"Just a back-of-the-envelope calculation shows that in the Philippines, if we in a year can be reaching just five thousand farmers and their fields can be increasing the yield by half a ton per hectare, we could be looking at profitabilities for those farmers in the range of half a million dollars."

And then, if you go the real sodium chloride crystal and you do this same calculation but in three-dimensions.

接下来，如果回到实际的氯化钠晶体中,你们做同样的计算,但是是在三维中。

However, if there are repeated, unexcused absences, there will be an adjustment in the grade calculation, and it will be worth twenty to twenty-five percent of your grade, and it will be a negative grade also.

然而，如果有反复的没有理由的缺勤，就会对这个百分比做些调整，出勤率就会占到你分数的百分之二十到二十五，当然也会是负面的评分。

But the beauty in this calculation is it shows that this concept of electron sharing in an unequal manner is sound and it gets you into the right ballpark.

但在这个计算过程中,真正漂亮的是对电子,非平均共价的考虑很完全,从而指引我们向一个正确的方向思考。

In fact, it's interesting to note that the first calculation on the impact of CO2 on climate was done in the late 1800's by Arrhenius.

很有趣地,是阿列纽斯在19世纪末,第一个做了的关于二氧化碳,对气候的影响的计算。

And if we do that calculation, what we find out is that the binding energy, in this case where we have no shielding, 72× is negative 8 . 7 2 times 10 to So, let's compare what we've just seen as our two extremes.

我们会发现结合，能在这个情况中，没有屏蔽，等于-8。,所以我们来对比一下,我们在两个极端的案例中看到了什么。

He goes back and redoes the calculation, only in this case he says what I am going to do is I am going to redo the calculation for helium, but I am going to consider not just the mass of the electron but the reduced mass of the system.

他回去重新做了计算，仅在这种情况下他才会说说我将要,为氦重做计算，但我认为,不只是电子的质量,还有系统质量的减少量。

So that you take every sodium and you count all of its nearest neighbors, next nearest neighbors, next next nearest neighbors, not only on a line but in the plane and above and below in all three dimensions and go through that calculation, it is even more negative.

你考虑到每一个钠原子,你要考虑到它最近的原子，第二近的原子，第三近的原子，不是在一条线而是在一个面上,以及面上与面下的三维空间,再完成计算，这将会更负。
