I'm a planetary geologist here at the Air and Space Museum.

I'm asking about this thing that's extended obviously through space since car has taken up some space and through time.
我问的是这个贯穿,当然也贯穿空间,因为车子也占空间,还有贯穿时间的物体。
It will probably quit at some point because of space issues, unless I'm writing an algorithm that is using no additional space.
其中一个的时候,它会一直运行下去,它可能在某一处因为空间问题退出,除非我写了一个。
So first I'm gonna say something about identity across time or indeed initially identity across space with some familiar humdrum material objects.
所以我首先要,用一些大家熟悉的一般实物,谈谈贯穿时间,和贯穿空间中的人格。
And, now let's go back to, whoops, I'm running out of space.
再看回来,很高兴啊。
So, suppose I'm in a function, I need the space.
假使我在一个函数中,我需要一个空格。
what I'm talking about is a space, a safe space in our lives with our closest friends, with our family, first and foremost, with ourselves, will we have the permission to be human.
我的意思是一个空间,生活中的私密空间,和挚友一起时,和家人在一起时,最重要的是面对自己时,我们要准许自己为人。
Well I'm going to suggest that what I did was I really traded space for time. It makes me sound like an astro physicist somehow right?
困难在哪里?我在这里是如何权衡的?,我在这里所做的就是用空间换时间,这让我听起来像一个天体物理学家,是不是?
I'm going to clear some space here.
我先打出些空格。
The extended-through-space train that I'm picking out when I pointed the locomotive turns out to be a different train from the extended-through-space train I picked out when I pointed to the caboose.
当我指着火车头,所提到的贯穿空间的火车,和我指着火车尾,所提到的贯穿空间的火车,不是同一辆。
So, for example: in this case, my list is a bunch of integers. And one of the things I could take advantage of, is I'm only going to need a finite amount of space to represent an integer.
列表是一系列整数,要注意的这里的优势能够,用有限的空间来表示整数,例如,如果我想要操作。
That in many cases, I can gain efficiency if I'm willing to give up space. Having said that though, there may still be a problem, or there ought to be a problem that may be bugging you slightly, which is how do I guarantee that my hash function takes any input into exactly one spot in the storage space?
普遍存在的增益和权衡,在许多的例子中,可以通过牺牲空间而得到效率方面的增加,话说回来,仍然存在一个问题,或者应该会有一个问题困扰着你,就是我如何保证我的哈希函数能够准确将,任一输入映射到相应的唯一的存贮空间中去?
