So, it's Newtonian mechanics, and the reason for this is because Newtonian mechanics does not work on this very, very small size scale.

牛顿力学，因为牛顿力学,在这种很小的尺度下不适用,我们说过，牛顿力学。

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。

You have extensive properties and intensive properties The extensive properties are the ones that scale with the size of the system.

广延量,和强度量,广延量的值,随着系统的规模变化。

So, then we'll get to turn to a new kind of mechanics or quantum mechanics, which will in fact be able to describe what's happening on this very, very small size scale -- so on the atomic size scale on the order of nanometers or angstroms, very small particles.

然后我们要讲到一种,新的力学--量子力学,它可以解释,发生在很小尺度,大约是原子尺寸大小,也就是纳米或埃的量级。
