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
