One of them,the Apollo-11, traveled to the moon just seven months after the last X-15 flight.

Remember, we don't do a one-to-one correlation, because p x and p y are some linear combination of the m plus 1 and m minus 1 orbital.
记住，我们不需要把它们一一对应，因为ｐｘ和ｐｙ轨道是,ｍ等于正负１轨道的线性组合。

Again, same kind of reasoning says, given some value x, I happened to pick a small one here, what's an easy way to do this? Well, let's just start at one. That's my variable I'm going to change and check.
好，尤其是，让我们到这里来,让我给大家看看第二个例子,让我把这个注释掉，这是我要解决的，第二个问题，假设我想找到一些整数的,所有除数，我想要找出来这个数的所有的除数。

The three X-15s were flown one hundred ninety-nine times.

At this point, we have no other choice but to double up before going to the next energy level, 2px so we'll put a second one in the 2 p x.
在这点上我们没有其他选择,而只有双倍填充,在到下一个能级之前，所以我们放入第二个电子至。
-
Okay. That's one way to read the simile, one way to make sense of this mention of the X, the Galileo figure.
这是理解这个比喻的一种方式，一种了解X，即伽利略的形象的方式。
-
We give you a very rich table of constants that's got all kinds of things from the mass of the electron to the speed of light, and all this stuff to the requisite number of significant figures. And, in addition, you are allowed to take in one sheet of paper, 8 1/2 x 11 one sheet 8 1/2 x 11, you can write anything you want on it.
我们会给你一个很详实的常量表,将会涉及很多方面，从元素的电子,到光速，这些内容到有效数字的定量,还有，你们可以带来一张纸，纸的规格是，可以写任何你们想写的东西。
-
int X Well, if you declare int X up top, you could certainly update X to one here.
嗯，如果你在顶端声明，你可能把X更新为1了。
-
Then, I gave you one other very important example of a particle moving in the x-y plane.
下面我再拿一个重要的例子,质点在 x-y 平面内的运动
-
If you wrote only one policy, what's the probability distribution of x/n?
如果你只签了一份保单,那么x/n的概率分布是怎样的?
-
Take these two equations, put an equal sign between them, replace this PR throughout with X, I'm going to have one equation and one unknown and that even the math phobics in the audience did in high school.
在这两个方程中间加个等号,将这里的Pr换成X,就会得到一个等式和一个未知数,剩下的问题,大家高中的时候就该回做了吧
-
If you look at x 2 this one right here in your handout. OK.
课堂材料的第二题2,这是关于做乘方的另外一种方法。
-
py So you can either write 2 p x or 2 p y, whichever one you want is fine.
这是对的，你们可以把它写成2px或者，哪种都可以。
-
You can see that we have two unpaired electrons in this molecule here one in the pi 2 p x star, and one in the pi 2 p y star orbital.
你们可以看到我们这个,分子力有两个未配对电子,一个在π2px星，一个在π2py星轨道。
-
And by state we just mean orbital, so if we're looking at the p orbitals here, x that means that a single electron goes in x, and then it will go in the z orbital before a second one goes in the x orbital.
我们说的态仅仅意味着轨道，所以如果我们观察这里的p轨道，那意味着单个电子进入，然后它会进入z轨道,在它第二个进入x之前。
-
X I'm passing an X, and yet I'm also assigning the return value to X. So just intuitively what's going to be the effect of this one line of code?
我传一个X，之后我把返回值赋值给,很明显，这一行代码,将会产生什么作用？
-
And so I went through the math on this and said suppose I wanted to be really sloppy and I wanted to say if the delta X, the uncertainty in position is on the order of one angstrom.
我算完它,并说假如我想很草率,并且我想说如果x的增量，即位置的不确定度,相当于一埃。
-
And keep going, until the square of one of those integers is greater than or equal to - sorry, just greater than x. OK, why am I doing that? When I get greater than x, I've gone past the place where I want to be.
如果还是比x小的话，跳到3，这么继续下去,直到一个整数的平方大于或者等于,对不起，是大于x，好,为什么我要这么做呢？,让我得到的整数的平方和。
-
So i and j are vectors of length one, pointing along x and y.
和 j 是模长为1的矢量,分别指向 x 轴和 y 轴方向
-
If you plug in x equals one that is our series.
如果你定义x等于1这就得到了我们的式子。
-
Once I've got that, you notice I can now define a polar point, same way. Notice I've now solved one of my problems, which is, in each one of these cases here, I'm creating both x y and radius angle values inside of there.
你们注意到我现在可以，定义一个极坐标点了，以同样的方式,请注意到现在，我已经解决了我的问题之一了，也就是，在这些例子中的每一个,我在里面都创建了x，y值。
-
X This is H. We've got one "x" here.
这是H，我们得到了一个。
-
We said, "Let's take, for the simplest case that we can possibly imagine, namely a particle moving in one dimension along the x-axis with a constant acceleration a.
我们说过,"考虑我们可以想象的最简单的情况,即质点在一维空间运动,沿着 x 轴且保持恒定加速度 a
-
And that's the following. Let's take a particle that is moving in the x-y plane, so that at one instance-- sorry, let me change this graph-- is here--oh, this is bad.
接下来,我们来看一个物体,在 x-y 平面内运动,在这个例子中,对不起,我要重画一下这个图,在这里,这画得不好
-
OK? And in fact, if you look at the code up here, and it's on your handout, the very first one, x 1, right here- if I could ask you to look at it-- is a piece of code to do it. And I'm less interested in the code than how we're going to analyze it, but let's look at it for a second.
实际上，如果你看看,你们课堂发的材料上面的代码，第一页上的，就是那-,大家请看看实现的这一部分代码,我不太关心,我们会怎么解释这个代码,首先让我们先看看。
-
And I think in the polar one I said, if, what did I do there, I said, yeah, again if the x and y are greater than the other one, I'm going to return them to it.
然后我要返回一些值，我认为在极坐标的形式下我说过，如果，我在这里做了什么来着,我说过，对，再说一次，如果x和y坐标。
-
And when you call a function, one of the things X that happens is whatever your passing in, for instance, X, ; and if this is A, this thing gets copied into A; so at that moment in time of calling increment, I actually have two copies of the same value in memory but they're referred to by different names.
当你调用一个函数，其中发生的一件事情是,不管你输入什么，比如，或者是A，它把这个东西复制到A中;,调用increment的时候，实际上在内存中，有两个同样的值的内存块,但是它们有不同的名字。
-
So what we're going to do is take the equations for those two lines, so here's one of those equations and here's the other one, set the P in those equations equal to X, I've got two equations in one unknown, I'm sorry, I've got one equation and one unknown.
接下来我们只需要,列出这两条线各自的方程,也就是这个方程和这个方程,把方程中的P换成X,我就得到了两个等式和一个未知数,错了,是一个等式和一个未知数
-
And now we get the p orbitals, remember we want to fill up 1 orbital at a time before we double up, so we'll put one in the 2 p x, then one in the 2 p z, and then one in the 2 p y.
我们到了p轨道，记住在双倍填充之前,我们想要每次填充至一个轨道，所以我们在2px填充一个然后2pz填充一个，然后2py填充一个。
-
And actually, if I don't want to clobber, as we say, overwrite the value of my variable, ; I could declare another one and store the return value in Y; Y so now I have two ints in memory; X and Y, 3 one with two, one with three.
实际上，如果你不想彻底清除，像我们说的，覆盖那个变量的值，我可以申明另一个变量Y，并在Y中保存那个返回值;,现在内存中有两个int数，X和，一个的值为2，一个为。
