如同我已经提过的，我们的关键目标和战略目标都是为了,帮助你像一个计算机科学家一样思考。

And so I was collecting from friends and colleagues' computers all sorts of logs that monitored the kind of low level activity that was happening on their computer.
因此我从朋友和,同事的计算机上收集各种各样的日志,这些日志用来监控,他们计算机中的低能级活动。

0 PROFESSOR: Thank you. This is 6.00, also known as Introduction to Computer Science and Programming.
教授：谢谢，这里是6。,也就是大家熟知的,计算机科学和编程导论。

Economics and Game Theory are now essential tools for understanding human thought and human behavior— those issues connecting to philosophy, computer science, anthropology, literature, theology, and many, many other domains.
经济学和博弈论如今已经成为了,理解人类思维和人类行为的重要方法,这些问题涉及哲学,计算机科学,人类学,文学,神学,以及许多其他的科学领域

I was deciding between political science at the time and computer science because I have always been fascinated by cities and at some point want to maybe potentially go into government I'm still not quite sure if I have more effect there or more effect in programming.
我那时要在政治学和,计算机科学,中做出选择，因为,我一直为城市着迷,我潜意识里有些想去政府工作,我并不确定我以后在,政治上更有成就还是在编程上更有成就。

Jin says he is a sophomore in computer science and he has science fiction in mind and plus machines So you have some immersion in philosophy.
杰，他大二，学计算机科学,他满脑子都是科幻小说和机器,所以你对哲学有点了解。

So those are in fact the patterns of zeroes and ones, the bytes that would have been outputted had I hello c remembered to download the compiler to this computer and run it on that little hello.c file.
这些都是0和1的模式，如果我记得下载编译器到计算机上的话,我们就能运行下这个,然后看看输出的字节。
-
To do that, we need to describe: not only, what are the primitives, but how do we capture things legally in that language, and interact with the computer?
为了达到这个目的，我们需要描述：,包括程序基本的东西，以及怎么在这种语言中，做我们想做的事情并和计算机交互？
-
That's the question we're going to try and address. If we can do this, this is good, because first of all, it removes any questions about what machine I'm running on, it's talking about fundamentally, how hard is this problem, and the second thing is, it is going to do it specifically in terms of the input. Which is one of the things that I was worried about.
这是一个我们接下来要去,尝试和解决的问题，如果我们能做到的话会很不错，因为首先，它解决了结果可能和我,运行的计算机有关系的问题，因为这从根本了告诉了，我们这个问题的复杂度，第二件事情,就是这种方法可以依据输入的大小来计算,而这正是我最担心的地方。
-
It turns out that in a lot of languages, C included, you the programmer knowing a bit about how the computer works and the language works, can exercise more fine-grained control.
结果在包括C语言的很多语言当中，你作为一个程序员懂得了一些计算机的工作方式,和语言的处理方式，可以更精确地控制运用它。

If you are interested by contrast in new Aces and fun toys our friends at Aces which is a hardware manufacturer which makes things like motherboards which are the innards of computers and other things.
与之相比，如果你对新鲜和,有趣的玩具感兴趣，像计算机硬件的制造商,他们主要生产主板之类的东西,主板是计算机和其他一些设备的内部结构。

So, it looks like the curry and some other items were really precisely defined in terms of price and this is of course has generated this receipt - by some computer, some cash-- cash register and they just didn't account for the inherent imprecision so here is a perhaps real world incarnation of that.
看起来咖喱,和其他一些东西都被明确地定价,这当然可以,通过计算机-,收银机生成这份收据，而且它们并不对,其内在的不精确性负责,这可能就是现实世界中的一个典型。

But the point is that how is Facebook, how is Amazon possibly going to communicate securely with you or your laptop using cryptology if you both have to know the same secrets.
关键是Facebook是怎么样，亚马逊是怎么样安全地和你或你的计算机,使用加密技术进行交流的，如果你们两个都,知道那个同样的密钥。

Now, unlike high school math or in algebra Z where you call things X and Y and Z, in programming, in computer science, you're actually dealing with humans where it's useful to have a variable name that's more descriptive than X and Y and Z.
不像高中数学或者代数中,称为X和Y和，在程序设计和计算机科学里，你实际上是在和人打交道,在这里有个描述性比xyz更强的,变量名称是很重要的。
-
So with the problems, that is where you really will get your hands dirty and truly immerse yourself in this world of computer science and programming.
带着这些问题，你就能深入研究,这真的可以使你沉浸到计算机科学,和编程世界中。
-
But in fact, it is not. And so, something I find myself repeating over and over again to myself, to my graduate students, is when you get an answer from the computer, always ask yourself, why do I believe it?
但是实际上，它并不是，因此，我一直一遍又一遍的重复的,给我自己和你们这些学生的就是,当计算机给出一个答案后，一定要问问自己为什么要相信这个答案？
-
Well really, the things we've looked at thus far can you do after just a semester of this kind of material and exposure to this particular world.

So on the left hand side of this particular languages environment I have some puzzle pieces and they are shaped and colored ; in a manner that hints out their functionality; any blocks that tell the Cat as we'll see in a moment, what to do something happen to be orange.
在这个程序语言界面的左手边有一些拼图,他们的形状和颜色代表他们的功能,我们马上就能看到;,任何一个给计算机发出指令的图块，都是橙色的。

But that's not enough because computers at the end 1 of the day only understand 0s and 1s and what you and is clearly not a collection of 0s and 1s.
但是仅仅这样是不够的，计算机,最终只会认识0和,你现在得到的，c的文件显然不是0，1的合集。
-
But one of the teaching fellas also passed long to us recently, a little real world example of what happens when you're not mindful of various data types and you're not mindful of the imprecision that's inherent in representing data in a computer, at least using a language like C and low level primitives like floats and even doubles.
最近有个助教告诉我们，一个现实世界中的例子,当你不注意各种各样的数据类型,也不注意在计算机中表示数据时,其内在的不精确性，至少在用像C语言,和float甚至double型数据时，那将会发生什么？
