Hardcover. Condition: Fine. 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 boardsquite 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.

Soft cover. Condition: Fine. 1st Edition. FIRST EDITIONS IN ORIGINAL WRAPPERS of Karl Jansky's ground-breaking papers announcing the discovery of radio astronomy, a new science that has become one of the essential methods for making modern astronomical observations. Working at Bell Labs, Jansky "was given the task of investigating factors that could interfere with radio waves used for long-distance communication. He designed a linear directional antenna, which, mounted on wheels from a Model T Ford, could scan the sky. He indentified all the sources of interference, such as thunderstorms, except for one weak emission. This he found to be unconnected with the Sun and in 1931 he discovered that the radio interference came from the stars. Jansky published his findings in the Proceedings of the Institute of Radio Engineers in December 1932 ['Directional Studies of Atmospherics at High Frequencies'], the date that marks precisely the beginnings of radio astronomy" (Biographical Encyclopedia of Scientists). Jansky's follow-up paper, "Electrical Disturbances Apparently of Extraterrestrial Origin," published in 1933, was equally transformative, articulating "his revolutionary claim that the hiss static seemed to have its origin in our Milky Way galaxy, with a maximum in a direction that pointed close to the galactic center" (American National Biography). "At the age of just twenty-six, Karl Jansky had become the first person to detect and identify radio waves coming from outer space, a truly historic discovery. The true significance of Jansky's breakthrough surpasses even the momentous discovery that the Milky Way emits radio waves. His accomplishment was to establish the science of radio astronomy and to demonstrate that astronomers could learn a huge amount about the universe by looking beyond the narrow band of electromagnetic wavelengths that are visible to the human eye. He announced his result in a paper entitled 'Electrical Disturbances Apparently of Extraterrestrial Origin' (Simon Singh, Big Bang). The third paper in the collection, "Minimum Noise Levels Obtained on Short-Wave Radio Receiving Systems" discusses problems of noise levels and interference in short-wave systems.
