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 On one side of the pendulum swing the surface velocity vectors are angled upwards and to the side but on the other side the vectors are angled downwards and to the opposite side. Since these vectors are not all in the same plane as the pendulum swing and are not balanced in the same direction there is a change in relationship between the surface and the plane of the pendulum swing. The surface velocity vectors underneath the swing of the pendulum can be separated into three components ("x", "y", and "z") for the 3-dimensional system in order to evaluate the
