And some of them might be spinning clockwise, in which case, according to the right-hand rule we would consider them spin-down.
而另一些电子则是在顺时针自旋，在这种情况下，根据右手定理,我们会以为它是在向下转。
-
In contrast, if we're taking the wave function and describing it in terms of n, l, m sub l, and now also, the spin, what are we describing here?
相反，如果我们考虑一个波函数,然后用ｎ，ｌ，ｍ小标ｌ,还有自旋，我们描述的是什么？
-
You do that eight billion times in your life and you can hit a good top spin backhand.
如果你把这个动作做上八十亿次,那你一定能打个漂亮的反手上旋球
-
And, in any arbitrary crucible full of molten silver, half of them are going to be spin-up and half of them are going to be spin-down.
并且，在任一个浇满了熔银的坩埚中，银原子中的电子一半是向上转,另一半是向下转。
-
To say it's natural for us to do so is not to say we engage in political life spontaneously and avidly, as you might say spiders spin webs or ants build anthills.
说我们本能地会那么做,并不代表,我们自然且贪婪地,忙于政治生活，就像蜘蛛结网,或蚂蚁筑蚁冢。
-
And this spin is an intrinsic quality of the electron, it's a property that is intrinsic in all particles, just like we would say mass is intrinsic or charge is intrinsic.
自旋是电子的本征量，它是所有粒子的本征性质，就像我们说质量是本征的或者电荷是本征的。
-
When we have just a single bond in them molecule, you have all the free rotation you want, you can just spin it around, there's nothing keeping it in place.
当我们在分子力只有一个单键时，你可以随意旋转，你可以让它转起来，没有什么东西能固定住它。
-
I put in the first one spin-up.
首先放入一个自旋向上的。
-
So you can see, if it's spinning on its own axis in this direction we'd call it spin up, where as this way it would be what we call spin down.
你们可以看到，如果它绕自己的轴朝这个方向转,我们就说它是自旋朝上，这个方向我们叫它自旋朝下。
-
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。
