Nobel Prize in Physics: Seeing the Light 130
lidden writes "The Nobel Prize in Physics 2005 has been awarded Roy J. Glauber "for his contribution to the quantum theory of optical coherence". And John L. Hall and Theodor W. Hänsch "for their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique"."

The German wikipedia and the Indonesian one has also three articles. Some of them are still to be considered stubs.
I would like you to invite to translate them into other languages (oops, I forgot Esperanto, there are already articles about them) and to contribute to those articles. We need freely licensed pictures of them and more details about their CV and their work.
Thanks you very much in advance.

My bad. Need more coffee.

With radio we already have much more sophisticated modulation methods. Most "light band" modulation today is basically an automated, binary version of Morse Code, still effectively in the Stone Age. We are currently just barely able to "tune" a light transmitter and receiver. DWDM is nowhere near the spectral density of current radio technology. We cannot do anything with light approaching phase shift modulation, spread spectrum techniques, code division muxing, hell even plain old FM in the "light band" is currently out of reach. While lasers could be compared to classic PLLs, currently they are not even close to being as useful in frequency modulation and demodulation applications.

Germany and America share the nobel prize (Score:2, Informative)
Hall, 71, of Colorado University and Hänsch, 63, of the Max Planck Institute for Quantum Optics and Munich's Ludwig Maximilian University, share the other half of the prize "for their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique".
Hänsch told reporters in Stockholm via telephone that he was at his Munich office when he learned he had won the prize.
"I was speechless and very, very ecstatic," he said. "I'm now trying to get used to the idea.
"I have learned that you don't have to know everything in your field. But you have to know what has previously not been known," he added.

OTOH I did attend a lecture he gave a few years back and I must say that he is one of the worst lecturers I ever had, he handed the lecture off to his assistant half-way through the semester. But maybe he's a better professor in his advanced courses, his group seemed to be fairly happy with him everytime I talked to somebody.

These days we know that mesons are baryons are not fundamental. Remembering the names of the fundamental particles really isn't that hard and it's worth your time:
Six kinds of quarks: up, down, strange, charm, top, bottom
Six kinds of leptons: electron, muon, tau, electron neutrino, muon neutrino, tau neutrino
Force carriers: photon, W+, W-, Z0, gluon
That's it for the standard model. Most people will agree that the graviton should be added to the list of force carriers, although nobody has observed one yet. There's also the Higgs (or possibly a family of Higgs particles), which hopefully the LHC will either observe or disprove. Then you start getting into stranger possibilities like supersymmetry (which is reasonably well supported by theory) and various whack-job theories (which aren't).
Since you never see bare quarks (a subject of last year's Nobel Prize, I believe) it's worthwhile to know some of the more common baryons (for instance, protons and neutrons) and mesons (learn your pions...and maybe kaons). But trying to memorize them all is pretty pointless, as you can have a lot of different combinations of quarks (especially when you start talking about excited states). Check the Particle Data Group (http://pdg.lbl.gov/ [lbl.gov]) if you need to look up info on a particular particle.
