And in this case we're going to look at silicone, and we'll say if you can point out to me which requires the least amount of energy.
这次我们要做的是关于硅的，我们来看看大家是不是,能够为我指出那一项需要消耗的能量最少。

And the last thing we do for any of our structures to check them and figure out are these valid or not valid, are these good Lewis structures is to check the formal charge.
而为了检验任何一个结构是否有效,看它们是不是好的路易斯结构,我们要做的最后一件事就是检查形式电荷。

So one of the things we're trying to do here is to facilitate dinners for the students at large, undergraduates and graduate students.
所以我们要做的其中一件事是,为大部分学生提供晚餐，包括本科生和研究生。

A group of people starts a business and they say, let's divide up the proceeds.
一群人想要做一笔生意,他们说,我们把钱分了吧

I'm not sure how many of us would decide the last thing we wanted to do with our remaining years is to spend it in college.

But I want to begin today with another passage, from the war years, and ask now from a Northern point of view, how do we get to Uriah Parmelee?
但是今天我要以另外一篇文章做开始,自开战那年,从北方角度来看,我们要如何理解乌利亚·帕米利
-
Second thing they're going to do is let us suppress detail. And in essence what that does is, the functions, and we're going to look at a bunch of examples in a second, these functions are going to give us a way to, in some or in one way of thinking about it is to create new primitives.
第二件要做的事,是忽略细节,函数的本质到底是什么,我们将在接下来的几分钟，举一些例子，这些函数将给我们提供,一种创建原语的思考方式。
-
Well what you do is you bomb the food and you use something called the bomb calorimeter that looks like this, and so essentially what you do is you put the food in this device that sits inside water.
我们要做的是燃烧食物,使用一种叫弹式量热器的工具,像这样,把食物放入这种仪器中,仪器会浸入水里
-
I mean, you should not imagine when I say slaves--just take out of your mind the plantations of the old South, because when you only have one or two slaves, the master is working right alongside them, doing exactly the same work that they are doing, and also instructing them and telling them what's what.
我的意思是,当我们提到奴隶的时候,大家不要想当然地联想到南部种植园,因为当你只有一两个奴隶时,奴隶主必须要和奴隶一起劳作,做着和奴隶一样的农活,并且不断告诉他们要做什么
-
And so if we wanted to do this here, it's again, the same thing we're just now pulling back this layer and calling them char *s not actually strings.
如果我们想要在这里这样做，再次，我们撤销这一层,把它们叫做char，*s，实际上不是字符串。
-
And in doing that, we'll also talk about the shapes of h atom wave functions, specifically the shapes of orbitals, and then radial probability distribution, which will make sense when we get to it.
为了这样做，我们要讲一讲，氢原子，波函数的形状，特别是轨道的形状，然后要讲到径向概率分布，当我们讲到它时，你们更能理解。
-
.. What I'm going to do now-- let's start out with the case where-- now it's going to get a little bit more complicated if we drop the independence assumption.
我现在要做的是-,让我们从案例开始-,接下来的情况会比刚才的复杂一点,因为我们去掉了“相互独立“这一前提假设。
-
What I'm going to do is basically run through my attempt to reconstruct-- my attempt to lay out the basic ideas from this series of four or five arguments that Plato gives us.
我要做的是,基本上是重新,把柏拉图给我们的这4,5个论点中,一些基本的观点拿出来讨论一遍
-
So, if you can flip your lecture notes over and just write on the blank space, we're going to cover electronegativity first here, and specifically, you can go back and fill this in to your lecture 9 notes, if you want to stay organized, but I just suggest just writing it on lecture 10 notes now and going back.
因此，请大家把讲义翻到背面,就在空白处做一下笔记，我们要先讲一讲电负性，特别提醒一下，大家可以,回到第九课的讲义并把这些记在那里，如果你想保持条理性的话,但是我建议大家先写在第十课的讲义上,回去再记到第九课的讲义上。
-
or at least one mechanism, I shouldn't say -- the only one-- one mechanism for doing that is going to be to add functions is that it's going to provide both of these things, so the first thing it's going to do is, it's going to let us break up into modules.
我们处理这些的机制--至少一种机制,我不会说只有一种,一种机制是在我们的语言中增加函数,函数的关键是它要提供分解和抽象,所以第一件要做的事，就是将代码分解为模块。
-
But within all of these groups is an attempted try to get down something that's so fundamental, and we just have to safeguard. I'm thinking broadly in terms of social justice criteria, others may say human dignity. There're certain things we do to safeguard others' human dignity.
但在所有这些群体中都有一种努力,在尝试着记录下最根本的东西，而我们要做的就是维护，我在广泛思考着,社会正义的标准，其他人可能会说是人的尊严，有些事情,我们会做从而维护他人的尊严。
-
And that shows you one other nice little thing we want to do, which is if I look in this code notice I set up a variable up here called false Solution Found, initially bound to false.
这显示了我们想要做的另一件事,那就是我在这段代码中设置了一个,名为Solution，Found的变量,初始值设为。
-
OK. We wanted to finish up that section, we're now going to start on a new section, and I want to try and do one and a half things in the remaining time. I'm going to introduce one topic that we're going to deal with fairly quickly, and then we tackle the second topic, it's going to start today, and we're going to carry on.
我们该结束这一段了，现在我们要开始新的课程，我在接下来的时间里要做1。5件事情,我首先会很快的对一个我们,要学习的课题,进行一个介绍，然后再进入第二个话题，今天我们只是开始这个话题，以后还要继续讲。
-
So we're to assume we can get to any piece of data, any instruction in constant time, and the second assumption we're going to make is that the basic primitive steps take constant time, same amount of time to compute. Again, not completely true, but it's a good model, so arithmetic operations, comparisons, things of that sort, we're all going to assume are basically in that in that particular model.
因此如果我们假设在恒定的时间内,我们可以取得任何一块数据,任何一种数据结构的话,我们要做的第二个假设就是,基本的原始操作计算花费的时间是恒定的,这个假设也不是完全正确的，但这个模型其实挺不错的，因此算法操作，比较，这一类的事情，我们在这个特定的模型中都假设是基本的,操作，花费的时间是恒定相同的。
-
And in this case, we go from 8 to 4 to 2 to 1 three times and then on each iteration of this algorithm, each pass across the board I'm touching N numbers, so that means I'm doing N things, log N times.
在这个例子中，我们从8得到4，到2，再到1，是3次,在这个算法的每次迭代中，每一趟我都会操作N个数，也就是所我每次要做N步操作，一共要做，log，N，次。
-
But actually there is a little bit of an energy cost into doubling up into a single orbital, because, of course, it takes energy when you create more electron repulsion, that's not something we want to do, but we have to do it here, and it turns out that that effect predominates over, again, the energy that we gain by increasing the atomic number by one.
但实际上，在一个轨道上放两个电子,确实会亏损一点能量，因为，当你加入更多电子，引起更大的排斥能,这显然会消耗能量，这不是我们想要做的，但是在这种情况下我们不得不做，结果这一影响，超过了增加一个,原子序数所得到的能量。

I feel pretty good here. Right?
我们想要做一份res的拷贝？
