Editing Phase (section)

==Science==
*[[State of matter]], or phase, one of the distinct forms in which matter can exist
*[[Phase (matter)]], a region of space throughout which all physical properties are essentially uniform
*[[Phase space]], a mathematical space in which each possible state of a physical system is represented by a point {{Ndash}}also referred to as a "microscopic state"
**[[Phase space formulation]], a formulation of quantum mechanics in phase space
*[[Phase (waves)]], the position of a point in time (an instant) on a waveform cycle
**[[Instantaneous phase]], generalization for both cyclic and non-cyclic phenomena
*[[AC phase]], the phase offset between alternating current electric power in multiple conducting wires
**[[Single-phase electric power]], distribution of AC electric power in a system where the voltages of the supply vary in unison
**[[Three-phase electric power]], a common method of AC electric power generation, transmission, and distribution
*[[Phase problem]], the loss of information (the phase) from a physical measurement
*[[Phase factor]], a complex scalar used in quantum mechanics
*In [[continuous Fourier transform]], the angle of a complex coefficient representing the phase of one sinusoidal component
*The argument or angle of [[Complex number|complex numbers]] is sometimes called the phase
