There is a rich history to the question of finding out just where one is on the earth. In the age of sail accurate navigation became a pressing matter of state concern spurring investment in national astronomical observatories and lucrative prizes for solving "the longitude problem.” The key technological hurdle was devoting sufficiently accurate mechanical clocks which could function aboard a ship. The current state of the art in navigation is the familiar GPS system which also relies on clocks, in this case super accurate atomic clocks which gain or lose fractions of a second in a million years. An important technological breakthrough in making current master clocks was developing the ability to cool atoms to extremely low temperatures, much colder than deep space. In this talk, Professor Jones will sketch some of the history of the connection between timekeeping and navigation.

Prof. Jones interest in atomic clocks started when he was an undergraduate at Williams, working with Prof. Stuart Crampton in the hydrogen maser laboratory. He has a Ph.D. in Physics from Stanford University, and has been invited to give a talk at the Williams at Mystic program about the historical connection between timekeeping and navigation.
