Quite often, it's natural to pick x and y in a certain way, because starting a projectile near the Earth, it makes sense to pick the horizontal as x and vertical as y.

我们经常会很自然地选取 x 轴和 y 轴,因为如果在地表附近做抛物运动,我们通常以水平方向为 x 轴,竖直方向为 y 轴

These laws of nature, as he describes them, do not issue categorical commands so much as Y sort of hypothetical rules. If you want X, do Y; if you want peace, here are the means to it.

如霍布斯所述，这些自然法，不如假设的规则发布的绝对命令多,如果你想得到X，你就要去做;,如果你想要和平，这就是方法。

Let's create a graph here that on the x axis it's going to be time, so time zero will be when you first take in a food and then one hour later, two hours later will be shown as you go from left to right, and then we'll have blood glucose level up on the y axis.

我们在这建立一个曲线图,X轴代表的是时间,所以零时间点是你第一次进食的时间,然后一小时以后,两小时以后,是从左到右呈现在图表上的,在Y轴上是你的血糖值

OK, as I said, I want equality in the case of points to be, are the x- and y- coordinates the same?

好，正如我所说，我想要这个例子中的，点相等的意思是？

Y I'm not passing an x and I'm not passing a Y, &y I'm passing an ampersand x and ampersand y and can you take a guess as to what the ampersand operator must mean?

And I originally decided I was going to have as points, it's going to have internal values of an x and a y.

写了一堆代码,然后我以开始决定，是要把值放到点里面的,点有内部的x坐标和y坐标。

Well you know what a point is, it's got an x- and a y- coordinate, it's natural to think about those two things as belonging as a single entity.

把这两个坐标认为，是属于一个独立的实体，是理所当然的事情,因此实现这个目的的。

They might very well be storing the addresses of memory elsewhere, but we just needed them as sort of a cheat sheet, a little address card to know where the original values x and y were.

它们存储在内存的其他地方是可以的,但是我们需要一个备忘单,一个地址卡，来知道,原始的值x和y是什么。

So, you can see, it's much easier to describe that as one term, r here, instead of using both y and z.

所以，你们可以看到，用r而不是y和z来做描述，使得它变得更为简单。

I mentioned something of increasing importance only later, which is that you are free to pick another set of axes, not in the traditional x and y direction, but as an oblique direction.
