And what is plotted below is the actual wave function, so you can see it starts very high and then the decays down.

下面这画的是，波函数，你们可以看见它开始非常高,然后衰减下来。

It's very relaxing, it achieves the same function as focusing on your breath, give you something not to get lost, but feel sort of centered in.

它令人十分放松，它能和集中注意力呼吸,起到同样的作用，并不是让你迷失，而是感觉到集中起来。

One way to think about this intuitively if the derivative is very large the function is changing quickly, and therefore we want to take small steps.

关于这个方法很直观的一点想法是,如果导数非常大,函数也就变化的非常快，因此我们想一小步一小步的来。

This is a discontinuous payoff function, so differentiating isn't going to get you very far.

这是一个不连续的收益函数,所以不会涉及太多微分的东西

But they also serve another very important function, and that was the formation and maintenance of a differentiated ethnic identity or in Priestly parlance, the formation and maintenance of a holy peoples separated out from other nations by rules that mark her as God's people.

但是它们也有另外一个很重要的功能，这个功能形成并维护了,一个分化的种族身份，或者用神职人员的说法，这些规则促使了神圣民族的形成和保持,这个民族和其他的城邦区别开来，被标记为上帝的子民。

So, conceptually if you've ever wondered why you get access in all of your functions to global variables that's because they're not down here, they're at the very top of RAM and any function can access that RAM way up there, but for now the interesting player in the story is this thing called the heap.

所以，如果你想知道为什么全局变量能在,所有的函数中使用,那是因为它们不在这下面，而是在内存的顶端,那样任意函数都可以在内存中使用它们，现在，这里面一个有用的角色是,叫做堆的东西。

It turns out we can express all these functions in terms of G, G we wouldn't need to choose G, but it's a very useful function to choose.

最终我们能把所有的这些函数,用自由焓G表示出来，我们没有必要选择，但是这个选择很有用。

It's very clear I've got to start with a function that looks like t^.

显然,我得从一个类似与t^的函数开始

So, what we can do to actually get a probability instead of a probability density that we're talking about is to take the wave function squared, which we know is probability density, and multiply it by the volume of that very, very thin spherical shell that we're talking about at distance r.

我们能得到一个概率,而不是概率密度的方法,就是取波函数的平方，也就是概率密度，然后把它乘以一个在ｒ处的,非常非常小的,壳层体积。

In terms of function they're very important because this stem cell which is produced goes back into the population of stem cells and is able to repeat this process to form new committed progenitor cells and to form new stem cells.

但就功能而言这些干细胞则至关重要,因为这类分裂产生的子细胞,依然是干细胞,可以再次重复上述步骤,生成新的定向祖细胞,和新的干细胞

So again, if we think of a graph of the wave function, we had the wave function is at its highest amplitude when it's lined up with the nucleus, and then as we got further away from the nucleus, the amplitude of the wave function ends up tapering off until it never hits zero exactly, but it goes down very low.

同样，如果我们想象一幅波函数的图，波函数在原子核的位置上,有着最高的振幅，随着与原子核距离变远，波函数振幅逐渐变小直到,它永远不会到零，但它会变得很小。

As time goes on, we've developed ever more complex machines to study people and we've talked about some of these already: EKG machines, so an example of an electrical device that can be used to monitor a very elaborate function deep inside your body, the beating of your heart and the rhythm of your heart.

如今,我们已经有功能更加复杂的设备,来研究人类,比如之前说到的心电图,我们使用电子装置,对身体内部机能进行精确地监控,具体到心电图就是心跳和心率

So we hit the curly brace so the very bottom of the function and as soon as you hit that, the next line in the story is well, then we return to main and where are we executing in main?

我们抵达花括号了，这是函数的末尾了,一旦到了那个地方，在下一行，然后返回到main函数中，在main中哪里开始执行？

In C, the truly correct way is to be very pathantic and say, ; nothing is coming into this function; void so I'll explicitly say, void here.

在C语言中，正确的方法是说明，没有任何东西进入到这个函数中来;,所以我明确地在这里指明。

So, if we look at the bottom here and the actual plot of the wave function, we see it starts high, very positive, 0 and it goes down 0 and it eventually hits zero, and goes through zero 0 and then becomes negative 0 and then never quite hits zero again, although it approaches zero.

我们看,这下面这是波函数，我们看到它开始很高，是正的，然后降低直到,然后它穿过，变成负的,最后接近,但没达到，在这个。
