They different greatly in style. Genesis 1 is formalized, it's highly structured, it has the seven days and everything's paired up.
风格迥异,《创世纪》1,很书面化,结构严谨,什么东西都是成双成对的。
What's going on today with all these people dressed up and everything?
今天发生什么事了?这些打扮成这样的人在干什么?
OK. Binary search is perhaps the simplest of the divide and conquer algorithms, and what does that mean? It says, in order to solve a problem, cut it down to a smaller problem and try and solve that one.
好了,二分搜索也许是,最简单的分治算法,这意味着什么?,也就是说,为了解决一个问题,把它切割成小的问题,然后再来一个个解决。
No matter where you specify your electron is in terms of those two angles, it doesn't matter the angular part of your wave function is going to be the same.
不论你将,这两个角度,取成什么值,波函数的角向部分,都是,相同的。
And of course it was translated into English with that title, and then they changed it to-- what did they change it to in English?
当然这个名字是要被翻译成英文的,然后他们就把名字改成,英文翻译改成什么来着
Questions make a difference, which is why it is also important to ask the positive psychology question, which is the salutogenic question: ? "What is source of health? What is the source of success?
疑问引起改变,因此提问是非常重要的,提出积极心理学的问题很重要,也就是“健康创成“的问题:,“健康源于什么?成功源于什么?
If you look at the electrical force, the force of electricity, proton and electron or something, it's not proportional to the mass of either object.
如果你考察电作用力,即电现象产生的力,质子啊,电子啊,或者其它什么东西,这种力不和物体的质量成比例
Erik Others got a bio saying--thanks, Erik-- the speaker was rather cold and then it turned out later on when they're asked for their impressions of the speaker people are very much biased by what they first assumed.
其他人拿到的简介…谢谢,把演讲者描述成很冷淡,结果后来发现,当问及这些人对演讲者有什么印象时,人们都受到第一印象的偏向。
Right. So X get assigned the value of Y, but then Y gets the value of X; so what have you really done?
对的,X被赋值成Y的值了,然后Y获得了X的值,你到底做了什么呢?
Do you know when people usually dress like that?
你知道什么时候人们会打扮成那样吗?
Take the yolks and mix them in with the sugar and water No. Sugar and flour I guess is probably what I want, sugar and water is not going to do anything interesting for me here mix them into something else.
将蛋黄取出,把他们和上糖和水,不,我猜糖和面粉才可能是我想要的,糖和水没法儿为我,变出有趣的东西来,把他们混合成别的什么东西。
And then this means we'll have a total of sigma1s two electrons in our hydrogen molecule, so we can fill both of those into the sigma 1 s orbital, the bonding orbital. We don't have to put anything into the anti-bonding orbital, so that's great.
我们可以把这两个,都填入,轨道里去,成键轨道,我们不需要把什么放到反键轨道里去,这很好。
So, we're going to start with talking about bonding, and any time we have a chemical bond, basically what we're talking about is having two atoms where the arrangement of their nuclei and their electrons are such that the bonded atoms results in a lower energythan for the separate atoms.
那么,下面我们将从成键开始讲起,无论什么时候我们有一个化学键,基本上我们所讨论的,都是如何安排两个原子的原子核的位置,与电子的位置使得成键的两个原子,最终比分开时的能量更低。
And then, if I want to find out if something's there, I do the same thing. But notice now, hash is converting the input into an integer.
然后,我想查找出某些元素是否在列表中,我做同样的事,但是现在注意,哈希是将输入转化成一个整数,所以,其思想是什么?
What was the divide? The divide was breaking a big search up into half a search.
什么是分解?分解是把一个大搜索过程,分解成搜索一半的过程。
OK. So, what do I want you to take away from this? This idea of binary search is going to be a really powerful tool. And it has this property again, of chopping things into pieces.
从这里学到些什么?二分查找的思想,是一个非常有用的工具,我重复一遍,把问题拆成几部分来解决,那事实上,这里的增长率是多少?
So, what's the idea? If I know what my hash function does, it maps, in this case characters into a range zero to 256, which is zero to 255, I create a list that long, and I simply mark things.
我知道我的哈希函数做什么,在这个例子中,它将字母,映射成0到255的256个数字,我创建了一个这么长的列表,并且我只是简单的标志这些东西。
And specifically, when we give them a name it's very clear exactly which orbitals they come from combining, - we're calling these s p 3 orbitals -- that's because they come from combining 1 s orbital and 3 p orbitals.
特别的,我们命名它们,使得很容易看到它们是什么轨道结合而成的,我们叫这些轨道sp3轨道-,这是因为它们是由1s轨道,和3p轨道组合成的。
So to just preface what we're going to do next time, what would happen if I wanted to do sort, and rather than in sorting the entire list at once, I broke it into pieces, and sorted the pieces, and then just figured out a very efficient way to bring those two pieces and merge them back together again?
所以为了引导下一次,我们要讲的内容,如果我想做排序,而且不是一次吧整个列表排完,会发生什么,我把它拆成小的列表,然后把各个小列表排序,接着用高效的方法再把小的列表?
That's why in the earlier models of the atom, they're not horrible to sometimes think about just each n value as a little ring around.
这就是为什么在早期原子模型中,人们没有感觉到把每一个,n,都想象成,一个绕核的小圆圈有什么不妥。
> Initially, how come I don't have declare temp as what?
>,最初,为什么我不声明temp成什么?
So we end up with 3 s p 2 hybrid orbitals, so we can think about what would happen here in terms of bonding, and if we think about how to get our bonds as far away as possible from each other, what we're going to have is the trigonal planer situation.
因为现在sp2轨道有1/3的s特征,2/3的p特征,而不是3/4。,我们最后得到3个sp2杂化轨道,我们可以想象,成键时会发生什么,如果我们考虑。
