And then you might raise all sorts of questions about, well, was this part of God's plan that they ought to know this and should know this, so that their choice for good actually becomes meaningful.

你们也许会有很多疑惑，好，这是不是上帝的计划，人类理应知道这点,他们应该知道这点，那样他们择善也就变得有意义了。

And it should make sense where we got this from, because we know that the binding energy, if we're talking about a hydrogen atom, what is the binding energy equal to?

很容易理解，我们怎么得到这个的，因为我们知道，结合能，如果，对氢原子来说，结合能等于什么？

If we all have a desire to know, ? doesn't this connote something universal, that all should be free, that all should participate in ruling and being ruled as citizens of a city?

如果我们都有求知欲，这不就意味着一种普遍性吗，即所有的人都应是自由人，所有的公民应参与城市中的统治,与被统治的活动？

So this should immediately look like a problem because we know, in fact, that methane is tetravalent, and this is telling us it's only divalent.

显然这看起来是一个问题,因为我们知道实际上，甲烷是四价的，而这告诉我们它仅仅是二价的。

And what they could come up with, what they reasoned, is that there must be some intrinsic property within the electron, because we know that this describes the complete energy of the orbital should give us one single frequency.

他们想到着一定和，电子的本征性质有关，因为我们知道这个轨道的,完整描述会给出单一的频率。

This intuitively should make a lot of sense, because we know we're trying to minimize electron repulsions to keep things in as low an energy state as possible, so it makes sense that we would put one electron in each orbital first before we double up in any orbital.

这个直观上讲得通，因为我们知道尝试去最小化电子排斥力,从而尽可能的保持处于一个较低的能态,所以它讲得通,在我们在同一个轨道放入两个电子之前,我们首先把电子放入每一个轨道。

This should make a lot of sense, because we know that a hydrogen has 1 s as it's outer-most or valence orbital, so it can be filled up just with two 1 s electrons.

这也是很合理的，因为我们,知道氢只有，1，s，轨道,这就是它最外层的轨道或者说价轨道，因此只要两个，1，s，电子就可以将它填满。

So, we know in this example the initial height should be 15 meters and the initial velocity should be 10, and for acceleration, I'm going to use -g and to keep life simple, I'm going to call it -10.

我们知道在这个例子中,初始高度为15米,初始速度为10,然后是加速度,我们用"-g"表示重力加速度,为了计算方便,加速度的值取为-10
