Rutherford's paper: pp. 374-400. Clean and fine.‎


‎First apperance of this famous lecture in which Rutherford predicted the existence of a new constituent of the atomic nucleus and its likely properties. In the lecture Rutherford suggested that ""it may be possible for an electron to combine much more closely with the H-nucleus (than is the case in the ordinary hydrogen atom)... It is the ontentionof the writer to test (this idea)... The existence of such atoms seems almost necessary to explain the building up of heavy elements.""Rutherford's collegue Chadwick made several attempts to detect the neutral particle but none was successful until he learned of experiments by the Joliot-Curies in Paris, in which, they said, extremely penetrating gamma rays were emitted. As he suspected, Chadwick found the rays were not gammas but neutrons: and not long afterward Norman Feather, also at the Cavendish, showed that neutrons were capable of causing nuclear disintegrations. Chadwick gave proof of its existence in 1932.‎

Rutherford's paper: pp. 537-587.‎


‎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.‎

‎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).‎

It was vital that all thermometers scaled according to his system have the same grade of alcohol. Réaumur suggested that the alcohol used in his thermometers be of a type that would dilate 80 degrees - that is, 8 parts in 100 - between the temperature of ice and the temperature at which the alcohol began to boil in an open thermometer tube. Owing to an unfortunate confusion of language in his article on the thermometer, however, nearly everyone believed that 80° on his scale was the temperature of boiling water"" and as a result, when so-called Reaumer thermometers began to be made by the artisans of Paris, they were nearly all scaled linearly with respect to two fiducial points, 0° for ice and 80° for boiling water.""

‎First full exposition of Röntgen's discovery of X-rays, the foundation stones of roentgenology, unveiling a new form of matter and offering a new revolutionary method for medical diagnosis.In order to ensure priority for his discovery, Röntgen first published the two first papers (Erste-Zweite Mittheilung) as offprints from ""Sitzungsberichte der Physikalisch-medicinischen Gesellschaft zu Würtzburg"" in 1895-96, but his discovery only finds its full form in the offered papers, as ""Dritte Mittheilung"" appears here.""Aside from its obvious applications, Roentgen's discovery galvanized the world of physics and led to a rash of further discoveries that so completely overturned the old concepts of the science, that the discovery of X-rays is sometimes considered the first stroke of the Second Scientific Revolution. (The First Scientific Revolution is, of course that which included Galileo and his experiments on falling bodies). Within a matter of months, investigations of X rays led to the discovery of radioactivity by Becquerel....The importence of the discovery was well recognized in its own time. In 1896 Roentgen shared the Rumford Medal with Lenard and in 1901, when Nobel Prizes were set up.the first to be honoured with a Nobel Prize in Physics was Roentgen.""

‎Neue Versuche über die Absorption von Wärme durch Wasserdampf. 2 Parts. (+ Hertz:) Ueber die Beziehungen zwischen den Maxwellschen electrodynamischen Grundgleichungen und den Grundgleichungen der gegnerischen Electrodynamik.‎

‎Leipzig, Johann Ambrosius Barth, 1884. Contemp.hcalf. Raised bands, gilt spine. Spine very slightly rubbed. Small stamp on htitle, title and verso of titlepage.""Annalen der Physik und Chemie. Hrsg. von G. Wiedemann"". Neue Folge Bd. 23. VIII,696 pp. and 8 folded plates. Röntgen's paper: pp. 1-40 a. 259-298, 2 folded plates. - Hertz's paper: pp. 84-103. Clean and fine.‎


‎First printing of Röntgen's early paper on the heat absorption in vapor. ""Having constructed a very sensitive air thermometer, he was able to measure the absorption of heat in water vapor, and his flair for experiment was also shown by his work on the compressibility of liquids and solids.""(DSB XI, p.530).An. HERTZ'S paper: This is a major paper by Hertz in which he gives simple proofs of Maxwell's fundamental equations. ""In 1884, at Kiel, Hertz had already carried out a study of Maxwell's theory. It was a theoretical response to Helmholtz' general problem of deciding between the electrodynamical theories. Whereas Helmholtz had shown that the experimental decision lay with unclosed currents, Hertz showed that a theoretical decision could be made on the basis of predictions for closed currents. Hertz proved that Maxwell's equations were compatible with the physical assumptions shared by all electrodynamical theories and that the equations of the contending theories were not. He concluded that if the choice lay solely between Maxwell's equations and the equations of the other type of theory, then Maxwell's were clearly preferable."" (DSB VI, pp. 344-45).The volume contains also an importent paper by OTTO RICHARD LUMMER his Inauguraldissertation: ""Über eine neue Inteferenzerscheinung an Planparallelen Glasplatten und eine Methode, die Planparallelität solcher Gläser zu prüfen"". Pp. 40-84 a. 1 plate. and ""Ueber eine neue Inteferenzerscheinung."" pp. 513-548. - Also papers by Kundt, Kohlrausch, Weber and others.‎
