... 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. ...

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. ...
