See, that really doesn't tell me anything. I think a bit more specific info would help me and maybe a few other folks who haven't ventured into the Linux world.
On my computer video doesn't play well. It lags badly or it's pink and orange. I tried a lots of media players, got codecs and googled the problem with no success.Is it just the video card? Some other problem with my PC? Something I should install?
Well, you can't literally freeze photons, but they do use extremely low temperatures. At least the one I know about.
[The light is] "frozen" with the help of two control beams. The light in the control beams interacts with the rubidium atoms to create layers that alternately transmit and reflect the pulse. As the signal tries to propagate through these layers, the photons bounce backwards and forwards between them. As a result, the pulse makes no forward progress - the light is "frozen" in place. The pulse is set free when the control beams are turned off. . . .. . . two groups reported they had stopped light (New Scientist 08/08/01). Lukin was involved in one of these experiments, the other was led by Lene Hau, now at Harvard.Both teams slowed light down by passing it through a gas of atoms. Lukin used hot rubidium atoms, Hau super-cooled sodium.
