So now that we begin to have this ability to express strings in memory, to understand what they are, we can start to apply actually real-world algorithms to them.
现在我们开始用这个技能来在内存中表达字符串,来理解它们是什么,我们可以开始,我们可以对其使用实际的,现实生活中的算法。
They wake up.We need some way to refer to these people, so we can start talking about who they are.
他们醒来之后,我们需要让人们,了解这种情况以便探讨他们是谁。
Well, a few details, a few building blocks we can start using in more compelling ways.
注意一些细节,我们可以更灵活地运用之前的一些,构建程序块。
We can start having complex expressions, you can imagine we can have things are lots of parens, and all sorts of things in it. Yes, question.
我们可以开始写复杂点的表达式了,你可以想象,我们有一个很多括号的表达式,里面有各种各样的东西,什么问题。
For us, we can start not so all the way back at Classical Greece, but with Alexander the Great, and the beginning of Hellenization; that is, the Grecization of the eastern part of the Ancient Mediterranean.
我们不必追溯到古典希腊时期,而从亚历山大大帝及希腊化初始讲起;,就是古代地中海东部地区的希腊化。
From this perspective, we can start to answer some interesting questions at least about nonhumans.
从这个角度,我们可以回答一些有趣的问题,至少关于非人类。
But let's put down some payoffs so we can start talking about this.
但我们需要搞清收益后才能分析此博弈
We can start taking derivatives of this with respect to time.
我们首先来对时间求微分
So we can start. This distance here is r naught.
所以我们开始。这里的长度是r圈。
But instead in this chemistry course, I will just tell you the solutions to differential equations. And what we can do is we can start with some initial value of r, and here I write r being ten angstroms. That's a good approximation when we're talking about atoms because that's about the size of and atom.
但在这个课里,我会直接,告诉你们微分方程的解,我们可以给距离r一个初始值,我这里把r取10埃,当我们讨论原子时,这是一个很好的近似,因为原子的尺寸。
We can't just smash things and start all over, we have to design a system of risk management.
而不是简单地打破一切再重新来过,我们应当设计一个好的风险管理体系。
Think of that. And while you're thinking about it you can start reading Plato's Apology for Socrates which we will discuss for class on Wednesday.

所以我劝大家赶紧去领取,越快越好,这样等会讲课时大家都能用上
We'll talk about cells and how they work, how cells in different parts of the body are different, why, and how they contribute to tissues at a very sort of simple level so that you can understand this as we start thinking about using cells for engineering purposes.
我们将会谈论细胞,它们如何工作,身体不同的部位细胞有怎样的不同,为什么它们有所不同,以及这些细胞如何,以十分简单的方式形成组织,这样当我们开始考虑用细胞,来满足工程目的时,你会更容易理解
Now, once we've got that, we can start doing things.
好,我们可以开始做了。
