Gdańsk University of Technology crowned with a gilded image of the Allegory of Science. The main building encloses inner courtyards covered by glass domes designed by W. Czabański and Z. Wilk and installed in 2004. In 2012 the South Courtyard was officially renamed in honour of Johannes Hevelius. The Foucault pendulum is designed to show the rotation of the Earth on its axis. It is named after the French physicist who first performed a similar experiment at the Paris Pantheon in 1851. The machine that made its appearance in 2005 in the South Courtyard of Gdansk University of Technology is a 64 kg metal
Foucault pendulum vector diagrams the bob is still rotating (turning) with the Earth with the same angular velocity equal to that of the Earth's angular velocity. This is the same angular velocity when at rest. Since the central axis of the pendulum is perpendicular with the axis of rotation of the Earth this is not the same as the North Pole where the central axis is aligned with the axis of the Earth. The bob is not revolving about the axis of the pendulum when held in place. Once the bob is displaced from the central axis of the pendulum and then released there
