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.

But because you only have a finite number of bits, the takeaway for today is that there's only so much precision.
因为只有有限个比特,今天的重点就是,它就这么点精度。
So finite number of times can you specify with a condition, as we'll see in a moment.
所以你们可以指定一个条件来表示有穷的次数,我们等下将看到。
There's a finite number of notes but a limitless number of musical compositions.
音符的数量是有限的,但乐曲的数量却是无限的
That kind of problem tends to arise because they're using a language or a computer that only has finite precision and so there are rounding errors.
这类问题已经日趋严重了,由于他们使用的语言或电脑,都是精度有限的,因此存在这样的问题。
Of course, you have allowed it to move a finite distance in a finite time.
你是让它在有限的时间内移动有限的距离

语言使用的可能声音列表是有限的
Right. There's only a finite amount of memory.
对的,这里内存是有限的。
It's perfectly fine, but they envy us for our finite lifespans, because what we've got and they don't have is something that's for each individual rare-- something that's not lasting, something that's precious in that way.
不朽很好,但他们羡慕我们的有限寿命,因为我们有而他们没有的是,对每个人来说稀有的东西-,不会永远持久的东西,从那个层面讲珍贵的东西。
Your vocabulary is finite.
你的词汇量是有限的
Because you can come up with an infinite number of values but if you have a finite amount of space and certainly a computer has a finite amount of disk space or RAM, you have to make approximations.
你可能会碰到一些无限的值,如果你只有有限的空间,废话,电脑当然只有一个有限的磁盘空间,或RAM,我们得做一些近似处理。
So unlike Scratch where you pretty much had to say "repeat" ten times or whatever, or forever where it's just "forever" with for loops, -- can you actually specify a finite number of iterations -- and as I learned 15 years ago, finite is important.
所以不像Scratch,你大致上需要用,“repeat“10次或更多,或者需要不断地使用当它,是死循环时,你们能够指定出一个有限的迭代次数-,像我15年前学的,有穷的是重要的。
as long as it's small and finite, will lead to some small infinite errors in the formula, but remember it's got to be in the end made to be vanishingly small.
只要它只是有限小,就会在公式中引起无限小的误差,但请记住,Δt最后变得难以察觉地小
