The Kaaba is a cuboid -shaped structure made of stones. It is approximately 15 m (49 ft 3 in) high with sides measuring 12 m (39 ft 4 in) × 10.5 m (34 ft 5 in) wide [88] (Hawting states 10 m (32 ft 10 in). [89] Inside the Kaaba, the floor is made of marble and limestone.
CubeSat. Ncube-2, a Norwegian CubeSat (10 cm (3.9 in) cube) A CubeSat is a class of small satellite with a form factor of 10 cm (3.9 in) cubes. [1] CubeSats have a mass of no more than 2 kg (4.4 lb) per unit, [2] and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are deployed into orbit from ...
A 12-color Megaminx in a star-pattern arrangement. The Megaminx or Mégaminx ( / ˈmɛɡəmɪŋks /, / ˈmeɪ -/) is a dodecahedron -shaped puzzle similar to the Rubik's Cube. It has a total of 50 movable pieces to rearrange, compared to the 20 movable pieces of the Rubik's Cube.
The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices. The cube is also a square parallelepiped, an equilateral cuboid, a right rhombohedron, and a 3-zonohedron. It is a regular square prism in three orientations, and a trigonal trapezohedron in four orientations.
The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3 . The cube is also the number multiplied by its square : n3 = n × n2 = n × n × n. The cube function is the function x ↦ x3 (often denoted y = x3) that maps a number to its cube. It is an odd function, as.
List of CubeSats. The following is a list of CubeSats, nanosatellites used primarily by universities for research missions, typically in low Earth orbits. Some CubeSats became their country's first national satellite. The extensive Nanosatellite and CubeSat Database lists nearly 4,000 CubeSats and NanoSats have been launched since 1998. [1]
Capsid. Schematic of a cytomegalovirus. Illustration of geometric model changing between two possible capsids. A similar change of size has been observed as the result of a single amino-acid mutation [1] A capsid is the protein shell of a virus, enclosing its genetic material. It consists of several oligomeric (repeating) structural subunits ...
Unique identifier. A unique identifier ( UID) is an identifier that is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. [1] The concept was formalized early in the development of computer science and information systems. In general, it was associated with an atomic data type .
