unit cell — n. the smallest unit of structure of a crystal: it has sides parallel to the crystal axes and its exact repetition in three dimensions along these axes generates the space lattice of a given crystal … English World dictionary
Unit sphere — some unit spheres In mathematics, a unit sphere is the set of points of distance 1 from a fixed central point, where a generalized concept of distance may be used; a closed unit ball is the set of points of distance less than or equal to 1 from a … Wikipedia
Unit vector — In mathematics, a unit vector in a normed vector space is a vector (often a spatial vector) whose length is 1 (the unit length). A unit vector is often denoted by a lowercase letter with a hat , like this: (pronounced i hat ). In Euclidean space … Wikipedia
Saturn V Instrument Unit — The Saturn V Instrument Unit is a ring shaped structure fitted to the top of the Saturn V rocket s third stage (S IVB) and the Saturn IB s second stage (S IVB). It was immediately below the SLA (Spacecraft/Lunar Module Adapter) panels that… … Wikipedia
Manned Maneuvering Unit — U.S. astronaut Bruce McCandless uses a manned maneuvering unit The Manned Maneuvering Unit (MMU) is an astronaut propulsion unit which was used by NASA on three space shuttle missions in 1984. The MMU allowed the astronauts to perform untethered… … Wikipedia
Visual display unit — A visual display unit, often called simply a monitor or display, is a piece of electrical equipment which displays images generated from the video output of devices such as computers, without producing a permanent record. A newer monitor… … Wikipedia
Inertial measurement unit — An inertial measurement unit, or IMU, is the main component of inertial guidance systems used in air , space , and watercraft, including guided missiles. An IMU works by sensing motion including the type, rate, and direction of that motion using… … Wikipedia
Bounding volume — A three dimensional model with its bounding box drawn in dashed lines. For building code compliance, see Bounding. In computer graphics and computational geometry, a bounding volume for a set of objects is a closed volume that completely contains … Wikipedia
Quaternions and spatial rotation — Unit quaternions provide a convenient mathematical notation for representing orientations and rotations of objects in three dimensions. Compared to Euler angles they are simpler to compose and avoid the problem of gimbal lock. Compared to… … Wikipedia
Cartesian coordinate system — Illustration of a Cartesian coordinate plane. Four points are marked and labeled with their coordinates: (2, 3) in green, (−3, 1) in red, (−1.5, −2.5) in blue, and the origin (0, 0) in purple. A Cartesian coordinate system specifies each point… … Wikipedia
Euclidean vector — This article is about the vectors mainly used in physics and engineering to represent directed quantities. For mathematical vectors in general, see Vector (mathematics and physics). For other uses, see vector. Illustration of a vector … Wikipedia
