Professor Hornung Receives Honorary Doctorate
Hans G. Hornung, C. L. Kelly Johnson Professor of Aeronautics, Emeritus, has received an Honorary Doctorate from the ETH (Swiss Federal Institute of Technology, Zurich). He was conferred this honor by the Rector of ETH Zurich, Lino Guzzella at a special ceremony in the Hauptgebaeude of the ETH. Professor Hornung was recognized for his outstanding research contributions to gas dynamics of high-speed currents, especially to reflection and stability of shock waves, to the influence of real gas effects and to the laminar-turbulent transition; in addition the prize is meant as an award of his extraordinary ability to be inspiring when passing his knowledge on to his students. The other recipient of this honor was the Astronomer Royal, Sir Martin Rees, Master of Trinity College, Cambridge University. [Learn More] [Caltech Release]
Alumnus Receives 2012 Simons Graduate Fellowships in Theoretical Computer Science
Christopher Beck (BS '09 Computer Science and Mathematics) is a recipient of a 2012 Simons Graduate Fellowship. The fellowships are given to graduate students in theoretical computer science with outstanding track records of research accomplishments. Beck’s work seeks to establish the limits of how efficiently we can solve computational problems. One of his papers studies a popular class of algorithms known as SAT solvers and shows that if their memory is restricted, then they can require exponential running time. Another result concerns how well we can approximately sample from certain distributions when our computation must be small depth, that is, highly parallelizable. Beck and his co-authors showed that even exponentially large bounded depth circuits cannot sample with even exponentially small success from a certain simple distribution.
