SUMMARY:A brief history of time(keeping): Optical atomic clocks and th
 eir applications\, Chaos & Complex Systems Seminar\, Shimon Kolkowitz\
 , UW Department of Physics
DESCRIPTION:Optical atomic clocks are now the most stable and accurate
  timekeepers in the world\, with fractional accuracies equivalent to n
 either losing nor gaining a second over the entire age of the universe
 . This unprecedented level of metrological precision offers sensitivit
 y to new physics phenomena\, opening the door to exciting and unusual 
 applications. This talk will provide an introduction to how and why ti
 me is measured from a historical perspective\, with an emphasis on the
  recent development of optical atomic clocks and their applications. I
  will discuss recent progress on pushing clocks to even greater levels
  of precision\, as well as prospects for future improvement. Finally\,
  I will give a brief overview of potential future applications of cloc
 ks\, including gravitational wave detection\, tests of general relativ
 ity\, and searches for physics beyond the Standard Model.
