|    a single photon    |

      From: r_delaney2001@yahoo.com              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.              --       Rich              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
