input: Pressure-gradient force

The pressure-gradient force is the force which results when there is a difference in pressure across a surface. In general, a pressure is a force per unit area, across a surface. A difference in pressure across a surface then implies a difference in force, which can result in an acceleration according to Newton's second law of motion, if there is no additional force to balance it. The resulting force is always directed from the region of higher-pressure to the region of lower-pressure. When a fluid is in an equilibrium state (i.e. there are no net forces, and no acceleration), the system is referred to as being in hydrostatic equilibrium. In the case of atmospheres, the pressure gradient force is balanced by the gravitational force, maintaining hydrostatic equilibrium. In Earth's atmosphere, for example, air pressure decreases at altitudes above Earth's surface, thus providing a pressure gradient force which counteracts the force of gravity on the atmosphere.

input: National Women's Day

National Women's Day is a South African public holiday celebrated annually on 9 August. The day commemorates the 1956 march of approximately 20 000 women to the Union Buildings in Pretoria to petition against the country's pass laws that required South Africans defined as ''black'' under The Population Registration Act to carry an internal passport, known as a pass, that served to maintain population segregation, control urbanisation, and manage migrant labour during the apartheid era. The first National Women's Day was celebrated on 9 August 1994. In 2006, a reenactment of the march was staged for its 50th anniversary, with many of the 1956 march veterans.

input: Promotion (chess)

Promotion is a chess rule that requires a pawn that reaches its eighth rank to be immediately replaced by the player's choice of a queen, knight, rook, or bishop of the same color . The new piece replaces the pawn, as part of the same move. The choice of new piece is not limited to pieces previously captured , thus promotion can result in a player owning, for example, two or more queens despite starting the game with one. Pawn promotion, or the threat of it, often decides the result in an endgame. Since the queen is the most powerful piece, the vast majority of promotions are to a queen. Promotion to a queen is often called queening; promotion to any other piece is referred to as underpromotion (Golombek 1977).
