How did Ludwig Prandtl suggest the condition known as the Prandtl Condition?
Ludwig Prandtl Ludwig Prandtl (4 February 1875 – 15 August 1953) was a German engineer. He was a pioneer in the development of rigorous systematic mathematical analyses which he used for underlying the science of aerodynamics, which have come to form the basis of the applied science of aeronautical engineering. In the 1920s he developed the mathematical basis for the fundamental principles of subsonic aerodynamics in particular; and in general up to and including transonic velocities. His studies identified the boundary layer, thin-airfoils, and lifting-line theories. The Prandtl number was named after him.
Psychogenesis of Mental Disease Psychogenesis of Mental Disease is Volume 3 in "The Collected Works of C. G. Jung", a series of books published by Princeton University Press in the U.S. and Routledge & Kegan Paul in the U.K. It was edited and translated from German by Sir Herbert Read, R.F.C. Hull and Gerhard Adler. The book shows the development of Jung's thoughts about the nature of mental illness, and established him as a pioneer and scientific contributor to psychiatry. It contains "On the Psychology of Dementia Praecox" (1907), which Abraham Brill described as "indispensable for every student of psychiatry". Also included are nine other papers in psychiatry, from "The Content of the Psychoses," (1908), to two papers from 1956 and 1958, discussing Jung's conclusions after long experience in the psychotherapy of schizophrenia.
