First publication of these groundbreaking papers which together constitute the discovery of Automorphic Functions. "Before he was thirty years of age Poincaré became world famous with his epoch-making discovery of the "automorphic functions" of one complex variable or as he called them the "fuchsian" and "kleinean" functions." DSB.These manuscripts written between 28 June and 20 December 1880 show in detail how Poincaré exploited a series of insights to arrive at his first major contribution to mathematics: the discovery of the automorphic functions. In particular the manuscripts corroborate Poincaré's introspective account of this discovery 1908 in which the real key to his discovery is given to be the recognition that the transformations he had used to define Fuchsian functions are identical with those of non-Euclidean geometry. See Walter Poincaré Jules Henri French mathematician and scientist.The idea was to come in an indirect way from the work of his doctoral thesis on differential equations. His results applied only to restricted classes of functions and Poincaré wanted to generalize these results but as a route towards this he looked for a class functions where solutions did not exist. This led him to functions he named Fuchsian functions after Lazarus Fuchs but were later named automorphic functions. First editions and first publications of these epochmaking papers representing the discovery of "automorphic functions" or as Poincaré himself called them the "Fuchsian" and "Kleinian" functions."By 1884 Poincaré published five major papers on automorphic functions in the first five volumes of the new Acta Mathematica. When the first of these was published in the first volume of the new Acta Mathematica Kronecker warned the editor Mittag-Leffler that this immature and obscure article would kill the journal. Guided by the theory of elliptic functions Poincarë invented a new class of automorphic functions. This class was obtained by considering the inverse function of the ratio of two linear independent solutions of an equation. Thus this entire class of linear diffrential equations is solved by the use of these new transcendental functions of Poincaré." Morris Kline.Poincaré explains how he discovered the Automorphic Functions: "For fifteen days I strove to prove that there could not be any functions like those I have since called Fuchsian functions I was then very ignorant; every day I seated myself at my work table stayed an hour or two tried a great number of combinations and reached no results. One evening contrary to my custom I drank black coffee and could not sleep. Ideas rose in crowds; I felt them collide until pairs interlocked so to speak making a stable combination. By the next morning I had established the existence of a Class of Fuchsian functions those which come from hypergeometric series; i had only to write out the results which took but a few hours.the transformations that I had used to define the Fuchsian functions were identical with those of Non-Euclidean geometry." hardcover

RUTHERFORD, ERNEST - NIELS BOHR - CG DARWIN - THE DISCOVERY OF THE 'PROTON'. C GBiblio.com

The Structure of the Atom. Rutherford Darwin: Collision of 'alpha' Particles with Light Atoms. Bohr: On the Effect of Electric and Magnetic Fields on Spectral Lines

191441545London 1914. No wrappers but stiched. All three papers contained in: "Philosophical Magazine" Sixth Series Vol. 27. No. 159. March 1914. The whole issue issue offered =no. 159: pp. 397-540 and 2 plates.Rutherford's paper.pp. 488-498. - Darwin's paper: pp. 499-506. - Bohr's paper: pp. 506-523. All clean and fine. First edition and first printing of all three papers. Rutherford in this paper for the first time identifies the hydrogen nucleus and called it the 'positive electron'. He later called it 'the proton' . In his definitive paper of 1911 he estimated the radius of the nucleus a hundred thousand times smaller than that of an atom. Darwin in his paper offered here gave a more precise measure.In the first lines of the paper Rutherford outlines the content "The present paper and and the accompanying paper by Mr. C. Darwin the second paper offered here deal with certain points in connection with the "nucleus" theory of the atom which were purposely omitted in my first communication on that subject Phil. Mag. May 1911. A brief account is given of the later investigations which have been made to test the theory and of the deductions which can be drawn from them. At the same time a brief statement is given of recent observations on the passage of alpha particles through hydrogen which throw importent light on the dimensions of the nucleus." - Rutherford had studies alpha-particles intensely in the years before 1914 and proved quite conclusively that the individual particle was a helium atom with its electrons removed. The alpha particles were like the positive rays that had been discovered by Goldstein 1886 and now in 1914 the paper offered Rutherford suggested that the simplest positive rays must be those obtained from the hydrogen and that these must be the fundamentall positively-charged particle. He names it a 'positive electron'.Darwin in the paper offered "concluded from the known data:"No force proportional to some power of the distance other than the inverse square can give the dependence the Rutherford scattering cross section on the initial velocity" and he then calculated the distance of closest alpha-particle-nucleus approach.The paper by Niels Bohr relates to "The Stark effect". In 1913 appeared "an importent new discovery: when atomic hydrogen is exposed to a static electrical field its spectral lines split the amount of splitting being proportional to thefield strenght the linear Stark effect. After Rutherford read this news in "Nature" he at once wrote to Bohr:'I think it is rather up to you at the present time to write something on.electric effects.'" A. Pais. Bohrs paper on The Stark effect appeared in 1914 the paper offered here. - Rosenfeld. Niels Bohr' publications No. 10. unknown

Now this ability - primary perception - has been traced even to disconnected cells of our own bodies. The implications and possibilities of that discovery, and the difficult struggle it has had in finding acceptance in the tradition-bound scientific community makes exciting, challenging, mind-expanding reading.
