De revolutionibus orbium coelestium (English translation: On the Revolutions of the Heavenly Spheres) is the seminal work on the heliocentric theory of the astronomer Nicolaus Copernicus (1473–1543) of the Polish Renaissance. The book, first printed in 1543 in Nuremberg, Holy Roman Empire, offered an alternative model of the universe to Ptolemy's geocentric system, which had been widely accepted since ancient times. History Copernicus initially outlined his system in a short, untitled, anonymous manuscript that he distributed to several friends, referred to as the Commentariolus. A physician's library list dating to 1514 includes a manuscript whose description matches the Commentariolus, so Copernicus must have begun work on his new system by that time. Most historians believe that he wrote the Commentariolus after his return from Italy, possibly only after 1510. At this time, Copernicus anticipated that he could reconcile the motion of the Earth with the perceived motions of the planets easily, with fewer motions than were necessary in the Alfonsine Tables, the version of the Ptolemaic...

Socratic questioning (or Socratic maieutics) was named after Socrates. He used an educational method that focused on discovering answers by asking questions from his students. According to Plato, who was one of his students, Socrates believed that "the disciplined practice of thoughtful questioning enables the scholar/student to examine ideas and be able to determine the validity of those ideas". Plato described this rigorous method of teaching to explain that the teacher assumes an ignorant mindset in order to compel the student to assume the highest level of knowledge. Thus, a student has the ability to acknowledge contradictions, recreate inaccurate or unfinished ideas and critically determine necessary thought. Socratic questioning is a form of disciplined questioning that can be used to pursue thought in many directions and for many purposes, including: to explore complex ideas, to get to the truth of things, to open up issues and problems, to uncover assumptions, to analyze concepts, to distinguish what we know from what we do not know, to follow out logical consequences of thought or to control discussions. Socratic questioning is based on the foundation...

Avant-garde jazz (also known as avant-jazz and experimental jazz) is a style of music and improvisation that combines avant-garde art music and composition with jazz. It originated in the early 1950s and developed through to the late 1960s. Originally synonymous with free jazz, much avant-garde jazz was distinct from that style. History 1950s Avant-garde jazz originated in the mid- to late 1950s among a group of improvisors who rejected the conventions of bebop and post bop in an effort to blur the division between the written and the spontaneous. Ornette Coleman and Cecil Taylor led the way, soon to be joined by John Coltrane. Some would come to apply it differently from free jazz, emphasizing structure and organization by the use of composed melodies, shifting but nevertheless predetermined meters and tonalities, and distinctions between soloists and accompaniment. 1960s In Chicago, the Association for the Advancement of Creative Musicians began pursuing their own variety of avant-garde jazz. The AACM musicians (Muhal Richard Abrams, Anthony...

Counterinsurgency (COIN) is "the totality of actions aimed at defeating irregular forces". The Oxford English Dictionary defines counterinsurgency as any "military or political action taken against the activities of guerrillas or revolutionaries" and can be considered war by a state against a non-state adversary. Insurgency and counterinsurgency campaigns have been waged since ancient history. However, modern thinking on counterinsurgency was developed during decolonization. Within the military sciences, counterinsurgency is one of the main operational approaches of irregular warfare.During insurgency and counterinsurgency, the distinction between civilians and combatants is often blurred. Counterinsurgency may involve attempting to win the hearts and minds of populations supporting the insurgency. Alternatively, it may be waged in an attempt to intimidate or eliminate civilian populations suspected of loyalty to the insurgency through indiscriminate violence. Models Counterinsurgency is normally conducted as a combination of conventional military operations and other means, such as demoralization...

A funnel cloud is a funnel-shaped cloud of condensed water droplets, associated with a rotating column of wind and extending from the base of a cloud (usually a cumulonimbus or towering cumulus cloud) but not reaching the ground or a water surface. A funnel cloud is usually visible as a cone-shaped or needle like protuberance from the main cloud base. Funnel clouds form most frequently in association with supercell thunderstorms, and are often, but not always, a visual precursor to tornadoes. Funnel clouds are visual phenomena, these are not the vortex of wind itself. "Classic" funnel clouds If a funnel cloud touches the surface the feature is considered a tornado, although ground level circulations begin before the visible condensation cloud appears. Most tornadoes begin as funnel clouds, but some funnel clouds do not make surface contact and these cannot be counted as tornadoes from the perspective of a naked eye observer, even as tornadic circulations of some intensity almost always are detectable when low-level radar observations are available. Also, tornadoes occur...

Félix Lope de Vega y Carpio ( LOH-pay dee VAY-gə, Spanish: [ˈfeliɣz ˈlope ðe ˈβeɣa i ˈkaɾpjo]; 25 November 1562 – 27 August 1635) was a Spanish playwright, poet, and novelist. He was one of the key figures in the Spanish Golden Age of Baroque literature. His reputation in the world of Spanish literature is second only to that of Miguel de Cervantes, while the sheer volume of his literary output is unequalled, making him one of the most prolific authors in the history of literature. He was nicknamed "The Phoenix of Wits" and "Monster of Nature" (in Spanish: Fénix de los Ingenios, Monstruo de Naturaleza) by Cervantes because of his prolific nature. Lope de Vega renewed the Spanish theatre at a time when it was starting to become a mass cultural phenomenon. He defined its key characteristics...
