Summary
Until the mid-19th century, there was no definitive proof that the Earth turned on its axis. The notion that the Earth stood motionless at the center of the unchanging universe and that the Sun and planets orbited around it in perfectly circular paths was deeply embedded in scientific, cultural, and biblical history. Plato and Aristotle embraced and taught this geocentric theory. In the third century AD, Claudius Ptolemy gathered everything then known about astronomy and published a 13-volume book, The Almagest, that perpetuated the Earth-centered universe. Unfortunately, it remained the authority on astronomy for over 1000 years. It took two thousand years for the heliocentric or sun-centered model to replace the geocentric model. Nicholas Copernicus put the Sun at the center of the solar system. Johan Kepler and Isaac Newton showed that orbital paths were ellipses, not circles. Astronomers found that rather than occupying a special place at the center of the Universe, the Earth was but a tiny part of our Solar System, itself but a tiny part of a galaxy, itself but a tiny part of the Universe. Tycho Brahe observed a supernova that showed the Universe did change. One concept of the old system, that the Earth did not turn on its axis, was particularly difficult to dislodge. The reason for this is that evidence offered to show that the Earth turned could often also be used to prove the opposite. Léon Foucault stunned the scientific world with a simple experiment that provided incontrovertible evidence that the Earth turned on its axis. The date was February 3, 1851; the demonstration was a long pendulum hung from the ceiling of the Meridian Hall in the Paris Observatory. Join us and you too will see the Earth turn when we re-enact Léon Foucault’s epic experiment with a miniature version of his pendulum
