1.   can not  define  equation  when not known  E

> Curl(E);
Error, (in Vector) dimension parameter is required for this form of initializer
 
Curl(E) = 0
Gradient(E) = p/e0
E = -Gradient(V)
 
how to  solve for  poisson equation for  finding  potential  and then  calculate  electric  field,  force , energy?
 
2.  when  doing first  quantization of maxwell,  i  remember that it  need to  do  substitution,  how?
 
all  for  photonic  physics  experiment,  but  example  in  http://www.mapleprimes.com/posts/200457-Computer-Algebra-For-Theoretical-Physics
using  3  dimension  variables, why?
 
why  use  3 dimension  x, y,z  for  photonic  experiment?
but  in  electronic  experiment only  measure  voltage  potential  or  current,  how  they relate?
 
would like to detect photon and build a control system to regulate photon electromagnetic wave like wireless system
