The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...

... Maxim was one of the leading analysts of Russia space activities, those who set the basis for the open independent analysis of then-Soviet space program. q In the early 1990s the small blue paperback book became a real breakthrough. In the time being, almost everything is allowed; in that time, even the title of the book - The Military . ... I believe that to open Maxim's files and archives for the experts and Russian space program enthusiasts would be a best thing we can do in memoriam. ...
