So let's take a look down here at what I'm doing and notice here that this is perhaps more compelling; right?
让我们往下看一下我在做什么,请注意这里这个可能是更引人入胜的,对不?
How many steps does it take for this function to run? Well, you can kind of look at it, right?
这个方法运行了多少补?,你可以看看代码?
All right. Let's take 10 more seconds on that, this should be a quick identification for us to do.
好,给你们10秒钟,这对你们来说应该很快就能答上来了。
So, I take that that's all right with you-- that you can come to a special section of this class.
我假设对你们来说,时间不冲突,你们可以把这当做特殊课时
We take this Cv and put in the exponent here R right. And we put this R up in the exponent here.
我们把这个Cv提出来,放在这里的指数上,好吧?然后把。
All right, what we gonna do, we want to take a derivative of this thing.
接下来我们要求导了
Now what I want to do is take you exactly to this place where we are right now, where we see energy levels and electron filling, but I want to start all over again and I want to use a totally different approach.
现在我想做的是带你们,到达我们现在所处的地方,我们能看到能量级和电子分布的地方,但我想重新开始,而且用一个完全不同的方法。
It is structured and ordered into a few basic regime types. In this I take it to be one of the most important propositions and ? insights of political science. Right? So far?
它是经建构与安排成,数种基本的政体类型,这个在我看来,是其中一个最重要的政治科学主张与见解,还好吗,到目前为止还懂吗?
One is, he can't afford to have his hoplite line outflanked, because if I can come around and take care of this guy from this side, he is engaged with a guy who's right opposite him, I can just kill him no problem at all.
一点是,他不能让方阵的侧翼被包围,因为如果我调转方向,从这边对付他,他正在和正面的敌人交战,我干掉他就是小菜一碟儿
Well, unfortunately, we know this is not the right answer, because if you take the first derivative, I get 2t.
遗憾的是,我们知道这还不是正确答案,因为如果对它求一阶导数,会得到2t
We take this other hemisphere,the right half of my brain and we stick it into Smith's torso.
将另一半脑子,右半脑,放入Smith的躯体。
It says, take this thing on the left and use it as a name to bind to the value on the right.
它意味着,把左边的对象,当做名字绑定到,右边的值上去。
Right, so the things we want you to take away from this are, get into the habit of using pseudo code when you sit down to start a problem, write out what are the steps.
好,这儿我想大家明白的就是,养成解决问题时先写伪代码的好习惯,把步骤都写出来,我想要告诉你们的是一个好的程序员。
So that's good. Don't take it, right. Sorry. This is the don't take branch.
所以正好,不能装,对,抱歉,这边是不装物品的分支。
All right. Let's take 10 more seconds on this.
好,给你们10秒钟。
I think the easiest way to look at what this does, is let's take a really simple example- I want to make sure I put the right things out- I've got a simple little list of values there.
到底做了什么,就是让它跑一个简单的例子,我想要确信我找到了正确的元素-,这里我用一个简单的小的列表-,如果我去代码里面看。
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?
I hope Washington doesn't take this long to fix my 401k plan. All right?
我希望华盛顿不会花这么长的时间,来修正我的401k计划,对不对?
