It said: "I now request to meet with you at such time and place as you may name to discuss the terms of the surrender of this army."

So we left off last time with looking at a bit of coding and teasing you with the upcoming problem set.
我们上次讲到了查看一些代码,并且给你们带来这下面的习题。
-
If you have a project at work that is taking a lot of time and the deadline is coming up very soon,
如果你在工作上接手了一个项目，已耗费了大量时间，而交付日期马上就要到了，
-
I can't go down to the registrar and say, you know, I'd really like to do it at another time.
我不能去和登记的人说，我想要换个时间。
-
You can take these big risks of time, and if at the end of the day there's nothing to detect, you still know how to build a detector.
如果最后你什么都没测到，你至少知道了,怎么造一个探测器,所以如果你们。
-
We normally think of teaching as a synchronic process, you and I are in the same place and in the same time while we are learning, when in fact at least right now we are not.
我们通常设想教学是限于一时的过程，你我在同一地点,同一时间学习，但事实上至少现在就不是这样。
-
You're in the process of becoming more mature, more differentiated and you're losing potential at the same time.
你正在成熟的过程中,分化得更加彻底,同时也失去了一些潜能
-
Can you think of any behavior thing that people might do that would at the same time suppress weight and cause bad health consequences?
大家能想到有什么行为是,一方面抑制体重,另一方面引起健康问题的
-
All right? A linear search, I start at the beginning of the list and walk all the way through it. All right, if I'm lucky and it's at the low end, If it's not, if it's at the far end, I've got to go forever, and you saw that last time where this thing paused for a little while while it actually searched a list this big.
如果很幸运就在开头,那运行起来很快，如果是在末尾,那就一直得走到头，上次看到了,如果搜索空间很大,程序都会暂停一会,好的，那我希望你们。
-
All of you, at the end last time, wrote down this number and handed them in so we had one number, one strategy choice for each person in the class.
上节课大家都交上来了一个数字,所以每个人都有对应的数字,这就是每个人都有一个策略
-
There's no change in them, and then we also looked at some at non-state functions, work and heat, and saw that those aren't zero going around a cycle. Of course you can do work in a cyclic process, and heat can be exchanged with the environment at the same time.
它们不会有变化，然后我们研究了,一些非态函数，功和热量，并看到,沿着循环行进一周的话,它们并不是零，当然你可以在,一个循环过程中做功，而同时热量可以在系统,与外界环境之间进行交换。
-
For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.
例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
-
and at the same time, you could be fluent to other professionals all over the world.
同时，你能跟世界各地的专家交流。
-
And you had the best time eating and talking and just looking at life.
你们俩都非常享受美食，愉快地聊着天，交换对生活的看法。
-
What happens is suppose you have the flu and you get very nauseous and then at the same point you eat some sashimi for the first time.
假设你得了流感，感觉非常恶心,与此同时，你又第一次吃了生鱼片。
-
But if you look at the tech fund category, the difference between the dollar-weighted and the time-weighted returns--this is over a ten-year period -is 13.4% per annum; that's stunning.
但是如果你关注科技投资基金,十年间,货币加权回报率,和时间加权回报率间的差距,是每年13.4%,这是非常夸张的
-
Even if you're in a room or a battlefield where people are dying at the same time as you, to your left and your right, dying is not and cannot be something that is a joint undertaking.
即便你处在房间或者战场上,有人和你同时同地死亡，就在你的身边死亡，死亡也不是你们共同完成的。
-
So you will learn all of them at the same time, and
所以你同时要学习好几门学科。
-
Next time to the Enlightenment and some people whom you might not think of at first glance would seem terribly enlightened.
下一次课是关于启蒙运动的,有些你们乍看之下绝对想不到的人物,却引领了那个时代
-
We won't come back to it at least for the moment, but you see that it's mercifully short, and as time passes we will do some rather interesting tricks with it.
至少我们这节课用不上，看，这篇故事很短，过一段时间我们会针对它做一些很有趣的练习。
-
This is going to end up at a different temperature by the way. You saw this last time in a slightly different way. Last time what you saw is we compared isothermal and adiabatic paths that ended up at the same final pressure, and what you saw is that therefore they ended up in different final volumes.
末态温度是不一样的,上次你们看到的,和这个有一点不一样,上次我们比较的是末态压强,相等的等温过程和绝热过程,因此它们的末态,体积是不一样的。
-
But how carefully you estimate will determine in part how good your ultimate records are so please try to be as careful as you can, and then pick the closest option if you can't find the exact food that you're eating at that time.
你估计的仔细程度,在某种程度上,也会决定最终结果的准确性,所以请尽可能谨慎,如果找不到完全对应的食物,请选择和你当时所吃食物最接近的选项
-
Sometime after you've eaten, say you had this Snickers bar at lunchtime and you don't have time to get anything else to eat during the day, your blood glucose level will go down.
有时候你们吃完饭以后,午饭的时候你吃了士力架,在这一天当中你又没时间吃别的东西,你的血糖水平就会下降
-
So in that numbers game, the game when all of you wrote down a number and handed it in at the end of last time, the players were who? The players were you. You'all were the players.
在那个数字游戏中,你们每个人都写下了一个数字,然后在下课前交了上来,谁是参与人呢,你们就是参与人
-
You could take weights on people measured over a period of many years and look at the variability over time in weight and then link it to things like heart disease and cancer, and I'll come back later and talk about the results of that particular study.
我们还可以得到人们很长一段时间里,每年的体重数据,观察体重随着时间变化的变动,并将观察结果与心脏疾病和癌症联系起来,我等一下会告诉大家这项研究的结果
-
In contrast when we're looking at a p orbital, so any time l is equal to 1, and you look at angular part of the wave function here, what you see is the wave function either depends on theta or is dependent on both theta and phi.
相反当我们看ｐ轨道时，任何时候ｌ等于１,你们看它的角向波函数，你们可以看到它要么是和theta有关,要么是和theta和phi都有关。
-
And we hope that at the end of the class, every time you're confronted with some technical problem, one of your first instincts is going to be, "How do I write the piece of code that's going to help me solve that?"
并且我们希望到了期末，每当你要面对一些,技术问题的时候，你们的本能之一将会是：,“我怎么才能编写一个代码,来帮我解决这问题？“
-
So, you remember from last time radial nodes are values of r at which the wave function and wave function squared are zero, so the difference is now we're just talking about the angular part of the wave function.
你们记得上次说径向节点在,波函数和波函数的平方,等于零的ｒ的处，现在的区别是我们讨论的是,角向波函数。
-
You see how long you are in the air and the whole time you are in the air, you are traveling horizontally at this speed.
你可以知道在空中停留的时间,当你在空中运动的时候,你一直以这个水平速度在运动
-
And in particular, we left you hanging at the end last time.
上节课我们还有一个问题还没搞定
