History links The prediction of electromagnetic waves by Maxwell and the demonstration of their existence by Hertz led several scientists to speculate that celestial objects, such as the Sun and stars, might generate radio waves. The following scientists set the groundwork for the later discovery of radio astronomy. Click on each one for a summary of his contibutions. The unexpected discovery by Jansky of radio waves from the Milky Way, and the follow-up work by Reber, convinced the scientific world that radio astronomy was a new and important way of studying the universe. In the 1860s and 1870s, James Clerk Maxwell developed the theory of electric and magnetic forces, summarized in his famous four equations. These equations encapsulated all that had been discovered about electricity and magnetism in the experiments done over the previous few hundred years by Faraday, Volta, and many others. They showed that electricity and magnetism were two aspects of the same force. The equations also predicted that there should be a form of radiation, which came to be known as electromagnetic radiation. Maxwell realized that light was a form of electromagnetic radiation. Around 1862 he wrote

El principio de la comunicación por radio: Un transmisor de radio produce una radiación electromagnética concentrada de una determinada frecuencia, siendo recogida por una antena. De todas las ondas que entran en contacto con ella, el receptor tan solo amplificará las que esten sintonizadas con él.

Extractions: Jules Henri Poincare. Poincare was deeply involved in the mathematics relevant to problems of celestial mechanics, the three-body problem, and theories of light and electromagnetic waves. He is credited by many as a codiscoverer (with Albert Einstein and Hendrik Lorentz) of the special theory of relativity. He helped place celestial mechanics on a rigorous basis in two major works: New Methods of Celestial Mechanics (3 vols., 1892-99; Eng. trans., 1967) and Lecons de mecanique celeste (Lessons of Celestial Mechanics, 1905-10). Of his most popular and philosophical writings, notice must be made of Science and Hypothesis (1901; Eng. trans., 1905), Science and Method (1908; Eng. trans., 1914), and The Value of Science (1904; Eng. trans., 1907).

Heinrich Ruldoph Hertz .The German physicist, engineer, and mathematician Heinrich Rudolph Hertz, b. Feb. 22, 1857, d. Jan. 1, 1894, was the first person to demonstrate the existence of radio waves. His chief inspiration was Herman von Helmholtz. After studying the work of James Clerk Maxwell, Hertz demonstrated in 1887 that the velocity of radio waves (also called Hertzian waves) was equal to that of light. His work ordered the field of electrodynamics, putting an end to fruitless arguments about action at a distance. The unit of frequency (one cycle per second) is named the hertz in honor of Hertz's work. J. Z. Fullmer Bibliography: Appleyard, Rollo, Pioneers of Electrical Communications (1968).

Extractions: The Heaviside Signal An alternative view of the transverse electromagnetic wave. By Ivor Catt Wireless World, July 1979 Maxwell faced up to the paradox that whereas electric circuits, in order to function properly by allowing the passage of electric current, were thought to require a complete closed circuit of conductors, electric current still seemed to flow for a time when a capacitor (which of course is an open circuit) was placed in series with the closed loop of conductors. He cut the Gordian knot (according to Heaviside in his Electromagnetic Theory , 1893, London, p28 sect 30) by postulating that a new kind of current, which he called displacement current, leapt across the plates within the capacitor. This electric current, which was uniformly distributed in the space between the capacitor plates, could even flow through a vacuum. Maxwell followed up this daring idea by suggesting that electromagnetic waves might exist in space. Scepticism about his postulated displacement current was silenced in 1887 when Hertz discovered the predicted waves in space. The classic pre-Popperian requirement of a good scientific theory seemed to have been met the prediction of further results which are later confirmed by experiment. There are two versions of the transverse electromagnetic wave, the rolling wave, and what we shall call here the Heaviside signal. We shall discuss only the wide variety of views among those who believe (with the relativists) that there is no instantaneous action at a distance.

Extractions: B y the year 1887, the 36-year-old Oliver Lodge was already regarded in Great Britain as a highly accomplished scientist. A professor of physics at the newly-established University College in Liverpool, he was known for his brilliant scientific mind and ability to explain complex scientific principles in a manner that could be understood by virtually anyone. In 1887, the Royal Society of Arts asked Lodge to prepare a series of lectures, to be given the following year, concerning how buildings might best be protected from lightning damage. The designers of the lightning protection systems of that time assumed that lightning was a continuous direct current discharge. They believed that protection from lightning could be obtained by placing copper rods above the buildings and connecting them to the earth by means of heavy copper grounding cables with a very low dc resistance. The lightning protection "experts" could not understand why lightning discharges frequently ignored the copper conductors and chose what seemed to be higher resistance "alternate paths" to ground.

Extractions: "Jokainen meistä jättää eläissään maailmaan jonkin merkin, hyvän tai pahan, ja jatkaa elämäänsä ihmiskunnassa". Tämä on eräänlaista sielun kuolemattomuutta; sieluja on pieniä ja suuria, kuten Shakespeare ja Newton, jotka elävät parhaimmillaan vasta jätettyään kuolevaisen tomumajansa. "Maxwell kuului heidän joukkoonsa. Hänen sielunsa elää ja kasvaa kauaksi tulevaisuuteen, ja tuhansien vuosien päästä se paistaa meille yhtenä menneisyyden kirkkaista tähdistä". Näin pohdiskeli entinen lennätinvirkailija Oliver Heaviside päiväkirjassaan vuonna 1886. Hänen käsityksensä jakoi kahdeksankymmentä vuotta myöhemmin nobelfyysikko Richard Feynman, joka totesi: "Ihmiskunnan historian pitkästä perspektiivistä käsin ... ei ole epäilystäkään, että 19. vuosisadan merkittävin tapahtuma on Maxwellin sähködynamiikan lakien löytäminen". He olivat molemmat oikeassa. Skotlantilainen James Clerk Maxwell kuuluu fysiikan kirkkaimpaan pantheoniin Newtonin ja Einsteinin rinnalle. Hän oli mies joka selitti valon luonteen ja sen tehdessään muovaili ensimmäisen yhtenäisteorian. Maxwell oivalsi näet, että valo, sähkö ja magnetismi ovat saman perusilmiön eri ilmentymiä. Mutta siinä missä Einstein ja Newton ovat saavuttaneet ikoniset mittapuut, Maxwell on liki tuntematon. Jopa syntymämaassaan Skotlannissa hän on, skottilaisen kollegani sanoin, yhtä tuntematon kuin suomalainen nobelkirjailija.

oliver heaviside TELEPHONY'S GENIUS. Dick Reiman, Historian. The following isa summary of the article by Paul J. Nahin in the July issues of Spectrum.
http://ieee.cincinnati.fuse.net/reiman/04_1990.html

Extractions: When the pioneers of telephony are mentioned, Alexander Graham Bell and Lord Kelvin, one important name is often omitted: Oliver Heaviside. Yet it was his formula for loading telephone lines to avoid signal distortion that made transatlantic communications possible. The odds of his genius being recognized were formidable. He was a "first rate" eccentric, taking delight in scathing remarks and satire at his critics. He was a child of poverty and seemed to seek it for himself. He attacked problems for which the giants of his time, James Clerk Maxwell, Lord Kelvin, and Gustav R. Kirchoff had not achieved practical solutions. Heaviside designed an operational calculus which got the right answers to difficult problems. His methods were said to be "imperfect" and "of no consequences." He replied that these critics were "wooden-headed."
