The real part 7 is called the -+ conductance and the imaginary part 7" is called the -+ susceptance. The term admittance was coined by Oliver Heaviside in 1887. 

By his application of Laplace transforms to the transient response of electrical circuits, Oliver Heaviside created the foimdation for impedance spectroscopy. Heaviside coined the words inductance, capacitance, and impedance and introduced these concepts to the treatment of electrical circuits. His papers on the subject, published in The Electrician beginning in 1872, were compiled by Heaviside in book form in 1894.6/7 pj-om the perspective of the application to physical systems, however, the history of impedance spectroscopy begins in 1894 with the work of Nemst. ... 

As mentioned earlier, the primary use for the Laplace transforms is to solve linear differential equations or systems of linear (or linearized nonlinear) differential equations with constant coefficients. The procedure was developed by the English engineer Oliver Heaviside and it enables us to solve many problems without going through the troubteof>tr finding the complementary and the particular solutions for linear differential equations. The same procedure can be extended to simple or systems of partial differential equations and to integral equations. 

So far as the tyro is concerned theoretical demonstrations are by no means so convincing as is sometimes supposed. It is as necessary to learn to think in letters and to handle numbers and quantities by their symbols as it is to learn to swim or to ride a bicycle. The inutility of general proofs is an everyday experience to the teacher. The beginner only acquires confidence by reasoning about something which allows him to test whether his results are true or false he is really convinced only after the principle has been verified by actual measurement or by arithmetical illustration. The best of all proofs, said Oliver Heaviside... 

Heaviside-Lorentz units A system of units for electric and magnetic quantities based upon c.g.s. electrostatic and electromagnetic units. They are the rationalized forms of Gaussian units and, like the latter, are widely used in particle physics and relativity in preference to the S1 units now employed for general purposes in physics. They are named after Oliver Heaviside (1850-1925) and Hendrik Lorentz (1853-1928). 

Based upon Faraday s work, James Clerk Maxwell published his famous equations in 1873. He more specifically calculated the resistance of a homogeneous suspension of uniform spheres (also coated, two-phase spheres) as a function of the volume concentration of the spheres. This is the basic mathematical model for cell suspensions and tissues still used today. However, it was not Maxwell himself who in 1873 formulated the four equations we know today as Maxwell s equations. Maxwell used the concept of quaternions, and the equations did not have the modern form of compactness he used 20 equations and 20 variables. It was Oliver Heaviside (1850—1925) who first expressed them in the form we know today. It was also Heaviside who coined the terms impedance (1886), conductance (1885), permeability (1885), admittance (1887), and permittance, which later became susceptance.

Distortionless transmission lines (Oliver Heaviside) Heaviside recommends that induction coils be added to telephone and telegraph lines to correct for distortion. 

The concept of electrical impedance was first introduced by Oliver Heaviside in the 1880s and was soon after developed in terms of vector diagrams and complex number representation by A. E. Keimelly and C. P. Steinmetz [1]. Since then the technique gained in exposure and popularity, propelled by a series of scientific advancements in the...
