So I think that is one of those place where nature and the notion of God come together.
我想应该有一个点,自然和上帝这两个概念在这点汇合。
So we have system insulated from the outside world, and we have two bulbs.
我们有一个与环境隔绝的系统,和两个腔体。
So in terms of the first step of skeletal structure, this is actually going to be easier because we don't have a central atom, we just have carbon and nitrogen here.
对于第一步画出骨架,其实比刚才更容易,因为我们没有一个中心原子,我们这里只有碳和氮两个原子。
I've got one test there, and then I've just got one thing to do here, which has got a subtraction and a multiplication.
这儿有一个比较,然后在一个基本步骤里,做了一个减法和一个乘法两个基本操作。
I've set these two things equal to each other: I've got one equation and one unknown.
我让两个方程相等,只剩下了一个等式和一个未知数
He was trying to describe electrons, but the theory said there are two roots in the quadratic equation and the second root is mathematically as interesting as the first one.
他当时只是想去描述电子,但是数学理论告诉我们,二次方程有两个根,而第二个根在数学上和第一个根一样有趣
They put together a documentary, and in one of the scenes it's a camp place called Drancie, which is out near the airport, halfway to the airport, to Roissy Airport.
有人把两个和起来做了个纪录片,有个镜头是在一个集中营叫德朗西,在机场附近,不到机场,戴高乐机场
And actually, if I don't want to clobber, as we say, overwrite the value of my variable, ; I could declare another one and store the return value in Y; Y so now I have two ints in memory; X and Y, 3 one with two, one with three.
实际上,如果你不想彻底清除,像我们说的,覆盖那个变量的值,我可以申明另一个变量Y,并在Y中保存那个返回值;,现在内存中有两个int数,X和,一个的值为2,一个为。
OK, notice we have two inexact differentials and exact differentials. This is a condition.
好,注意到这里面有两个不准确微分量,和一个准确微分量,这是结论。
So let's take the case of acetylene where we have two carbon atoms that are going to be triple bonded to each other, each are bonded to a carbon and then to one hydrogen.
让我们来看一看乙炔的例子,我们有两个碳原子,成三键,每个碳和一个碳一个氢相连。
So what we're going to do is take the equations for those two lines, so here's one of those equations and here's the other one, set the P in those equations equal to X, I've got two equations in one unknown, I'm sorry, I've got one equation and one unknown.
接下来我们只需要,列出这两条线各自的方程,也就是这个方程和这个方程,把方程中的P换成X,我就得到了两个等式和一个未知数,错了,是一个等式和一个未知数
