. Quantum clock (atomic clock) - the time measuring device containing quartz generator, controlled by the quantum frequency standard . Atoms play a role of pendulum. The frequency of atoms radiation while the atoms passing from one energy level to another regulates the quantum clock. This frequency is so stable (error 10^-11 - 10^-13) that quantum clocks allow to calculate the time more exactly, then astronomic methods. Back .

. Comment on J0405+3803 . Our image contains a feature of 25 mJy at 14 mas E-NE from the brightest component. It is not visible in the Caltech-Jodrell (CJ) survey image at 5 GHz (Xu et al. 1995) obtained about 6 years earlier. The 1.6 GHz CJ image (Polatidis et al. 1995) does show an extended feature close to the position in question, but somewhat displaced toward west. VLBApls home page . Last modified: 16 Oct 2000
