  1. phase

    Phase generally refers to a distinct stage or period in a process of change or development. It can be used in various fields such as physics, where it signifies the position of a point in time or space on a waveform. In the context of matter, it refers to a distinct state or form such as solid, liquid or gas. The term is also used in astronomy to describe the illuminated portion of the moon or a planet from the perspective of an observer.

  1. Phase

    Phase in sinusoidal functions or in waves has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called phase offset or phase difference. Another usage is the fraction of the wave cycle which has elapsed relative to the origin.

Chambers 20th Century Dictionary

  1. Phase

    fāz, n. aspect, appearance, at any stage: an era: the form in which an object or a question presents itself to the mind: the appearance at a given time of the illuminated surface exhibited by a planet—also Phā′sis:—pl. Phas′es.—adj. Phase′less, unchanging. [Gr. phasisphaein, to shine.]

The New Hacker's Dictionary

  1. phase

    1. n. The offset of one's waking-sleeping schedule with respect to the standard 24-hour cycle; a useful concept among people who 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 hours per day on a regular basis. “What's your phase?” “I've been getting in about 8PM lately, but I'm going to wrap around to the day schedule by Friday.” A person who is roughly 12 hours 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. 2. change phase the hard way: To stay awake for a very long time in order to get into a different phase. 3. change phase the easy way: To stay asleep, etc. However, some claim that either staying awake longer or sleeping longer is easy, and that it is shortening your day or night that is really hard (see wrap around). The ‘jet lag’ that afflicts travelers who cross many time-zone boundaries may be attributed to two distinct causes: the strain of travel per se, and the strain of changing phase. Hackers who suddenly find that they must change phase drastically in a short period of time, particularly the hard way, experience something very like jet lag without traveling.
