Others though, I want to tell you that it doesn't-- if you're shopping-- I had a student come by yesterday and ask he's a little rusty in his math skills if he should take this course.
其他的,我想告诉你们不必...,如果你还在挑选课程...,昨天有个学生来问我,他的数学有点荒废了,他该不该选这门课
So we've looked at how to solve square root we've, looked at two problems, I've tried to instill in you this sense of paranoia which is so valuable, and now we're going to pull back Python and return to something much simpler than numbers, and that's Python. All right?
我们已经研究了如何去求平方根,研究了两种方法,我一直在尝试着给你们逐渐灌输,要偏执的理念,这样的理念非常有价值,现在我们回过头来去学习一些,比数字更简单的东西,也就是,对不对?数学问题很难?

It's something I study, and I like it a lot, it's very interesting,
这是我学习的内容,我很喜欢数学,很有趣。
But the mathematicians told Dirac, "You cannot ignore the negative energy solution because it tells you there's a second solution and you cannot throw them out."
但数学家们告诉狄拉克,你不能忽略负的能量,因为数学告诉我有两个根,你不能随便丢掉
Then, you go to the Math Department and say, "Please tell me what's the answer to this equation?"

Now as an aside, I'll admit this is a completely useless program, much like the first couple of ones we did because why would you write a program just to solve this?
说点题外话,我承认这是一个完全无用的程序,跟我们之前写的两个程序一样,我们为什么需要写个程序来解决这个数学运算呢?
