将四象限和八象限推广到任意维数是正交的。

The generalization of the quadrant and octant to arbitrary number of dimensions is the orthant.

他说，八元数是否能对这现实世界做了什么事情，也仍然只是人们的猜测罢了。

"Whether octonions have anything to do with the real world is still anybody's guess," he says.

与她们监督的很多男性不同，华尔街的新长官们从未渴望获得八位数的补偿方案或企业套房。

Unlike many of the men they oversee, the new sheriffs of Wall Street never aspired to eight-figure compensation packages or corporate suites.

So, if you look at all of these, we have full octets for all of them, and if we count up all of the valence electrons, it's going to be equal to our number 26 here.

那么，如果大家看看所有的这些，它们的“八隅体“都填满了，而如果我们来数一数价电子的总个数，它应该就等于我们这里的二十六。

And also I wanted to mention in terms of checking your Lewis structures, regardless of what they are, you should always go back and I had 10, and then count 2, 4, 6, 8, 10, because you always need to make sure you have the same number of valence electrons that you calculated in your actual structure.

我还想提一点关于检查,你的路易斯结构的建议，不管它们是什么，你总是应该回去检查一下,我有十个，然后数一数，二，四，六，八，十个，因为你总是需要确保实际价电子的数量,与你在结构中算出的数量相等。
