Example... "Young's double slit experiment" http://en.wikipedia.org/wiki/Double-slit_experiment The classical wave explanation gives the characteristic interference fringes as per... http://en.wikipedia.org/wiki/Double-slit_experiment#Classical_wave-optics_formulation Quantum mechanics gives the same output, but uses an extremely ugly probability equation the get the result. So what happens when you have an extremely weak light source such that only one photon is present in the device at any time? Surely it won't have anything to interfere with and cause a diffraction pattern? Wrong. The exact same interference fringe pattern shows up, although it obviously takes longer for the photographic film to expose. This effect even works when sending electrons 1-at-a-time through a double slit filter (Taylor's Experiment) http://www.thestargarden.co.uk/QuantumMechanics.html -- Walter Dnes <waltd...@waltdnes.org> I don't run "desktop environments"; I run useful applications
