So, we need a new kind of mechanics, which is quantum mechanics, which will accurately explain the behavior of molecules on this small scale.

所以我们需要一种新的力学，也就是量子力学,来解释在这个,小尺度下分子的行为。

Right, the first skill we want you to acquire, is we want you to be able to use the basic tools of computational thinking to write small scale programs.

好，我想让你们掌握的第一个技能就是，希望你们能使用,计算思维的基本工具,来编写小规模的程序。

but probably more at a small scale.

但是在比较小规模上。

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。

Being a very small part of that, and part of changing our scale from where we constantly see ourselves as the most important thing in the universe, to suddenly being just a tiny piece.

我们只是宇宙的渺小的一员，我们应当改变我们的观念,不应将自己看做是,宇宙中最重要的，我们只是微小的尘埃。

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。
