PHYSICS:
Quantum Optics Shines in the Photon's Centenary
Adrian Cho
Roy Glauber has won half the 2005 Nobel Prize in physics for mapping out the conceptual connection between assemblages of individual photons and classical waves of light. Theodor Hänsch and John L. Hall share the other half for developing exquisitely precise techniques to manipulate laser light, which is a quantum-mechanical torrent of photons.
