Earth's rotation Foucault in 1851, which consisted of a lead-filled brass sphere suspended from the top of the Panthéon in Paris. Because of the Earth's rotation under the swinging pendulum, the pendulum's plane of oscillation appears to rotate at a rate depending on latitude. At the latitude of Paris the predicted and observed shift was about clockwise per hour. Foucault pendulums now swing in museums around the world. Earth's rotation period relative to the Sun (solar noon to solar noon) is its "true solar day" or "apparent solar day". It depends on the Earth's orbital motion and is thus affected by changes
Orgone accumulator. The song "Cloudbusting" by British singer Kate Bush describes Reich's arrest and incarceration through the eyes of his son, Peter. The 1985 video, in which Donald Sutherland plays Wilhelm Reich during his research and subsequent arrest, features a Foucault pendulum as an alternative method of demonstrating the rotational motion of the earth to prove the heretical view that the Earth was not the centre of the Universe. The Foucault pendulum in this video simultaneously connects and contrasts the disgraced Wilhelm Reich to both of the respected Foucaults, the scientist, Jean Bernard Léon Foucault and the philosopher, Michel Foucault, who
