The Science Museum holds over 300,000 items, including such famous items as Stephenson's Rocket, Puffing Billy (the oldest surviving steam locomotive), the first jet engine, a remake of Francis Crick and James Watson's model of DNA, some of the earliest remaining steam engines, a working example of Charles Babbage's Difference engine (and the latter, preserved half brain), the first prototype (draft model) of the 10,000-year Clock of the Long Now, and documentation of the first typewriter. It also contains hundreds of interactive exhibits. A recent addition is the IMAX 3D Cinema showing science and nature documentaries, most of them in 3-D, and the Wellcome Wing which focuses on digital technology.
The museum houses some of the many objects collected by Henry Wellcome that have to do with medicine. The fourth floor exhibit is called "Glimpses of Medical History", with reconstructions and dioramas of the history of medicine. The fifth floor gallery is called "Science and the Art of Medicine", with exhibits of medical instruments and practices from ancient days and from many countries. The collection has a lot of items from clinical medicine, the biosciences, and public health. The museum is a member of the London Museums of Health & Medicine.
The Science Museum has a dedicated library, and until the 1960s was Britain's National Library for Science, Medicine and Technology. It holds runs of periodicals, early books and manuscripts, and is used by scholars worldwide. It has for a number of years been run in conjunction with the Library of Imperial College, but in 2007 the Library was divided over two sites. Histories of science and biographies of scientists are still kept at the Imperial College in London. The rest of the collection which includes original scientific works and archives are now located in Wroughton, Wiltshire.
Some 170,000 items which are not on current display are stored at Blythe House in West Kensington. Blythe House also houses facilities including a conservation laboratory, a photographic studio, and a quarantine area where newly-arrived items are looked at.
The Science Museum is made up of a number of galleries, some of which are permanent, and some of which are temporary.
The East Hall is the first area that most visitors see as they enter the building, going up through three floors. On the ground, the area is mostly filled with famous steam engines of various sorts, including the oldest surviving James Watt beam engine, which together tell the story of the British industrial revolution. Up in the air, hung from the ceiling is a big metal ring, the inside of which is covered in white LEDs which form patterns and display messages typed into kiosks by visitors in the Energy gallery.
"Exploring Space" is a historical gallery, filled with rockets and exhibits that tell the story of human space exploration and the benefits that space exploration has brought us (particularly in the world of telecommunications).
"Making the Modern World" is a relatively new gallery, in which some of the museum's most iconic objects, including Stephenson's Rocket and an Apollo spacecraft, are imaginatively displayed along a timeline chronicling man's technological achievements.
"Flight" is another longstanding gallery, up towards the western end of the third floor. Contained in the gallery are several full sized aeroplanes and helicopters, including Alcock and Brown's transatlantic Vickers Vimy (1919), Spitfire and Hurricane fighters, as well as numerous aero-engines and a cross-section of a Boeing 747.
One of the most popular galleries in the museum is the interactive Launchpad gallery. Redesigned and reopened in November 2007, the new look gallery houses over 50 interactive exhibits illustrating many different concepts in physical science. The gallery is staffed by Explainers who are available to demonstrate how exhibits work, conduct live experiments and perform shows to schools and the visiting public.
The Science Museum has made many exhibitions that tour travel around the world. "The Science Box" modern science series toured venues in the UK and Europe in the 1990s and from 1995 "The Science of Sport" appeared in various venues, in different ways, around the world. In 2005 The Science Museum teamed up with Fleming Media to set up "The Science of..." who develop and tour exhibitions including "The Science of Aliens", "The Science of Spying" and "The Science of Survival" .
In 2008, "The Science of Survival" exhibition opened to the public and allowed visitors to explore what the world might be like in 2050 and how humankind will meet the challenges of climate change and energy shortages.
The museum is next to the Natural History Museum and used to be connected to it by a public corridor, which is now closed. The closest London Underground station is South Kensington; a subway connects the museums to the station.
At the front of the museum to the east is Exhibition Road. Directly to the south is Museum Lane and the Natural History Museum. At the back is Queen's Gate and to the north is Imperial College.
Bezliudivka
Bezliudivka (; ) is a settlement in the Kharkiv Oblast (province) of eastern Ukraine. Situated on the river Udy (Seversky Donets Basin), 3 km south of Kharkiv, 3 km from the railway station Bezlyudivka. As of 2001, 9,693 people lived there.
Joué-du-Plain
Joué-du-Plain is a commune in the Orne department in north-western France. The commune was mentioned in 1216 by the name of "Jeum". There are 201 people living there. It is in size. The highest point in the commune is . The river l'Udon flows through the commune. The forest of Mancelliere is here. The community festival is 29 June.
The church in the commune is dedicated to Saints Gervais and Portais. The architectural elements are pointed arches, a Norman tower and Roman arches. The church was rebuilt in the Renaissance. Inside the church are sculptures of St. Gervais and Saint Portais made in the 18th century. Also, there is an 18th century sculpture of Saint Michael made in stone and painted. There are also sculpted wooden stalls, a statue of the Virgin Mary and a baptismal font made in the 18th century. The cemetery around the church has two 16th century entrances.
Another important place in the commune is Château de la Motte. The chateau is a 19th century building.
Joué-du-Plain has a legend that the lord of Chantelou killed his wife and her lover. The lord painted the front of his chateau with their blood. The farm called Baritaur is the former place of the lord called "Red House of Chante-lou"
Military taxonomy
Military taxonomy is an indexing tool or record-keeping template. It includes weapons, equipment, organizations, strategies, and tactics.
Military taxonomy can be used to analyze field missions and other activities. For example, a taxonomy of terrorism would include terms related to terrorists, terrorist groups, terrorist attacks, weapons, venues, and characteristics of terrorists and terrorist groups.
A taxonomy of terms that describes types of military actions is affected by how all elements are defined and used. Many military strategies can be analyzed using a taxonomy model.
Polar bond
In chemistry, a polar bond is a type of covalent bond between two or more dissimilar atoms, in which electrons are shared unequally. A covalent bond is the "strong" kind of bond that makes a molecule.
Electrons are negatively charged. If the two atoms share the electrons equally, then the negative charge is evenly spread out over the entire molecule, balanced out by the positive charges of the protons in the atoms' nuclei. This makes the entire molecule neutral - a non-polar bond, making a non-polar molecule. However, if one of the atoms is particularly greedy for electrons (called electronegativity), then its side of the bond will have more electrons. Therefore, that side of the bond will have a slightly negative charge, and the other side will have a slightly positive charge.
