All matter contains within it something like a "potency of life"; that's Milton's phrase. It has a capacity for action, actually a capacity for motion, and, just as books can take on a life of their own in Areopagitica, so all matter for later Milton.
所有物质都更包含一种类似“生命的潜质“的东西;,这是弥尔顿的原话，所有物质都有行动的可能,运动的可能，正如《论出版自由》中书籍可以有自己的,生命一样，晚年的弥尔顿相信一切物质都是这样。

and we have one for motion pictures.
还有给电影的。

What he did was took de Broglie motion of the electron as a wave and developed a wave equation for such matter waves.
他所做的就是,用电子的德布罗意运动,作为波并且对于那种物质波,给出波动方程。
-
But luckily for us, there's a classical equation of motion that will, in fact, describe how the electron and nucleus change position or change their radius as a function of time.
但幸运的是，有一个,经典方程描述了电子和核子,位置或者它们直接的距离是,如何随时间变化的。

So, for example, if you were trying to study the motion of some object, here is one example.
举个例子,如果你想研究某个物体的运动,这里有个例子

And,you may or may not be intested in the motion, as I am, but you might say: what is the signal good for?
对于情感来说，你们或许有兴趣，也有可能和我一样觉得没意思，但你会问，这种信号什么用处？

Yeah. I'm trying to be a film director, movie director for major motion pictures.
我在努力成为一名电影导演，一名动画电影导演。

Except for electromagnetism, the basics of mechanics, which is the motion of Billiard balls and trucks and marbles and whatnot, was set up by Newton.
除电磁学外,力学的基础,也就是台球,卡车,弹球以及其它小玩意儿的运动原理,都是由牛顿建立起来的

People to this day are looking for a theory of everything. And there is something very appealing about the notion that the rules that govern the motion of heavenly bodies might be applicable down at atomic dimensions.
现在人们总想寻求一些,可以阐明一切的理论,而这里正好有一些,可以吸引这种想法的东西,即支配天体运动的规则,可能对原子的尺寸也是适用的。
-
For example, suppose you use vertical motion and you use y instead of x; and a would be g or -g; that's a particle falling down under the affect of gravity.
例如,假设在竖直运动中,你用 y 来代替 x,那么 a 就是 g 或者 -g,这就是一个受重力作用下落的质点
