1/2 And we have the spin quantum number 2 as plus 1/2 for electron one, -1/2 and minus 1/2 for the electron two.

我们有自旋量子数,对于电子，我们有自旋量子数。

But now, it has come to light that they are the ones that do get credit for first really coming up with this idea of a spin quantum number, and it's interesting to think about how the politics work in different discoveries, as well as the discoveries themselves.

但现在我们,知道他们是,最先想出自旋量子数,这个概念的人，看各种发现中的,政治学是十分有趣的，和发现本身一样有趣。
