The Foucault Pendulum

“And yet it moves!” How can you prove that the Earth rotates on its axis without going into space? Just come to the entrance hall of the Faculty of Science where you will find a giant Foucault pendulum – the famous experimental device named after its French inventor, which demonstrates our planet’s rotation.

The Foucault pendulum at the natural sciences faculty passes through six floors and measures 25.5 metres in length, making it the longest Foucault pendulum in the Czech Republic. The pendulum is kept in motion by an electromagnet with the help of four lasers that track its position; it was placed in the building by one of the optics students as part of his thesis.
