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
Pendulum measured in parts of France, Italy, Croatia, Serbia, Romania, Russia, Kazakhstan, China, Mongolia, the United States and Canada. In addition, it could be recreated at any location at which the gravitational acceleration had been accurately measured. By the mid 19th century, increasingly accurate pendulum measurements by Edward Sabine and Thomas Young revealed that gravity, and thus the length of any pendulum standard, varied measurably with local geologic features such as mountains and dense subsurface rocks. So a pendulum length standard had to be defined at a single point on Earth and could only be measured there. This took much of
