Pressure

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.

Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa), for example, is one newton per square metre; similarly, the pound-force per square inch (psi) is the traditional unit of pressure in the imperial and US customary systems. Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure and the torr is defined as ¹⁄₇₆₀ of this. Manometric units such as the centimetre of water, millimetre of mercury and inch of mercury are used to express pressures in terms of the height of column of a particular fluid in a manometer.

Definition

Pressure is the amount of force acting per unit area. The symbol for pressure is p or P. The IUPAC recommendation for pressure is a lower-case p. However, upper-case P is widely used. The usage of P vs p depends on the field in which one is working, on the nearby presence of other symbols for quantities such as power and momentum, and on writing style.

Billy Ocean (born Leslie Sebastian Charles; 21 January 1950) is a Trinidadian-born English recording artist who had a string of R&B international pop hits in the 1970s and 1980s. He was the most popular British R&B singer-songwriter of the early to mid-1980s. After scoring his first four UK Top 20 successes, seven years passed before he accumulated a series of transatlantic successes, including three U.S. number ones. In 1985, Ocean won the Grammy Award for Best Male R&B Vocal Performance for his worldwide hit, "Caribbean Queen", and in 1987 was nominated for the Brit Award for Best British Male Artist.

In 2002, the University of Westminster, London, awarded Ocean an honorary doctorate of music. In 2010, Ocean was presented with the Lifetime Achievement Award at the MOBO Awards. On 29 July 2011, Ocean became a Companion of the Liverpool Institute for Performing Arts, presented to him by Sir Paul McCartney. He is a member of the Rastafari movement.

Definition (song)

"Definition" is the first single from Black Star's eponymously titled 1998 album (see 1998 in music). It is produced by Hi-Tek, who samples "The P Is Free" by Boogie Down Productions for the track's beat. In addition, the song's chorus interpolates "Stop the Violence" by Boogie Down Productions. The chorus and the song's lyrics in general deal with the necessity to stop violence in hip hop. The song is an underground hit, but it still reached #60 on the Billboard Hot 100 chart. It is featured on multiples compilations such as Best of Decade I: 1995-2005, Rawkus Records' greatest hits album. Allmusic writer Jason Kaufman considers it to be a "flawless" track.

A reprise of "Definition" titled "RE: DEFinition" can be found on the Black Star album.
