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 be determined. The inverse ratio will determine the time observed for one full rotation of the pendulum swing in comparison to the duration at the pole of one day. From the diagrams two points of the pendulum swing can be chosen to project straight down to two points on opposite sides of the Earth (180° apart). This makes it easy to obtain the velocity vector difference and then the time observed for a full rotation from the inverse ratio. The examples show that the Earth turns underneath the plane of the pendulum swing and how this change in relationship can
