   I was taught that electricity is the flow if electrons in one direction, I think charges exist 
and change but I never head of charges "flowing" and holes flow in the other direction.

   Conventional current flow {reverse of electron flow} (used by Heath ?, GE, colleges) was a from 
pre-electronics battery charging times.  The operation of the CRT disproves conventional current 
flow if nothing leading up to it does.  Why many college professors STILL teach conventional current 
flow has mystified me for over 50 years.
