The Foucault Pendulum as well as the Christmas tree represent the transformation of originally scientific phenomena in to spiritual symbolism.
Where the Christmas tree and its symbolic power of a green tree projects hope throughout the cold time of year, the pendulum swings as evidence of the earth’s rotation and defies the religious zealots with their geocentric beliefs.
In its original meaning, Christmas is a celebration of solstice and with that of the earth circling the deity “sun”. In this sense, the pendulum and the tree find themselves in an immediate relationship with the Enlightenment and the fight against spirituality as a power tool. Both are references to a world view of humankind that revolves around itself.
