    The charge sources enter through the equation d*F=*J, where *J is the three-form dual to the current four-vector J=(r,j). In the rest frame of the charge density r, J=(r,0), so *J is r times the the volume element for three-dimensional space. In a three-dimensional space, a surface that can be localized in three dimensions (has codimension three) must be a zero-dimensional surface, also known as a point.
    This is the math that tells us that the Maxwell equations couple electrically to sources that are points, or zero-branes, as zero-dimensional objects are now called in string theory. (For magnetic couplings, the roles of F and *F are interchanged, but that won't be covered here.) This same math works for two-forms in any spacetime dimension, so we know that Maxwell's equations couple to point charges in any spacetime dimension.
    Close enough?

    I cannot confirm nor deny that WDF is undergoing a design change. You're crazy for thinking that. Stop being so crazy.

    Well, in my craziness I must ask that if, per se, there really is a design change coming, neither denied nor confirmed, when would it come into existance for the common user such as myself? If it's really true.....

    Gees that's crazy.
