What is that? It's the piece of code we wrote for computing square roots, square roots of actually perfect squares.
对吧?这是什么呢?,这是我们写的计算平方根的代码,计算完全全平方根的。
All right, this is actually a very old piece of imperative knowledge for computing square roots, it's attributed to Heron of Alexandria, although I believe that the Babylonians are suspected of knowing it beforehand.
好,这是一个很古老的,关于计算平方根的程序性知识,是亚历山大的海伦提出的,不过我怀疑在那之前,巴比伦人就已经猜想过了。
It's our vision for the future of computing.
这是对于未来计算的一个愿景。
So, it's an extraordinarily complicated computing device.
所以这是个极端复杂的运算器
For Problem Set 1, as you may have seen already, ; what I thought I'd -- I had not, in fact, seen that clip; so I did a quick Googling and that's actually as relevant as the movie really gets I think to computing.
对于习题集1,你们可能已经看过了,事实上,我还没看过这个电影片段;,所以我google了一下,那个实际上是跟,我想要处理的电影是相关的。
And so the program may do different things on different runs. We'll see a lot of that, because it's used a lot in modern computing.
因此程序会对不同的输入做不同的操作,我们会看到很多这样的情况,因为它在现代计算中被广泛应用。
Because that's life in computing.
这并不像一个数学问题集。
