‎Über die Integrale linearer Differentialgleichungen mit periodischen Coëfficienten.‎

‎Wien, Karl Gerold's Sohn, 1868. 8vo. Uncut and unopened in orig. printed wrappers. In: ""Sitzungsberichte der kaiserlichen Akademie der Wissenschaften"", 58. Band, 1. Heft - Juni. Pp. (1-) 155 a. 7 plates.(Entire issue offered). Boltzmann's paper: pp. 54-59. Clean and fine.‎

‎First apperance of an importent paper in which Boltzmann from a mathematical point of view defends atomism. ""Throughout his career, even in his works on subjects other than kinetic theory Boltzmann was concerned with the mathematical problems arising from the atomic nature of matter. Thus, an early paper with the title ""Über die Integrale linearer Differentialgleichungen mit periodischcn Koeffizienten"" (1868) turned out to be an investigation of the validity of Cauchy’s theorem on this subject, which is needed to justify the application of the equations for an elastic continuum to a crystalline solid in which the local properties vary periodically from one atom to the next."" (DSB). The issue contains an importent paper by JOHANN JOSEPH LOSCHMIDT ""Ableitung des Potentiales bewegter elektrischer Massen aus dem Potentiale für die Ruhestand"", pp. 7-14, in which he attempted to derive the Weber-Ampère law from that of Coulomb, and, in accordance with Kirchhoff, to derive Ohm’s law from hydrodynamic flow laws, analogous to Poiseuille’s law.‎

‎First appearance of an importent paper in which Boltzmann followed up his theoretically confirmation of Stefan's experimental findings - the ""Stefan-Boltzmann law"" - by combining the Second Law of Thermodynamics with the theory of the pressure of radiation.‎

‎First appearance of this importent paper in which Boltzmann uses the second law of thermodynamics and Maxwell's electromagnetic theory to derive theoretically, based on Stefan's experimental observations, the proportionality of the radiation emitted from a body and the fourth power of the temperature of the body in Kelvin units. ""The law show a possible connection between thermodynamics and electromagnetism that was exploited in the later quantum theory. In the 1920s it was applied by Edington and others in explaining the equilibrium of stellar atmospheres.""(DSB II, p. 266).""The law states that the total energy radiated per unit surface area of a black body per unit time (known variously as the black-body irradiance, energy flux density, radiant flux, or the emissive power), is directly proportional to the fourth power of the black body's thermodynamic temperature T (also called absolute temperature).The Stefan Boltzmann law was experimentally discovered in the year 1879 by Josef Stefan and deduced 1884 by Ludwig Boltzmann theoretically by thermodynamic considerations from the classical electromagnetic theory of the radiation. In the year 1900, thus 21 years after the Stefan Boltzmann law, discovered Max Planck the Planck radiation law designated after it, from which the Stefan Boltzmann law follows simply by integration over all directions and wavelengths. The Planck radiation law could attribute the Stefan Boltzmann constant also for the first time with the introduction of the quantum of action h to fundamental natural constants.""Parkinson ""Breakthroughs"" 1883 P. ‎

‎First appearance of this classic study of the tapeworm (Taenia), being the first accurate description of the Proglottids.""In 1741 he began to study reproduction by fusion and the regeneration of lost parts in the freshwater hydra and other animals. The following year he discovered that the respiration of caterpillars and butterflies is performed by pores, to which the name of stigmata has since been given. He also studied tapeworms. These investigations earned him a membership of the Royal Society of London in 1743, the same year he became a doctor of laws.""""Bonnet is considered one of the fathers of modern biology. He is distinguished for both his experimental research and his philosophy, which exerted a profound influence upon the naturalists of the eighteenth and nineteenth centuries. "" (D.S.B.
