All right. Now the hermeneutic circle, then, involves this reference back and forth between the entities that I've been trying to describe.

好，现在我们知道解释学循环，包括在我刚刚所说的,存在之间的穿梭。

So let's look at a couple of passages from your sheet, from Heidegger's Being and Time, from his analytic of the hermeneutic circle, and see what Heidegger has to say about this claim.

所以我们看几篇文章，摘自海德格尔的存在与时间，从他对于解释学循环的分析，看看海德格尔对这个观点看法是何。

When a particle moves in a circle, it has an acceleration towards the center of this size, v^2 over R.

当一个质点在圆周上运动时,它有一个指向圆心的加速度,v^2 / R

We know it's going around in a circle because if I find the length of this vector, which is the x-square part, plus the y-square part, I just get r square at all times, because sine square plus cosine square is one.

我们之所以知道它做圆周运动,是因为我求出了这个矢量的模长,也就是 x 的平方加上 y 的平方,我就得到了它在任意时刻的模长平方,因为正弦平方加余弦平方始终等于1
