Re: [Phys-l] two kinds of electrical charge ????????

On a more serious note, how many types of color charge are there?  John
argues that there is only one type of electric charge, just as there is
only one type of mass charge, because each can be described by one
independent variable.  The only difference is that mass charge is
limited to non-negative values, but electric charge can be positive,
zero, or negative.  How many independent variables are needed to
describe color charge?

Hmm, if there is only one type of charge, how many types of mass are 
there?  One-half of a type?

(Not even sure if that rises above the level of a joke. :-)
