... Свет: остановка по требованию? ... Более мощное "управляющее поле" (свет с правой циркулярной поляризацией) делает возможным распространение в среде на порядок более слабого "сигнального поля" (упоминавшийся выше импульс, свет с левой циркулярной поляризацией), скорость распространения "сигнального импульса" при этом существенно уменьшается. ... Когда часть импульса (I) уже покинула кювету, управляющее поле выключают и из кюветы ничего не выходит до тех пор, пока управляющее поле не включат вновь. ...

... Evgueni Il'ichev , Doctor of Sciences, IPHT, Jena, Germany . ... In the case of d -wave, due to the sign change of the order parameter associated with this symmetry, strong deviations from the standard sinusoidal dependence have been predicted for the current-phase relations of various configurations of Josephson junctions employing such unconventional superconductors. ... The idea of " p -contact" is connected with unconventional order parameter symmetry for high-T c superconductors. ...

VIEW OUT OF THE WINDOW FROM ARIZONE, USA . ... Our whole class was excited to share with you what we see when we look out our window here, in Chandler, Arizona. Our classroom has no windows, so we decided to go outside on February 2, 1998, and describe to you what we see. You look out across the desert and you see endless roads and it sees almost as if you are in a dream. It's cold; about 65 degrees F (cold for Chandler, anyway) and there has been a touch of fog this morning. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
