Phases
(gcide) | Phase \Phase\ (f[=a]z), n.; pl. Phases (f[=a]z"[e^]z). [NL.
phasis, Gr. fa`sis, fr. fai`nein to make to appear: cf. F.
phase. See Phenomenon, Phantom, and Emphasis.]
1. That which is exhibited to the eye; the appearance which
anything manifests, especially any one among different and
varying appearances of the same object.
[1913 Webster]
2. Any appearance or aspect of an object of mental
apprehension or view; as, the problem has many phases.
[1913 Webster]
3. (Astron.) A particular appearance or state in a regularly
recurring cycle of changes with respect to quantity of
illumination or form of enlightened disk; as, the phases
of the moon or planets. See Illust. under Moon.
[1913 Webster]
4. (Physics) Any one point or portion in a recurring series
of changes, as in the changes of motion of one of the
particles constituting a wave or vibration; one portion of
a series of such changes, in distinction from a contrasted
portion, as the portion on one side of a position of
equilibrium, in contrast with that on the opposite side.
[1913 Webster]
5. (Phys. Chem.) A homogenous, physically distinct portion of
matter in a system not homogeneous; as, the three phases,
ice, water, and aqueous vapor; in a mixture of gasoline
and water, the gasoline will settle as the upper phase. A
phase may be either a single chemical substance or a
mixture, as of gases.
[Webster 1913 Suppl.]
6. (Zool.) In certain birds and mammals, one of two or more
color variations characteristic of the species, but
independent of the ordinary seasonal and sexual
differences, and often also of age. Some of the herons
which appear in white and colored phases, and certain
squirrels which are sometimes uniformly blackish instead
of the usual coloration, furnish examples. Color phases
occur also in other animals, notably in butterflies.
[Webster 1913 Suppl.]
7. (Physics) the relation at any instant of any cyclically
varying physical quantity, such as voltage in an A.C.
circuit, an electromagnetic wave, a sound wave, or a
rotating object, to its initial value as expressed as a
fractional part of the complete cycle. It is usually
expressed in angular measure, the complete cycle being
360[deg]. Such periodic variations are generally well
represented by sine curves; and phase relations are shown
by the relative positions of the crests and hollows of
such curves. Magnitudes which have the same phase are said
to be in phase.
Note: The concept of phase is also applied generally to any
periodically varying phenomenon, as the cycle of
daylight. One person who sleeps during the day and
another who sleeps at night may be said to be out of
phase with each other.
[PJC]
8. Specifically: (Elec.) The relation at any instant of a
periodically varying electric magnitude, as electro-motive
force, a current, etc., to its initial value as expressed
in factorial parts of the complete cycle. It is usually
expressed in angular measure, the cycle being four right
angles, or 360[deg].

Emphases
(gcide) | emphasis \em"pha*sis\ ([e^]m"f[.a]*s[i^]s), n.; pl. Emphases
([e^]m"f[.a]*s[=e]z). [L., fr. Gr. 'e`mfasis significance,
force of expression, fr. 'emfai`nein to show in, indicate;
'en in + fai`nein to show. See In, and Phase.]
1. (Rhet.) A particular stress of utterance, or force of
voice, given in reading and speaking to one or more words
whose signification the speaker intends to impress
specially upon his audience.
[1913 Webster]
The province of emphasis is so much more important
than accent, that the customary seat of the latter
is changed, when the claims of emphasis require it.
--E. Porter.
[1913 Webster]
2. A peculiar impressiveness of expression or weight of
thought; vivid representation, enforcing assent; as, to
dwell on a subject with great emphasis.
[1913 Webster]
External objects stand before us . . . in all the
life and emphasis of extension, figure, and color.
--Sir W.
Hamilton.
[1913 Webster]
3. a special attention given to, or extra importance attached
to, something; as, a guided tour of Egypt with emphasis on
the monuments along the Nile.
[PJC]
4. something to which great importance is attached; as, the
need for increased spending on education was the emphasis
of his speech.
