    "abstract": "Based on an analogy between Fluid Mechanics and Electromagnetism, we claim\nthat the gauge conditions of Classical Electromagnetism are not equivalent\ncontrary to the common belief. These \"gauges\" are usually considered as\nmathematical conditions that one must specify in order to solve any\nelectromagnetic problem. Here, the author shows that these conditions are\nphysical constraints which can be interpreted as electromagnetic continuity\nequations. As a consequence, light cannot be considered as a pure transverse\nwave in vacuum from the point of view of the potentials. We discuss the (lack\nof) meaning of gauge transformations.",
