In quantum mechanics, Bell's Theorem states that a Bell inequality must be obeyed under any local hidden variable theory but can in certain circumstance be violated under quantum mechanics (QM). The term "Bell inequality" can mean any one of a number of inequalities — in practice, in real experiments, the CHSH or CH74 inequality, not the original one derived by John Bell. It places restrictions on the statistical results of experiments on pairs of particles that have taken part in an interaction and then separated. A Bell test experiment i ...

The Asch conformity experiments were a series of studies that starkly demonstrated the power of conformity in groups. Experimenters led by Solomon Asch asked students to participate in a "vision test." In reality, all but one of the participants were confederates of the experimenter, and the study was really about how the remaining student would react to the confederates' behavior. The participants — the real subject and the confederates — were all seated in a classroom where they were told to announce their judgment ...

The Collatz conjecture is an unresolved conjecture in mathematics. It is named after Lothar Collatz, who first proposed it in 1937. The conjecture is also known as the 3n + 1 conjecture, the Ulam conjecture (after Stanislaw Ulam), the Syracuse problem, as the hailstone sequence or hailstone numbers, or as Wondrous numbers as per Gödel, Escher, Bach. It asks whether a certain kind of number sequence always ...

In the statistical theory of the design of experiments, blocking is the arranging of experimental units in groups (blocks) which are similar to one another. For example, an experiment is designed to test a new drug on patients. There are two levels of the treatment, drug, and placebo, administered to male and female patients in a double blind trial. The sex of the patient is a blocking factor accounting for treatment variablility between males and females. This reduces sources of variab ...

Art Collective are groups of artists who collaborate or come together for combined productions or activities. More traditional art collectives tend to be smallish groups of two to eight artists who produce gallery shows and maintain a collective space, while some newer, more experimental kinds of groups include intentional networks, anonymous, connector, hidden or nest ...

Cybotron was an electro group formed in 1980 by Juan Atkins and Richard "3070" Davis in Detroit, Michigan. Singles such as the groundbreaking single "Clear" and their debut single "Alleys of Your Mind," as well as "Cosmic Cars" and "R-9" married a funk-feel to explorations of Detroit's experimental electronic music landscape. The group was signed to the Berkeley-based Fantasy label and released their debut album "Enter" in 1983. Cybotron were inspired by European synthesizer pioneers Kraftwerk and literary influences such as Al ...

Yeasts constitute a group of single-celled (unicellular) fungi, a few species of which are commonly used to leaven bread , ferment alcoholic beverages, and even drive experimental fuel cells. Most yeasts belong to the division Ascomycota. A few yeasts, such as Candida albicans, can cause infection in humans. More than one thousand species of yeasts have been described. The most commonly used yeast is Saccharomyces cerevisiae, which was domesticated for wine, bread, ...

An artificial or constructed language (known colloquially as a conlang among aficionados), is a language whose phonology, grammar and vocabulary are specifically devised by an individual or small group, rather than having naturally evolved as part of a culture as with natural languages. Some are designed for use in human communication (usually to function as international auxiliary languages), but others are created for use in fiction, linguistic experimentation, secrecy (codes), or for the experience of doing so (artistic languages, language games). These ...

An artificial or constructed script (also conscript or neography) is a new writing system specifically created by an individual or group, rather than having evolved as part of a culture like a natural script. They are often designed for use with conlangs, although several of them are used in linguistic experimentation or for other more practical ends. Some, such as the Shavian alphabet, Alphabet 26, and the Deseret alphabet, were devised as English spelling reforms. Others, including Alexander Melville Bell's Visi ...

Unconventional superconductors are materials that display superconductivity but that do not conform to BCS theory and Nikolay Bogolyubov theory or its extensions. The first unconventional triplet superconductor, organic material (TMTSF)2PF6, was discovered by Denis Jerome and Claus Bechgaard in 1979. Recent experimental works by Paul Chaikin's and Michael Naughton's groups as well as theoretical analysis of their data by Andrei Lebed have firmly confirmed unconventional triplet nature of superc ...

Creative writing is a term used to distinguish certain imaginative or different types of writing from generic writing. The lack of specificity of the term is partly intentional, designed to make the process of writing accessible to everyone (of all ages) and to ensure that non-traditional, or traditionally low-status writing (for example, writing by marginalized social groups, experimental writing, genre fiction) is not excluded from academic consideration or dismissed as trivial or insignificant. This distinction is helpful in separating the writing from more technical ...

Although most historical reenactment groups follow a very loose interpretation of history (sometimes mixing equipment closely related periods or often just the use of inauthentic materials: eg. cotton clothes in a medieval setting) some groups go a step further and mix historical elements with elements of the Fantasy genre or incorporate modern technology or culture into a historical setting (often simply reducing the level of authenticity for increased safety or reduced costs, ...

Many castles, museums, and other historical tourist attractions employ actors or professional reenactors as part of the experience. These usually address the recreation of a specific town, village, or activity within a certain time frame. Commercial reenactment shows are usually choreographed and follow a script.

One of the main motivations for SUSY comes from the quadratic divergence of the mass squared of scalar bosons. Put more simply, it means most quantum field theories predict that the mass of a scalar boson, when run down the renormalization group, is of the order of the cutoff scale (i.e. the scale at which new physics appears). Since the Higgs field in the Standard Model is a scalar field, this poses a problem if we assume that the cutoff scale is really high, like in most nonsupersymmetric GUT models where there is a desert of many orders o ...

Traditional symmetries in physics are generated by objects that transform under the various tensor representations of the Poincaré group. Supersymmetries, on the other hand, are generated by objects that transform under the spinor representations. According to the spin-statistics theorem bosonic fields commute while fermionic fields anticommute. In order to combine the two kinds of fields into a single algebra requires the introduction of a Z2-grading under which the bosons are the even elements and the fermions are the ...
