phase,

in astronomy, the measure of how much of the illuminated surface of a planet or satellite can be seen from a point at a distance from that body; the term is most often used to describe the moon as seen from the earth. When the moon is between the earth and the sun, we cannot see the lighted half at all, and the moon is said to be new. For a few days before and after the new moon we can see a small part of the lighted half, which appears as a crescent with the horns, or cusps, pointing away from the sun. When the moon has completed half its orbit from new moon to new moon, it is on the opposite side of the earth from the sun and we see the entire lighted half; this phase is called the full moon. When the moon is at quadraturequadrature,
in astronomy, arrangement of two celestial bodies at right angles to each other as viewed from a reference point. If the reference point is the earth and the sun is one of the bodies, a planet is in quadrature when its elongation is 90°.
..... Click the link for more information. with the sun, having completed either one quarter or three quarters of its orbit from new moon to new moon, half the lighted side is visible; this phase is called the half-moon. The half-moon between the new moon and the full moon is known as the first quarter and that between the full moon and new moon is known as the last quarter. Between the first quarter and the full moon and between the full moon and the last quarter we see more than half the lighted side; this phase is called gibbous. Of the planets, only Mercury and Venus, whose orbits pass between the earth and sun, show all the phases that the moon shows; the other planets are always either gibbous or full.

Phase (periodic phenomena)

The fractional part of a period through which the time variable of a periodic quantity (alternating electric current, vibration) has moved, as measured at any point in time from an arbitrary time origin. In the case of a sinusoidally varying quantity, the time origin is usually assumed to be the last point at which the quantity passed through a zero position from a negative to a positive direction.

In comparing the phase relationships at a given instant between two time-varying quantities, the phase of one is usually assumed to be zero, and the phase of the other is described, with respect to the first, as the fractional part of a period through which the second quantity must vary to achieve a zero of its own (see illustration). In this case, the fractional part of the period is usually expressed in terms of angular measure, with one period being equal to 360° or 2π radians. See Phase-angle measurement, Sine wave

An illustration of the meaning of phase for a sinusoidal wave

phase

(fayz) 1. The appearance of the illuminated surface of the Moon or a planet at a particular time during its orbit or of the Sun during an eclipse. Specifically it is the fraction of the object's apparent disk (taken to be circular) that is illuminated. Unlike the superior planets, Mercury and Venus can exhibit those phases in which half or less of the illuminated hemisphere is visible from Earth. See also phases, lunar. 2. The fraction of one complete cycle of a regularly recurring quantity that has elapsed with respect to a fixed datum point. The phase difference, ⊂, is the difference in phase between two electrical oscillations, wavetrains, etc., of the same frequency (i.e. coherent signals) and is usually expressed in terms of part of one complete cycle or wavelength. ‘Phase difference’ is often referred to simply as ‘phase’, as it is when considering the coherent signals in the two arms of a radio interferometer.

Phase

the argument of the function cos (ωt+ φ), describing a harmonic oscillatory process, where ω is the angular frequency, t is the time, and φ is the initial phase of oscillations, that is, the phase at the initial time t = 0. The phase can be determined with an accuracy up to the value of an arbitrary term that is a multiple of 2π. Usually, the only values of interest are the phase differences in various harmonic processes. For oscillations that have the same frequency, the phase difference is always equal to the difference between the initial phases φ₁ – φ₂ and does not depend on the time reference point. For oscillations that have differing frequencies ω_l and ω₂, the phase relationships are characterized by the reduced phase difference

which similarly is not dependent on the time reference point. The auditory perception of the direction from which a sound approaches is associated with the difference in the phase of acoustic vibrations arriving at each ear.

Phase

in thermodynamics, a state of thermodynamic equilibrium of a substance, the physical properties of which differ from those of other equilibrium states—that is, other phases—of the same substance (seeEQUILIBRIUM, THERMODYNAMIC). A nonequilibrium metastable state of a substance is sometimes called a phase or, more explicitly, a metastable phase.

A transition of a substance from one phase to another, which is called a phase transition, is associated with a qualitative change in the properties of the substance. For example, the gaseous, liquid, and crystalline states, or phases, of a substance are substantially different with respect to the nature of the motion of particles (molecules) and the presence or absence of ordered structure (seeSTATES OF AGGREGATION). At high temperatures and pressures, a substance undergoes a transition to the plasma state. Various crystalline phases may differ from one another in, for example, electrical conductivity, the presence of an electric or magnetic moment, the type of crystal structure, and the existence of superconductivity. Various liquid phases may differ from one another in, for example, the concentration of components, the presence or absence of superfluidity (as in liquid ³He and ⁴He; seeQUANTUM FLUID), and the anisotropy of elastic and electrical properties (as in liquid crystals).

In most cases, phases are spatially homogeneous. However, there are some exceptions, such as ferromagnets in weak magnetic fields (seeDOMAINS) and the mixed state of type II superconductors (seeSUPERCONDUCTIVITY).

phase

(1)The offset of one's waking-sleeping schedule with respectto the standard 24-hour cycle; a useful concept among peoplewho often work at night and/or according to no fixed schedule.It is not uncommon to change one's phase by as much as 6 hoursper day on a regular basis. "What's your phase?" "I've beengetting in about 8 P.M. lately, but I'm going to wrap aroundto the day schedule by Friday." A person who is roughly 12hours out of phase is sometimes said to be in "night mode".(The term "day mode" is also (but less frequently) used,meaning you're working 9 to 5 (or, more likely, 10 to 6).)The act of altering one's cycle is called "changing phase";"phase shifting" has also been recently reported from Caltech.

phase

(2)"change phase the hard way": To stay awake for a very longtime in order to get into a different phase.

phase

(3)"change phase the easy way": To stay asleep, etc. However,some claim that either staying awake longer or sleeping longeris easy, and that it is *shortening* your day or night that isreally hard (see wrap around). The "jet lag" that afflictstravelers who cross many time-zone boundaries may beattributed to two distinct causes: the strain of travel perse, and the strain of changing phase. Hackers who suddenlyfind that they must change phase drastically in a short periodof time, particularly the hard way, experience something verylike jet lag without travelling.
