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.
Notes:
He used the pendulum to make a precise measurement of gravity, and the process would eventually inform his Nobel Prize winning work.
