He was born in Camden, London.He had scarlet fever, which made his ears hard to hear.Although his academic achievements were excellent (in 1865, he ranked fifth among more than 500 students), he left school at the age of 16 to learn Morse code and electromagnetism.He becameDenmark Great Northern Telegraph CompanyTelegraph operator.
In 1872, he was the chief telegraph operator of Newcastle on Tyne. He began to study electricity.
In 1874, he resigned and studied alone in his parents' home.During this period, he proposed the telegraph operator equation.He pointed out that the evenly distributed inductance on the transmission line will reduce attenuation and noise. If the inductance is large enough and the resistance is small enough, the current at all frequencies will decay equally, and the circuit will be noise free.
In 1880, he studied the skin effect on telegraph transmission.He will play an important role in electromagneticsMaxwell's equationsTo rephrase, change quaternion to vector, and reduce the original 20 equations to 4 differential equations.
From 1880 to 1887, he proposed calculus (differential operator D was introduced at this time) - a set of methods to transform differential equations into ordinary algebraic equations.Mathematicians criticized this method as not rigorous enough.
In 1887, he proposed to eliminate noise with inductors.Unfortunately, this cannot be implemented for political reasons.Later, George A. Campbell of AT&T and Michael Idvorsky Pupin, an external researcher, studied the method of HAVC and continued to develop it.AT&T has applied for relevant patents, but this includes not only the work of Campbell and Pupin, but also the method of making coiling wire by Havexay.AT&T later offered to buy his job from Havexay, but Havexay refused. He asked AT&T to admit that it was his job.
In 1888 and 1889, he calculated the changes of electric and magnetic fields caused by moving charges, and the impact of charges entering a denser medium.This is related to the later Cherenkov radiation and Lorenz Fitzgerald contraction theory.
Around 1889, under the influence of the electron proposed by Joseph Thomson, Harvey studied the electromagnetic mass.He calculated the electromagnetic mass as the real mass of matter.William Wien later proved that the Hawthorne equation was correct when the speed was much lower than the speed of light.
In 1902, in order to explain the reflection of radio waves, Haversay conjectured that there was a layer of conductive material in the atmosphere, which was called the Kennelian Haversay layer.The existence of this layer was confirmed in 1923.
In 1891 he became a member of the Royal Society.In 1905, the University of Gettingen awarded him an honorary doctorate.In his later years, his character became more and more eccentric, and he finally died in Devon and was buried in Paignton.
