  • Education of American research astronomers, 1876-1941

    Creator:
    Hall, Robert Dale, 1947-
    Abstract:
    The education (particularly graduate education) of Americans who were active in astronomical research between 1876 and 1941 is assessed for its effectiveness in preparing the astronomers for careers in research. This period contains three dynamic changes: the growth of American astronomy in becoming the world's leading community of astronomers, the...

  • Ionizing radiation and its chemical effects : a historical study of chemical dosimetry (1902-1962)

    Creator:
    Chorzempa, Mary André, Sister
    Abstract:
    Chemical dosimetry developed in response to needs created by developments in the field of high-energy radiation. Shortly after the discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious effects of ionizing radiation were recognized. To guard against the injurious effects of radiation in medical application, dose-measuring methods...

  • The development of the chlorinity-salinity concept in oceanography

    Creator:
    Wallace, William J.
    Abstract:
    This study traces the historical foundations of the concept of constant ionic proportionality and the equation (Salinity [S%₀] = 1.805 Chlorinity [Cl%₀] + 0.030) which has been in general use in oceanography since 1902 until 1969 and which is based upon this constancy, The notion that the constituents present in...

  • The Development of Astronomy in the United States Prior to 1900

    Creator:
    Harburg, William A.
    Abstract:
    From the earliest English colonization to the present day, there has been interest in astronomy in this country. The purpose of this thesis is to show how the science of astronomy developed in America from the earliest observations by educated colonists using imported instruments and publishing in European journals, to...
