The narrative begins with the basics. Scalars and vectors are introduced not as abstract ornaments but as instruments—tools for describing potential differences, current directions, and force lines. Coordinate systems shift like camera angles: Cartesian for local intuition, cylindrical for coaxial cables and wires, spherical for antennas and radiating spheres. Each change of coordinates is a change of perspective, teaching the reader to choose lenses that simplify the problem at hand.
