Prague, August 16, 2006 . ... We can decide to merge the GCVS with automatic surveys now. I have already outlined the difficulties and will give some examples illustrating the problems slightly later. Steve Kawaler's suggestion: 'The GCVS personnel might play a role as a `meta-catalog' - a central `index' of survey-based catalogs of variable stars'. ... If we want to have a good meta-catalog, the difficulties I have mentioned in relation to merging the catalogues still should be considered. ...

... Here is a brief outline of the current theory of the events in the early history of the solar system: . A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. ... The gas cools off enough for the metal, rock and (far enough from the forming star) ice to condense out into tiny particles. (i.e. some of the gas turns back into dust). ... Once the larger of these particles get big enough to have a nontrivial gravity, their growth accelerates. ...
