It looks like we're still figuring out - this room was just renovated, we're still working out exactly how the electronics work. So normally we'll see a percentage of how many of you got it, but I'm going to say it was probably about 95% got the answer right.
这个房间刚刚装修过,我们还在试图搞明白,这些线路怎么工作的,如果正常的话,我们可以看到,你们回答正确的百分比,但我觉得你们,95%的人答对了。
So I'm going to show you a little trick for figuring that out.
因此接下来我会给你们讲一个,算出这个来的小把戏。
So, when I threw that thing up and you caught it, what you are doing mentally was immediately figuring out where it started and at what speed.

So it's not just knowing what genes or figuring out ways to look at gene expression, it's figuring out how this expression of key genes affects the fate of the individual.
所以我们不仅仅是要了解那些基因能致病,也不仅是要弄明白基因的表达方式,更要搞清楚这种关键基因的表达,如何影响个人命运
But if, over the course of the semester, you get better, then we will give, at the end of the semester, when we're figuring out your semester grade, we'll give the later, stronger papers more than their official weight.
但如果,在这学期中,这门课,你进步了,那么我们会,在学期末,我们算出你的分数后,我们会给那一两篇较晚时候写的,较好的论文比之前规定的更大的比重。
It's a secret number so that if Julius Caesar scrambled his message with the key 13, well, then the recipient had better know what that number is or realistically, -- and this is why it's kind of hard to buy -- into some of these age old algorithms, -- what would an alternative approach be to figuring out Julius Caesar's messages to his generals if he didn't know that secret number was 13?
它是一个机密的数字,以至于,如果凯撒大帝使用密钥13加密了它的消息,然后接收者最好知道那个数字是什么,实际上--这就是为什么很难,破解这些古老的算法-,有什么变换方法使凯撒大帝的将军,可以解密凯撒大帝的消息,如果他不知道,那个机密数字是13呢?
So, if you can't immediately know, and you don't all have periodic tables in front of you, so that's fine, but if you have a periodic table in front of you, you need to be able to count valence electrons, so work on that if it doesn't come naturally to you in terms of figuring that out.
如果你不能马上想到,而且你手上没有周期表,那还好,但如果你面前有一张周期表,那你就得具备从中查出价电子个数的能力,如果你不能自然而然地想到,请在这方面多下点功夫。
Why is it that when we see these law partners, or medical partners, or whatever it happens to be, or students together on a homework assignment, why is it we tend to get inefficiently little effort when we start figuring out the strategy and working through the game?
为什么这些律师事务所的律师,医疗合伙人或者其他类似的机构,还有一起做作业的学生,当我们研究过这些策略和博弈后,为何这样的组合往往是收效甚微的
We don't always want to go and solve the Schrodinger equation, and in fact, once we start talking about molecules, I can imagine none of you, as much as you love math or physics, want to be trying to solve this Schrodinger equation in that case either. So, what Lewis structures allow us to do is over 90% of the time be correct in terms of figuring out what the electron configuration is.
我们并不想每次都去解薛定谔方程,而且实际上,一旦我们开始讨论分子,我可以想象,你们中没有一个人,不管你有多么热爱数学或物理,会想去解这种情况下的薛定谔方程,总之,路易斯结构能让我们,有超过,90%,的概率判断出正确的,电子排布。
But in this game, playing best response to each other, figuring out that in fact the other guy is going to cheat on me, or the other guy is anticipating that I'm going to cheat on him, or the other guy is going to anticipate that I'm going to anticipate that he's going to cheat on ,me, etc., etc., will eventually drag us back to the Cournot quantity.
但在这个博弈中,互相采取最佳对策,预料到了对方会违约,或者对方预料到了我会违约,或者对方知道我会预料到,他会违约,以此类推,那么最终还是会达成古诺产量的
All the groups that stand to win or lose from it are all figuring out what it does to them and they're taking the positions out of self-interest So, I wanted to write something that was more perspicacious if I could manage that.
所有人无论赞同或者不赞同这个改革,都试图搞清楚这个改革对他们将有什么影响,从自身利益来讲,想搞清楚他们究竟能得到什么,所以,如果我可以的话,我更希望我能写一些独具慧眼的东西。
The idea is. It embodies the idea of putting yourself in someone else's shoes and trying to figure out what they're going to do, and then think about them putting themselves in your shoes, figuring out what you're going to do, and so on and so forth.
它揭示了以下过程的主旨,站在对方的立场上去换位思考,推测对手的行动策略,同时想象对手也会,站在你的立场,推测你的行动意图,如此反复进行
So the thing that I hope jumps out at you from this picture is no great guesses about figuring out this is a ?, so if the probability that the goalie's going to jump to the right is less than a ?, then the best you can do is represented by this green line, which is shoot to the right.
我希望大家都能从图中看出来,得出这一点的横坐标是?不难,如果门将扑向右路的概率,小于?的时候,此时你的最佳策略用这段绿线表示,即你应该从右路射门
figuring out there is no such thing as a free lunch but Markowitz tells us that diversification is a free lunch.
知道世上没有免费的午餐这回事,但马科维茨称分散投资是免费的午餐
So, either of those ways of figuring this out is the first guess of what goes in the middle will work pretty well.
因此,用上述任何一种方法来初步,估计哪个原子应该在中间都是相当好的。
So, whichever works best for you can do in terms of figuring out electron configurations.
所以不管哪一个你们用的最好,都可以写出电子构型。
it's clipping coupons and he describes his job as figuring out what the coupon is in an equity and if it's high enough he likes it.
就是获得票息,他形容自己的工作就是,发现在股票中的“票息“是什么,以及“票息“是否能够高到让他满意。
As far as I know, he doesn't publish he's not in the newspapers, but he's gotten the ear of the Treasury Secretary They spent many weekends together figuring out what should be done about the system and they wrote up a proposal.
据我所知,他从没出过书,也没有上过新闻,但他却有当财政部长的潜质,他花了数周的时间来搞清楚,对于现在的美国金融体系,该怎么改革然后书写成书。
