Atomium (J
The Atomium ( , , ) is a landmark modernist building in Brussels, Belgium, originally constructed as the centrepiece of the 1958 Brussels World's Fair ( Expo 58). Designed by the engineer André Waterkeyn and the architects André and Jean Polak as a tribute to scientific progress, as well as to symbolise Belgian engineering skills at the time, it is located on the Heysel/Heizel Plateau in Laeken (northern part of the City of Brussels), where the exhibition took place. It is the city's most popular tourist attraction, and serves as a museum, an art centre and a cultural destination. The Atomium stands tall, making it one of the tallest structures in Belgium. 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 e ...

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 ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Escalator
An escalator is a moving staircase which carries people between floors of a building or structure. It consists of a motor-driven chain of individually linked steps on a track which cycle on a pair of tracks which keep the step tread horizontal. Escalators are often used around the world in places where lifts would be impractical, or they can be used in conjunction with them. Principal areas of usage include department stores, shopping malls, airports, transit systems (railway/railroad stations), convention centers, hotels, arenas, stadiums and public buildings. Escalators have the capacity to move large numbers of people. They have no waiting interval (except during very heavy traffic). They can be used to guide people toward main exits or special exhibits and may be weatherproofed for outdoor use. A non-functional escalator can function as a normal staircase, whereas many other methods of transport become useless when they break down or lose power. Design, components ...

Crystal
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and "rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third category of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
