to answer and your answers need to be sent to your teaching fellow.
本课程将于开学后三周开课,也就是自下下周开始,每周一上课,我会提出一系列问题,要同学们思考并回答,大家的答案要在周五前交给研究生助教

Yeah, I'm a freshman, so it's, I'm not quite set on it,
是，我大一。所以，我也没有确定，
-
I'm going to set it, do it the right way.
我会安定下来，然后按正确的方法行事。
-
This should all sound incredibly familiar, like I'm just repeating myself in terms of photoelectric effect, because essentially that's what I'm doing, and that's one reason we spent so much time and did so many problem-set problems on the photoelectric effect.
这应该听起来极其熟悉，就像我在重复自己在讲光电效应时所说的话，因为基本上我正是在这样做，这也是我们在光电效应这个问题上,花这么多时间,做这么多习题的原因之一。
-
I'm going to tell you a little bit about how they are set up and what they are.
我会介绍一下课程安排,和内容。
-
So I'm going to ask you to look now at this set of things, which is solve 1 and Barnyard 1.
所以我想问问,现在你怎样看待一些列事情。
-
I'm going to give you the data set of the scattering angles of the atoms.
我会把,这些原子散射角的数据发给你。
-
The third thing I'm going to do, is I need to set up the right end test.
我要做的第三件事情，就是需要设置正确的完结测试。
-
So I differentiated this object, this is my first derivative and I set it equal to 0 Now in a second I'm going to work with that, but I want to make sure i'm going to find a maximum and not a minimum, so how do I make sure I'm finding a maximum and not a minimum?
这样我就对它求出导数了,这是一阶导数,令它等于0,一会我们就要计算了,但我先确定一下是最大值还是最小值,我怎么确定是最大值还是最小值呢
-
Why? Because that block identifies a set of things that I'm going to do if the test is true.
为什么呢？这是因为这一块指令,指定了一系列的要进行的操作,如果测试为真的话。
-
At my maximum, I'll put a hat over it to indicate this is the argmax; at my maximum I'm going to set this thing equal to 0.
给每个最大值都标注上一个帽来,在最大值处导数方程等于0
-
And what I'm going to be doing, what I'm going to be arguing in this class, is that that set of views is pretty much mistaken from beginning to end.
我准备做什么，我准备在这里和你们辩论，那个观点从一开始到结束都是相当错误的。
-
All right? And I'm going to say-- sort of set that stage here, so that-- It turns out that that's probably about the best we can do, or again ends at the length of the list.
我要说的是，这一阶段的集合,我们用最优的方法完成,还是取决于列表的长度，好的，还是回到了我的问题上了。
-
ReadFloat We'll look at it in a second. Let me sort of set the stage up for this -- suppose I want to input -- I'm sorry I want you as a user to input a floating point number.
名字叫,我们来看一会，我先来设置下情景-,假设我想输入，抱歉,我希望你们作为用户来输入一个浮点数。
-
Right.? I'm going to set up a variable to say, none what's the answer I want to return, is it there or not. Initially it's got that funny value none.
看我要找的答案在不在数组里面，初始化为,然后建立一个索引。
-
And when I do this test, what I want to do, is say I'm going to pick the middle spot, and depending on the test, if I know it's in the upper half, I'm going to set my start at the mid point and the end stays the same, if it's in the front half I'm going to keep the front the same and I'm going to change the endpoint.
如果我知道目标数可能，再比中值点大的区间里，我可能就会把开始点设为中值点,而尾点不变，如果在小的那个区间里,就保持开始点不变而把尾点设为中值点，你们可以看到这儿的代码,就是这么做的,对不对？它是怎么做的？
-
I'm going to start with those and then I'll turn, eventually, to another set of possible things that might need explaining, which we might think of as extraordinary, supernatural things.
我将从这里开始,然后转而讨论,另一些,需要给予解释的现象,那些我们可能视之为异乎寻常的,超自然现象
-
But here, if I decide I'm going to store things not in x and y, but with some other set of names, for example, I've gotta go back into these pieces of code that use the points, and change them. So I've lost modularity.
除了要改下借口,但是这里，如果我决定，我不把值放在x和y中，而是和其他一些变量名进行绑定,例如这样的话,我就得回到使用这个点的代码，那儿去做更改了。
-
So I'm going to go over here, and I'm going to type test search-- I can type and if you look at your handout, it's just a sequence of tests that I'm going to do OK. So initially, I'm going to set up the list to be the first million integers.
大家可以看看你们的课堂材料，那儿有一些我要做的实验,好，一开始我先去建立个，含有一百万个integer的数组,对，这有点儿简单,但是这给我提供了这样一个有序的数组。
