Stephen Chu's Pendulum High School Experiment

For the better part of my last semester at Garden City High, I constructed a physical pendulum and used it to make a 'precision' measurement of gravity. The years of experience building things taught me skills that were directly applicable to the construction of the pendulum. Twenty-five years later, I was to develop a refined version of this measurement using laser-cooled atoms in an atomic fountain interferometer.

 Carl Sagan Punished for Popularizing Science

Yet instead, Sagan was punished by the scientific community for his public endeavors. The persecution began as early as the 1960s, when Harvard University denied him tenure. Nobel laureate Harold Urey, a chemist who had previously served as one of Sagan's mentors, helped quash his chances with a nasty letter objecting to Sagan's budding media and outreach efforts.
