But you can also look at it qualitatively, so, if you think about the force between the electron and the proton, you could just qualitatively think about what's happening.

但你也可以定性的来研究这个问题，所以如果你们考虑电子,和质子之间的作用力,你可以定性的来想。

So, let's think qualitatively for a second about what that means or what the real meaning of that is. What that is telling us is that according to Newtonian mechanics and Coulomb's force law, is that the electron should actually plummet into the nucleus in 0.1 nanoseconds.

让我们定性的想想,这意味着什么,这告诉我们,根据牛顿力学,和库仑定律，电子,在0。1纳秒内,就会掉到原子核里面。
