In an experiment with such a\npendulum in 1851, Foucault was able to prove for the first time in a simple way\nthat the earth rotates. Before that, one always had to rely on long observations\nof the night sky and calculations. With this experiment, it has been possible to\nmake the earth's rotation accessible in a relatively simple way, even to people\nwith little or no knowledge of physics.\n\n![Website image](images/website.png)\n\n## How is this experiment performed?\n\nThe pendulum is set up at a fixed point and brought into an initial position,\nwhere the release of a band with the help of fire sets the pendulum in swinging\nmotion. This is to prevent unwanted movement and additional swing and spin.\n\n## What can be observed?\n\nAt the poles of our earth, after about 23.93 hours, it would look as if the\npendulum had turned 360°, but in fact it is the earth that turns under the\npendulum and this turn is not transmitted to the swinging object. At the equator\nthis is different, because there the path of the pendulum does not seem to\nchange. This is due to the fact that a day on earth, with its almost 24 hours,\ndivided by the sine of the latitude at the equator is 0.\n$$0=\\frac{23.99}{sin(0)}$$\n\n## Availability\n\n- [https://btschwertfeger.github.io/Foucaults-Pendulum-Website/](https://btschwertfeger.github.io/Foucaults-Pendulum-Website/)\n\u003c!-- - [https://www.awi.de/ ....](https://www.awi.de/fileadmin/user_upload/AWI/Forschung/Klimawissenschaft/Dynamik_des_Palaeoklimas/OrbitalTheoryOfIceAges/) --\u003e\n\n## References\n\n- Gerrit Lohmann (2021), provided a R implementation of the equations of the\n  pendulum\n\n- \u003ca target=\"_blank\"\n  href=\"https://www.kip.uni-heidelberg.de/image/f/oeffwiss/pendel/Foucault.pdf\"\u003e\n  The Foucault Pendulum \u003c/a\u003e - a Simplified Trajectory Analysis for a Pendulum\n  on a Turntable and an Outlook to a Pendulum on Earth, A.
