Well, I'm going to get back, let's just draw a bigger square than usual that's roughly four times the size.
嗯,返回的是,我画一个更大的方形,大致上是4倍的大小。
Times Square... Well, Times Square has gone through a lot of changes.
时代广场……好吧,时代广场发生了许多变化。
"Well we are talking approximately about 99 square miles, and its sovereign base area which is land which is effectively governed by the UK and has an on-island administration that acts on behalf of the Queen in managing and governing that land,".

OK. And how do I create them? Well, the representation is, following a square bracket, followed by a sequence of elements, separated by commas, followed by a closed square bracket.
就是一个有序的序列,好,那么我们怎么创建元组呢?,好,表达式是,一个方括号,后面是一系列的元素,以逗号分开,以一个闭方括号结束,这就是我刚才所说的。
Well, int is almost always 32 bits at least so far as we've seen so, in fact, any time I draw a pointer hence force I'm just going to draw a square as well because they are, in fact, the same size usually in memory.
嗯,int几乎总是32位的,至少我们至今所看到的是这样的,每次我用一个正方形表示一个指针,因为实际上他们,在内存中的大小是一样的。
And what here is just a graph of the 1 s wave function going across some radius defined this way, and you can see that the probability - well, this is the wave function, so we would have to square it and think about the probability.
这里是,1s波函数,沿这个方向的图,你们可以看到概率,这是波函数,所以我们可以把它平方,并想成是概率。
We have two, well, let me draw this is as a square.
我们现在又两个,让我用方程式写出来。
Well, Trafalgar Square's very commercialised now.
特拉法尔加广场现在非常商业化了。
Remember, I said when we do a bisection method, we're assuming the answer lies somewhere between Well, what is the square root of a quarter? It is a half.
记住,我提过当我们用二分法的时候,我们假设答案处于,上边界和下边界之间,0。25的平方根是多少?,是0。5。
If I say x is 2, I want to know, what's the square root of 2, well if you're enough of a geek, you'll say 1.41529 or whatever the heck it is, but in general, this doesn't help you find the square root.
如果我说X等于,我想知道,2的平方根是多少,那么如果你足够书呆子你就会说,1。41529或者随便什么玩意儿,但是大体上,它不会帮你算出平方根。
int Y Well, I said int X and int Y; so that gave me one square here called X, one square here ; or wherever, called Y, done, one was put in here; two was put in here, and then I called this function swap.
好的,我声明了int,X,和;,然后我这里有个正方形叫做X,一个正方形,叫做Y,完成,1放在这里;,2放在这里,然后我调用这个swap函数。
Square root of 16, and my plot basically shows it crosses at 4 and-- well, I think that's minus 4.
我的图清楚的显示这个函数,在4和-4两个点和x轴交合。
Well, all this time int on the blackboard I always draw an int as a square.
嗯,向来,我在黑板上用一个正方形表示一个。
Well I'm relying on the contract, if you like, that the manufacturer of square root put together, which is, if I know I'm giving it two floats, which I do because I make sure they're floats, the contract, if you like, of square root says I'll give you back a float.
好吧我能靠一些类似合约来保证,如果这么说你喜欢的话,其实就是当求平方根的方法,获得了两个我已经确认了是浮点数的数后,这个类似合约的东西就会保证,返回一个浮点数。
OK, once it gets to the end of that, what's it going to do? It's going to come down here and, oh. What's that doing? Well I cheated when I started. I said, somebody's giving me a perfect square, I'm looking for the square root of it. But suppose 15 I gave this thing 15, and asked it to run.
好,一旦到了循环的最后,程序会去做什么?程序会跳到这里来,噢,这是干什么的?好吧,当我开始的时候我有点小作弊的意思,我说过,我得到了一个完美的平方数,我要求这个数的平方根,但是假设下我得到的数是。
