Archimedes Manuscript under X-ray Vision"

An informal discussion with

The privately owned parchment document known as the Archimedes Palimpsest is the oldest and unique source of several of the great Greek’s treatises. Dr. Uwe Bergmann, a physicist at the Stanford Synchrotron Radiation Laboratory, recently uncovered missing writings with the help of an intense x-ray beam. The x-ray images revealed writings from some of Archimedes’ most important works covered by mold stains, biblical texts and forgeries. Dr. Bergmann will take us on the fascinating journey of a 1000 year old parchment from its origin in the Mediterranean city of Constantinople to a particle accelerator in Menlo Park.  Uwe Bergmann was born in Karlsruhe, Germany, where he also did his undergraduate work. He received the German 'Diplom' in Hamburg and Ph.D. in physics at Stony Brook University. Since 1990 he has been an enthusiastic user of synchrotron radiation and has worked at numerous synchrotron facilities around the world. Bergmann joined SLAC in March 2003, where his research interests focus on the development and application of novel synchrotron based x-ray techniques.
