Then they said, I'm going to ask you a question but before you answer the question I'm going to spin a wheel of fortune.
他们说,接下来我要问一个问题,但是在你们回答之前,我会转幸运轮盘
-
What they did it--they said, we'll ask you the question and think about it, but while you're thinking about it--don't answer yet -we're going to spin this wheel of fortune.
实验是怎么进行的呢,他们说,我们会问你们问题,考虑一下,先不要回答,我们会转这个幸运轮盘

And this spin magnetic quantum number we abbreviate as m sub s, so that's to differentiate from m sub l.
这个自旋磁量子数我们把它简写成ｍ下标ｓ,以和ｍ小标ｌ有所区分。
-
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。
-
As soon as I detect with what we'll call a condition if I'm touching the edge I have to essentially spin around 180 degrees and then continue looping.
一旦我检测到这种情况,当我碰到边界时,我需要转180°然后继续这一循环过程。
-
We're going to be reading it with a theoretical spin.
我们将带着一种理论的倾向性来阅读本周的内容。
-
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。
-
/2 You can have it equal to plus 1/2, and that's what we call spin up, 1/2 or you can have it equal to minus 1/2, which is what we call spin down.
它可能会等于，我们叫它自选朝上，或者它等于负，我们叫它自旋朝下。
-
And that the fact that it split into two was telling them that there must be some new property to the electron, and what we call that now is either being spin up or spin down.
它能一分为二的,事实告诉我们,电子一定有某种新的性质，我们叫它自旋向上或者自旋向下。
-
So what that means is that we're limited in any atom to having two electrons per orbital, right, because for any orbital we can either have a spin up electron, a spin down electron, or both.
这意味着在一个原子内,每个轨道上可以有两个电子，对吧，因为对任何轨道,我们可以有自旋向上或者自选向下或者两者都有。
-
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。
-
One way to think about it, if we want to use a classical analogy, which often helps to give us an idea of what's going on, is the spin of an electron, we can picture it rotating on its own axis.
如果我们用一个，经典的比喻来考虑它的话，这经常会帮助我们建立起一些概念，就是我们可以把电子的，自旋想象是它绕着轴自转。
-
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。
