Metamatrial ---- Magnetic Monopoles ---- Weber Electrodynamics ---- Light as Photons: The differences between light as electromagnetic waves in classical physics and light as Photons... What are the cases or phoenomena that light must be interpreted as photons? ---- Using waves to communicate (radio radiation) (maybe should talk about waveguide that carry radio waves) ---- Fiber-optic cable carrying data ---- Fabry-Perot Instrument ---- Multilayer Coatings ---- Diode lasers ---- The physics of metal detectors
