And en route we discovered that we can divide the Periodic Table into metals, 75% which is about 75% of the Periodic Table.

我们发现,我们能够将元素周期表划出金属，大概占。

So I'm first going to look for something that's not in the list, I'm going to see, is minus 1 in this list, so it's going to be at the far end, and if I do that in the basic case, bam.

如果我试试第一种最基本的方法,噢，一下就完成了对不对？,因为这种方法查了下第一个元素，然后发现目标数比较下，因为目标数小于第一个元素。

And he actually did this in the late 1800's, back before even all of the elements that we know today were discovered, really only about 60% or so, 70% were discovered then that we now know today.

他最终在十九世纪晚期完成了这一壮举，难能可贵的是,虽然我们现在已经发现了所有的元素，但在当时已知的元素只有我们现在知道,百分之六七十，在这种情况下。

It's as though I've walked across the stage like this realized, damn, it was the guy over here or rather I found the smallest element here who beat out number 2 over here so I can now put number 1 into place and recall that it didn't matte if I punted whoever was standing here 'cause they were given to me randomly anyway.

这就像是我这样走过讲台,然后才发现要找的人在那儿,或者说发现了最小的元素,那么就可以将1号放在正确的位置,而在这儿的是谁并不重要,因为他们本身就是,随机的。

他在论文中说，当时,我觉得发现更多,的元素的通用系统是很有用的,这就是我的计划。

A couple of other things about hydrogen: hydrogen also, like other elements, has isotopes and we already saw that in 1766, Cavendish isolated atomic hydrogen and enunciated some of its properties.
