And, at the other extreme, we have elements with very high value, elements with high average valence electron energy.

另外，在另一端，我们有原子序数较大的元素，这些元素有着较高的平均化合价和电子能。

Because very often,if we only study the average, we only see the average,we only see the geometric shapes and completely missed the children on the bus.

因为很多时候，如果我们只研究平均水平，那就只会看到平均的结果，只看到几何形状,完全忽略了汽车上的孩子。

Back in the 1840s, life insurance was very important because the average expectancy of life was only something like forty-five years, so that meant parents were dying left and right.

在19世纪40年代的时候,寿险是非常重要的,因为当时的人均期望寿命,仅为45岁左右,这意味着双亲平均只能活到45岁

So, for example, we have this average level, and then it can go high where we have the peak, or it can go very low. We can also discuss sound waves, so again it's just the periodic variation of some property -- in this case we're talking about density, so we have high density areas and low density areas.

例如这是平均位置，在峰的位置水位高，在谷水位低，我们也可以,讨论声波它也是某种,量的周期变化，在这里我们,讨论的是密度,我们有高密度区和低密度区。

The number of calories you guys consume as a part of your diet, if you're the average person, is much higher than used to be the case and that has very interesting biological implications that we'll discuss.

从作为饮食一部分的饮料中摄取的热量,就普通人的情况而言,和过去相比要高得多,这包含了一层有趣的生物学含义

Good, so even if everyone in the number-- everyone in the room didn't choose randomly but they all chose a 100, a very unlikely circumstance, but even if everyone had chosen 100, the highest, the average, sorry, the highest two-thirds of the average could possibly be is 66 2/3, hence 67 would be a pretty good choice in that case.

好的,如果每个人,教室里的每个人不是随机选择数字,而是全选了100,这好像不太可能,但如果每个人真的都选了100,就是最大的书,那平均数,抱歉,平均数的2/3会是66又2/3,此情况下67应该是个不错的选项

In fact, there are some very old books that show this as the average, the sum divided by two arithmetic mean, but the modern practice is to use the geometric mean.

事实上，一些很老的书籍上,平均的定义就是算数意义的，总的来说被分为两种算数意义，但现代我们多用几何意义。
