Ludwig Waldmann (June 8, 1913 in Fürth – February 9, 1980) was a German physicist who specialized in transport phenomena in gases. He derived the Waldmann-Snider equation.〔Hess, 2003〕 ==Career== Waldmann completed his Ph.D.〔(Ludwig Waldmann (Mathematics Genealogy Project) ) – Waldman’s thesis title: ''Über eine Verallgemeinerung der Boltzmannschen Abzählungsmethode auf das van der Waalsche Gas''〕 under Arnold Sommerfeld at the University of Munich in 1938. He was Sommerfeld’s assistant, at the Institute of Theoretical Physics, from 1937 – 1939. Waldman had been the scribe〔A scribe took class notes during lectures and wrote them up for the professor, and, sometimes, the student library. While this task required considerable effort and skill, as well as understanding of the subject matter, it also afforded the scribe with close and frequent contact with the professor – a considerable intellectual benefit to the capable student.〕 for Sommerfeld’s optics course in 1934, and Waldmann’s careful record of the lectures were the basis for Sommerfeld’s book ''Optics - Lectures on Theoretical Physics Volume IV''.〔Sommerfeld, 1964, p. vii.〕 After being granted his Ph.D. in 1938, his career spanned four decades with many publications to his name (at least 99): 〔 *1939 – 1943: Institute of Physical Chemistry, Munich *1943 – 1954: Kaiser-Wilhelm-Gesellschaft and the Max-Planck Institute (MPI) for Chemistry (In 1948 the Kaiser Wilhelm Gesellschaft facilities were named after Max Planck.) * *1943 – 1944: in Berlin * *1944 – 1949: in Tailfingen * *1949 – 1954: in Mainz *1954 – 1963: Fellow (wissenschaftliches Mitglied) of MPI, Mainz *1963 – 1978: Chair for Theoretical Physics, University of Erlangen-Nürenberg * *1964/1965 Academic Year: Visiting professor, Department of Chemical Engineering, University of Minnesota * *1974: Molecular Physics Group, University of Leiden *1978: Retired Waldmann, for many years, was the chairman of the Thermodynamics and Statistical Physics section of the German Physical Society. He was also a corresponding member of the International Union of Pure and Applied Physics and a member of the Bavarian Academy of Sciences.〔 Waldmann’s technical contributions were in the areas of kinetic theory of molecular gases, transport phenomena in gases and liquids, and isotope separation. The venerable ''Handbuch der Physik'' published〔Cited in Hess, 2003: Flügge, Siegfried ''Handbuch der Physik'' 12 295 – 514 (1958)〕 his 220-page article “Transporterscheinungen in Gasen von mittlerem Druck” – a chapter in the article conveyed the then new quantum mechanics version of the Boltzmann equation, which later became known as the Waldmann-Snider equation. The original Waldmann publications on the equation appeared in the literature in 1957 and 1958. Independently, R. F. Snider, a Canadian, published the same kinetic equation in 1960.〔 This equation provided the framework for the interpretation of the Senftleben-Beenakker effect. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ludwig Waldmann」の詳細全文を読む スポンサード リンク
