Biography Oliver Heaviside (Heaviside Oliver)
(1850-1925)
Born May 18, 1850 in London. He worked in the telegraph company in Newcastle, in 1874 was forced to leave work because of progressive deafness. Scientific studies conducted in our own laboratory. The main physical works are devoted to electromagnetism and mathematical physics. In 1892 engaged in the theoretical aspects of the problems of telegraphy and transmission of electric signals. He suggested increasing the inductance of telephone lines to improve telecommunications. Introduced the concept of impedance, ie. impedance sinusoidal alternating current electrical circuit containing capacitance and inductance. In the multi-volume work Electromagnetic Theory (Electromagnetic Theory, 1893-1912) put forward the hypothesis of the existence of the ionized layer of atmosphere that can reflect radio waves (the ionosphere). (Regardless of the Heaviside and almost simultaneously with this hypothesis expressed A. Kennelly of Harvard University.) Is one of the founders of the operational calculus.
Heaviside died in Torquay (Devon) 3 February 1925.
