This is important because we use this all the time for when, when we do technology.

因为当我们做技术工作,的时我们一直在用它。

You use it all the time, but maybe along one dimension.

你也许在一维空间里一直在用它

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。

So it's really neat to think that your counterparts 100 years ago right here at MIT could have been sitting in a class where they had Lewis as their lecturer, and he's putting forth these ideas -- these are actually his lecture notes, even though it wasn't even published yet, and giving this idea of Lewis structure, which is exactly what we keep using today in order to make a lot of these predictions.

因此会有很棒的感觉，当想一想一百年以前像你们一样,在这上学的同学可能正坐在教室里,听路易斯讲课，而他正在提出这些想法-,-而这些正是他的课堂讲义，尽管当时还没有发表，但已经给出了路易斯结构的思想，这正是我们直到今天都一直在用的,用它来做很多预测。
