So, Marsden came up with the model, and as you go through 8.02 and you understand electrostatics and electrodynamics, you'll be able to do this analysis.
后来马斯登提出了这个模型,就像你们通过8。02的考试一样2,你们学过了静电学和电动力学,你也能做这些分析。

So, I said I'd tell you a little bit more about where this Bohr radius came from, and it came from a model of the atom that pre-dated quantum mechanics, and Neils Bohr is who came up with the idea of the Bohr radius, and here is hanging out with Einstein, he had pretty good company that he kept.
我要告诉你们,波尔半径是从哪里来的,它起源于前量子力学时代的,原子模型,尼尔斯,玻尔提出了,波尔半径的概念,这是他和爱因斯坦在一起,他们是好朋友,当我们讨论这个原子模型时你们要记住的是,在1911年。
This is by the famous biologist, D'Arcy Thompson, who wrote the book On Growth and Form, and it's sort of the model of many developmental psychologists and many evolutionary psychologists so I'll end with this: "Everything is the way it is because it got that way."

但依健康模式来看,这是不够的;,让我们超越那种程度。
The model might not apply with more than two candidates.
此模型可能不适用于两个以上的候选人
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
Now here we ended up with two centrist candidates, which is a result pretty close to what we saw in the Hoteling model, Is this an equilibrium?
现在我们最终有2个中间派候选人参选,这与我们,在霍特林模型中看到的非常相似,这是一个均衡吗
It was the model we started with.
就是我们在一开始学习的模型

和布丁模型是吻合的,所有的重alpha粒子,都穿过金原子,你们也许会觉得,他可以就此。
So, Thomson came up with a model for the atom due to this, and this is called the Plum Pudding model of the atom, and he was, as we said, English, so plum pudding is kind of a British food.
所以Thompson因此,想到了一个原子模型,他把它叫做,李子布丁模型,我们说过他是英国人。
So you recognize patterns and then develop a model, and most desirably a quantitative model A quantitative model that explains the observations, obviously.But what Mendeleev did was he came up with a model that not only explained what we observed.
所以你们得到这些模式,发展成一个模型,和最令人向往的定量模型,一个定量模型明显地解释所有的观察结果,但是门捷列夫做的是,他提出的模型不仅解释了,我们观察到的东西。
