Karman Theodore von http://www.galcit.caltech.edu/graphics/history/vonKar.jpghttp://maartenrutgers.org/science/turbulence/photos/slow.jpghttp://joas.free.fr/studies/karman/images/presstotturb.jpgTheodore von Kármán (18811963). Professor of Aeronautics 19301949. First Director of GALCIT, 19301949. In 1926 von Kármán was invited to Caltech to give talks on aerodynamics, and review plans for the new wind tunnel. In 1928 he returned to Caltech for an exchange semester, and finally joined the Institute in 1929 as a research associate in aeronautics. In 1930, he was appointed professor of aeronautics and Director of GALCIT. Among his accomplishments were the first computation of drag for a supersonic projectile; application of dimensional analysis to turbulent flow, the log-law and Kármán constant for turbulent boundary layer velocity distribution (law of the wall); fundamental studies on turbulence; the discovery of the similarity law of transonic flow; and the use of stiffened panels in aircraft construction.He spent most of his time in Washington after 1942. Stepped down as director in 1949 and became professor emeritus. In 1962, at age 81, he was awarded the first National Medal of Science, bestowed in a Whitehouse ceremony by President John F. Kennedy. On his characteristic of never declining a lecturing opportunity, he once joked "I can never pass up the opportunity to dominate the conversation for an entire hour."from: http://www.galcit.caltech.edu/history/index.html http://www.lbl.gov/Science-Articles/Research-Review/Highlights/1998/images/CS_flaw_prop.jpghttp://media.nasaexplores.com/lessons/04-011/images/vortex.jpg
