It is Friday night and Dr. J's classroom is full of eager young
students. Yes, it's the weekly meeting of the Wizards of Oz, a club
for bright preteens interested in science. This particular night is
even more special because new members will be officially received
into the club. Dr. J had been attracted to the group over a year
ago and, after rubbing shoulders with the youngsters, his interest
was sparked. His attitude grew more positive over the...
