Angular_momentum 10:07, 10 April 2008 Xxanthippe ... (consistent) 

You undid some of my corrections on the angular momentum page.
The problem is that in a single formula the letter  is used as an index and as the imaginary number at the same time. While you and I might not have too many problems understanding this it is a incredibly confusing for people who do not know the topic so well.

For example look at the exponential function:

and ask yourself who wound understand that notation (correctly).

To be correct and consistent one would have to change all indexes.
