Existential quantification

In predicate logic, an existential quantification is a type of quantifier, a logical constant which is interpreted as "there exists", "there is at least one", or "for some".

It is usually denoted by the turned E (∃) logical operator symbol, which, when used together with a predicate variable, is called an existential quantifier ("∃x" or "∃(x)"). Existential quantification is distinct from universal quantification ("for all"), which asserts that the property or relation holds for all members of the domain.

Symbols are encoded U+2203 ∃ THERE EXISTS (HTML ∃ · ∃ · as a mathematical symbol) and U+2204 ∄ THERE DOES NOT EXIST (HTML ∄).

Basics

Consider a formula that states that some natural number multiplied by itself is 25.

This would seem to be a logical disjunction because of the repeated use of "or". However, the "and so on" makes this impossible to integrate and to interpret as a disjunction in formal logic. Instead, the statement could be rephrased more formally as

History

Masada arrived in America at age 14. He worked multiple jobs in Hollywood to support his family back home, while also performing on the comedy circuit to build his stand-up career. Despite the fact that he was living in a garage and barely spoke English, he combined Persian and Hebrew and soon was working with professional comedians like Richard Pryor, David Letterman, Jay Leno, and Redd Foxx. Masada's father told him, “Making people laugh is the greatest Mitzvah of all.” In 1979, after a dispute over club owners refusing to pay comedians, a then 16-year-old Masada decided to open a new venue for comedians to perform. After obtaining a loan of $10,000 from Neal Israel, he opened the Laugh Factory in a building formerly belonging to Groucho Marx.Richard Pryor was the first comedian to perform at the club.

Some Girls

Some Girls is the 14th British and 16th American studio album by the Rolling Stones, released in 1978 on Rolling Stones Records. It reached number one on the Billboard 200 album chart, and became the band's top selling album in the United States, certified by the RIAA as having six million copies sold as of 2000. It was a major critical success, becoming the only Rolling Stones album to be nominated for a Grammy in the Album of the Year category. Many reviewers called it a classic return to form and their best album since 1972's Exile on Main St.

History

By 1976, the Rolling Stones' popularity was in decline as the charts were dominated by disco music and newer bands such as Aerosmith and Kiss. In the UK, the punk rock movement was a rising force and made most artists connected with the 1960s era seem obsolete. The group had also failed to produce a critically acclaimed album since 1972's Exile On Main St.

At least as important for the band's re-invigoration was the addition of Ronnie Wood to the line-up, as Some Girls was the first album recorded with him as a full member. His guitar playing style meshed with that of Keith Richards and slide guitar playing would become one of the band's hallmarks. Not only did his unconventional uses of the instrument featured prominently on Some Girls he also contributed to the writing process. In addition, Jagger, who had learned to play guitar over the previous decade, contributed a third guitar part to many songs. This gave songs like "Respectable" a three-guitar line-up.

Film festival

A film festival is an organized, extended presentation of films in one or more cinemas or screening venues, usually in a single city or region. Increasingly, film festivals show some films outdoors. Films may be of recent date and, depending upon the festival's focus, can include international and domestic releases. Some festivals focus on a specific film-maker or genre (e.g., film noir) or subject matter (e.g., horror film festivals). A number of film festivals specialise in short films of a defined maximum length. Film festivals are typically annual events. Some film historians do not consider Film Festivals as official releases of film, like Jerry Beck. The best known film festivals are the Venice Film Festival, the Cannes Film Festival, the Toronto Film Festival, Sundance Film Festival, and the Berlin International Film Festival, the latter being the largest film festival worldwide, based on attendance. The Venice Film Festival is the oldest major festival. The Melbourne International Film Festival is the largest film festival in the Southern Hemisphere and one of the oldest in the world. A 2013 study found 3,000 active films festivals worldwide—active defined as having held an event in the previous 24 months.
