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
Paraconical pendulum about its vertical axis as well as swinging in two perpendicular directions. Therefore a paraconical pendulum has three degrees of freedom. When the rotation of the Earth is taken into account, the formal equations in classical mechanics of the behavior of this dynamical system are rather complex. The rolling friction of the ball upon the flat is extremely low, so that a paraconical pendulum has a high Q factor, principally determined by air resistance. Typically a paraconical pendulum is built as a solid body with a stiff rod, rather than with a flexible wire or cord, and its length is
