(MUSCI) The Cheongdo bullfighting festival attracts country and city dwellers alike - not by pitting bull against man, but by squaring off bull against bull.

We knew this was trying to do squaring, so intellectually we know we can square -4, it ought to be 16, but what happens here?

我们知道程序是用来求平方数的，那么按理说我们可以来求-4的平方，也就是16，但是程序结果是怎么样的呢？

So again, we can think about the probability density in terms of squaring the wave function.

同样的，我们可以把,波函数平方考虑概率密度。

Right, It's just squaring an integer, is what it's doing.

对了，这个程序就是，用来求一个整数的平方的。

And when we're looking at the probability density graphs, it doesn't make a difference, it's okay, It has no meaning for our actual plot there, because we're squaring it, so it doesn't matter whether it's negative or positive, all that matters is the magnitude.

它的概率密度图的时候,两者没什么区别，这是可以的，它对我们画这个图，没有什么意义,因为我们是取平方，所以它的正负，无所谓，只和幅值有关，但当我们说到。
