For now I want to tell you a little bit about what open course ware is and also share with you some work experience with our first public launch of the site.

现在我想谈谈,什么是开放课程软件,并且与你分享一些,第一次开放这个网站的工作经验。

And this course in particular isn't at the end of the day about programming even though that is in fact how you will spend a good amount of your time and the skill that you will in fact walk away with.

尤其特别的是,这门课程最终的目标,不是教会你编程,尽管编程会花费你们大量的时间和精力。

The first question you need to ask yourself is why do you want, or why are you thinking about taking this course?

各位需要问自己的第一个问题是，为什么要，为什么想研读这门课程？

She also loves astronomy, which is incidentally an interest of mine too, but you won't hear about it again in this course.

她还喜欢天文学,巧合的是,这也是我的爱好之一,但在这节课上我也不会提及

The precision of that,of course, is not to be taken seriously, but it gives you a general idea of when we are talking about.

当然,这个时间的精确度,并没有经过严格考证,但是它使我们对这件事的时间有个大体的概念

All right. So that's what the subject matter's going to be, and I'm going to tell you a little bit about how the course is organized.

好了,以上就是我们主要的学习内容,接下来,我稍微讲一点,咱们的课程安排

I want to talk about the goal of the course, what it is you'll be able to do at the end of this course when you get through it, and then I want to begin talking about the concepts and tools of computational thinking, which is what we're primarily going to focus on here.

我想讲讲课程目标，也就是当你们完成了这门课时,应该达到的程度，接下来我想开始谈谈,计算思维的概念和方法，即这门课程的核心内容。

So gone through all of these dimensions, because I want you to make sure that you could understand that when you are creating an entire course or an entire educational engagement, it is very important to think about both the explicit and the implicit purposes.

在分析完这些方面后，我希望你们,务必明白,在设计整个课程,或是教育参与时，考虑教育的表层目标和,深层目标是十分重要的。

So one of my purposes of this course is to get you, whether you study Biomedical Engineering after this or not, excited about the subject so that you start thinking about how you could innovate in this area where lots of problems are still left to solve, so I'll see you on Thursday hopefully.

我这门课的目的之一就在于,无论你们继续学习生物医学工程与否,我想激发你们对这门课的兴趣,思考在这个仍旧存在诸多问题的领域中,你们能做出什么样的创新,希望在周四的课程中再见

That's an important observation, and as we get to the part of the course we talk about computational complexity, you'll see that what we really care about is not how efficient the program is on easy problems but how efficient it is on hard problems.

我们已经学习了这门课程的一部分了，我们要开始认识到,计算的复杂度这个概念，你会学习到我们在乎的并不是,算法在简单问题上的工作效率,而是解决复杂问题的效率。
