The 4-space equations of hydrodynamics and electrodynamics are constructed using this dyadic calculus. As a demonstration of the relationship between gravity and electrodynamics a time varying metric is shown to generate electromagnetic radiation.Rev4: The byline has been updated and a consistent system of units is used with c=1Classical PhysicsGeneral Physicstext
