If I gave you the location of a particle as a function of time, you can find the velocity by taking derivatives.

如果我给出物体的位移是时间的函数,你可以通过求导来得到速度

The work is not, in a sense, written simply as a sort of timeless philosophical treatise, but as a dramatic dialogue with a setting, a cast of characters and a firm location in time and place.

但本书的著作目的，不仅是,永恒的的哲学论述，更是戏剧性的对话，内含场景，人物,及一个确切时间与位置。

Well, if that's right, then should we say that the pervasiveness of death, ubiquitousness of death-- the thing that I was earlier suggesting was oppressive-- wouldn't it really be nice to have a death-free time or a death-free location or death-free activities?

如果是这样的话，那我们是不是应该说死亡的普遍性，死亡的无处不在性-,这些我之前所说的特征是不对的-,如果有死亡免疫时间或者死亡免疫地点,或者死亡免疫活动岂不是很好吗？

To get any location in memory, to get to any value of the list, I simply have to say which element do I want to get, I know that these things are stored in a particular size multiply that index by 4, add it to start, and then it's in a constant amount of time I can go to that location and get out the cell.

取得列表中的任何一个值,简单说来，想要取得列表中的任何元素,我知道这些元素存在特定的大小中,把下标乘以4，加到start上,然后定位到内存单元，并取出值就是固定的时间了,好的，如果元素以固定大小存储。

The answer was: at any time t, the location of the particle is given by this formula.

答案是,在任意时刻 t,这个质点的位移都由这个式子给出

Then for any time t, you plug in the time t and you will get the location.

那么在任何时刻 t,当你代入 t 的值,就可以确定位移

if I say a particle's location is i times t^2 plus j times 9t^3, for every value of time, you can put the numbers in and you can find the velocity by just taking derivatives.

一个质点的位置,i ? t^2 + j ? 9t^3,在每一个时间点,你可以把数值代入,并通过求导得到速度
