Michel Foucault of left-wing groups involved in campaigns against racism and human rights abuses and for penal reform. Foucault later published "Discipline and Punish" (1975) and "The History of Sexuality" (1976), in which he developed archaeological and genealogical methods which emphasized the role that power plays in society. Foucault died in Paris of neurological problems compounded by HIV/AIDS; he became the first public figure in France to die from the disease. His partner Daniel Defert founded the AIDES charity in his memory. Paul-Michel Foucault was born on 15 October 1926 in the city of Poitiers, west-central France, as the second of three
Foucault pendulum vector diagrams of the North Pole, equal to zero since zero distance is traveled in relation to the spinning Earth. Even though the surface velocities are different the angular velocities underneath the pendulum swing are all the same for this orientation. For the 45° North pendulum with latitudinal swing (Figure 3B) the support point of the pendulum swing is moving along with the direction of rotation and the surface velocity vectors on either side of the swing are not balanced. The rotation of the Earth is observable in relation to the pendulum swing because a change in relationship to the surface occurs.
