The Peterson public lecture was given on March 3, 2008 by Nobel Laureate Dr. William D. Phillips form NIST/University of Maryland.  He presented a very informative and highly entertaining talk entitled, "Time and Einstein in the 21st Century:  The Coolest Stuff in the Universe" at the K-State Alumni Center.  The audience learned about atomic clocks, the global positioning system and how very cool temperatures can be used to improve the accuracy of atomic clocks.  The cooling of these atoms allows clocks to be made that are accurate to better than a second in 60 million years and allow testing some of the strangest predictions of Einstein's theories of time and space.  Dr. Phillips won the Nobel prize in 1997 for development of methods to cool and trap atoms with laser light. 

The Peterson lecture series is funded by Chester Peterson, Jr. for publicizing and presenting an annual public lecture series on a continuing basis concerning cosmology or quantum mechanics. http://www.phys.ksu.edu/alumni/news/2006/peterson-chet.html
