So if we look at sulfur, what we need to do is take the valence electrons in sulfur, and there are 6.

因此如果我们来看硫原子的话，我们需要做的是,将硫的价电子，有六个。

So again if we look at this in terms of its physical interpretation or probability density, what we need to do is square the wave function.

如果我们从物理意义或者,概率密度的角度来看这个问题，我们需要把波函数平方。

What we need to do is get rid of the Coulomb tag that we have - that's how we measure our electron charges - charge, and so we use this epsilon nought quite often, this permativity constant of a vacuum to make that conversion.

怎么量度电子电荷,所以我们会经常用到,这个epsilon，nought记号,这是真空中的介电常数,我们还要指出,这个介电常数。

So, basically what he's saying here is we pretty much understand what's going on there's nothing new to really discover, all we need to do is measure things more precisely.

他的意思也就是说,我们对世界上的所有事情,都很了解了，没有什么新的东西尚待发现的,我们剩下要做的就是。
