The Golden Verses of Pythagoras
The Golden Verses of Pythagoras (Greek: Χρύσεα Ἔπη, Chrysea Epê; Latin: Aurea Carmina) are a collection of moral exhortations. They comprise 71 lines written in dactylic hexameter verse and are traditionally attributed to Pythagoras. The exact origins of the Golden Verses are unknown and there are varying opinions regarding their dating. It appears that the verses may have been known as early as the third century BCE but their existence as we know them cannot be confirmed prior to the fifth century CE. The Golden Verses enjoyed great popularity and were widely distributed in late antiquity, being often quoted. Their renown persisted during the medieval ages and into the Renaissance. In 1494 the Neoplatonic Greek scholar Constantine Lascaris published in a famous printed edition of his Grammatica, deliberately, the Golden Verses translated into Latin, thereby bringing them to a widespread audience. The Neoplatonists used the Golden Verses as part of their preparatory program of moral instruction, and a number of Neoplatonic commentaries on the verses are extant. The commentary of the Neoplatonist Hierocles of Alexandria on the Golden Verses was first translated into French by André Dacier (1706) and then into English by Nicholas Rowe (1707); a recent English translation is by Schibli (2002). The most recent scholarly edition of the Golden Verses is by Thom (1994), who supplies a new English translation.

Military Transport Aircraft
Military transport aircraft or military cargo aircraft are typically fixed wing and rotary wing cargo aircraft which are used to airlift troops, weapons and other military equipment by a variety of methods to any area of military operations around the surface of the planet, usually outside the commercial flight routes in uncontrolled airspace. Originally derived from bombers, military transport aircraft were used for delivering airborne forces during World War II and towing military gliders. Some military transport aircraft are tasked to perform multi-role duties such as aerial refueling and, rescue missions, tactical, operational and strategic airlifts onto unprepared runways, or those constructed by engineers.

Hung Jury
A hung jury or deadlocked jury is a judicial jury that cannot agree upon a verdict after extended deliberation and is unable to reach the required unanimity or supermajority. This situation can occur only in common law legal systems, because civil law systems either do not use juries at all or provide that the defendant is automatically acquitted if the majority or supermajority required for conviction is not reached during a single, solemn vote.

The Hero with a Thousand Faces
The Hero with a Thousand Faces (first published in 1949) is a work of comparative mythology by Joseph Campbell. In this book, Campbell discusses his theory of the mythological structure of the journey of the archetypal hero found in world myths. Since the publication of The Hero with a Thousand Faces, Campbell's theory has been consciously applied by a wide variety of modern writers and artists. Filmmaker George Lucas acknowledged Campbell's theory in mythology, and its influence on the Star Wars films. The Joseph Campbell Foundation and New World Library issued a new edition of The Hero with a Thousand Faces in July 2008 as part of the Collected Works of Joseph Campbell series of books, audio and video recordings. In 2011, Time (magazine) placed the book in its list of the 100 best and most influential books written in English since the magazine was founded in 1923.

Deformation (Mechanics)
Deformation in continuum mechanics is the transformation of a body from a reference configuration to a current configuration. A configuration is a set containing the positions of all particles of the body. A deformation may be caused by external loads, body forces (such as gravity or electromagnetic forces), or changes in temperature, moisture content, or chemical reactions, etc. Strain is a description of deformation in terms of relative displacement of particles in the body that excludes rigid-body motions. Different equivalent choices may be made for the expression of a strain field depending on whether it is defined with respect to the initial or the final configuration of the body and on whether the metric tensor or its dual is considered. In a continuous body, a deformation field results from a stress field induced by applied forces or is due to changes in the temperature field inside the body. The relation between stresses and induced strains is expressed by constitutive equations, e.g., Hooke's law for linear elastic materials. Deformations which are recovered after the stress field has been removed are called elastic deformations. In this case, the continuum completely recovers its original configuration. On the other hand, irreversible deformations remain even after stresses have been removed. One type of irreversible deformation is plastic deformation, which occurs in material bodies after stresses have attained a certain threshold value known as the elastic limit or yield stress, and are the result of slip, or dislocation mechanisms at the atomic level. Another type of irreversible deformation is viscous deformation, which is the irreversible part of viscoelastic deformation. In the case of elastic deformations, the response function linking strain to the deforming stress is the compliance tensor of the material.

Single-Speed Bicycle
A single-speed bicycle is a type of bicycle with a single gear ratio. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle. There are many types of modern single speed bicycles; BMX bicycles, most bicycles designed for children, cruiser type bicycles, classic commuter bicycles, unicycles, bicycles designed for track racing, fixed-gear road bicycles, and single-speed mountain and cyclocross bikes. Although most fixed-gear bicycles (fixies) are technically single speed, the term single-speed generally refers to a single gear ratio bicycle with a freewheel mechanism to allow it to coast.

Thelema
Thelema (/θəˈliːmə/) is a social or spiritual philosophy derived from Western esotericism. The word thelema is the English transliteration of the Koine Greek noun θέλημα (pronounced [θélɛ:ma]), "will", from the verb θέλω (ethélō): "to will, wish, want or purpose". While Thelema is most often regarded as a religion it is also often called a philosophy. Thelema was developed in the early 1900s by Aleister Crowley, an English writer, mystic, and ceremonial magician. He believed himself to be the prophet of a new age, the Æon of Horus, based upon a spiritual experience that he and his wife, Rose Edith, had in Egypt in 1904. By his account, a possibly non-corporeal or "praeterhuman" being that called itself Aiwass contacted him through Rose and dictated, through Rose, a text known as The Book of the Law or Liber AL vel Legis, which outlined the principles of Thelema. The Thelemic pantheon—a collection of gods and goddesses who either literally exist or serve as symbolic archetypes or metaphors, depending on one's viewpoint—includes a number of deities, primarily a trio adapted from ancient Egyptian religion, who are the three speakers of The Book of the Law: Nuit, Hadit and Ra-Hoor-Khuit. Crowley described these deities as a "literary convenience". The religion is founded on the idea that the 20th century marked the beginning of the Aeon of Horus, in which a new ethical code would be followed: "Do what thou wilt shall be the whole of the Law". This means that adherents of Thelema should seek out and follow their true path, i.e. their True Will. The philosophy also emphasizes the ritual practice of Magick. As Crowley developed the religion, he wrote widely on the topic, as well as producing more "inspired" writings that he collectively termed The Holy Books of Thelema. He also associated Thelemic spiritual practice with concepts rooted in occultism, yoga, and Eastern and Western mysticism, especially the Qabalah. Aspects of Thelema and Crowley's thought in general inspired the development of Wicca and, to a certain degree, the rise of Modern Paganism as a whole, as well as chaos magick and Satanism. Some scholars, such as Hugh Urban, also believe Thelema to have been an influence on the development of Scientology, but others, such as J. Gordon Melton, deny any such connection.

Islamist Shi'ism
Islamist Shi'ism (Persian: تشیع اخوانی‎) is a denomination of Twelver Shia Islam greatly inspired by the Sunni Muslim Brotherhood ideologies and politicized version of Ibn Arabi's mysticism. It sees Islam as a political system and differs from the other mainstream Usuli and Akhbari groups in favoring the idea of formation of Islamist state in occultation of the twelfth Imam. Hadi Khosroshahi was the first person to identify himself as ikhwani (Islamist) Shia. Because of the concept of the hidden Imam, Muhammad al-Mahdi, Shia Islam is inherently secular in the age of occultation, so islamist Shi'ites had to borrow ideas from Sunni islamists and adjust them with Shi'i outlook. Islamism (Persian: اخوانی گری‎) (also often called political Islam or Islamic fundamentalism) is a political ideology which posits that modern states and regions should be reconstituted in constitutional, economic and judicial terms, in accordance with what is conceived as a revival or a return to authentic Islamic practice in its totality. Ideologies dubbed Islamist may advocate a "revolutionary" strategy of Islamizing society through exercise of state power, or alternately a "reformist" strategy to re-Islamizing society through grassroots social and political activism. Islamists may emphasize the implementation of sharia, pan-Islamic political unity, the creation of Islamic states, or the outright removal of non-Muslim influences; particularly of Western or universal economic, military, political, social, or cultural nature in the Muslim world; that they believe to be incompatible with Islam and a form of Western neocolonialism. Some analysts such as Graham E. Fuller describe it as a form of identity politics, involving "support for (Muslim) identity, authenticity, broader regionalism, revivalism, (and) revitalization of the community." The term itself is not popular among many Islamists who believe it inherently implies violent tactics, human rights violations, and political extremism when used by Western mass media. Some authors prefer the term "Islamic activism", while Islamist political figures such as Rached Ghannouchi use the term "Islamic movement" rather than Islamism. Central and prominent figures in 20th-century Islamism include Sayyid Rashid Rida, Hassan al-Banna, Sayyid Qutb, Abul A'la Maududi, Hasan al-Turabi,and Ruhollah Khomeini.
