Inauguration of the “Bro. Martin Pendulum” Landmark

The AU physic and scientific monumental symbol of “Pendulum” (reminiscent of Foucault’s Pendulum) installed on the 1st floor of the Vincent Mary School of Engineering, Suvarnabhumi Campus, was officially inaugurated on November 11, 2020.

Unveiling the hanging round ball-like “Pendulum”, Rev. Bro. Dr. Bancha Saenghiran, President-Rector Magnificus, stressed about its scientific and astronomical significance, human’s curious learning and observation; testifying of the Antithesis of the Geocentric Model or theory of a French Physicist, Jean-Bernard-Leon Foucault, who mounted a large pendulum using an iron ball under the central dome of the Pantheon in Paris to prove that the earth is not the center of the universe and that the Earth spins or revolves on its axis eastward or counterclockwise.

It is worth noting that the time it takes for a complete rotation depends on the latitude of the experiment. For instance, at the latitude of Paris, the pendulum’s path would complete a full clockwise rotation every 30 hours; on the Southern Hemisphere it would rotate counterclockwise, and on the Equator it wouldn’t revolve at all.

Recently in 1984 and 2001, when modern-day scientists replicated Foucault’s pendulum experiment at the South Pole, they discovered the period of rotation was 24 hours.
