Now, it's interesting because the other four books of the Pentateuch never mention a king. In Genesis through Numbers none of the legal materials say when you have a king this is what he shall do.
有趣的是，摩西五经中的其他四本经书,从来没有提到过国王，从《创世纪》到《民数记》,从没有一份正规的材料说,当你有了一位国王后，这些就是他应该做的事情。

OK, says it says enter a float. I give it something that can be converted into a float, it says fine. I'm going to go back and run it again though. If I run it again, it says enter a float.

So you'll notice in your problem-set, sometimes you're asked for a number of orbitals with a set of quantum numbers, sometimes you're asked for a number of electrons for a set of quantum numbers.
希望你们在做习题的时候注意到，有时候问的是拥有,一套量子数的轨道数，有时候问的是拥有一套,量子数的电子数。

Frequencies, how many times you go around, f is revolutions per second It's called the angle of velocity.

So this is very similar, this is a kind of recursive thinking we talked about earlier, where we take our problem and we make it smaller we solve a smaller problem, et cetera.
我们则跳过比猜想数小的那个区间,然后我们重复这一过程,跟之前我们讲过的，递归思想非常类似,我们解决问题的时候,先把问题一步步变小，然后解决小问题。
-
So, if you look at all of these, we have full octets for all of them, and if we count up all of the valence electrons, it's going to be equal to our number 26 here.
那么，如果大家看看所有的这些，它们的“八隅体“都填满了，而如果我们来数一数价电子的总个数，它应该就等于我们这里的二十六。
-
That makes sense because we know that every single electron has to have its own distinct set of four quantum numbers, the only way that we can do that is to have a maximum of two spins in any single orbital or two electrons per orbital.
那个讲得通,因为我们知道每一个电子,都有它自己独特的量子数,我们能做的唯一方式是,在任一单个轨道中最多有两个自旋电子,或者每个轨道有两个电子。

It weights big deviations a lot because the square of a big number is really big.
使偏离的权重更大,一个数的平方是一个更大的数
-
We have a couple of passages, one in the book of Numbers, one in the book of Job, which describe this condition in a way that identifies it with death. An aborted fetus is often not often, it happens once in the book of Job.
有两篇文章，一篇在《民数记》,一篇在《约伯记》里，描述了这种,意味着死亡的状况，比如说，一个被流产掉的胎儿就,但这些例子不多，只在《约伯记》里出现了一次。

I'm given an integer that's a perfect square, and I want to write a little piece of code that's going to find the square root of it. All right so I'm cheating a little, I know it's a perfect square, somebody's given it to me, we'll come back in a second to generalizing it, so what would the steps be that I'd use to walk through it?
完美平方数的整数，我想写一段代码来求这个数的平方根,好，我这儿有点儿作弊了,我知道这是一个完美的平方数了,他们给我的，我们后面会讲怎么产生这个数的，那么我想解决这个问题,需要什么步骤呢？

So Rituparna tries to prove to him his abilities and he says, see that tree there, I can estimate how many leaves there are on that tree by counting leaves on one branch.
所以睿都巴若那就试图证明自己的能力,他说,看那边的树,我只需数一根枝杈上的叶子,就能估算出树上叶子的总数

If you have a bond with an interest rate of 4.375% -that's not an easy one to divide by two but you would get half of that every six months until maturity.
如果你持有一种利率为4.375%的债券,这个数除以2有点难算,而在债券到期前,每半年你能得到4.375%一半的券息
-
But that little short hand there is doing exactly the same thing. It is adding that value into some digits and putting it back or signing it back into some digits. And I'll walk through that loop and when I'm done I can print out the total thing does. And if I do that, I get out what I would expect.
加上得到的这个数的,但是这个缩写声明其实是进行了同样的操作,它把我们得到的这个数加到一个数上面去,然后用和对这个数进行了重新赋值,在循环中会去遍历字符串，当完成循环后,程序会显示数字的总和，如果我运行，这个程序的话，我会得到我期待的结果。
-
And also I wanted to mention in terms of checking your Lewis structures, regardless of what they are, you should always go back and I had 10, and then count 2, 4, 6, 8, 10, because you always need to make sure you have the same number of valence electrons that you calculated in your actual structure.
我还想提一点关于检查,你的路易斯结构的建议，不管它们是什么，你总是应该回去检查一下,我有十个，然后数一数，二，四，六，八，十个，因为你总是需要确保实际价电子的数量,与你在结构中算出的数量相等。
-
You have n branches on the tree and you count the number of leaves and sum them up.
一共有n根树枝,你数了叶子的数量然后把他们加起来
-
I'll get rid of Fibonacci here, we don't want to bother looking at that again.
我在这里会注释掉Fibonacci数，我们不想再看一遍。
-
So, Ed Asner has a Bacon number of one.
所以Ed，Asner的Bacon数为一。
-
But in this next passage, which is Numbers 11, Moses is the one who is impatient with the Israelites' constant complaints and lack of faith, and he's ready to throw in the towel.
但在下一篇《民数记》11中，摩西成为了那个对犹太人不停的抱怨，缺乏信仰,没有耐心的人，他准备认输。

What's the biggest number you can represent with three decimal digits? Pardon?
你们想用这3个十进制数表示什么？,请再说一遍？
-
The one thing you want to keep in mind though is that Hertz does not actually mean inverse seconds, it means cycles per second. So, if you're talking about a car going so many meters per second, you can't say it's going meter Hertz, you have to say meters per second.
写成5每秒，或5赫兹,你们要记住的是赫兹,并不等于秒的倒数，它是每秒的循环数，如果你们说,一辆车一秒可以走多少米,你不能说它走了米赫兹。
-
Count the number of primitive operations in each step.
数一数每一步中的基本操作,好的，如果我们看看这段代码。
-
And the next number is the sum of the previous two.
是前两个的和,再下一个数是前两个数的和。
-
Knowing that, I'm going to say, OK, how many pigs are there, well that's just how we're, however many I had total, minus that amount, and then I can see, how many legs does that give, and then I can check, that the number of legs that I would get for that solution, is it even equal to the number of legs I started with, ah! Interesting. A return.
它将给我返回头的总数，知道了这些之后我可以说好了,有多少猪呢，无论有多少组鸡的数目，我只要用总数减去那个值,之后我就可以知道一共有多少条腿,然后再把这个值和题目中的腿数相比较，看它是否等于一开始的腿数,啊！真有趣，有一个返回值。
