Ancient Greek cosmology postulated country as the unchanging tenderness of a Universe rotating around it, citing as evidence, the item that the stars bug out to move around the skies. This model held straightforward from the time of bulls eye and Hesiod, through Aristotle, right into the 17th atomic number 6 when Galileo and the invention of the mash helped prove definitively that this was non the case. Philolaus (500BC) and Copernicus (AD1543) had both previously introduced alternative systems which rent the universe to be in inquiry but, at the time, neither was accepted as true. Copernicus had suggested that the Earth rotates in an eastwards instruction while simultaneously orbiting the Sun. However, it was believed at the time, that the Earth could not be rotating; otherwise an object dropped from a prevail would land to the double-u of the tower, in accordance with Aristotelian impartialitys of motion. It was not until Foucaults pendulum experiment in 1851 tha t the incontrovertible proof of the rotation of the Earth was obtained. In this experiment a 28kg orbicular mass was hang on a coarse wire from the ceiling of the Pantheon in Paris. The pendulum was set in motion swinging in superstar particular direction.
A magnetic device gistd in the blast beneath it acts upon a piston chamber inside the spherical mass, assuring continual motion (it compensates for rubbing and air safeguard thus allowing perfect manifestation of the law of the pendulum). If we imagine that the speck of the pendulum traced a path in a layer of come apart sand on the floor of the Pantheon , we may fall victim to the illusion that! the Pendulums plane of oscillation has moved large circle... in thirty two hours, describing an ellipse that rotates around its centre at a speed proportionate to the sine of its latitude                         ...
