‎First printing of this classic paper on ""thermal respiration"" in which Reynolds explains how some of the movements of the vanes in Crookes' Radiometer can be accounted for. ""The correct solution to the problem (the problem of finding the cause of the movement of the vanes in Crooke's radiometer) was provided qualitatively by Osborne Reynolds, better remembered for the ""Reynolds number"". Early in 1879 Reynolds submitted a paper to the Royal Society in which he considered what he called ""thermal transpiration"", and also discussed the theory of the radiometer. By ""thermal transpiration"", Reynolds meant the flow of gas through porous plates caused by a temperature difference on the two sides of the plates. If the gas is initially at the same pressure on the two sides, it flows from the colder to the hotter side, resulting in a higher pressure on the hotter side if the plates cannot move. Equilibrium is reached when the ratio of pressures on either side is the square root of the ratio of absolute temperatures. This counterintuitive result is due to tangential forces between the gas molecules and the sides of the narrow pores in the plates. The effect of these thermomolecular forces is very similar to the thermomechanical effects of superfluid liquid helium. This liquid, which lacks all viscosity, will climb the sides of its container towards a warmer region. In fact, this form of liquid helium climbs so quickly up the sides of a thin capillary tube dipped into it, that a fountain is produced at the tube's other end.""(Philip Gibbs).‎

Pp. 370-96"" Pp. 569-585. [Entire volume: (8), 732 pp. + 6 plates.‎

‎First printing of Rutherford and Soddy's seminal paper on the nature of radioactivity, ""the revolutionary theory that radio-activity is a by-product of the transmutation of one form of matter into another."" (PMM 411). The theory ""provided the break with the past that was clearly needed [...] In this great theory of radioactivity which these young men sprung on the learned, timid, rather unbelieving, and, as yet, unquantized world of physics of 1902 and 1903, they unabashedly but forward the idea that some atomic species are subject to spontaneous transmutation."" (PAIS, Inward Bound).They both were awarded the Nobel Prize in Physics for their work within radioactivity. Rutherford and Soddy introduced the expression ""atomic energy"" in this paper, ""not just for the energy released by a radioactive element, but much more generally for the energy locked in any atom"" (Brown et al., Twentieth Century Physics, I, p. 63).""By this time Rutherford had recognized the need for skilled chemical assistance in his radioactivity investigations and had secured the services of a young chemistry demonstrator at McGill, Frederick Soddy. Together they removed most of the activity from a thorium compound, calling the active matter thorium X"" but they too found that the X product lost its activity and that the thorium recovered its original level in a few weeks. Had Becquerel's similar finding for uranium not been immediately at hand, they might have searched for errors in their work. In early 1902, however, they began to plot the activities as a function of time, seeing evidence of a fundamental relationship in the equality of the time for thorium X to decay to half value and thorium to double in activity.This work led directly to Rutherford's greatest achievement at McGill, for with Soddy he advanced the still-accepted explanation of radioactivity. Their iconoclastic theory, variously called transformation, transmutation, and disintegration, first appeared in 1902 and was refined in the following year. Although alchemy had long been exorcised from scientific chemistry, they declared that ""radioactivity is at once an atomic phenomenon and the accompaniment of a chemical change in which new kinds of matter are produced."" The radioactive atoms decay, they argued, each decay signifying the transmutation of a parent into a daughter element, and each type of atom undergoing its transformation in a characteristic period. This insight set the course for their next several years of research, for the task was then to order all the known radioelements into decay series and to search for additional members of these families.""

‎The Nature of the alpha Particle.‎

‎Manchester, 1909. 8vo. Contemp. full cloth. Orig. printed paper label on spine (a bit chipped). In: ""Memoirs and Proceedings of the Manchester Literary & Phlosophical Society. (Manchester Memoirs.). Volume LIII. (1908-09). Entire volume offered. The volume contains 24 papers, all with seperate pagination. Rutherford's paper: pp. 1-3.‎

‎First printing of the paper which Rutherford and Royds gave the final proof that the alpha particle are atoms of helium. The present paper was read on November 3rd 1908 and published on the 19th. It was reprinted in Philosophical Magazine and that paper is dated November 13, 1908 and published February 1909.""After nearly a decade of labor, Rutherford was finally prepared to state... what the alpha particle really was ""We may conclude that an alpha-particle is a helium atom, or, to be more precise, the alpha-particle, after it has lost its positive charge, is a helium atom"". In a paper together with Royds, completed in November 1908, he was even more emphatic: ""We can conclude with certainty... that the alpha-particle is a helium atom... They had shown that a discharge sent through a volume in which alpha-particles from radium had been collected produced the characteristic helium spectrum !""(Pais ""Inward Bound"", p. 61).""Rutherford’s early conviction that the alpha particle was a doubly charged helium atom, but he had not succeeded in proving that belief. In 1908 he and Geiger were able to fire alpha particles into an evacuated tube containing a central, charged wire and to record single events. Ionization by collision, a process studied by Rutherford’s former colleague at Cambridge, J. S. E. Townsend, caused a magnification of the single particle’s charge sufficient to give the electrometer a measurable ""kick."" By this means they were able to count, for the first time accurately and directly, the number of alpha particles emitted per second from a gram of radium.This experiment enabled Rutherford and Geiger to confirm that every alpha particle causes a faint but discrete flash when it strikes a luminescent zinc sulfide screen, and thus led directly to the widespread method of scintillation counting. It was also the origin of the electrical and electronic methods of particle counting in which Geiger later pioneered. But at this time the scintillation technique, now proved reliable, was more convenient. This counting work also led Rutherford and Geiger to the most accurate value of the fundamental electric charge e before Millikan performed his oil-drop experiment. They measured the total charge from a radium source and divided it by the number of alphas counted to obtain the charge per particle. Since this figure was about twice the previous values of e. they concluded that the alpha was indeed helium with a double charge. But Rutherford still desired decisive, direct proof"" and here his skilled glassblower came to his aid. Otto Baumbach in 1908 was able to construct glass tubes thin enough to be transparent to the rapidly moving alpha particles yet capable of containing a gas. Such a tube was filled with emanation and was placed within a larger tube made of thicker glass. In time, alpha particles from the decaying emanation penetrated into and were trapped in the space between inner and outer tubes: and when ROYDS SPARKED THE MATERIAL IN THIS SPACE, THEY SAW THE SPECTRUM OF HELIUM."" (DSB).The volume contains 2 other importent papers by Rutherford 1. ""Some Properties of the Radium Emanations"" (issued Nov. 19th, 1908) and 2. together withY.

‎First appearance of this seminal paper which contains Rutherford's discovery of artificial transmutation. He here discovered, that the atomic nucleus (discovered by him in 1911) itself had a structure, when, by bombarding nitrogen with alpha particles, he produced THE FIRST ARTIFICIAL TRANSFORMATION OF AN ELEMENT INTO ANOTHER, and what was left after the bombardment had to be those of oxygen atoms. - Thus thus began the age of nuclear physics.""Rutherford was .. the first man ever to change one element into another as a result of the manipulations of his own hands. He had achieved the dream of the alchemists. He had also demonstrated the first man-made ""nuclear reaction"". By 1924 Rutherford had managed to knock protons out of the nuclei of most of the lighter elements."" (Asimov).""A few years before, Marsden had noticed scintillations on a screen placed far beyond the range of alpha particles when these particles were allowed to bombard hydrogen. Rutherford repeated the experiment and showed that the scintillations were caused by hydrogen nuclei or protons. This was easily understood, but when he substituted nitrogen for the hydrogen, he saw the same proton flashes. The explanation he gave in 1919 stands beside the transformation theory of radioactivity and the nuclear atom as one of Rutherford’s most important discoveries. This, he said, was a case of artificial disintegration of an element. Unstable, or radioactive, atoms disintegrated spontaneously"" but here a stable nucleus was disrupted by the alpha particle, and a proton was one of the pieces broken off."" (DSB).PMM 411.‎
