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 each figure represents the range of swing of the pendulum as viewed from above and normalized to a standard orientation. The smaller arrows depict the magnitude of the relative velocity vector for the point on the Earth's surface in-line with the pendulum bob projected to the center of the Earth (the magnitude is shown since the scematic is two-dimensional, not three-dimensional). The pendulum bob is always affected by the force of gravity directed towards the center of the Earth. The force associated with the connection of the pendulum to a support structure directs the pendulum bob along the swing
