Two Americans and German Share Nobel Physics
The 2005 Nobel Prize in Physics has been awarded to two Americans and a German for their work with light and lasers.
Half the prize goes to Roy Glauber of Harvard University, while the other half is shared between John Hall of the University of Colorado and Theodor Hänsch of the Max Planck Institute in Munich.
Glauber has been honored for his theoretic description of the behavior of light particles. Hall and Hänsch share the other half for their development of laser techniques to determine the color of the light of atoms and molecules with extreme precision.
The Royal Swedish Academy of Sciences says their work has made it possible to develop extremely accurate clocks and improved GPS technology.
