So we ask very limited questions, which is why we brag about how accurately we can predict the future.

我们研究的问题是非常有限的,正因如此我们才敢自豪地说,我们能非常精确地预测未来

And the reason that we use it is that it is incredibly accurate, and allows us to very, very quickly predict and to predict accurately, in most cases, what the electron configuration of molecules are going to be.

我们用它是因为它极为精确，并且能让我们非常非常快地预测,而且是准确地预测，大多数情况下，分子应该具有的电子排布。

And Montmartre, and that's where their collective memory of the "forces of order," as they liked to call it, was very, very precise, and that's where they went in and massacred them.

还有蒙马特高地,在那里非常精确的留下了,关于他们称之为"治安部队"的共同记忆,这些就是他们冲过去进行屠杀的地方

Then also a problem is you can't weigh things when you're eating out, so even if you were being incredibly precise about stuff at home and you were actually weighing things, you couldn't do that very well when you're eating out.

问题是,当你在外吃饭时无法称量食物,所以即使你在家中非常精确地测量食物,并且实际测量了每样物品,但在外吃饭时你可没法这样干

So that means that we don't have to worry about things like wave functions when we're talking about Lewis structures, but because they're so simple to use and because they so often predict the electron configuration of molecules accurately, we end up using them all the time in chemistry, so it's very valuable to know how to draw them correctly and to know how to work with them.

因此这也就意味着我们在讨论路易斯结构的时候,不需要担心波函数之类的东西，但是由于路易斯结构不仅简单易用,而且用它来预测分子的电子排布,经常可以得到非常精确的结果，结果我们在化学中一直都在用它，因此知道如何正确地画出并运用,路易斯结构是非常有价值的。
