Описание к видео Oliver Heaviside Electromagentic theory volume one Chapter 2 paragraphs 22 and 23

Oliver Heaviside's comment on the medium. If, for example, H be imagined to be the velocity of a substance, then one half μ H squared is its kinetic energy, and μ its density. And if E be a torque, then one over c the elastivity is the corresponding coefficient of elasticity, the rigidity, or quasi-rigidity, as the case may be ; whilst c is the coefficient of compliance, or the compliancy; and one half c times E squared is the stored energy of the strain.
