Atomium Culture
The Atomium ( , , ) is a landmark building in Brussels, Belgium, originally constructed for the 1958 Brussels World's Fair (Expo '58). It is located on the Heysel/Heizel Plateau in Laeken (northern part of the City of Brussels), where the exhibition took place. Nowadays, it is the city's most popular tourist attraction, and serves as a museum, an art centre and a cultural place. Designed by the engineer André Waterkeyn and the architects André and Jean Polak, it stands tall. Its nine stainless steel clad spheres are connected in the shape of a unit cell that could represent an iron crystal magnified 165 billion times. Steel tubes connecting the spheres enclose stairs, escalators and an elevator (in the central, vertical tube) to allow access to the six visitable spheres, which contain exhibit halls and other public spaces. The top sphere includes a restaurant with a panoramic view of Brussels. The building was completely renovated between 2004 and 2006 by the companies Ja ...

Laeken
() or () is a residential suburb in the north-western part of the Brussels-Capital Region, Belgium. It belongs to the List of municipalities of the Brussels-Capital Region, municipality of the City of Brussels and is mostly identified by the Belgian postal code: 1020. Prior to 1921, it was a separate municipality. Toponymy Etymology The name ''Laeken'' ( nl, Laken, link=no) derives from the Germanic ''Lacha'' or ''Lache'' ("water", "lake"), because the Molenbeek brook at the time formed a network of ponds at this height. The oldest mention of the village is in a diploma from 1080, where the name ''Gilbert de Lacha'' appears. There is also the mention ''Lachus'' in 1117. Main sights Royal Palace The Palace of Laeken, Royal Palace of Laeken, official home of the Monarchy of Belgium, Belgian Royal Family, is situated in Laeken. The palace was built in 1782–1784 by the French architect and urbanist Charles de Wailly. It was partly destroyed by fire in 1890, and was rebuil ...

Crystal Structure
In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystal, crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of Three-dimensional space (mathematics), three-dimensional space in matter. The smallest group of particles in the material that constitutes this repeating pattern is the unit cell of the structure. The unit cell completely reflects the symmetry and structure of the entire crystal, which is built up by repetitive Translation (geometry), translation of the unit cell along its principal axes. The translation vectors define the nodes of the Bravais lattice. The lengths of the principal axes, or edges, of the unit cell and the angles between them are the lattice constants, also called ''lattice parameters'' or ''cell parameters''. The symmetry properties of the crystal are described by the con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Physics
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields. This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements. History The history of nuclear physics as a discipl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multilingualism
Multilingualism is the use of more than one language, either by an individual speaker or by a group of speakers. It is believed that multilingual speakers outnumber monolingual speakers in the world's population. More than half of all Europeans claim to speak at least one language other than their mother tongue; but many read and write in one language. Multilingualism is advantageous for people wanting to participate in trade, globalization and cultural openness. Owing to the ease of access to information facilitated by the Internet, individuals' exposure to multiple languages has become increasingly possible. People who speak several languages are also called polyglots. Multilingual speakers have acquired and maintained at least one language during childhood, the so-called first language (L1). The first language (sometimes also referred to as the mother tongue) is usually acquired without formal education, by mechanisms about which scholars disagree. Children acquirin ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Atom
Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics, as if they were tennis balls for example, is not possible due to quantum effects. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, then the atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively – such atoms are called ions. The electrons of an atom are a ...

Brussels Metro
The Brussels Metro (french: Métro de Bruxelles, nl, Brusselse metro) is a rapid transit system serving a large part of the Brussels-Capital Region of Belgium. It consists of four conventional metro lines and three ''premetro'' lines. The metro-grade lines are M1, M2, M5, and M6 with some shared sections, covering a total of , with 59 metro-only stations. The ''premetro'' network consists of three tram lines (T3, T4, and T7) that partly travel over underground sections that were intended to be eventually converted into metro lines. Underground stations in the ''premetro'' network use the same design as metro stations. A few short underground tramway sections exist, so there is a total of of underground metro and tram network. There are a total of 69 metro and ''premetro'' stations as of 2011. Most of the common section of the first two metro lines (between De Brouckère metro station and Schuman station) was inaugurated on 17 December 1969 as ''premetro'' tramways, converte ...

Panorama
A panorama (formed from Greek πᾶν "all" + ὅραμα "view") is any wide-angle view or representation of a physical space, whether in painting, drawing, photography, film, seismic images, or 3D modeling. The word was originally coined in the 18th century by the English (Irish descent) painter Robert Barker to describe his panoramic paintings of Edinburgh and London. The motion-picture term ''panning'' is derived from ''panorama''. A panoramic view is also purposed for multimedia, cross-scale applications to an outline overview (from a distance) along and across repositories. This so-called "cognitive panorama" is a panoramic view over, and a combination of, cognitive spaces used to capture the larger scale. History The device of the panorama existed in painting, particularly in murals, as early as 20 A.D., in those found in Pompeii, as a means of generating an immersive "panoptic" experience of a vista. Cartographic experiments during the Enlightenment era prec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevator
An elevator or lift is a wire rope, cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or deck (building), decks of a building, watercraft, vessel, or other structure. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist (device), hoist, although some pump hydraulic fluid to raise a cylindrical piston like a hydraulic jack, jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English, such as Japanese, may refer to elevators by loanwords based on either ''elevator'' or ''lift''. Due to wheelchair access laws, elevators are ...
