While most clocks are accurate enough for our practical day to day purposes, clocks often disagree when measuring time intervals. There is a wide range of frequency stability among clocks. Additionally, gravitational time dilation can cause clocks on the ground to disagree about the time with clocks in the air‒‒enough that gps satellites must continually adjust their clocks to match with those on the ground in order to work properly. In this project, several different oscillators were built and their frequencies are analyzed. Attempts to measure gravitational time dilation with a high altitude balloon are considered, with the conclusion that this can be accomplished with atomic clocks, but not the quartz crystal oscillator.
