"On the Charge carried by the alpha- and beta-Rays of Radium" The London, Edinburgh, and Dublin Philosophical Magazine; London, Taylor & Francis, Volume X, Sixth Series, July-December 1905

+++Rutherford on Radiation, Brace on Ether-Drift, and the Kelvin Model of the Atom (1905)+++ The London, Edinburgh, and Dublin Philosophical Magazine; London, Taylor & Francis, Volume X, Sixth Series, July-December 1905; vii, 712pp, with 13 plates (some folding). Bound in dark blue cloth, with very heavily (and professionally) reinforced hinges, making this thick book stout enough top be read held in one hand. There is a remnant of a call card and a library name on a slip of paper half-attached to the first page of the table of contents, though this is the only mark I can find showing the history of ownership of the book. This is a VERY GOOD copy of this volume.+++ There are many strong contributions in this volume relating to radioactivity, including: Ernest Rutherford, "On the Charge carried by the alpha- and beta-Rays of Radium", pp 193-208; these first two Rutherford papers referenced in Charles Bailey's "Early Atomic Models - From Mechanical to Quantum (1904-1913)" Ernest Rutherford, "On Slow transformation Products of Radium", pp 290-306. Ernest Rutherford, "On Some Properties of the alpha-Rays from Radium", pp 160-163. ("When Pierre and Marie Curie, with Gustave Bémont, announced later in 1898 the discovery of two new radioactive elements, polonium and radium, world scientific attention finally crystallized. Rutherford did not jump on this bandwagon.in fact, that his own work alone would have served the same purpose as radium in creating the science of radioactivity.for within a short time Rutherford, not Becquerel or the Curies, was the dominant figure in the field. He began by examining the Becquerel rays uranium. Indeed, until about 1904 the emissions received far more attention than the emitters. Passage of the radiation through foils revealed one type that was easily absorbed and another with greater penetrating ability; these Rutherford named alpha and beta, for simplicity.--Dictionary of Scientific Biography, vol 12, pg 27. W. H. Bragg, R. Kleeman, "On the α particles of radium, and their loss of range in passing through various atoms and molecules", pp 318-340. (This is #75 / 100 top-cited articles in the Phil Mag from 1900-2106, and one of only 13 pre-1920 articles, and there being #9 in that subgroup.) D.B. Brace, "The Negative Results of Second and Third Order Tests of the "Aether Drift," and Possible First Order Methods", pp 71-80 (an early paper on the electrodynamics of moving bodies by Brace, who took his Ph.D. under von Helmholtz and was VP AAAS). "Rayleigh made experiments in which he failed to find the predicted effect, but his work was not quite accurate enough to be conclusive. Brace pointed this out and reconducted the investigation in his own laboratory, establishing beyond a doubt the absence of double refraction caused by movement of the refracting medium through the ether. This did not disprove the contraction hypothesis, but Brace at first believed that it did. Joseph Larmor showed that double refraction need not result from Lorentz contraction if matter is composed of electrically charged particles that contract in the same proportion as large bodies; he thus saved the Lorentz hypothesis and gave the electron its status as a fundamental particle of matter." DSB, vol 2, pg 383. Remarkable work especially considering that when he landed in Nebraska a few years earlier the physics lab had no equipment "whatsoever" and existed in part of a room in the chemistry dept.
