quadrature
Making something square
Quadrature refers to the process of finding a square equal in area to a given figure—the classical problem of "squaring the circle." In mathematics and physics, quadrature means calculating an integral or the area under a curve.
In astronomy, quadrature describes the position of a celestial body when it forms a 90-degree angle with the sun as seen from Earth: The moon is in quadrature at its first and third quarters.
In electronics, quadrature refers to signals 90 degrees out of phase with each other.
