Dubai International Airport is situated in the Al Garhoud district, 2.5 nautical miles (4.6 km; 2.9 mi) east [2] of the city centre of Dubai and spread over an area of 7,200 acres (2,900 ha) of land. [12] Terminal 3 is the second-largest building in the world by floor space and the largest airport terminal in the world. [13] In July 2019, Dubai International airport installed the largest solar ...
Differential form. In mathematics, differential forms provide a unified approach to define integrands over curves, surfaces, solids, and higher-dimensional manifolds. The modern notion of differential forms was pioneered by Élie Cartan. It has many applications, especially in geometry, topology and physics.
Space form. In mathematics, a space form is a complete Riemannian manifold M of constant sectional curvature K. The three most fundamental examples are Euclidean n -space, the n -dimensional sphere, and hyperbolic space, although a space form need not be simply connected .
On 17 January 2020, the Space Force announced that its combat utility uniform would be the same Operational Camouflage Pattern (OCP) uniform as when it was Air Force Space Command. The full-color United States flag is worn on the left side of the uniform. The name tape, branch tape, and rank are embroidered in space blue, distinguishing it from ...
Dual space. In mathematics, any vector space has a corresponding dual vector space (or just dual space for short) consisting of all linear forms on together with the vector space structure of pointwise addition and scalar multiplication by constants. The dual space as defined above is defined for all vector spaces, and to avoid ambiguity may ...
The Society is dedicated to the exploration of the Solar System, the search for near-Earth objects, and the search for extraterrestrial life. [4] The society's mission is stated as: "Empowering the world’s citizens to advance space science and exploration." [5] The Planetary Society is a strong advocate for space funding and missions of exploration within NASA. They lobby Congress and engage ...
Interstellar ice. Interstellar ice consists of grains of volatiles in the ice phase that form in the interstellar medium. Ice and dust grains form the primary material out of which the Solar System was formed. Grains of ice are found in the dense regions of molecular clouds, where new stars are formed. Temperatures in these regions can be as ...
Polyurethane ( / ˌpɒliˈjʊərəˌθeɪn, - jʊəˈrɛθeɪn /; [1] often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials.
