Actually, the "conventional theory" (and the mathematics) say that "current"
(not electrons) flows from positive to negative (was that why positive and
negative were chosen?).  Many years later, when electrons were discovered,
it was found that they move from negative to positive.  While it does not
effect the mathematics, this knowledge makes a few things like the mechanics
of cathode ray tubes a little easier to understand.  Holes are another
story.
