It is not personal." "We can actually see where he is here.
VOA: standard.2010.07.22
-
So we can see what it's doing is it runs. So let's try fib it here with Fib of 6.
我们可以看到它在,运行的时候做了什么,让我们试试。
-
So what we see here is an example of something very important and quite general.
因此我们现在已经看了,一个非常重要而且很普遍的问题。
-
So, just looking at putting in the electrons, filling up the energy diagram here, we should be able to see a little bit why this is happening.
那么，仅仅通过观察这些电子的位置，在能级图上如何填充，我们应该就可以看出一点端倪。
-
In the 1st part you can see is that we zoom in here to the very back of the brain.
第一部分中,大家看到的是我们放大了的大脑后面的部分。
-
So here's what we find, and as you can see there -is this bass rhythm moving slowly or quickly?
那么,大家能看到,这个低音节奏是缓慢还是迅速
-
And here we already see a hint that make is going to simplify all of that for us.
所以我们刚学习了怎样简化,操作的一个方法。
-
What we see here is a doubled voice.
在这里，陈述的声音开始分裂成。
-
So between b e, and b, between n and o, magnesium and aluminum, and then phosphorous and sulfur, what we see here is that we're kind of going down, or quite specifically, we are going down.
比如从铍到硼，从氮到氧，从镁到铝，从磷到硫，我们在这些地方看到有点下降，或者可以明确地说，我们确实在下降。
-
Well, what we can see here is that I'm computing the same value over and over again.
好吧，我们现在看到的是,我不断地在计算同一个值。
-
So what we should expect to see is one radial node, and that is what we see here 3s in the probability density plot.
个节点,这就是我们，在这概率密度图上所看到的,如果我们考虑。
-
So first thing we should do is scratch our heads and see what's going on here. Alright, let's look at it. What's happening here?
所以我们要做的第一件事,就是抓抓脑袋看看发生了什么,好了，让我们来看看，这儿发生了什么呢？
-
So, let's, for example, look at nitrogen. So n 2, we can do the chart here in green, so it's the green dotted line, and what we see is that we have now defined this energy as where the 2 nitrogen atoms are separated.
那么，让我们举个例子，看一下氮，那么氮分子，我们可以把它用绿色曲线画在这，这是绿色的虚线，可以看到,我们已经定义为零点能，当两个氮原子分离时。
-
We're going to focus now on some passages where we can do it, and we're going to see how Beethoven is setting up some chord progressions here.
我们现在准备将注意力集中到我们可以找到的那些乐章上，来看看贝多芬如何进行和弦的。
-
And what he found here, which is what you can see and we can all see pretty clearly, is the slope of all of these lines is the same regardless of what the type of metal is.
他在这发现，你们也,可以很清楚的看到，不同金属直线的,斜率是相同的。
-
So what we'll have here is a trigonal planar case, and you can see that we only have three electrons that are set for bonding, so we'll add three hydrogens, and for b h 3, we'll get a stable structure here.
让电子劲量远离的时候，不用考虑它,这个例子是平面三角形，你可以看到，只有3个电子可以成键。
-
But what we see we have is that we only have two unpaired electrons here.
但我们看到,我们只有两个未配对的电子。
-
So what we see is on ammonia here, 107 we know that it's less than a 109 . 5, it's actually 107, so it's less than a 109 . 5, because of that lone pair pushing down in the bonding electrons.
我们看到在氨分子里，我们知道它比１０９．５要小，它是，所以比109。5要小，因为孤对会把成键电子向下推。
-
So we see that the memoization here is buying me a tremendous advantage.
所以我们看到这里的默记法,给我们带来了很大的提高。
-
We start with j pointing here, and we can see what this loop's going to do, right? j is just going to move up.
我们让j指向这里，我们能看到这个，循环要做什么？,对吧，j要开始移动了。
-
We know we need to divide by 266, 266 but what we need you to help us with is to figure out this top number here and see how many particles are going to backscatter. So if the TAs can come up and quickly hand out 1 particle to everyone.
知道背散射的概率就可以了，我们知道要除以,但还需要你们来搞清楚,分子上的数是多少，有多少个发生背散射的粒子,助教们请过来,把这些球分给同学们。
-
These 2 are going to come together like this, and the first bond that we're going to form is going to be a sigma bond, right, so we see that here. If we're looking head on, we see they form a sigma bond.
它们两个会靠近到一起，首先会形成的是,一个sigma键，对吧，我们在这里可以看出来，我们看到它们形成一个sigma键。
-
What's going on underneath the hood is we'll see pictorially X today is that when I declare this X, this variable X here.
底下所做的，我们将看到,当我声明这个X，这个变量。
-
And then we'll see exactly what it is that he's doing here so we're going to try to lock in on the bass.
现在我们来听一下这首歌究竟是什么样的，然后我们来尝试专攻它的低音部分。
-
d1 2 3 And we can do that just going along, 3 d 1, 2 3, and the problem comes when we get to chromium here, which is instead of what we would expect, 4s23d4 we might expect to see 4 s 2, 3 d 4.
我们能做的就是继续，问题出现了,当我们来到铬元素时，它不是我们预期的那样，我们可能预期。
-
And similarly, actually, if we're looking at our polar coordinates here, what we see is it's any place where theta is equal to is what's going to put up on the x-y plane.
类似的，如果我们,看这里的极坐标系，我们能看到只要在theta等于,多少的地方就是ｘｙ平面。
-
So that's why we see the 2 p here, 1206 the 2 s is 12 06, and it makes sense that what we see as the greatest ionization energy, which is also the smallest kinetic energy is that 1 s orbital.
这就是为什么我们看到，2，p在这里，2，s对应,那么我们看到对应最高的电离能，同时也对应最低的动能的,应该就是，1，s，轨道。
-
And what we see here is now when we're combining the p, we have our 2 p x and our 2 p y orbitals that are lower in energy, and then our pi anti-bonding orbitals that are higher in energy.
这里我们看到,当我们结合p轨道时，在低能处我们有,2px和2py轨道，π反键轨道在更高的能级处。
-
So here we have energy increasing on the y-axis, and you see this straight line at the bottom here is lower down on the graph, and that's the energy of a bound electron, so that's going to be a low stable energy.
这里我们看到能量沿着y轴增加，而且在这张图片上,这条直线在底部是降低的，那是一个束缚电子的能量，所以那是一个低稳态能量。
-
So if we write the electron configuration you see that this is the electron configuration here, 1s22s22p 1 s 2, 2 s 2, 2 p 6, 3s1 and now we're going into that third shell 3 s 1.
现在我们来到第三层,你们会看到3s1价电子之间的区别，电子构型是，现在我们来到第三层。
