I am talking at the level of this is Dalton's model, but then there is a meta knowledge here of how you develop models in general.

So you start with your basic model, then you add in, you enrich the model, and you see if the results change, and that'll help you explain why you're getting different results in different settings.
你们从最原始的模型开始,加入约束条件来丰富这个模型,然后检验结果是否有变,这能帮助我们解释,为什么在不同条件下结果是不同的

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。
What I want this class to be is a class where at least sometimes, like on this homework assignment, I set up a model for you, set up the story for you, and then you have to actually figure out how do I set this up properly and how do I solve it out?
