And the way that we'll do this is starting with talking about the discovery of the electron and the nucleus here.
在这之后,我们就可以通过,经典力学来描述一个原子。
-
So, what we can do is try using the classical description of the atom and see where this takes us.
用经典力学描述原子看看怎么样,我们要考虑的是一个,带正电的粒子和。
-
And I'm no scientist and I'm no specialist in sort of empirical matters, and believe me, I'm no authority on quantum mechanics, our best theory of fundamental physics.
我不是科学家,也不是实证方面的专家,相信我,关于量子力学,我并没有发言权,那可是基础物理中最经典的理论
-
And today we'll finish that discussion, and, of course, point out actually the failure of classical mechanics to appropriately describe what's going on in an atom.
结束这部分的讨论，当然的，要指出经典力学,在描述原子内部,情况时是失败的。
-
Also, when we're looking at the Schrodinger equation, it allows us to explain a stable hydrogen atom, which is something that classical mechanics did not allow us to do.
当我们看一个薛定谔方程的时候，它给出一个稳定的氢原子,这是在经典力学中做不到的。
-
And, as I mentioned, we left off and as we started back here to describe the atom and how the atom holds together the nucleus and the electron using classical mechanics.
我之前提及过，我们上次,讲到应用经典力学如何描述,一个原子以及原子如何把质子,和电子束缚在一起，今天我们要。
-
That's a deterministic way of doing things, that's what you get from classical mechanics.
与核子的半径,是从经典力学中得到的，但我们从量子力学模型，知道的事实是。
-
There's no classical way to think about what a wave function is.
我们没有办法从经典力学的角度,想象波函数是什么样的，没有经典的类比。
-
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。
