For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself.
The film discusses Galileo's contributions to the laws of motion and gravitation, emphasizing that all objects fall at the same rate regardless of their weight. It recounts the legend of Galileo ...
