See Gemini. 3. A person or thing that closely resembles another. 4. <chemistry> A compound crystal composed of two or more crystals, or parts of crystals, in reversed position with reference to each other. 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. Source: Websters Dictionary (01 Mar 1998) |

| twin |
The term twin most notably refers to two individuals (or one of two individuals) who have shared the same uterus (womb) and are usually, but not necessarily, born on the same day. A fetus alone in the womb is called a singleton. Due to the limited size of the mother's womb, multiple pregnancy is much less likely to carry to full term than singleton birth. ...
