Superstring theorySuperstring theory is an attempt to explain all of the particles and fundamental forces of nature in one theory by modeling them as vibrations of tiny supersymmetric strings. 'Superstring theory' is a shorthand for supersymmetric string theory because unlike bosonic string theory, it is the version of string theory that accounts for both fermions and bosons and incorporates supersymmetry to model gravity. Since the second superstring revolution, the five superstring theories (Type I, Type IIA, Type IIB, HO and HE) are regarded as different limits of a single theory tentatively called M-theory.
M-theoryM-theory is a theory in physics that unifies all consistent versions of superstring theory. Edward Witten first conjectured the existence of such a theory at a string theory conference at the University of Southern California in 1995 (M-Theory - Edward Witten (1995)). Witten's announcement initiated a flurry of research activity known as the second superstring revolution. Prior to Witten's announcement, string theorists had identified five versions of superstring theory.
String theoryIn physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass, charge, and other properties determined by the vibrational state of the string.
Critical theoryA critical theory is any approach to social philosophy that focuses on society and culture to attempt to reveal, critique, and challenge power structures. With roots in sociology and literary criticism, it argues that social problems stem more from social structures and cultural assumptions than from individuals. It argues that ideology is the principal obstacle to human liberation. Critical theory finds applications in various fields of study, including psychoanalysis, sociology, history, communication theory, philosophy and feminist theory.
Holomorphic vector bundleIn mathematics, a holomorphic vector bundle is a complex vector bundle over a complex manifold X such that the total space E is a complex manifold and the projection map π : E → X is holomorphic. Fundamental examples are the holomorphic tangent bundle of a complex manifold, and its dual, the holomorphic cotangent bundle. A holomorphic line bundle is a rank one holomorphic vector bundle. By Serre's GAGA, the category of holomorphic vector bundles on a smooth complex projective variety X (viewed as a complex manifold) is equivalent to the category of algebraic vector bundles (i.
Marco EvaristtiMarco Evaristti (born 1963) is a Chilean artist who has lived in Denmark since the 1980s. While a trained and practicing architect, he is best known for hosting a dinner party where the main course was agnolotti pasta that was topped with a meatball made with his own fat, removed earlier in the year in a liposuction operation. Though raised a Catholic, in his teenage years Evaristti found out he was born to a Jewish mother, which some account for the philosophical and religious themes in his work.
Federico CastellónFederico Castellón ( – ) was a Spanish American painter, sculptor, printmaker, and illustrator of children's books. Castellón was born on Alhabia, Almeria, Spain, studied in Madrid and Paris and settled in Brooklyn, New York. Federico Cristencia de Castellón y Martínez, better known as Federico Castellón, was a surrealist printmaker, illustrator, painter, and sculptor. He was born in Almeria, Spain in 1914. With his family, he immigrated in 1921 to the United States. They resided in Brooklyn, New York.

José María CanoJosé Cano Andrés (born 21 February 1959) is a Spanish visual artist, musician, composer, and record producer. From 1982 to 1998, he was a member and principal composer of the Spanish pop-rock band Mecano. Since 1998, he works primarily in the visual arts. José Maria Cano was born in Madrid, and gave his first concerts as a university student there. There he met Ana Torroja, who would become the lead singer in their pop band Mecano. Their first album, also called Mecano (1981) and produced with the financial backing of his father, included the hit "Hoy No Me Puedo Levantar".
André MeyerAndré Benoît Mathieu Meyer (September 3, 1898 – September 9, 1979) was a French-American investment banker. Meyer was born to a low-income Jewish family in Paris. As a boy, he began following the workings of the stock market and out of necessity left school at age sixteen to work as a messenger at the Paris Bourse. Ambitious, he used his time to study the intricacies of stock trading and because of personnel shortages created by so many young French men serving in the military in World War I, he was able to get a job with Baur & Fils, a small Paris bank.
Mirabelle (London restaurant)Mirabelle was a restaurant in the Mayfair area of London. It opened in 1936, and became popular during the 1950s and 1960s, with some celebrities being regulars. Chef Marco Pierre White owned it from 1998 to 2007, and it earned a Michelin star in 2000 under head chef Charlie Rushton, and kept it until its closure for refurbishment in 2008. It remained closed until the site was demolished in 2016/17. The restaurant was first opened in 1936. The interior has a single main dining room, and two private dining rooms entitled the Pine Room and the Chinese Room.
Line (geometry)In geometry, a line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects, though they may exist embedded in two, three, or higher dimensional spaces. The word line may also refer to a line segment in everyday life that has two points to denote its ends (endpoints). A line can be referred to by two points that lie on it (e.g. ) or by a single letter (e.g. ).
