Oliver Heaviside:


Oliver Heaviside

Electrical engineer, mathematician and physicist
Born: 18th May 1850 in Camden Town, England
Died: 3rd February 1925 at Torquay in Devon, England and buried in Paignton cemetery
English Nationality
Company: Great Northern Telegraph Company
Tutor: Charles Wheatstone

Oliver Heaviside, was diagnosed with scarlet fever in his youth, resulting in being partly deaf, a condition that has been aggravated by time. Although a keen student with top scholastic achievements, he left formal education at the tender age of 16, never to return but remained a pupil al his life by way of self-education. After he schooled himself as a telegraph operator his first employment was in Denmark and then he return and was employed by the Great Northern Telegraph Company and in 1872 was chief operator in Newcastle up on Tyne where he researched the particulars of electricity. To focus on this research he left his post and from this domiciliate at his parent's abode he was instrumental in formulating “transmission line “ hypothesis. His mathematical equality statements accelerated the effectuation of cable messaging.

He researched the electrical phenomenon of high-frequency alternating current to distribute near the surface of a conductor in 1880. He recalculated Maxwell's mathematical sequences and series and integration and differentiation to today's transmitter nomenclature and largely uncomplicated the procedure. This led to the formulation of “Differential operators”mathematical calculations (1887) and because of cogency was vigorously contested at the time. Another controversial doubtful, with doubtful ethic's, aroused with the company AT & T, filing patents on the basis of Heaviside's inventions, later offering him compensation, which he declined, because the company failed to fully acknowledged his contribution. At this stage Heaviside was financial stretched to the limit, which tells something of his character. During 1888 and 1889 Heaviside wrote two articles, formulating contortions in the magnetic and electric space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it and the phenomenon that follows by moving into a more compact environment. These formulations also anticipated the “Lorentz and Fitzgerald Contraction” described in detail by Fitzgerald and Hendrik Antoon Lorentz, a Dutch physicist noted for work on electromagnetic theory (1853-1928).

Sir Joseph John Thomson a English physicist who experimented with the conduction of electricity through gases and who discovered the electron and determined its charge and mass (1856-1940) led to Heaviside researching the idea of aggregate electromagnetic volume. He covered it as material volume and later was confirmed by research from other scientists.
He was a self-made expert in electrical science, mathematical science and physicist, mostly by studying on the side, and was the critical factor in solving most of the complex obstacles in perfecting inter-continental telegraph communication and a scientifical influence over an extended period of time, although not popular with the establishment.

Heaviside in 1891 was invited as Fellow of the Royal Society by the British Royal Society for his individual efforts in endeavoring identification and formulation of electromagnetic occurrences. He in 1902, presented for consideration the being of the ionosphere, corroborated in 1923 - the outer region of the Earth's atmosphere which contains a high concentration of free electrons, which was consequently named the Kennelly - Heaviside Layer.

The University of Göttingen in 1905 bestowed him an honorary doctorate which was most befitting and pleased him tremendously. As is the case with most people in their later life Oliver Heaviside's, demeanor became literary bizarre, not relinquishing is thoughts about his fellow scientist. After his death in 1925, the scientific society posthumously gave recognition of his contributions.

 

Inventions and theories:
simplified Maxwell's equation of electromagnetism” 1880
“Reactance” - opposition to the flow of electric current resulting from inductance and capacitance (rather than resistance)
“Heaviside step function” 1880
“Linear differential operators”
“Vector calculus analysis” - Poyington vector
“Heaviside condition”
“transmission-line theory” - telegraphers equations
“Kennely / Heaviside layer” - ionosphere 1902

 

Electromagnetic technical terms:
conductance - A material's capacity to conduct electricity; measured as the reciprocal of electrical resistance – 1885
permeability - The property of something that can be pervaded by a liquid (as by osmosis or diffusion) – 1885
inductance - (physics) a property of an electric circuit by which an electromotive force is induced in it by a variation of current – 1886
impedance - A material's opposition to the flow of electric current; measured in ohms - 1886

Interesting about these words, he had to invent the words because he could not describe the object or function, because it never before exited.

Faraday Medalion

Legacy:
Why have we included this man's life in our discussions? Although not totally deaf he was since childhood acutely hard of hearing. Typically he would avoid assemblies because of his hard of hearingness. As many Deaf persons, he chose to avoid contact as far as possible. Throughout his life he was suspicious about society.
What is remarkable is the fact that he applied himself, mostly without formal training, studying on his own and opened his mind. He applied the power of his mind and inventions came to him. He is the obvious example of any man using what is at hand and shifting his environment towards his destiny, despite his hearing defect, a creative man of integrity, exactly as he was supposed to be.
