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 to describe the rotation angle of the swing plane of Foucault's pendulum. From the perspective of an Earth-bound coordinate system with its "x"-axis pointing east and its "y"-axis pointing north, the precession of the pendulum is described by the Coriolis force. Consider a planar pendulum with natural frequency "ω" in the small angle approximation. There are two forces acting on the pendulum bob: the restoring force provided by gravity and the wire, and the Coriolis force. The Coriolis force at latitude "φ" is horizontal in the small angle approximation and is given by where Ω is the rotational frequency of
