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.

Pressure (Sunscreem song)

"Pressure" is a 1991 dance single recorded by the British techno group Sunscreem, and written and produced by band members Paul Carnell and lead singer Lucia Holm from the act's 1993 set *O₃. "Pressure" was the group's first single release in the United Kingdom, where it peaked at number 60 on the country's pop chart, but it became a major club hit in the United States in wake of the success of "Love U More", where it was released as "Pressure US" with a new remixed version and went to number one on the dance chart for one week in June 1993, their second of three number ones. The re-released version reentered the UK charts afterwards, peaking at number 19 in 1993.

Cornbread (graffiti artist)

Darryl McCray, known by his tagging name, “Cornbread,” is a graffiti artist from Philadelphia, credited with being the first modern graffiti artist. Darryl McCray was born in North Philadelphia in 1953 and raised in Brewerytown, a neighborhood of North Philadelphia. During the late 1960s, he and a group of friends started "tagging" Philadelphia, by writing their nicknames on walls across the city. The movement spread to New York and blossomed into the modern graffiti movement, which reached its peak in the U.S. in the 1980s and then spread to Europe. Since his tagging days, McCray has developed a close relationship with The Philadelphia Mural Arts Program. He is a public speaker and a youth advocate.

Childhood and Corrections Facility

Born in Brewerytown in 1953, Darryl McCray was primarily raised by his mother and grandparents. In 1965, McCray was sent to a juvenile corrections facility called the Youth Development Center (YDC). While at the YDC, McCray adopted the nickname “Cornbread.” McCray complained to the cook of the institution, Mr. Swanson, that he only baked white bread, while McCray preferred his grandmother's cornbread. McCray’s constant badgering inspired Mr. Swanson to start calling McCray “Cornbread,” a nickname that McCray adopted. The YDC was full of Philadelphia gang members who would write their names on the walls of the facility. McCray was never part of a gang, but he would write his new nickname, “Cornbread,” on the walls next to the gang members. He was the first person to tag his own name and not a gang name or symbol.

Cornbread (album)

Cornbread is a jazz album by trumpeter Lee Morgan, released on the Blue Note label in 1967. It features performances by Morgan, Herbie Hancock, Billy Higgins, Jackie McLean, Hank Mobley and Larry Ridley.
