	In addition he proposed that induction coils should be located uniformly along telephone in order to decrease signal distortion. Heaviside again got no recognition for this idea. Michael Pupin of Columbia received the patent for the idea years later. He also Invented coax cable and coined the terms reactance, impedance, inductance, admittance, conductance, permeability, permittance, and reluctance in relation to electromagnetic theory.

	Oliver Heaviside recasted Maxwell's equation into vector form. He was able to reduce Maxwell's original twenty equations with twenty variables into four vector equations with only two variables. This is the form that every physicists uses to describe moving and static electric charges and magnetic dipole in addition to electromagnetic induction. In addition Heaviside derived the Lorenze for and discovered the poynting vector.		Oliver Heaviside recasted Maxwell's equation into vector form.

	One of Heaviside's other large accomplishments is his proposal of the existence of the ionsphere. He suggested that this ionsphere could be used to transmit radio signals back to earth because they would follow the curvature of the Earth. This theory was finally verified in 1923.
