So what we're going to see is less shielding, which means that it will actually feel a higher z effective.
那么我们将会看到更少的屏蔽,这意味着将会感受到更大的有效核电量。
And so it depends on what it is that you are studying.
这个取决于你所学习的东西。
So what I want to point out is that it creates an effect that is exactly opposite of a bond.
我要指出的是,它造成的效果和成键正好相反。
So we need to revise our account of what it is on the physicalist picture to say that you're dead.
我们应该重新修改一下,物理主义学上对死亡的定义。
That is it. So you want high temperature bricks, what are you going to make them out of?
这就是它,因此你想要高温砖,你打算怎么做它?
But the accountants thought we did. So that's earnings Dividends is very concrete, it's what they send out.
会计明明显示赔了,这就是收益,股利则更具体,公司发多少是多少
All right. So let me start again by reminding you what it is that was done last time.
好的,我们开始上课,先回顾下上节课的内容
So that's what his tendency is, but if he does that, it's very bad news for his city.
所以他就会倾向于逃跑,但如果他逃跑了,那这对他的城邦来说可是个坏消息
Let's check it out. I've written a little bit of a test script here, so if we test cell sort, and I've written this so that it's going to print out what the list is at the end of each round, OK.
我们来检查检查,我写了一个小测试脚本,我写这个脚本来测试单元排序,它能够打印出每一轮结束后,链表的是什么样子的。
Okay. So that's what syncopation is and it isn't much more difficult than that.
好了,这就是切分音,也并非很难理解
But I hope to doing the next couple of lectures is giving you an idea what this class is about so that you can decide whether or not it is for you.
但希望几堂课后,你能有个大概印象,让你决定这门课是否适合你。
So, let's begin with another of those scenes on 213 that Nabokov points out to us, the Kasbeam barber. Why did it take him a month to come up with the Kasbeam barber? What's going on in this tiny snippet that's so important? So here it is.
那么,我们从213页纳博科夫向我们指出的另一个,场景开始:理发师加斯比姆,为什么他花了一个月的时间,来创造理发师加斯比姆的形象呢?这个小片段里,发生了什么重要的事情呢?我们来看这里:
So if we want to write out what that would be, it would just be to say that f minus is isoelectronic with neon.
那么如果我们把它写出来,它应该就是负一价的氟离子与氖原子是等电子的。
So, if we want to figure out the formal charge on the carbon, we need to take the number of valence electrons, so that's 4. We need to subtract the lone pair, what number is that? It's 2.
如果我们想算出碳原子的形式电荷,我们需要将价电子的个数,也就是四,减去孤对电子的个数,它是多少?是二。
People do need money and they go into business to make money; so let's make it clear, that's what the company is going to do.
人们需要钱,于是通过投资赚钱,明确的说这就是公司的任务
It is certainly possible, for example, that a quadratic algorithm could run faster than a linear algorithm. It depends on what the input is, it depends on, you know, what the particular cases are. So it is not the case that, on every input, a linear algorithm is always going to be better than a quadratic algorithm.
一个二次平方级复杂度的算法,当然也是可能跑的比线性复杂度算法快的,这取决于,你知道的,输入以及特定的案例,因此并不是对于每个输入,线性复杂度就一定会,比二次平方级复杂度的算法的表现要好,只是通常来说是这样的。
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。
It's not so much what's in the proposal as it is that this is the time for reconsideration.
这个计划的内容并不复杂,而如今正是一个反思的好时候。
Well, that's what happens but most of them made it all right So, that's the way it is in finance as well.
是这样的,但是大部分的飞行都是完美的,所以经济也是这样的。
But now I'm going to change it, so what is that new version of class say.
好,我又要提醒下大家,类是这个模板。
That isn't there. So it couldn't do it, so instead that's what append is for, is to stick things on to the end of the list.
也就是说不存在,因此没法进行指向绑定的,更改,因此这个命令并不像append那样,会在list的最后添加元素。
it's an easy calculation -- we're just taking the negative of the binding energy, again that makes sense, because it's this difference in energy here. So what we get is that the binding energy, when it's negative, the ionization energy is 5 . 4 5 times 10 to the negative 19 joules.
这个计算很简单-我们,只需要取结合能的负值,同样这很容易理解,因为这就是这的能量差,所以我们得到的就是结合能,当它取负值,电离能就是5。45乘以。
That expression, or that value, or that value, literally gets passed back out of that local environment to the value that comes back out of it. So in particular, none none what's solved returns is a pair.
这个表达或者说值,实际上是从那个局部环境中,输出来付给它的,所以solved返回的是一对值,它可以是一对。
So, we can think about what is it that we would call the ground state wave function.
我们来考虑一下,基态的波函数,是怎么样的。
But let's look for a slight variant of it, where greedy is not so good. And that's what's called the zero-one knapsack problem.
但是让我们找一找它的一些变种,在这些变种中贪婪算法用处不大,这些问题也就是0/1背包问题。
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。
we are the envy of the rest of the universe It's not so much that immortality, what the rest of them have, is unattractive or boring.
我们是宇宙其他生命羡慕的对象,不是说其他生命所拥有的不朽,是没有吸引力的,是让人厌烦的。
You want to write the specs so that everybody does in fact know what this piece of code is doing, and you're writing it each time around.
但是你得养成良好的习惯和编程风格,你得撰写规范说明从而保证,每个人都知道这段代码是干什么的。
