Max Planck and the resolution of the blackbody problem; the classical view of radiation interacting with matter; Planck's act of desperation; a model of how radiation and matter actually interact; the energy of a light quantum; the photoelectric effect; a classical analogy; the failure of classical physics in the photoelectric effect; Einstein applies Planck's idea to the photoelectric effect and resolves it; the quantum picture emerges.
