This technique, made possible by their invention of the spectroscope, is called ""One of the most dashing advances of the human mind into the secrets of the composition of matter on earth and in cosmos""(Kedrow in ""Spectralanalyse"", 1961). The spectral lines proved to be a guide not only to the great world of the outer cosmos, but to the infra-tiny world within the atom. Balmer made the first steps in this direction (the Balmer-lines). The next year Kirchhoff and Bunsen published another memoir in which they announced the finding of another new element, Rubidium""The two investigators advanced, as scientifically established, the law that the bright lines in the spectrum may be taken as a sure sign of the presence of the respective metals. This conclusion was rendered doubtly sure by the discovery in the mineral water of Durkheim, through the spectrum, of two new metals. From the blue and the red lines, by which they were recognized, they were named ""Cæsium"" and ""Rubidium"". While spectrum analysis, as a terrestrial science, was due equally to Kirchhoff and Bunsen, its celestial applications belong to Kirchhoff alone.""(Cajori in ""A History of Physics in its Elementary Branches"", pp. 160 ff).In a letter to Henry Roscoe, with whom Bunsen carried out a long importent series of photochemical researches, Bunsen wrote: ""At present Kirchhoff and I are engaged in a common work which doesn't let us sleep....Kirchhoff has made a wonderful, entirely unexpected discovery in finding the cause of the dark lines in the solar spectrum, and increasing them artificially in the sun's spectrum, and inproducing them in spectra which does not have lines, and in exactly the same position as the corresponding Frauenhofer lines. Thus a means has been found to determine the composition of the sun and fixed stars with the same accuracy as we determine sulfuric acid, chlorine, etc., with our chemical reagents.

The significance of this paper is that Kirchhoff proved with action at a distance that electric disturbances travel along wires of neglible resistance with the velocity of light. He accomplished this with the laws of Newtonian electrodynamics before Maxwell formulated his equations.""The theory of variable currents raised more difficult problems. The law of dynamical interactions between currents had been formulated by Ampere (1826) in the spirit of the concept of action at a distance....The field was still open when Kirchhoff entered it in 1857 with his own general theory of the motion of electricity in conductors (in the paper offered). His first paper, in which he treated linear conductors from the same premises as Weber, turned out to coincide in all essentials with an investigation carried out by Weber shortly before but delayed in publication. Both physicists noticed a remarkable implication of their theory: in a perfectly conducting circuit, oscillating currents could be propagated with a constant velocity, independent of the nature of the conductors, and numerically equal to the velocity of light. Both Weber and Kirchhoff however, pointing to the extreme character of the condition of infinite conductivity, dismissed this result as a mere accidental coincidence.""(DSB VII, p. 380-81).‎

‎First printing of this collection of influential papers within 20th century physics. Klein and Rosseland's paper (ÜBER ZUSAMMENSTÖSE ZWISCHEN ATOMEN UND FREIEN ELEKTRONEN) created an entire new field of physics: Collisions of the second kind. Klein and Rosseland discovered that and electron in an excited state could jump to a lower state without radiation with the released energy being transferred to a free electron as kinetic energy. ""Franck and Hertz had shown how collisions between atoms and free electrons could cause excitation of the atoms, involving the transition of an electron from one stationary state to another of higher energy, the difference being equal to the loss of energy of the free electron. Klein and Rosseland considered the equation as how this would influence the thermal equilibrium between the atomic systems and free electron when Einstein's considerations of 1917 on the statistical equilibrium between blackbody radiation and atoms were used."" (Thorsen. The Penetration of Charged Particles Through Matter. P. 27.)Niels Bohr took a great interest in the paper and his correspondences reveal that he had great expectations regarding the utility of the concept of collisions of the second kind. Ladenburg's paper (DIE QUANTENTHEORETISCHE DEUTUNG DER ZAHL DER DISPERSIONSELEKTRONEN) is the first printing of the first step towards the formulation of a quantum-theoretic interpretation of dispersion (the Ladenburg-Equation). Ladenburg's results were later (1924) generalized by Kramers in his ""The Law of dispersion and Bohr's Theory of Spectra."".‎

‎First appearance of the important paper which constitutes one of the first results obtained from the study of quantum electrodynamics and ""played an important role in discussions of the applicable limits of quantum mechanics to studies of cosmic rays and nuclear physics."" (DSB).""In early 1928 Nishina returned to Copenhagen and worked with Oskar Klein. As a result of their cooperation, the Klein-Nishina formula was completed in October of the same year, before Nishina's return to Japan. In 1923 the quantum (particle) nature of X rays was discovered by Arthur Compton. Nishina had once made an experimental approach to this phenomena at the Cavendish Laboratory. The relation among the increased wavelength of the scattered X rays, the energy of recoiled electrons, and the scattering angle was accounted for by the quantum nature. In 1928 Nishina and Klein calculated the cross section and intensity of the Compton scattered radiation by the use of Dirac's new relativistic quantum mechanics of electrons. They succeeded in a complicated calculation by doing this separately and checking it together. (Nishina also brought this method of calculation with a team back to Japan.)Nishina and Klein searched for the solution of Dirac's wave equation in the case of a free electron (initially at rest) in the field of a plane electromagnetic wave."" (DSB).The Klein-Nishina was one of the first results obtained from the study of quantum electrodynamics. Consideration of relativistic and quantum mechanical effects allowed the development of an accurate equation for the scattering of radiation from a target electron. Before this derivation, the electron cross section had been classically derived by the British physicist and discoverer of the electron, J.J. Thomson. However, scattering experiments showed significant deviations from the results predicted by the Thomson cross section. Further scattering experiments agreed perfectly with the predictions of the Klein-Nishina formula.‎
