There are many natural phenomena in California that can be explained by classical physics. Lars Bildsten and KITP postdoc Phil Arras have introduced a new undergraduate physics course at UCSB that teaches fluid mechanics and its naturally occurring applications. In this Chalk Talk, Lars and Phil will show you a few of the more exciting examples they have uncovered! Lars Bildsten is a permanent member at KITP and professor in the Physics Department at U.C. Santa Barbara. He received his PhD in theoretical physics from Cornell University in 1991, and was at Caltech as the Lee A. DuBridge Research Fellow in Theoretical Astrophysics until 1995, when he was appointed assistant professor in both the Physics and Astronomy departments at U.C. Berkeley. Phil Arras is a postdoctoral researcher at KITP. He received his PhD in physics from Cornell University in 1999 and was a researcher at the Canadian Institute for Theoretical Astrophysics until 2002, when he moved to KITP as an NSF Astronomy and Astrophysics Postdoctoral Fellow. http://online.kitp.ucsb.edu/online/friends/bildsten1/ Wed, 01 Feb 2006 18:30:00 -0800 54:12 http://online.kitp.ucsb.edu/online/friends/morrison/ David Morrison, KITP & Duke University (Dr. David Morrison, KITP & Duke University) Dr. David Morrison, KITP & Duke University http://online.kitp.ucsb.edu/online/friends/morrison/ Thu, 03 Nov 2005 18:30:00 -0800 1:00:00 http://online.kitp.ucsb.edu/online/friends/zee/ Anthony Zee, KITP (Dr. Anthony Zee, KITP) Dr. Anthony Zee, KITP Dr. Anthony Zee, KITP Dr. Anthony Zee, KITP (Wed, 08 Jun 2005 18:15) Contrary to what Watson and Crick enunciated in their "central dogma" soon after they figured out the genetic code, biologists in recent years have elucidated the central role played by RNA. Indeed, current speculations on the origin of life generally place RNA before DNA. Biological functions depend largely on the shape of the molecules involved and thus understanding how RNA folds into the correct shape has emerged as an important problem in biology. Clearly, shape and topology (the branch of mathematics concerned with the difference between a ball and a doughnut) are relevant here. Given this fascinating interplay between mathematics and physics, the subject encourages an inter-disciplinary approach, requiring the efforts of theoretical physicists, mathematicians, as well as that of biochemists. I will describe an approach using quantum field theories with its built in topological character. This talk will not presuppose any knowledge of quantum field theory and mathematics. Instead I will use color (literally) to explain certain topological properties of Feynman diagrams. http://online.kitp.ucsb.edu/online/friends/zee/ Wed, 08 Jun 2005 18:15:00 -0700 1:21:00 http://online.kitp.ucsb.edu/online/friends/polchinski/ Joe Polchinski, KITP (Dr. Joe Polchinski, KITP) Dr. Joe Polchinski, KITP Dr. Joe Polchinski, KITP Dr. Joe Polchinski, KITP (Wed, 21 Apr 2004 17:00) For some time, theoretical physicists have been exploring the idea that the basic building blocks of nature are strings, tiny vibrating loops. Although there are many theoretical arguments in support of this idea, the very small size of the strings has made experimental tests difficult. Under certain conditions, strings produced shortly after the big bang will grow along with the expanding universe, so that today they would be of cosmic size. Such cosmic strings can be detected in various ways. In particular they emit intense gravitational waves, and could be the brightest objects visible in the new era of gravitational wave astronomy. http://online.kitp.ucsb.edu/online/friends/polchinski/ Wed, 21 Apr 2004 17:00:00 -0700 1:08:19 http://online.kitp.ucsb.edu/online/friends/bildsten/ Lars Bildsten, KITP (Dr. Lars Bildsten, KITP) Dr. Lars Bildsten, KITP http://online.kitp.ucsb.edu/online/friends/bildsten/ Thu, 17 Jul 2003 18:15:00 -0700 1:14:49
