In October, physicists John L. Hall, Roy J. Glauber and Theodor W. Hnsch joined more than 200 Sigma Xi members who have received the Nobel Prize.
They won the prize for their work in applying modern quantum physics to the study of optics. Engineers have used their observations to improve lasers, Global Positioning System technology and other instruments.
Glauber, 80, of Harvard University, took half of the 2005 Nobel in physics for showing how the particle nature of light affects its behavior under certain circumstances.
Those conditions are rarely observed in nature, but they are often relevant in sophisticated optical instruments.
Glauber was elected to Sigma Xi in 1944 at Harvard University.
Hall, 71, of the University of Colorado, and Hansch, 63, of the Ludwig-Maximilian-Universitaet in Munich, won "for their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique."
The technique makes it possible to carry out studies of, for example, the stability of the constants of nature over time and to develop extremely accurate clocks and improved GPS technology.
Hall was elected to Sigma Xi in 1960 at the Carnegie Institute of Technology, and Hnsch, in 1971 at Stanford University.
Hall works for JlLA, an institute run by the University of Colorado and the National Institute of Standards and Technology.
