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。

And that's why all those reactions, first of all, in some sense what I put up was kind of a trivial statement in actual fact saying they all happen spontaneously because I didn't specify what we were starting with exactly, what concentrations we were starting with.

首先这就是为什么所有的这些方程，在某种程度上,我举得这些例子说它们自发产生,这是一个琐碎的陈述,因为我没有说明，我们从什么地方开始。

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。
