When we did the spring, we had this theory of Hooke's Law that told us something, and we built a simulation, or built some tools around that theory.

当我们写弹簧程序的时候,我们有胡克定律来告诉我们原理，然后我们建立了一个仿真模型，或者说是在这个理论基础上建立了一些工具。

Now the difference between the two models, the health model and the disease model is more than just semantic.

两种模型，健康模型和疾病模型的差异,不仅仅是语义上的。

However, as you know, we didn't stop at the plum pudding model, which is good, because it's a little goofy, so it's nice to move on from that and move on we did.

我们并没有,停留在李子布丁模型上，虽然它很好,但这个模型有点傻。

So, someone says I didn't understand what he was talking about at the end of the last lecture when he was doing the Bohr model.

所以，有人会说，我不理解老师,在上节课末尾说的内容,当他在做玻尔模型的时候。

Now, what I want to do now, what I want to is, periodically in the class and we have a model up there and we've got to analyze it.

接下来,我想要做的事,定期地在课堂上,建立模型然后分析这个模型

That may make sense for some organizations, Certainly the open university in UK was founded on That as their basic model. But given MIT's course Strength and core abilities, we decided that what'll Make sense is to focus on two major things.

那对于一些机构是有意义的，比如英国的开放大学就,建立在这个基础模型上,而鉴于麻理优势和核心能力,我们决定要注重两件事。

So, what he did was kind of impose a quantum mechanical model, not a full one, just the idea that those energy levels were quantized on to the classical picture of an atom that has a discreet orbit.

还不是完整的,只是这些能级，是量子化的概念，作用到原子有分立轨道的经典原子模型上,当他做了一些计算后,他得到有个半径,他算出来。

So last time, we looked at Cournot.

上节课,我们讲了古诺模型

It says there is an equilibrium with only one candidate standing and that candidate would be the median candidate, just like it was in the model we saw on your homework assignment and also in class.

它是指一个候选人参选时只有一个均衡,且那个候选人是中间的候选人,就像在你们的家庭作业,和课堂上见到的模型一样

So, one thing we said last time was when we put up a model and try and draw lessons from it, we should just take a step back and say, what's missing here?

在上一讲,当我们,从一个模型中总结结论的时候,我们应该回过头重新审视一下,看看我们是不是疏漏了什么

So leaving aside the specific example of beer, you think about some product that has some dimension on which it varies, and we can use this model to see how competition is going to work in that market.

把啤酒的例子放在一边,你们自己想一些在某种程度上,有所不同的产品,我们使用这个模型来研究,这个市场的竞争是怎样的

Now remember that there were only four different colors in the cartoon of the DNA double helix that we talked about and I told you that those colors are really - represent the bases but there's five of them here.
