Revisiting Riccioli’s free-fall calculations
Abstract
In 1651 Giovanni Riccioli reported the earliest accurate measurements the acceleration due to gravity, g, from pendulum-timed free fall experiments. The use of Huygens' pendulum formula (published 1673) allows one to deduce the pendulum length from this data, free from assumptions about the conversion to modern units, and independent of the actual value of g. When this length is compared to the reported pendulum length, a 15% systematic error is...
