First Edition! "Die Ergebnisse der Strahlungstheorie und die neuere Theorie der spezifischen Wärme haben den Nachweis geliefert daß die Elektronentheorie der Metalle auf eine wesentlich neue Grundlage gestellt werden muß. Man kann nicht mehr die Annahme aufrechterhalten daß die Elektronen in einem Metall wie freie Gasmoleküle herumfliegen und daß ihre mittlere lebendige Kraft der absoluten Temperatur des Metalls proportional ist. Solche Elektronen müssen vielmehr wie Lorentz gezeigt hat eine Wärmestrahlung erzeugen die dem Rayleigh-JEANSschen Gesetz folgt das sich bekanntlich mit der Erfahrung nicht in Übereinstimmung bringen läßt. Man würde nach diesem Gesetz für kürzere Wellenlängen eine viel größere Strahlung erhalten müssen als sie erfahrungsmäßig vorhanden ist. Ebenso zeigt die Theorie der spezifischen Wärme welche die Wärmebewegung in festen Körpern als Schwingungen der Moleküle um feste Zentren auffaßt und diese nach der PLANCKSchen Formel statistisch verteilt durch ihre Übereinstimmung mit den Beobachtungen daß die Elektronen nicht an der Wärmeenergie merklich beteiligt sein können." WienWien Wilhelm Carl Werner Otto Fritz Franz Wien 1864-1928 physicist who in 1893 used theories about heat and electromagnetism to deduce Wien's displacement law which calculates the emission of a blackbody at any temperature from the emission at any one reference temperature. He also formulated an expression for the black-body radiation which is correct in the photon-gas limit. His arguments were based on the notion of adiabatic invariance and were instrumental for the formulation of quantum mechanics. Wien received the 1911 Nobel Prize for his work on heat radiation. unknown

Wilhelm Wien 1865-1928 "grew up in the east Prussian town of Rastenburg today Ketrzyn Lithuania. He then studied at the prominent universities of Heidelberg and Göttingen before he eventually completed his doctorate in Berlin. In 1900 he succeeded W.C. Röntgen 1901 Physics Laureate as a professor in Würzburg. Wien's research concerned how various metals radiate heat and he received the Nobel Prize for the law of black-body radiation now known as Wien-Planck's law. It was drawn up jointly with Max Planck Physics 1918 and many felt that they should have shared in the award." "When a completely dark body is heated it emits visible light and other electromagnetic radiation. The spectrum of the radiation is entirely dependent on the temperature of the body and not its composition. In 1893 Wilhelm Wien formulated his displacement law which indicates at which wavelength the radiation is most intense at a certain temperature. He subsequently also formulated a law indicating how the radiation spectrum varies as temperature changes. However this does not apply to long wavelengths and in 1900 Max Planck formulated a law that conforms better." Wilhelm Wien - Facts. NobelPrize/org The Nobel Prize in Physics 1911 unknown
