It uses average yearly data in its computations, and focuses on only two major pollutants - nitrogen and phosphorous.

Third thing we want you to do, is to understand the fundamental both capabilities and limitations of computations, and the costs associated with them.
我们希望你们做的第三件事儿,就是了解,计算的基本能力,和局限以及他们的代价。
OK, and that leads now to an interesting question, which would be, "How do I build a mechanical process to capture that set of computations?"
好,现在出现了一个有趣的问题,就是“我怎么样才能建立计算机程序,去捕捉一系列的计算呢?
There will be some computations, so something to calculate with.
考试中会有计算,所以需要计算工具。
This just illustrates how massive this computations are, how significant they are.
这正解释了这些计算指令是多么庞大,多么重要。
We know machines have limited capacities to engage in mathematical and logical reasoning, to recognize things, to do various forms of computations, and this makes it at least possible that we are such machines.
我们也知道机器,在数学推理与逻辑推理方面,在识别物体方面,在完成各种形式的运算方面,的确是拥有有限的能力的,这至少说明,人类就是这样的机器
Because it says, your program will still give you a value, but it may not be what you intended, and you can't always tell, and that may propagate it's way down through a whole bunch of other computations before it causes some catastrophic failure.
因为这意味着,你的程序依然会返回一个值,但是这个值可能不是你想要的,你可能还分辨不出来,而且这种情况会传播,结果会沿着正果计算过程传播下去,直到产生一个灾难性的错误。
But there are an awful lot of computations for which this is the right way to do it.
对,可能,这要花一会儿功夫。
And that latter statement sounds funny, you don't think of computations having limits, but they do.
这个说法听起来挺逗,你们不会认为计算有局限性,但事实上他们有。
