Lecture Background

The recipient of the 2005 Nobel Prize in Physics celebrates the events that created one of science's most powerful and versatile tools. A mixture of curiosity-driven research and luck created the “Optical Frequency Comb”, which uses lasers to measure the frequency of light released from atoms and molecules with exquisite precision. John Hall reveals unexpected and useful applications that can measure both time and distance more accurately than ever before.

This lecture was held at Chongqing University, China, on Thursday, 15 October 2009. Professor Hall's lecture and other videos from his two day visit are now online.
