  The purpose of this paper is to give an intuitive explanation of the Foucault
pendulum precession (Fpp) by exploiting the easily proved result that
infinitesimal spatial rotations about different axes in three dimensions are
additive. This allows to explain in a simpler way the Foucault precession by
combining physical laws, intuition and a few elementary notions of astronomy.
The paper is by no means intended to replace the material given in standard
texts of classical mechanics; it is only an interdisciplinary description of
the Foucault precession tailored for non specialists.
