这样的说法很不错,因为你让大家有所准备。你在告知他们你将采取下一步行动。
And this is the same periodic table that you're going to get in your exams, so it's good to practice doing your problem-sets with that periodic table so you're not relying on having the double check right there of seeing what the electron configuration is.
这也是你们考试时会用到的相同的表,这样你们就不会,所以使用周期表来做问题集,是很好的练习,这样你们就,不会依赖于再次确认,电子构型是什么了。
It's a good sign that this is logarithmic, and I'm going to come back in a second to why logs are a great thing.
为什么对数级复杂度是个好事情,让我们再来看一个算法,噢,抱歉是让我们再来看两个算法。
they're going to coordinate; that's very good.
太棒了,你们协调成功了
Now I isolated these cells maybe from the head region of the embryo, the region that's going to develop into the brain, so that would be a good place to look if you wanted cells that were going to develop into the brain.
现在我可以从胚胎的头部,分离这些细胞,从就要发育成为大脑的这些部位,这是取得你需要的细胞的绝佳位置,如果你想要发育成大脑的细胞的话
It was astonishing enough that somebody-- but perhaps understandable--that somebody in that situation would decide to take a class on death and then have himself, submit himself, to my getting up here week after week, there's no prospect for an afterlife, it's a good thing that we're all going to die.
某个,某个处于那种情况下的人-,会决定上一门有关死亡的课,然后一周接一周地让自己来上我的课,忍受我讲的没有来世,我们所有人都会死是好事,这是足够让人震惊的,但也许也是可以理解的。

And that's such a good question I'm going to defer it. I'm going to talk about it in a few minutes because that's actually--That speaks to the issue of the scientific assessment of Freud so I'm going to try to get to your question in a little bit.
这是一个好问题,我想压后一下,稍后来解答这个问题,因为这个问题实际上涉及到了,对弗洛伊德的科学评价问题,所以我一会再回答你的问题。
what good that's going to be, no matter how much money you make.
什么好处也没有,挣多少钱都没用。
Shielding is the term that's used, it brings up a certain image in our mind, and even though that's not precisely what's going on, it's a very good way to visualize what we're trying to think about here.
它带给我们一个确定的画面,虽然那不够精确,但当我们尝试去考虑它的时候,它确实是一种很好,的形象化的方式。
That gets us to the smart thief. Why is this thief smart? Because she took 600. And she learned 600 that in fact there is a good way to solve this problem. And that's what we're going to talk about next. And that's something called dynamic programming.
现在我们要当聪明的贼,这个贼为什么聪明呢?,因为它选择了,它知道这事实上是解决这个问题的好方法,这就是我们接下来要讲的,也就是动态编程。
That's the question we're going to try and address. If we can do this, this is good, because first of all, it removes any questions about what machine I'm running on, it's talking about fundamentally, how hard is this problem, and the second thing is, it is going to do it specifically in terms of the input. Which is one of the things that I was worried about.
这是一个我们接下来要去,尝试和解决的问题,如果我们能做到的话会很不错,因为首先,它解决了结果可能和我,运行的计算机有关系的问题,因为这从根本了告诉了,我们这个问题的复杂度,第二件事情,就是这种方法可以依据输入的大小来计算,而这正是我最担心的地方。
That might be a good way to do it but it's going to be more of a challenge because you might - you're going to have a lot of these non-coding sequences that are in the way.
这或许是个好方法,但这会带来更大的问题,因为也许--,会有许多不编码蛋白质的序列,干扰你的筛选
Good, so Steven, anticipating that Patrick is going to think that steven's a sucker but Patrick's going to cheat on him and produce too much, Steven's going to produce a best response to that and he's going to produce this quantity here.
很好,史蒂文预料到到帕特里克认为,自己是个傻瓜然后帕特里克会违约增产,那么史蒂文的最佳对策就是,生产这么数量的产品
And the reason for that is if the other person's going to go to Bourne Ultimatum I want to do that, and if the other person's going to go Good Shepherd I want to do that.
原因是,如果别人选《谍影重重》那我妥协吧,如果别人选《特工风云》我也妥协
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。
PROFESSOR: Good. So, it's going to be in 3, because that's the shortest energy difference we can have, 3 those 2 are inversely related, so it must be n equals 3.
教授:好,是3,因为它的能量差最小,红色的是我们能看到的,所以一定是n等于。
