At this balance point, the droplet would hover motionless. Data Analysis and Refining Precision Millikan's meticulous methodology extended beyond simple observation; it involved rigorous statistical analysis.
Millikan Oil Drop Experiment Procedure Steps: Balancing Forces and Measuring Charge
It bridged the gap between theoretical predictions and empirical measurement. Was electric charge continuous, like a smooth flowing liquid, or was it discrete, existing in specific, indivisible units? This profound inquiry found its answer in a seemingly simple apparatus involving oil droplets and meticulously controlled electric fields.
This level of precision was unprecedented for its time and demonstrated the power of careful experimental design. Thomson had already discovered the electron, a subatomic particle carrying a negative charge.
