Re: [Phys-l] About light interference and energy preservation

However--I would go back to the original text and be sure that Assimov 
actually says what you paraphrased --that is, does he actually say the dark 
regions of the screen heat up--as opposed to saying the energy of the 
photons are absorbed in the screen.  Maybe he doesn't pinpoint that the 
'hot' spots are in the bright areas--but does he really say they are in the 
dark areas?  The rest of this has been sufficiently dealt with by others.
