... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

The Solar spots - are the dark formations on the Sun's disk. ... The greatest observed spot is 100 thousand kilomiters. The spots are the places of the magnetic fields' getting out to the solar atmosphere. ... That's why they look so dark . ... The Solar convection zone is the layer with the thickness of 150 - 200 thousand kilomiters, situated under the photosphere; the substance of this layer being in convectional movement transformes the energy from inside the Sun's to its surface. ...

... Up: FITS-Flexible Image Transport System . ... We have therefore constructed a relational database schema which describes FITS keywords, and have implemented it using Sybase. ... This generalization led swiftly to the use of the ``Memes'' database to document itself, since the fields (columns) of a database table are memes with a large subset of the attributes of a FITS keyword (such as name, datatype, semantics, etc.) ... There are many practical applications for these abilities (see Table 1). ...

It was during "sharing" time in my first week as a teacher's aide at Sunset View Elementary School in San Diego. ... So how can we get our school teachers to know more about science? One approach is to provide science enrichment programs for current and prospective teachers, and many such programs have had success. But there's a second approach that deserves far more attention than it has received: providing opportunities for scientists to become classroom teachers. ...
