The Nobel prize for physics this year has been awarded to:
(1/2 of the prize) Roy J. Glauber for "for his contribution to the quantum theory of optical coherence",
(1/4 of the prize each) John L. Hall and Theodor W. Hänsch "for their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique."
Many hearty congratulations to them!
Update: the BBC have a short story on the award, and there are also comments from Lubos Motl and Peter Woit.
