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。
-
But whereas the other one was obviously forever, this allows you to specify a finite number of times that you wanna do something.
但又不同于“无限循环“,你可以根据需要,为它指定循环次数。
-
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
-
You have discrete random variables, like the one I just defined, or there are also--which take on only a finite number of values-- and we have continuous random variables that can take on any number of values along a continuum.
就像刚定义的,是一个离散型随机变量,随机变量还可以有无限种取值,也就是连续型随机变量,随机变量可以取某一区间的一切值
-
Do the following a bunch of times, but a finite number of times which might be useful.
按照下面重复若干次，有限次数就足够了，这很有用。
-
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。

DNA also has this sort of combinatorial system where you have a finite number of, I guess, bases or amino acids that could combine to a possible infinity of strings of DNA strings.
脱氧核糖核酸也拥有这种组合系统,你的生物基础或氨基酸数量是有限的,但却能组合出,几乎无限的脱氧核糖核酸螺旋结构
-
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。
-
How can you go from a finite list of symbols to an infinite number of sentences?
你如何使有限的符号,变成无限的句子
-
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。
