But once we got to the atomic size scale, what happens is we need to be taking into account the fact that matter has these wave-like properties, and we'll learn more about that later, but essentially classical mechanics does not take that into account at all.

但一到到了原子尺度量级，我们必须考虑到物质,这时候有波动性质,关于这点我们今后将会学到更多,但本质上经典力学并,没有考虑这个性质。

And the reason that quantum mechanics is going to work where classical mechanics fails is that classical mechanics did not take into account the fact that matter has both wave-like and particle-like properties, and light has both wave-like and particle-like properties.

上发生的行为,量子力学得以成功,而经典力学却失败的原因,是因为经典力学,不能包容物质的，波动性和粒子性,和光的波动性和粒子性。
