The Rolling Stones

The Rolling Stones are an English rock band formed in London in 1962. The first settled line-up consisted of Brian Jones (guitar, harmonica), Ian Stewart (piano), Mick Jagger (lead vocals, harmonica), Keith Richards (guitar), Bill Wyman (bass) and Charlie Watts (drums). Stewart was removed from the official line-up in 1963 but continued as an occasional pianist until his death in 1985. Jones departed the band less than a month prior to his death in 1969, having already been replaced by Mick Taylor, who remained until 1975. Subsequently, Ronnie Wood has been on guitar in tandem with Richards. Following Wyman's departure in 1993, Darryl Jones has been the main bassist. Other notable keyboardists for the band have included Nicky Hopkins, active from 1967 to 1982; Billy Preston through the mid 1970s (most prominent on Black and Blue) and Chuck Leavell, active since 1982. The band was first led by Jones but after teaming as the band's songwriters, Jagger and Richards assumed de facto leadership.

Rock (geology)

In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.

Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.

Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.

Classification

At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO₂); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.

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.

Rolling

Rolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding.

Rolling where there is no sliding is referred to as pure rolling. By definition, there is no sliding when the instantaneous velocity of the rolling object in all the points in which it contacts the surface is the same as that of the surface; in particular, for a reference plane in which the rolling surface is at rest, the instantaneous velocity of the point of contact of the rolling object is zero.

In practice, due to small deformations near the contact area, some sliding and energy dissipation occurs. Nevertheless, the resulting rolling resistance is much lower than sliding friction, and thus, rolling objects, typically require much less energy to be moved than sliding ones. As a result, such objects will more easily move, if they experience a force with a component along the surface, for instance gravity on a tilted surface, wind, pushing, pulling, or torque from an engine. Unlike most axially symmetrical objects, the rolling motion of a cone is such that while rolling on a flat surface, its center of gravity performs a circular motion, rather than linear motion. Rolling objects are not necessarily axially-symmetrical. Two well known non-axially-symmetrical rollers are the Reuleaux triangle and the Meissner bodies. The oloid and the sphericon are members of a special family of developable rollers that develop their entire surface when rolling down a flat plane. Objects with corners, such as dice, roll by successive rotations about the edge or corner which is in contact with the surface.

Mick Jagger

Sir Michael Philip "Mick" Jagger Kt (born 26 July 1943) is an English singer, songwriter and actor, best known as the lead vocalist and a co-founder of The Rolling Stones.

Jagger's career has spanned over 50 years, and he has been described as "one of the most popular and influential frontmen in the history of rock & roll". His distinctive voice and performance, along with Keith Richards' guitar style, have been the trademark of the Rolling Stones throughout the career of the band. Jagger gained press notoriety for his admitted drug use and romantic involvements, and was often portrayed as a countercultural figure. In the late 1960s Jagger began acting in films (starting with Performance and Ned Kelly), to mixed reception. In 1985 Jagger released his first solo album, She's the Boss. In early 2009 he joined the electric supergroup SuperHeavy.

In 1989 Jagger was inducted into the Rock and Roll Hall of Fame, and in 2004 into the UK Music Hall of Fame with the Rolling Stones. In 2003 he was knighted for his services to popular music.
