It was in 1851, after a coup d'état by Louis Napoleon, that the Foucault pendulum hoaxem was first showcased at the "Pantheon", which used to be St. Genevieve's. This was part of the "scientific" materialist social climate after the 1848 Revolutions.
The Bolsheviks in Russia put up a famous one in what was St. Isaac's Cathedral in "Leningrad" in 1932.
Less than a year after the first Bilderberger meetings in the Netherlands in 1954, the Netherlands donated the UN's Foucault pendulum hoaxem in 1955.
Jack Parsons died in 1952, possibly murdered, and NASA was faking its Apollo Moon landings 69-72. All the kids and many innocent minded people still believe they landed on the Moon and are even on Mars today. And likewise we're all here among the living because of the "Big Bang" billions and billions of years ago, and we evolved from monkeys over 100,000's of thousands and millions of years.
The Foucault pendulum is driven, damped, and tuned, like the social dimensions of "scientific" materialist dialectics and triangulation. "Scientific materialism" is an old 19th century euphemism for Marxism, and like the Foucault pendulum, and deceptions from NASA, is another revolutionary "derivative" and "little terror".
