But it is interesting. Let's just, for an order of magnitude say what happens for ground state electron in atomic hydrogen?

但行星模型其实挺有趣的，按照重要的先后顺序，我们来猜想一下,氢原子中的基态电子会发生些什么？

Then the acceleration of the planet is the force of gravity between the planet and the Sun, which Newton will tell you is directed towards the Sun and it depends on how far you are.

That was Cartesian space. When I plot r as a distance out from the nucleus that is sort of our simple-minded planetary model. Now let's look at energy.

笛卡尔坐标系，当我用r表示,离原子核的距离时，那只是我们头脑中简单的,类似行星的模型，现在我们看一下能量问题。
