	Biography of Philipp von Lenard (Site not responding. Last check: 2007-10-09)
		Lenard's first work was done in the field of mechanics, when he published a paper on the oscillation of precipitated water drops and allied problems and in 1894 he published the Principles of Mechanics left behind by Hertz.
		Although Lenard at first followed Hertz in believing that the cathode rays were propagated in the ether, he later abandoned this view as a result of the work of Jean Perrin in 1895, Sir J.J. Thomson in 1897 and W.
		In the course of his work Lenard had, for the purpose of accelerating the speed of the electrons and measuring their energy, invented a photoelectric cell which was the first model of the "3-electrode lamp" which is so important today in radioelectric technique.

	Philipp Eduard Anton von Lenard
		Philipp Eduard Anton von Lenard, in Hungarian Fülöp Lénárd (born in Bratislava on June 7, 1862 –; died May 20, 1947 in Messelhausen) was a physicist and the winner of the Nobel Prize for Physics in 1905 for his research on cathode rays and the discovery of many of their properties.
		Lenard studied under the illustrious Bunsen and Helmholtz, and obtained his doctoral degree in 1886 at the University of Heidelberg.
		Lenard overcame these problems by devising a method of making small metallic windows in the glass that were thick enough to be able to withstand the pressure differences, but thin enough to allow passage of the rays.

		Philipp Eduard Anton von Lenard (June 7, 1862 – May 20, 1947) was a German physicist and the winner of the Nobel Prize for Physics in 1905 for his research on cathode rays and the discovery of many of their properties.
		During the Nazi time he was the outspoken proponent of the idea that Germany should rely on "Deutsche Physik" (best translated as "Aryan physics") and ignore the (in his opinion) fallacious and maybe even deliberately misleading ideas of "Jewish physics" (by which he meant chiefly the theories of Albert Einstein).
		It is hence sort of amusing to remark in this context the important role that Einstein's explanation of the photoelectric effect plays for appreciating the value of Lenard's work on cathode rays: without Einstein's theory demonstrating the importance of Lenard's observation, he might not have been awarded a Nobel prize.

		This means that the cause of the light emission is that the coating is hit by rays which are emitted by the cathode, proceed towards the anode in straight lines, and continue at least partly past it.
		This phenomenon has been studied in great detail in the field of physics toward the end of the 19th century, yielding a Nobel prize for Philipp von Lenard.
		It was soon understood that the cathode rays consist of the actual carriers of electricity which are now known as electrons.

	biology - Photoelectric effect
		In 1902 Philipp von Lenard observed [1] the variation in electron energy with light frequency.
		For example, an increase in frequency results in an increase in the maximum kinetic energy calculated for an electron upon liberation - ultraviolet radiation would require a higher applied stopping potential, to stop current in a phototube, than blue light.
		However Lenard's results were qualitative rather than quantitative because of the difficulty in performing the experiments: the experiments need to be done on freshly cut metal so that the pure metal was observed, but it oxidised in tens of minutes even in the partial vacuums he used.

		Philipp von Lenard studied physics successively at Budapest, Vienna, Berlin and Heidelberg under Bunsen, Helmholtz, Königsberger and Quincke and in 1886 took his Ph.D. at Heidelberg.
		His research led him to the great discovery called the "Lenard Window." His research led to conclusions that conflicted with current theory and were not explained until 1905, when Einstein produced his quantitative law and developed the theory of quanta of light or photons, which was verified much later by Millikan.
		His interest in game-theoretic problems in a narrower sense was first aroused by John Nash's four brilliant papers, published in the period 1950-53, on cooperative and non-cooperative games, on two-person bargaining games and on mutually optimal threat strategies in such games, and on what we now call Nash equilibria.

		Following a suggestion by Max von Laue (1879-1960) in 1912, the father and son team, Sir William Henry Bragg (1862-1942) and Sir William Lawrence Bragg (1890-1971), perfected the technique of measuring wavelength of X-rays using a crystal (say Nacl) as a diffraction grating.
		Rontgen had observed that the X-rays could not be reflected or refracted, however, the first positive evidence for their refraction and reflection came from the work of Stenstrom by passing a beam of X-rays through a crystal.
		Lenard saw intense, easily visible fluorescence of the ketone screens and intense flening of photographic plates, but "only for a distance in air of a few centimeters".
