twin
\Twin\, n. 1. One of two produced at a birth, especially by
an animal that ordinarily brings forth but one at a birth; -- used chiefly
in the plural, and applied to the young of beasts as well as to human
young.
2. pl. (Astron.) A sign and constellation of the zodiac; Gemini. See
Gemini.
3. A person or thing that closely resembles another.
4. (Crystallog.) A compound crystal composed
of two or more crystals, or parts of crystals, in reversed position
with reference to each other.
Note: The relative position of the parts of a twin may be explained
by supposing one part to be revolved 180[deg] about a certain axis (called
the twinning axis), this axis being normal to a plane (called the twinning
plane) which is usually one of the fundamental planes of the crystal.
This revolution brings the two parts into parallel position, or vice
versa. A contact twin is one in which the parts are united by a plane
surface, called the composition face, which is usually the same as the
twinning plane. A penetration twin is one in which the parts interpenetrate
each other, often very irregularly. Twins are also called, according
to form, cruciform, geniculated, etc.
