    Why if one breaks a hologram into little pieces, the information is found entirely on every piece ( it isn't lost as it happens with a photo which is tored into pieces), excepting only the view angles -like watching through a smaller window.
    Isn't there a definite diffraction pattern?
    How are there made "rewritable holograms"?
