NOVA investigates the 800-year battle between the leaning Tower of Pisa and the engineers struggling to keep it upright.
The program:
examines how the tip of the 14,000-ton (12,700 metric tons) medieval tower has come to lean 16 feet (5 meters) off center.
reveals how engineering experts offered varying solutions to prevent the tower's collapse.
describes how the tower reacts to sunlight, rain, and vibrations.
reviews the politics surrounding repairing the tower's lean.
portrays working models that predict what may happen if the tower is subjected to human interventions like propping and soil extraction.
shows how many generations have tried and failed to compensate for the tower's lean.
