Another reason I wanted to point this out in terms of the polar coordinates that we're using, is I think they're actually flipped from what you're used to seeing in physics.

另一个我想指出,我们采用极坐标的原因是，我认为它们实际上是,从你们习惯于看到的物理学中出来的。

In terms of the Schrodinger equation, we now can write it in terms of our polar coordinates here.

在薛定谔方程中，我们现在可以用,极坐标的方式来表示了。
