Fine and clean. <br/><br/><em>First apperance of the famous Franck-Hertz Experiment which is considered as a new and independent support not only of Planck's quantum theory and Einstein's light-quantum hypothesis but also of Bohr's theory of the atom with stationary states of discrete energies.Franck and Hertz were awarded the Nobel Prize in Physics in 1925 for this work and Franck concluded his Nobel lecture with the words "We know only to well that we owe the wide recognition that our work received to contact with the great concepts and ideas of M. Planck and in particular Niels Bohr.""In their famous experiments Franck and Hertz' showed that electrons could impart energy to a mercury atom only if they had a kinetic energy exceeding 4.9 ev. and that exactly this quantum of energy was taken up by the mercury atom causing it to emit light of the resonance line Å 2537. It was the first direct proof of the quantized nature of the energy transfer and of the connection of the quantum DeltaE of energy with the frequency p = DeltaE/h of the light emitted as the result of the transfer. These experiments are rightly regarded as the first decisive proof of the reality of the quantized energy levels that had just been postulated by Niel’s Bohr."

Discoveries of Modern Physics in 100 Episodes" Episode 25 The Franck-Hartz Experiment 1914 pp. 102-104.The volume contains another importent paper ALBERT EINSTEIN "Beiträge zur Quantentheorie" pp. 820-828. First edition. "In this paper. two considerations are given which are interrelated by a common goal inasmuch as it is attempted to derive two of the most importent achievementss of quantum theory viz. Planck's radiation law and Nernst's third law of thermodynamics in a new manner. The proofs do not involve Boltzmann's equation and are thus based enterely on macroscopic thermodynamics. They do introduce however the quantum hupothesis. Einstein points out that the alleged 'proofs' which try to derive the theorem of Nernst from the mere fact that the heat capacity of all substances goes to zero at absolute zero temterature are not genuine."

Planck's paper pp.35-46. <br/><br/><em>Max Planck is considered to be the founder of the quantum theory and was awarded the Nobel Prize in Physics in 1918. "Über irreversible Strahlungsvorgänge" is a mathematical description of the electromagnetic radiation emitted from a black-body."Über irreversible Strahlungsvorgänge was published in five parts in the period 1897-1901 the present volume being number 1."With the Kirchhoff-Wien-Boltzmann work as a background Max Planck began his attack on the black-body problem in 1897. He labored under the erroneous impression for some time that Wien's formula was the only one which harmonized with the second law of thermodynamics. The experiments on black-bodies due to Lummer and Pringsheim Rubens and Kurlbaum forced him from that position." Planck Max. Catalogue 258 Interlibrum Vaduz "I had already been struggling with the problem of the equilibrium of matter and radiation for some years without success; I knew the problem is of fundamental significance for Physics." The significance was unparallelled when he in December 1900 delivered a paper entitled "On the Theory of the Energy Distribution Law in the Normal Spectrum" before the German Physical Society which today is considered the birth of quantum physics. The present volume constitutes a precursor to this work. - Akademie No 33 </em> unknown
