By the time you get to the end of the term, you're going to be dealing with some fairly complex things, so one of the things you're going to see is, we're going to make heavy use of libraries, or code written by others.
当你临近期末的时候,你们将要解决一些,相当复杂的难题,因此你们将会看到的其中一点是,我们要充分利用图书馆,或者别人编写的代码。
All right, next time we're going to talk about a much better scale, which is the ideal gas thermometer and how we get to the Kelvin scale.
好,下次我们,会讲一种好得多的温标,关于理想气体温度计,和开氏温标的导出。
Not to harp on the mathematical features of this, but cubing, AX*X*X you know, if you're starting to do AX star, X star, X, every time you want to cube some value in a program, it just feels like this is going to get a little messy looking, if nothing else.
不要总是说这个的数学特性,但是体积,你们懂的,如果你开始做,在一个程序中,每次你想算几个数值的体积,感觉它就变得,有一点凌乱的,如果没有其他的。
So rather than go through this again a whole third time, I've gone through it once in quantities and once in prices, I'm going to get you guys to do it this time by having you do it on a homework assignment.
与其从头到尾再做第三遍,我已经从产量和价格角度从头到尾做过了,我将让你们自己,在家庭作业中完成这个工作
And so the first thing we're going to spend a fair bit of time on is trying to get clear on what's a person?

You're going to get these personality tests all the time and the personality tests-- You're applying for a business and " one of the tests says "I like to steal from my bosses " Well, I don't think so No That's a little IQ test right there ? So, the question is how do you avoid that problem?
你们以后会做很多这样的性格测试,例如:你求职时做性格测试,其中一题是“我想偷老板的东西“,不,我不会,这相当于一个智商测试,问题在于,你怎么避免那个问题?
You are not going to get it out of me this time, like you always do.
这回你没法从我嘴里捞到半点消息,就像你自己经常严守秘密那样。
So that way you can have an idea if, oh, I do really understand this but I'm a little bit slow, maybe I need to practice this one type of problem a little bit longer so I can get up to speed so I'm going to be able to get through all this in terms of the exam time.
这样你就可以知道,假设,噢,我真的懂这个,但是我的速度有点慢,或许我需要在练习这个类型的题目上,多花一点时间,这样我就可以提高自己的速度,可以全部做完,在考试规定的时间内。
One more time and we need- we're going to get our third in.
再来一次,我们把三度音程加进去
I'm not going to get into in too much detail because we don't have the time, there are other places where you can read about it if you're interested, but I'll just give you a little information on this.
我不会讲太多的细节,时间不太够,如果你们感兴趣,很多资源可供参考,我会给你们点提示
All right? If you run it, you have a sense of the upper bound, about how much time it's going to take to do this computation, so you're not going to get surprised by something showing up.
第一,这样做意味着没有意外了对不对?,你去运行程序,你已经大致知道运行时间的上限了,因此发生任何事情,你都不会吃惊了。
The sum of path number 2 and path number 3 get me to the same place, so the energy change by going through this time path, this intermediate point here back all the way to final state should be the same the red path.
而经过路径2和3可以3,到达同样的末态,因此经过路径,2和3带来的能量的变化,与路径1带来的,能量变化相同。
So we're to assume we can get to any piece of data, any instruction in constant time, and the second assumption we're going to make is that the basic primitive steps take constant time, same amount of time to compute. Again, not completely true, but it's a good model, so arithmetic operations, comparisons, things of that sort, we're all going to assume are basically in that in that particular model.
因此如果我们假设在恒定的时间内,我们可以取得任何一块数据,任何一种数据结构的话,我们要做的第二个假设就是,基本的原始操作计算花费的时间是恒定的,这个假设也不是完全正确的,但这个模型其实挺不错的,因此算法操作,比较,这一类的事情,我们在这个特定的模型中都假设是基本的,操作,花费的时间是恒定相同的。
