Timelapsing the Foucault pendulum. This work was inspired by the work of Léon Foucault who in 1851, proved that the earth was rotating by creating a very large pendulum that moved in a straight line relative to itself, but would appear to process around in a circle over the course of time. #foucalt #foucaultpendulum #granite #art #stone #concept #spiral #ellipse #sanddrawing @llanoearthartfest | Stone Point Studio

While the Earth 🌎 rotates underneath, the orientation of the #pendulum changes. First used in 1851, Foucault's pendulum was the first simple, direct way to observe Earth's rotation. 🎵: Fin Draper | Griffin Museum of Science and Industry
