Innovations and discoveries

Heaviside advanced the idea of the Ionosphere, making the prediction of the Kennelly-Heaviside Layer. Heaviside developed the transmission line theory (also known as the "telegrapher's equations"). Heaviside independently co-discovered the poynting vector.

Maxwell reformulation and mathematics

Heaviside simplified and made useful for the sciences the original Maxwell's equations of electromagnetism. This innovation from the reformulation of Maxwell's original equations gives the four vector equations known today. Heaviside developed the Heaviside step function, which he used to model the flow of current in an electric circuit. Heaviside developed vectors (and vector calculus). Heaviside formed the operator method for linear differential equations.

Electromagnetic terms

Heaviside coined the term "electret" for the electric analogue of a permanent magnet, or, in other words, any substance that exhibits a quasi-permanent electric polarization (e.g. ferroelectric). In September of 1885, Heaviside coined the term "conductance" and "permeability". In February of 1886, Heaviside coined the term "inductance". In July of 1886, Heaviside coined the term "impedance". In December of 1887, Heaviside coined the term "admittance". In May of 1888, Heaviside coined the term "reluctance". In June of 1887, Heaviside used the term "permittance" which later became susceptance.
