"We'll address directly the notion, I think,that many have wondered, which is the juxtaposition of the timing for the Nobel Peace Prize and his commitment to add more troops into Afghanistan,"

So any time that you're drawing these molecular orbital diagrams you want to keep in mind that the number of electrons that you have in atomic orbitals, you need to add those together and put that many electrons into your molecule.
任何时候当你们画分子轨道图时,你们要记住,原子轨道里的电子数,你要把它们加在一起,并放到分子轨道里去。
The one problem that we run into is as we go to more and more atoms on the table, as we add on electrons, the Schrodinger equation is going to get more complicated.
我们将会遇到的一个问题,是当我们处理周期表中越来越多的原子时,当我们增加了电子,薛定谔方程,变得愈加复杂。
And when you start jamming sugar and fat into things, the calories add up really fast.

Well, we'll just add those into our pantheon of gods too."
也加到我们的众神里去吧“
Is to say, okay now let's try to enrich the model, to add more into the model, and see if you get a different result, and if so why?
好吧,那我们就来完善这个模型吧,给这个模型加入新的约束条件,看看会不会得到不同的结果,如果是再分析原因
That means starting at the first one, I'm going to do something to it. And what am I'm going to do? I'm going to take that character, convert it back into an integer, and add it into some digits. And I've done a little short hand here, which is I should have said some digits is equal to some digits plus this.
这意味着从第一个字符开始,我要对他们进行一些操作,我要去做什么呢?我要取得这个字符,然后把它转换为整数,然后加到某些数上面去,我在这里用了一些缩写,我本来应该写一个数字等于这个数字。
So if we're comparing the difference between these 2 now, what you'll notice is that in nitrogen we have all half-filled 2 p orbitals, and now, once we move into oxygen, we actually have to add 1 more electron into 1 of the 2 p orbitals.
那么如果我们来比较下它们两个有什么不同,你会发现氮的,2,p,轨道,都是半满的,现在,我们继续看一下氧,我们不得不在其中一个,2,p,轨道上,再放上一个电子。
Same thing with cmp, that's just saying greater than, and greater than now can apply to strings, it can apply to floats, it could apply to points, it could add other pieces into it.
是不是相等?,这跟cmp是一样的,这个只不过是说大于,大于现在可以应用于字符串,可以应用于浮点数,可以应用于点。
