Descripción del artículo del vendedor

JANSKY, Karl. “Radio Waves from Outside the Solar System”, on pg 66 appearing in Nature, volume 132, July-December 1933, 1016pp. Beautifully rebound in half leather with linen boards—quite a rich production. Very Fine copy. __+__ “. At the newly established Bell Telephone Laboratories (Bell Labs) in New Jersey, Karl Jansky was assigned the job of investigating the natural sources of radio waves and the noise or static that could interfere with radio voice transmissions. In 1930 Jansky was the first to discover radio waves from space, and he identified the radio waves as coming from the center of the Milky Way (Jansky 1933). This marked the birth of radio astronomy as a new research discipline.”--Werner Marx, “How accurately does Thomas Kuhn's model of paradigm change .”__+__ Jansky: “In a recent paper [“Directional Studies of Atmospherics at High Frequencies”, Proc. Inst. Rad. Eng., 20, 1920; 1932] on the direction of arrival of high-frequency atmospherics, curves were given showing the horizontal component of the direction of arrival of an electromagnetic disturbance, which I termed hiss type atmospherics, plotted against time of day. These curves showed that the horizontal component of the direction of arrival changed nearly 360° in 24 hours and, at the time the paper was written, this component was approximately the same as the azimuth of the sun, leading to the assumption that the source of this disturbance was somehow associated with the sun.”__+__ Bound with: BLACKETT, P.M.S. “The Positive Electron” (pp 117-119); direct evidence for Dirac’s predicted antiparticle. Abstract: “THE discovery of the positive electron arose from the study of cosmic radiation by the cloud method [C.D. Anderson, in several papers, 1932-33, discoverer of the first antiparticle]. Amongst the tracks of the particles of very great energy, associated with cosmic radiation, were found some which differed from the tracks of negative electrons only by being curved by a magnetic field in the opposite direction. Terrestrial sources of positive electrons of lower energy are now also available, since it has been found that they are produced when hard gamma rays are absorbed by matter, and also in certain cases of nuclear transformation. The production of positive electrons in the laboratory is therefore an easy matter.“ And of course many dozens of others.…
