Nobel Prize Winners Add GPS Accuracy
Two American scientists and a German won the Nobel Prize in physics Tuesday for optics research that is improving the accuracy of such precision instruments as GPS locators, atomic clocks and navigation systems.
Americans John L. Hall and Roy J. Glauber shared the prize with Theodor W. Haensch of Germany. Glauber, 80, of Harvard University, took half of the $1.3 million award for showing how the quantum nature of light can affect its behavior. His insights led to the work of Hall, 71, a professor at the University of Colorado, and Haensch, 63, of the Ludwig-Maximilian-Universitaet in Munich. Hall and Haensch will share the other half of the prize.
