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 Spin of a relativistic particle moving in a circular orbit precesses similar to the swing plane of Foucault pendulum. The relativistic velocity space in Minkowski spacetime can be treated as a sphere "S" in 4-dimensional Euclidean space with imaginary radius and imaginary timelike coordinate. Parallel transport of polarization vectors along such sphere gives rise to Thomas precession, which is analogous to the rotation of the swing plane of Foucault pendulum due to parallel transport along a sphere "S" in 3-dimensional Euclidean space. In physics, the evolution of such systems is determined by geometric phases. Mathematically they are understood through parallel
