Energy economicsEnergy economics is a broad scientific subject area which includes topics related to supply and use of energy in societies. Considering the cost of energy services and associated value gives economic meaning to the efficiency at which energy can be produced. Energy services can be defined as functions that generate and provide energy to the “desired end services or states”. The efficiency of energy services is dependent on the engineered technology used to produce and supply energy. The goal is to minimise energy input required (e.
Wave function collapseIn quantum mechanics, wave function collapse occurs when a wave function—initially in a superposition of several eigenstates—reduces to a single eigenstate due to interaction with the external world. This interaction is called an observation, and is the essence of a measurement in quantum mechanics, which connects the wave function with classical observables such as position and momentum. Collapse is one of the two processes by which quantum systems evolve in time; the other is the continuous evolution governed by the Schrödinger equation.
WKB approximationIn mathematical physics, the WKB approximation or WKB method is a method for finding approximate solutions to linear differential equations with spatially varying coefficients. It is typically used for a semiclassical calculation in quantum mechanics in which the wavefunction is recast as an exponential function, semiclassically expanded, and then either the amplitude or the phase is taken to be changing slowly. The name is an initialism for Wentzel–Kramers–Brillouin. It is also known as the LG or Liouville–Green method.
AndreaAndrea is a given name which is common worldwide for both males and females, cognate to Andreas, Andrej and Andrew. The name derives from the Greek word ἀνήρ (anēr), genitive ἀνδρός (andrós), that refers to man as opposed to woman (whereas man in the sense of human being is ἄνθρωπος, ánthropos). The original male Greek name, Andréas, represents the hypocoristic, with endearment functions, of male Greek names composed with the andr- prefix, like Androgeos (man of the earth), Androcles (man of glory), Andronikos (man of victory).
Particle in a boxIn quantum mechanics, the particle in a box model (also known as the infinite potential well or the infinite square well) describes a particle free to move in a small space surrounded by impenetrable barriers. The model is mainly used as a hypothetical example to illustrate the differences between classical and quantum systems. In classical systems, for example, a particle trapped inside a large box can move at any speed within the box and it is no more likely to be found at one position than another.
EdoEdo (), also romanized as Jedo, Yedo or Yeddo, is the former name of Tokyo. Edo, formerly a jōkamachi (castle town) centered on Edo Castle located in Musashi Province, became the de facto capital of Japan from 1603 as the seat of the Tokugawa shogunate. Edo grew to become one of the largest cities in the world under the Tokugawa. After the Meiji Restoration in 1868 the Meiji government renamed Edo as Tokyo (, "Eastern Capital") and relocated the Emperor from the historic capital of Kyoto to the city.
San Andreas (film)San Andreas is a 2015 American disaster film directed by Brad Peyton and written by Carlton Cuse, with Andre Fabrizio and Jeremy Passmore receiving story credit. The film stars Dwayne Johnson, in the lead role, Carla Gugino, Alexandra Daddario, Ioan Gruffudd, Archie Panjabi and Paul Giamatti. Its plot centers on a massive earthquake caused by the San Andreas Fault, devastating the West Coast of the United States. Principal photography of the film started on April 22, 2014, in Queensland, Australia, and wrapped up on July 28 in San Francisco.
St Andrew's Church, Andreas, Isle of ManSt Andrew's Church, Andreas, is a Church of England parish church in Andreas, Isle of Man. The church is administered by the Diocese of Sodor and Man. It is generally supposed that Christianity was introduced to the Isle of Man by St Patrick about the middle part of the 5th Century and that St German was appointed as the first Bishop of Man. Under the influence of St Patrick and what is referred to as his "Romish missionaries," the Isle of Man saw the erection of a series of small chapels throughout the Island.
Small Island (novel)Small Island is a 2004 prize-winning novel by British author Andrea Levy, her fourth novel. The novel is based on four main characters—Hortense, Queenie, Gilbert and Bernard—and the story is told from each of their points of view. Mainly set in 1948, the plot focuses on the diaspora of Jamaican immigrants, who, escaping economic hardship on their own "small island", move to England, the Mother Country, for which the men have fought during World War II.
Derived categoryIn mathematics, the derived category D(A) of an A is a construction of homological algebra introduced to refine and in a certain sense to simplify the theory of derived functors defined on A. The construction proceeds on the basis that the of D(A) should be chain complexes in A, with two such chain complexes considered isomorphic when there is a chain map that induces an isomorphism on the level of homology of the chain complexes. Derived functors can then be defined for chain complexes, refining the concept of hypercohomology.
