And by the time I'm a million, I no longer remember what I was doing when I was a lad of 500,000.
等我活到一百万年,我不记得,50万年前做过什么。
So, saying wave functions within molecules might sound a little confusing, but remember we spent a lot of time talking about wave functions within atoms, and we know how to describe that, we know that a wave function just means an atomic orbital.
说分子内的波函数可能,听着有点容易搞混,但记住我们花了很多时间,讨论了原子中的波函数,而且我们知道如何去描述它,我们知道波函数意味着原子轨道。
Remember last time, I said that there's different kinds of complexity in our code, and I suggested for simple branching programs, the amount of time it takes to run that program is, in essence, bounded by the number of instructions, because you only execute each instruction at most once.
但是这里有个很重要的点,记得上节课,我提过在我们的代码中,有不同种类的复杂度,而且我还说了对于简单的分支程序,运行这种程序需要的总体时间,大体上,是和指令的数目相关的,因为每个指令只会被执行最多一次。
But cutting is something fearful and forceful; it's a kind of controlled violence. Frost takes it for granted that we will remember that the scythe is a conventional image for time, which harvests all of us in death.
但是割草是很有力的也是很可怕的;,这是一种控制中的蛮力,弗罗斯特认为,我们将把镰刀作为时代的产物记住,镰刀一直收获直到我们死去。
Now, remember we talked about these last time, voltage-gated channels are channels that would allow the passage of sodium, in this case, but they can exist in two states, a closed state and an open state.
还记得我们上节课讨论过的吧,电压门控通道是,一种可以容许钠离子通过的通道,在这一例子中 电压门控通道有两种状态,关闭状态和开放状态
Remember I talk those of you who were here the first time: this course is built like a spiral Everything is intra-connected, what I talked about in the first class is connected to what I'm going to talk about today, is going to be connected to lecture 19.
记得一开始我就跟你们说过:,这课程就像个螺旋,内部的一切都是相关的,第一节课讲到的内容,与今天要谈的课题有关,也和第19课有关。
So, you remember from last time radial nodes are values of r at which the wave function and wave function squared are zero, so the difference is now we're just talking about the angular part of the wave function.
你们记得上次说径向节点在,波函数和波函数的平方,等于零的r的处,现在的区别是我们讨论的是,角向波函数。
Remember last time, we wrote this simple piece of code to print out even or odd. If, you know, x, 1 it was in fact, even or odd. So let me show you what a flow chart for that would look like, because I want to make a comparison point here.
这就像这里有一些脚蹼一样,首先进行测试,然后把球这样放来让ANS加,然后回来继续测试,最终跳出循环然后打印答案。
Remember last time, we wrote this simple piece of code to print out even or odd. If, you know, x, it was in fact, even or odd. So let me show you what a flow chart for that would look like, because I want to make a comparison point here.
记得上节课我们写过的,那个显示奇数还是偶数的程序么,如果,你知道,x,实际上是奇数还是偶数,那么让我来为大家画个这个程序的流程图吧,因为我这里想为大家做个比较。
