	Heinrich Hertz 'Hertzian Waves' (Site not responding. Last check: 2007-11-06)
		Heinrich Hertz, a German physicist who was born in 1857 and died of blood poisoning in 1894 at the age of 37, applied Maxwell's theories to the production and reception of radio waves.
		Hertz's condenser was a pair of metal rods, placed end to end with a small gap for a spark between them.
		With this oscillator, Hertz solved two problems: 1) timing Maxwell's waves (he had demonstrated, in the concrete, what Maxwell had only theorized: that the velocity of radio waves was equal to the velocity of light), and 2) how to make the electric and magnetic fields detach themselves from wires and go free as Maxwell's waves.

	Reflections on Hertz and the Hertzian Dipole
		Only Heinrich Hertz was likely to have produced such a multivalent device, because only he among all his contemporaries had combined Helmholtz’s approach to physics with superb laboratory acumen and analytical finesse, all mixed finely and potently with an intense desire for professional recognition.
		Hertz absorbed from his mentor the notion that proper and effective physical theories are built on the basis of potential functions that represent the interaction at a given moment in time between two physical objects.
		Hertz was quite familiar with this possibility from Helmholtz’s work, and he clearly did not like it, since in 1884 he had produced his version of Maxwell’s equations without using the ether at all.

	IEEE Heinrich Hertz Medal
		The IEEE Heinrich Hertz Medal was established by the Board of Directors in 1987 'for outstanding achievements in electromagnetic waves.' It may be presented annually to an individual for achievements which are theoretical or experimental in nature, and which have been achieved in any year preceding the award.
		The medal is named in honor of the renowned scientist whose experiments verified Maxwell's theory and proved that all forms of electromagnetic radiation are propagated as waves at a finite velocity - - the speed of light.
		The Medal was proposed in 1986 by the IEEE Germany Section in Region 8 as centennial recognition of Hertz's experiments, which took place from 1886 to 1891.

	The Photoelectric Effect
		The experiment was very successful - Hertz was able to detect the radiation up to fifty feet away, and in a series of ingenious experiments established that the radiation was reflected and refracted as expected, and that it was polarized.
		To quote from Hertz again (he called the transmitter spark A, the receiver B): "I occasionally enclosed the spark B in a dark case so as to more easily make the observations; and in so doing I observed that the maximum spark-length became decidedly smaller in the case than it was before.
		He then found a slab of quartz did not shield the spark, whereupon he used a quartz prism to break up the light from the big spark into its components, and discovered that the wavelength which made the little spark more powerful was beyond the visible, in the ultraviolet.
