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 is still the same force acting on the bob that causes it to rotate (turn) with the Earth. The point of significance is that the same forces imparting an angular velocity to the pre-released bob are still acting on the swinging bob. At the Equator, the relative motion of the Earth is not observable because there is no change in the force imparting an angular velocity to the bob. This is because the central axis of the pendulum is perpendicular with the axis of rotation of the Earth. At intermediate latitudes: The rotation of the Earth is observable in relation
