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. On October 5, 2011 Cayetana Fitz-James Stuart, 18th Duchess of Alba married her third husband here.
EquationIn mathematics, an equation is a mathematical formula that expresses the equality of two expressions, by connecting them with the equals sign . The word equation and its cognates in other languages may have subtly different meanings; for example, in French an équation is defined as containing one or more variables, while in English, any well-formed formula consisting of two expressions related with an equals sign is an equation. Solving an equation containing variables consists of determining which values of the variables make the equality true.
Conservation lawIn physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of mass-energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge. There are also many approximate conservation laws, which apply to such quantities as mass, parity, lepton number, baryon number, strangeness, hypercharge, etc.
Conservation of energyIn physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all forms of energy that were released in the explosion, such as the kinetic energy and potential energy of the pieces, as well as heat and sound, one will get the exact decrease of chemical energy in the combustion of the dynamite.

Anthony SteffenAnthony Steffen, born Antonio Luiz de Teffé von Hoonholtz (July 21, 1930 – June 4, 2004), was an Italian-Brazilian character actor, screenwriter and film producer. Steffen achieved fame as a leading man in Spaghetti Western features. He was also known as Antonio Luigi de Teffe. Born Antonio Luiz de Teffé von Hoonholtz at the Brazilian embassy in Rome, in the Pamphilj Palace, his family had noble blood of a long lineage of Count (von Hoonholtz) originally from Prussia; his great grandfather was the Great Baron of Teffé.
Mathematical modelA mathematical model is an abstract description of a concrete system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in applied mathematics and in the natural sciences (such as physics, biology, earth science, chemistry) and engineering disciplines (such as computer science, electrical engineering), as well as in non-physical systems such as the social sciences (such as economics, psychology, sociology, political science).
Mathematical physicsMathematical physics refers to the development of mathematical methods for application to problems in physics. The Journal of Mathematical Physics defines the field as "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories". An alternative definition would also include those mathematics that are inspired by physics (also known as physical mathematics).
Equation solvingIn mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns. A solution is an assignment of values to the unknown variables that makes the equality in the equation true. In other words, a solution is a value or a collection of values (one for each unknown) such that, when substituted for the unknowns, the equation becomes an equality.
German ArgentinesGerman Argentines (Deutschargentinier, germano-argentinos) are Argentines of German ancestry as well as German citizens living in Argentina. They are descendants of Germans who immigrated to Argentina from Germany and elsewhere in Europe. Some German Argentines originally settled in Brazil, then later immigrated to Argentina. Although Germany as a political entity was founded in 1871, the German language and culture have traditionally been more important than the country of origin, as the basis of the ethnic and national consciousness of Germans.
Hamiltonian mechanicsHamiltonian mechanics emerged in 1833 as a reformulation of Lagrangian mechanics. Introduced by Sir William Rowan Hamilton, Hamiltonian mechanics replaces (generalized) velocities used in Lagrangian mechanics with (generalized) momenta. Both theories provide interpretations of classical mechanics and describe the same physical phenomena. Hamiltonian mechanics has a close relationship with geometry (notably, symplectic geometry and Poisson structures) and serves as a link between classical and quantum mechanics.
