What I'd like to at last introduce to you is the exercise that we are going to be doing together.
最后我要向你们说明的,是大家要一起,做的练习。
people that are going to be industry professionals and that's what takes you along the way.

There, Newton doesn't tell you what forces are going to be acting on a body in a given situation.
在式子里,牛顿没有告诉你,在给定条件下,有哪些力,作用在物体上
I mean post 911 we had circumstances that a lot of people, unless you're actually dealing with it, you wouldn't really be able to understand what people are going through.
11之后我们的情况是,除非你真的在应对这件事,许多人都不是真的,能够了解,我们经历了什么。
That goes back to that idea of sort of discipline coding. It's easy to have assumptions about what you think are going to come into the program when you writ it. If you really know what they are use them as search, but if you think there's going to be some flexibility, you want to prevent the user getting trapped in a bad spot, and exceptions as a consequence are a good thing to use.
这又回到了规范编码的想法上来了,在你写代码的时候考虑,什么会进入你的代码的思考是简单的,如果你真的知道,他们是用他们来做搜索的,而你希望有一定的灵活性,你想要阻止用户,陷入一个艰难的境地,那么异常是非常实用的。
The idea of a forward rate is that, implicit in that term structure is also a quote for the one-year rate, one year hence, because if you look at the two-year rate, can't you infer back what interest rates are going to be in one year?
远期利率隐含在期限结构中的,一年期利率报价,起息日是第二年初,因为如果你知道了两年即期利率,就可以很自然地推出一年即期利率
So that's what we are going to focus on, and you will find out that the laws of physics for this entire semester certainly can be written on one of those blackboards or even half of those blackboards.
这就是我们的课程重点,而且你将来会发现,整个学期的全部物理定律,最多也只能写满一块黑板,或者半块黑板
In general, good programming style says you put in comments that are going to be valuable in helping you as a reader understand what's going on inside of the code.
通常来说,优秀的编码风格意味着,你要放进去的注释,在帮助代码阅读者,理解代码内部,是怎么工作的。
