Foucault pendulum sharing the rotation of the earth about its own axis, the suspension point of the pendulum traces out a circular path during one sidereal day. At the latitude of Paris, 48 degrees 51 minutes north, a full precession cycle takes just under 32 hours, so after one sidereal day, when the Earth is back in the same orientation as one sidereal day before, the oscillation plane has turned by just over 270 degrees. If the plane of swing was north-south at the outset, it is east-west one sidereal day later. This also implies that there has been exchange of momentum;
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
