- when we introduce things like the square
root of -1.
而在我們引入像-1的平方根的時候，那就簡直無法理解了。
- it is the square root of -1. All adding is
some combination of sliding sideways
它是-1的平方根。所有增加的是 側向滑動的一些組合

- In general, it'll be the inverse tangent of the square root of the small mass over
在這個例子中，該值為 -10
- the square root of the big mass.
這代表著 tan(θ) 也就是對邊除以鄰邊 將會是上升量除以負的橫移量

- You're cheating a little bit because rather than having a value, it's a complex number. That means to say a real part plus i times an imaginary part where i is the square root of minus one. But okay, who cares? What you need to know is there's a profile. There's a shape. There's basically a value at every point in space which says this is the wave function of the electron at every point in space. So go ahead and visualize it. If you ever took chemistry class and you saw those images of what are called orbitals and different kinds of atoms, those are literally pictures of wave functions.
你有點作弊，因為它不是一個數值，而是一個複數。也就是說，實部加 i 乘以虛部，其中 i 是負 1 的平方根。不過沒關係，誰在乎呢？你需要知道的是有一個輪廓。有一個形狀。基本上，空間中每一點都有一個值，表示這是空間中每一點的電子波函數。所以，請繼續想象它。如果你上過化學課，看到過那些所謂的軌道和不同種類原子的圖片，那些就是波函數的圖片。
