Noether's theoremNoether's theorem or Noether's first theorem states that every differentiable symmetry of the action of a physical system with conservative forces has a corresponding conservation law. The theorem was proven by mathematician Emmy Noether in 1915 and published in 1918. The action of a physical system is the integral over time of a Lagrangian function, from which the system's behavior can be determined by the principle of least action. This theorem only applies to continuous and smooth symmetries over physical space.
Palacio de las DueñasPalacio de las Dueñas (occasionally, Casa Palacio de las Dueñas) is a palace in Seville, Spain, currently belonging to the House of Alba. It was built in the late 15th century in the Renaissance style with Gothic and Moorish influences. The palace is one of the major historic homes of great architectural and artistic heritage in the city. The poet Antonio Machado was born here, as were Carlos Falcó, 5th Marquess of Griñón and the Marquess of Castel-Moncayo.
