Foucault's Pendulum lecture. This lecture,'On the Rotation of the Earth',was delivered at the Royal Institution,London,in 1851 by the British mathematician and Savilian Professor of Geometry Baden Powell (1796-1860). This lecture was one of many prompted by the initial demonstration of Foucault's Pendulum,carried out in Paris,France,in February 1851,by French physicist Leon Foucault (1819-1868). The experiment involves a heavy pendulum swinging on a long arm. The vertical plane in which the pendulum swings rotates with time due to the Earth's daily rotation. Only part of the full circular rotation is shown here | |
