Aggiungi al carrelloHardcover. Condizione: Very Good. 1st Edition. Two parts comprising text volume and atlas with plates. Text volume: 4to (310 x 238 mm), Plate volume: oblong folio (340 x 540 mm). Text volume: [4], 42, xv [1] pp. and lithographed frontispiece. Atlas volume: title sheet and 6 sheets of lithographed plates. Original publisher's printed wrappers (front wrapper of atlas stained, with minor paper repair and tanning). Housed in a custom-made cassette. Plates unbound as issued. Text and plates with little age-toning only, the text volume very crisp and clean, the title sheet of the atlas with unobtrusive brown stain at foot. An exceptional, unsophisticated copy. ---- DSB I, p. 166; Norman 56; Honeyman 096. - RARE FIRST EDITION. The classic work on the solar system in which Angström demonstrated the presence of hydrogen and a number of other elements in the sun. Solar spectroscopy provided the first scientific evidence (other than the occasional meteorite) that the elements known on earth are also present elsewhere in the universe. Angström also established a scale of wave-lengths for measuring spectral lines, replacing Kirchoff's arbitrary scale. Angström's system was based on a unit of one ten millionth of a millimetre, named the "Angström unit" in his honor. He conducted detailed measurements of more than 1000 spectral lines. The plates are in effect a map of the solar spectrum, and show the radiation of the solar spectrum ranging from 0.8 to 0.4 micron and from red to purple colour. It identifies the particular lines of manganese, aluminium and titanium. The lithographic plates are after R. Thalén (1827-1905), Angström's laboratory assistant. The lithographic frontispiece to the text volume is showing Angström's spectrometer. Some copies have a further 2 plates showing the ultraviolet spectrum, but the Norman, Gedeon, Green and Honeyman copies - like the present copy - do not have these. - Visit our website to see more images!

Aggiungi al carrelloSoft cover. First edition. A FOUNDING WORK OF SPECTROSCOPY. First edition, a very fine copy in unrestored original printed wrappers, and rare thus, of one of the founding works of spectroscopy in which Ångström demonstrated the presence of hydrogen and a number of other elements in the sun; the atlas contains his great map of the solar spectrum. Since the plates of the atlas were simply laid in to the printed wrappers (and not sewn), the wrappers were often lost or damaged; it is rare to find these wrappers present and in fine condition as in our copy. In his Nobel Prize lecture, Arthur Schawlow (who shared the 1981 prize for his contributions to the development of laser spectroscopy) wrote: "Fraunhofer had charted the dark lines in the spectrum of the Sun, and had measured their wavelengths. But it was Ångström who first identified some of these lines as corresponding to bright lines emitted by particular substances Most importantly, he showed the red line of hydrogen." "After 1861 Ångström intensively studied the spectrum of the sun, noticing the presence of hydrogen in the solar atmosphere and confirming the probable existence there of a number of other elements. In 1868 he published the monumental Recherches sur le Spectre Solaire, which contained an atlas of the solar spectrum with measurements of the wavelengths of approximately a thousand lines determined by the use of diffraction gratings. Ångström expressed his results in units of one ten-millionth of a millimetre a unit of length that has been named the Ångström unit in his honor. In order to have a precise basis for the new science of spectroscopy, accepted standards were needed In 1861 Kirchhoff made a map of the solar spectrum and labeled lines with the corresponding scale readings of his own prismatic instrument. These rapidly became the almost universally accepted manner of designating spectral lines, but they were inconvenient because each observer had to correlate his own readings with those of the arbitrary Kirchhoff scale. Ångström's wavelength measurements provided a more precise and convenient reference and, after 1868, became a competing authoritative standard" (DSB). Spectroscopic studies were crucial to Max Planck's explanation of blackbody radiation, Albert Einstein's explanation of the photoelectric effect, and Niels Bohr's explanation of atomic structure. Spectra are used to detect, identify and quantify information about the chemical composition of substances in the laboratory, as well as in astronomy where they enable the determination of the chemical composition and physical properties of celestial objects. "By the time that Ångström began his studies on spectral analysis at Uppsala, a fair amount of information was known, more experimentally than theoretically, about the solar spectrum. Optics had become a subject of intensive study during the first half of the nineteenth century, but there was little interest in identifying the cause of the lines on the spectra and in appreciating their structural implications no significant progress had been made in the eighteenth century since Newton's classic investigations on sunlight and his experiments with prisms and reflecting telescopes Newton failed to note that the light from the sun is not perfectly homogeneous; instead it was [William Hyde] Wollaston (1766-1828) who first discovered this effect by observing the rays of sunlight admitted through a narrow slit in a window blind. Wollaston's initial observation of seven dark lines, followed by [Joseph von] Fraunhofer's work, which included a greater number of lines in the solar spectrum, lies at the root of all subsequent works, including that of Ångström. The studies of these pioneers had shown that whereas sunlight differed from ordinary white light in having a spectrum of dark lines, colored light differed from the same white light in having a spectrum in which bright lines could be seen. Ångström familiarized himself with all of this work " (Reif-Acherman). "By the time he was appointed regular professor of physics, in 1858, Ångström had already published one of his two most famous contributions to the new scientific field of spectroscopy. The paper Optical Researches was published in Swedish in 1853 and in English and German two tears later. In it Ångström presented, in an unsystematic fashion, a number of experimental results concerning the absorption of light from electrical sparks in gases. He also made theoretical interpretations indicating, among other things, that gases absorb light of the same wavelengths that they emit when heated, and suggesting, somewhat obliquely, that the Fraunhofer lines could be explained in this way. "During the priority disputes that followed Gustav Kirchhoff's publication of the law of absorption and the explanation of the Fraunhofer lines [and his map of the solar spectrum] around 1860, Ångström and his collaborator at Uppsala University, Robert Thalén (1827-1905), vigorously defended the Swede's priority. Their claims were to some extent recognized also in Britain when the Royal Society elected Ångström foreign member in 1870 and awarded him the Rumford Medal two years later. These honors were also given in recognition of Ångström's other important spectroscopic work, an atlas of the solar spectrum published in 1868" (Biographical Encyclopedia of Astronomers). "In 1868, Ångström published his most important work, 'Recherches sur le Spectre Solaire', in Uppsala. The essay, a compendium of all of his experiments, received considerable international attention and became the standard of spectroscopy for at least a quarter of a century Because of its considerable greater dispersive power [i.e., that of Ångström's spectrometer], the information included in Ångström's map surpassed the information found in Kirchhoff's map, and the number of visible bands rose accordingly Several dark bands on Kirchhoff's map resolved themselves into arrays of tightly packed lines The measurements give the.
