   a single photon

   Let's say you radiate a pulse of energy from   
   a dipole antenna at 100 MHz, equal to a single   
   photon. Sort of tiny, but elctrical engineers   
   are a clever lot, I'm sure they're up to it.   
      
   Now according to Maxwell, you get a EM wave   
   which spreads almost uniformly through the   
   univese, growing thinner and thinner.  And   
   aliens everwhere can pick up some trace of   
   it.  (assume very low noise circuitry)   
      
   But according to Planck et al., which we   
   accept as truer, there's just a single photon,   
   which a single Klingon, somewhere, observes.   
   Everyone else sees nada.   
      
   I don't get how to reconcile these pictures.   
   In particular, how to reconcile a vector field,   
   with separate E and H components, vs. a package   
   of energy.  Some people will jabber "classical   
   theory is an approximation of the flat manifold yada yada".   
      
   Sorry, that cuts no ice.  My idea of approximation   
   is:  "the rug measures 38.4 sq. ft, +- .2 sq. ft"   
   The Maxwell model isn't remotely close to the Planck model.   
      
   This isn't a usual question for this board, but there   
   are people here who know some physics.
