"We could succeed in Afghanistan and if the Pakistani government does not put its own house in order they could fail in their counter-insurgency anyway,".

If, in fact, a gold nucleus was this size here, we would need to use another lecture hall in order to find a place to put this nucleus right here.
那么这个实验就太诡异了,所以我们决定,把距离压缩一下,我们要考虑到这一点。
So what that means is that's how much energy we would have to put into a hydrogen molecule in order to get it to split apart into its two atoms.
它的意义,就是我们需要向一个氢分子中注入这么大的能量,才能将它分解成两个独立的原子。
Good programming style. All right? Things that we ought to do, as you put these pieces together in order to give you really good code.
优秀的编程风格,对不对?,为了得到真正优秀的代码,我们在把代码放到一起的时候。
Well, I just put them down in the order that came out of my head.
好的,我把它们,按照从我脑袋出来的顺序写下来的。
So if we can figure out the binding energy, we can also figure out how much energy we have to put into our atom in order to a eject or ionize an electron.
所以如果我们可以计算出结合能,我们也可以计算出,我们需要注入多少能量到原子中,去逐出或电离一个电子。
I merge. And the merge is, put them in order.
合并的过程是将它们按顺序摆放。
putting all those things together, if you looked at this question again we'd get 100% on it, 0 9 that our only option here is 0. 9, and that it's not the negative, it's the positive version, because we're talking about how much energy we have to put into the system in order to eject an electron.
把这些放在一起,你们再看一下题目,大家100%都能选对,我们唯一的选择就是这个,它不是负数,它是正的,因为我们说的,是要,把电子激发出来,需要提供的能量。
I don't put them in any strategic order.
我并没有给他们安排了任何有策略性的顺序。
Remember, because that 1 s orbital is all the way down in terms of if we're thinking about an energy diagram, we're all the way down here, so we have a huge amount of energy we have to put into the system in order to eject an electron.
还记得吧,因为1,s,轨道在能量示意图里,是在最底部的,我们要一直到最下面,所以我们要向这个系统注入非常大的能量,才能打出一个电子。
